1、启动实例3306和3307

2、检查主库配置
[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

查看配置是否生效
[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、检查从库配置
[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、主库配置

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、恢复从库
mysql  -S  /data/3307/mysql.sock < /tmp/rep1.sql

cat |mysql  -S /data/3307/mysql.sock << EOF
CHANGE MASTER TO
MASTER_HOST='192.168.12.200',

MASTER_USER='rep',
MASTER_PASSWORD='oldboy123',
MASTER_LOG_FILE='mysql-bin.000016',
MASTER_LOG_POS=421;--------------------------注意不要用引号
EOF


mysql> start slave;

mysql> show  slave  status \G;
