What would be the best way to script create an Apache vhost file.

So I finally setup Observium on CentOS & this evening.

At one point, the instructions state that you need to setup the vhost settings for Apache.

Well this is easy enough, but I want something that I can copy/paste or even eventually put into a one liner with semicolons.

I know I can use sed to replace pieces in an existing text file.

#replace the default username and password as just setup
sed -i 's/USERNAME/someuser/' /opt/observium/config.php
sed -i 's/PASSWORD/somepassword/' /opt/observium/config.php

I know I can use touch to create a new file.

#create vhost file for website
sudo touch /etc/httpd/conf.d/observium.conf

Now I need to get this information into observium.conf

<VirtualHost *:80>
	DocumentRoot /opt/observium/html/
	ServerName  observium.domain.com
	CustomLog /opt/observium/logs/access_log combined
	ErrorLog /opt/observium/logs/error_log
	<Directory "/opt/observium/html/">
		AllowOverride All
		Options FollowSymLinks MultiViews
		Require all granted
	</Directory>
</VirtualHost>

What would be the best way to handle that? Obviously I can open vi or nano and paste it in, but I don't want to do that.

If you have a block of pre-existing text ready to go in a script that you want to get into a file you generally do it using an cat command.

Like this...

cat > observium.conf <<'_EOF'
<VirtualHost *:80>
    DocumentRoot /opt/observium/html/
    ServerName  observium.domain.com
    CustomLog /opt/observium/logs/access_log combined
    ErrorLog /opt/observium/logs/error_log
    <Directory "/opt/observium/html/">
        AllowOverride All
        Options FollowSymLinks MultiViews
        Require all granted
    </Directory>
</VirtualHost>
_EOF
