一、配置mysql gtid下主从复制
master库192.195.1.131操作：
[root@VM_82_178_centos ~]# mysql -e "grant replication slave on *.* to rep@'192.195.1.233' identified by '23458&34%'; flush privileges;"
[root@VM_82_178_centos ~]# mysqldump -uroot -p'jianwuweirootmysql' -B -A -F --master-data=2 --single-transaction --events|gzip >/opt/test_$(date +%F).sql.gz
mysqldump: [Warning] Using a password on the command line interface can be insecure.
Warning: A partial dump from a server that has GTIDs will by default include the GTIDs of all transactions, even those that changed suppressed parts of the database. If you don't want to restore GTIDs, pass --set-gtid-purged=OFF. To make a complete dump, pass --all-databases --triggers --routines --events. slave库192.195.1.233操作：

同步报错：
Last_Errno: 1007
Last_Error: Coordinator stopped because there were error(s) in the worker(s). The most recent failure being: Worker 1 failed executing transaction 'df8f817c-f215-11e8-83e4-525400950067:5' at master log mysql-bin.000004, end_log_pos 359. See error log and/or performance_schema.replication_applier_status_by_worker table for more details about this failure or others, if any.slave库报错1007，是slave库上已经存在库名，然而master库上又创建相同的库名，从而导致的报错。
分析解决过程：
主库查看binlog文件mysql-bin.000004内容，发现是一开始配置主从库时，主从server_id相同导致的复制失败，于是修改主库的server_id,记录到mysql-bin.000004文件中(从提交的事物的Gtid可以看出来).
