关于mysql:MySQL配置主从

1. 环境筹备

   • 192.168.32.130 – 主库
   • 192.168.32.131 – 从库
2. 主库 my.cnf 减少以下配置

log-bin=mysql-bin
server-id=123

2. 从库 my.cnf 减少以下配置

server-id=124

3. 主库上执行 SQL

CREATE USER 'repl'@'192.168.32.%' IDENTIFIED BY '123456';
GRANT REPLICATION SLAVE ON *.* TO 'repl'@'192.168.32.%';
SHOW MASTER STATUS;

4. 从库上执行 SQL

CHANG MASTER TO MASTER_HOST='192.168.128.130', MASTER_USER='repl', MASTER_PASSWORD='123456', MASTER_LOG_FILE='mysql-bin.000002', MASTER_LOG_POS=10368;
START SLAVE;
SHOW SLAVE STATUS;
