From the master copy mysql

Set up a master-slave replication

1. Prepare three hosts (this is a multi-instance)

3307 master
3308 salve1
3309 salve2

2. master node set

[ Mysqld ] 
log - bin = / Data / 3307 / MySQL - bin        - opening binary 
binlog_format = Row                   - log format 
Skip - name - Resolve                   - Close Domain Name 
Server - ID = 3307

3. salve node set

[mysqld]
server-id=
skip-name-resolve

4. Start multi-instance

5. maste create a replication account

grant replication slave on *.* to repl@'10.0.0.%' identified by '123456';
flush privileges;

6. Analysis of the situation master node

1) The new environment, do not need to back up the master data repository

Directly from the first binlog (mysql-bin.000001) of the head position (120)

2) the main library work for some time, call the shots from copy

① Backup main library

mysqldump -uroot -p123456 -S /data/3307/mysql.sock -A -R --triggers --master-data=2 --single-transaction >/tmp/full.sql

[root@db2 ~]# sed -n '22p' /tmp/full.sql
-- CHANGE MASTER TO MASTER_LOG_FILE='mysql-bin.000004', MASTER_LOG_POS=1036;

② to recover from the library

salve node operation

mysql -S /data/3308/mysql.sock 
mysql> set sql_log_bin=0;
mysql> source /tmp/full.sql

7 to open the main database synchronization from the library

help:

 help change master to

mysql -S /data/3308/mysql.sock

CHANGE MASTER TO
  MASTER_HOST='10.0.0.87',
  MASTER_USER='repl',
  MASTER_PASSWORD='123456',
  MASTER_PORT=3307,
  MASTER_LOG_FILE='mysql-bin.000004',
  MASTER_LOG_POS=1036;

From 8 to open the main

Open IO and SQL thread

salve node operation

mysql> start slave;

9 View from the main state

mysql> show slave status\G
