修改/etc/my.cnf文件创建无密码登录(把下面的配置添加进入)
user=zabbix
password=zabbix
host=192.168.254.128
user=zabbix
password=zabbix
测试是否可以直接访问不需要输入密码，如果输入命令 直接进去说明已OK。
# mysql -uzabbix -h192.168.254.128

现在数据库端 测试 是否可以查看到相关数据
mysqladmin extended-status |grep -w "Bytes_received" |cut -d"|" -f3 ###有数据返回说明正常
# mysqladmin extended-status |grep -w "Bytes_received" |cut -d"|" -f3

修改zabbix_agentd.conf添加以下参数：
vi /etc/zabbix/zabbix_agentd.conf （没有的就添加）
PidFile=/tmp/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=0

UserParameter=mysql.status[],/etc/zabbix/scripts/chk_mysql.sh $1
UserParameter=mysql.ping,/usr/local/mysql/bin/mysqladmin -uzabbix ping | grep -c alive
重启zabbix_agentd客户端服务，查看有没有报错。
# /etc/init.d/zabbix-agent restart
Restarting zabbix-agent (via systemctl): [确定]
在zabbix_server端的浏览器设置
收下在zabbix_server端查看下mysql脚本信息是否可以正常获取
# /usr/local/zabbix/bin/zabbix_get -s 192.168.254.128 -p10050 -k mysql.status
