caddy

安装篇(centos7)

sudo yum install yum-plugin-copr -y
sudo yum copr enable @caddy/caddy -y
sudo yum install caddy -y

caddy是因为插件得扩展,扩展插件好用得原因不像nginx重新下载源码编译那么麻烦

直接访问https://caddyserver.com/download 然后鼠标可以选中要用得插件直接下载二进制替换即可

cp $(which caddy) $(which caddy)_$(caddy_v2.5.0 version |awk '{print$1}')
mv caddy_v2.5.0-rc.1 $(which caddy)

caddy常用命令

# 检查配置
caddy validate
# 重载配置
caddy reload
# 停止
caddy stop
# 查看模块
caddy list-modules
# 生成一条命令
caddy adapt --config caddy.yaml --adapter yaml
# 验证 Caddyfile 有效性
caddy adapt --config ./Caddyfile --validate
# 格式化配置
caddy fmt
caddy fmt -overwrite Caddyfile
# 启动测试
caddy run -config /etc/caddy/Caddyfile

caddy配置(列举一些常用得demo) 配置路径 /etc/caddy/Caddyfile

1.做个获取公网ip得api


http://ip.1nth.com:80 https://ip.1nth.com {
	respond / 200 {
		body "{remote_host}
"
	}
}

2.使用阿里云ack自动获取证书

*.1nth.com {
	tls {
		dns alidns {
			access_key_id "access_key_id"
			access_key_secret "access_key_secret"
		}
	}
	import LOG "/var/log/caddy/caddy.log"
}

3.静态文件

:80 {
        root * /var/www/html
        file_server
}

4.目录列表服务(说白了就是文件服务器)

:88 {
        root * /opt
        file_server browse
}


:88 {
	route /files/* {
		#redir /myki /
                uri strip_prefix /files
		root * /opt
		file_server browse
	}
}

5.同时映射多个地址

localhost:8888,
psvmc.cn,
www.psvmc.cn {
	root * /data/myblog
	tls /etc/caddy/cert/psvmc.pem /etc/caddy/cert/psvmc.key
	file_server
}

6.重定向(http跳转https)

www.1nth.com {
    redir https://1nth.com{uri} permanent
}

7.负载均衡 反向代理

www.1nth.com {
	reverse_proxy localhost:9000 localhost:9001 {
		lb_policy first
	}
}

8.Websocket反向代理

ws.1nth.com {
  ## HTTP 代理配置
  ## 此时访问 ws.1nth.com，实际访问的是 127.0.0.1:8080/app/ 的内容
  reverse_proxy / 127.0.0.1:8080/app/

  ## WebSocket 代理配置
  ## 客户端请求的 wss://ws.1nth.com/ws, 实际为 wss://127.0.0.1:8080/ws
  reverse_proxy /ws 127.0.0.1:8080
}

9.跨域访问

:2020 {
    @options {
        method OPTIONS
    }
    header {
        Access-Control-Allow-Origin "{http.request.header.Origin}"
        Access-Control-Allow-Credentials true
        Access-Control-Allow-Methods *
        Access-Control-Allow-Headers DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization
    }
    reverse_proxy 127.0.0.1:8080
    respond @options 204
}

自己编译需要得模块caddy (Ubuntu 22.04)

# 安装go
sudo tar -zxvf go1.18.1.linux-amd64.tar.gz -C /usr/local/
# 配置go环境变量
mkdir -p ${HOME}/.go/{src,bin,pkg}
vi /etc/.bashrc
export GO111MODULE=on
export GOPROXY='https://goproxy.cn,direct'
export GOROOT=/usr/local/go
export GOPATH="${HOME}/.go"
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin


go version
go env -w GO111MODULE=on
go env -w GOPROXY=https://goproxy.cn,direct

# 安装 xcaddy
go install github.com/caddyserver/xcaddy/cmd/xcaddy@latest
# 安装完成后应当在命令行可以直接执行 xcaddy 命令
xcaddy version
# 编译之前系统需要安装 jq、curl、git
apt install -y curl git jq
# 获取最新版本号，其实直接去 GitHub realse 页复制以下就行
# 这里转化为脚本是为了方便自动化

#获取caddy2的最新版本号，并导入变量version
export version=$(curl -s "https://api.github.com/repos/caddyserver/caddy/releases/latest" | jq -r .tag_name)
#2.4.6编译报错  用最新版编译
export version=v2.5.0
# 使用 xcaddy 编译 https://jivps.com/21.html  https://mritd.com/2021/01/07/lets-start-using-caddy2/
# xcaddy build ${version} --output ./caddy_${version}
xcaddy build ${version} --output ./caddy_${version} \
