Unmodifiable DHCP-Server + Fog / Updating Database failed



  • Hi everyone,
    I want to set up a new fog-Server in our new network environment, but since the dhcp-server is being administered by someone else and so I am not sure, how to configure fog. This is what we got:

    • 10.203.128.1: dhcp (administered by someone else - not modifiable)
    • 10.203.128.2: dns
    • 10.203.128.9: fog + dnsmasq

    I configured dnsmasq according to this: https://wiki.fogproject.org/wiki/index.php?title=ProxyDHCP_with_dnsmasq

    Then I ran the install-script and configured the following:

    • Here are the settings FOG will use:
    • Base Linux: Debian
    • Detected Linux Distribution: Ubuntu
    • Interface: ens160
    • Server IP Address: 10.203.128.9
    • Server Subnet Mask: 255.255.254.0
    • Server Hostname: fog03
    • Installation Type: Normal Server
    • Internationalization: 0
    • Image Storage Location: /images
    • Using FOG DHCP: No
    • DHCP will NOT be setup but you must setup your
      | current DHCP server to use FOG for PXE services.

    Question 1): Are those the correct settings?
    Question 2): Install script says:

    • Changing permissions on apache log files…OK
    • Backing up database…OK
    • Updating Database…Failed!

    Anything I can do here?



  • @Sebastian-Roth , @george1421

    Thanx for your help.
    I set up a new virtual host with ubuntu 18.04.03 LTS server with fog and dnsmasq and everything went fine for the installation part now.
    The ubuntu 18.04.03 provides apparmor by default, so I assume, that apparmor was not the reason for the install-issues I had before.
    Maybe the fact, that I have had mysql installed manually, tried installation of fog and removed mysql after noticing, that fog wants to install mariadb, gave us the troubles we had.

    Now another problem arose, but I opened another thread for that: https://forums.fogproject.org/topic/14197/1-5-7-does-not-capture-correctly

    @Tywyn said in Unmodifiable DHCP-Server + Fog / Updating Database failed:

    Very strange …

    Well, seems like something is really wrong there. I do remember having some strange issue with the DB on Ubuntu myself at some point and through it might be related to the apparmor messages. But as far as I remember this wasn’t actually causing the problem as they were all just warnings. Unfortunately I don’t remember what exactly it was. Maybe you can find something in the DB server logs? Should be in /var/log/mysql or /var/log/mariadb I think.

    I guess I will setup the machine from scratch …

    While you will learn a lot by digging through this things and finding out what is causing it and how to fix it I also side with the idea of just setting it up from scratch.

    So, just to be sure: The steps are:
    Install OS … then
    apt-get -y install git
    cd /root
    git clone https://github.com/FOGProject/fogproject.git
    ./installfog.sh

    Pretty much. Just one command is missing:

    ...
    git clone https://github.com/FOGProject/fogproject
    cd fogproject/bin/
    ./installfog.sh

    @Tywyn So that error is saying that it can’t find the fog database on the server.

    Hopefully you know the root password for the database. You should have been asked that question when you first setup FOG. Originally that password was blank, but later installers prompted the FOG Installer (person) to create a password.

    If your mysql database root user doesn’t have a password key in this.

    mysql -u root
    

    If you are presented with an sql server command prompt then go to the next section.

    If your mysql server requires a root password key in this.

    mysql -u root -p
    

    And then enter root’s password

    Once you are at the mysql command prompt key in : show databases;
    The response should look like this

    MariaDB [(none)]> show databases;
    +--------------------+
    | Database           |
    +--------------------+
    | information_schema |
    | fog                |
    | mysql              |
    | performance_schema |
    | test               |
    +--------------------+
    5 rows in set (0.10 sec)
    

    I’m suspecting that the fog database is missing. Rerunning the installer should recreate that database for you. During the installer it will pause and prompt you to go to the FOG web ui and install the schema. Once the schema is installed return to the fog installer and continue the setup.

    ok, I gave it another try with the system.
    I removed the package apparmor and ran the installer again (no commandline flags)

    Last line was:

  • @Sebastian-Roth
    Removed all mysql-common and mariabd* Packages.
    Reran the installer. It took about 15 minutes to complete this line
    * Installing package: mariadb-server..........................OK

    Then it complained about an existing user “fogproject”. So I removed it and restarted the installer.

    Now I am waiting for about 15 Minutes to complete this:
    * Setting up and starting MySQL...............................

    Does it usually take that long?

    I found in the syslog:

    So, just to be sure: The steps are:

    Install OS … then

    apt-get -y install git
    cd /root
    git clone https://github.com/FOGProject/fogproject.git
    ./installfog.sh
    

    And nothing more, right?

    @Tywyn said in Unmodifiable DHCP-Server + Fog / Updating Database failed:

    I did not install any other applications on the server which use a database. At least I don’t know about any.

    First you should double check there is not something in the DB that you might loose. Run ls -al /var/lib/mysql and post output here.

    If you are absolutely sure there is nothing we could loose in the database I would say you better uninstall all the database packages (apt-get remove mysql* mariadb*), move the old DB files out of the way (mv /var/lib/mysql /var/lib/mysql_old) and re-run the FOG installer without -y switch.



  • @Sebastian-Roth said in Unmodifiable DHCP-Server + Fog / Updating Database failed:

    @Tywyn said:

    See “systemctl status mariadb.service” and “journalctl -xe” for details.
    find: ‘/home//fog_web_1.5.7.BACKUP/management/other/’: No such file or directory

    Should have thought about this earlier. There is something wrong with your database. Did you install MariaDB manually beforehand? Is there any other application running on this server using MariaDB?

    Please run systemctl status mariadb.service and journalctl -xe. Post both outputs here.

    I installed mysql manually beforehand, but since I realized, that fog comes with its own mariadb-installation, I removed the packages mysql-server and mysql-client.
    I see, there is still mysql-common installed, but it seems, that mariadb needs this package, or?

    I did not install any other applications on the server which use a database. At least I don’t know about any.

    Should have thought about this earlier. There is something wrong with your database. Did you install MariaDB manually beforehand? Is there any other application running on this server using MariaDB?

    Please run systemctl status mariadb.service and journalctl -xe. Post both outputs here.

    @Tywyn Yes, FOG does install all the components needed. It’s been like that since the beginning as far as I know. Good you choose to use MariaDB straight away as this is the default now and while moving from MySQL to MariaDB shouldn’t be too much of trouble Ubuntu is doing a really bad job on this. Sorry to say this but other distros do it way better. Never mind.

    Our daily silent install testing (using ./installfog.sh -y as well) reports successful install for Ubuntu 18.04 and FOG 1.5.7 (currently master). So we should probably look at all the logs to see why the step “Updating Database” failed. See my signature on apache and php-fpm logs. As well you have a sub directory in the path where you run the installer script (fogproject/bin/error_logs). Please post the last 20 lines of fog_error_1.5.7.log here.



  • @Sebastian-Roth, thanx for your answer.

    @Sebastian-Roth said in Unmodifiable DHCP-Server + Fog / Updating Database failed:

    @Tywyn said:

    Interface: ens160
    Server IP Address: 10.203.128.9
    Server Subnet Mask: 255.255.254.0

    Just to make sure as a very first step. Is this IP address already configured for interface ens160 on the Linux system itself?

    Yes it is. subnetmask is correct, as well.

    Updating Database…Failed!

    This can only happen if you run the installer with command line parameters. While this is fine I need to ask you which parameters did you use. Post the exact command you used here.

    As well, post more details on the Ubuntu version and FOG version you try to use.

    Ubuntu 18.04.4 LTS
    Fog is 1.5.7. I did a git pull and it said, it is up to date.

    First time I ran the install-script:

              2) Debian Based Linux (Debian, Ubuntu, Kubuntu, Edubuntu)
              3) Arch Linux
    
      Choice: [2]

     *** Detected a potential need to reinstall apache and php files.
     *** This will remove the /etc/php* and /etc/apache2* directories
     ***  and remove/purge the apache and php files from this system.
     *** If you're okay with this please type Y, anything else will
     ***  continue the installation, but may mean you will need to
     ***  remove the files later and make proper changes as 
     ***  necessary. (Y/N):

      FOG Server installation modes:
          * Normal Server: (Choice N) 
              This is the typical installation type and
              will install all FOG components for you on this
              machine.  Pick this option if you are unsure what to pick.
    
          * Storage Node: (Choice S)
              This install mode will only install the software required
              to make this server act as a node in a storage group

     * Here are the settings FOG will use:
     * Base Linux: Debian
     * Detected Linux Distribution: Ubuntu
     * Interface: ens160
     * Server IP Address: 10.203.128.9
     * Server Subnet Mask: 255.255.254.0
     * Server Hostname: fog03
     * Installation Type: Normal Server
     * Internationalization: 0
     * Image Storage Location: /images
     * Using FOG DHCP: No
     * DHCP will NOT be setup but you must setup your
     | current DHCP server to use FOG for PXE services.
    
     * On a Linux DHCP server you must set: next-server and filename
    
     * On a Windows DHCP server you must set options 066 and 067
    
     * Option 066/next-server is the IP of the FOG Server: (e.g. 10.203.128.9)
     * Option 067/filename is the bootfile: (e.g. undionly.kpxe)
    
    
     * Are you sure you wish to continue (Y/N) Y
    
     * Installation Started
    

    Then I noticed that installation of mariadb did not succeed. Reason was obviously, because I installed mysql-server before, because I did not know, that fog now installs everything by itself.

    So I did an apt remove mysql-server + apt remove mysql-client and started the fog-install-script with the -y commandline switch.
    ./installfog.sh -y

    Installation of mariadb and client went well then.

    Just to make sure as a very first step. Is this IP address already configured for interface ens160 on the Linux system itself? This is not something FOG will do for you! As well pay close attention to the subnet mask. While it is valid subnetting I just want to point to this before we go ahead. Make sure it’s correct.
