1. Unzip the downloaded mysql installation package to get the following directory structure
H:\Workspaces\mysql-5.7.12-winx64
2. Set environment variables
MYSQL_HOME=H:\Workspaces\mysql-5.7.12-winx64
PATH=%MYSQL_HOME%\bin
3. Modify \my-default.ini in the mysql root directory
basedir = H:\Workspaces\mysql-5.7.12-winx64
datadir = H:\Workspaces\mysql-5.7.12-winx64\data
port = 3306
2. Enter the MySQL bin folder and install the MySQL service
MySQL install installation service
Order:
bin>mysqld install #Install MySQL service
3. Initialize the MySQL data directory.
Initialize the MySQL data directory
Order:
\bin>mysqld --initialize
4. Start mysql
bin>net start mysql
5. Use mysql to log in at this time
bin>mysql -u root
会报错：ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
Because root has an initialization password.
6. Modify the root password of mysql
bin>net stop mysql bin>mysqld --skip-grant-tables #Start in safe mode
At this time, the window does not understand, you need to open another window
cmd...>bin>mysql
Log in to mysql at this time
mysql>
7. Modify the root password
In mysql5.7, there is no password field in the user table, it becomes authentication_string
mysql>show databases;
mysql>use mysql;
mysql> update mysql.user set authentication_string=password('root') where user='root' and Host = 'localhost';
mysql> FLUSH PRIVILEGES;
mysql> QUIT
8. Allow the root user to log in remotely from anywhere and have any operation permissions for all libraries. The specific operations are as follows:
1) Log in to mysql using the root user on this machine:
Command line execution: mysql -u root -p root
2) Perform an authorization operation:
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'youpassword' WITH GRANT OPTION;
Reload the authorization table:
mysql>FLUSH PRIVILEGES;
quit mysql: quit
