Centos 6.6 Zabbix Server 2.4 with Nginx 1.6 and MySql 5.6

Starting from a minimal install.

step 1: enable extra repositories


yum install http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

yum install http://repo.zabbix.com/zabbix/2.4/rhel/6/x86_64/zabbix-release-2.4-1.el6.noarch.rpm

yum install http://dev.mysql.com/get/mysql-community-release-el6-5.noarch.rpm

yum install http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm

yum -y update

step 2: configure  mysql database


yum -y install mysql-server.x86_64

vim /etc/my.cnf

Your config file should be like these.

Note: I activate binlog without purge because can be useful if you need to recover data or attach a mysql slave.

secure mysql installation

/usr/bin/mysql_secure_installation

allow incoming 3306 connections


/sbin/iptables -A INPUT -i eth0 -p tcp --destination-port 3306 -j ACCEPT
service iptables save

step 3: configure database backup

This is important because after a lot of power outages and hard disk problems sometimes you can’t recover your database and restore a backup is faster than reinstall or the only way.


yum install wget pbzip2
mysql -uroot -p

create backup user


GRANT LOCK TABLES, SELECT ON *.* TO 'BACKUPUSER'@'%' IDENTIFIED BY 'PASSWORD';
flush privileges;
exit

install AutoMysqlBackup

wget http://www.mirrorservice.org/sites/downloads.sourceforge.net/a/au/automysqlbackup/AutoMySQLBackup/AutoMySQLBackup%20VER%203.0/automysqlbackup-v3.0_rc6.tar.gz
tar xzvf automysqlbackup-v3.0_rc6.tar.gz
/install.sh
mkdir /var/backup/
mkdir /var/backup/db

we need to adjust our config file


vim /etc/automysqlbackup/myserver.conf

should look like these

note: I select bzip because it gets better results

# This option sends a START TRANSACTION SQL statement to the server before dumping data. It is useful only with
# transactional tables such as InnoDB, because then it dumps the consistent state of the database at the time
# when BEGIN was issued without blocking any applications.
#
# When using this option, you should keep in mind that only InnoDB tables are dumped in a consistent state. For
# example, any MyISAM or MEMORY tables dumped while using this option may still change state.
#
# While a --single-transaction dump is in process, to ensure a valid dump file (correct table contents and
# binary log coordinates), no other connection should use the following statements: ALTER TABLE, CREATE TABLE,
# DROP TABLE, RENAME TABLE, TRUNCATE TABLE. A consistent read is not isolated from those statements, so use of
# them on a table to be dumped can cause the SELECT that is performed by mysqldump to retrieve the table
# contents to obtain incorrect contents or fail.
CONFIG_mysql_dump_single_transaction='yes'

# http://dev.mysql.com/doc/refman/5.0/en/mysqldump.html#option_mysqldump_master-data
# --master-data[=value]
# Use this option to dump a master replication server to produce a dump file that can be used to set up another
# server as a slave of the master. It causes the dump output to include a CHANGE MASTER TO statement that indicates
# the binary log coordinates (file name and position) of the dumped server. These are the master server coordinates
# from which the slave should start replicating after you load the dump file into the slave.
#
# If the option value is 2, the CHANGE MASTER TO statement is written as an SQL comment, and thus is informative only;
# it has no effect when the dump file is reloaded. If the option value is 1, the statement is not written as a comment
# and takes effect when the dump file is reloaded. If no option value is specified, the default value is 1.
#
# This option requires the RELOAD privilege and the binary log must be enabled.
#
# The --master-data option automatically turns off --lock-tables. It also turns on --lock-all-tables, unless
# --single-transaction also is specified, in which case, a global read lock is acquired only for a short time at the
# beginning of the dump (see the description for --single-transaction). In all cases, any action on logs happens at
# the exact moment of the dump.

#CONFIG_mysql_dump_master_data=

# Included stored routines (procedures and functions) for the dumped databases in the output. Use of this option
# requires the SELECT privilege for the mysql.proc table. The output generated by using --routines contains
# CREATE PROCEDURE and CREATE FUNCTION statements to re-create the routines. However, these statements do not
# include attributes such as the routine creation and modification timestamps. This means that when the routines
# are reloaded, they will be created with the timestamps equal to the reload time.
#
# If you require routines to be re-created with their original timestamp attributes, do not use --routines. Instead,
# dump and reload the contents of the mysql.proc table directly, using a MySQL account that has appropriate privileges
# for the mysql database.
#
# This option was added in MySQL 5.0.13. Before that, stored routines are not dumped. Routine DEFINER values are not
# dumped until MySQL 5.0.20. This means that before 5.0.20, when routines are reloaded, they will be created with the
# definer set to the reloading user. If you require routines to be re-created with their original definer, dump and
# load the contents of the mysql.proc table directly as described earlier.
#

# Store an additional copy of the latest backup to a standard
# location so it can be downloaded by third party scripts.
CONFIG_mysql_dump_latest='yes'

# Remove all date and time information from the filenames in the latest folder.
# Runs, if activated, once after the backups are completed. Practically it just finds all files in the latest folder
# and removes the date and time information from the filenames (if present).
CONFIG_mysql_dump_latest_clean_filenames='no'

# Create differential backups. Master backups are created weekly at #$CONFIG_do_weekly weekday. Between master backups,
# diff is used to create differential backups relative to the latest master backup. In the Manifest file, you find the
# following structure
# $filename     md5sum  $md5sum diff_id $diff_id        rel_id  $rel_id
# where each field is separated by the tabular character '\t'. The entries with $ at the beginning mean the actual values,
# while the others are just for readability. The diff_id is the id of the differential or master backup which is also in
# the filename after the last _ and before the suffixes begin, i.e. .diff, .sql and extensions. It is used to relate
# differential backups to master backups. The master backups have 0 as $rel_id and are thereby identifiable. Differential
# backups have the id of the corresponding master backup as $rel_id.
#
# To ensure that master backups are kept long enough, the value of $CONFIG_rotation_daily is set to a minimum of 21 days.

# Other

# Backup local files, i.e. maybe you would like to backup your my.cnf (mysql server configuration), etc.
# These files will be tar'ed, depending on your compression option CONFIG_mysql_dump_compression compressed and
# depending on the option CONFIG_encrypt encrypted.
#
# Note: This could also have been accomplished with CONFIG_prebackup or CONFIG_postbackup.

# and files rw------- permissions.
#umask 0077

# dry-run, i.e. show what you are gonna do without actually doing it
# inactive: =0 or commented out
# active: uncommented AND =1
#CONFIG_dryrun=1

at next step we add a cron line to run our backup every day


vim /etc/cron.daily/runmysqlbackup

the content should be like these


#!/bin/sh
/usr/local/bin/automysqlbackup /etc/automysqlbackup/myserver.conf
chown root.root /var/backup/db* -R
find /var/backup/db* -type f -exec chmod 400 {} \;
find /var/backup/db* -type d -exec chmod 700 {} \;

you should make your script executable


chmod +x /etc/cron.daily/runmysqlbackup

if you wanna try just execute


/etc/cron.daily/runmysqlbackup

and check /var/backup/db directory

and now you will have a daily backup 😛

Step 4: Install  zabbix server

 

yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent
service zabbix-server start
service zabbix-agent start
chkconfig zabbix-agent on

 

 

we need to create a zabbix database user and a zabbix database

mysql -uroot -p

 

execute these sentences

create database zabbix character set utf8 collate utf8_bin;
grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbixdatabasepasword';
flush privileges;
exit

 

next step is populate table structures

note: sql commands should changue check a should be in /usr/share/doc/zabbix-server-mysql-<version>/create


 mysql -uroot -p zabbix &amp;amp;lt; /usr/share/doc/zabbix-server-mysql-2.4.2/create/schema.sql
 mysql -uroot -p zabbix &amp;amp;lt; /usr/share/doc/zabbix-server-mysql-2.4.2/create/images.sql
 mysql -uroot -p zabbix &amp;amp;lt; /usr/share/doc/zabbix-server-mysql-2.4.2/create/data.sql

 

at this point we have out zabbix database its time to link zabbix and database


vim /etc/zabbix/zabbix_server.conf

 

your config file shoul be like these

its time to start our service and let it enabled


service zabbix-server start
chkconfig  zabbix-server on
setsebool -P zabbix_can_network 1

Step 4: Configure nginx and php-fpm server

We need to install several packages and open port 80 (http)


yum -y install nginx php-common php-fpm
/sbin/iptables -A INPUT -i eth0 -p tcp --destination-port 80 -j ACCEPT
service iptables save
chkconfig nginx on
chkconfig php-fpm  on
service nginx start
service php-fpm start

open a web browser and put your zabbix ip on it you should view a page like these

welcome nginx

we need to adjust some php values


vim /etc/php.ini

changue these values


max_execution_time = 300

max_input_time = 300
post_max_size = 16M

date.timezone = Europe/Madrid

cgi.fix_pathinfo=1

if you don’t live in Spain here you have a list of timezones http://php.net/manual/en/timezones.php

next step is add zabbix domain to nginx


vim /etc/nginx/conf.d/zabbix.conf

file should look like these


server {
server_name zabbix.example.org;

root        /var/www/zabbix;
index       index.html index.php;
access_log  /var/log/nginx/access_zabbix.log main;
error_log   /var/log/nginx/error_zabbix.log error

location ~ \.php {
include fastcgi_params;
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
#fastcgi_intercept_errors on;
fastcgi_pass    unix:/var/run/php-zabbix.socket;
fastcgi_index   index.php;
fastcgi_param   SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}

}

next step is configure zabbix in php-fpm pool


 mkdir /var/lib/php/zabbix_php-fpm

chmod 770 /var/lib/php/zabbix_php-fpm/

chown root:nginx /var/lib/php/zabbix_php-fpm/

 vim /etc/php-fpm.d/zabbix.conf

 

config file should be like these


; Start a new pool named 'zabbix'.
[zabbix]

; The address on which to accept FastCGI requests.
; Valid syntaxes are:
;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific address on
;                            a specific port;
;   'port'                 - to listen on a TCP socket to all addresses on a
;                            specific port;
;   '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
listen = /var/run/php-zabbix.socket

; Set listen(2) backlog. A value of '-1' means unlimited.
; Default Value: -1
;listen.backlog = -1

; List of ipv4 addresses of FastCGI clients which are allowed to connect.
; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original
; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each address
; must be separated by a comma. If this value is left blank, connections will be
; accepted from any ip address.
; Default Value: any
;listen.allowed_clients = 127.0.0.1

; Set permissions for unix socket, if one is used. In Linux, read/write
; permissions must be set in order to allow connections from a web server. Many
; BSD-derived systems allow connections regardless of permissions.
; Default Values: user and group are set as the running user
;                 mode is set to 0666
listen.owner = nginx
listen.group = nginx
listen.mode = 0666

; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
;       will be used.
; RPM: apache Choosed to be able to access some dir as httpd
user = nginx
; RPM: Keep a group allowed to write in log dir.
group = nginx

; Choose how the process manager will control the number of child processes.
; Possible Values:
;   static  - a fixed number (pm.max_children) of child processes;
;   dynamic - the number of child processes are set dynamically based on the
;             following directives:
;             pm.max_children      - the maximum number of children that can
;                                    be alive at the same time.
;             pm.start_servers     - the number of children created on startup.
;             pm.min_spare_servers - the minimum number of children in 'idle'
;                                    state (waiting to process). If the number
;                                    of 'idle' processes is less than this
;                                    number then some children will be created.
;             pm.max_spare_servers - the maximum number of children in 'idle'
;                                    state (waiting to process). If the number
;                                    of 'idle' processes is greater than this
;                                    number then some children will be killed.
; Note: This value is mandatory.
pm = dynamic

; The number of child processes to be created when pm is set to 'static' and the
; maximum number of child processes to be created when pm is set to 'dynamic'.
; This value sets the limit on the number of simultaneous requests that will be
; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.
; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP
; CGI.
; Note: Used when pm is set to either 'static' or 'dynamic'
; Note: This value is mandatory.
pm.max_children = 50

; The number of child processes created on startup.
; Note: Used only when pm is set to 'dynamic'
; Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2
pm.start_servers = 5

; The desired minimum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.min_spare_servers = 5

; The desired maximum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.max_spare_servers = 35

; The number of requests each child process should execute before respawning.
; This can be useful to work around memory leaks in 3rd party libraries. For
; endless request processing specify '0'. Equivalent to PHP_FCGI_MAX_REQUESTS.
; Default Value: 0
;pm.max_requests = 500

; The URI to view the FPM status page. If this value is not set, no URI will be
; recognized as a status page. By default, the status page shows the following
; information:
;   accepted conn    - the number of request accepted by the pool;
;   pool             - the name of the pool;
;   process manager  - static or dynamic;
;   idle processes   - the number of idle processes;
;   active processes - the number of active processes;
;   total processes  - the number of idle + active processes.
; The values of 'idle processes', 'active processes' and 'total processes' are
; updated each second. The value of 'accepted conn' is updated in real time.
; Example output:
;   accepted conn:   12073
;   pool:             www
;   process manager:  static
;   idle processes:   35
;   active processes: 65
;   total processes:  100
; By default the status page output is formatted as text/plain. Passing either
; 'html' or 'json' as a query string will return the corresponding output
; syntax. Example:
;  
;  
;  
; Note: The value must start with a leading slash (/). The value can be
;       anything, but it may not be a good idea to use the .php extension or it
;       may conflict with a real PHP file.
; Default Value: not set
;pm.status_path = /status

; The ping URI to call the monitoring page of FPM. If this value is not set, no
; URI will be recognized as a ping page. This could be used to test from outside
; that FPM is alive and responding, or to
; - create a graph of FPM availability (rrd or such);
; - remove a server from a group if it is not responding (load balancing);
; - trigger alerts for the operating team (24/7).
; Note: The value must start with a leading slash (/). The value can be
;       anything, but it may not be a good idea to use the .php extension or it
;       may conflict with a real PHP file.
; Default Value: not set
;ping.path = /ping

; This directive may be used to customize the response of a ping request. The
; response is formatted as text/plain with a 200 response code.
; Default Value: pong
;ping.response = pong

; The timeout for serving a single request after which the worker process will
; be killed. This option should be used when the 'max_execution_time' ini option
; does not stop script execution for some reason. A value of '0' means 'off'.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
;request_terminate_timeout = 0

; The timeout for serving a single request after which a PHP backtrace will be
; dumped to the 'slowlog' file. A value of '0s' means 'off'.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
;request_slowlog_timeout = 0

; The log file for slow requests
; Default Value: not set
; Note: slowlog is mandatory if request_slowlog_timeout is set
slowlog = /var/log/php-fpm/zabbix-slow.log

; Set open file descriptor rlimit.
; Default Value: system defined value
;rlimit_files = 1024

; Set max core size rlimit.
; Possible Values: 'unlimited' or an integer greater or equal to 0
; Default Value: system defined value
;rlimit_core = 0

; Chroot to this directory at the start. This value must be defined as an
; absolute path. When this value is not set, chroot is not used.
; Note: chrooting is a great security feature and should be used whenever
;       possible. However, all PHP paths will be relative to the chroot
;       (error_log, sessions.save_path, ...).
; Default Value: not set
;chroot =

; Chdir to this directory at the start. This value must be an absolute path.
; Default Value: current directory or / when chroot
;chdir = /var/www

; Redirect worker stdout and stderr into main error log. If not set, stdout and
; stderr will be redirected to /dev/null according to FastCGI specs.
; Default Value: no
catch_workers_output = yes

; Limits the extensions of the main script FPM will allow to parse. This can
; prevent configuration mistakes on the web server side. You should only limit
; FPM to .php extensions to prevent malicious users to use other extensions to
; exectute php code.
; Note: set an empty value to allow all extensions.
; Default Value: .php
security.limit_extensions = .php .php3 .php4 .php5

; Pass environment variables like LD_LIBRARY_PATH. All $VARIABLEs are taken from
; the current environment.
; Default Value: clean env
;env[HOSTNAME] = $HOSTNAME
;env[PATH] = /usr/local/bin:/usr/bin:/bin
;env[TMP] = /tmp
;env[TMPDIR] = /tmp
;env[TEMP] = /tmp

; Additional php.ini defines, specific to this pool of workers. These settings
; overwrite the values previously defined in the php.ini. The directives are the
; same as the PHP SAPI:
;   php_value/php_flag             - you can set classic ini defines which can
;                                    be overwritten from PHP call 'ini_set'.
;   php_admin_value/php_admin_flag - these directives won't be overwritten by
;                                     PHP call 'ini_set'
; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.

; Defining 'extension' will load the corresponding shared extension from
; extension_dir. Defining 'disable_functions' or 'disable_classes' will not
; overwrite previously defined php.ini values, but will append the new value
; instead.

; Default Value: nothing is defined by default except the values in php.ini and
;                specified at startup with the -d argument
;php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f www@my.domain.com
;php_flag[display_errors] = off
php_admin_value[error_log] = /var/log/php-fpm/zabbix-error.log
php_admin_flag[log_errors] = on
;php_admin_value[memory_limit] = 128M

; Set session path to a directory owned by process user
php_value[session.save_handler] = files
php_value[session.save_path] =  /var/lib/php/zabbix_php-fpm/
