Centos5.4中Yum升级mysql5.1和php5.2(禁止php5.3)---(转)

          centos5.3,centos5.4安装webmin默认的是 mysql 5.0,php5.1 我需要升级到mysql5.1和php5.2(禁止php5.3)，怎么办？

          给yum安装rpmforge：
          http://wiki.centos.org/AdditionalResources/Repositories/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

          http://download.fedora.redhat.com/pub/epel/5/i386/ 这里有些可用的库源

          wget http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.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-*.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，就看不到php的升级了

          搞定：
          [[email protected] backup]# php -v  还是旧的5.1.6

          [[email protected] 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，方法如下：
          http://www.webtatic.com/blog/2009/06/php-530-on-centos-5/


          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

          [[email protected] backup]# php -v  升级到5.2.12了，收工！

          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
          

          

          另一个yum升级php方法：

          rpm --import http://www.jasonlitka.com/media/RPM-GPG-KEY-jlitka
          vi /etc/yum.repos.d/utterramblings.repo

          [utterramblings]
          name=Jason's Utter Ramblings Repo
          baseurl=http://www.jasonlitka.com/media/EL$releasever/$basearch/
          enabled=0
          gpgcheck=1
          gpgkey=http://www.jasonlitka.com/media/RPM-GPG-KEY-jlitka

          yum --enablerepo=utterramblings --exclude=php*5.3* update -y php
