我在CentOS 5.6上从命令行运行一个简单的测试脚本，其中的PHP包已从 <在所有其他情况下，PHP运行良好，但是当我打开时，PHP运行良好。

mysql_connect（）它失败，没有错误。

如果我执行

  $ php -m 
  

我没有看到MySQL作为已安装的模块。

但是我已经将 extension = mysql.so 添加到我的php.ini并重新启动。

'rpm -qa | grep php'

 php-5.3。 10-1.w5 
 php-cli-5.3.10-1.w5

你可以尝试使用--skip-broken来解决问题
你可以尝试运行：package-cleanup --problems 
 package-cleanup --dupes 
 rpm -Va --nofiles --nodigest 
程序包清理在yum-utils包中。 
  

解决方案

没有看到MySQL作为一个已安装的模块。 
  

您是否安装了它？

 ＃yum install php-mysql 
  

php from）。

编辑：

this：

  yum --enablerepo = webtatic install php-mysql 
  

这告诉yum从webtatic存储库（除了系统配置的存储库）获取软件包。如果您希望在启用系统的存储库中使用webtatic，请运行：

  yum --enablerepo = webtatic install webtatic-release 
  
 
I am running a simple test script from the command line on CentOS 5.6 with the PHP package installed from PHP 5.3 on CentOS/RHEL 5.6.

PHP runs fine in all other cases but when I hit mysql_connect() it fails without error. 

If I run 
$ php -m
I am not seeing MySQL as an installed module.

However I have added extension=mysql.so to my php.ini and rebooted.

 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.

解决方案
 I am not seeing MySQL as an installed module.
Did you install it?
# yum install php-mysql
(from the same repo you installed php from).

EDIT:

run this:
yum --enablerepo=webtatic install php-mysql
this tells yum to get the packages from webtatic repository (in addition to system configured repositories). If you want webtatic among system enabled repositories, run:
 yum --enablerepo=webtatic install  webtatic-release
