zabbix3.2监控mysql性能

安装agent

DB权限

1. 在客户端的mysql里添加权限,使用zabbix账号连接本地的mysql

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

编辑 my.cnf

/etc/zabbix/etc/my.cnf (需新建)

#zabbix Agent
[mysql]
host=localhost
user=zabbix
password=zabbix
socket=/var/lib/mysql/mysql.sock  #具体根据个人情况
[mysqladmin]
host=localhost
user=zabbix
password=zabbix
socket=/var/lib/mysql/mysql.sock

修改agentd

/etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf
HOME=/var/lib/zabbix 修改为 HOME=/etc/zabbix/etc/

其他
zabbix_agentd.conf配置文件中
Include选择要包含 zabbix_agentd.d

service zabbix-agent restart

然后去web端口,添加主机 套用内置mysql模板就可以了.

关于userparameter_mysql.conf

还有一种配置

新建脚本

vim /etc/zabbix/chk_mysql.sh

#!/bin/bash
# 用户名
MYSQL_USER='zabbix'
# 密码
MYSQL_PWD='zabbix'
# 主机地址/IP
MYSQL_HOST='127.0.0.1'
# 端口
MYSQL_PORT='3306'
# 数据连接
MYSQL_CONN="/usr/bin/mysqladmin -u${MYSQL_USER} -p${MYSQL_PWD} -h${MYSQL_HOST} -P${MYSQL_PORT}"
# 参数是否正确
if [ $# -ne "1" ];then 
    echo "arg error!" 
fi 
# 获取数据
case $1 in

esac

修改配置

vim /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf

#UserParameter=mysql.status[*],echo "show global status where Variable_name='$1';" | HOME=/var/lib/zabbix mysql -N | awk '{print $$2}'
