centos7 升级 php 5.4 -> php5.6

centos7 自带php5.4，升级到php5.6的方法：
https://webtatic.com/packages/php56/

CentOS/RHEL 7.x:

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

CentOS/RHEL 6.x:

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el6/latest.rpm

Now you can install PHP 5.6’s mod_php SAPI (along with an opcode cache) by doing:

yum install php56w php56w-opcache

You can alternatively install PHP 5.6’s php-fpm SAPI (along with an opcode cache by doing:

yum install php56w-fpm php56w-opcache

If you know what you are doing, you can upgrade PHP by:

yum install yum-plugin-replace
yum replace php-common --replace-with=php56w-common

执行完毕之后，重启php-fpm、nginx

systemctl restart php-fpm nginx

[root@vue~]# php-fpm -v
