安裝mysql
yum -y install mysql-devel mysql-server
運行安全設置嚮導
mysql_secure_installation
主服務器
cp /usr/share/mysql/my-large.cnf /etc/my.cnf (my-large是一個註釋了很多配置的文件)
修改master端的/etc/my.cnf文件
server_id = 1 (爲1表示master,2表示slave)
binlog-do-db = test(test表示要同步的數據庫)，如果有多個數據庫，每個數據庫一行
binlog-ignore-db= mysql 設置不需要同步的數據庫，每個數據庫一行 （一般這條可以不寫）（若該2條都不寫，就代表同步全部）
log-bin = mysql-bin
進入mysql（不要忘記；）
創建一個數據庫test
create database test;
創建同步用戶
在主服務器上爲從服務器建立一個連接帳戶，該帳戶必須授予REPLICAITON SLAVE權限。
mysql> grant replication slave on *.* to 'replication'@'10.236.51.152' identified by 'password';
mysql> flush privileges;
重啓mysql
mysql> flush tables with read lock;
Query OK, 0 rows affected (0.00 sec)
mysql> show master status\G
*************************** 1. row ***************************
File: mysql-bin.000002（這個在slave的配置中要用到）
Position: 329（這個在slave的配置中要用到）
Binlog_Do_DB: test
Binlog_Ignore_DB: mysql
1 row in set (0.00 sec)
mysql> unlock tables;
注：這裏鎖表的目的是爲了生產環境中不讓進新的數據，好讓從服務器定位同步位置。初次同步完成後，記得解鎖。
從服務器
cp /usr/share/mysql/my-large.cnf /etc/my.cnf
修改master端的/etc/my.cnf文件
[mysqld]
server-id = 2
log-bin = mysql-bin
replicate-do-db = test
replicate-ignore-db = mysql,information_schema
重啓mysql
用change master語句指定同步位置
mysql> change master to master_host='10.236.51.151', master_user='replication', master_password='password', master_log_file='mysql-bin.000002', master_log_pos=0;
