mysql基于GTID复制步骤

1. 在主DB服务器上建立复制账号

CREATE USER 'repl' @' ip段‘ indentified by 'PassWord';
GRANT REPLICATION SLAVE ON *.* TO 'repl'@ 'IP段';

2. 配置主数据库服务器 (/etc/mysql/mysql.conf.d/mysql.cnf)

bin_log = /var/log/mysql/mysql-bin
server_log = 100
gtid_mode = on
enforce-gtid-consistency = on  # 强制gtid一致性
log-slave-updates = on # 5.7以前版本必须配置此参数

3. 配置从数据库服务器

server_id = 101
relay_log = /var/log/mysql/relay_log
gtid_mode = on
enforce-gtid-consistency = on

log-salve-updates = on
read_only = on
master_info_repository = TABLE
relay_log_info_repository = TABLE

4. 初始化从服务器数据,在主mysql服务器导出数据

mysqldump --master-data=2 --single-transaction --triggers --routines --all-databases -uroot -p > all.sql

在从服务器上导入数据

mysql -uroot -p < all.sql

5. 启动基于GTID的复制 在从服务器mysql里输入以下命令

CHANGE MASTER TO MASTER_HOST = 'master_host_Ip', MASTER_USER= 'repl', MASTER_PASSWORD= 'Password', MASTER_AUTO_POSITION = 1;
start slave;
