本篇內(nèi)容主要講解“Ubuntu下怎么安裝配置MariaDB”,感興趣的朋友不妨來看看。本文介紹的方法操作簡單快捷,實(shí)用性強(qiáng)。下面就讓小編來帶大家學(xué)習(xí)“Ubuntu下怎么安裝配置MariaDB”吧!
MariaDB數(shù)據(jù)庫管理系統(tǒng)是 MySQL 的一個(gè)分支,主要由開源社區(qū)在維護(hù),采用GPL授權(quán)許可 MariaDB的目的是完全兼容MySQL,包括API和命令行,使之能輕松成為MySQL的代替品。
wuxiangping@linuxcool:~$ sudo apt update wuxiangping@linuxcool:~$ sudo apt install mariadb-server
安裝完成后,MariaDB服務(wù)將自動(dòng)啟動(dòng)。
wuxiangping@linuxcool:~$ sudo systemctl status mariadb.service
wuxiangping@linuxcool:~$ mysql --version mysql Ver 15.1 Distrib 10.1.44-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2
MariaDB服務(wù)器軟件包自帶一個(gè)名為mysql_secure_installation的腳本,可以輕松提高數(shù)據(jù)庫服務(wù)器的安全性。
wuxiangping@linuxcool:~$ sudo mysql_secure_installation NOTE: 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 current password for the root user. If you've just installed MariaDB, and you 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 MariaDB root user without the proper authorisation. You already have a root password set, so you can safely answer 'n'. Change the root password? [Y/n] y New password: Re-enter new password: Password updated successfully! Reloading privilege tables.. ... Success! By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? [Y/n] y ... Success! Normally, root should only be allowed to connect from 'localhost'. This ensures 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 can access. This is also intended only for testing, and should be removed before 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 far will 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 MariaDB installation should now be secure. Thanks for using MariaDB!
shell與MariaDB交互操作,運(yùn)行時(shí)會(huì)提示輸入系統(tǒng)用戶名的密碼
wuxiangping@linuxcool:~$ sudo mysql [sudo] wuxiangping 的密碼: Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 49 Server version: 10.1.44-MariaDB-0ubuntu0.18.04.1 Ubuntu 18.04 Copyright (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)]>
默認(rèn)監(jiān)聽端口是127.0.0.1,需要修改為主機(jī)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 names You can turn off this feature to get a quicker startup with -A Database changed MariaDB [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;
重啟mariadb服務(wù)
wuxiangping@linuxcool:~$ sudo systemctl restart mariadb.service
