網上很多，你應該已經查了一溜夠了！我這里只強調config 配置文件！
而配置里，兩個配置起決定性作用，bind屬性和protected-mode屬性（protected-mode有沒有是要看版本，老版本沒有的）。我為什么把注釋都放進來呢，因為人家已經寫得很清楚了，好好看！
################################## NETWORK ##################################### # By default, if no "bind" configuration directive is specified, Redis listens # for connections from all the network interfaces available on the server. # It is possible to listen to just one or multiple selected interfaces using # the "bind" configuration directive, followed by one or more IP addresses. # # Examples: # # bind 192.168.1.100 10.0.0.1 # bind 127.0.0.1 ::1 # # ~~~ WARNING ~~~ If the computer running Redis is directly exposed to the # internet, binding to all the interfaces is dangerous and will expose the # instance to everybody on the internet. So by default we uncomment the # following bind directive, that will force Redis to listen only into # the IPv4 lookback interface address (this means Redis will be able to # accept connections only from clients running into the same computer it # is running). # # IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES # JUST COMMENT THE FOLLOWING LINE. # ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ bind 127.0.0.1
# Protected mode is a layer of security protection, in order to avoid that # Redis instances left open on the internet are accessed and exploited. # # When protected mode is on and if: # # 1) The server is not binding explicitly to a set of addresses using the # "bind" directive. # 2) No password is configured. # # The server only accepts connections from clients connecting from the # IPv4 and IPv6 loopback addresses 127.0.0.1 and ::1, and from Unix domain # sockets. # # By default protected mode is enabled. You should disable it only if # you are sure you want clients from other hosts to connect to Redis # even if no authentication is configured, nor a specific set of interfaces # are explicitly listed using the "bind" directive. protected-mode yes
如果鏈接不上，我看很多都讓把 protected-mode 修改為 no 並且 將 bind屬性注釋掉 （老版本只注釋掉bind），但是，這樣，不就誰都可以鏈接redis數據庫了？那就不安全了啊
所以，protected-mode屬性根本不用改，bind屬性不要注釋，只需要在bind 后添加你想要鏈接此數據庫的地址就好了 如：
bind 192.168.1.100 10.0.0.1 就代表192.168.1.100和10.0.0.1是可以鏈接到數據庫的，人家寫的很清楚了！而且這也是安全並被推薦使用的！
下面說一下windows 下啟動redis服務的問題！
如下圖，是windows安裝完的文件
通常，我們會雙擊redis-server.exe啟動服務，但是默認服務使用的並不是這里的conf配置文件，如圖：
這個/path/to/redis.conf才是redis-server.exe啟動時指定的redis.conf配置,理論上我們修改這個redis.conf里的屬性，重新啟動服務也行，然而，我並沒找到這個redis.conf
所以我修改了redis.windows-service.conf 配置（當然你可以修改redis.windows.conf我認為也沒問題），並指定修改好的配置文件 如：
這時候再啟動redis-cli.exe 運行命令：config get * 查看一下你的conf配置就ok了
至於linux下，如果鏈接不上redis也是這個思路：修改下配置文件，然后指定配置文件重新啟動服務就好了！
redis-cli -h 127.0.0.1 -p 6379 shutdown
2.登錄redis：redis-cli -h 127.0.0.1 -p 6379
3.查看所有key值：keys *
4.刪除指定索引的值：del key
5.清空整個 Redis 服務器的數據：flushall
6.清空當前庫中的所有 key：flushdb
查詢redis
ps aux|grep redis
關閉redis服務
redis-cli shutdown
指定conf啟動redis-server
redis-server etc/redis/redis.conf
