port 6379

daemonize yes

pidfile /var/run/redis_6379.pid

logfile "/usr/local/redis-6.0.9/my_redis_tools/redis-6379.log"

dbfilename dump-6379.rdb

dir /usr/local/redis-6.0.9/my_redis_tools/

# 设置连接密码
requirepass foobared

iptables：未运行防火墙。
开启防火墙：
[root@centos6 ~]# service iptables start
关闭防火墙：
[root@centos6 ~]# service iptables stop
​

查看防火墙状态： 
firewall-cmd --state
关闭防火墙
systemctl stop firewalld.service
开启防火墙
systemctl start firewalld.service
禁用防火墙

2.4 工具连接

(1) redis-desktop-manager

(2) redis plus

2.5 工具使用

(1) redis-desktop-manager

key值使用:分隔，例如student:name,student:age，可以实现文件夹层级

(2) redis plus

没有实现key值文件夹层级

2.6 连接集群

2.6.1 新建文件夹

[root@localhost redis-6.0.9]# mkdir redis_cluster
[root@localhost redis-6.0.9]# cd redis_cluster/
[root@localhost redis_cluster]# pwd
/usr/local/redis-6.0.9/redis_cluster

2.6.2 准备服务端程序

复制redis-server和redis-cli文件

-rwxr-xr-x. 1 root root 8.7M Dec  9 20:59 redis-server
[root@localhost redis_cluster]#

2.6.3 准备6个redis的配置文件

创建文件夹，配置redis.conf文件
