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）
