如何在 CentOS 上使用 yum 將 PHP 5.1 升級到 PHP 5.3

使用百勝/CentOS。

問題是 php 5.1 已經安裝並正在執行，所以

百勝更新php

不工作！

我在網上四處尋找解決方案，但他們說要執行上述操作 =/

你會想要的yum install php53。不幸的是，您需要先刪除php（這是 php 5.1，見下文）。

php53 在CentOS 5.6 及更高版本中可用。它在 CentOS 5.5 和之前的版本中不可用，除非您通過第三方儲存庫。這就是為什麼 Serverfault 上的許多答案告訴您使用第三方儲存庫的原因——這不再是必要的了。

請注意，php53 有許多依賴項，因此您應該考慮將 CentOS 更新到最新的 CentOS 5.x 分支作為此次升級的一部分（在撰寫本文時為 CentOS 5.6）。這是 PHP 的一次重大升級，RedHat 強行通過，因為它們在 RHEL5.5 時已經落後於時代。

注意包是如何命名的php53，而phpphp 5.1 是：

$ yum info php53
