安裝redis集群

安裝zlib

yum install -y zlib

安裝ruby

yum install -y ruby

gem install redis-3.3.5.gem

> tar xvf redis-4.0.6.tar.gz

> cd redis-4.0.6
> make
> make test
> mkdir -p /redis/redis-4.0.6/cluster/8001
> cp /redis/redis-4.0.6/redis.conf /redis/redis-4.0.6/cluster/8001
> vi redis.conf

bind 192.168.0.47

port 8001

daemonize yes #以守護程序執行

pidfile /redis/redis-4.0.6/cluster/8001/redis_8001.pid

logfile /redis/redis-4.0.6/cluster/8001/redis_8001.log

dir /redis/redis-4.0.6/cluster/8001/

masterauth redis_ #集群密碼

requirepass redis_ #登陸密碼

maxclients 2048

export path=./:/redis/redis-4.0.6/src/:$

所有節點啟動redis

redis-server ./redis.conf
