redis-3主3从1专用哨兵--程序分片配置
本项目采用redis3主3从，程序端分片。
一、redis安装
1、安装
vi /etc/resolv.conf
yum -y install gcc openssl-devel pcre-devel zlib-devel openssl pcre wget ruby rubygems vim tree lsof gcc-c++ libstdc++-devel tcl
yum -y install gcc gcc-c++ libstdc++-devel tcl
mkdir /data
cd /data
wget ftp://182.168.1.249/pub/redis/redis-3.0.0.tar.gz
tar xzvf redis-3.0.0.tar.gz -C /usr/local/
mv /usr/local/redis-3.0.0 /usr/local/redis
cd /usr/local/redis/src
make && make test
2、主从配置
主
cd /usr/local/redis/
vi redis.conf
./src/redis-server redis.conf
./src/redis-cli -p 6379
主配置文件
daemonize yes
port 6379
从
cd /usr/local/redis/
vi redis.conf
./src/redis-server redis.conf
./src/redis-cli -p 16379
从配置文件
daemonize yes
port 16379
slaveof 192.168.2.81 6379
2、手动切换测试
主
./src/redis-cli -p 6379 shutdown
从
./src/redis-cli -p 6380 slaveof NO ONE
写入测试
启动主、回切
./src/redis-cli -p 6380 slaveof 192.168.2.81 6379
3、rdb文件备份
redis目录下的dump.rdb 需要备份
二、哨兵配置
1、所有主机都配置
