centos php5.4安装方法：首先通过“yum install gcc -y yum install libicu-devel -y”等命令安装php5.4依赖；然后使用命令“make install”安装php5.4即可。

安装php5.4.45依赖
yum install gcc -y yum install libicu-devel -y yum install glibc-headers -y yum install gcc-c++ -y yum install -y epel-release yum install php-mcrypt libmcrypt libmcrypt-devel
两个不能一起安装,因为CentOs6默认的yum源没有 libmcrypt-devel这个包,只能借助epel的yum源,所以先安装epel,再安装
