关于bind

################################## NETWORK #####################################

# By default, if no "bind" configuration directive is specified, Redis listens
# for connections from all the network interfaces available on the server.
#默认情况下，如果没有声明bind指令，Redis会监听服务器上所有可用的网络接口（网卡）上的连接。
# It is possible to listen to just one or multiple selected interfaces using
# the "bind" configuration directive, followed by one or more IP addresses.
#可以用bind指令指定Redis监听的一个或多个网络接口（网卡），示例如下：
#
# Examples:
#
#bind 192.168.10.3 192.160.10.4 127.0.0.1
# 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
#如果你的Redis部署在公网上，并且监听所有网络接口（网卡），那么你的Redis示例便暴露给了互联网上的每个人，这样是很危险的。
# 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

• 意思是说 bind 指定是Redis所在服务器网卡的ip，不是指定某些IP可以访问本机Redis实例
• 如果你的bind指定的不是本机网卡IP，那么可能导致你的Redis实例无法启动

如何限制或指定IP访问呢？

1. 如果是内网访问，通过网络接口（网卡）限定，让客户端访问固定网卡连接redis
2. 如果是公网，通过iptables指定某个IP允许访问！！

总之，通过bind是无法指定某个IP来访问redis的。这在网上是一个很大的误区！！
