How to cat via ssh and sed at the same time.?

I am trying to write a script to automatically create conf files and remote servers. I would like to do all this without creating files locally and copying them .

Here is what I have tried.

Code:

sitename=$1
prodserver=$2
ssh $prodserver "cat > /data/$sitename.conf" << cat |sed "s/changeme/$sitename/g" << EOF
<VirtualHost *:80>

        ServerName dev.changeme

        DocumentRoot /var/www/html/www.changeme/

        <Directory /var/www/html/www.changeme/>
                Options FollowSymLinks MultiViews
                AllowOverride All
                Order allow,deny
                Allow from all
        </Directory>
        ErrorLog /var/log/httpd/dev.changeme-error.log
        LogLevel warn

        CustomLog /var/log/httpd/dev.changeme-access.log combined


</VirtualHost>

EOF

I know it's way wrong I have tried many iterations. Just hoping can set me on a better track if they understand what I am trying to do.

and yet the file is written

Many thanks!

Have you tried:

Code:

sitename=$1
prodserver=$2
sed "s/changeme/$sitename/g" << EOF | ssh $prodserver "cat > /data/$sitename.conf"
<VirtualHost *:80>

        ServerName dev.changeme

        DocumentRoot /var/www/html/www.changeme/

        <Directory /var/www/html/www.changeme/>
                Options FollowSymLinks MultiViews
                AllowOverride All
                Order allow,deny
                Allow from all
        </Directory>
        ErrorLog /var/log/httpd/dev.changeme-error.log
        LogLevel warn

        CustomLog /var/log/httpd/dev.changeme-access.log combined


</VirtualHost>
EOF

Oops. I left behind an unneeded cat. The code has been fixed above.

In addition you could leave out the sed and use:

Code:

cat << EOF | ...
<VirtualHost *:80>

        ServerName dev.${sitename}

        DocumentRoot /var/www/html/www.${sitename}/

        <Directory /var/www/html/www.${sitename}/>
                Options FollowSymLinks MultiViews
                AllowOverride All
                Order allow,deny
                Allow from all
        </Directory>
        ErrorLog /var/log/httpd/dev.${sitename}-error.log
        LogLevel warn

        CustomLog /var/log/httpd/dev.${sitename}-access.log combined


</VirtualHost>
EOF

I accidentally left in an unneeded and unwanted cat. I have updated my suggestion in message #2 in this thread to fix the problem. But, Scrutinzer's suggestion is better; you don't need sed of this application.
