MySQL 5.7 主从数据库搭建

[日期:2018-08-31] 来源:Linux社区  作者:Linux [字体: ]

1.数据库安装

安装MySQL5.7,主数据库为192.168.2.221,从数据库为192.168.2.222,服务器内存8G

sudo apt-get install mysql-server

2.主数据库配置

  • 修改/etc/mysql/my.cnf

    #master

    [mysqld]

    #common
    port = 3306
    bind-address = 0.0.0.0
    skip-name-resolve
    max_connections = 512

    #replicate
    server_id = 1
    #replicate database
    binlog-do-db = test
    log_bin = mysql-bin

    #innodb
    innodb_buffer_pool_size = 6G
    innodb_flush_method = O_DIRECT
    innodb_log_buffer_size = 16M
    innodb_log_file_size = 2G
    innodb_log_files_in_group = 2

    sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

  • 进入数据库,添加同步用户

    shell>mysql -uroot -p

    mysql>create user ‘repl’@’%’ identified by ‘password’;
    mysql>grant replication slave on * . * to ‘repl’@’%’;

  • 记录master信息,File和Position

    mysql>show master status\G
    ***************** 1. row *****************
    File: mysql-bin.000001
    Position: 154
    Binlog_Do_DB: test
    Binlog_Ignore_DB:
    Executed_Gtid_Set:

  • 重启数据库

    sudo /etc/init.d/mysql restart

3.从数据库配置

  • 修改/etc/mysql/my.cnf

    #slave

    [mysqld]

    #common
    port = 3306
    bind-address = 0.0.0.0
    skip-name-resolve
    max_connections = 512

    #replicate
    server_id = 2
    #replicate database
    replicate-do-db = test

    #innodb
    innodb_buffer_pool_size = 6G
    innodb_flush_method = O_DIRECT
    innodb_log_buffer_size = 16M
    innodb_log_file_size = 2G
    innodb_log_files_in_group = 2
    sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

  • 配置slave

    shell>mysql -uroot -p
    mysql>change master to master_host =’192.168.2.221’,master_port=3306,master_user=’repl’,master_password=’password’,master_log_file=’mysql-bin.000001’,master_log_pos=154;
    mysql>start slave;

  • 重启数据库

    shell>sudo /etc/init.d/mysql restart
    shell>mysql -uroot -p
    mysql>show slave status\G;
    ***************** 1. row *****************

  • 连接成功

4.批量插入性能

批量插入语句

insert into mt_data(mac,time,device_id,intensity,ap_mac,channel,virtual_type)values(……)*n

n为300时,每秒插入达到35000条数据
