服務器節點兩臺: 192.168.1.129（主），192.168.1.131（從）
一，192.168.1.129（主）/etc/my.cnf配置文件加入
# # server-id 唯一的服務辨識號,數值位於 1 到 2^32-1之間.
# # 此值在master和slave上都需要設置.
# # 如果 “master-host” 沒有被設置,則默認爲1, 但是如果忽略此選項,MySQL不會作爲master生效.
server-id = 1
#[必須]啓用二進制日誌
log-bin = mysql-bin
# # 需要開啓生成二進制日誌記錄相關配置，配置在需要被複制的服務器上，即：master
#指定對名稱爲test_db的數據庫記錄二進制日誌
binlog-do-db = test
#指定不對名稱爲mysql的數據庫記錄二進制日誌
binlog-ignore-db = mysql
#指定不對名稱爲information_schema的數據庫記錄二進制日誌 #
binlog-ignore-db = information_schema
#binlog日誌格式，mysql默認採用，如果從服務器slave有別的slave要複製那麼該slave也需要這一項#
binlog_format = mixed
#超過7天的binlog刪除###
expire_logs_days = 7
重啓mysql後，連接進mysql 查看狀態
[root@localhost ~]# mysql -u root -p

主數據庫配置完成
二， 192.168.1.131（從）/etc/my.cnf配置文件加入
server-id = 2
#需要做複製的數據庫,如果複製多個數據庫，重複設置這選項即可master上不需要此項，slave上需要
replicate-do-db = test
#不需要複製的數據庫，如果要忽略複製多個數據庫，重複設置這個選項即可
replicate-ignore-db = mysql
replicate-ignore-db = information_schema
#MySQL選項以避免外部鎖定。該選項默認開啓
skip-external-locking
#默認存儲引擎
default-storage-engine = InnoDB
#停止從服務器
mysql> stop slave;
#重置從服務器
mysql> reset slave;
#從服務器關聯到主服務器
mysql> change master to master_user='hxs',
master_password='123456',
master_host='192.168.1.129',
master_port=3306,
#可以在主數據庫129上通過 show master status 查看
master_log_file='mysql-bin.000002',
master_log_pos=1388;
#開啓從服務器
mysql> start slave
#查看從服務器連接狀態
mysql> show slave status\G ;

是否成功就看
Slave_IO_Running: Yes
Slave_SQL_Running: Yes
是否都爲Yes
如果有出現以上結果，則配置成功！
三，驗證主從是否可以成功同步，在主庫中進行增刪改查，看從表能否正確同步
