为了不影响实验效果，提前可以把selinux 和iptables 关闭
[root@localhost ~]# chkconfig iptables off
[root@localhost ~]# chkconfig ip6tables off
[root@localhost ~]# /etc/init.d/iptables stop
[root@localhost ~]# /etc/init.d/ip6tables stop
[root@localhost ~]# sed -i "s/LINUX=.*/LINUX=disabled/g" /etc/selinux/config
更改完selinux后要想生效需要重启一下服务器，reboot或者shutdown -r now
第一步 安装yum扩展源
# yum install -y epel-release
备注：6.7前版本不支持，需要下一步
# wget -P /etc/yum.repos.d/ http://mirrors.aliyun.com/repo/epel-6.repo
第二步 安装依赖包
# yum install make apr* autoconf automake gcc gcc-c++ zlib-devel openssl openssl-devel pcre-devel gd kernel keyutils patch perl kernel-headers compat* mpfr cpp glibc libgomp libstdc++-devel ppl cloog-ppl keyutils-libs-devel libcom_err-devel libsepol-devel libselinux-devel krb5-devel libXpm* freetype libjpeg* libpng* php-common php-gd ncurses* libtool* libxml2 libxml2-devel patch libmcrypt-devel php-mcrypt libmcrypt mcrypt freetype-devel freetype bzip2-devel bzip2-libs libxml2 libxml2-devel libxml2-python
把这些包全部安装上就不会报错了，
第三步 安装php
1，下载
# cd /usr/local/src/
# wget http://cn2.php.net/distributions/php-5.4.45.tar.bz2
2，解压
# tar -jxvf php-5.4.45.tar.bz2
3，安装
# cd php-5.4.45
# ./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2/bin/apxs --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-bz2 --with-openssl --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-mbstring --enable-sockets --enable-exif --disable-ipv6
如果出现报错:sorry,i cannot run apxs.possible reasons follow:
解决方法：
# find / -name perl
/usr/bin/perl
#vim /usr/local/apache2/bin/apxs
把第一行改成 #!/usr/bin/perl -w
#make && make install && echo $?
# cp /usr/local/src/php-5.4.45/php.ini-production /usr/local/php/etc/php.ini
拷贝配置文件
测试
# apachectl -M
php5_module (shared)
检测php安装是否成功，用apache -M 查看apache动态模块是否加载php5
网页测试
Apache主配置文件为：/usr/local/apache2/conf/httpd.conf
# vim /usr/local/apache2/conf/httpd.conf
# If the AddEncoding directives above are commented-out, then you
# probably should define those extensions to indicate media types:
#
AddType application/x-compress .Z
AddType application/x-gzip .gz .tgz
AddType application/x-httpd-php .php (定义apache解析PHP)
#
#
DirectoryIndex index.html index.php
#
[root@lanmp php-5.4.45]# cd /usr/local/apache2/htdocs/
[root@lanmp htdocs]# vi info.php
[root@lanmp htdocs]# cat info.php
phpinfo();
?>
在ie中输入 http://ip/info.php
