在centos 6安裝 mysql-server是直接使用命令 yum -y install mysql-server ,可是在CentOS 7中出現了 No package mysql-server available. Error: Nothing to do 錯誤。詳細錯誤信息以下:mysql
[root@laona ~]# yum -y install mysql-server Loaded plugins: fastestmirror Repository base is listed more than once in the configuration Repository updates is listed more than once in the configuration Repository extras is listed more than once in the configuration Repository centosplus is listed more than once in the configuration Repository contrib is listed more than once in the configuration Loading mirror speeds from cached hostfile * base: mirrors.cloud.aliyuncs.com * extras: mirrors.cloud.aliyuncs.com * updates: mirrors.cloud.aliyuncs.com No package mysql-server available. Error: Nothing to do
使用 MariaDB 代替 MySQL 命令便可sql
簡單來講,MariaDB 是 MySQL 的fork,二者關係就比如 Red Hat 和 CentOS 的關係。從 MySQL 變成了 Oracle 甲骨文公司的產品後,MySQL 就已經從 RHEL 和 CentOS 所提供的套件清單移除了。shell
sudo yum -y install mariadb mariasb-client
sudo systemctl start mariadb
sudo systemctl enable mariadb
sudo systemctl status mariadb
sudo mysql_secure_installation
這個shell主要是有如下做用:
- 設定 root 帳號的密碼
- 禁止 root 叢非本人登陸
- 移除 anonymous 匿名用戶登陸
- 移除測試數據庫數據庫
mysql -v
鍵入如下指令,輸入密碼便可。centos
mysql -u root -h localhost -p
