新手问题 如何判断生产环境下 Nginx 是否正常工作
最近瞎摸了一下 nginx+passenger 在阿里云部署生产环境
项目下敲命令 passenger start -e production -d 也跑起来了
但是 nginx.conf 里写的用 80 端口。查的时候 80 端口是阿里云的服务在占用
所以不明白 nginx 是否有在工作，也有用命令去看进程
nginx.conf
server {
listen 80;
server_name ip;
root /root/project/public
passenger_enabled on;
location / {
root html;
index index.html index.htm;
}
}
lsof -i:80
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME

意思就是用在了 3000 端口上？
增加一个 /status
server {
location /status {
access_log off;
add_header Content-Type text/plain;
return 200 'OK via Nginx';
}
}
然后用 HTTP 访问 http://localhost/status 来验证
