Connection drop during upgrade

Hi, I would really appreciate any help on this.

Short story:

Had the ISPConfig server up an running on the remote location.
Centos 5.2 Perfect Install + ISPConfig 2.2.28
All users, domains everything ready.

Tried to upgrade to 2.2.29 over ssh.
During the compiling, the connection dropped.
I was unable to get back to that session.

Since I did not know of the internal workings of ISPConfig I followed the suggestion to delete the install_ispconfig folder and start the installation again.

This time the installer did not recognize the system as ISPConfig system and tried to start a fresh install.

As I searched the forum, I learned that the installer replaces /root/ispconfig folder. I have no backup of that folder. This folder is now missing.
The mail is working, the ISPConfig admin interface is not.

I have backups of:
/etc
/www

Should I try to undelete install_ispconfig folder that I removed?
Could I try to make a backup of mysql ispconfig_db database and reinstall (new install)?
Would that preserve users created?

Thanks for all the help!

Only now I have learned that I should use screen for the upgrade..

First:
make backup of your ispconfig database
and /home/admispconfig + /root/ispconfig direcotries..
if anything goes wrong you can put the directories and database back and everything runs as before

against drop - use "screen" command which allows you connect back to your session when connection si dropped

 

Ok, the following folders are in place and intact and I also have backups:

/etc
/home/admispconfig
/home/ispconfigend
/var/lib/mysql
/var/www
+ mysqldump of db_ispconfig

The only folder missing from the failed upgrade is:

/root/ispconfig

This obviously caused the installer script to think that there is no previous ISPConfig installation on the system. So when I tried to upgrade, the installer wanted to do fresh install.

So, Till, if I make an empty directory /root/ispconfig and then rerun the installation, the installer will find existing ISPConfig installation with all the users, domains, etc.?

Thanks,

Peter

 

Yes, that's right.

 

BTW, to prevent this from happening again, you can use screen: http://www.howtoforge.com/linux_screen

 

Thanks, I did what you advised (using screen) and the installer indeed found an existing ISPConfig installation.

I have however, at least one more problem.
ISPConfig panel does not start.

The browser says:

Code:

SSL received a record that exceeded the maximum permissible length.
(Error code: ssl_error_rx_record_too_long)

The console output:

Code:

/etc/init.d/ispconfig_server start
Starting ISPConfig system...
/root/ispconfig/httpd/bin/apachectl startssl: httpd could not be started
ISPConfig system is now up and running!

Error log:

Code:

cat /root/ispconfig/httpd/logs/error_log
[Mon Dec 22 10:37:04 2008] [error] mod_ssl: Init: Unable to read server certificate from file /root/ispconfig/httpd/conf/ssl.crt/server.crt (OpenSSL library error follows)
[Mon Dec 22 10:37:04 2008] [error] OpenSSL: error:0D06B08E:asn1 encoding routines:ASN1_D2I_READ_BIO:not enough data

Should I try to recreate certificates like this?

If yes, I noticed that there is a password to be entered:

Do I have to set a new password here?
I do not remember having to enter any passwords for serverkey when doing fresh installation. Why now?
Is this the same option as in the ISPConfig Installation Manual, step 7 and 8?
I want to be able to restart the machine remotely.

 

Yes.

You can make up a password here.

You will be able to reboot the machine remotely.

 

Hello again!
Big thanks to everyone, especially falko, for helping me with this.

Your advice helped perfectly.
Since it was not so urgent, I waited a while, and only resolved this issue last week.
It just worked.

With best regards,

Peter

Keep it up!!!
