(一)mysql 5.7.13 安装配置方法
1、mysql-5.7.12-winx64.zip下载
官方下载地址:http://dev.mysql.com/downloads/mysql/
2.解压到C:\job\mysql-5.7.12-winx64
3.在C:\job\mysql-5.7.12-winx64下新建my.ini配置文件
内容如下:

####################配置文件开始###################

####################配置文件结束###################

重点是以下配置,其中datadir的目录名称必须是:C:\job\mysql-5.7.12-winx64/data/,加上skip-grant-tables,使root不输密码,登陆

4.在windows系统环境变量path,加入如下内容
C:\job\mysql-5.7.12-winx64\bin;(注意加分号)

5.将mysql注册为windows系统服务
具体操作是在命令行中执行以下命令(需要以管理员身份运行命令行):
cd C:\Windows\System32
以管理员身份运行cmd.exe
需要切换到bin目录,否则,会将服务目录指定为C:\job\mysql-5.7.12-winx64\bin
增加服务命令:mysqld install MySQL –defaults-file=”C:\job\mysql-5.7.12-winx64\my.ini”
移除服务命令为:mysqld remove

6.第5步成功后,初始化data目录
C:\job\mysql-5.7.12-winx64\bin>mysqld –initialize
此步骤非常重要,未初始化,可能会导致mysql服务无法启动(坑一)

7.打开系统服务管理
可以看到mysql系统服务
在命令行启动mysql命令为: net start mysql
关闭mysql命令为:net stop mysql

8、修改root密码
命令行执行:

mysql –uroot

mysql>show databases;

mysql>use mysql;
mysql> update mysql.user set authentication_string=password('12345') where user='root' and Host = 'localhost';

mysql> alter user 'root'@'localhost' identified by '12345';

mysql> FLUSH PRIVILEGES;

mysql> QUIT

坑二:新版的mysql数据库下的user表中已经没有Password字段了,而是将加密后的用户密码存储于authentication_string字段

9.远程登陆配置
允许root用户在任何地方进行远程登录,并具有所有库任何操作权限,具体操作如下:
1)在本机先使用root用户登录mysql:
命令行执行:mysql -u root -p
输入密码(第7步中设置的密码):12345
2)进行授权操作:

mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '12345' WITH GRANT OPTION;

重载授权表:

mysql>FLUSH PRIVILEGES;
退出mysql:quit
