centos7下yum安裝mysql

CentOS 7的yum源中貌似沒有正常安裝mysql時的mysql-sever文件，需要去官網上下載

# 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
成功安裝之後重啓mysql服務

# service mysqld restart
初次安裝 mysql 是 root 賬戶是沒有密碼的
設置密碼的方法

# mysql -uroot
mysql> set password for ‘root’@‘localhost’ = password('mypasswd');
mysql> exit
搞定！
