在文章中,我們將展示在centOS系統下如果將php升級到5.6,之前通過yum來安裝lamp環境,直接升級的話,提示沒有更新包,也就是說默認情況下php5.3.3是最新
1.查看已經安裝的php版本號
鍵入下面代碼:
php -v
或者
/usr/bin/php
出現下面代碼:
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.安裝Remi跟EPEL RPM源
下載並安裝,代碼如下:
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
下載之后:
vim /etc/yum.repos.d/remi.repo
然后對里面內容進行以下修改:
[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/mirror enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi
還有以下:
[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=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi
3.現在可以yum命令直接升級了
輸入以下代碼
yum -y upgrade php*
大概是鏡像問題。我得到了報錯
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')
錯誤:Cannot find a valid baseurl for repo: remi-php55
然后我yum update -y php*就好了 -_-無奈!
一旦更新完畢,再次查看php版本號
php -v
出現以下信息
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升級完畢
