2. Start logging in to mysql for related operations
/usr/local/mysql-3306> bin/mysql -uroot -p
Note that when bin/mysqld is initialized, a temporary password is given in the last prompt of the command line, and you can log in after entering it.
After logging in to mysql, you are required to change the password immediately, otherwise you cannot perform any operations. Execute the following command to change the password of 'root'@'localhost':
mysql> SET PASSWORD = PASSWORD('your new password');
mysql> ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
mysql> flush privileges;
In order to be able to log in remotely, add a 'root'@'%' account:
mysql> grant all privileges on *.* to 'root'@'%' identified by 'your new password' with grant option;
3. According to the above method, continue to decompress and install mysql-5.7.14-linux-glibc2.5-x86_64.tar.gz, and configure it as 3307, 3308, 3309 ports, you can install multiple mysql.
