Depending on the kind of gateway you have you should use something like:

    proxy_read_timeout 600s;

Check docs: http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_read_timeout

If it is a `fastcgi` timeout error, then you need to increase the `fastcgi_read_timeout`.

```
# /etc/nginx/conf.d/example.com.conf
server {

    location ~ \.(php)$ {
        fastcgi_pass unix:/var/run/php74-example.com.sock;
        fastcgi_read_timeout 300s;
```


error log) upstream timed out

```
# tail -f example.com.error.log

What is the equivalent of apk in iOS?

I have two scripts 1.sh and 2.sh.

1.sh is as follows:

    #!/bin/sh
    variable=&quot;thisisit&quot;
    export variable

2.sh is as follows:

    #!/bin/sh
    echo $variable

According to what I read, doing like this (export) can access the variables in one shell script from another. But this is not working in my scripts. Can somebody please help. Thanks in advance.

Hi I am a newbie on nginx, I tried to set it up on my server(running Ubuntu 4),  which already has apache running.


So after I `apt-get install` it, I tried to start nginx. Then I get the message like this:

    Starting nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
    configuration file /etc/nginx/nginx.conf test is successful
    [emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
    [emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
    [emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
    [emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
    [emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)

That makes sense as Apache is using port 80.

Then I tried to modify `nginx.conf`, I reference some articles, so I changed it like so:


       server {
    
            listen       8080;
    
            location / {
             proxy_pass  http://xx.xx.xx.xx:9500;
             proxy_set_header   Host             $host:8080;
             proxy_set_header   X-Real-IP        $remote_addr;
             proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
             proxy_set_header Via    &quot;nginx&quot;;
            }
     

After saving this and try to start nginx again,  I still get the same error as previously.  I cannot really find a related post about this, could any good people shred some light?

How to start nginx via different port(other than 80)

I just installed nginx and php fastcgi about an hour ago, and after reading examples of a quick starting configuration, and the nginx documentation etc, I just cant get it to work.

No matter what I change or try, I always only get the &quot;Welcome to Nginx!&quot; screen on &quot;localhost/...&quot; - I cant even call a simple index.html

My config:

(the stuff in the comments is what I tried out)

    // default nginx stuff (unchanged)
    
    server {
        #listen 80 default_server;
        #listen 80 default;
        listen 80;

        #server_name localhost;
        #server_name _;

        #access_log /var/log/nginx/board.access_log;
        #error_log /var/log/nginx/board.error_log;
        
        #root /var/www/board;
        #root /var/www/board/public/;
        root /var/www/board/public;

        #index index.html;
        index index.html index.htm index.php;
    }

If I understand it right, this should be the easiest setup, right? just define `listen 80;` and  `index index.html;` but I just cant get it to work

The file /var/www/board/public/index.html exists and has content

Before I waste 2 more hours trying out something, can someone of you give it a quick watch and tell me what I&#39;m doing wrong? Thanks.

correct configuration for nginx to localhost?

    server {
        #listen   80; ## listen for ipv4; this line is default and implied
        #listen   [::]:80 default ipv6only=on; ## listen for ipv6

        #root /usr/share/nginx/www;

    root /home/ubuntu/node-login;
        # Make site accessible from 
        server_name ec2-xx-xx-xxx-xxx.us-west-1.compute.amazonaws.com;

    location /{
        proxy_pass http://127.0.0.1:8000/;
        proxy_redirect off;
    }
   }

this results in nignx error [warn] conflicting server name &quot;ec2...&quot; on 0.0.0.0:80 ignored
I dont understand, any explanation appreciated. Thanks.

nginx error &quot;conflicting server name&quot; ignored

I&#39;m looking to serve the root url of a subdomain and directory of a subdomain to two different folders on my server. Here is the simple set-up that I have and is not working...

    server {

        index index.html index.htm;
        server_name test.example.com;

        location / {
                root /web/test.example.com/www;
        }

        location /static {
                root /web/test.example.com/static;
        }
    }


In this example going to `test.example.com/` would bring the index file in `/web/test.example.com/www`

and going to `test.example.com/static` would bring the index file in `/web/test.example.com/static`

I&#39;m building a website with flask where users have accounts and are able to login.
I&#39;m using flask-principal for the loging in part and the role management.
Is there a way of making the user&#39;s session expire after say 5 minutes or 10 minutes?
I was not able to find that in flask documentation or, flask-principal&#39;s documentation.

I thought of a way of doing it by hand, set a variable server-side with a time tag at the moment of login and at the next action the user takes, the server verifies the time-delta on that timestamp and deletes the session. 

Is there an easy way to make sessions timeout in flask?

How to retry a bash command until its status is ok or until a timeout is reached?

My best shot (I&#39;m looking for something simpler):

    NEXT_WAIT_TIME=0
    COMMAND_STATUS=1
    until [ $COMMAND_STATUS -eq 0 || $NEXT_WAIT_TIME -eq 4 ]; do
      command
      COMMAND_STATUS=$?
      sleep $NEXT_WAIT_TIME
      let NEXT_WAIT_TIME=NEXT_WAIT_TIME+1
    done

How to close idle connections in PostgreSQL automatically?

I open a TCP socket and connect it to another socket somewhere else on the network. I can then successfully send and receive data. I have a timer that sends something to the socket every second.

I then rudely interrupt the connection by forcibly losing the connection (pulling out the Ethernet cable in this case). My socket is still reporting that it is successfully writing data out every second. This continues for approximately 1hour and 30 minutes, where a write error is eventually given.

What specifies this time-out where a socket finally accepts the other end has disappeared? Is it the OS (Ubuntu 11.04), is it from the TCP/IP specification, or is it a socket configuration option?

SO has many articles mentioning this error code:

    FastCGI sent in stderr: &quot;Primary script unknown&quot; while reading response header from upstream...

That probably means that this error message is more or less useless.  

The message is telling us that the FastCGI handler doesn&#39;t like whatever it was sent for some reason.  The problem is that sometimes we have no idea what the reason is.

So I&#39;m re-stating the question -- How do we ***debug*** this error code?

Consider the situation where we have a very simple site, with just the phpinfo.php file.  Additionally, there is a very simple nginx config, as follows:

    server {
        server_name testsite.local;
    
    	root /var/local/mysite/;
     
        location / {
            index index.html index.htm index.php;
        }
     
        location ~ \.php$ {
            include /etc/nginx/fastcgi_params;
            fastcgi_pass  fastcgi_backend;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        }
    }

**How can we see output/log exactly what fastcgi_params got sent to the script?**

**How can we see the actual error message?**  In my case, I&#39;m using php-fpm.  It has no info in the log about this error.  The logs do not append any rows for this error.  Is there a verbose mode for php-fpm?

    /var/log/php-fpm/error.log
    /var/log/php-fpm/www-error.log

I&#39;ve tried to set this in the php-fpm.conf file

    log_level = notice

and this in the php-fpm.d/www.conf file:

    catch_workers_output = yes









How to debug &quot;FastCGI sent in stderr: Primary script unknown while reading response header from upstream&quot; and find the actual error message?

I created an internet gateway in AWS VPC dashboard, I attached it to a VPC then I want to detach it but I keep getting this error:

    Network vpc-xxxx has some mapped public adresses, Please unmap those public addresses before detaching the gateway. ( Service: AmazonEC2; Status Code: 400; Error Code: DependencyViolation; Request ID: qfdqsdf)

What to do to detache this IGW ? Why exactly do I get this error?

I need to get rid of this IGW without deleting extra resources. please any ideas?

For information, the route table of the VPC does contain public addresses but they are routed to other targets. This IGW is not set as target anywhere.
