apache启动不了

为了使服务器的网络实现冗余，所以把外网的一台服务器做了双网卡聚合。操作后重启这台服务器上的httpd服务报错！

[root@test ~]# /etc/init.d/httpd start
Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
                                                           [FAILED]

采用以下方法恢复服务

[root@test ~]# ps -aux | grep apache

总结杀死全部apache进程，然后启动服务。

出现这种问题的原因，很有可能是操作系统本身已经安装了apache造成的。所以建议在安装操作系统时将原有的apache卸载掉。否则即便启动apache成功启动的也是系统本身安装的apache。
