Mysql 5.7 基于GTID搭建主从复制 一、搭建过程 1.1 准备三个mysql实例 mysqld --initialize-insecure --use
mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/mysql/3307/data/
mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/mysql/3308/data/
mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/mysql/3309/data/mysql -uroot -p123 -e "select @@server_id"
mysql -uroot -p123 -e "select @@server_uuid"mysql -uroot -p123 -e "select @@gtid_mode"
mysql -uroot -p123 -e "select @@server_gtid"
vi 330{7..9}/my.cnf
gtid_mode=ON
enforce_gtid_consistency=ON
log_slave_updates=ONmysql -uroot -p123 -e "select @@log_bin"mysqldump -uroot -p123 -h 192.168.84.30 -P 3307 > /tmp/full.sqlmysql> source /tmp/full.sql grant replication slave on *.* to repl@'192.168.84.30' identified by '123'; 帮助：
mysql> help change master to
......
找到配置模板：
CHANGE MASTER TO
MASTER_HOST='master2.example.com',
MASTER_USER='replication',
MASTER_PASSWord='password',
MASTER_PORT=3306,
MASTER_LOG_FILE='master2-bin.001',
MASTER_LOG_POS=4,
MASTER_CONNECT_RETRY=10;
3308，3309使用如下配置：
CHANGE MASTER TO
MASTER_HOST='192.168.84.30',
MASTER_USER='repl',
MASTER_PASSWORD='123',
MASTER_PORT=3307,
master_auto_position=1;
开始配置3308
mysql> CHANGE MASTER TO
-> MASTER_HOST='192.168.84.30',
-> MASTER_USER='repl',
-> MASTER_PASSWORD='123',
-> MASTER_PORT=3307,
-> master_auto_position=1;
Query OK, 0 rows affected, 2 warnings (0.00 sec)
开始配置3309
mysql> CHANGE MASTER TO
-> MASTER_HOST='192.168.84.30',
-> MASTER_USER='repl',
-> MASTER_PASSWORD='123',
-> MASTER_PORT=3307,
-> master_auto_position=1;
Query OK, 0 rows affected, 2 warnings (0.00 sec)--结束END--
