前言

MariaDB數(shù)據(jù)庫(kù)管理系統(tǒng)是MySQL的一個(gè)分支，主要由開(kāi)源社區(qū)在維護(hù)，采用GPL授權(quán)許可。開(kāi)發(fā)這個(gè)分支的原因之一是：甲骨文公司收購(gòu)了MySQL后，有將MySQL閉源的潛在風(fēng)險(xiǎn)，因此社區(qū)采用分支的方式來(lái)避開(kāi)這個(gè)風(fēng)險(xiǎn)。[3]

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。在存儲(chǔ)引擎方面，10.0.9版起使用XtraDB（名稱(chēng)代號(hào)為Aria）來(lái)代替MySQL的InnoDB

# yum install mysql -y
# mysql
ERROR 2002 (HY000): Can"t connect to local MySQL server through socket "/var/lib/mysql/mysql.sock" (111)
試著去啟動(dòng)mysql服務(wù)，仍然不行
 
# systemctl start mysql
Failed to issue method call: Unit mysql.service failed to load: No such file or directory.
 
# systemctl start mysql.service
Failed to issue method call: Unit mysql.service failed to load: No such file or directory
 
# systemctl enable mysql.service
Failed to issue method call: Access denied

下面講正確的步驟

# yum install mariadb-server -y
systemctl stop mariadb.service
 
# systemctl start mariadb.service
# systemctl enable mariadb.service
# mysql

搞定!
