Redis：连接报错

报错信息为

Error: 远程主机强迫关闭了一个现有的连接。或者 Error: 你的主机中的软件中止了一个已建立的连接。

在远程Redis服务及中连接redis正常，但是在客户机上连接时态。

解决方法是关闭protected-mode，并且开放所有端口的访问0.0.0.0。

当然，实际/生产情况或许并不建议你这么做，但是对于我的提供Redis服务的虚拟机而言，并没有什么问题。

原因在Redis的配置模板中有写

# 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.

所以对于我在客户机上连接失败的原因就是我没有设置密码，开启了protected_mode,并且还尝试从互联网上访问（虽然并不是互联网）
