window 下mysql5.7.12安装报错记录

1）官网下载mysql5.7.17解压

my-default.ini文件命名为my.ini：

# For advice on how to change settings please see

# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the

[mysqld]

# Remove leading # and set to the amount of RAM for the most important data

# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.

# innodb_buffer_pool_size = 128M

# Remove leading # to turn on a very important data integrity option: logging

# changes to the binary log between backups.

# log_bin

# These are commonly set, remove the # and set as required.

[mysql.server]

default_character_set = utf8

[mysqld_safe]

default_character_set = utf8

[client]

-----------------------------------------------------------------------------------------------

2）安装服务：

mysqld -install mysql

net start mysql

发现错误1067
Can't open and lock privilege tables: Table 'mysql.user' doesn't exist

直接用命令初始化：

指定配置文件：mysqld --install mysql --defaults-file="D:\mysql-5.7.12\my.ini

初始化：mysqld --defaults-file=D:\mysql-5.7.12\my.ini --initialize 

3）修改密码：

mysqld --skip-grant-tables 启动mysql

打开新的cmd：mysql -u root mysql

mysql> UPDATE user SET password=PASSWORD('root') WHERE user='root';
4）远程登陆mysql
例如，你想myuser使用mypassword从任何主机连接到mysql服务器的话。

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

FLUSH   PRIVILEGES;

如果你想允许用户myuser从ip为192.168.1.6的主机连接到mysql服务器，并使用mypassword作为密码

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

FLUSH   PRIVILEGES;

OK
