關於Linux啓動Apache遇到的問題

1.啓動Apache遇到加載不到的模塊

httpd: Syntax error on line 153 of /usr/local/apache/conf/httpd.conf: Cannot load /usr/local/svn/libexec/mod_dav_svn.so into server: /usr/local/svn/libexec/mod_dav_svn.so: undefined symbol: dav_do_find_liveprop
在apache/conf/httpd.conf 裏面查找到加載到這兩個模塊，註釋掉

2.啓動Apache遇到端口占用問題

(98)Address already in use: AH00072: make_sock: could not bind to address [::]:80
(98)Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
AH00015: Unable to open logs

這是服務器裏面還有進程佔用了Apache監聽的80端口，

解決辦法：

1.ps - ef | grep 80 或者 netstat -ano 看下是哪一個進程佔用了80端口或者監聽衝突 

kill 掉這個進程

2.更換Apache的監聽端口

vi httpd.conf 文件修改Listen

3.啓動Apache遇到沒有監聽端口的問題

no listening sockets available, shutting down
AH00015: Unable to open logs
大意失荊州，配置的時候必定要仔細看！！！

這是因爲註釋掉了Listen 80 ，Apache再啓動的時候找不到監聽的端口。
