httpd启动中遇到的问题及解决方法

1.  warning:httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
解决方法：
在啟動 httpd 時出現

Starting httpd: httpd: apr_sockaddr_info_get() failed for MYHOST
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName.

這個問題應該是沒有在 /etc/httpd/conf/httpd.conf 中設定 ServerName 所以它會用主機上的名稱來取代，首先會去找 /etc/hosts 中有沒有主機的定義。

所以要解決這個問題可以設定 ServerName 或者在 /etc/hosts 中填入自己的主機名稱 MYHOST，像這樣：

>vi /etc/hosts

127.0.0.1 localhost.localdomain localhost MYHOST

2. 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
原因：80端口被占用
解决方法：
 netstat -lnp|grep 80
找到id之后kill
