(1) 列出所有被安装的rpm package

# rpm -qa | grep mariadbmariadb-libs-5.5.50-1.el7_2.x86_64mariadb-5.5.50-1.el7_2.x86_64mariadb-server-5.5.50-1.el7_2.x86_64

(2) 卸载

# rpm -e mariadb-libs-5.5.50-1.el7_2.x86_64

此时报错：

error: Failed dependencies:    libmysqlclient.so.18()(64bit) is needed by (installed) postfix-2:2.10.1-6.el7.x86_64    libmysqlclient.so.18()(64bit) is needed by (installed) perl-DBD-MySQL-4.023-5.el7.x86_64    libmysqlclient.so.18()(64bit) is needed by (installed) php-mysql-5.4.16-36.3.el7_2.x86_64    libmysqlclient.so.18(libmysqlclient_18)(64bit) is needed by (installed) postfix-2:2.10.1-6.el7.x86_64    libmysqlclient.so.18(libmysqlclient_18)(64bit) is needed by (installed) perl-DBD-MySQL-4.023-5.el7.x86_64    libmysqlclient.so.18(libmysqlclient_18)(64bit) is needed by (installed) php-mysql-5.4.16-36.3.el7_2.x86_64    mariadb-libs(x86-64) = 1:5.5.50-1.el7_2 is needed by (installed) mariadb-1:5.5.50-1.el7_2.x86_64    mariadb-libs(x86-64) = 1:5.5.50-1.el7_2 is needed by (installed) mariadb-server-1:5.5.50-1.el7_2.x86_64

(3) 强制卸载，因为没有-nodeps

# rpm -e --nodeps mariadb-libs-5.5.50-1.el7_2.x86_64# rpm -e --nodeps mariadb-5.5.50-1.el7_2.x86_64# rpm -e --nodeps mariadb-server-5.5.50-1.el7_2.x86_64

(4) 然后可以安装mysql了。
