我正在尝试安装 php-pdo，但由于 php-common 总是失败
bash-3.2# yum install php-pdo
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* epel: fedora-epel.mirror.lstn.net

Error: Missing Dependency: php-common = 5.1.6-40.el5_9 is needed by package php-pdo-5.1.6-40.el5_9.i386 (base)
You could try using --skip-broken to work around the problem
You could try running: package-cleanup --problems
package-cleanup --dupes
rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.
安装 php-common 我得到：
bash-3.2# yum install php-common
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* epel: fedora-epel.mirror.lstn.net
Setting up Install Process
Package matching php-common-5.1.6-40.el5_9.i386 already installed. Checking for update.
Nothing to do
在这里和谷歌搜索过，但没有找到任何有用的方法
编辑：添加了新的存储库：
bash-3.2# yum install php-common
Loaded plugins: fastestmirror

答案1
看起来您已禁用除“epel”之外的所有存储库。如果要让 yum 正常工作，您必须启用“base”和“updates”。
并且您应该在 CentOS5 上切换到 php53* 包。
