修改Redis相关配置

Redis默认只允许本地访问，若要redis可以远程访问，得先修改redis.conf中的配置。
（若是windows环境下，该配置文件名称为 redis.windows-service.conf）

在redis安装目录下找到redis.conf文件并打开

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

# 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.
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 bind 127.0.0.1 -::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.

把这一行bind 127.0.0.1 -::1注释掉
此外，若是新版本（3.2之后）的还得修改一下redis的保护模式，同在redis.conf文件下

# 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

这里把protected-mode yes改为protected-mode no即可。

测试Redis远程访问

windows下：

Administrator@MICRO-911300019 C:\Users\Administrator
# redis-cli -h 192.168.190.5 -p 6379 -a 123456
192.168.190.5:6379> select 1
OK
192.168.190.5:6379[1]>

linux下：

[root@localhost ~]# redis -h 192.168.190.5 -p 6379 -a 123456
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.
192.168.190.5:6379> 

Warning是提醒在命令上输入密码是不安全的。
