redis遠端連線
redis 遠端連線方法
解決方法
1、修改redis伺服器的配置檔案
vi redis.conf
註釋以下繫結的主機地址
# bind 127.0.0.1
或
vim redis.conf
bind 0.0.0.0
protected-mode no
2、修改redis伺服器的引數配置
修改redis的守護程序為no，不啟用
127.0.0.1:6379> config set daemonize "no"
OK
修改redis的保護模式為no，不啟用
127.0.0.1:6379> config set protected-mode"no"
OK
或者
config set requirepass 123 ->123是密碼
注意：開啟 6379埠
3、遠端連線
$ redis-cli -h 138.138.138.138 -p 6379
redis>ping
PONG

如何讓Redis允許遠端連線，並設定密碼
最近網站資料量過大，需要在資料庫上層增加一個快取層，所以採用了Redis作為資料庫。但是Redis預設是不允許遠端連線的，主要還是考慮到了安全問題。
但是如果需要遠端連線，那該如何操作呢：
在/etc/redis/redis.conf檔案裡面修改如下配置檔案，
################################## 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 ::1
將bind 127.0.0.1 ::1註釋掉：
# bind 127.0.0.1 ::1
這樣就可以遠端連線了。
允許遠端連線就帶來了一個很大的問題，可以用過網際網路破解Redis密碼，所以需要設定Redis的密碼。
redis的查詢速度是非常快的，外部使用者一秒內可以嘗試多大150K個密碼；所以密碼要儘量長（對於DBA 沒有必要必須記住密碼）；
所以需要設定一個很長的密碼，防止破解。
找到剛才的配置檔案，有如下內容：
################################## SECURITY ###################################
# Require clients to issue AUTH before processing any other # commands. This might be useful in environments in which you do not trust # others with access to the host running redis-server. # # This should stay commented out for backward compatibility and because most # people do not need auth (e.g. they run their own servers). # # Warning: since Redis is pretty fast an outside user can try up to # 150k passwords per second against a good box. This means that you should # use a very strong password otherwise it will be very easy to break. # requirepass xxxxxxxxxxxx
修改requirepass 後面就是密碼，密碼設定的儘量長。
之後重啟Redis，在真正的專案上，需要注意資料的持久化，否則重啟資料會丟失。
如果是用apt-get或者yum install安裝的redis，可以直接通過下面的命令停止/啟動/重啟redis
/etc/init.d/redis-server stop
/etc/init.d/redis-server start
/etc/init.d/redis-server restart
如果是通過原始碼安裝的redis，則可以通過redis的客戶端程式redis-cli的shutdown命令來重啟redis
1、Redis關閉：
redis-cli -h 127.0.0.1 -p 6379 shutdown
2、Redis啟動：
redis-server
