1.master配置

server-id=1
log-bin=mysql-bin
binlog-do-db=testdata
binlog-ignore-db=mysql

2.master增加用戶

 grant replication slave on *.* to ‘test‘ @‘192.168.176.%‘ identified by ‘123456‘;

3.從數據庫檢測是否可以遠程連接主數據庫

筆記：防火墻3306端口開通 iptables -I INPUT -s 0/0 -p tcp --dport 3306 -j ACCEPT 查看iptables -L -n|grep 3306

4.從數據庫配置

server-id=2
expire_logs_days=10
max_binlog_size=100M
relay-log=slave-relay-bin
relay-log-index=salve-relay-bin.index

5.登錄從數據庫

1.reset slave；

2.change master to master_host=‘192.168.176.3‘,master_port=3306,master_user=‘test‘,master_password=‘123456‘,master_log_file=‘mysql-bin.000003‘,master_log_pos=120;

,master_log_file與master_log_pos 在主數據庫 show master status；中查看

3.start slave；

筆記，不同數據庫復制庫表 ：mysqldump testdata -uroot -proot --add-drop-table | mysql -h 192.168.176.4 testdata -u root -proot
前提，1.目標數據庫建好庫 CREATE DATABASE `wordpress` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

2.授權遠程連接GRANT ALL PRIVILEGES ON *.* TO root@"%" IDENTIFIED BY "root";

mysql重啟 service mysqld restart 配置文件 :/etc/my.cnf
