这么一个简单问题,在ubuntu居然搞了两天,终于搞定了。 中途出了点问题,搞的郁闷一天的问题就是 change master 语句,好了下面就开始讲正题吧。 linux OS: ubuntu server 8.04.1 software: mysql5.0.51 mysql1 : 192.168.6.4 //master mysql2 : 192.168.6.5 //slave 安装步骤 1. 分别在两台机器上安装mysql-server shell > apt-get install mysql-server 2.修改 mysql1 master 的配置文件 vim /etc/mysql/my.cnf 找到 bind-address = 127.0.0.1 改为 bind-address = 0.0.0.0 找到 #server-id = 1 #log_bin = /var/log/mysql/mysql-bin.log 去掉 注释符号 server-id = 1 log_bin = /var/log/mysql/mysql-bin.log default-character-set = utf8 #新加上的为了保持编码一至防止出错 3.改好后保存退出,然后建立一个slave服务器的用户账号 root@msyql1:/# mysql -uroot -p mysql> grant replication slave,replication client on *.* to ludy@'192.168.6.5' identified by 'ypmwbg'; mysql > grant replication slave on *.* to ludy@192.168.6.5 identified by 'ypmwbg'; //给予权限 到这里要注意了,我的两台数据库都是空的. 重启mysql服务 4.修改 mysql2 服务器slave的 my.cnf配置文件 找到 bind-address = 127.0.0.1 替换 bind-address = 0.0.0.0 找到 #server-id = 1 #log_bin = /var/log/mysql/mysql-bin.log 把 注释符号去掉 改为如下 server-id = 2 master-host = 192.168.6.4 master-user = ludy master-password = ypmwbg master-port = 3306 log_bin = /var/log/mysql/mysql-bin.log log-slave-updates skip-slave-start 配置完后 重新启动mysql 然后进入 mysql1 master 服务器 root@msyql:~# mysql -uroot -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 9 Server version: 5.0.51a-3ubuntu5.4-log (Ubuntu) Type 'help;' or '\h' for help. Type '\c' to clear the buffer. mysql> show master status; +------------------+----------+--------------+------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | +------------------+----------+--------------+------------------+ | mysql-bin.000001 | 98 | | | +------------------+----------+--------------+------------------+ 1 row in set (0.00 sec) 记录下来以后 进入 mysql2 slave mysql root@msyql2:~# mysql -uroot -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 9 Server version: 5.0.51a-3ubuntu5.4-log (Ubuntu) Type 'help;' or '\h' for help. Type '\c' to clear the buffer. mysql> change master to master_log_file='mysql-bin.000001', master_log_pos=98; //这个地方就是记录下来的 mysql1 master 的数据 mysql > start slave; //启动slave 服务 mysql > show slave status\G *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: 192.168.6.4 Master_User: ludy Master_Port: 3306 Connect_Retry: 60 Master_Log_File: mysql-bin.000001 Read_Master_Log_Pos: 181 Relay_Log_File: mysqld-relay-bin.000003 Relay_Log_Pos: 235 Relay_Master_Log_File: mysql-bin.000001 Slave_IO_Running: Yes Slave_SQL_Running: Yes Replicate_Do_DB: Replicate_Ignore_DB: Replicate_Do_Table: Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 0 Last_Error: Skip_Counter: 0 Exec_Master_Log_Pos: 181 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 (0.01 sec) 哈哈 Slave_IO_Running: Yes Slave_SQL_Running: Yes 说明启动成功 然后在 master 新建 一个数据库看看 root@msyq1l:/# mysql -uroot -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 8 Server version: 5.0.51a-3ubuntu5.4-log (Ubuntu) Type 'help;' or '\h' for help. Type '\c' to clear the buffer. mysql> create database chenggong; Query OK, 1 row affected (0.00 sec) 在 salve 查看看是否同步 mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | chenggong | //同步了哈哈 ~ | mysql | | test | +--------------------+ 4 rows in set (0.01 sec) 好了就写这么多,如果你作 master-slave 的时候 你的master 数据里有数据那么 你必须 在 我写的 第三步与第四步中加入一下步骤: 接 上文 第三步
进入master数据库的Mysql控制台执行 mysql >FLUSH TABLES WITH READ LOCK; //锁表 然后从新打开一个 终端 拷贝 master 的所有的数据到 slave 服务器覆盖 读取 master 二进制文件与偏移量 mysql > show master status; 同样 要记录下 file 与 position 的值 然后解锁 mysql > unlock tables;
