1.數(shù)據(jù)庫安裝
安裝MySQL5.7奸远，主數(shù)據(jù)庫為192.168.2.221墨礁，從數(shù)據(jù)庫為192.168.2.222，服務器內(nèi)存8G
sudo apt-get install mysql-server
2.主數(shù)據(jù)庫配置
修改/etc/mysql/my.cnf
#master
[mysqld]
#replicate
server_id = 1
#replicate database
binlog-do-db = test
log_bin = mysql-bin
進入數(shù)據(jù)庫俯在，添加同步用戶
shell>mysql -uroot -p
mysql>create user ‘repl’@’%’ identified by ‘password’;
mysql>grant replication slave on * . * to ‘repl’@’%’;
記錄master信息粒督，F(xiàn)ile和Position
mysql>show master status\G
***************** 1. row *****************

重啟數(shù)據(jù)庫
sudo /etc/init.d/mysql restart
3.從數(shù)據(jù)庫配置
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;
重啟數(shù)據(jù)庫
shell>sudo /etc/init.d/mysql restart
shell>mysql -uroot -p
mysql>show slave status\G;

4.批量插入性能
批量插入語句
insert into mt_data(mac,time,device_id,intensity,ap_mac,channel,virtual_type)values(……)*n
n為300時，每秒插入達到35000條數(shù)據(jù)
