windows8.1系统下配置mysql主从复制 1.测试环境概述 本地win8操作系统,64位操作系统,3G内存,的是mysql5.6.16-winx64.zip包 在本地磁盘上解压两个mysql,端口分别是3310和3311,即: localhost:3310 --master服务器 localhost:3311 --slave服务器 \
\ 2.配置master 将压缩包解压: C:/software/mysql-5.6.16-winx64-3310 在这个目录下建立tmp文件夹 在该目录下新增my.ini文件,其内容如下:
# For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html # *** DO NOT EDIT THIS FILE. It"s a template which will be copied to the # *** default location during install, and will be replaced if you # *** upgrade to a newer version of MySQL. [mysqld] server-id=1 #replicate-same-server-id=0 # Remove leading # and set to the amount of RAM for the most important data # cache in MySQL.

其中,server-id变量表示该节点在集群内的唯一表示,每个节点必须使用不同的server-id来区分 basedir,datadir,tmpdir这些表示的是数据文件或临时文件的存放路径,因为我们在一台机器上创建2个mysql服务,为了两个实例之间的数据不发生干扰,我们在配置文件中明确指定其位置 port:这个参数就是mysql服务的监听端口,这里我们设置的是3310 log-bin:要将服务器设置为master,需要确保该服务器有一个活动的二进制日志(binary log),该日志上保留了服务器上的所有改变,并且这些改变可以在slave上被重新执行 3.启动master 命令行切换到 C:\software\mysql-5.6.16-winx64-3310\bin(master解压目录),执行mysqld --console命令,得如下信息,则master启动完毕:
C:\software\mysql-5.6.16-winx64-3310\bin>mysqld --console 2014-03-26 22:20:48 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated.

4.在master上创建一个复制用户 4.1修改默认的root密码 如果是已有的数据库则该步骤,则修改密码部分省略 C:/software/mysql-5.6.16-winx64-3310\mysqladmin -uroot password 111111 通过如上命令,我们给默认的root帐号一个密码111111 4.2添加复制用户并给予权限: C:/software/mysql-5.6.16-winx64-3310 \mysql -uroot -p111111 进入到my中
mysql> create user repl_user; Query OK, 0 rows affected (0.00 sec) mysql> mysql> grant replication slave on *.* to repl_user identified by '111111'; Query OK, 0 rows affected (0.00 sec) mysql>
replication slave这个权限没有什么特别之处,只是这个用户可以从master上取得二进制的日志转储数据,完全可以给一个常规帐号赋予replication slave权限,但是最好还是将replication slave权限和其他用户权限分开,这样的话,如果后期想禁止某些slave的链接,只要删除该用户就可以了 5.配置slave 将压缩包解压: C:/software/mysql-5.6.16-winx64-3311 在这个目录下建立tmp文件夹 在该目录下新增my.ini文件,其内容如下:
# For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults. # *** DO NOT EDIT THIS FILE.

[d] server-id=2 #replicate-same-server-id=0 # Remove leading # and set to the amount of RAM for the most important data # cache in MySQL.

与master一样,slave也要配置一个唯一的服务器id,relay-log和relay-log-index表示中继日志文件和中继日志索引文件 6.启动slave 命令行切换到 C:\software\mysql-5.6.16-winx64-3311\bin(slave解压目录),执行mysqld --console命令,得如下信息,则slave启动完毕:
C:\software\mysql-5.6.16-winx64-3311\bin>mysqld --console 2014-03-26 22:21:19 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details). 2014-03-26 22:21:19 6916 [Note] Plugin 'FEDERATED' is disabled. 2014-03-26 22:21:19 6916 [Note] InnoDB: Using atomics to ref count buffer pool pages 2014-03-26 22:21:19 6916 [Note] InnoDB: The InnoDB memory heap is disabled 2014-03-26 22:21:19 6916 [Note] InnoDB: Mutexes and rw_locks use Windows interlocked functions 2014-03-26 22:21:19 6916 [Note] InnoDB: Compressed tables use zlib 1.2.3 2014-03-26 22:21:19 6916 [Note] InnoDB: Not using CPU crc32 instructions 2014-03-26 22:21:19 6916 [Note] InnoDB: Initializing buffer pool, size = 128.0M 2014-03-26 22:21:19 6916 [Note] InnoDB: Completed initialization of buffer pool 2014-03-26 22:21:19 6916 [Note] InnoDB: Highest supported file format is Barracuda. 2014-03-26 22:21:20 6916 [Note] InnoDB: 128 rollback segment(s) are active. 2014-03-26 22:21:20 6916 [Note] InnoDB: Waiting for purge to start 2014-03-26 22:21:20 6916 [Note] InnoDB: 5.6.16 started; log sequence number 1625977 2014-03-26 22:21:20 6916 [Warning] No existing UUID has been found, so we assume that this is the first time that this server has been started. Generating a new UUID: e6f98904-b4f1-11e3-9ec5-904ce5e379cc. 2014-03-26 22:21:20 6916 [Note] Server hostname (bind-address): '*'; port: 3311 2014-03-26 22:21:20 6916 [Note] IPv6 is available. 2014-03-26 22:21:20 6916 [Note] - '::' resolves to '::'; 2014-03-26 22:21:20 6916 [Note] Server socket created on IP: '::'. 2014-03-26 22:21:21 6916 [Note] Event Scheduler: Loaded 0 events 2014-03-26 22:21:21 6916 [Note] mysqld: ready for connections. Version: '5.6.16' socket: '' port: 3311 MySQL Community Server (GPL)
7.将slave连接到master上 现在创建基本的复制只剩最后一步了:将slave指向master,让它知道从哪里进行复制,为此你需要知道master的4个信息:主机名,主机端口号,主机数据库用户,主机数据库帐号密码,因为创建master的时候已经创建了一个复制用户,因此在slave节点上执行如下指令:
mysql> change master to master_host='localhost',master_port=3310,master_user='repl_user',master_password='111111'; Query OK, 0 rows affected, 2 warnings (0.45 sec) mysql>
mysql> start slave; Query OK, 0 rows affected (0.05 sec) mysql>
8.常见问题排查 执行如上命令后,输出如下信息: 2014-03-26 23:11:23 6916 [ERROR] Slave I/O: error connecting to master [email protected]:3310' - retry-time: 60 retries: 1, Error_code: 1045 这个说明slave和master之间的链接没有建立成功,这个时候多半是添加了新用户repl_user后,没有生效导致 在master上执行flush privileges;来将新建的用户及权限生效
