MYSQL数据库出现这样问题是CentOS 7 版本将MySQL数据库软件从默认的程序列表中移除,用mariadb代替了 MYSQL数据库有两种解决办法： MYSQL数据库方法一：安装mariadb MYSQL数据库MariaDB数据库管理系统是MySQL的一个分支,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.MariaDB由MySQL的创始人Michael Widenius(英语：Michael Widenius)主导开发,他早前将自己创建的公司MySQL AB卖给了SUN,此后,随着SUN被甲骨文收购,MySQL的所有权也落入Oracle的手中.MariaDB名称来自Michael Widenius的女儿Maria的名字. MYSQL数据库安装mariadb,输入安装命令 MYSQL数据库[root@localhost home]# yum install mariadb-server mariadb MYSQL数据库
MYSQL数据库mariadb数据库的相关命令是： MYSQL数据库
systemctl start mariadb #启动MariaDB
systemctl stop mariadb #停止MariaDB
systemctl restart mariadb #重启MariaDB
systemctl enable mariadb #设置开机启动
MYSQL数据库先启动数据库 MYSQL数据库? [root@yl-web yl]# systemctl start mariadb MYSQL数据库默认无密码 MYSQL数据库
[root@localhost lzh]# mysql -u root -p
Enter password:
