Nginx normal user startup configuration error: && springboot-swagger & Unable to infer base url

2022/01/04 08:50:55 [crit] 8715#8715: *107201 mkdir() “/var/cache/nginx/proxy_temp/3” failed (13: Permission denied) while reading upstream, client:, server: localhost, request: “GET /prod-api/swagger-ui/swagger-ui-standalone-preset.js?v=3.0.0 HTTP/1.1”, upstream: “http://[::1]:8090/swagger-ui/swagger-ui-standalone-preset.js?v=3.0.0”, host: “hostname:9000”, referrer: “http://hostname:9000/prod-api/swagger-ui/index.html”. 


Looking at the nginx log, there is no /var/cache/nginx/proxy/temp permission. Authorize it.
sudo chmod a+w /var/cache/nginx/proxy_temp -R

How to Install nginx yum:

Add repo of nginx:

echo '[nginx]
name=nginx repo
enabled=1' > /etc/yum.repos.d/nginx.repo


yum update
yum install nginx

Did you install the latest version of nginx directly?
log]$ whereis nginx
nginx: /usr/sbin/nginx /usr/lib64/nginx /etc/nginx /usr/share/nginx /usr/share/man/man8/nginx.8.gz

Then you need to configure the normal user path of nginx. Create the relevant directory and copy the configuration file. Authorize proxy_temp. As above.
log]$ mkdir -p /data/nginx/log /data/nginx/run  /data/nginx/conf.d
log]$ cp /etc/nginx/nginx.conf /data/nginx/
log]$ cp /etc/nginx/conf.d/default.conf /data/nginx/conf.d/
sudo chmod a+w /var/cache/nginx/proxy_temp -R
log]$ vi /data/nginx/nginx.conf

#user  nobody;
worker_processes  auto;

error_log  /data/nginx/log/error.log notice;
pid        /data/nginx/run/;

events {
    use epoll;
    worker_connections  1024;

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /data/nginx/log/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /data/nginx/conf.d/*.conf;

Hope this article will help you.
