**在mysql中创建监控用户**

命令行中输入密码是不太友好的，

<table> 
 <tbody>

验证测试

<table> 
 <tbody> 
  <tr> 
   <th> <p>[root@server1 zabbix_agentd.d]# /usr/sbin/zabbix_agentd -t mysql.ping -c /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf&nbsp;<br> mysql.ping [t|1]</p> <p>同时，在Server端也可以使用使用zabbix_get命令来测试从Server端获取指定的Client端的数据，如下：</p> <p>[root@zabbix ~]# zabbix_get -s 192.168.1.94 -p 10050 -k mysql.ping<br> 1</p> </th> 
  </tr> 
 </tbody>

<table> 
 <tbody> 
  <tr> 
   <th>systemctl restart zabbix-agent</th>
