MySQL 5.7 主从数据库搭建

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]

#replicate

server_id = 1

#replicate database

binlog-do-db = test

log_bin = mysql-bin

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:

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]

#replicate

server_id = 2

#replicate database

replicate-do-db = test

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;

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
