環(huán)境：master:?192.168.240.131

Slave:?192.168.240.130

需要復制的數(shù)據(jù)庫：test

1.???????Master服務器啟動mysql，

a)?????????#mysql?–uroot?–proot

b)????????創(chuàng)建一個有復制權限的用戶，只限slave遠程連接訪問.

i.??????????????mysql>grant?replication?slave?on?*.*?to?navy@192.168.240.130 identified?by?‘password’;

ii.??????????????mysql>flush?privileges;

c)?????????mysql>flush?tables?with?read?lock;?#鎖定master服務器所有表的寫入。

d)????????重新打開一終端，備份要復制的數(shù)據(jù)庫。

i.??????????????#tar?-zcvf?test.tar.gz?/data/mysql_db/test/????//test所在路徑/data/mysql_db/test/即一個庫。

ii.???????將test.tar.gz復制到從服務器上并減壓到相應的目錄下

e)?????????返回上一終端。

i.??????????????Mysql>show?master?status;

+------------------+----------+--------------+------------------+

|?File?????????????|?Position?|?Binlog_Do_DB?|?Binlog_Ignore_DB?|

+------------------+----------+--------------+------------------+

|mysql-bin.000013|???????106?|?test?????????|??????????????????|

+------------------+----------+--------------+------------------+

1?row?in?set?(0.01?sec)

其中mysql-bin.000013和106二個值將是slave與master的同步點。

f)??????????給數(shù)據(jù)庫解鎖(當備份完成后)　mysql>unlock?tables;

g)?????????編輯mysql的配置文件。Vim?/etc/my.cnf設置這三個參數(shù)，沒有的添加，有的直接更改即可。

log-bin=mysql-bin

server-id??=?1

binlog-do-db=test

保存退出。

2.???????Slave服務器配置

a)?????????將從master中備份的庫解壓到相應路徑下(退庫的導入)

i.??????????????#tar?zxvf?test.tar.gz

b)????????修改my.cnf

server-id=2

master-host=192.168.240.131

master-user=?navy

master-password=?password

log-bin=

3.???????重啟master,?slave的mysql服務

a)?????????注意順序，先重啟master-à然后是slave.

b)????????Slave服務器重啟后，登錄mysql

mysql>?stop?slave;

Query?OK,?0?rows?affected?(0.00?sec)

mysql>?change?master?to

->?master_host='192.168.0.3',

->?master_user='navy',

->?master_password='password',

->?master_log_file='mysql-bin.000013',

->?master_log_pos=106;

Query?OK,?0?rows?affected?(0.02?sec)

mysql>?start?slave;

Query?OK,?0?rows?affected?(0.00?sec)

mysql>?show?slave?status\G;
