mysql复制架构的详细配置和设置过程如下：
Master节点配置与初始化：
Master节点的配置文件如下：
[client] port = 3306 socket = /tmp/master-mysql.sock[mysql] no-auto-rehash
[mysqld] sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES user = mysql port = 3306 socket = /tmp/master-mysql.sock server-id=1 port=3306 datadir=/data1/mysql/master/data log_error=/data1/mysql/master/log/master.log pid_file=/data1/mysql/master/data/mysql.pid server_id=101 gtid_mode=on enforce_gtid_consistency=on log_bin=master-binlog log-slave-updates=1 binlog_format=row skip_slave_start=1 max_connect_errors=1000
Master节点的数据库初始化命令：
mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data1/mysql/master/data
Master节点数据库启动命令：
nohup mysqld_safe --defaults-file=/data1/my-master.cnf > master.log 2>&1 &
Slave节点配置与初始化：
Slave节点的配置文件如下：
[mysqld] sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES user = mysql port = 3307 socket = /tmp/slave-mysql.sock datadir=/data1/mysql/slave/data log-error = /data1/mysql/slave/log/slave.log pid-file = /data1/mysql/slave/data/slave.pid max_connect_errors=1000 gtid_mode=on enforce_gtid_consistency=on server_id=102 log-bin=slave-binlog log-slave-updates=1 binlog_format=row skip_slave_start=1
Slave数据库初始化命令：
mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data1/mysql/slave/data
Slave节点数据库启动命令：
nohup mysqld_safe --defaults-file=/data1/my-slave.cnf > slave.log 2>&1 &
主从节点创建超级用户：
在Master节点上创建超级用户：
[perrynzhou@debian /data1]$ mysql -uroot -P 3306 -S /tmp/master-mysql.sock mysql> create user 'admin'@'%' identified by 'admin'; mysql> grant all privileges on . to 'admin'@'%'; mysql> flush privileges;
GTID复制配置：
在主节点上创建复制用户：
[perrynzhou@debian /data1]$ mysql -uroot -P 3306 -S /tmp/master-mysql.sock mysql> create user 'repl'@'%' identified by 'repl'; mysql> grant replication slave,replication client on . to 'repl'@'%'; mysql> flush privileges;
在Slave节点上验证Master节点的复制用户：
mysql -urepl -prepl -h127.0.0.1 -P 3306
在Slave节点上配置主从复制：
[perrynzhou@debian /data1]$ mysql -uroot -S /tmp/slave-mysql.sock -P 3307 -p mysql> change master to master_host='127.0.0.1', master_user='repl', master_password='repl', master_port=3306, master_auto_position=1; mysql> start slave;
查看Slave节点的复制状态：
