MYSQL主從復(fù)制的搭建方式

log-bin=mysql-bin

# binary logging format - mixed recommended

binlog_format=mixed //主從復(fù)制模式,混合模式（MBR）默認(rèn)的

binlog_cache_size=4M //設(shè)置binlog緩存大小

max_binlog_size=300M //設(shè)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(fù)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(gè)終端，否則這個(gè)鎖就失效了；在不退出終端的情況，再開一個(gè)終端直接打包壓縮數(shù)據(jù)文件或使用mysqldump工具來導(dǎo)出數(shù)據(jù)。

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

mysql> show master status; //查看主服務(wù)器binlog和Postion
