replication简单完成配置 m-s(主从)

replication简单几步完成配置 m-s

1.在master上赋权

grant replication slave on *.* on ‘sync‘@‘slaveip‘ identied by ‘password‘;

flush privileges;

2.master配置

[mysqld]

log-bin

binlog-format=row   --提供性能

sync-binlog=1       --官方建议打开

server-id=1

3.制作master完整备份

innobackupex --user=dba --password=beifen /var/lib/backup/

innobackupex --use-memory=500m --apply-log /var/lib/backup/2015-06-13_10-38-21/

4.拷贝全备到slave并恢复备份

scp /var/lib/backup/2015-06-13_10-38-21/ slaveip:/var/lib/backup/

cd /var/lib/backup/2015-06-13_10-38-21/

service mysql stop

mv * /var/lib/mysql

chown -R mysql.mysql /var/lib/mysql

5.slave配置

[mysqld]

server-id=2

6.查看并记录二进制日志中的position id

cd /var/lib/mysql

cat xtrabackup_binlog_info

7.配置slave replication

在slave

change master to

master_host=‘master_ip‘,

master_user=‘dba‘,

master_password=‘beifen‘,

master_log_file=‘host2-bin.0000001‘,

master_log_pos=120;

8.启动replication，并检查结果

在slave

start slave

show slave status \G;
