Centos7 安装Mysql5.7

1 下载:   

[root@localhost ~]# wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm

2 安装:   

[root@localhost ~]# yum -y install mysql57-community-release-el7-10.noarch.rpm

[root@localhost ~]# yum -y install mysql-community-server

3 启动:    

[root@localhost ~]# systemctl start  mysqld.service

  查看状态:   

[root@localhost ~]# systemctl status mysqld.service

  

4 修改密码: 

[root@localhost ~]# grep "password" /var/log/mysqld.log

[root@localhost ~]# mysql -uroot -p

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'new password';

注意：这里如果要使用简单密码，需先输入下面两句命令，再修改密码才可以：

mysql> set global validate_password_policy=0;
mysql> set global validate_password_length=1;

由于安装yum repository,导致操作yum会自动更新，需执行下面命令：

[root@localhost ~]# yum -y remove mysql57-community-release-el7-10.noarch
