Centos6.8通过REMI升级PHP5.4到PHP5.6

In this article, I'm going to show you how to upgrade PHP 5.3 to PHP 5.6 on CentOS 6.7.

This article assumes you have a stock installation of CentOS, and that you already have PHP 5.3 installed

1. Verify current version of PHP

Type in the following to see the current PHP version:

php -v

Should output something like:

PHP 5.3.3 (cli) (built: Jul 9 2015 17:39:00)
Copyright (c) 1997-2010 The PHP Group

Great, now we can move on!

2. Install the Remi and EPEL RPM repositories

If you haven't already done so, install the Remi and EPEL repositories

wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm && rpm -Uvh epel-release-latest-6.noarch.rpm

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

Enable the REMI repository globally:

nano /etc/yum.repos.d/remi.repo

Under the section that looks like [remi] make the following changes:

[remi]
name=Remi's RPM repository for Enterprise Linux 6 - $basearch
#baseurl=http://rpms.remirepo.net/enterprise/6/remi/$basearch/
mirrorlist=http://rpms.remirepo.net/enterprise/6/remi/mirrorled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi

Also, under the section that looks like [remi-php55] make the following changes:

[remi-php56]
name=Remi's PHP 5.6 RPM repository for Enterprise Linux 6 - $basearch
#baseurl=http://rpms.remirepo.net/enterprise/6/php56/$basearch/
mirrorlist=http://rpms.remirepo.net/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

Type CTRL-O to save and CTRL-X to close the editor

3. Upgrade PHP 5.3 to PHP 5.6

Now we can upgrade PHP. Simply type in the following command:

yum -y upgrade php*

Once the update has completed, let's verify that you have PHP 5.6 installed:

php -v

Should see output similar to the following:

PHP 5.6.14 (cli) (built: Sep 30 2015 14:07:43)
Copyright (c) 1997-2015 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2015 Zend Technologies

You're done!
