3、添加修改配置文件

1）查看

[root@zabbix /var/lib/zabbix/percona/templates]# ll

-rw-r--r-- 1 root root  18866 Jan 10  2018 userparameter_percona_mysql.conf
-rw-r--r-- 1 root root 269258 Jan 10  2018 zabbix_agent_template_percona_mysql_server_ht_2.0.9-sver1.1.8.xml

2）mv移动配置文件

[root@zabbix /var/lib/zabbix/percona/templates]# mv userparameter_percona_mysql.conf /etc/zabbix/zabbix_agentd.d/

3）重启zabbix客户端

systemctl restart zabbix-agent.service

4）修改php文件用户及密码

vim /var/lib/zabbix/percona/scripts/ss_get_mysql_stats.php
...
$mysql_user = 'zabbix';
$mysql_pass = '123456';
....

4、命令行取值

[root@zabbix /etc/zabbix/zabbix_agentd.d]# zabbix_get -s 127.0.0.1 -k MySQL.Open-files
