记录

环境：ubuntu16.04，mysql5.7

主机：192.168.1.240,192.168.1.241；241为Salve

1.安装mysql

sudo apt-get install mysql-server

2.为master增加slave用户

进入mysql

grant replication slave on *.* to ‘slave‘@‘192.168.1.241‘ identified by ‘password‘;

3.编辑配置文件

master：

vim /etc/mysql/mysql.conf.d/mysqld.cnf

bind-address = 192.168.1.240 #这个一定要配，否则Slave连不上
server-id = 1
log_bin = /var/log/mysql/mysql-bin.log
expire_logs_days = 10
max_binlog_size = 100M
relay-log=mysql-relay-bin
log_slave_updates=on
auto_increment_increment=2
auto_increment_offset=1

slave：

server-id = 2
auto_increment_increment=2
auto_increment_offset=2

4.在Master和Slave上创建相同的库与表

5.开启Slave

（1）240查询Master日志Position

show master status;

（2）在241设置Slave并启动

change master to master_host=‘192.168.1.240‘,master_user=‘slave‘,master_password=‘password‘,master_port=3306,MASTER_LOG_FILE=‘mysql-bin.000007‘, MASTER_LOG_POS=1068;

start slave;

查询slave状态

show slave status\G;

进行数据验证
