1、启动实例3306和3307
2、检查主库配置[root@client 3306]# egrep "log-bin|server|sock" my.cnfsocket = /data/3306/mysql.socksocket = /application/mysql-5.5.32/tmp/mysql.sock#socket = /data/3306/mysql.socklog-bin = /data/3306/mysql-binserver-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.cnfsocket = /data/3306/mysql.socksocket = /application/mysql-5.5.32/tmp/mysql.sock#socket = /data/3306/mysql.socklog-bin = /data/3306/mysql-binserver-id = 14、主库配置mysql>grant replication slave on *.* to 'rep'@'%' identified by 'oldboy123'mysql>flush privilegesmysql>flush table with read lockmysql> show master status;mysqldump -S /application/mysql-5.5.32/tmp/mysql.sock -A -B --events --master-data=2 > /tmp/rep1.sqlmysql>unlock tables5、恢复从库mysql -S /data/3307/mysql.sock < /tmp/rep1.sqlcat |mysql -S /data/3307/mysql.sock << EOFCHANGE MASTER TOMASTER_HOST='192.168.12.200',MASTER_PORT=3306,-------------------------------注意不要用引号MASTER_USER='rep',MASTER_PASSWORD='oldboy123',MASTER_LOG_FILE='mysql-bin.000016',MASTER_LOG_POS=421;--------------------------注意不要用引号EOFmysql> start slave;mysql> show slave status \G;*************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: 192.168.12.200 Master_User: rep Master_Port: 3306 Connect_Retry: 60 Master_Log_File: mysql-bin.000016 Read_Master_Log_Pos: 421 Relay_Log_File: relay-bin.000002 Relay_Log_Pos: 253 Relay_Master_Log_File: mysql-bin.000016 Slave_IO_Running: Yes Slave_SQL_Running: Yes Replicate_Do_DB: Replicate_Ignore_DB: mysql Replicate_Do_Table: Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 0 Last_Error: Skip_Counter: 0 Exec_Master_Log_Pos: 421 Relay_Log_Space: 403 Until_Condition: None Until_Log_File: Until_Log_Pos: 0 Master_SSL_Allowed: No Master_SSL_CA_File: Master_SSL_CA_Path: Master_SSL_Cert: Master_SSL_Cipher: Master_SSL_Key: Seconds_Behind_Master: 0Master_SSL_Verify_Server_Cert: No Last_IO_Errno: 0 Last_IO_Error: Last_SQL_Errno: 0 Last_SQL_Error: Replicate_Ignore_Server_Ids: Master_Server_Id: 1
