This account is currently not available

[root@ servers]# service nagios restart
Running configuration check...done.
Stopping nagios: done.
Starting nagios:This account is currently not available.
 done.

提示：Starting nagios:This account is currently not available.

这是因为当时安装nagios没有设好权限，不过可以通过如下操作来完善它：

vi /etc/passwd

找到此行：nagios:x:500:500::/home/nagios:/sbin/nologin（注意红色字体），把此行改成如下一行

        nagios:x:500:500::/home/nagios:/bin/bash

[root@servers]# service nagios restart

Running configuration check...done.

Stopping nagios: done.

Starting nagios: done.

OK！问题搞定！！
