Im trying to use an if statement that allows me to ignore headers only when caching a request. This is the code I implemented ( on /etc/nginx/sites-available/example.com) :
if ($skip_cache = 0) {
fastcgi_ignore_headers X-Accel-Expires Expires Cache-Control;
}
When I run a check on the configuration file's syntax, i get the following error:
nginx: [emerg] "fastcgi_ignore_headers" directive is not allowed here in /etc/nginx/sites-enabled/chartership.com:46
nginx: configuration file /etc/nginx/nginx.conf test failed
Do you guys have any suggestions to steer the implementation correctly?

For customizing of ModSecurity configuration I have included to the modsecurity.conf following line:
Include /etc/modsecurity/*.conf
But without any conf file in the directory (usual case on my enviroment), a kong failing during startup
Error: could not prepare Kong prefix at /usr/local/kong: nginx
configuration is invalid (exit code 1): nginx: [emerg]
"modsecurity_rules_file" directive Rules error. File:

How I can solve the case with optional include?

I want to deploy a little Flask webapp on a root cloud server with Plesk installed. I followed this tutorial as it uses Nginx and Gunicorn, like proposed by the developer of Flask: Miguel Grinberg.
The problem is that Plesk has a modified variant of nginx pre-installed named sw-nginx and I've absolutely no clue on how to implement that line of code:
server {
listen 80;
server_name my.subdomain.com;
location / {
include proxy_params;
proxy_pass http://unix:/var/www/vhosts/mydomain.com/my.subdomain.com/myproject/app.sock;
}
}
If I just put in in a .conf file, the configtest of Nginx fails:
$ nginx -t
nginx: [emerg] open() "/etc/nginx/proxy_params" failed (2: No such file or directory) in /etc/nginx/conf.d/myproject.conf:6
nginx: configuration file /etc/nginx/nginx.conf test failed
Maybe the syntax of the proxy_pass value is wrong (I tried many, here I put one of them), or maybe the proxy_pass param isn't supported or has to be implemented somewhere else?
PS: I also found this answer How to deploy Flask project on Plesk subdomain
But I read somewhere, that replacing sw-nginx by the standard nginx wouldn't be supported by Plesk. Don't want to break anything...
Thanks for your help.
I am trying to implement "ssl_preread" in my nginx. My nginx is compiled with "--with-stream_ssl_preread_module" this module.
I mentioned "ssl_preread on;" in server directive of nginx.conf. But i am getting below error.
nginx: [emerg] "ssl_preread" directive is not allowed here in /opt/nginx/conf/nginx.conf:43
I am following below doc.
http://nginx.org/en/docs/stream/ngx_stream_ssl_preread_module.html
Compile with both modules
--with-stream
--with-stream_ssl_preread_module
Create a stream block outside http block
stream {
upstream app {
server IP1:Port;
server IP2:Port;
}
map $ssl_preread_server_name $upstream {
default app;
}
server {
listen PORT;
ssl_preread on;
proxy_pass $upstream;
}
}
This worked for me. Let me know if this works for you too
Maybe U need to update Nginx to lastest version. 1.10 I meet this error too, but 1.18 the config is OK.
Perhaps this is a late answer. I had the following issue when installing nginx 1.14 from CentOS 8.3 repo.
The error was: MisconfigurationError('Error while running nginx -c /etc/nginx/nginx.conf -t.\n\nnginx: [emerg] unknown "ssl_preread_server_name" variable\nnginx: configuration file /etc/nginx/nginx.conf test failed\n',)
The nginx plugin is not working; there may be problems with your existing configuration.
The error was: MisconfigurationError('Error while running nginx -c /etc/nginx/nginx.conf -t.\n\nnginx: [emerg] unknown "ssl_preread_server_name" variable\nnginx: configuration file /etc/nginx/
nginx.conf test failed\n',)
I fixed it by upgrading the very latest nginx-1:1.20.0-1.el8.ngx.x86_64, following this URL
http://nginx.org/en/linux_packages.html#RHEL-CentOS
My server setup works for a Rails 4.0 app, but fails on a 4.2 app. I get this error:
An error occurred.

If I manually put in an index.html file in the public directory, I can see that. But it fails when I want to go to the root path of the app. Any ideas?
OK so this is a bit embarrassing. To further troubleshoot my application, I started in production mode on my local machine, and when I loaded the app I got the following error on the web page:
Missing `secret_key_base` for 'production' environment, set this value in `config/secrets.yml`
So that was it. I guess I missed this new security feature by jumping straight from Rails 4.0 to 4.2 Not sure why it didn't show in the logs, but at least I found it eventually.
I am very new to nginx and lua .i have installed Openresty .
below is my code in nginx.conf file .
server{
location /hellolua {
default_type 'text/plain';
content_by_lua ' local name = ngx.var.arg_name or "Anonymous"
ngx.say("Hello, ", name, "!") ';
}
}
When i am running sudo service nginx start i am getting error Starting nginx: nginx: [emerg] unknown directive "content_by_lua" in /etc/nginx/nginx.conf:24
nginx: configuration file /etc/nginx/nginx.conf test failedt
Please let me know what i am missing .
It seems to me, as if you haven't installed the right module? ngx_lua (http://wiki.nginx.org/HttpLuaModule)
You mention OpenResty. Did you configure it with lua? If not, the guide is here(http://wiki.nginx.org/HttpLuaModule#Installation).
Quick resumé:
The ngx_openresty bundle can be used to install Nginx, ngx_lua, either one of the standard Lua 5.1 interpreter or LuaJIT 2.0, as well as a package of powerful companion Nginx modules. The basic installation step is a simple ./configure --with-luajit && make && make install.
You can manually compile ngx_lua into nginx too, the full guide is in the link too.
After comment-discussing - I removed the irrelevant part of the answer.
By default, OpenResty's nginx is installed into the path /usr/local/openresty/nginx/sbin/nginx. Your system's default nginx init configurations need an update to point to the right locations.
