zabbix监控自带MySQL模板

首先需要修改Agent端的配置文件

vim /usr/local/zabbix/etc/zabbix_agentd.conf
	Include=/usr/local/zabbix/etc/zabbix_agentd.conf.d/*.conf    //将这条参数的#去掉注释
mkdir /usr/local/zabbix/scripts
vim /usr/local/zabbix/scripts/.my.cnf    //这个用户是zabbix获取数据的用户，需要授权登陆MySQL
	[mysql]
	host=localhost
	user=zabbix
	password=123456
	socket=/tmp/mysql.sock
	
	[mysqladmin]
	host=localhost
	user=zabbix
	password=123456
	socket=/tmp/mysql.sock
vim /usr/local/zabbix/etc/zabbix_agentd.conf.d/userparameter_mysql.conf
	UserParameter=mysql.status[*],echo "show global status where Variable_name='$1';" | HOME=/var/lib/zabbix mysql -N | awk '{print $$2}'
	UserParameter=mysql.size[*],bash -c 'echo "select sum($(case "$3" in both|"") echo "data_length+index_length";; data|index) echo "$3_length";; free) echo "data_free";; esac)) from information_schema.tables$([[ "$1" = "all" || ! "$1" ]] || echo " where table_schema=\"$1\"")$([[ "$2" = "all" || ! "$2" ]] || echo "and table_name=\"$2\"");" | HOME=/var/lib/zabbix mysql -N'
	UserParameter=mysql.ping,HOME=/usr/local/zabbix/scripts/ mysqladmin ping | grep -c alive
	UserParameter=mysql.version,mysql -V

第一个是.my.cnf的路径，第二个命令需要环境变量，如果没有就把这个命令软连接一下

ln -s /usr/local/mysql/bin/mysqladmin  /usr/local/bin/

数据库创建zabbix用户，并授权登陆

mysql> create user 'zabbix'@'localhost' identified by '123456';
mysql> grant select on *.* to 'zabbix'@'localhost';
mysql> flush privileges;

重启agent客户端，再到zabbix监控图上看有没有值，如果没有值看主机监控项信息处查看提示信息，根据信息去解决问题，如果配置没问题，这里会显示为已启用
