以下的文章主要是介紹升級PHP到5.2，MySQL數據庫到5.1 centos5.3 ，centos5.4安裝webmin默認的為 MySQL 5.0,php5.1 我需要升級到MySQL5.1和php5.2(禁止php5.3)，的實際操作步驟。
給yum安裝rpmforge：
yum list MySQL php 發現都是最新版本了，看來標准的yum源沒有更新
- wget http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-3.noarch.rpm
- wget http://rpms.famillecollet.com/el5.i386/remi-release-5-7.el5.remi.noarch.rpm
- rpm -Uvh remi-release-5-7.el5.remi.noarch.rpm epel-release-5-3.noarch.rpm
- yum --enablerepo=remi list MySQL
發現可以升級到 MySQL 5.1.44-1.el5.remi
- yum --enablerepo=remi update MySQL
發現需要把php也一並升級到 5.3，
而zend optimizer 目前不支持 Php5.3，於是需要禁止升級php5.3
- vi /etc/yum.conf
最後一行增加
- exclude=php*5.3*
然後再yum --enablerepo=remi update MySQL數據庫，就看不到php的升級了
搞定：
- [[email protected] backup]# php -v 還是舊的5.1.6
- PHP 5.1.6 (cli) (built: Jan 13 2010 17:13:05)
- Copyright (c) 1997-2006 The PHP Group
- Zend Engine v2.1.0, Copyright (c) 1998-2006 Zend Technologies
- with Zend Extension Manager v1.2.2, Copyright (c) 2003-2007, by Zend Technologies
- with Zend Optimizer v3.3.3, Copyright (c) 1998-2007, by Zend Technologies
- [[email protected] backup]# MySQL -V 升級到5.1.44了
- MySQL Ver 14.14 Distrib 5.1.44, for redhat-linux-gnu (i686) using readline 5.1
升級MySQL 5.1.41-1之後,請執行下列動作:
(1)將原有的/etc/my.cnf備份,將/etc/my.cnf.rpmnew改 為my.cnf
2)升級table
- MySQL_upgrade -p
(3)自動修復table
- MySQLcheck --all-databases --check-upgrade --auto-repair -p
找到一個yum源，有php5.2
- rpm --import http://repo.webtatic.com/yum/RPM-GPG-KEY-webtatic-andy
- wget -P /etc/yum.repos.d/ http://repo.webtatic.com/yum/webtatic.repo
- yum --enablerepo=webtatic list php
發現有php5.2 和 php5.3可以升級，
OK，我們vi /etc/yum.conf 禁止升級php5.3
- vi /etc/yum.conf
最後一行增加
- exclude=php*5.3*
或者：
- yum --enablerepo=webtatic --exclude=php*5.3* list php
- yum --enablerepo=webtatic --exclude=php*5.3* update -y php
- [[email protected] backup]# php -v 升級到5.2.12了，收工！
- PHP 5.2.12 (cli) (built: Dec 17 2009 19:40:56)
- Copyright (c) 1997-2009 The PHP Group
- Zend Engine v2.2.0, Copyright (c) 1998-2009 Zend Technologies
- with Zend Extension Manager v1.2.2, Copyright (c) 2003-2007, by Zend Technologies
- with Zend Optimizer v3.3.3, Copyright (c) 1998-2007, by Zend Technologies
安裝完成後需要安裝php-devel和httpd-devel兩個組件
- yum --enablerepo=webtatic --exclude=php*5.3* install php-devel
- yum --enablerepo=webtatic --exclude=php*5.3* install httpd-devel
否則，以後會出錯。
yum-allowdowngrade 可以降級的插件：
- allow downgrade for yum:
- yum install yum-allowdowngrade
- Add a line to yum.conf:
- showdupesfromrepos=1
- After that list all php packages:
- yum list php
- If php 5.2.8 is available, remove new one:
- yum remove php
- and install an old one:
- yum --allow-downgrade install php-5.2.8
以上的相關內容就是對升級PHP到5.2，MySQL數據庫到5.1的介紹，望你能有所收獲。
