################################# mysql 完整安裝完成 ###########################按照上面的步驟兩台伺服器同時安裝,並保證可以啟動mysql1. 理想情況，應在主伺服器和從伺服器上使用最近版本的MySQL。
2. 在主伺服器上為伺服器設定一個串連賬戶。
mysql> GRANT REPLICATION SLAVE ON *.* TO 'test'@'192.168.0.2' IDENTIFIED BY 'db@test';
3. 關閉主從資料庫
linux-A:/data # /usr/local/mysql/bin/mysqladmin shutdown
linux-B:/data # /usr/local/mysql/bin/mysqladmin shutdown
linux-A:/etc # vi my.cnf
在[mysqld] 段內加入
server-id = 1 #設定主機id標識
binlog-do-db = test #設定需要同步的資料庫，如果有多個資料庫，每個資料庫一行
log-bin = /data/mysql5051_db/binlog/master.log #mysql日誌
7. 修改從資料庫的設定檔 my.cnf
linux-B:/etc # vi my.cnf
在[mysqld] 段內加入
server-id = 2 #設定從機id標識,如果有多個從機，可以順序增加ID為3,4...
master-host = 192.168.0.1 #主機地址
master-user = test #主機mysql資料庫使用者
master-password = db@test #主機mysql資料庫密碼
replicate-do-db = test #同步的資料庫，如果有多個資料庫，每個資料庫一行
log-bin = /data/mysql5051_db/binlog/slave.log #本機mysql日誌
relay-log = /data/mysql5051_db/binlog/relay.log #同步處理記錄
log-slave-updates #同步方式
read-only
master-connect-retry=60
8. 開啟主從資料庫
/usr/local/mysql/bin/mysqld_safe -umysql &9. 看同步情況
mysql> show slave status\G
Slave_IO_Running: Yes
Slave_SQL_Running: Yes
證明同步已經成功!
10.匯入資料
主:
create database test
這裡備機也會有這個庫了，也就是說MYSQL將建立資料庫的操作也同步了，夠強吧。
然後，再把資料匯入即可：
root@test:/data# /usr/local/mysql/bin/mysql test <./db.dump
上備機，查看資料,也已經OK。 mysql啟動時,如果./configure時不指定--defaults-extra-file=/usr/local/mysql/data/my-small.cnf
預設就是--defaults-extra-file=/etc/my.cnf
