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

去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
 3drwxr-xr-x 2 root root     4096 Jun  3 17:07 .

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",
 5    "error": "/var/log/xray/error.log",
 6    "loglevel": "warning",
 7    "dnsLog": false
 8    },
 9    "inbounds": [
10    {

12        "protocol": "vless",
13        "settings": {
14        "clients": [
15            {
16            "id": "your_uuid", # 你的uuid，由xray uuid命令生成
17            "flow": "xtls-rprx-direct",
18            "level": 0,
19            "email": "[email protected]"
20            }
21        ],
22        "decryption": "none",
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

 1root@tokyo:~# systemctl status xray.service

开机启动检查

1root@tokyo:~# systemctl is-enabled xray.service
2enabled

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

验证是否符合预期

命令行 http 代理测试，it works!

socks5 代理测试，也是能工作的

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

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
