这篇文章主要给大家介绍了在centos7 下mysql重新启动mariadb的相关资料，文中介绍的非常详细，对大家具有一定的参考价值，需要的朋友们下面来一起看看吧。
前言
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。开发这个分支的原因之一是：甲骨文公司收购了mysql后，有将mysql闭源的潜在风险，因此社区采用分支的方式来避开这个风险。[3]
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。在存储引擎方面，10.0.9版起使用xtradb（名称代号为aria）来代替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) 试着去启动mysql服务，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
下面讲正确的步骤
# yum install mariadb-server -y systemctl stop mariadb.service # systemctl start mariadb.service # systemctl enable mariadb.service # mysql welcome to the mariadb monitor. commands end with ; or \g. your mariadb connection id is 10 server version: 5.5.44-mariadb mariadb server copyright (c) 2000, 2015, oracle, mariadb corporation ab and others. type 'help;' or '\h' for help. type '\c' to clear the current input statement. mariadb [(none)]>
搞定!
