如何验证 nginx 是否正在运行？

在我的本地机器上运行 运行 ASP.NET vNext 项目之后，我试图弄清楚如何在 Nginx上运行它，因为它看起来像 推荐选择

在 Jsinh 的 博客之后，我使用以下方法安装它:

sudo apt-get update
sudo apt-get install nginx -y

我试图通过使用以下方法来了解它是否有效:

ifconfig eth0 | grep inet | awk '{ print $2}'

跑完之后

sudo service nginx start
sudo service nginx stop

然而，输出总是相同的:

Nginx status

Not sure which guide you are following, but if you check out this page,

https://www.digitalocean.com/community/tutorials/how-to-install-nginx-on-ubuntu-14-04-lts

It uses another command 

ip addr show eth0 | grep inet | awk '{ print $2; }' | sed 's/\/.*$//'

and also indicates what result is expected.

You could use lsof to see what application is listening on port 80:

sudo lsof -i TCP:80

Looking at the requirement you have, the below command shall help:

service nginx status

None of the above answers worked for me so let me share my experience. I am running nginx in a docker container that has a port mapping (hostPort:containerPort) - 80:80 The above answers are giving me strange console output. Only the good old 'nmap' is working flawlessly even catching the nginx version. The command working for me is:

 nmap -sV localhost -p 80

We are doing nmap using the -ServiceVersion switch on the localhost and port: 80. It works great for me.

This is probably system-dependent, but this is the simplest way I've found.

if [ -e /var/run/nginx.pid ]; then echo "nginx is running"; fi

That's the best solution for scripting.

Can also use the following code to check the nginx status:

   sudo /etc/init.d/nginx status

The modern (systemctl) way of doing it:

systemctl is-active nginx

You can use the exit value in your shell scripts as follows:

systemctl -q is-active nginx && echo "It is active, do something"

If you are on mac machine and had installed nginx using 

brew install nginx

then 

brew services list

is the command for you. This will return a list of services installed via brew and their corresponding status.

The other way to see it in windows command line :

tasklist /fi "imagename eq nginx.exe"

INFO: No tasks are running which match the specified criteria.

if there is a running nginx you will see them

For Mac users

I found out one more way: You can check if /usr/local/var/run/nginx.pid exists. If it is - nginx is running. Useful way for scripting.

Example:

if [ -f /usr/local/var/run/nginx.pid ]; then
echo "Nginx is running"


fi

service nginx status will work on a non-systemd based version.

On systemd based versions such as Ubuntu Linux 16.04 LTS and above, make use of the command below;

systemctl status nginx
