MySQL Master-slave replication

Master-slave Replication steps

1: Open the main library binlog function

See if 3306 is turned on

grep log-bin/etc/my.cnf

See if it's not the same

2: Make sure the Server-id is different

grep server-id/etc/my.cnf

grep server-id/data/3307/my.cnf

3: User rep for Master library authorized replication

Grant Replication Slave on * * to [e-mail protected] ' 192.168.1.102 ' identified by ' 2017 ';

See if authorization is successful

4: Lock table, view Binlog location point

Lock table to ensure database consistency

Flush table with read lock;

Show master status; Look at the backup point

Show master status;

+------------------+----------+--------------+------------------+

| File | Position | binlog_do_db | binlog_ignore_db |

+------------------+----------+--------------+------------------+

|      mysql-bin.000053 |              339 |                  | |

+------------------+----------+--------------+------------------+

5. New open window export fully prepared

Mysqldump-uroot-p2017-a-B--events-s/tmp/mysql.sock|gzip >/home/chaofu/rep_bak_$ (date +%F). sql.gz

6:unlock Table Release Lock

From library:

1: Make sure the Server-id is different

2: Restore the data from the main library to the library

Gzip-d rep_bak.sql.gz

Mysql-uroot-p-s/data/3307/mysql.sock

3: Find location point, configure Master.info

Change MASTER to

Master_host= ' 192.168.1.102 ',

master_port=3306,

Master_user= ' rep ',

master_password= ' 2017 ',

Master_log_file= ' mysql-bin.000053 ',

master_log_pos=339;

Find/data/3307/data-type-f-name "*.info"

4: Turn on the backup switch

Start slave;

show slave status \g;

Two threads from a library

5: Test
