因此，我尝试从 MariaDB 5.5 升级到 10.0。（本质上是 MySQL 分支）安装说明说
yum remove mariadb-server mariadb-common mariadb-compat
然后重新安装新版本....但yum remove也删除了
php-mysql
php-pear-MDB2-Driver-mysql
现在，当我重新安装时php-msyql出现错误：
> yum install php-mysql
Loaded plugins: fastestmirror, replace

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
为什么甚至要求安装 php-common???我已经安装了：
>yum list installed|grep php
php-pear-MDB2.noarch 2.5.0-0.9.b5.el6 @epel
php-php-gettext.noarch 1.0.11-3.el6 @epel
php53u.i686 5.3.28-4.ius.centos6 @ius
php53u-cli.i686 5.3.28-4.ius.centos6 @ius
php53u-common.i686 5.3.28-4.ius.centos6 @ius
php53u-devel.i686 5.3.28-4.ius.centos6 @ius
php53u-gd.i686 5.3.28-4.ius.centos6 @ius
php53u-mbstring.i686 5.3.28-4.ius.centos6 @ius
php53u-mcrypt.i686 5.3.28-4.ius.centos6 @ius
php53u-pdo.i686 5.3.28-4.ius.centos6 @ius
php53u-pear.noarch 1:1.9.4-3.ius.centos6 @ius
php53u-zts.i686 5.3.28-4.ius.centos6 @ius
并且...我已经安装了 libcurl！
>yum list installed|grep libcurl
libcurl.i686 7.19.7-40.el6_6.3 @updates
libcurl-devel.i686 7.19.7-40.el6_6.3 @updates
Google 表示，此版本的 libcurl 包含 libcurl.so.4 而不是 3。我查看了我的系统，发现有一个从 3 到 4 的符号链接：
>ll /usr/lib/libcurl.so*
lrwxrwxrwx 1 root root 16 Jan 1 02:00 /usr/lib/libcurl.so -> libcurl.so.4.1.1
lrwxrwxrwx 1 root root 12 Feb 16 2014 /usr/lib/libcurl.so.3 -> libcurl.so.4
lrwxrwxrwx 1 root root 16 Jan 1 01:59 /usr/lib/libcurl.so.4 -> libcurl.so.4.1.1
-rwxr-xr-x 1 root root 346084 Dec 7 23:50 /usr/lib/libcurl.so.4.1.1
我注意到它libcurl.so.3指向一个不存在的文件，并将其更新为指向 4.1.1......但仍然没有运气。
我应该怎么办？？
看起来 yum 没有skip dependancy check，但我必须使用RPM -nodeps它来执行此操作。但人们说会发生不好的事情。
答案1
好的，我用以下方法解决了这个问题rpm --nodeps......
首先在rpmfind.net
wget ftp://rpmfind.net/linux/centos/6.6/os/i386/Packages/php-mysql-5.3.3-38.el6.i686.rpm
wget ftp://rpmfind.net/linux/centos/6.6/updates/i386/Packages/php-common-5.3.3-40.el6_6.i686.rpm
wget ftp://rpmfind.net/linux/centos/6.6/updates/i386/Packages/php-pdo-5.3.3-40.el6_6.i686.rpm
然后我运行了它们每一个，rpm -iv只是为了看看发生了什么，当然它们都抱怨缺少依赖项...所以我运行了它们，rpm -vi --nodeps现在一切正常。
