一些常见错误技术问题汇总
一般出现这种问题有两种情况： 1.在apache安装目录conf下httpd.conf里可能重复了一行LoadModule php5_module modules/libphp5.so,删除重复的行就行。 2.或者在其他的conf文件中加载load了,如下yum安装的httpd，conf.d/php.conf里Q: 启动apache报错 [warn] module php5_module is already loaded, skipping
LoadModule php5_module modules/libphp5.so
Q: centos 6.2 更新报错解决 yum you could try using skip broken to work around the problem

the problem ** Found 1 pre-existing rpmdb problem(s), 'yum check' output follows: libvpx-1.0.0-1.el6.x86_64 is a duplicate with libvpx-0.9.0-8.el6_0.x86_64上述更新错误，解决方法如下：
yum remove matahari*执行完后，然后执行yun update 更新，这样应该就可以了。
Q: Cannot load /…/libphp5.so into server: /…/libphp5.so: undefined symbol: _efree
此错误是由于重装php时，没有关闭apache。解决方法：调转到php安装目录，执行“make clean”，然后从新安装php，记得安装之前关闭apache。
Q: apache启动报错(98)Address already in use: make_sock: could not bind to address :80
端口占用情况： #netstat -lnp|grep 80 #ps 端口号为80的进程 #kill -9 端口号为80的进程(可能进程不止一个)
这是由于configure过一次，没有清理干净，需要清理。可以删除掉源码目录，重新解压源码，重新安装，或者make clean.Q: 从源码安装apache2，遇到错误:cannot install `libaprutil-1.la'
