以下的文章主要是介绍升级PHP到5.2,MySQL数据库到5.1 centos5.3 ,centos5.4安装webmin默认的为 MySQL 5.0,php5.1 我需要升级到MySQL5.1和php5.2(禁止php5.3),的实际操作步骤。
给yum安装rpmforge:
yum list MySQL php 发现都是最新版本了,看来标准的yum源没有更新
- 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
发现可以升级到 MySQL 5.1.44-1.el5.remi
- yum --enablerepo=remi update MySQL
发现需要把php也一并升级到 5.3,
而zend optimizer 目前不支持 Php5.3,于是需要禁止升级php5.3
- vi /etc/yum.conf
最后一行增加
- exclude=php*5.3*
然后再yum --enablerepo=remi update MySQL数据库,就看不到php的升级了
搞定:
- [root@www.ctohome.com backup]# php -v 还是旧的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
- [root@www.ctohome.com backup]# MySQL -V 升级到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
找到一个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
发现有php5.2 和 php5.3可以升级,
OK,我们vi /etc/yum.conf 禁止升级php5.3
- vi /etc/yum.conf
最后一行增加
- 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
- [root@www.ctohome.com backup]# php -v 升级到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
安装完成后需要安装php-devel和httpd-devel两个组件
- yum --enablerepo=webtatic --exclude=php*5.3* install php-devel
- yum --enablerepo=webtatic --exclude=php*5.3* install httpd-devel
否则,以后会出错。
yum-allowdowngrade 可以降级的插件:
- 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
以上的相关内容就是对升级PHP到5.2,MySQL数据库到5.1的介绍,望你能有所收获。
