CentOS6.2安裝php5.2.17

CentOS6.2的PHP版本是5.3，一些舊程式無法正常執行。
以下為將PHP改安裝5.2.17版的方式

1. 移除原先的php5.3及相關套件。(我一開始沒安裝php，所以就略過這步)
2. 到以下網址下載php5.2.17的相關套件
   32位元：http://www6.atomicorp.com/channels/atomic/centos/6/i386/RPMS/
   64位元：http://www6.atomicorp.com/channels/atomic/centos/6/x86_64/RPMS/
   我作業系統是32位元的，所以下載以下32位元的檔案
   (可依自己需要，選擇自己需要的下載即可)
   可將下列連結儲存成文字檔，例如 test.txt，再用 wget -i test.txt 指令批次下載回來

3. 安裝下載回來的php5.2.17
   rpm --oldpackage -Uvh php*
4. 我安裝時出現了相依性的問題
   

   錯誤：相依性偵測失敗：
           autoconf 被 php-devel-5.2.17-1.el6.art.i686 所需要
           automake 被 php-devel-5.2.17-1.el6.art.i686 所需要
           libXpm.so.4 被 php-gd-5.2.17-1.el6.art.i686 所需要
           libt1.so.5 被 php-gd-5.2.17-1.el6.art.i686 所需要
           libc-client.so.2007 被 php-imap-5.2.17-1.el6.art.i686 所需要

           libtidy-0.99.so.0 被 php-tidy-5.2.17-1.el6.art.i686 所需要
   

5. 嘗試安裝其他相依的套件，但有些原來的CentOS6.2沒有，
   所以又下載了 atomic-release-1.0-14.el6.art.noarch.rpm 安裝。
   rpm -Uvh atomic-release*rpm
   32位元：
   http://www6.atomicorp.com/channels/atomic/centos/6/i386/RPMS/atomic-release-1.0-14.el6.art.noarch.rpm
   64位元：
   http://www6.atomicorp.com/channels/atomic/centos/6/x86_64/RPMS/atomic-release-1.0-14.el6.art.noarch.rpm
6. 再安裝一次其他相依的套件
   yum install autoconf automake libXpm.so.4 libt1.so.5 libc-client.so.2007 libmcrypt.so.4 libmhash.so.2 libsybdb.so.5 libodbc.so.2 libpq.so.5 libaspell.so.15  libpspell.so.15 librecode.so.0 libtidy-0.99.so.0
7. 安裝php5.2.17
   rpm --oldpackage -Uvh php*
8. 安裝完可用以下指令查看PHP版本
   php -v
9. 將yum的更新排除PHP
   編輯/etc/yum.conf
   vi /etc/yum.conf
   在最後新增一行
   exclude=php*
   儲存後可用
   yum check-update | grep php  檢查是否還有PHP更新的資料
