本篇内容主要讲解“Ubuntu下怎么安装配置MariaDB”,感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷,实用性强。下面就让小编来带大家学习“Ubuntu下怎么安装配置MariaDB”吧!
MariaDB数据库管理系统是 MySQL 的一个分支,主要由开源社区在维护,采用GPL授权许可 MariaDB的目的是完全兼容MySQL,包括API和命令行,使之能轻松成为MySQL的代替品。
安装MariaDB
wuxiangping@linuxcool:~$ sudo apt updatewuxiangping@linuxcool:~$ sudo apt install mariadb-server
安装完成后,MariaDB服务将自动启动。
验证数据库服务器运行状态
wuxiangping@linuxcool:~$ sudo systemctl status mariadb.service
查看数据库版本号
wuxiangping@linuxcool:~$ mysql --versionmysql Ver 15.1 Distrib 10.1.44-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2
MariaDB安全配置,初始化数据
MariaDB服务器软件包自带一个名为mysql_secure_installation的脚本,可以轻松提高数据库服务器的安全性。
wuxiangping@linuxcool:~$ sudo mysql_secure_installationNOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!In order to log into MariaDB to secure it, we'll need the currentpassword for the root user. If you've just installed MariaDB, andyou haven't set the root password yet, the password will be blank,so you should just press enter here.Enter current password for root (enter for none):OK, successfully used password, moving on...Setting the root password ensures that nobody can log into the MariaDBroot user without the proper authorisation.You already have a root password set, so you can safely answer 'n'.Change the root password? [Y/n] yNew password:Re-enter new password:Password updated successfully!Reloading privilege tables..... Success!By default, a MariaDB installation has an anonymous user, allowing anyoneto log into MariaDB without having to have a user account created forthem. This is intended only for testing, and to make the installationgo a bit smoother. You should remove them before moving into aproduction environment.Remove anonymous users? [Y/n] y... Success!Normally, root should only be allowed to connect from 'localhost'. Thisensures that someone cannot guess at the root password from the network.Disallow root login remotely? [Y/n] y... Success!By default, MariaDB comes with a database named 'test' that anyone canaccess. This is also intended only for testing, and should be removedbefore moving into a production environment.Remove test database and access to it? [Y/n] y- Dropping test database...... Success!- Removing privileges on test database...... Success!Reloading the privilege tables will ensure that all changes made so farwill take effect immediately.Reload privilege tables now? [Y/n] y... Success!Cleaning up...All done! If you've completed all of the above steps, your MariaDBinstallation should now be secure.Thanks for using MariaDB!
本地root用户登录
shell与MariaDB交互操作,运行时会提示输入系统用户名的密码
wuxiangping@linuxcool:~$ sudo mysql[sudo] wuxiangping 的密码:Welcome to the MariaDB monitor. Commands end with ; or \g.Your MariaDB connection id is 49Server version: 10.1.44-MariaDB-0ubuntu0.18.04.1 Ubuntu 18.04Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.MariaDB [(none)]>
授权MariaDB指定主机远程访问
默认监听端口是127.0.0.1,需要修改为主机IP
wuxiangping@linuxcool:~$ sudo vim /etc/mysql/mariadb.conf.d/50-server.cnfbind-address=192.168.3.22
MariaDB [(none)]> use mysql;Reading table information for completion of table and column namesYou can turn off this feature to get a quicker startup with -ADatabase changedMariaDB [mysql]> GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.3.8' IDENTIFIED BY 'password' WITH GRANT OPTION;Query OK, 0 rows affected (0.00 sec)MariaDB [mysql]> flush privileges;Query OK, 0 rows affected (0.00 sec)MariaDB [mysql]> select host, user from user;
重启mariadb服务
wuxiangping@linuxcool:~$ sudo systemctl restart mariadb.service
远程主机连接测试
