      Server
      • FOG Version: 1.3.0-RC-18 (svn5991)
      • OS: Ubuntu 14.04.5 LTS (running as a VMware guest)
      Client
      • Service Version: NA
      • OS: NA
      Description

      I am attempting to upgrade my FOG server beyond its current RC-18 (to RC-22). While the installfog.sh script appears to run and complete as it normally does, it has resulted in two odd problems.

      First, it is no longer possible to start any processes for the five FOG services (FOGSnapinReplicator, FOGScheduler, FOGMulticastManager, FOGImageReplicator, FOGPingHosts). The processes can not be started from either 1) running the installfog.sh script, 2) rebooting the OS, or 3) manual attempts to stop/start or restart the services via cli (the listing below would also show the FOG processes if they were running).

      root@FogU1404T01:~# ps -ef | grep php
      root      15633      1  0 15:03 ?        00:00:00 php-fpm: master process (/etc/php5/fpm/php-fpm.conf)                    
      www-data  15636  15633  0 15:03 ?        00:00:00 php-fpm: pool www
      www-data  15637  15633  0 15:03 ?        00:00:00 php-fpm: pool www
      root      19272  19258  0 15:38 pts/14   00:00:00 grep --color=auto php
      

      Second, I have my fogsettings config file set to enable automated DB backups during FOG upgrades. This has been working fine for many months. However, the upgrade to 1.3.0-RC-22 produces an empty (zero byte) file for the automated DB backup. I can successfully create a good DB backup manually from the cli both before and after the step which updates the DB schema. This second issue is less of a concern since I know I can work around it manually as needed. So my main focus is on the first issue.

      I have attached the three files from FOG installer/updater …/bin/error_logs folder.
      The foginstall.log shows that the installfog.sh script appears to have run normally.
      0_1478999699458_foginstall.log

      But the presence of fog_err_1.3.0-RC-22.log is new to me (I haven’t seen it prior to RC-13).
      0_1478999647595_fog_err_1.3.0-RC-22.log
      In particular, that log contains:

      Considering dependency proxy for proxy_fcgi:
      Module proxy already enabled
      Module proxy_fcgi already enabled
      Module setenvif already enabled
      ERROR: Module php5-fpm does not exist!
      

      Here is the file fog_error_1.3.0-RC-22.log.
      0_1479000379589_fog_error_1.3.0-RC-22.log
      In particular, the tail of that log ends with:

       * Starting FOG Computer Imaging Solution: FOGMulticastManager
         ...done.
       * Starting FOG Computer Imaging Solution: FOGImageReplicator
         ...done.
       * Starting FOG Computer Imaging Solution: FOGSnapinReplicator
         ...done.
       * Starting FOG Computer Imaging Solution: FOGScheduler
         ...done.
       * Starting FOG Computer Imaging Solution: FOGPingHosts
         ...done.
       * Stopping NFS kernel daemon
         ...done.
       * Unexporting directories for NFS kernel daemon...
         ...done.
       * Exporting directories for NFS kernel daemon...
         ...done.
       * Starting NFS kernel daemon
         ...done.
      chmod: cannot access ‘/var/log/php*fpm’: No such file or directory
      

      It appears that there may be a problem with the script trying to modify non-existent log files. The relevant contents of the /var/log directory listing shows the following (Which would seem to explain the chmod failure above - “No such file or directory”. Perhaps correctable by changing to /var/log/php*fpm* or /var/log/php*fpm.log ?):

      -rw-r-----  1 mysql             adm         20 Oct 24 15:12 mysql.log.7.gz

      From what I can see, everything seems to point to php5-fpm (the PHP FastCGI Process Manager) as the potential cause of the problem. It doesn’t matter whether I try the FOG upgrade from a fully updated OS or not, or whether I try it from a snapshot prior to when I first see the fog_err_1.3.0-RC-22.log (going back to RC-13). The FOG upgrade always results in the same two problems of no startable FOG processes and an empty automated DB backup file.

      So for now, I am unable to upgrade FOG. And I am stuck functioning at 1.3.0-RC-18 which I am able to get back to using VMware snapshots. I’m hoping that the info I’ve provided can help identify a solution. And I appreciate any insight and assistance in finding one.

              Please try these steps:

              Edit the /opt/fog/.fogsettings file and remove the packages line.

              Edit the php_ver and php_verAdds lines to read as:

              php_ver="7.0"
              php_verAdds="-7.0"
              

              Remove the apache and php items from your installation:

              rm -rf /etc/{php,apache}*
              apt-get purge php5* libapache*php* apache*
              

              Rerun the fog installer.

              This should take a bit longer than you’re likely used to, but it should also make things MUCH easier for you.

                @Tom-Elliott OK, this is pretty much what I was expecting. So I’ve tried those steps and it looks good up until the point where installfog.sh fails at “Stopping web service”. Here is the foginstall.log which ends with:
                0_1479061190246_foginstall.log

                * Setting up fog user.........................................Already setup

                Here is the fog_error_1.3.0-RC-22.log which ends with:
                0_1479061317524_fog_error_1.3.0-RC-22.log

                * Stopping FOG Computer Imaging Solution: FOGScheduler

                  ...done.
                mysql stop/waiting
                mysql start/running, process 25774
                /etc/init.d/apache2: 64: .: Can't open /etc/apache2/envvars
                /etc/init.d/apache2: 76: .: Can't open /etc/apache2/envvars
                ERROR: APACHE_PID_FILE needs to be defined in /etc/apache2/envvars
                

                /etc/apache2/envvars does not exist. Here is a listing of the /etc/apache2 directory:

                root@FogU1404T01:/etc/apache2# lsa
                total 24
                drwxr-xr-x   4 root root  4096 Nov 13 09:53 .
                drwxr-xr-x 141 root root 12288 Nov 13 10:04 ..
                drwxr-xr-x   2 root root  4096 Nov 13 09:54 conf-available
                drwxr-xr-x   2 root root  4096 Nov 13 09:51 mods-available
                root@FogU1404T01:/etc/apache2# 
                

                I think this may be caused by old php5 processes still running as shown here:

                root@FogU1404T01:~# ps -ef | grep php
                root       1717      1  0 09:26 ?        00:00:00 php-fpm: master process (/etc/php5/fpm/php-fpm.conf)

                root      25547      1  0 10:04 ?        00:00:00 php-fpm: master process (/etc/php/7.0/fpm/php-fpm.conf)
                www-data  25550  25547  0 10:04 ?        00:00:00 php-fpm: pool www

                I could restore my snapshot and try again after making sure there are no php5 processes running. What do you think?

                  After rebooting the server I now have the FOG processes and the new php7 processes running as shown here.

                  But I don’t have any web GUI, obviously since the installfog.sh script never completed. So I’m going to first try rerunning the installer. And if that doesn’t work, I’ll restore my snapshot and try the steps again - this time making sure I don’t have any old php5 processes running.

                    @Tom-Elliott Rerunning the installer fails with the same results as before. Restoring the snapshot and trying the steps again after killing the three old php5 running processes also fails with the same results. Here are the logs from the last attempt with no php5 processes running.
                    1_1479073227092_foginstall.log
                    0_1479073227091_fog_error_1.3.0-RC-22.log

                    As with the other attempts, the directory /etc/apache2 only contains the subdirectories conf-available and mods-available. /etc/apache2/envvars does not exist.

                          @utopia Try:

                          rm -rf /etc/apache*; apt-get purge apache2

                          Then rerun installer.

                            @Tom-Elliott I suppose because it’s stopping this is the issue.

                            Maybe try:

                            touch /etc/apache2/envvars

                              I assumed that I would touch the envvars file after the apache2 package was reinstalled, then run the installer again after that if necessary. But since the package installation fails, I can’t get that far. Do you want the two log files from this?

                                @utopia I suppose you could do the manual installation of apache.

                                Or it just failed out because of the warning (the /var/www/html issue).

                                If you need to test it, I suppose you could do:

                                apt-get install apache2 -f
                                service apache2 start
                                service apache2 stop

                                  @Tom-Elliott “apt-get install apache2 -f” fails. However, aptitude was able to untangle the dependency trees. For your reference, the attached file shows a rough summary of the steps I took to sort it out.
                                  0_1479102893333_Fog_troubleshooting_161113d.txt

                                  Based upon the new php 7.0, I was able to successfully upgrade FOG from RC-18 to RC-22. This gave me running FOG processes and a functional GUI with the new apache2. Then, to test it out further, I upgraded again from RC-22 to RC-23. That successfully showed that I once again get automated DB backup files created during the FOG upgrade process which now do contain data (no longer zero byte size files). There are still some stray php5 processes which try to start and get killed during server bootup - which I will look into cleaning up. And I will be monitoring this server a bit more closely over the next few upgrades to make sure it remains stable.

                                  I do have a final related follow-up question. As the end of the attached file shows, the database backup files have different sizes depending upon whether they are created automatically during the FOG upgrade or created manually via the command line, such as “mysqldump --allow-keywords -x -v fog > fogbackup.sql”. I assume that both types of DB backup are equally useful for restoring or transferring the DB to either the same or a different FOG server - assuming of course that the target server is running the proper FOG version to match the DB backup file. Would that be a correct assumption that either method of creating the DB backup files is equally useful for restore or transfer?

                                  Lastly, I most certainly do THANK YOU for your insight in helping sort this out. Your assistance is VERY MUCH APPRECIATED!

                                    @utopia There is some variants in what’s going on for SQL backup. While the version that “automatically” creates a new backup is slightly larger, this is mostly just comments.

                                    I’ve seen some strange things in regards to Ubuntu in the past. The unfortunate part is that not all systems are the same. What you experienced does not mean everybody experiences. The only other thing I can think is ondrej changed how the repo is used relatively recently. Of note, php5-fpm is no longer proper, it’s supposed to be php5.6-fpm as described earlier in the posting. I’ve added this change for the working branch now so hopefully this will no longer be an issue.

                                    I don’t know what php5 items are still lingering, but I’d imagine you could remove them with aptitude just as well?
