监控Mysql没有数据，zabbix-get报错

rods

按照教程配置，用脚本取值的，脚本直接运行正常，但主机没有数据，日志也没错误，zabbix-get就显示错误，不明白哪里出错
脚本直接运行结果如下
[root@localhost zabbix]# ./mysqlcheck.sh Uptime
15963
用Zzbbix_get取值就出错，但我mariadb运行正常
[root@localhost zabbix]# zabbix_get -s 127.0.0.1 -k mysql.status[Uptime]
/usr/bin/mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (13)'
Check that mysqld is running and that the socket: '/var/lib/mysql/mysql.sock' exists!
脚本配置
