Company purchased a new server device,
currently we need to migrate the old project to the new one,
while we adding virtual host into new apache,
one of the site cannot access, this just happen today.
the following site cannot access,
coltd.domain.mo
I am trying find out why and fix it.
Following status which checked earlier.
The 000-default.conf file:
<VirtualHost *:80>
# The ServerName directive sets the request scheme, hostname and port t>
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.
#ServerName www.example.com
ServerAdmin webmaster#localhost
DocumentRoot /var/www
# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the loglevel for particular
# modules, e.g.
#LogLevel info ssl:warn

Jan 27 13:11:50 webserver-27 systemd[1]: Starting The Apache HTTP Server...
Jan 27 13:11:51 webserver-27 systemd[1]: Started The Apache HTTP Server.
The *.domain.mo/coltd/ can be access, but not coltd.domain.mo,
Tried create new coltd.domain.mo.conf and test a2dissite 000-default.conf is working,
(assume nothing wrong with apache2)
Checked sudo apache2ctl configtest result syntax OK,
restarted sudo systemctl reload apache2 and restart apache2,
Hopefully found the reason,
we know should be separate all subdomain files, but we plan to do that on next step.
sadly currently small project still adding in 000-default.conf.
Thanks all kinds help.
Before all, yes I have checked other posts like this, this or even this among others.
This being said, let me expose my case:
It works on the dev-env (localhost) completely fine (of course, it doesn't require any proxy)
I also use this curl command to confirm:
curl 'http://localhost:9021/ws' \
--http1.1 \
-H 'Pragma: no-cache' \
-H 'Sec-WebSocket-Key: W/ZEACBv+gi6xA1JeMaO/A==' \
-H 'Upgrade: websocket' \
-H 'Cache-Control: no-cache' \
-H 'Connection: Upgrade' \
-H 'Sec-WebSocket-Version: 13'
and it connects ok.
When I run it on the remote dev server, I have this Apache config:
<IfModule mod_ssl.c>
<VirtualHost *:443>
ServerName dev.remote.com
LogLevel warn
ErrorLog "| /usr/bin/rotatelogs -l /home/user/log/dev.remote.com/error.%Y-%m-%d 86400"

So 2 points here:
1.
I'm sure the WebSocket server is working on the remote server by testing via ssh with the previous curl command. And it connects.
2.
When I try opening the connection from the browser
ws = new WebSocket('wss://dev.remote.com/ws');
the mod_rewrite rule seems ok because the trace is like this:
[Fri May 28 17:37:16.272448 2021] [rewrite:trace2] [pid 15772] mod_rewrite.c(477): [client a.b.c.d:63015] a.b.c.d - - [dev.remote.com/sid#6916462d1a20][rid#69164d3530a0/initial] init rewrite engine with requested uri /ws

So I deduct the rules are working and it's actually making the request via proxy to :ws://localhost:9021/ws
But... there's no connection received in the WebSocket server.
Therefore, I get this on Chrome:
WebSocket connection to 'wss://dev.remote.com/ws' failed
The key was to have proxy_wstunnel mod active >_<
In case it helps anyone...
cd /etc/apache2/mods-enabled
sudo ln -s ../mods-available/proxy_wstunnel.load
stupid error, but I was too focused on the configuration, and it was about enabled mods

in order to access a SpringBoot app I have in the same server, but when I acees the site, this is what I see:
When I start Apache I have this error:

could it be the case you did not enable mod_proxy on your system?
you can do that via "a2enmod proxy_http" on your ubuntu system
I have some issues with setting an clustered environment for weblogic and Apache. The structure is like this: 1 webserver that proxies requests to a clustered environment of 3 weblogic servers.
Everytime i send the request to the apache server , the request gets unhandled. I figured out a part of the problem , but that is something that is not intended in production. whenever i add DynamicServerList On the requests fail. When i switch it to off it works, but that means whenever a server fails , apache will still send requests to that server and user experience would be 0.
EDIT 1: I am using weblogic 12c and apache2.4 for Centos 7
EDIT 2: There is no firewall nor selinux active
Here is my config file for weblogic plugin:
<VirtualHost *:8080>
