在一测试服务器（CentOS Linux release 7.2.1511）上安装MySQL 5.6（5.6.19 MySQL Community Server）时遇到下面错误，这个是因为CentOS 7的默认数据库已经不再是MySQL了，而是MariaDB. MySQL安装时的mysql lib库与mariadb的库、包冲突了，如下详情所示（省略了大量日志）

[root@azrlnx06 tmp]# rpm -ivh MySQL-server-advanced-5.6.20-1.rhel5.x86_64.rpm Preparing... ################################# [100%]file /usr/share/mysql/czech/errmsg.sys from install of MySQL-server-advanced-5.6.20-1.rhel5.x86_64 conflicts with file from package mariadb-libs-1:5.5.50-1.el7_2.x86_64file /usr/share/mysql/danish/errmsg.sys from install of MySQL-server-advanced-5.6.20-1.rhel5.x86_64 conflicts with file from package mariadb-libs-1:5.5.50-1.el7_2.x86_64file /usr/share/mysql/dutch/errmsg.sys from install of MySQL-server-advanced-5.6.20-1.rhel5.x86_64 conflicts with file from package mariadb-libs-1:5.5.50-1.el7_2.x86_64file /usr/share/mysql/english/errmsg.sys from install of MySQL-server-advanced-5.6.20-1.rhel5.x86_64 conflicts with file from package mariadb-libs-1:5.5.50-1.el7_2.x86_64file /usr/share/mysql/estonian/errmsg.sys from install of MySQL-server-advanced-5.6.20-1.rhel5.x86_64 conflicts with file from package mariadb-libs-1:5.5.50-1.el7_2.x86_64file /usr/share/mysql/french/errmsg.sys from install of MySQL-server-advanced-5.6.20-1.rhel5.x86_64 conflicts with file from package mariadb-libs-1:5.5.50-1.el7_2.x86_64file /usr/share/mysql/german/errmsg.sys from install of MySQL-server-advanced-5.6.20-1.rhel5.x86_64 conflicts with file from package mariadb-libs-1:5.5.50-1.el7_2.x86_64file /usr/share/mysql/greek/errmsg.sys from install of MySQL-server-advanced-5.6.20-1.rhel5.x86_64 conflicts with file from package mariadb-libs-1:5.5.50-1.el7_2.x86_64........................................................................................................................................................................file /usr/share/mysql/charsets/macroman.xml from install of MySQL-server-advanced-5.6.20-1.rhel5.x86_64 conflicts with file from package mariadb-libs-1:5.5.50-1.el7_2.x86_64file /usr/share/mysql/charsets/swe7.xml from install of MySQL-server-advanced-5.6.20-1.rhel5.x86_64 conflicts with file from package mariadb-libs-1:5.5.50-1.el7_2.x86_64

检查是否存在mariadb的相关组件,然后删除mariadb相关组件。如下所示：

[root@azrlnx06 mysql]# more /etc/redhat-release CentOS Linux release 7.2.1511 (Core) [root@azrlnx06 mysql]# rpm -qa |grep mariadbmariadb-libs-5.5.50-1.el7_2.x86_64[root@azrlnx06 mysql]# rpm -e mariadb-libs-5.5.50-1.el7_2.x86_64error: Failed dependencies:libmysqlclient.so.18()(64bit) is needed by (installed) postfix-2:2.10.1-6.el7.x86_64libmysqlclient.so.18(libmysqlclient_18)(64bit) is needed by (installed) postfix-2:2.10.1-6.el7.x86_64[root@azrlnx06 mysql]# rpm -e mariadb-libs-5.5.50-1.el7_2.x86_64 --nodeps

当然此处删除mariadb-libs-5.5.50-1.el7_2.x86_64组件时遇到依赖错误，遂强制删除该组件，最好使用yum删除mariadb相关组件。然后重新安装MySQL时遇到"error: MySQL-server-advanced-5.6.20-1.rhel5.x86_64: install failed"错误，如下所示：
