What is the purpose of running PHP-FPM in its own container instead in the same container as apache2/nginx?

I’m fairly new to Docker so excuse any obvious ignorance or misunderstandings. That said, I’ve been coding and configuring web applications for a long time now. I have recently been dabbling with some more sophisticated (Docker and “traditional”) web/application server setups and experimenting with performance enhancements and simplifying deployments.

My personal favorite configuration to use for most projects thus far is nginx as a (mostly) “static file” web server &&|| caching mechanism &&|| Load Balancer in a reverse proxy config with Apache v2.4+ as the “backend” which runs PHP (also Perl &&|| Python) in a “FastCGI” (PHP-FPM) configuration (with mod_php disabled) and mpm_events (instead of mpm_prefork). We can always add in something else also such as REDIS or memcached, where applicable (but I rarely see a significant performance gain when using Cloudflare caching).

I’ve been dabbling with a few different ways to keep my “favorite web server composition” flexible and “ephemeral” enough to accommodate any and all possible options for further performance gain or resource load management. What I keep seeing is that there seems to have been a shift towards using PHP-FPM in its own separate “stand-alone” Docker container sometimes around late 2019.


While I can appreciate keeping resources isolated and separate for an easier to debug/config/secure configuration(s), I don’t fully understand what the benefits are to having PHP-FPM in a separate Docker container that is implicitly REQUIRED by the application that the Docker containers are comprising.

If anything, having a separate PHP-FPM container seems like additional configuration, additional resource consumption and an even more complicated build/deploy consideration in a CI/CD pipeline.

I can even get onboard with “simple preference”, such as instead of using Apache2 and nginx on the same Ubuntu/Debian or RHEL/CentOS container, break off nginx into its own container(s) and simply config your hostname(s) &&|| IPs and ports appropriately.

But what is a practical use case and advantages for having PHP-FPM separated from Apache or nginx containers for any additional benefit beyond perhaps using more Dockerfile &&|| docker-compose.yaml and less ba.sh scripting to get the same job done? If any part of the application fails or falters, then functionality will suffer. The additional network &&|| docker-network communications and hostname resolutions seems like it would just be a performance penalty over combining certain aspects of the docker-composer-ed application together, rather than splitting them up simply for the sake of splitting them up.

Openresty cookies whitelist when using proxy_pass

I’m setting up an openresty reverse proxy that will dispatch traffic to one of 2 backends depending on the path.

I would like certain cookies from backend1 not to be passed to backend2.

How should I do ?

Here is an my nginx.conf :

worker_processes 1;
error_log stderr;


events {
    worker_connections 1024;
http {
    resolver local=on;

    server {
        listen 80;

        root   /usr/share/nginx/html;
        include       /usr/local/openresty/nginx/conf/mime.types;
        set_by_lua $backend_url 'return os.getenv("BACKEND_URL")';
        set_by_lua $backend2_url 'return os.getenv("BACKEND2_URL")';

        location / {
            try_files $uri $uri/ /index.html;

        location ~ /backend/(.*)$ {
            proxy_pass $backend_url$1$is_args$args;

        location /backend2/ {
            access_by_lua_block {
            proxy_pass $backend2_url;

Не загружается проект на Django с VPS Ubuntu, после настроек gunicorn, supervisor и nginx

Всем привет! Столкнулся с проблемой, произвел все настройки на сервере, проверил работу gunicorn, запустил проект напрямую командой gunicorn Superman.wsgi:application --bind, сайт запустился, но без static файлов. Далее установил supervisor, так же произвел отдельную настройку под него и настроил nginx, при проверке supervisor sudo supervisorctl status Superman сервер ответил, что он работает, при проверке nginx sudo nginx -t сервер так же отвечает положительно successful, но когда я забиваю IP своего сайта в строку поиска браузера сайт не прогружается, ошибка – Сайт не позволяет установить соединение, nginx пусто. В чем может быть проблема, возможно я не правильно настраиваю proxy_pass? Настройки прилагаю ниже, ПРОШУ ПОМОЧЬ В РЕШЕНИИ ПРОБЛЕМЫ, сутки ищу решение и ничего((

Forward SSH from Reverse Proxy Server through VPN to Home Server

I’m trying to set up GitLab on my home server. HTTPS is working and I can get to GitLab’s interface, but SSH is not and thus I can’t push code to the server.

Here is the setup:

Cloudflare <--> Reverse Proxy (nginx, hosted on Digital Ocean) <--- VPN ---> Untangle Firewall <--> GitLab Server (on ESXi)

If I try to SSH directly from the Reverse Proxy to the GitLab server (over VPN connection), it works perfect.

If I try to SSH from my laptop using the domain name, I get:

kex_exchange_identification: Connection closed by remote host
Connection closed by port 2095

If I try to SSH from my laptop using the Reverse Proxy’s IP (thus cutting out Cloudflare), I get:

Bad packet length 1231976033.
ssh_dispatch_run_fatal: Connection to {{ IP }} port 2095: message authentication code incorrect

I’m currently trying to use the nginx stream module to do so, and this is the stream setup:

stream {
        upstream git-ssh {
                server {{INTERNAL GITLAB IP}}:22;
        server {
                listen 2095;
                proxy_pass {{INTERNAL GITLAB IP}}:22;
                proxy_protocol on;

The reason I have upstream git-ssh and then don’t use it was because I was wondering if that was the problem, but it makes no difference if I use it or not.

I’m not familiar with iptables, but I tried the following commands:

sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 2095 -j DNAT --to-destination {{GITLAB IP}}:22
sudo iptables -t nat -A POSTROUTING -o eth0 -p tcp --dport 2095 -j SNAT --to-source {{PROXY IP}}

But it didn’t seem to work. ssh just sits there returning nothing and eventually times out.

I am lost now, and was hoping someone could give me pointers?

How can use multi location and regex in nginx?

Please help me with nginx.conf that is regex and multi location.

When I create the nginx.conf with next location, proxy_pass works correctly:

location = /test-a-1-1 {
       proxy_pass http://test-a-1-1;
       proxy_set_header Host $host;
       proxy_set_header X-Real-IP $real_remote_addr;
       proxy_redirect off;

  location = /test-b-1-2 {
      proxy_pass http://test-b-1-2;
      proxy_set_header Host $host;
      proxy_set_header X-Real-IP $real_remote_addr;
      proxy_redirect off;

But I have many locations and I want use multi location, but in this configuration i get the error –

test-b-1-2 could not be resolved (3: Host not found)

location ~ ^/(test-a-[0-9]-[0-9]|test-b-[0-9]-[0-9]) {
                set $test $1;
                proxy_pass http://$test;
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_redirect off;

Please help me with regex and multi locations.
Thank you.

nginx 1.14 proxy to serve stale content when upstream is not available

I have nginx running inside a Docker container on Docker for Windows with WSL2. It’s function is as a caching proxy to an upstream IIS server.

container/userspace: CentOS 8 container running SystemD as pid1.
nginx version: 1.14 as provided by CentOS 8.
The config file dates back from nginx 1.1 days on RHEL6, but reports no syntax errors.

Problem: When upstream is down, instead of service stale content, Nginx reports “Gateway Timeout.”
Expectation: Nginx would still serve static assets from cache.

The proxying appears to work as I can see requests Hit and Miss, respectively in the access.log.

Could anyone with more nginx experience comment on this use case and if there’s anything obviously missing in the configuration?

NGINX serving by IP only, not by server name

A Raspbery Pi running (arm-)Arch sits behind my router NAT. The RasPi has a static IP and an nginx serving on port 8093. (The nginx is listening on port 80 for another webpage.)

Nginx with Varnish : all listen directive pointing to 808* ports but nginx still listen to 80

I’m running instances of Symfony or Drupal websites on two Debian servers, with Nginx listening to 443, Varnish listening to 80 and passing to nginx on listening custom ports 80** for each vhost.

Recently I added a new website to one of the servers. Then I began to run in this well documented error nginx: [emerg] bind() to [::]:80 failed (98: Address already in use).

Despite there is no nginx server block at all listening to :80 port, neither any server block without listen directive, Nginx began to listen on port 80 all together with the custom ports.

I also already read all the docs and posts about handling dual-stack IPv4 and IPv6 correct new syntax, and tried all possible syntaxes such as below, no way.

Working directive before crash : listen x.x.x.x:8082;
Tried adding listen [::]:8082 ipv6only=on;. No change.

I listed, and killed process many times with sudo fuser -k 80/tcp before restarting systemctl varnish, nginx, even daemon-reload…

Last, I checked my history but can’t find what could have caused this sudden behavior. The lone point I’m not sure about is I changed a couple of sysctl.conf params, but hopefully reverted them, just in case, I’m not used to this part od administration : cat /etc/sysctl.conf | grep net.ipv4.conf

#net.ipv4.conf.all.accept_redirects = 0
# net.ipv4.conf.all.secure_redirects = 1
#net.ipv4.conf.all.send_redirects = 0
#net.ipv4.conf.all.accept_source_route = 0
#net.ipv4.conf.all.log_martians = 1

Here’s my configuration.

cat /etc/nginx/nginx.conf (relevant 2 lines, no html / server block in it)

I’m wondering what could have caused a config I’m working with since years to bug ?

I carefully studied these Q&A and a bunch of doc or posts, with no success : Nginx tries to run on port 80 but the configs have been removed ; Nginx will not start (Address already in use) ; nginx – bind() to failed (98: Address already in use)

Make host header correct from upstream

I configured simple load balancer scheme on the windows:

upstream app.local {
    server app1.local:8001 fail_timeout=10s max_fails=10;
    server app2.local:8002 fail_timeout=10s max_fails=10;

server {
    listen 8000;

    location / {
        proxy_pass http://app.local;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $remote_addr;

Changed hosts file like this       app.local       app1.local       app2.local

All fine, but my web servers behind app1.local and app2.local receive incorrect headers Host: app.local and therefore don’t want resolve requests. I readed
the post where the same problem but top answer not resolved my and i don’t want to use the double layer proxy option straight off.

WordPress website hosted on nginx ubuntu isn’t loading anymore

WordPress website hosted on nginx ubuntu isn’t loading anymore

I just found out the WordPress website isn’t running anymore. When opening example.in, it simply shows the text Error establishing a database connection. The wp website is the folder /var/www/examplewp

I have other non-PHP based websites running smoothly on the same server. Even the xxx.example.in which is a non-php based website is working.

I tried opening files such as example.in/readmore.html or example.in/hello.txt which I created in the base folder of the WP and that’s working.

Here’s the details:

php -v

I tried restarting the server with sudo service nginx restart but it doesn’t help. Even the HTML or TXT files aren’t opening. I tried with the command line sudo service php7-fpm restart but got the response:

Failed to restart php7-fpm.service: Unit php7-fpm.service not found.

I can open info.php file though which has the phpinfo(); and see all the PHP related files.

I also check the error log but it’s empty: /var/log/nginx/wp_client_error.log

I tried restarting the mysql with this command land: sudo /etc/init.d/mysql start and got the following error:

[....] Starting mysql (via systemctl): mysql.serviceJob for mysql.service failed because the control process exited with error code.
See "systemctl status mysql.service" and "journalctl -xe" for details.
