手动部署Redis群集
PS：一台物理机上部署redis集群
1.redis安装
cd /home
wget http://download.redis.io/releases/redis-4.0.9.tar.gz
tar xzf redis-4.0.9.tar.gz
cd redis-4.0.9/
make
--PS:如果没有安装gcc先安装 gcc-v 查看有无安装
--yum install gcc-c++
make PREFIX=/usr/local/redis install
修改/ect/profile
export REDIS_HOME=/usr/local/redis
export PATH=$PATH:$REDIS_HOME/bin
source /ect/profile
然后可在任何地方启动redis
2.Redis群集
创建相关目录，主文件夹是redis-cluster，在此文件夹下建立6个子文件夹，名称分别是：7000,7001,7002,7003,7004,7005，
该目录以我们将在任何给定目录内运行的实例的端口号命名。
cd /etc/redis/
mkdir redis-cluster
cd redis-cluster/
mkdir 7000 7001 7002 7003 7004 7005
cp /home/redis-4.0.9/redis.conf /etc/redis/redis-cluster/7000
cd 7000
修改配置文件：
vi redis.conf
bind 127.0.0.1 //绑定服务器IP地址-0本地
port 7000 //绑定端口号，必须修改，以此来区分Redis实例
daemonize yes //后台运行
pidfile /var/run/redis-7000.pid //修改pid进程文件名，以端口号命名
logfile "7000.log" //修改日志文件名称，以端口号为目录来区分
cluster-enabled yes //启用集群
cluster-config-file nodes-7000.conf //配置每个节点的配置文件，同样以端口号为名称
cluster-node-timeout 15000 //配置集群节点的超时时间，可改可不改
appendonly yes //启动AOF增量持久化策略
appendfsync always //发生改变就记录日志
529 root /etc/redis/redis-cluster/7000# cp redis.conf ../7001
530 root /etc/redis/redis-cluster/7000# cp redis.conf ../7002
531 root /etc/redis/redis-cluster/7000# cp redis.conf ../7003
532 root /etc/redis/redis-cluster/7000# cp redis.conf ../7004
533 root /etc/redis/redis-cluster/7000# cp redis.conf ../7005
切换到各个目录下
vi redis.conf
:%s/7000/700X/g 修改各个配置文件
apt-get install ruby //安装ruby
apt-get install rubygems //安装rubygems，最新版本会自动安装
gem install redis // 安装Redis的Ruby接口程序
指定配置文件 启动6个Redis实例
556 root /etc/redis/redis-cluster# redis-server 7000/redis.conf
557 root /etc/redis/redis-cluster# redis-server 7001/redis.conf
558 root /etc/redis/redis-cluster# redis-server 7002/redis.conf
559 root /etc/redis/redis-cluster# redis-server 7003/redis.conf
560 root /etc/redis/redis-cluster# redis-server 7004/redis.conf
561 root /etc/redis/redis-cluster# redis-server 7005/redis.conf
查看redis实例
ps -ef | grep redis
