redis-3主3從1專用哨兵--程式分片配置
阿新 • • 發佈：2018-12-24
本專案採用redis3主3從，程式端分片。
一、redis安裝
1、安裝
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、主從配置
主
cd /usr/local/redis/
vi redis.conf
./src/redis-server redis.conf
./src/redis-cli -p 6379
主配置檔案
daemonize yes
port 6379
從
cd /usr/local/redis/
vi redis.conf
./src/redis-server redis.conf
./src/redis-cli -p 16379
從配置檔案
daemonize yes
port 16379
slaveof 192.168.2.81 6379
2、手動切換測試
主
./src/redis-cli -p 6379 shutdown
從
./src/redis-cli -p 6380 slaveof NO ONE
寫入測試
啟動主、回切
./src/redis-cli -p 6380 slaveof 192.168.2.81 6379
3、rdb檔案備份
redis目錄下的dump.rdb 需要備份
二、哨兵配置
