php升级5.3到5.4，5.5，5.6

Laravel要求php大于5.5.9，升级php5.3.3到5.6.14（最新版为 5.6.15 ）

Add EPEL and Remi repositories onto your system:

wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

rpm -Uvh remi-release-6*.rpm epel-release-6*.rpm

enable your newly added Remi repo. Open the /etc/yum.repos.d/remi.repo

在想要升级的版本里，enabled=0 line to enabled=1:

Update to PHP 5.4, in [remi] section:

Update to PHP 5.5, in [remi-php55] section:

Now update yum:

yum update -y  //这个会升级很多额

报错：

Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

编辑/etc/yum.repos.d/epel.repo，把基础的恢复，镜像的地址注释掉

编辑[epel]下的baseurl前的#号去掉，mirrorlist前添加#号

再次运行

yum update -y

最后检查

php -v

安装

1，

rpm -Uvh https://mirror.webtatic.com/yum/el6/latest.rpm

2，

yum install yum-plugin-replace

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

It will likely give you a message “WARNING: Unable to resolve all providers …”. This is normal, and you can continue by tying “y“. 

Done！
