-----------------------------跳过安装过程---------------------------------------
一、快速部署集群
1、 进入集群目录，创建集群
[root@localhost ~]# cd /usr/local/redis-6.2.12/utils/create-cluster
[root@localhost create-cluster]# ./create-cluster start
Starting 30001
Starting 30002
Starting 30003
Starting 30004
Starting 30005
Starting 30006
2、 查看正常启动
[root@localhost create-cluster]# netstat -pltun

3、停止redis进程

三、手动部署集群
1、配置redis.conf配置文件
[root@localhost redis]# cd /usr/local/redis/
[root@localhost redis]# mkdir cluster
#创建6个redis.config文件
[root@localhost cluster]# vim redis-cluster-6379.conf
[root@localhost cluster]# vim redis-cluster-6380.conf
[root@localhost cluster]# vim redis-cluster-6381.conf
[root@localhost cluster]# vim redis-cluster-6382.conf
[root@localhost cluster]# vim redis-cluster-6383.conf
[root@localhost cluster]# vim redis-cluster-6382.conf
[root@localhost cluster]# vim redis-cluster-6384.conf
#里面内容如下，记得根据不同的配置文件修改文件里面的内容
root@localhost cluster]# cat redis-cluster-6379.conf
# 数据存储目录
# 指定 Redis 数据文件和配置文件的存储位置
dir "/usr/local/redis/cluster/db/6379"
# 启用集群模式
# 启用 Redis 集群功能，使该实例作为集群的一部分工作
cluster-enabled yes
# 集群配置文件
# 指定 Redis 集群的配置文件名，Redis 在运行时将存储集群状态
cluster-config-file 6379.conf
# 端口号
# 指定 Redis 实例监听的端口号
port 6379
# 守护进程模式
# 使 Redis 以守护进程方式运行，即在后台运行
daemonize yes
# 绑定 IP 地址
# 指定 Redis 监听的 IP 地址，0.0.0.0 表示监听所有网络接口
bind 0.0.0.0
# 密码保护
# 设置访问 Redis 实例所需的密码
#requirepass your_password_here
# 日志文件
# 指定 Redis 日志文件的存储位置
logfile "/usr/local/redis/cluster/logs/6379.log"
# 日志级别
# 指定日志记录的级别，可以是 debug、verbose、notice、warning
loglevel info
#创建目录
[root@localhost cluster]# mkdir db
[root@localhost cluster]# cd db/
[root@localhost db]# mkdir {6379,6380,6381,6382,6383,6384}
[root@localhost db]# ll
total 0
drwxr-xr-x. 2 root root 6 Jul 9 00:26 6379
drwxr-xr-x. 2 root root 6 Jul 9 00:26 6380
drwxr-xr-x. 2 root root 6 Jul 9 00:26 6381

drwxr-xr-x. 2 root root 6 Jul 9 00:26 6383
drwxr-xr-x. 2 root root 6 Jul 9 00:26 6384
2、启动redis集群
[root@localhost cluster]# ../../redis/bin/redis-server redis-cluster-6379.conf
[root@localhost cluster]# ../../redis/bin/redis-server redis-cluster-6380.conf[root@localhost cluster]# ../../redis/bin/redis-server redis-cluster-6381.conf
[root@localhost cluster]# ../../redis/bin/redis-server redis-cluster-6382.conf
[root@localhost cluster]# ../../redis/bin/redis-server redis-cluster-6383.conf
[root@localhost cluster]# ../../redis/bin/redis-server redis-cluster-6384.conf[root@localhost cluster]# ps -ef|grep redis
root 1847 1 0 00:32 ? 00:00:00 ../../redis/bin/redis-server *:6379 [cluster]
root 1852 1 0 00:32 ? 00:00:00 ../../redis/bin/redis-server *:6380 [cluster]

root 1842 1 0 00:32 ? 00:00:00 ../../redis/bin/redis-server *:6384 [cluster]
3、手动创建redis集群
