1. Launch instances 3306 and 3307

2. Check the master library configuration

[root@client 3306]# egrep "log-bin|server|sock" my.cnf

socket = /data/3306/mysql.sock

socket = /application/mysql-5.5.32/tmp/mysql.sock

#socket = /data/3306/mysql.sock

log-bin = /data/3306/mysql-bin

server-id = 1

Check if the configuration works

[root@client 3306]# mysql -S /application/mysql-5.5.32/tmp/mysql.sock -e "show variables like 'log_bin'"

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

| Variable_name | Value |

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

| log_bin | ON |

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

3. Check the slave library configuration

[root@client 3307]# egrep "log-bin|server|sock" my.cnf

socket = /data/3306/mysql.sock

socket = /application/mysql-5.5.32/tmp/mysql.sock

#socket = /data/3306/mysql.sock

log-bin = /data/3306/mysql-bin

server-id = 1

4. Main library configuration

mysql>grant replication slave on *.* to 'rep'@'%' identified by 'oldboy123'

mysql>flush privileges

mysql>flush table with read lock

mysql> show master status;

mysqldump -S /application/mysql-5.5.32/tmp/mysql.sock -A -B --events --master-data=2 > /tmp/rep1.sql

mysql>unlock tables

5. Restore slave library

mysql -S /data/3307/mysql.sock

< /tmp/rep1.sql cat |mysql -S /data/3307/mysql.sock start slave; mysql>

show slave status \G;
