MySQL Replication 配置
1.Master配置
打开MySQL配置文件，
[mysqld]
log-bin=mysql-bin //启用二进制日志文件，MySQL的服务器之间数据配置依赖此文件
server-id=1 //如果为0，则会拒绝Slave的连接
innodb_flush_log_at_trx_commit=1
sync_binlog=1 //以上两行是为了保证数据的一致性和持久性
#skip-networking //如果启用，这Master和Slave之间不能通信
2.Slave配置
[mysqld]
server-id=2
3.在Master
mysql>FLUSH TABLES WITH READ LOCK;//给所有表加只读锁
mysql>SHOW MASTER STATUS;
第4步中的MASTER_LOG_FILE , MASTER_LOG_POS 从此命令显示的结果中获取
4.Slave
mysql>stop slave;
mysql> CHANGE MASTER TO
> MASTER_HOST = 'host_name', //Master服务器的域名或IP
> MASTER_USER = 'user_name', //Master数据库的用户名
> MASTER_PASSWORD = 'password', //Master数据库的密码
> MASTER_PORT = port_num, //Master数据库的端口
> MASTER_CONNECT_RETRY = interval,
> MASTER_HEARTBEAT_PERIOD = interval,
> MASTER_LOG_FILE = 'master_log_name',
> MASTER_LOG_POS = master_log_pos,
> RELAY_LOG_FILE = 'relay_log_name',
> RELAY_LOG_POS = relay_log_pos,
> MASTER_SSL = {0|1},
> MASTER_SSL_CA = 'ca_file_name',
> MASTER_SSL_CAPATH = 'ca_directory_name',
> MASTER_SSL_CERT = 'cert_file_name',
> MASTER_SSL_KEY = 'key_file_name',
> MASTER_SSL_CIPHER = 'cipher_list',
> MASTER_SSL_VERIFY_SERVER_CERT = {0|1},
> IGNORE_SERVER_IDS = (server_id_list);
mysql>start slave;
