Master主服務器IP:192.168.1.202
Slave從服務器IP:192.168.1.203
Master配置
設置server-id、啓用bin-log二進制日誌
vim /etc/my.cnf
[mysqld]
log_bin = master_bin
server-id = 1
innodb_file_per_table = ON
skip_name_resolve = ON
添加slave賬戶授權訪問
mysql> grant replication slave,replication client on *.* to 'repluser'@'192.168.1.%' identified by '123123';
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
Slave配置
設置server-id、啓用relay-log中繼日誌
vim /etc/my.cnf
[mysqld]
relay-log = relay_log #中繼日誌
server-id = 3
innodb_file_per_table = ON
skip_name_resolve = ON
重啓master、slave服務
service mysqld restart
複製操作
在Master查看bin-log日誌文件及位置
mysql> show master logs;
+-------------------+-----------+
| Log_name | File_size |
+-------------------+-----------+
| master_bin.000001 | 120 |
+-------------------+-----------+
1 row in set (0.00 sec)
mysql> show master status;
+-------------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+-------------------+----------+--------------+------------------+-------------------+
| master_bin.000001 | 525 | | | |
+-------------------+----------+--------------+------------------+-------------------+
1 row in set (0.00 sec)
在slave中向master服務器建立複製鏈接，MASTER_LOG_POS=0;表示從第一行位置開始複製。
在slave中建立授權訪問
mysql> CHANGE MASTER TO MASTER_HOST='192.168.1.202',
-> MASTER_USER='repluser',
-> MASTER_PASSWORD='123123',
-> MASTER_LOG_FILE='master_bin.000001',
-> MASTER_LOG_POS=0;
Query OK, 0 rows affected, 2 warnings (0.03 sec)
Mysql>start slave; //啓動從服務器複製
mysql> show slave status\G; //從服務器查看複製狀態

Master，slave同步測試
在master中創建sync_db庫及test1表，並添加一條記錄
mysql> create database sync_db;
Query OK, 1 row affected (0.00 sec)
mysql> use sync_db;
Database changed
mysql> create table test1( id int(10));
Query OK, 0 rows affected (0.01 sec)
mysql> insert into test1 values(10);
Query OK, 1 row affected (0.00 sec)
mysql> select * from test1;
