GTID复制配置过程：
(1) 清理环境
pkill mysqld
\rm -rf /data/mysql/data/*
\rm -rf /data/binlog/*
(2) 准备配置文件
主库db01：
cat > /data/my.cnf <<EOF
[mysqld]
basedir=/application/mysql
datadir=/data/mysql/data
socket=/tmp/mysql.sock
server_id=51
port=3306

autocommit=0
log_bin=/data/binlog/mysql-bin
binlog_format=row
gtid-mode=on
enforce-gtid-consistency=true
log-slave-updates=1
[mysql]
prompt=db01 [\d]>
EOF

binlog_format=row
gtid-mode=on
enforce-gtid-consistency=true
log-slave-updates=1
[mysql]
prompt=db03 [\d]>
EOF
(3) 初始化数据(3个节点多做)
mysqld --initialize-insecure --user=mysql --basedir=/application/mysql --datadir=/data/mysql/data
(4) 启动数据库
/etc/init.d/mysqld start
(5) 构建主从：
master:51
slave:52,53
51:
grant replication slave on . to repl@‘10.0.0.%’ identified by ‘123’;
52\53:
change master to
master_host=‘10.0.0.51’,
master_user=‘repl’,
master_password=‘123’ ,
MASTER_AUTO_POSITION=1;
