Xray科学上网简要

在中国大陆,科学上网的需求对于技术人员,或者特定人群,始终是存在的。从最开始的 vpn 到 shadowsocks,再到 v2ray,最新的为 xray,包括其它的,目的都是为了自由访问互联网,获取必要资讯。 本文介绍在 linux pc 环境下,命令行模式科学上网配置, 非 GUI 外部依赖少,不需要等其它软件更新,即可获得最新功能,mac 应该也可以类似操作,但 mac 软件生态较好,一般下载对应的 app 安装即可,不要手动配置。

1. 购买海外主机

建议日本/新加坡/美西,或者香港主机,看云服务商,自己测试下速度,选速度快晚高峰不卡顿的

2. 服务端配置

  • xray github 仓库下载最新的平台软件包
  • 解压软件包到自定义目录, 我选择的目录为/opt/xray, 如下所示,config.json 为稍后创建的配置文件,其它 4 个为压缩包默认提供,无需更改
 1root@tokyo:~# ls -al /opt/xray/
 2total 40188

10-rwxr-xr-x 1 root root 20606976 Jan  1 08:00 xray
  • 使用 vim 或者 vscode 等编辑器配置 config.json 文件
 1root@tokyo:~# cat /opt/xray/config.json
 2{
 3    "log": {
 4    "access": "/var/log/xray/access.log",

21        ],

23        "fallbacks": [
24            {
25            "dest": 80
26            }
27        ]
28        },
29        "streamSettings": {
30        "network": "tcp",
31        "security": "xtls",
32        "xtlsSettings": {
33            "alpn": [
34            "http/1.1"
35            ],
36            "certificates": [
37            {
38                "certificateFile": "/root/.acme.sh/mephisto.cc/fullchain.cer",   # 改成你的证书
39                "keyFile": "/root/.acme.sh/mephisto.cc/mephisto.cc.key"  # 改成你的key
40            }
41            ]
42        }
43        }
44    }
45    ],
46    "outbounds": [
47    {
48        "protocol": "freedom"
49    }
50    ]
51}

mephisto.cc 是我购买的域名,证书部分由 caddy2 自动搞定,找到证书地址填到上面对应行即可, 无域名的配置方式,请参考 xray 的相关文档

  • systemd 配置,不会操作的搜索学习下,结果如下

    • 文件路径在这里/lib/systemd/system/xray.service

    • 进程监听状态确认, xray 的 444 端口已经开启监听,这个端口是上面配置的

      1    root@tokyo:~# ss -lntp |grep xray
      2    LISTEN 0      4096               *:444             *:*    users:(("xray",pid=2403220,fd=3))
      

    至此,服务端相关配置完成

3. 客户端配置,linux 命令行客户端配置, 和服务端相差不大,只是配置文件 config.json 内容不同

routing 和 dns 部分看起来复杂,请查看 xray 的文档,普通用户都不需要怎么改动,翻墙够用了

有人可能要问了,接下来怎么使用呢,操作很简单,我平时用两个浏览器,chrome 主力,firefox 配置上面的上述两种代理即可 setting/General/Network Settings/Settings/Manual proxy configration 下图所示

firefox proxy

另外,Gnome 等桌面也有全局网络代理设置,chrome 和 firefox 有相关代理插件可用,终端里面也可以配置环境变量的方式使用,不一一列举。

最后,特别说明手机端 ios 去美区下载 Shadowrocket 也可以配置使用
