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 |
