一. 安裝包選擇:

      mysql-5.0.19.tar.gz

二. 安裝環境:

主服務器:   192.168.0.201

從服務器:   192.168.0.00

三.主服務器配置:

Ø         建立用戶
grant replication slave on *.* to user001@192.168.0.200 identified by ‘111111′

Ø         編輯配置文件/etc/my.cnf
server-id = 1
log-bin=mysql-bin
binlog-do-db=test
binlog-ignore-db=mysql

注:

 # grant replication slave on *.* to ‘用戶名’@'主機’ identified by ‘密碼’;
# binlog-do-db=需要備份的數據庫名，可寫多行
# binlog-ignore-db=不需要備份的數據庫名，可寫多行

       # 可在B Slave上做連接測試: mysql -h 192.168.0.200 -u test -p

四.從服務器配置:

Ø        編輯/etc/my.cnf

server-id=2
server-id=2       記得是兩個???
log-bin=mysql-bin
master-host=192.168.0.201
master-user=user001
master-password=111111
master-port=3306
replicate-do-db=test
replicate-do-db=test1
# replicate-do-db=test  需要備份的數據庫名
# replicate-ignore-db=mysql 忽略的數據庫
# master-connect-retry=60 如果從服務器發現主服務器斷掉，重新連接的時間差(秒)

先手動同步一下主從服務器中要備份的數據庫，再重啟主，從服務器。

五.驗證是否配置正確:

     # mysql>  slave start;

     # mysql>  show slave status\G;

*************************** 1. row ***************************

             Slave_IO_State: Waiting for master to send event

                Master_Host: 192.168.0.201

                Master_User: repluser1

                Master_Port: 3306

              Connect_Retry: 60

            Master_Log_File: mysql-bin.000045

        Read_Master_Log_Pos: 212

            Relay_Log_Space: 235

            Until_Condition: None

             Until_Log_File:

              Until_Log_Pos: 0

         Master_SSL_Allowed: No

         Master_SSL_CA_File:

         Master_SSL_CA_Path:

            Master_SSL_Cert:

          Master_SSL_Cipher:

             Master_SSL_Key:

      Seconds_Behind_Master: 0

1 row in set (0.00 sec)

確如如下行一致:
Waiting for master to send event
Slave_IO_Running: Yes
Slave_SQL_Running: Yes

其他: ++主服務器上的相關命令
show master status
show slave hosts
show logs
show binlog events
purge logs to ‘log_name’
purge logs before ‘date’
reset master(老版本flush master)
set sql_log_bin=

++從服務器上的相關命令
slave start
slave stop
SLAVE STOP IO_THREAD //此線程把master段的日志寫到本地
SLAVE start IO_THREAD
SLAVE STOP SQL_THREAD //此線程把寫到本地的日志應用于數據庫
SLAVE start SQL_THREAD
reset slave
SET GLOBAL SQL_SLAVE_SKIP_COUNTER
load data from master
show slave status(SUPER,REPLICATION CLIENT)
CHANGE MASTER TO MASTER_HOST=, MASTER_PORT=,MASTER_USER=, MASTER_PASSWORD= //動態改變master信息
PURGE MASTER [before ‘date’] 刪除master端已同步過的日志

++產生了mysql-bin.00000x文件可以刪除

附一: mysql無法啟動:

# /usr/local/mysql//bin/mysqld_safe --user=mysql --log-error=err.txt

# more err.txt 根據里面的提示信息進行判斷分析

附二: 解決mysql“Access denied for user 'root'@'localhost'”

mysql -uroot -p
Enter password:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
修改root用戶的密碼：
# mysqladmin -uroot -p password 'newpassword' -
