Trojan 代理

Trojan 原生项目 在很多 Linux 发行版的包管理可以直接找到，如 Debian，服务端和客户端都执行：

apt install -y trojan

依赖的服务

选择 Trojan 就是因为其信息加密，不会像原生 VMess 协议那样只有内容加密，所以需要有域名和证书。

获取免费的域名可以参考 免费域名。获取免费的证书可以参考 免费 CDN。

如果是用 Cloudflare 的 nameservers，那么要注意 DNS Record 的 Proxy Status 只是 DNS only。因为原生 Trojan 不支持 SSL/TLS 的 Proxy。

服务端配置

将 pem 格式的公钥 xxx.crt 和私钥 xxx.key 保存到服务器，然后打开 /etc/trojan/config.json：

{
    "run_type": "server",
    "local_addr": "0.0.0.0",
    "local_port": 443,
    "remote_addr": "127.0.0.1",
    "remote_port": 80,
    "password": [
        "password1",
        "password2"
    ],
    "log_level": 1,
    "ssl": {
        "cert": "/path/to/xxx.crt",
        "key": "/path/to/xxx.key",
        "key_password": "",
        "cipher": "ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384",
        "cipher_tls13": "TLS_AES_128_GCM_SHA256:TLS_CHACHA20_POLY1305_SHA256:TLS_AES_256_GCM_SHA384",
        "prefer_server_cipher": true,
        "alpn": [
            "http/1.1"
        ],
        "alpn_port_override": {
            "h2": 81
        },
        "reuse_session": true,
        "session_ticket": false,
        "session_timeout": 600,
        "plain_http_response": "",
        "curves": "",
        "dhparam": ""
    },
    "tcp": {
        "prefer_ipv4": false,
        "no_delay": true,
        "keep_alive": true,
        "reuse_port": false,
        "fast_open": false,
        "fast_open_qlen": 20
    },
    "mysql": {
        "enabled": false,
        "server_addr": "127.0.0.1",
        "server_port": 3306,
        "database": "trojan",
        "username": "trojan",
        "password": "",
        "key": "",
        "cert": "",
        "ca": ""
    }
}

其实也就配置几个字段：

• local_port 配置对外端口
• password 配置密码
• ssl 的 cert 配置公钥位置，key 配置私钥位置

客户端配置

将服务端配置的公钥也保存到本地位置，然后打开 /etc/trojan/config.json：

{
    "run_type": "client",
    "local_addr": "127.0.0.1",
    "local_port": 1080,
    "remote_addr": "example.com",
    "remote_port": 443,
    "password": [
        "password1"
    ],
    "log_level": 1,
    "ssl": {
        "verify": true,
        "verify_hostname": true,
        "cert": "",
        "cipher": "ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-SHA:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES128-SHA:ECDHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA:AES128-SHA:AES256-SHA:DES-CBC3-SHA",
        "cipher_tls13": "TLS_AES_128_GCM_SHA256:TLS_CHACHA20_POLY1305_SHA256:TLS_AES_256_GCM_SHA384",
        "sni": "",
        "alpn": [
            "h2",
            "http/1.1"
        ],
        "reuse_session": true,
        "session_ticket": false,
        "curves": ""
    },
    "tcp": {
        "no_delay": true,
        "keep_alive": true,
        "reuse_port": false,
        "fast_open": false,
        "fast_open_qlen": 20
    }
}

客户端也是只需要配置几个字段：

• local_port 本地提供的 socks5 代理端口
• remote_addr 服务端的域名
• remote_port 服务端的端口
• password 服务端配置的密码
• ssl 的 cert 配置本地公钥位置
