  • 解决CentOS7 无法启动mysql 的解决办法

    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 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!
