centos 6.5 php扩展怎么安装

CentOS下php安装mcrypt扩展 
 
（以下步骤均为本人实际操作，可能与你的安装方法有所区别，但我会尽量排除疑惑） 
 
大致步骤（1）安装mcrypt，（2）安装php对mcrypt的扩展，（3）重启apache 
 
（1）、确认你的linux没有安装mcrypt库，如果已安装，跳过安装步骤 
 
[root@test-206 ~]# yum list installed|grep mcrypt 
 
libmcrypt.x86_64                          2.5.8-4.el5.centos           installed 
 
libmcrypt-devel.x86_64                    2.5.8-4.el5.centos           installed 
 
mcrypt.x86_64                             2.6.8-1.el5                  installed 
 
以上显示已经安装过，若没有，则按以下两种方式安装 
 
yum命令懒人安装 
 
yum install libmcrypt libmcrypt-devel mcrypt mhash 
 
执行后会显示即将安装的相关库，你可以根据你的linux限定x86_64或者i386，如yum install  libmcrypt.x86_64（如果yum命令无法连接仓库，请检查你的/etc/yum.repos.d/里的文件正确性，以及你的/etc/host是不是可达里面的域名）
