CentOS 通过yum来升级php到php5.6

在文章中，我们将展示在centOS系统下如果将php升级到5.6，之前通过yum来安装lamp环境，直接升级的话，提示没有更新包，也就是说默认情况下php5.3.3是最新

 

1.查看已经安装的php版本号

键入下面代码：

php -v
或者/usr/bin/php

出现下面代码： 

PHP 5.3.3 (cli) (built: Jul 9 2015 17:39:00)
Copyright (c) 1997-2010 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies

 

2.安装Remi跟EPEL RPM源

下载并安装，代码如下： 

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

 

下载之后：

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

 

然后对里面内容进行以下修改：

[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/mirrorenabled=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi

 

还有以下：

[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=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi

 

3.现在可以yum命令直接升级了

 输入以下代码

yum -y upgrade php*
大概是镜像问题。我得到了报错

Loading mirror speeds from cached hostfile
Could not retrieve mirrorlist http://rpms.remirepo.net/enterprise/6/php55/mirror error was
12: Timeout on http://rpms.remirepo.net/enterprise/6/php55/mirror: (28, 'Operation too slow. Less than 1 bytes/sec transfered the last 30 seconds')
错误：Cannot find a valid baseurl for repo: remi-php55

 

然后我yum update -y php*就好了    -_-无奈！

 

一旦更新完毕，再次查看php版本号 

php -v

 

出现以下信息 

 

PHP 5.6.30 (cli) (built: Jan 19 2017 08:09:42)
Copyright (c) 1997-2016 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies

 

 到此，php升级完毕
