centos通过yum安装php的教程
先给大家介绍下centos通过yum安装php
1、添加php的yum软件仓库
sudo rpm-Uvh
2、安装php相关软件，执行过程中全部选择yes即可
sudo yum install php71w.x86_64 php71w-cli.x86_64 php71w-common.x86_64 php71w-gd.x86_64 php71w-ldap.x86_64 php71w-mbstring.x86_64 php71w-mcrypt.x86_64 php71w-mysql.x86_64 php71w-pdo.x86_643、安装php71-fpm
sudo yum install php71w-fpm.x86_64
等待安装完成输入php-version查看php版本
ps:下面看下CentOS 7下Yum安装PHP7.2步骤
1、安装源
安装php72w，是需要配置额外的yum源地址的，否则会报错不能找到相关软件包。
php高版本的yum源地址，有两部分，其中一部分是epel-release，另外一部分来自webtatic。如果跳过epel-release的话，安装webtatic的时候，会有错误爆出。
所以，这里需要的命令是：
rpm-Uvh
rpm-Uvh
当然，您也可以选择下面的这个命令，也是一样的效果。
yum install epel-release-y
rpm-Uvh
2、清除历史版本
为了防止CentOS上面发生php冲突，所以，这个命令还是先执行一下更好些。
yum-y remove php*
3、安装扩展包
事实上，这里面的对应扩展库很多，这里大家一定要注意cli和fpm这两个包，而其它的相关包就看您需要了。
yum-y install php72w php72w-cli php72w-fpm php72w-common php72w-devel还有比较豪华的版本：
yum-y install php72w php72w-cli php72w-fpm php72w-common php72w-devel php72w-embedded php72w-gd php72w-mbstring php72w-mysqlnd php72w-opcache php72w-pdo php72w-xml4、安装完成以后，启动服务
systemctl enable php-fpm.service
systemctl start php-fpm.service5、安装成功
总结

阿里云上的centos 7.2怎么yum安装php 5.6
因之前通过网易的 centos镜像，将阿里云的 centos升级到最新版了，乘自己的项目尚未开始正式开发，遂将所有的相应环境都升级到最高。
查看 centos版本：
[root@iZ23d~]# cat/etc/centos-release
CentOS Linux release 7.2.1511(Core)
1、删除之前的 php版本：
[root@iZ23d~]# yum remove php* php-common
Loaded plugins: langpacks
Repository base is listed more than once in the configuration
Repository updates is listed more than once in the configuration
Repository extras is listed more than once in the configuration
Repository centosplus is listed more than once in the configuration
No Match for argument: php-5.4.16
No Match for argument: php-5.4.16.tar.gz

No Match for argument: php-7.0.1RC1.tar.gz
No Match for argument: phpMyAdmin-4.4.0.tar.gz
No Match for argument: php-common
No Packages marked for removal
2、rpm安装 Php7相应的 yum源：
[root@iZ23d~]# rpm-Uvh
Retrieving

4、检查 php版本：
[root@iZ23d~]# php-v

[root@iZ23d2e6hoqZ~]#
以上显示安装成功！
5、重启 Apache，查看 phpinfo:
[root@iZ23d~]# systemctl restart httpd.service
检查phpinfo:
