#啓動服務

################################# mysql 完整安裝完成 ###########################
按照上面的步驟兩臺服務器同時安裝,並保證可以啓動mysql
1. 理想情況，應在主服務器和從服務器上使用最近版本的MySQL。
2. 在主服務器上爲服務器設置一個連接賬戶。
mysql> GRANT REPLICATION SLAVE ON *.* TO 'test'@'192.168.0.2' IDENTIFIED BY 'db@test';
3. 關閉主從數據庫
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 #設置主機id標識
binlog-do-db = test #設置需要同步的數據庫，如果有多個數據庫，每個數據庫一行
log-bin = /data/mysql5051_db/binlog/master.log #mysql日誌
7. 修改從數據庫的配置文件 my.cnf
linux-B:/etc # vi my.cnf
在[mysqld] 段內加入
server-id = 2 #設置從機id標識,如果有多個從機，可以順序增加ID爲3,4...
master-host = 192.168.0.1 #主機地址
master-user = test #主機mysql數據庫用戶
master-password = db@test #主機mysql數據庫密碼
replicate-do-db = test #同步的數據庫，如果有多個數據庫，每個數據庫一行
log-bin = /data/mysql5051_db/binlog/slave.log #本機mysql日誌
relay-log = /data/mysql5051_db/binlog/relay.log #同步日誌
log-slave-updates #同步方式
read-only
master-connect-retry=60
8. 開啓主從數據庫
/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.導入數據
主:
create database test
這裏備機也會有這個庫了，也就是說MYSQL將創建數據庫的操作也同步了，夠強吧。
然後，再把數據導入即可：
root@test:/data# /usr/local/mysql/bin/mysql test <./db.dump
上備機，查看數據,也已經OK。
mysql啓動時,如果./configure時不指定--defaults-extra-file=/usr/local/mysql/data/my-small.cnf
默認就是--defaults-extra-file=/etc/my.cnf
