Установка и настройка Zabbix-сервера на Centos

Март 1st, 2016

Evgeniy Kamenev

1.Добавление репозитария Zabbix
Отсюда скачиваем и устанавливаем пакет для добавления репозитария
http://repo.zabbix.com/zabbix/

Centos 6
64-бит(x86_64)

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

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

32-бит(i386)

# wget http://repo.zabbix.com/zabbix/2.4/rhel/6/i386/zabbix-release-2.4-1.el6.noarch.rpm

1	# wget http://repo.zabbix.com/zabbix/2.4/rhel/6/i386/zabbix-release-2.4-1.el6.noarch.rpm

Centos7

# wget http://repo.zabbix.com/zabbix/2.4/rhel/7/x86_64/zabbix-release-2.4-1.el7.noarch.rpm

1	# wget http://repo.zabbix.com/zabbix/2.4/rhel/7/x86_64/zabbix-release-2.4-1.el7.noarch.rpm

В моем случае Centos 6 x86_64

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

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

# rpm –Uhv zabbix-release-2.4-1.el6.noarch.rpm

1	# rpm –Uhv zabbix-release-2.4-1.el6.noarch.rpm

2.Установка Zabbix-сервера и Zabbix-агента(клиента)

# yum install zabbix-agent zabbix-server-mysql zabbix-web-mysql

1	# yum install zabbix-agent zabbix-server-mysql zabbix-web-mysql

Будет использоваться связка Nginx+PHP-FPM

3.Настройка PHP-FPM

Используем отдельный пул с пользователем zabbix

# egrep -v '(^;|^$)' /etc/php-fpm.d/zabbix.conf

1	# egrep -v '(^;\|^$)' /etc/php-fpm.d/zabbix.conf

[zabbix]
listen = /var/run/php5-fpm-zabbix.sock
listen.allowed_clients = 127.0.0.1
listen.owner = zabbix
listen.group = nginx
listen.mode = 0660
user = zabbix
group = zabbix
pm = dynamic

php_admin_flag[log_errors] = on
php_admin_value[memory_limit] = 128M
php_admin_value[max_execution_time] = 300
php_admin_value[post_max_size] = 16M
php_admin_value[upload_max_filesize] = 2M
php_admin_value[max_input_time] = 300
php_value[session.save_handler] = files
php_value[session.save_path] = /var/lib/php/session-zabbix

4.Настройка Nginx

# nano /etc/nginx/conf.d/zabbix.mydomain.com.conf

1	# nano /etc/nginx/conf.d/zabbix.mydomain.com.conf

server {
listen       <IP-address-server-external>:80;
server_name  zabbix.mydomain.com  *.zabbix.mydomain.com;
root   /usr/share/zabbix;

index index.php index.html index.html;
access_log /var/log/nginx/zabbix.mydomain.com.log  main;

location / {
        allow 127.0.0.1;
        allow 159.224.XXX.YYY;
        deny all;

location ~ \.php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+?\.php)(/.*)?$;
fastcgi_pass   unix:/var/run/php5-fpm-zabbix.sock;
fastcgi_index index.php;
fastcgi_buffers 4 256k;
fastcgi_busy_buffers_size 256k;
fastcgi_temp_file_write_size 256k;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include       fastcgi_params;
   }
location = /favicon.ico { access_log off; log_not_found off; }
location = /robots.txt { access_log off; log_not_found off; }
location ~ /\.ht { deny  all; }
  }
}

server {

}

# nginx –t

1	# nginx –t

# service nginx reload

1	# service nginx reload

# chown -R zabbix:zabbix /usr/share/zabbix

1	# chown -R zabbix:zabbix /usr/share/zabbix

# chown -R zabbix:zabbix /etc/zabbix/web/

1	# chown -R zabbix:zabbix /etc/zabbix/web/

5.Создаем базу данных zabbix и пользователя zabbix с доступом к этой базе

mysql> create database zabbix CHARACTER SET utf8 COLLATE utf8_bin;

1	mysql> create database zabbix CHARACTER SET utf8 COLLATE utf8_bin;

mysql> grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbixpassword ';

1	mysql> grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbixpassword ';

mysql> flush privileges;

1	mysql> flush privileges;

6.Заливаем стандартные схемы для базы zabbix

# mysql zabbix < /usr/share/doc/zabbix-server-mysql-2.4.7/create/schema.sql

1	# mysql zabbix < /usr/share/doc/zabbix-server-mysql-2.4.7/create/schema.sql

# mysql zabbix < /usr/share/doc/zabbix-server-mysql-2.4.7/create/images.sql

1	# mysql zabbix < /usr/share/doc/zabbix-server-mysql-2.4.7/create/images.sql

# mysql zabbix < /usr/share/doc/zabbix-server-mysql-2.4.7/create/data.sql

1	# mysql zabbix < /usr/share/doc/zabbix-server-mysql-2.4.7/create/data.sql

7.Настройка Zabbix-сервера
В WEB-интерфейсе http://zabbix.mydomain.com

database user – zabbix
database name – zabbix
databse password – zabbixpassword (пароль,который вводили во время создания zabbix-пользователя)
Zabbix server details
Host – localhost
Port – 10051
Name - Zabbix

database user – zabbix

database name – zabbix

databse password – zabbixpassword (пароль,который вводили во время создания zabbix-пользователя)

Zabbix server details

Host – localhost

Port – 10051

Name - Zabbix

После окончания установки

Стандартный логин — Admin ; пароль — zabbix

1	Стандартный логин — Admin ; пароль — zabbix

Настройка конфигурационного файла Zabbix-сервера

# cp /etc/zabbix/zabbix_server.conf /etc/zabbix/zabbix_server.conf~

1	# cp /etc/zabbix/zabbix_server.conf /etc/zabbix/zabbix_server.conf~

# egrep -v '^#|^$' /etc/zabbix/zabbix_server.conf

1	# egrep -v '^#\|^$' /etc/zabbix/zabbix_server.conf

ListenPort=10051
LogFile=/var/log/zabbix/zabbix_server.log
LogFileSize=0
DebugLevel=3
PidFile=/var/run/zabbix/zabbix_server.pid
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword= zabbixpassword
DBSocket=/var/lib/mysql/mysql.sock
DBPort=3306
SNMPTrapperFile=/var/log/snmptt/snmptt.log
AlertScriptsPath=/usr/lib/zabbix/alertscripts
ExternalScripts=/usr/lib/zabbix/externalscripts

ListenPort=10051

LogFile=/var/log/zabbix/zabbix_server.log

LogFileSize=0

DebugLevel=3

PidFile=/var/run/zabbix/zabbix_server.pid

DBHost=localhost

DBName=zabbix

DBUser=zabbix

DBPassword= zabbixpassword

DBSocket=/var/lib/mysql/mysql.sock

DBPort=3306

SNMPTrapperFile=/var/log/snmptt/snmptt.log

AlertScriptsPath=/usr/lib/zabbix/alertscripts

ExternalScripts=/usr/lib/zabbix/externalscripts

8.Настройка Zabbix-агента

# cp /etc/zabbix/zabbix_agentd.conf /etc/zabbix/zabbix_agentd.conf~

1	# cp /etc/zabbix/zabbix_agentd.conf /etc/zabbix/zabbix_agentd.conf~

# egrep -v '^#|^$' /etc/zabbix/zabbix_agentd.conf

1	# egrep -v '^#\|^$' /etc/zabbix/zabbix_agentd.conf

PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=0
DebugLevel=3
EnableRemoteCommands=1
LogRemoteCommands=1
Server=127.0.0.1
ListenPort=10050
ListenIP=0.0.0.0
StartAgents=3
ServerActive=127.0.0.1
Hostname=myserver.name
AllowRoot=0
User=zabbix
Include=/etc/zabbix/zabbix_agentd.d/

PidFile=/var/run/zabbix/zabbix_agentd.pid

LogFile=/var/log/zabbix/zabbix_agentd.log

LogFileSize=0

DebugLevel=3

EnableRemoteCommands=1

LogRemoteCommands=1

Server=127.0.0.1

ListenPort=10050

ListenIP=0.0.0.0

StartAgents=3

ServerActive=127.0.0.1

Hostname=myserver.name

AllowRoot=0

User=zabbix

Include=/etc/zabbix/zabbix_agentd.d/

9.Настройка iptables
Для доступа Zabbix-сервера к агенту при использовании пассивного режима(сервер подключается к клиенту(агенту) на порт 10050)

# iptables -A INPUT -p tcp  --dport 10050 -j ACCEPT

1	# iptables -A INPUT -p tcp --dport 10050 -j ACCEPT

Для доступа удаленных Zabbix-агентов(клиентов) при использовании активного режима(клиент подключается к серверу на порт 10051 и передает данные)

# iptables -A INPUT -p tcp  --dport 10051 -j ACCEPT

1	# iptables -A INPUT -p tcp --dport 10051 -j ACCEPT

Для доступа в Web-интерфейсу Zabbix-сервера

# iptables -A INPUT -p tcp --dport 80 -j ACCEPT

1	# iptables -A INPUT -p tcp --dport 80 -j ACCEPT

# service iptables save

1	# service iptables save

10.Добавление в автозагрузку сервера и агента, перезапуск служб, просмотр логов

# chkconfig --level 2345 zabbix-agent on

1	# chkconfig --level 2345 zabbix-agent on

# chkconfig --level 2345 zabbix-server on

1	# chkconfig --level 2345 zabbix-server on

# service zabbix-agent restart

1	# service zabbix-agent restart

# service zabbix-server restart

1	# service zabbix-server restart

# tail -n 50 -f /var/log/zabbix/zabbix_agentd.log /var/log/zabbix/zabbix_server.log

1	# tail -n 50 -f /var/log/zabbix/zabbix_agentd.log /var/log/zabbix/zabbix_server.log

11.Включение Zabbix-сервера на мониторинг самого себя

Configuration->Hosts->Zabbix server->Status->Enabled

1	Configuration->Hosts->Zabbix server->Status->Enabled
