怎樣進行MYSQL主從復制的搭建

log-bin=mysql-bin

# binary logging format - mixed recommended

binlog_format=mixed         //主從復制模式,混合模式（MBR）默認的

binlog_cache_size=4M      //設置binlog緩存大小

max_binlog_size=300M    //設置binlog文件最大體積

replicate_do_db=retail

mysql> GRANT REPLICATION SLAVE ON *.* TO 'server01'@'%' IDENTIFIED BY 'server01';

mysql>FLUSH TABLES WITH READ LOCK;   //先鎖定數(shù)據(jù)庫，等恢復完成后，再解鎖

Query OK, 0 rows affected (0.00 sec)

mysql> reset master;

Query OK, 0 rows affected (0.00 sec)

不要退出這個終端，否則這個鎖就失效了；在不退出終端的情況，再開一個終端直接打包壓縮數(shù)據(jù)文件或使用mysqldump工具來導出數(shù)據(jù)。

# mysqldump -uroot -p  retail > /tmp/retail.sql

mysql> show master status;       //查看主服務器binlog和Postion

Binlog_Ignore_DB:

1 row in set (0.00 sec)

#binlog_format=mixed

# required unique id between 1 and 2^32 - 1

# defaults to 1 if master-host is not set

# but will not function as a master if omitted

server-id= 3       //跟master區(qū)分開來

read_only=1

replicate_do_db= retail

創(chuàng)建retail數(shù)據(jù)

mysql> create database retail

進行數(shù)據(jù)的導入

mysql>  SOURCE /tmp/retail.sql

mysql> CHANGE MASTER TO MASTER_HOST='192.168.47.149',MASTER_USER='server',MASTER_PASSWORD='server', MASTER_LOG_FILE='mysql-bin.000001',MASTER_LOG_POS=2424;

mysql> SLAVE START   //啟動SLAVE服務

mysql> SHOW SLAVE STATUS\G;  //檢查slave的連接情況

mysql> SHOW SLAVE STATUS\G
