GTID复制环境搭建

基本环境

master slave

mysql版本 mysql-5.7.14x86_64  mysql-5.7.14x86_64

ip 192.168.0.100 192.168.0.101

port 3306 3306

搭建注意事项

主库配置

#master

gtid-mode=on

enforce-gtid-consistency=1

binlog_format=row

server-id=3306100

log-bin=/data/mysql/mysql3306/log/mysql-bin

binlog_cache_size=4M

skip_slave_start=1

主库创建复制账号

create user ‘repl‘@‘192.168.0.%‘ identified by ‘repl4slave‘;

grant replication slave on *.* to ‘repl‘@‘192.168.0.%‘;

从库配置

#master

gtid-mode=on

enforce-gtid-consistency=1

binlog_format=row

server-id=3306101

log-bin=/data/mysql/mysql3306/log/mysql-bin

binlog_cache_size=4M

skip_slave_start=1

查看复制：show slave status\G;

开始复制：start slave

停止复制: stop salve

mysql全库备份

mysqldump -uroot -p  --single-transaction --master-data=2 -A > liangxiaoming_20161224.sql

参数查看master

show global variables like "%server%"

show global variables like "%gtid%"

show global variables like "%log_bin%"

show master status;

从库恢复数据

mysql -u root -p <liangxiaoming_20161224.sql

如果恢复不了

show global variables like "%gtid%"

reset master ;

show global variables like "%gtid%"

配置从服务器Slave：

   mysql>change master to master_host=‘192.168.0.100‘,master_port=3306,master_user=‘repl‘,master_password=‘repl4slave‘,master_auto_position=1; 

   Mysql>start slave;    //启动从服务器复制功能
