centos 7 install mysql

CentOS 7的yum源中貌似没有正常安装MysqL时的MysqL-sever文件，需要去官网上下载 # wget http://dev.MysqL.com/get/MysqL-community-release-el7-5.noarch.rpm # rpm -ivh MysqL-community-release-el7-5.noarch.rpm # yum install MysqL-community-server 成功安装之后重启MysqL服务 # service MysqLd restart 初次安装MysqL是root账户是没有密码的 设置密码的方法 # MysqL -uroot MysqL> set password for ‘root’@‘localhost’ = password('mypasswd'); MysqL> exit 搞定！
