无法在Centos中安装mysqli [英] Can not install mysqli in Centos
问题描述
我无法安装Mysqli.
我正在使用Centos 6，apache 2.2.x和php 5.4 MySql 5.5.37-cll
我尝试过:
yum install php-pdo php-mysqli
我看到:
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: mirrors.clouvider.net
* elrepo: mirrors.coreix.net
* extras: centos.hyve.com
* updates: mirrors.coreix.net
Setting up Install Process
No package php-pdo available.
No package php-mysqli available.
Error: Nothing to do

在我的php.ini中的动态扩展"部分中，我没有安装任何模块(我认为).如果我错了，请纠正我. php.ini->动态扩展

顺便说一句，以上所有模块都是针对Windows的，我是否需要为Centos编辑/激活任何模块?我需要与数据库的mysql和mysqli连接.
更新
我用easyapache重建了Apache，并检查了mysqli扩展名.我将发布结果.
从上面发布的结果来看，它没有安装，因为它无法在服务器上配置的任何存储库中找到php-pdo软件包.似乎您已对存储库进行了更改，因为elrepo既不在我已安装的版本5发行版中也不在版本6中.
我建议您先列出这些存储库中可用的软件包，因为它们可能是以不同的名称打包的.运行yum list php*以查看php软件包的输出.然后百胜会告诉您哪些可用，已安装以及需要更新.
注意:如果您在共享主机上，则可能已经安装了PHP并将其映射到特定版本.通常，您会在软件包名称中看到版本号，因此php可能是php4安装，php5可能是php版本5.2及以下安装，php53可能是php版本5.3安装，是的，我什至看到映射到php版本5.3的php6软件包.因此，如果您的服务器上安装的PHP软件包的软件包名称中包含版本号，这并不会与众不同.确实取决于您要使用的存储库.

By the way, all the above module is for windows, Should I need to edit/activate any module for the Centos? I need mysql and mysqli connections to database.
Update
I rebuild the apache with easyapache and I check the mysqli extension. I'll post the results from that.
From the results you posted above, it's not installing because it can't find the php-pdo package in any of the repositories configured on your server. It looks like you have made changes to your repositories as elrepo is not in either the version 5 or 6 distributions that I have installed.
I would suggest you first list the packages availabe in these repositories as they may be packaged under a different name. Run yum list php* to see an output of php packages. Yum will then tell you what is available, installed, and needs updating.
Note: If you're on a shared host, chances are that PHP is already installed and mapped to a specific version. Often times, you'll see the version number in the package name, so php might be a php4 install, php5 might be a php version 5.2 and below install, php53 might be a php version 5.3 install, and yes I've even seen a php6 package mapped to php version 5.3. So it wouldn't be out of the ordinary if the PHP package installed on YOUR server includes a version number in the package name. Really depends on what repositories you're setup to use.
