centos7安装MariaDB教程,分享给大家

1.centos7现状:

  新系统无法再使用yum install mysql-server来安装mysql,因为已使用mariadb代替mysql。

2.安装mariadb:

  1. [root@localhost ~]# yum -y install mariadb*
  2. Loaded plugins: fastestmirror
  3. Loading mirror speeds from cached hostfile
  4.      * base: mirrors.linode.com
  5.      * extras: mirrors.linode.com
  6.      * updates: mirrors.linode.com

  143. NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
  144.      SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
  145.  
  146. In order to log into MariaDB to secure it, we'll need the current
  147. password for the root user. If you've just installed MariaDB, and
  148. you haven't set the root password yet, the password will be blank,
  149. so you should just press enter here.
  150.  
  151. ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
  152. Enter current password for root (enter for none):
  153. OK, successfully used password, moving on...
  154.  
  155. Setting the root password ensures that nobody can log into the MariaDB
  156. root user without the proper authorisation.
  157.  
  158. Set root password? [Y/n] y
  159. New password:
  160. Re-enter new password:
  161. Password updated successfully!
  162. Reloading privilege tables..
  163.      ... Success!
  164.  
  165.  
  166. By default, a MariaDB installation has an anonymous user, allowing anyone
  167. to log into MariaDB without having to have a user account created for
  168. them. This is intended only for testing, and to make the installation
  169. go a bit smoother. You should remove them before moving into a
  170. production environment.
  171.  
  172. Remove anonymous users? [Y/n] y
  173.      ... Success!
  174.  
  175. Normally, root should only be allowed to connect from 'localhost'. This
  176. ensures that someone cannot guess at the root password from the network.
  177.  
  178. Disallow root login remotely? [Y/n] y
  179.      ... Success!
  180.  
  181. By default, MariaDB comes with a database named 'test' that anyone can
  182. access. This is also intended only for testing, and should be removed
  183. before moving into a production environment.
  184.  
  185. Remove test database and access to it? [Y/n] y
  186.      - Dropping test database...
  187.      ... Success!
  188.      - Removing privileges on test database...
  189.      ... Success!
  190.  
  191. Reloading the privilege tables will ensure that all changes made so far
  192. will take effect immediately.
  193.  
  194. Reload privilege tables now? [Y/n] y
  195.      ... Success!
  196.  
  197. Cleaning up...
  198.  
  199. All done! If you've completed all of the above steps, your MariaDB
  200. installation should now be secure.
  201.  
  202. Thanks for using MariaDB!
