使用Xtarbakcup实现mysql主从同步详细步骤

[root@backup ~]# cat /etc/my.cnf|egrep "data|server"
#注意：主从状态会跟进serverID去判定，所有主的必定最小

innobackupex --user=root --password=mysqlpassword --socket=/data/mysqldata/mysql.sock  --defaults-file=/etc/my.cnf /tmp/

 需要操作：同步应用日志

     innobackupex --apply-log /data/backup/innobackupex/2014-07-31_11-20-44

    GRANT REPLICATION SLAVE ON *.* TO repl@'192.168.106.%' IDENTIFIED BY 'password';

scp -r ./2014-07-31_11-20-44 192.168.223.133:/data/backup
#先备份数据目录下的数据，方便恢复

[root@ds1 tmp]# cat /tmp/2017-12-29_12-33-01/xtrabackup_binlog_info 
mysql-bin.000460    82773878

innobackupex --user=root --password=password --apply-log  /tmp/2017-12-27_14-36-43
innobackupex --user=root --password=password --socket=/tmp/mysql.sock --defaults-file=/etc/my.cnf --copy-back /tmp/

chown -R mysql.mysql var/  
##var是mysql data目录

[root@backup mysql]# /etc/init.d/mysql start
Starting MySQL..                                           [  OK  ]

查看上面binlog位置
change master to master_host='10.27.82.*', master_user='repl', master_password='replpassword',master_port=3306,master_log_file='mysql-bin.000460',master_log_pos=82773878;

mysql> start slave;
Query OK, 0 rows affected (0.00 sec)
