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
