Nintendo Switch 联网加速的一种姿势

最近 switch 上有了狂野飙车，但是在酒店的网络死活连不上。刚好朋友的 switch 想用舞力全开 unlimited 也不行，就天天试着各种方法。

开始就想着花钱用各种加速器，但是出差只带了公司的电脑，各种限制，电脑上开了各种加速器之后，根本没法共享给 switch然后转战淘宝，发现有卖代理服务器的，就是给你个 IP+Port，先买个 1 块的试了试，下东西是很快，但是还是没法登陆狂野飙车，顺便看了下卖家给的服务器 IP 是美帝的。

然后想着能不能找个香港的服务器会好些，于是刚刚自己买了个阿里云国际的轻应用服务器，3.5$,搭建好之后，NAT 类型变成了 B，测速是 20Mbps 左右，几个朋友一起用，还是很合算的。

下面写下搭建过程，希望能帮得上有需要的人。如果有啥写错的，请轻喷~

#教程基于 CentOS

1.安装 Squid 并修改配置：

yum install squid -y cp /etc/squid/squid.conf /etc/squid/squid.conf.bak vi /etc/squid/squid.conf 

我的配置文件，主要是修改端口和添加认证信息：

# # Recommended minimum configuration: # # Example rule allowing access from your local networks. # Adapt to list your (internal) IP networks from where browsing # should be allowed acl localnet src 10.0.0.0/8 # RFC1918 possible internal network acl localnet src 172.16.0.0/12 # RFC1918 possible internal network acl localnet src 192.168.0.0/16 # RFC1918 possible internal network acl localnet src fc00::/7 # RFC 4193 local private network range acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines acl SSL_ports port 443 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl CONNECT method CONNECT # # Recommended minimum Access Permission configuration: # # Deny requests to certain unsafe ports #http_access deny !Safe_ports # Deny CONNECT to other than secure SSL ports #http_access deny CONNECT !SSL_ports # Only allow cachemgr access from localhost http_access allow localhost manager http_access deny manager # We strongly recommend the following be uncommented to protect innocent # web applications running on the proxy server who think the only # one who can access services on "localhost" is a local user #http_access deny to_localhost # # INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS # # Example rule allowing access from your local networks. # Adapt localnet in the ACL section to list your (internal) IP networks # from where browsing should be allowed #http_access allow localnet http_access allow localhost # And finally deny all other access to this proxy #http_access deny all # Squid normally listens to port 3128 #http_port 3128 # Uncomment and adjust the following to add a disk cache directory. #cache_dir ufs /var/spool/squid 100 16 256 # Leave coredumps in the first cache dir coredump_dir /var/spool/squid # # Add any of your own refresh_pattern entries above these. # refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 refresh_pattern . 0 20% 4320 #用户认证文件的位置 auth_param basic program /usr/lib64/squid/basic_ncsa_auth /etc/squid/passwd auth_param basic realm proxy acl authenticated proxy_auth REQUIRED http_access allow authenticated #http 代理的端口，默认为 3128 http_port 12306 acl OverConnLimit maxconn 16 #定义每个 IP 最大允许 16 个连接，防止攻击 

2.然后配置用户，为了安全：

先安装 httpd

yum install httpd* -y 

添加用户：

htpasswd -c /etc/squid/passwd <username> #然后输入密码。 

重启 Squid 并启用开机启动：

systemctl restart squid systemctl enable squid 

3.测试:

先在 VPS 上本地测试下：

curl --proxy 127.0.0.1:PORT --proxy-user <username>:<password> http://www.baidu.com 

如果有返回的话，应该就是 OK 了。

然后可以从其它 Linux 上测试下，记得在 VPS 管理的地方防火墙放通自己定义的 PORT：

curl --proxy <服务器 IP>:PORT --proxy-user <username>:<password> http://www.baidu.com 

然后 Switch 只需要在连接 wifi 的地方配置好代理服务器 IP + PORT + User + Password,就能用了。

不保证每个地区都好用，具体的网络还是跟当地的情况有很大关系。阿里云这个机器带宽是 30M,我现在在杭州，网络是电信，测速有 20Mbps 左右，sShop 下载的时候，从服务器侧看，带宽跑到 17M 左右；朋友在重庆，测速只有 6Mbps，但是可以正常缓冲出舞力全开的在线歌曲。

Ps.也欢迎大家讨论其他更好用的方法。
