Generate NGINX virtual hosts script

I created simple script for creating NGINX virtual hosts so that you don’t have to do it manualy for every new website. Script was created for Linux – CentOS 7 – operating system but it should work on other distributions too. It is written in bash. You will also need wget and tar installed for script to work – wordpress install option.

What it does is pretty straightforward. On input side it will ask you for domain name, SSL option and WordPress installation. You can choose between http and https virtual host definition. By default it will create document root for your domain and NGINX configuration file for that domain. If you choose option for WordPress installation, then it will also download latest wordpress version and unpack files to your newly created document root. You’ll still need to create database manually and finish WordPress installation. This script is suitable for basic NGINX website configurations

Just download script here and template files. Put script createsite to your /usr/sbin/ directory and make it executable. Of corse you can change virtual host templates according to your needs too.

Directadmin – enable and configure Spamassassin automatically when adding user

By default, when you add new user in Directadmin, Spamassassin is disabled. Some users may not know about Spamassassin, so they’ll have it disabled and will receiving a lot of spam. So it may be good practice to enable Spamassassin by default. You can do that by adding below code in your /usr/local/directadmin/scripts/custom/user_create_post.sh script. The first step is well described on Directadmin sites. But you may also want to define some parameters for Spamassassin “on the fly”. You can do that by manipulating filter.conf file.
In this example I want that on user creation:

  1. spam goes to appropriate users spam folder,
  2. I don’t want to delete high scoring spam,
  3. I want to rewrite subject of spam email with *****SPAM*****.

Just add below code in your user_create_post.sh script. And remove script comments (##).

## We enable Spamassassin, create needed files and give them appropriate permissions
if [ “$spam” = “ON” ]; then
DIR=/home/$username/.spamassassin
mkdir $DIR
touch $DIR/user_prefs
chown ${username}:mail $DIR
chmod 771 $DIR
chown $username:$username $DIR/user_prefs
chmod 755 $DIR/user_prefs
touch $DIR/spam
chown mail:$username $DIR/spam
chmod 660 $DIR/spam

## Here we define some variables for Spamassassin by adding some lines to filter.conf
echo “high_score=15” >> /etc/virtual/$domain/filter.conf
echo “high_score_block=no” >> /etc/virtual/$domain/filter.conf
echo “where=userspamfolder” >> /etc/virtual/$domain/filter.conf
echo “rewrite_header subject *****SPAM*****” >> /home/$username/.spamassassin/user_prefs

## Adding operation in task queue
echo “action=rewrite&value=filter&user=$username” >> /usr/local/directadmin/data/task.queue
fi
exit 0;
