redis.conf详解之bind

用法

绑定到本机的其中一个ip

bind 2.2.2.2 

绑定到本机的两个ip，如果10.0.0.1无效redis依旧可以启动。

bind 192.168.1.100 -10.0.0.1

绑定到本机的ipv6

bind ::1

用途

bind用于绑定本机的网络接口（网卡），redis只接受来自绑定网络接口的请求。
比如本机有两个网卡分别对应ip 1.1.1.1 ,2.2.2.2，配置bind 1.1.1.1，客户端288.30.3.3访问2.2.2.2将无法连接redis。

注意事项

如果不配置bind，redis将监听本机所有可用的网络接口。
不配置指：redis.conf中无bind配置、#bind 127.0.0.1。

- 当指定的网络接口不可用且其他网络接口可用时，不会启动失败。
当17.0.0.1为无效ip，127.0.0.1为有效ip。以下配置以及log输出。

bind -17.0.0.1
// Warning: Could not create server TCP listening socket 17.0.0.1:6379: bind: Can't assign requested address
// Configured to not listen anywhere, exiting.

bind -17.0.0.1 127.0.0.1
// Warning: Could not create server TCP listening socket 17.0.0.1:6379: bind: Can't assign requested address
// ···省略···
// Ready to accept connections

原生注释

# By default, if no "bind" configuration directive is specified, Redis listens
# for connections from all available network interfaces on the host machine.
# It is possible to listen to just one or multiple selected interfaces using
# the "bind" configuration directive, followed by one or more IP addresses.
# Each address can be prefixed by "-", which means that redis will not fail to
# start if the address is not available. Being not available only refers to
# addresses that does not correspond to any network interfece. Addresses that
# are already in use will always fail, and unsupported protocols will always BE
# silently skipped.
#
# Examples:
#
# bind 192.168.1.100 10.0.0.1     # listens on two specific IPv4 addresses
# bind 127.0.0.1 ::1              # listens on loopback IPv4 and IPv6
# bind * -::*                     # like the default, all available interfaces
#
# ~~~ 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 on the
# IPv4 and IPv6 (if available) loopback interface addresses (this means Redis
# will only be able to accept client connections from the same host that it is
# running on).
#
# IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES
# JUST COMMENT OUT THE FOLLOWING LINE.
