This article introduces the relevant knowledge of "what to do if you fail to open nginx.pid". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

I. description of the problem

When we usually use nginx, it is often possible to find that our pid is missing and missing, which leads to an error, as follows:

Nginx: [error] open () "/ var/run/nginx/nginx.pid" failed (2: No such file or directory)

Or:

Nginx: [error] invalid PID number "" in "/ var/run/nginx/nginx.pid"

2. analysis of the emergence of problems

Nginx.pid file does not exist

The directory where nginx.pid is located does not exist.

Solution 1: create a directory

For the problem:

Try to enter the / var/run/nginx directory:

The directory configured by nginx.pid here is set when compiling nginx, so which directory to detect depends on what directory you set at compile time:

You can view it through: nginx-V instruction

If the directory is not found, create it:

Mkdir / var/run/nginx

Exactly where to create a directory here is also the same as above to see what directory you configured at compile time.

Try to enter the newly created directory and check that it has been created successfully:

Cd / var/run/nginx

Enter the directory where nginx is installed:

Cd / usr/local/nginx

Get the installation directory of nginx: whereis nginx

Scenario 2: reassign a profile

For the problem:

Enter sbin:

Cd / sbin

Reassign a nginx.conf file:

. / nginx-c / usr/local/nginx/conf/nginx.conf

Reload the configuration file

. / nginx-s reload scheme 3: modify the default pid

Enter the conf directory:

Cd.. / conf

Modify the nginx.conf file to execute the new nginx.pid:
