-------配置Master-Slave(基于位点)
环境介绍：
服务器：RHEL 6.8
Master_Port：3306
Slave_Port：3307
Mysql：5.7.19-log
Xtrabackup：xtrabackup version 2.4.15
Master部分：
1.Master设置复制用户，授权
mysql>grant replication slave on *.* to 'repl'@'%' identified by '111111' ;
Query OK, 0 rows affected, 1 warning (0.37 sec)
2.Master设置参数，开启binlog
log-bin=/u01/mysql/log/mysql-bin
server-id=10241
log_slave_updates=1
#binlog-do-db=test
#binlog-do-db=testrecovery
(binlog-do-db可以指定哪些库启用binlog日志记录，本次实验我没用这个)
3.使用Xtrabackup备份
[root@rhel6 data]# xtrabackup --defaults-file=/etc/my.cnf --backup -uroot -pxxx --target-dir=/u01/mysqlbackup/all-20190731bak
4.prepare备份集
(prepare只需要指定备份集路径即可，网上很多例子中的账号、密码、参数文件等参数理论上都无需指定)
[root@rhel6 data]#xtrabackup --prepare --target-dir=/u01/mysqlbackup/all-20190731bak/
Slave部分：
1.停服务、备份data、还原备份集
[root@rhel6 data]#mysqladmin -uroot -xxx --socket=/tmp/mysql3307.sock shutdown
[root@rhel6 data]#mv data data_bak
[root@rhel6 data]#cp -R /u01/mysqlbackup/all-20190731bak data
[root@rhel6 data]#chown -R mysql:mysql data/
2.修改参数文件，起服务
server-id=10242
log-bin=/u01/mysql3307/log/mysql3307-bin
#replicate-do-db=test
#replicate-do-db=testrecovery
log_slave_updates=1
(replicate-do-db可以指定哪些库启用binlog复制，本次实验我也没用这个)
[root@rhel6 data]#mysqld_safe --defaults-file=/etc/my3307.cnf &
3.从xtrabackup_binlog_info中获取master_log_file和master_pos
[root@rhel6 all-20190732bak]# cat xtrabackup_binlog_info
mysql-bin.000007 1372 5f95521a-b073-11e9-9591-000c296ee978:1-7,
7842c967-0958-11e9-9f6c-000c296ee978:1-36,
eb495b42-b06a-11e9-af85-000c296ee978:1-3,
fad44c35-affe-11e9-b2fc-000c296ee978:1-2
4. 配置复制相关信息
[root@rhel6 ~]# mysql -uroot -pxxx --host=127.0.0.1 --port=3307

fad44c35-affe-11e9-b2fc-000c296ee978:1-2
4.配置复制相关信息
1)查看slave的Executed_Gtid_Set，如果不为空的话，需要执行reset master进行清理
