# Linux Server Toolkit (Bash)
|
||
|
||
> 一组面向 Linux 服务器日常运维的 Bash 工具脚本。
|
||
> 仓库内每个子目录都是独立工具,可单独使用、单独维护。
|
||
|
||

|
||

|
||

|
||
|
||
## 项目定位
|
||
|
||
这个仓库用于集中管理常见服务器管理脚本,目标是:
|
||
|
||
- 开箱即用:脚本直接运行,不依赖复杂框架。
|
||
- 功能解耦:每个目录一个工具,互不耦合。
|
||
- 运维友好:输出清晰、彩色提示、错误处理明确。
|
||
- 可维护:脚本整体遵循统一 Bash 规范(见 `AGENTS.md`)。
|
||
|
||
适用场景:
|
||
|
||
- 新服务器初始化与巡检
|
||
- Docker / Systemd 状态排查
|
||
- 端口占用与服务健康检查
|
||
- 辅助部署 FRP、OpenList、FileBrowser 等服务
|
||
|

## 快速开始
|
||
|
||
### 1) 克隆仓库
|
||
|
||
```bash
|
||
git clone <your-repo-url>
|
||
cd bash
|
||
```
|
||
|
||
### 2) 运行任意脚本
|
||
|
||
```bash
|
||
# 方式 A:直接用 bash
|
||
bash path/to/script.sh
|
||
|
||
# 方式 B:赋予可执行权限后运行
|
||
chmod +x path/to/script.sh
|
||
./path/to/script.sh
|
||
|
||
# 方式 C:需要管理员权限时
|
||
sudo bash path/to/script.sh
|
||
```
|
||
|
||
### 3) 推荐先做语法检查
|
||
|
||
```bash
|
||
bash -n path/to/script.sh
|
||
```
|
||
|
||
## 核心工具使用示例
|
||
|
||
### 端口信息
|
||
|
||
```bash
|
||
bash port-info/port_info.sh
|
||
```
|
||
|
||
输出重点:TCP/UDP 监听端口、常见服务名映射(HTTP/HTTPS/MySQL/SSH 等)。
|
||
|
||
### Docker 信息
|
||
|
||
```bash
|
||
bash docker-info/docker-info.sh
|
||
```
|
||
|
||
输出重点:容器、镜像、网络、卷,以及主机基础状态。
|
||
|
||
### Systemctl 诊断
|
||
|
||
```bash
|
||
sudo bash systemctl-info/systemctl-info
|
||
```
|
||
|
||
输出重点:
|
||
|
||
- Systemd 版本与状态
|
||
- 失败服务与被屏蔽服务
|
||
- Timer/Socket/Target/Mount/Path/Device 单元
|

|
||
|
||
## 依赖与兼容性
|
||
|
||
### 基础依赖
|
||
|
||
- Linux(Ubuntu / Debian / CentOS 等)
|
||
- Bash 4.0+
|
||
- 常见系统工具:`awk` `grep` `sed` `sort` `uniq`
|
||
|
||
### 按工具可选依赖
|
||
|
||
- 端口工具:`ss` 或 `netstat`
|
||
- Docker 工具:`docker`
|
||
- Systemd 工具:`systemctl` `journalctl`
|
||
- 推荐安装:`shellcheck`(静态检查)
|
||
|
||
## 开发与质量检查
|
||
|
||
仓库是 Bash 脚本项目,没有编译步骤,建议最少执行以下检查:
|
||
|
||
```bash
|
||
# 语法检查
|
||
bash -n port-info/port_info.sh
|
||
|
||
# 静态检查
|
||
shellcheck port-info/port_info.sh
|
||
shellcheck docker-info/docker-info.sh
|
||
shellcheck systemctl-info/systemctl-info
|
||
```
|
||
|
||
批量检查示例:
|
||
|
||
```bash
|
||
for f in **/*.sh; do
|
||
bash -n "$f" || exit 1
|
||
done
|
||
```
|
||
|
||
更多开发约束请参考根目录 `AGENTS.md`。
|
||
|
||
## 常见问题
|
||
|
||
### 1) 提示 `ss` 或 `netstat` 不存在
|
||
|
||
```bash
|
||
sudo apt-get update
|
||
sudo apt-get install -y net-tools iproute2
|
||
```
|
||
|
||
### 2) Docker 信息脚本运行失败
|
||
|
||
- 确认 Docker 已安装并运行:`systemctl status docker`
|
||
- 确认当前用户有权限访问 Docker socket(或直接使用 `sudo`)
|
||
|
||
### 3) `systemctl-info` 信息不完整
|
||
|
||
- 请使用 root 权限运行:`sudo bash systemctl-info/systemctl-info`
|
||
|
||
## 安全说明
|
||
|
||
- 本仓库部分脚本会执行安装、服务管理、系统配置修改操作。
|
||
- 请先阅读对应脚本内容,再在生产环境执行。
|
||
- 不要在不可信环境中直接运行来源不明脚本。
