Well, I followed:
and looking at the printed sheets, where I checked every step off, I don't see what I may have missed. The mysql install in that howto only has about 4 steps, with the install loading mysql-server mysql-client and libmysqlclient15-dev.
The /etc/init.d/mysql restart worked, returning [OK]
After following that howto, the ISPConfig compile DID fail with some message about the php not compatible. Sorry, I did not save the apt-get command I found in Google, I would have posted it...Is there a log that may still have the command? I'll look for it....
PS I found one item I added, this is the apt-get command from another post: (it actually came from this forum site!)
When I re-compiled, ISPConfig compile worked ok.
