mysql主从配置完整版（二进制安装）

系统基础

centos6.5

mysql5.6

防火墙关闭，目录挂载等

fdisk /dev/sdb

vgcreate datavg /dev/sdb1

lvcreate -L 99G -n datalv datavg

mkfs.ext4 /dev/datavg/datalv

mkdir /data

mount /dev/datavg/datalv /data/

echo "/dev/datavg/datalv /data/ ext4 defaults 0 0" >>/etc/fstab

mkdir /data/mysqldata

ip规划

10.249.1.99 master

10.249.1.97 slave

安装脚本脚本编辑（自己拿去测试一下）

主从配置

sed -i 's/^# log_bin/log_bin = \mysql_bin.log/' /etc/my.cnf

设置密码

/usr/local/mysql/bin/mysqladmin -u root password '123'

或

/usr/local/mysql/bin/mysqladmin -u root -h mysql1 password 'new-password'

删除空用户

登陆MySQL并且删除空用户

mysql> SELECT user,host,password FROM mysql.user;

| root | 10-4-5-9 | |

从节点

change master to master_host='10.249.1.99',master_user='wolf',master_password='wolf',master_log_file='mysql_bin.000002', master_log_pos=407;

start slave;

show slave status\G;

测试

mysqlbinlog /mysql/data/mysql-bin.000002

mysql> use mysql；

mysql> create database hehe;

mysql> show databases;

mysql> show tables;

mysql> use hehe

mysql> show tables;

mysql> create table bbb (id int ,name varchar(20) );

mysql> show tables;

mysql> insert into bbb id,name values(1,'123');

mysql> show master status;

mysql> select * from bbb;

mysql> create database lang;

从库上查看

show create table bbb;
