check if your proxy is working

Most of the times you may not even need a proxy for apache2. However mysql inside WSL is extremely tricky for some reason. I have ALWAYS had issues until I changed the default port. Hence try this in your file:

sudo nano /etc/mysql/my.cnf
!includedir /etc/mysql/conf.d/
!includedir /etc/mysql/mysql.conf.d/

bind-address =
pid-file     = /var/run/mysqld/
socket       = /var/run/mysqld/mysqld.sock
port         = 3334

Now you should be able to connect to this mysql instance from some gui app on windows too like dbeaver with localhost on port 3334.

If you are victim of unpredictive WSL behavior, do leave a comment

How to fix CORS error for amazon s3 files and resources?

Go to bucket

In the bucket permissions tab

There is a section for CORS, put the following in it and save.

        "AllowedOrigins": [

        "MaxAgeSeconds": 3000,

centos web panel – vhost templates for proxying websocket traffic

Templates location: /usr/local/cwpsrv/htdocs/resources/conf/web_servers/
– Folder main contains main configuration for WebServers
– Folder vhosts contains vhosts configuration for domains (this is what you need)

How to create a template file
The easiest way to do that is to simply copy an existing file and then edit a new file you have created.
Note that you need to have .tpl and .stpl files (tpl is for http and stpl is for https version)

Let’s do one example for apache vhost with nginx

cd /usr/local/cwpsrv/htdocs/resources/conf/web_servers/vhosts/nginx/
cp default.tpl my-template.tpl
cp default.stpl my-template.stpl

Now you can edit these newly created template files.

Template folders explained
List from folder: /usr/local/cwpsrv/htdocs/resources/conf/web_servers/vhosts/

httpd = apache templates
nginx = nginx templates
varnish = varnish templates
php-fpm = php-fpm service templates (used for all php-fpm versions)

add a block

map $http_upgrade $connection_upgrade {
	default upgrade;
	'' close;

also add these inside “location /” block

		proxy_http_version 1.1;
		proxy_set_header Upgrade $http_upgrade;
		proxy_set_header Connection $connection_upgrade;
		proxy_set_header Host $host;

basic cwp with jenkins and nodejs

yum -y install wget
yum -y update

cd /usr/local/src
sh cwp-el7-latest -r no --phpfpm 7.3 --softaculous no


sudo wget -O /etc/yum.repos.d/jenkins.repo \
sudo rpm --import
sudo yum upgrade
sudo yum install epel-release java-11-openjdk-devel
sudo yum install jenkins
sudo systemctl daemon-reload
curl -sL | bash -
sudo yum install nodejs npm -y
sudo npm install [email protected] -g

S3 notes – how to make all s3 images public

aws configure --profile myproject
// to test if it works or not

aws s3 ls --profile myproject

aws s3 cp \
      --exclude "*" \
      --include "*.jpeg" \
      --content-type="image/jpeg"  \
      --metadata-directive="REPLACE" \
      --recursive \
	  --acl public-read \
       s3://myproject/ \
       s3://myproject/ \
	   --dryrun --profile myproject
aws s3 cp \
      --exclude "*" \
      --include "*.jpg" \
      --content-type="image/jpeg"  \
      --metadata-directive="REPLACE" \
      --recursive \
	  --acl public-read \
       s3://myproject/ \
       s3://myproject/ \
	   --dryrun --profile myproject
aws s3 cp \
      --exclude "*" \
      --include "*.jpeg" \
      --content-type="image/jpeg"  \
      --metadata-directive="REPLACE" \
      --recursive \
	  --acl public-read \
       s3://myproject/ \
       s3://myproject/ \
	   --dryrun --profile myproject
// not needed 
aws s3 sync . s3://my-bucket/path --acl public-read

Dont forget to remove dryrun flag once you are sure.
