我們為目前線上客戶安裝的Linux都是CentOs發行版，是一套穩定、同時也是許多企業正在運行的版本。

在CentOs所採用的PHP版本較為保守，可以看到如下評論(taken from DistroWatch) CentOS is a bit outdated with it’s PHP versions which as a PHP developer can be a pain in the ass!

PHP Current Version	CentOS 7.0-1406	CentOS 6.6
5.6.4	5.4.16	5.3.3

現在我們可以利用另一個Linux發行版本Fedora的project來改善PHP版本問題。我們需要補充兩個Repos。首先我們需要EPEL 再來需要Remi 。

Repo設置

先確認您的伺服器已經打開SSH通道，然後執行下面指令(您需要有執行指令的權限，如果有必要建議使用root操作，或是sudo):

在CentOS 7下(包含安裝EPEL)

wgethttp://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm
wgethttp://rpms.famillecollet.com/enterprise/remi-release-7.rpm
rpm -Uvh remi-release-7*.rpm epel-release-7*.rpm

如果您原本就已經裝過EPEL則執行下面指令：

wgethttp://rpms.famillecollet.com/enterprise/remi-release-7.rpm
rpm -Uvh remi-release-7*.rpm

在CentOS 6下(包含安裝EPEL)

wgethttp://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
wgethttp://rpms.famillecollet.com/enterprise/remi-release-6.rpm
rpm -Uvh remi-release-6*.rpm epel-release-6*.rpm

如果您原本就已經裝過EPEL則執行下面指令：

wgethttp://rpms.famillecollet.com/enterprise/remi-release-6.rpm
rpm -Uvh remi-release-6*.rpm

啟動程式庫(Repo,repository)

進行到目前為止，我們需要確認程式庫有被啟動，同時選訂我們想要安裝的版本。 We need to head over to /etc/yum.repos.d you should inside see a file called remi.repo.

使用您喜好的編輯器(Nano、Pico、Vi ...etc)開啟remi.repo這隻檔案，您將看到一部份參數。我們需要確認第一階段[remi]是啟用狀態。

[remi]
name=Les RPM de remi pour Enterprise Linux 6 - $basearch
#baseurl=http://rpms.famillecollet.com/enterprise/6/remi/$basearch/
mirrorlist=http://rpms.famillecollet.com/enterprise/6/remi/mirror
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi

這一行enabled=1確認要設定！在技術上現在是可以繼續進行PHP安裝，但是將只會取得PHP 5.4.X版本。這如果不是你要的，那麼跳到下一步驟！

If we want PHP 5.5 or PHP 5.6 we need to do a bit more work, further down in the repo.repo file you will see two additional sections [remi-php55] and [remi-php56], decide which PHP version you want to install and then enable the correct. So for PHP 5.6 we would change to:

[remi-php56]
name=Les RPM de remi de PHP 5.6 pour Enterprise Linux 6 - $basearch
#baseurl=http://rpms.famillecollet.com/enterprise/6/php56/$basearch/
mirrorlist=http://rpms.famillecollet.com/enterprise/6/php56/mirror
# WARNING: If you enable this repository, you must also enable "remi"
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi

Once you made your changes save your modified file and quit your editor.

Installing PHP

Now I’m assuming you don’t already have PHP installed, this bit is super simple.

sudo yum install php php-gd php-mysql php-mcrypt

So the above assumes you want MySQL, GD and Mcrypt support in your PHP, but you should see something like the below depending on which version of PHP you are trying to install:

Transaction Summary
================================================================================================================================
Install      11 Package(s)

As you can see PHP is installing version 5.5.20-2.el6.remi from the remi-php55 repo! Once you have hit Y to confirm the install restart apache and magical unicorns you have a better version of PHP!

You can also change your mind in the future by going back into the remi.repo file and enable a different PHP version and then run yum update and if you have moved from 5.5 to 5.6 it will upgrade PHP for you. If you want to downgrade for any reason you will need to remove PHP (sudo yum remove php*) and then reinstall the PHP modules you want.
