JMeter连接数据库常见问题

1、防火墙未关

错误：

Communications link failure

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

问题：

防火墙未关

解决办法：

[root@localhost Desktop]# service iptables off
Usage: iptables {start|stop|restart|condrestart|status|panic|save}
[root@localhost Desktop]# service iptables stop
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
iptables: Unloading modules:                               [  OK  ]

=》另外，以上命令只是临时生效。服务器重启后，还是会默认打开防火墙。

永久生效，需要另行配置或写入到头文件。

2、密码错误（mysql）

Access denied for user 'root'@'192.168.1.100' (using password: YES)
