主從節點更改 root@‘localhost‘ 密碼和創建復制賬號
set sql_log_bin=0;
alter user root@‘localhost‘ identified by ‘MySQL5.7‘;
create user root@‘%‘ identified by ‘MySQL5.7‘;
grant all on *.* to root@‘%‘;
flush privileges;
set sql_log_bin=1;將主節點的數據傳到從節點
mysqldump -S /usr/local/mysql/data/mysql.sock -u root -pMySQL5.7 --all-databases --triggers --routines --events --single-transaction --quick | mysql -h 192.168.1.226 -P 3366 -u root -pMySQL5.7
將從服務器指定到主服務器
change master to master_host=‘192.168.1.225‘,master_port=3366,master_user=‘root‘,master_password=‘MySQL5.7‘,master_auto_position=1,MASTER_DELAY=120;
start slave;
show slave status\G在主服務器使用以下腳本插入數據
shell> cat mysql.sh #!/bin/bash while true do mysql -S /usr/local/mysql/data/mysql.sock -u root -pMySQL5.7 -e "insert into testdb.dt values(now())"; sleep 1 done
結果：從服務器的數據延時120秒生成，主服務器停機後2分鐘，從服務器持續更新2分鐘
