安装

Linux

安装参考https://openresty.org/cn/linux-packages.html，例如Ubuntu安装方式如下

# 安装导入 GPG 公钥时所需的几个依赖包（整个安装过程完成后可以随时删除它们）：
sudo apt-get -y install --no-install-recommends wget gnupg ca-certificates
# 导入我们的 GPG 密钥：
wget -O - https://openresty.org/package/pubkey.gpg | sudo apt-key add -
# 安装 add-apt-repository 命令
# （之后你可以删除这个包以及对应的关联包）
sudo apt-get -y install --no-install-recommends software-properties-common
# 添加我们官方 official APT 仓库：
sudo add-apt-repository -y "deb http://openresty.org/package/ubuntu $(lsb_release -sc) main"
# 更新 APT 索引：
sudo apt-get update
然后就可以像下面这样安装软件包，比如 openresty：
sudo apt-get -y install openresty

macOS

推荐使用brew

brew install openresty/brew/openresty

启动方式

To have launchd start openresty/brew/openresty now and restart at login:
  brew services start openresty/brew/openresty
Or, if you don't want/need a background service you can just run:
  openresty

docker

官方地址https://github.com/openresty/docker-openresty

$ docker run -d --name openresty -p80:80 openresty/openresty

访问http://localhost/

如果需要配置自定义的docker-compose

version: "3.7"
services:
  web:
    image: openresty/openresty
    container_name: openresty
    ports:
      - "80:80"
    volumes:
      - ./nginx.conf:/usr/local/openresty/nginx/conf/nginx.conf

默认的配置文件

worker_processes  auto;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    # See Move default writable paths to a dedicated directory (#119)
    # https://github.com/openresty/docker-openresty/issues/119
    client_body_temp_path /var/run/openresty/nginx-client-body;
    proxy_temp_path       /var/run/openresty/nginx-proxy;
    fastcgi_temp_path     /var/run/openresty/nginx-fastcgi;
    uwsgi_temp_path       /var/run/openresty/nginx-uwsgi;
    scgi_temp_path        /var/run/openresty/nginx-scgi;
    sendfile        on;
    keepalive_timeout  65;
    include /etc/nginx/conf.d/*.conf;
}

helloworld

修改配置文件如下

events {
    worker_connections  1024;
}
http {
    server {
        listen 80;
        location / {
            content_by_lua '
                ngx.say("hello, lua")
            ';
        }
    }
}
