MariaDB为可替代MySQL的增强版本, 但在已安装了MySQL的情况下同时也能安装MariaDB. (这是有意义的, 例如你想从一个数据库/应用迁移到另一个数据库/应用中.)
以下是在已安装MySQL的情况下,安装MariaDB的主要步骤.
[root@mariadb-near-mysql ~]# cat /etc/issue CentOS release 6.2 (Final) [root@mariadb-near-mysql ~]# rpm -qa mysql* mysql-5.1.61-1.el6_2.1.x86_64 mysql-libs-5.1.61-1.el6_2.1.x86_64 mysql-server-5.1.61-1.el6_2.1.x86_64 [root@mariadb-near-mysql ~]# ps axf | grep mysqld 2072 pts/0 S+ 0:00 \_ grep mysqld 1867 ?
