一、添加监控用户
mysql> grant all privileges on *.* to 'zabbix'@'localhost' identified by 'zabbix';
mysql> flush privileges;
二、添加UserParameter
vim /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf
加入如下内容:
UserParameter=mysql.status[*],echo "show global status where Variable_name='$1';" | HOME=/etc/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=/etc/zabbix mysqladmin ping | grep -c alive
三、添加mysql连接信息
vim /etc/zabbix/.my.cnf
[mysql]
host=localhost
user=zabbix
password=zabbix
socket=/tmp/mysql.sock
[mysqladmin]
host=localhost
user=zabbix
password=zabbix
socket=/tmp/mysql.sock
四、重启zabbix-agent服务
systemctl restart zabbix-agent
五、去zabbix的管理界面添加MySQL的监控
选在主机：
添加MySQL监控模板：
