🎯 OpenClaw 项目概述

OpenClaw 是基于 Rust 语言构建的异步高性能 Web 框架，专为云原生环境设计。核心特性：

⚡ 极致性能

基于 tokio 异步运行时，零成本抽象，内存安全无GC。单机可承载10万+并发连接。

🔒 企业级安全

内置SQL注入防护、XSS过滤、CSRF令牌、速率限制，满足OWASP Top 10标准。

☁️ 云原生就绪

原生支持Prometheus metrics、健康检查、分布式追踪，适配K8s、EC2、Lighthouse。

💻 本地开发环境部署

1 获取源码

git clone https://github.com/openclaw/openclaw.git
cd openclaw
git checkout v1.2.0

2 配置环境变量

复制环境变量模板：

cp .env.example .env

编辑 .env 核心配置：

# 应用配置
APP_NAME=openclaw
APP_ENV=development
APP_HOST=0.0.0.0
APP_PORT=8080

# PostgreSQL 数据库
DATABASE_URL=postgres://openclaw:password@localhost:5432/openclaw

# Redis 缓存
REDIS_URL=redis://localhost:6379

# JWT 认证密钥
JWT_SECRET="$(openssl rand -base64 32)"

3 数据库迁移

# 安装 SQLx CLI
cargo install sqlx-cli --no-default-features --features native-tls,postgres

# 创建并迁移数据库
sqlx database create
sqlx migrate run

4 编译运行

# 开发模式（热重载）
cargo install cargo-watch
cargo watch -x run

# 生产编译
cargo build --release
./target/release/openclaw

✅ 验证部署： 访问 http://localhost:8080/health 应返回 {"status":"healthy"}

🐳 Docker 容器化部署

多阶段构建 Dockerfile

# 构建阶段
FROM rust:1.70-slim-bullseye AS builder
WORKDIR /app
COPY . .
RUN apt-get update && apt-get install -y pkg-config libssl-dev
RUN cargo build --release

# 运行阶段
FROM debian:bullseye-slim
RUN apt-get update && apt-get install -y ca-certificates libssl1.1 && rm -rf /var/lib/apt/lists/*
COPY --from=builder /app/target/release/openclaw /usr/local/bin/
ENV APP_ENV=production
EXPOSE 8080
CMD ["openclaw"]

Docker Compose 全栈部署

📊 监控与运维配置

Prometheus 指标集成

use prometheus::{Encoder, TextEncoder, register_counter, Counter};
use lazy_static::lazy_static;

lazy_static! {
    static ref HTTP_REQUESTS: Counter = register_counter!(
        "http_requests_total",
        "Total number of HTTP requests"
    ).unwrap();
}

async fn metrics_handler() -> impl Responder {
    let encoder = TextEncoder::new();
    let mut buffer = vec![];
    encoder.encode(&prometheus::gather(), &mut buffer).unwrap();
    
    HttpResponse::Ok()
        .content_type("text/plain; version=0.0.4")
        .body(buffer)
}

健康检查端点

端点	预期响应	用途
`/health`	200 + {"status":"healthy"}	K8s livenessProbe
`/ready`	200 + {"ready":true}	K8s readinessProbe
`/metrics`	200 + Prometheus格式	监控采集
`/version`	200 + {"version":"1.2.0"}	版本管理

🔧 常见故障排除

❌ 数据库连接池耗尽

现象： 日志中出现 pool timed out while waiting for connection

解决方案：

# 增加连接池大小
DATABASE_POOL_SIZE=30
DATABASE_TIMEOUT=30

# 启用连接重用
DATABASE_CONNECTIONS_MAX_LIFETIME="1800s"

❌ 内存持续增长

现象： RSS内存随请求量线性增加，不释放
