redis主从复制配置

1、环境
系统发行版centos6.9
master 192.168.50.53:6401
slave1 192.168.50.53:6400
slave2 192.168.50.53:6379
这里仅作测试，所有的master和slave都在一台机器上面。

2、安装redis

# cd /usr/local #安装目录
# wget http://download.redis.io/releases/redis-3.2.8.tar.gz
# tar xzf redis-3.2.8.tar.gz
# mv redis-3.2.8/ redis
# cd redis
# make
# make install

安装过程可能会因为缺少包导致报错，安装提示操作安装一下
参考这里，或者谷歌一下

3、准备配置文件

mkdir /etc/redis
touch /etc/redis/redis-6379.conf
touch /etc/redis/redis-6400.conf
touch /etc/redis/redis-6401.conf

配置文件主要配置以下部分

bind 0.0.0.0
port 6400
daemonize yes
pidfile /var/run/redis_6400.pid
logfile /var/log/redis/redis-6400.log
dir /var/lib/redis-6400
masterauth 123456
requirepass 123456
