Redis Sentinel集群部署

单机 Redis Sentinel 架构

部署规划

主机地址	作用
127.0.0.:7000	主节点
127.0.0.:7001	从节点
127.0.0.:7002	从节点

安装redis

wget http://download.redis.io/releases/redis-5.0.7.tar.gz
tar xzf redis-5.0.7.tar.gz
cd redis-5.0.7
make

主节点配置

port 7000
daemonize yes
pidfile /var/run/redis-7000.pid
logfile "7000.log"
dir "/opt/soft/redis/redis/data/"

从节点配置

port 7001
daemonize yes
pidfile /var/run/redis-7001.pid
logfile "7001.log"
dir "/opt/soft/redis/redis/data/"
replicaof 127.0.0.1 7000

测试主从是否正常

#没有sudo的话权限不足无法连接成功
sudo src/redis-server redis-7000.conf
sudo src/redis-server redis-7001.conf
sudo src/redis-server redis-7002.conf
src/redis-cli -p 7000 info replication

Sentinel 配置

#去除注释
cat sentinel.conf  | grep -v "#" | grep -v "^$" > redis-sentinel-26379.conf
vim redis-sentinel-26379.conf
#-------------文件内容---------------------
port 26379
daemonize yes
pidfile "/var/run/redis-sentinel.pid"
logfile "26379.log"
dir "/tmp"
#------------------------------------------
#快速配置
sed "s/26379/26380/g" redis-sentinel-26379.conf > redis-sentinel-26380.conf
sed "s/26379/26381/g" redis-sentinel-26379.conf > redis-sentinel-26381.conf
#启动Sentinel
src/redis-sentinel  redis-sentinel-26379.conf
src/redis-sentinel  redis-sentinel-26380.conf
src/redis-sentinel  redis-sentinel-26381.conf
