3.安装php

[root@lly ~]# tar -zxvf php-5.4.3.tar.gz -C /usr/local/src/

[root@lly ~]# cd /usr/local/src/php-5.4.3/

[root@lly php-5.4.3]# ./configure --prefix=/usr/local/php --sysconfdir=/etc --with-apxs2=/usr/local/apache/bin/apxs --with-zlib --with-gd --with-jpeg-dir --with-png-dir --enable-mbstring --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --enable-xml --with-freetype-dir

[root@lly php-5.4.3]# make && make install

[root@lly php-5.4.3]# cd /usr/local/php/

[root@lly php]# vim /etc/profile

[root@lly php]# vim /etc/ld.so.conf.d/php.conf

写入

/usr/local/mysql/lib

[root@lly php]# ldconfig

[root@lly php]# ln -s include /usr/include/php

[root@lly php]# vim /etc/httpd/httpd.conf

在apache的配置文件中会自动添加modules/libphp5.so模块

[root@lly ~]# service httpd restart重启apache

注意：若出现如下错误，可能是是Linux有一个SELinux保护模式引起的

starting apache......httpd: Syntax error on line 147 of /etc/httpd/httpd.conf: Cannot load modules/libphp5.so into server: /usr/local/apache/modules/libphp5.so: cannot restore segment prot after reloc: Permission denied

Fail

可以进行如下操作

1关闭SELINUX的方法:
vi /etc/selinux/config 将SELINUX=enforcing 改成SELINUX=disabled

需要重启
这个方法可能会对服务器带来风险。

2不关闭SELINUX的方法:
# setenforce 0
# chcon -c -v -R -u system_u -r object_r -t textrel_shlib_t /usr/local/apache/modules/libphp5.so
# service httpd restart
# setenforce 1

[root@lly ~]# cd /usr/local/apache/htdocs apache的默认站点目录
