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.
