Docker部署Zabbix监控MariaDB主从同步(Percona Monitoring Plugins for Zabbix)

一、安装Docker并部署Zabbix

  建议先配置清华大学的docker-ce yum源,速度有保障:清华大学repo源

1.Zabbix Server节点配置

  部署环境:

[root@server0 ~]# docker -v
Docker version 18.09.1, build 4c52b90
[root@server0 ~]# cat /proc/version 
Linux version 3.10.0-693.el7.x86_64 (builder@kbuilder.dev.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) ) #1 SMP Tue Aug 22 21:09:27 UTC 2017
[root@server0 ~]# cat /etc/redhat-release 
CentOS Linux release 7.4.1708 (Core)

  启动并开机自运行Docker:

systemctl enable docker
systenctl start docker

  部署MySQL Docker,提供Zabbix数据库服务:

~]$ docker container run --name zmysql-server \
--network zabbix \
-e MYSQL_DATABASE="zabbix" \
-e MYSQL_USER="zabbix" \
-e MYSQL_PASSWORD="123456" \
-e MYSQL_ROOT_PASSWORD="654321" \
-v /data/zabbix-mysql:/var/lib/mysql \
--rm #根据需要也可以使用--restart=always
-d mysql:5.7

  部署Zabbix_server和Zabbix_web:

~]$ docker container run --name zabbix-server-mysql \
--network zabbix -t \
-e  DB_SERVER_HOST="172.20.0.2" \
-e MYSQL_DATABASE="zabbix" \
-e MYSQL_USER="zabbix" \
-e MYSQL_PASSWORD="123456" \
-e MYSQL_ROOT_PASSWORD="654321" \
-p 10051:10051 \
--rm -d zabbix/zabbix-server-mysql:centos-3.0-latest 
~]$ docker container run --name zabbix-nginx \
--network zabbix -t \
-e DB_SERVER_HOST="172.20.0.2" \
-e MYSQL_DATABASE="zabbix" \
-e MYSQL_USER="zabbix" \
-e ZBX_SERVER_HOST="172.20.0.3" \
-e MYSQL_PASSWORD="123456" \
-e MYSQL_ROOT_PASSWORD="654321" \
-e PHP_TZ="Asia/Shanghai" \
-p 80:80 --rm \
-d zabbix/zabbix-web-nginx-mysql:centos-3.0-latest

  修改时区:

docker container exec -ti zabbix-server-mysql /bin/bash
cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

  访问宿主机的IP就能访问zabbix了,使用容器部署服务是非常方便快捷的。部署zabbix的自运行脚本放在了我的github,可以直接运行脚本启动安装Zabbix。

2.在MariaDB主从节点上部署Zabbix-agent

  在MariaDB主从节点上设置授权zabbix能访问数据的账号,登录数据库执行:

> GRANT PROCESS,SUPER,REPLICATION CLIENT ON *.* TO zabbix@127.0.0.1 IDENTIFIED BY '123456';

  配置zabbix官方yum源并安装zabbix-agent,PHP、php-mysql:

[zabbix]
name=Zabbix Official Repository - $basearch
baseurl=http://repo.zabbix.com/zabbix/3.0/rhel/7/$basearch/
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX

[zabbix-non-supported]
name=Zabbix Official Repository non-supported - $basearch
baseurl=http://repo.zabbix.com/non-supported/rhel/7/$basearch/
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX
gpgcheck=0
yum install -y zabbix-agent zabbix-senter php php-mysql

二、安装Percona Monitoring Plugins插件监控MariaDB

  Percona Monitoring Plugins是一个很强大的数据库测试插件,我们这里只用它的MariaDB For Zabbix模板。

~]# rpm -ivh https://www.percona.com/redir/downloads/percona-release/redhat/latest/percona-release-0.1-6.noarch.rpm
~]# yum install percona-zabbix-templates -y
~]# rpm -ql percona-zabbix-templates #安装监控模板
/var/lib/zabbix/percona
/var/lib/zabbix/percona/scripts
/var/lib/zabbix/percona/scripts/get_mysql_stats_wrapper.sh
/var/lib/zabbix/percona/scripts/ss_get_mysql_stats.php
/var/lib/zabbix/percona/templates
/var/lib/zabbix/percona/templates/userparameter_percona_mysql.conf
/var/lib/zabbix/percona/templates/zabbix_agent_template_percona_mysql_server_ht_2.0.9-sver1.1.8.xml

  修改模板文件配置参数(红色字体为要修改的部分):

~]# cp /var/lib/zabbix/percona/templates/userparameter_percona_mysql.conf /etc/zabbix/zabbix_agentd.d/
~]# vim /var/lib/zabbix/percona/scripts/get_mysql_stats_wrapper.sh
if [ "$ITEM" = "running-slave" ]; then
    # Check for running slave
    RES=`HOME=~zabbix /usr/bin/mysql -uzabbix -p123456 -e 'SHOW SLAVE STATUS\G' | egrep '(Slave_IO_Running|Slave_SQL_Running):' | awk -F: '{print $2}' | tr '\n' ','`
    if [ "$RES" = " Yes, Yes," ]; then
        echo 1
    else
        echo 0
    fi
    exit
~]# vim /var/lib/zabbix/percona/scripts/ss_get_mysql_stats.php
$mysql_user = 'zabbix';
$mysql_pass = '123456';
~]# systemctl restart zabbix-agent.service

  测试,若以下命令返回任意数字,则说明模板配置成功:

~]# /var/lib/zabbix/percona/scripts/get_mysql_stats_wrapper.sh gg
~]# /var/lib/zabbix/percona/scripts/get_mysql_stats_wrapper.sh running-slave
~]# /usr/bin/php -q /var/lib/zabbix/percona/scripts/ss_get_mysql_stats.--host localhost --items gg

  登录Zabbix页面并导入模板:

  将xml模板文件上传至zabbix-server,由于官方的模板文件只支持zabbix2.0,这里提供修改后的3.0模板文件→→Zabbix Percona Template。导入后重zabbix-agent,添加主机和模板,设置触发器等等功能,然后就能监控MariaDB了。Percona的模板很详细,可以满足生产中决大部分MariaDB监控需求。
