redis開啓遠程訪問

redis默認只容許本地訪問，要使redis能夠遠程訪問能夠修改redis.conf

打開redis.conf文件在NETWORK部分有說明

################################## 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

解決辦法：註釋掉bind 127.0.0.1能夠使全部的ip訪問redis 如果想指定多個ip訪問，但並非所有的ip訪問，能夠bind

注意 下面還有個說明

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

在redis3.2以後，redis增長了protected-mode，在這個模式下，即便註釋掉了bind 127.0.0.1，再訪問redisd時候仍是報錯，以下

(error) DENIED Redis is running in protected mode because protected mode is enabled, no bind address was specified, no authentication password is requested to clients. In this mode connections are only accepted from the loopback interface. If you want to connect from external computers to Redis you may adopt one of the following solutions: 1) Just disable protected mode sending the command 'CONFIG SET protected-mode no' from the loopback interface by connecting to Redis from the same host the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to 'no', and then restarting the server. 3) If you started the server manually just for testing, restart it with the '--protected-mode no' option. 4) Setup a bind address or an authentication password. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside.

修改辦法：protected-mode no
