2018.4.26 。Mac安装Mysql

在浏览器输入网址dev.mysql.com/downloads/mysql/

1.下载YUM库

shell > wget http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm

2.安装YUM库

shell > yum localinstall -y mysql57-community-release-el7-7.noarch.rpm

3.安装数据库

shell > yum install -y mysql-community-server

4.启动MySQL服务

shell > systemctl start mysqld.service

5.默认空密码

shell > mysql -uroot -p

6.重置root密码后重启mysql服务

shell > update mysql.user set authentication_string=password("yourpassword") where user="root" and Host="localhost";

shell > flush privileges;

shell > quit;

shell > systemctl restart mysqld;

如果手贱或者不知道啥原因出现如下问题：

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

请修改my.cnf,添加skip-grant-tables和skip-networking：

shell > vi /etc/my.cnf

[mysqld]

skip-grant-tables

skip-networking

重启mysql，然后重复以上修改密码步骤即可，记得修改完后，去掉my.cnf添加的两行。
