安装之前，最好把防火墙关闭，防止因为防火墙导致各个ip之间通讯受阻；
本次实验是采用脚本源码包安装redis；

1，新建redis集群

ps -ef|grep redis
pkill redis
cd /usr/local/
rm -rf redis
cd src/
rm -rf redis-4.0.9
tar -zxvf redis-4.0.9-v1.tar.gz
cd redis-4.0.9/
sh install.sh （需要root用户执行）

1.1，install.sh内容

[weblogic@its-redis01 redis-4.0.9]$ cat install.sh 
#!/bin/bash

read -p "1.alone
2.cluster
choice cluster or alone:" num

#create user weblogic
user_flag=`cat /etc/passwd |grep '^weblogic:' -c`
user_name='weblogic'
if [ $user_flag -eq 0 ];then
	useradd -d /home/weblogic $user_name
	echo "weblogic" | passwd $user_name --stdin
fi

vm_flag=`cat /etc/sysctl.conf |grep 'vm.overcommit_memory=1' -c`
if [ $vm_flag -eq 0 ];then
	echo "vm.overcommit_memory=1" >>/etc/sysctl.conf
	sysctl -p >/dev/null
fi

cp -r /usr/local/src/redis-4.0.9 /usr/local/redis

#input ip port
read -p "input localhost IP:" ip
read -p "input redis port:" port

if [ $num -eq 1 ];then
	sed -i "s/bind 127.0.0.1/bind $ip/" /usr/local/redis/redis-alone.conf
	sed -i "s/port 6379/port $port/" /usr/local/redis/redis-alone.conf
	chown -R weblogic:weblogic /usr/local/redis
	su - weblogic -c "cd /usr/local/redis && sh start.sh"
	if [ $? -eq 0 ];then
		echo "start redis alone done!"
	else
		echo "start redis alone fail!"
	fi

elif [ $num -eq 2 ];then
	mkdir -p /usr/local/redis/cluster/$port
	file=/usr/local/redis/cluster/$port/redis-cluster.conf
	cp /usr/local/redis/cluster/redis-cluster.conf $file
	cp /usr/local/redis/cluster/start.sh /usr/local/redis/cluster/$port
	sed -i "s/bind 127.0.0.1/bind $ip/" $file
	sed -i "s/port 6379/port $port/" $file
	cd /usr/local/redis/cluster/$port
	chown -R weblogic:weblogic /usr/local/redis
	su - weblogic -c "cd /usr/local/redis/cluster/$port && sh start.sh"
	if [ $? -eq 0 ];then
                echo "start redis cluster done!"
        else
                echo "start redis cluster fail!"
        fi
fi

1.2，start.sh内容

[weblogic@its-redis01 redis-4.0.9]$ cd /usr/local/redis/cluster/16001
[weblogic@its-redis01 16001]$ cat start.sh 
#!/bin/bash

../../src/redis-server redis-cluster.conf

1.3，redis-cluster.conf内容

2，添加集群节点(在1192.168.0.2执行即可)

cd /usr/local/redis/src/
./redis-cli -c -h 192.168.0.2 -p 16010 -a test123 进入集群命令行（IP端口对应创建的）
CLUSTER MEET 192.168.0.3 16010
CLUSTER MEET 192.168.0.4 16010

补充：若需要添加从节点，得先添加集群节点，然后登录从节点，执行CLUSTER REPLICATE 主节点node_id

3，分配slot（在192.168.0.2执行即可）

cd /usr/local/redis/src/
for i in {0…5460}; do ./redis-cli -c -h 192.168.0.2 -p 16010 -a test123 CLUSTER ADDSLOTS $i > /dev/null;done
for i in {5461…10922}; do ./redis-cli -c -h 192.168.0.3 -p 16010 -a test123 CLUSTER ADDSLOTS $i > /dev/null;done
for i in {10923…16383}; do ./redis-cli -c -h 192.168.0.4 -p 16010 -a test123 CLUSTER ADDSLOTS $i > /dev/null;done

4，redis常用集群命令

4.1 redis常用命令1

登录redis:
cd /usr/local/redis/src && ./redis-cli -c -h 10.104.120.56 -p 16001 -a 666666

授权：
auth 666666

查看它的主从节点：
cluster nodes 

查看状态：
cluster info

日志查看：/usr/local/redis/cluster/16001下的   redis.log

关闭redis:
pkill redis

启动redis:
cd /usr/local/redis/cluster/16001 && sh start.sh

master redis清理缓存：
/usr/local/redis/src/redis-cli -c -h 10.104.120.59 -p 16001 -a 666666
flushall

查看所有的key：
keys *

查看key被分配的槽号（slot号）：
cluster keyslot "CWgetNameByValueDM_GY_SWJG13502000000"

redis 版本查询：
     /usr/local/redis/src/redis-server --version
或者 /usr/local/redis/src/redis-server -v
或者 /usr/local/redis/src/redis-cli --version
或者 /usr/local/redis/src/redis-cli -v

查看集群状态：
cluster info

查看集群节点：
cluster nodes

新增节点加入到集群,默认主节点
cluster meet 127.0.0.1 7000  

将当前节点设置为node_id的从节点：
CLUSTER REPLICATE <node_id>   
  
将节点配置保存到磁盘：
cluster saveconfig  
            
从集群中移除指定节点,其他节点还是可以看到,只是不会存数据了：
CLUSTER FORGET <node_id>   

分配槽(slot)：
for i in {10923..16383};do redis-cli -c -h 127.0.0.1 -p 7000 CLUSTER ADDSLOTS $i>/dev/null;done
