Wildlfy with Nginx not working properly - nginx

Question

We had installed wildfly for a couple of time working correctly. We configured right now Nginx as reverse proxy for wildfly.
We're getting on OPTIONS method 405 Method Not Allowed. Here is the configuration of nginx.
/etc/nginx/conf.d/wildfly.conf
upstream wildfly {
server 127.0.0.1:8081;
}
server {
listen 8080;
server_name guest1;
location/ {
proxy_pass http://wildfly;
}
}
Error obtained after installing nginx:
This is the error got by nginx:
2017/06/23 08:16:54 [crit] 1386#0: *9 connect() to 127.0.0.1:8081 failed (13: Permission denied) while connecting to upstream, client: 172.28.128.1, server: guest1, request: "OPTIONS /commty/cmng/users HTTP/1.1", upstream: "http://127.0.0.1:8081/commty/cmng/users", host: "guest1:8080"
What I'm missing?

Answer 1

I've done the following to finally make it work on CentOS7 + Wildfly.
Vagrant up
Install NGINX
yum install epel-release
yum install nginx
Configure /etc/nginx/nginx.conf (default configuration)
Configure /etc/nginx/conf.d/wildfly.conf (using port 80 for nginx and 8080 for wildfly)
upstream wildfly {
server 127.0.0.1:8080;
}
server {
listen 80;
server_name guest1;
location / {
proxy_pass http://wildfly;
}
}
Also set SELinux permissive for let nginx work.
$ setenforce permissive
After that wildfly is working properly through nginx.
