关闭MySQL 5.6安装源

sudo yum-config-manager --disable mysql56-community

开启MySQL 5.7安装源

sudo yum-config-manager --enable mysql57-community
没有yum-config-manager命令可以安装yum install yum-utils.noarch工具 或者编辑/etc/yum.repos.d/mysql-community.repo文件enable项为1表示开启，为0表示关闭

VI命令修改python版本为2.7

vi /usr/libexec/urlgrabber-ext-down

yum -y install yum-utils

vi /bin/yum-config-manager

安装MySQL

yum -y install mysql-devel mysql-community-server

启动MySQL

systemctl start mysqld.service

安全配置MySQL

mysql_secure_installation

查看root用户初始密码：

[root@bogon ~]# cat /var/log/mysqld.log | grep 'password'
2017-05-16T02:49:27.631334Z 1 [Note] A temporary password is generated for root@localhost: ExQqWoo6Q1.u

mysql -uroot -p

设置密码

use mysql;

update user set password=password('密码') where user='root';

flush privileges;

一个错误：

mac mysql error You must reset your password using ALTER USER statement before executing this statement.

安装完mysql 之后，登陆以后，不管运行任何命令，总是提示这个

step 1: SET PASSWORD = PASSWORD('your new password');

step 2: ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;

step 3: flush privileges;

完成以上三步退出再登，使用新设置的密码就行了，以上除了红色的自己修改成新密码外，其他原样输入即可

 

远程连接设置 

把在所有数据库的所有表的所有权限赋值给位于所有IP地址的root用户。

mysql> grant all privileges on *.* to root@'%'identified by 'password';

如果是新用户而不是root，则要先新建用户

mysql>create user 'username'@'%' identified by 'password';  

重启MYSQL

systemctl restart mysqld.service

此时就可以进行远程连接了。
