As I had just finished the above steps, the computer could not operate remotely at this time, the terminal was lost, and the password was naturally gone, so I deleted the kong empty var/log/mysqld.log log file to enter the safe mode.

Cd / usr/local/mysql/bin

. / mysqld_safe-- skip-grant-tables & in this mode, after MySQL logs in

Perform the initialization of step 5 here and find the password

Grep "temporary password" / var/log/mysqld.log

Change the password after restarting MySQL and entering normal mode.

Mysql > set password for root@localhost=password ('123456')

Mysql > show variables like 'validate_password%'; to see if the password is a complex policy

Empty set (0.00 sec)

Mysql > set password=password ('1234567')

Query OK, 0 rows affected, 1 warning (0.00 sec)

Mysql > flush privileges

Query OK, 0 rows affected (0.00 sec)

Master-slave replication based on binary system

Master: / etc/my.cnf add:

Server-id=1

Log-bin=mysql-bin

Show variables like 'log_bin'

Show master status

CREATE USER 'repl'@'%.mydomain.com' IDENTIFIED BY' slavepass'

GRANT REPLICATION SLAVE ON. TO 'repl'@'%.mydomain.com'

Slave:

Vim / etc/my.cnf is added as follows

Server-id = 2

Slop slave

Change master to

-> > master_host='192.168.137.2'

-> master_user='repl'

-> master_password='slavepass'

-> master_password='mysql-bin.0000002'

-> master_log_pos=319

Start slave

Show slave status

Check whether the io/sql thread is YES. If the status is wrong, look at the error log.
