Percona监控MySQL数据库

配置zabbix-agent

• 安装percona插件

yum -y install http://www.percona.com/downloads/percona-release/redhat/0.1-6/percona-release-0.1-6.noarch.rpm
yum -y install php php-mysql percona-zabbix-templates

• 拷贝配置文件并重启zabbix-agent

cp /var/lib/zabbix/percona/templates/userparameter_percona_mysql.conf /etc/zabbix_agentd.conf.d/userparameter_percona_mysql.conf
systemctl restart zabbix-agent

• 查看percona相关目录

rpm -ql percona-zabbix-templates
/var/lib/zabbix/percona
/var/lib/zabbix/percona/scripts
/var/lib/zabbix/percona/scripts/get_mysql_stats_wrapper.sh   # 脚本调用PHP
/var/lib/zabbix/percona/scripts/ss_get_mysql_stats.php       # PHP采集数据
/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   # 模板文件，3.x导入会报错

导入修改过的模板文件

配置MySQL连接

• 配置php连接数据库

mysql> GRANT USAGE, PROCESS, REPLICATION CLIENT ON *.* TO \'zabbix\'@\'localhost\' IDENTIFIED BY "zabbix00";
vim /var/lib/zabbix/percona/scripts/ss_get_mysql_stats.php.cnf
<?php
$mysql_user = \'zabbix\';
$mysql_pass = \'zabbix00\';

• 测试脚本

/var/lib/zabbix/percona/scripts/get_mysql_stats_wrapper.sh gg
73

• 配置~zabbix/.my.cnf

vim ~zabbix/.my.cnf
[client]
user=zabbix
password=\'zabbix00\'

• 测试脚本

sudo -u zabbix -H /var/lib/zabbix/percona/scripts/get_mysql_stats_wrapper.sh running-slave
# 结果为1或0为正常
