xinetd 不会启动

Mik*_*e B 3 linux centos xinetd

愚蠢的问题...我无法让 xinetd 在我的 Linux 机器(CENTOS 4.8)上启动。

我已经通过 yum 删除它并重新安装它。当我尝试启动、停止等时,我完全没有收到任何错误。

   [root@server ~]# service xinetd stop
   [root@server ~]# service xinetd start
   [root@server ~]# service xinetd restart

我希望从系统中看到一些标准状态(例如“服务已启动 - [确定]”我也没有在 /var/log/messages 中看到任何日志条目

我尝试使用 -d 选项运行 init 脚本,但没有。没有错误。没有服务启动的确认消息。没有什么。

有任何想法吗?

[更新] - 根据建议,这是 cat /etc/init.d/xinetd 的输出

如果完全绕过启动脚本并使用调试标志 -d 直接运行 xinetd,您可能会获得一些有用的信息。

/usr/sbin/xinetd -f /etc/xinetd.conf -d

在我的 Gentoo 盒子上,当我没有定义任何服务时,上面的命令将在下面的调试输出之后退出

09/10/26@21:26:05: DEBUG: 23117 {cnf_start_services} mask_max = 0, services_started = 0
09/10/26@21:26:05: CRITICAL: 23117 {init_services} no services. Exiting...

启用服务后(在本例中为 chargen,在 /etc/xinetd.d/chargen-stream 中将行“disable = yes”更改为“disable = no”)运行上述命令会产生以下输出,并且 xinetd 不会退出直到按下 Ctrl-c。

09/10/26@21:41:00: DEBUG: 23261 {cnf_start_services} Started service: chargen-stream
09/10/26@21:41:00: DEBUG: 23261 {cnf_start_services} mask_max = 6, services_started = 1

顺便说一句,如果您在启用 chargen 的情况下运行 init 脚本,那么您应该能够通过运行以下命令使用 netstat 来查看 xinetd 正在侦听 chargen 端口:

netstat -tap | grep xinetd

输出应如下所示:
