mysql5.6基于GTID的主从复制

mysql5.6gtid模式的主从复制:

1.配置master的my.cnf文件:
    ##################master
    [mysqld]
    basedir = /usr/local/mysql
    datadir = /home/data/mysqldb
    socket = /home/data/mysqldb/mysql.sock
    port = 3306
    server_id = 1
    user=mysql
    
    binlog-format=ROW
    log-bin=master-bin.log-bin
    log-slave-updates=true
    gtid-mode=on
    enforce-gtid-consistency=true
    master-info_repository=TABLE
    relay-log-info-repository=TABLE
    sync-master-info=1
    slave-parallel-worker=2
    slave_allow_batching = 1  
    master-verify-checksum=1  
    slave-sql-verify-checksum=1
    binlog-rows-query-log-events=1
    server-id=1
    port=3306
    report-port=3306
    report-host=192.168.100.3
    lower_case_table_names=1
    #安装完半同步插件后即可在配置文件中打开下面的选项
    #rpl_semi_sync_slave_enabled=1
    #rpl_semi_sync_master_enabled=1
    #rpl_semi_sync_master_timeout=2000

2.配置master的my.cnf文件:
    ##################slave
    [mysqld]
    basedir = /usr/local/mysql
    datadir = /home/data/mysqldb
    socket = /home/data/mysqldb/mysql.sock
    port = 3306
    server_id = 1
    user=mysql
    binlog-format=ROW
    log-bin=master-bin.log-bin
    enforce-gtid-consistency=true
    master-info_repository=TABLE
    relay-log-info-repository=TABLE
    sync-master-info=1
    slave-parallel-worker=2
    slave_allow_batching = 1  
    master-verify-checksum=1  
    slave-sql-verify-checksum=1
    binlog-rows-query-log-events=1
    server-id=2
    report-port=3306
    port=3306
    report-host=192.168.100.5
    #安装完半同步插件后即可在配置文件中打开下面的选项
    #rpl_semi_sync_slave_enabled=1
    #rpl_semi_sync_master_enabled=1
    #rpl_semi_sync_master_timeout=1000
3.备份主数据库(须安装perconna-xtrabackup软件):
    innobackupex  --user=backupuser --password=backupuser --no-timestamp /tmp/bak/fullbk
    将/tmp/bak/fullbk下的备份文件传至从库的/tmp/bak/fullbk目录下,并执行如下语句:
    innobackupex --apply-log /tmp/bak/fullbk
    将/tmp/bak/fullbk目录下的文件拷贝至datadir的目录中即可;

4.安装同步插件并授权:
    在mysql主从数据库中安装半同步插件:
    install plugin rpl_semi_sync_master soname ‘semisync_master.so‘;
    install plugin rpl_semi_sync_slave soname ‘semisync_slave.so‘;

在mysql的主从数据库中授权,并开启半同步:
    GRANT REPLICATION SLAVE ON *.* TO ‘repl‘@‘192.168.100.3‘ IDENTIFIED BY ‘repl‘;
    GRANT REPLICATION SLAVE ON *.* TO ‘repl‘@‘192.168.100.5‘ IDENTIFIED BY ‘repl‘;
    set global rpl_semi_sync_slave_enabled=1;
    set global rpl_semi_sync_master_enabled=1;
    set global rpl_semi_sync_master_timeout=1000;

5.启动同步:
    change master to master host=‘‘,master_user=‘‘,master_password=‘‘,master_auto_position=1;
    start slave;
6.检查:
    在mysql的主数据库中查看从客户端:
    show slave hosts;

在mysql从服务器中检查同步状态:
    mysql>show slave status\G
             Slave_IO_Running: Yes
            Slave_SQL_Running: Yes
          Exec_Master_Log_Pos: 34810
        Seconds_Behind_Master: 4
             Master_Server_Id: 1
                Auto_Position: 1
7.至此,完成基于GTID的主从配置
