一、MySQL数据库配置
1.1 创建Mysql数据库用户
root@mysql \~\]# mysql -uroot -p create user zabbix@'127.0.0.1' identified by '123456'; flush privileges;
1.2 添加用户密码到mysql client的配置文件中
root@mysql \~\]# vim /etc/my.cnf.d/client.cnf \[client
host='127.0.0.1'
user='zabbix'
password='123456'
二、创建自定义监控脚本
root@mysql \~\]# vim /etc/zabbix/script/check_mysql.sh
bash
#!/bin/bash
#Mysql主机地址
MYSQL_HOST='127.0.0.1'
#Mysql端口
MYSQL_PORT='3306'
#数据连接
MYSQL_CONN="/usr/bin/mysqladmin -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 $1 in
Uptime)
result=`${MYSQL_CONN} status|cut -f2 -d":"|cut -f1 -d"T"`
echo $result
;;
Com_update)
result=`${MYSQL_CONN} extended-status |grep -w "Com_update"|cut -d"|" -f3`
echo $result
;;
Slow_queries)
result=`${MYSQL_CONN} status |cut -f5 -d":"|cut -f1 -d"O"`
echo $result
;;
Com_select)
result=`${MYSQL_CONN} extended-status |grep -w "Com_select"|cut -d"|" -f3`
echo $result
;;
Com_rollback)
result=`${MYSQL_CONN} extended-status |grep -w "Com_rollback"|cut -d"|" -f3`
echo $result
;;
Questions)
result=`${MYSQL_CONN} status|cut -f4 -d":"|cut -f1 -d"S"`
echo $result
;;
Com_insert)
result=`${MYSQL_CONN} extended-status |grep -w "Com_insert"|cut -d"|" -f3`
echo $result
;;
Com_delete)
result=`${MYSQL_CONN} extended-status |grep -w "Com_delete"|cut -d"|" -f3`
echo $result
;;
Com_commit)
result=`${MYSQL_CONN} extended-status |grep -w "Com_commit"|cut -d"|" -f3`
echo $result
;;
Bytes_sent)
result=`${MYSQL_CONN} extended-status |grep -w "Bytes_sent" |cut -d"|" -f3`
echo $result
;;
Bytes_received)
result=`${MYSQL_CONN} extended-status |grep -w "Bytes_received" |cut -d"|" -f3`
echo $result
;;
Com_begin)
result=`${MYSQL_CONN} extended-status |grep -w "Com_begin"|cut -d"|" -f3`
echo $result
;;
*)
echo "Unknown options."
;;
esac
三、zabbix agent添加自定义键值
root@mysql \~\]# vim /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf UserParameter=mysql.status\[\*\],bash /etc/zabbix/script/check_mysql.sh $1 UserParameter=mysql.ping,/usr/bin/mysqladmin ping 2\>/dev/null \| grep -c alive UserParameter=mysql.version,/usr/bin/mysql -V \[root@mysql \~\]# systemctl restart zabbix-agent
四、链接Mysql模板
配置-->主机-->添加模板-->选择"Template DB MySQL"


五、数据查看
