1. 安装V2Ray Core

# 安装依赖
sudo apt update && sudo apt install curl unzip -y

# 下载并执行官方安装脚本
bash <(curl -L https://raw.githubusercontent.com/v2fly/fhs-install-v2ray/master/install-release.sh)

2. 编写配置文件

输入指令: sudo vim /usr/local/etc/v2ray/config.json

日志配置：记录 warning 级别及以上的日志到 /var/log/v2ray/。

本地监听入口：

  • 端口 1080：SOCKS5 代理，支持 UDP 及流量嗅探
  • 端口 1081：HTTP 代理
  • 两个端口均只监听 127.0.0.1，不对外暴露

流量出口：

  • proxy：通过 VMess + WebSocket 协议连接远程代理服务器
  • direct：直连，不走代理

路由规则：私有 IP（局域网）走直连，其余流量走代理。

注意：以下 address、port、id、alterId、path、Host 需要替换为自己的节点信息。

{
  "log": {
    "loglevel": "warning",
    "access": "/var/log/v2ray/access.log",
    "error": "/var/log/v2ray/error.log"
  },
  "inbounds": [

      },
      "sniffing": {
        "enabled": true,
        "destOverride": ["http", "tls"]
      }
    },
    {

      "listen": "127.0.0.1",

    }

                "security": "auto"
              }
            ]
          }
        ]
      },
      "streamSettings": {
        "network": "ws",
        "wsSettings": {
          "path": "/your-path",
          "headers": {
            "Host": "your-server-address"
          }
        },
        "security": "none"
      },
      "tag": "proxy"
    },
    {
      "protocol": "freedom",
      "tag": "direct"
    }
  ],
  "routing": {
    "domainStrategy": "IPIfNonMatch",
    "rules": [
      {
        "type": "field",
        "ip": ["geoip:private"],
        "outboundTag": "direct"
      }
    ]
  }
}

3. 启动和管理V2Ray

# 重载 systemd 配置
sudo systemctl daemon-reload

# 启动 V2Ray
sudo systemctl start v2ray

# 设置开机自启
sudo systemctl enable v2ray

# 查看运行状态（检查是否正常启动）
sudo systemctl status v2ray
  • 测试代理是否可用
# 测试 HTTP 代理
curl --proxy http://127.0.0.1:1081 https://www.google.com

# 测试 SOCKS5 代理
curl --socks5 127.0.0.1:1080 https://www.google.com
  • 常用命令
# 停止
sudo systemctl stop v2ray

# 重启（修改配置后必须执行）
sudo systemctl restart v2ray

# 查看日志
sudo journalctl -u v2ray -f
  • 终端使用代理
# HTTP/HTTPS 代理
export http_proxy=http://127.0.0.1:1081
export https_proxy=http://127.0.0.1:1081

# 取消代理
unset http_proxy https_proxy

1. Ruby+Devkit安装

下载Ruby+Devikit的安装包rubyinstaller.org，使用默认选项进行安装

rubyinstaller.org

最后一步，不要勾选ridk install的选项，选择自己安装ridk

检查ruby是否安装成功:ruby -v

ruby -v

更换源: gem sources --add https://gems.ruby-china.com/ --remove https://rubygems.org/ 更换完成后， 使用指令gem sources -l确认是否成功。

安装 MSY32, 执行 ridk install, 执行后需要进行选择，直接选择3:

ridk install

安装结束后, 最后进行选择时, 直接回车即可:

ridk install

2. 安装Jekyll

输入指令: gem install bundler

输入指令: gem install jekyll
检查jekyll安装是否成功:
jekyll -v

3. 安装本项目及其依赖

git clone https://github.com/ZYCheng1002/ZYCheng1002.github.io
更改Gemfile中的source "https://gems.ruby-china.com/"为国内源
执行指令:
bundle install

等待安装完成后， 运行
bundle exec jekyll serve
在浏览器里打开 http://127.0.0.1:4000

注

Jekyll 要求博客文章文件按照以下格式命名:

YEAR-MONTH-DAY-title.MARKUP

Where YEAR is a four-digit number, MONTH and DAY are both two-digit numbers, and MARKUP is the file extension representing the format used in the file. After that, include the necessary front matter. Take a look at the source for this post to get an idea about how it works.
