1：整合apache和php
（1）： 

# vi /usr/local/apache2/conf/httpd.conf

 
（2）：在AddType application/x-gzip .gz .tgz下边添加

# AddType application/x-httpd-php .php
# AddType application/x-httpd-php-source .phps

（ 注意.php前有一个空格）

 把DirectoryIndex index.html改成
 DirectoryIndex index.html index.php

2：/usr/local/apache2/bin/apachectl start
安装PHP后启动apache，启动提示：httpd: Syntax error on line 53 of
/usr/local/apache2/conf/httpd.conf: Cannot load
/usr/local/apache2/modules/libphp5.so into server:
/usr/local/apache2/modules/libphp5.so: cannot restore segment prot after
reloc: Permission denied
 
1：看看权限，ROOT，2：检查libphp5.so是否存在；3：关闭selinux
关闭：

# vi /etc/sysconfig/selinux 

 
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#       enforcing - SELinux security policy is enforced.
#       permissive - SELinux prints warnings instead of enforcing.
#       disabled - SELinux is fully disabled.
SELINUX=enforcing 
# SELINUXTYPE= type of policy in use. Possible values are:
#       targeted - Only targeted network daemons are protected.
#       strict - Full SELinux protection.
SELINUXTYPE=targeted
改为SELINUX=disable
重启后生效


要不重启的话，执行命令：

# setenforce 0

 
就可以不重启关闭selinux了，推荐先关闭，然后再输入命令，这样不用重启，下次重启后也就自动关闭了！
