I am getting following error whenever I restart my nginx.
nginx: [emerg] cannot load certificate "/etc/ingress-controller/ssl/somefile.pem": PEM_read_bio_X509() failed (SSL: error:0908F066:PEM routines:get_header_and_data:bad end line)\n"
The nginx ingress controller backend is actually reloading and failing during test temp/nginx.conf. This happens a few times until the backend is reloaded successfully and then this error goes away.
Note that somefile.pem contains both cert and key. SSL_Certificate and SSL_Certificate_key in nginx.conf both map to somefile.pem only. Is this the issue?
Also, we see this error only when the kubernetes cluster is heavy.
How do I fix this?
I'm trying to configure my reverse proxy through nginx using this tutorial, but when I go to restart the nginx server, it throws the following error message:
nginx[12681]: nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
I checked out the port using netstat, and I have the following result
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN off (0.00/0/0)
What does this mean? When I go to my domain name, it redirects to the Centos page instead of an nginx page I should be getting. How can I configure the file to get it to redirect to nginx?
Edit:
Added httpd status
httpd.service disabled
mysql.service enabled
my_api.service enabled
nginx.service disabled
I get the above errors when I try to start nginx using systemctl
Running netstat -luntp as root showed that nginx had spawned a master process and a worker. Killing those processes solved the issue
I would like to set up nginx to distribute different servers from request pointing dirrerent domain.
The nginx server environment is below.
CentOS Linux release 7.3.1611 (Core)
nginx 1.11.8
* in configure with --with-stream parameter. build & install from source.
My image is.
server1.testdomain.com ssh request ->(global IP) *nginx server -> (local IP)192.168.1.101 server
server2.testdomain.com ssh request ->(global IP) *nginx server -> (local IP)192.168.1.102 server
nginx server is same glocal IP and same server.
nginx.conf is ...
stream {
error_log /usr/local/nginx/logs/stream.log info;
upstream server1 {
server 192.168.1.101:22;
}
upstream server2 {
server 192.168.1.102:22;
}
server {
listen 22 server1.testdomain.com;
proxy_pass server1;
}
server {
listen 22 server2.testdomain.com;
proxy_pass server2;
}
}
But...
nginx: [emerg] the invalid "server1.testdomain.com" parameter in・・
error occurred. It seems like impossilbe to execute such as listen "22 server1.testdomain.com".
And,
I tried to write "server_name" in "server".
nginx: [emerg] "server_name" directive is not allowed here in・・・
don't permit to use "server_name" in "server".
How do I write config file to distribute difference server for difference domain request?
If you have a idea or information, could you teach me?
Its not possible with nginx because stream module is L3 balancer. SSH protocol works at L5/7.
Its not possible at all because ssh negotiation does not include destination host name.
You can do what you want only using two different IP or using two different ports. In both cases nginx can forward connection, but much better to use iptables in this case.
I am trying to run Nginx, but I am getting the error below:
bind() to 0.0.0.0:80 failed (10013: An attempt was made to access a
socket in a way forbidden by its access permissions)
Please provide some help on what changes I need to do to make it working?
I have tried running on ports other than 80 and it works. but I need it to be running on 80.
Note: I am running on Windows 7 with command prompt running as Administrator.
If the port is already in use, you can change the default port of 80 to a different port that is not in use (maybe 8070). In conf\nginx.conf:
server {
listen 8070;
...
}
After startup, you should be able to hit localhost:8070.
tl;dr
netsh http add iplisten ipaddress=::
Faced similar issue. Run the above command in command prompt.
This should free up port 80, and you'd be able to run nginx.
Description:
netsh http commands are used to query and configure HTTP.sys settings and parameters.
add iplisten :
Adds a new IP address to the IP listen list, excluding the port number.
"::" means any IPv6 address.
For more netsh http commands refer the netsh http commands documentation.
Hope this helps!!
You have to be admin or root to bind port 80. Something you can do if you cannot run as root, is that your application listens to other port, like 8080, and then you redirect messages directed to 80 to 8080. If you are using Linux you redirect messages with iptables.

I got a similar problem, My 80 port was listening to IIS (windows machine). Stopping IIS freed up 80 port.
The problem got resolved...!!
Please check if another Proxy is running under port 80 ---> in my case IIS was running as a reverse proxy, so nginx could not start..
Stopping IIS, and starting of NGXIN solved the problem
My Tomcat server was running on port 80. Changed the port number in conf\nginx.conf file and it started to work.
This is an old question but since I had this problem recently I thought of posting another possible reason in this problem.
If the user is using Docker and has already tried all proposed solutions as stated above and is wondering why port 80 is trying to bind although on your configurations you are overwriting the port to non root port e.g. listen 8080; it seems that the newer NGINX images have a default nginx.conf file in /etc/nginx/conf.d.
Sample:
$ grep -r 80 /etc/nginx/
/etc/nginx/conf.d/default.conf: listen 80;
On my case I removed it on my Dockerfile:
RUN set -x \
&& rm -f /etc/nginx/nginx.conf \
&& rm -f /etc/nginx/conf.d/default.conf
Next step pass from my custom configurations:
COPY ["conf/nginx.conf", "/etc/nginx/nginx.conf"]
I am using the nginx web server bundled with gitlab and I have SSL setup and I am using the non-default port i.e. I have the URL setup as
external_url 'https://www.myserver.com:2443'
However, when I connect with this address, I get a connection was reset error. Running, gitlab-cal tail shows
bind() to 0.0.0.0:80 failed (98: Address already in use)
I am not sure why it still is looking at port 80. Is there some other setting that I must set here.
