Expand Proxmox VM

These are the steps I took to expand the hard drive of a Windows 2003 server running on Proxmox
I found these steps here.

  1. Shutdown server
  2. Create backup
  3. Expand disk in my case it was to 60GB which is 64424509440 bytes which you divide by the bit size for the "seek" option (125829120):
  4. ~# cd /var/lib/vz/images/101
    ~# dd if=/dev/zero of=vm-101-disk-1.raw bs=512 count=0 seek=125829120

  5. Restart pvedaemon:
  6. ~# /etc/init.d/pvedaemon restart

  7. Add GParted live CD to virtual CD drive and boot server
  8. Resize NTFS partition with GParted interface
  9. Reboot server (Windows will run a constistency check because of the new disk size)

Glassfish 3.1.2 on Ubuntu 11.10

These are the steps I took to install Glassfish 3.1.2 on Ubuntu 11.10.

I should point out that I used a Proxmox KVM virtual server for this.  I first tried an OpenVZ virtual server but kept running into an error: "There is a process already using the admin port 4848 -- it probably is another instance of a GlassFish server."  After some googling I decided this error had something to do with the networking which is significantly different on OpenVZ than KVM so I abandoned the OpenVZ container and created a KVM virtual host.

These steps are a combination of two other guides in order to provide an internal Glassfish server that is password protected (here and here).

Before I began I installed Ubuntu 11.10 server (64-bit) on the Proxmox KVM virtual machine and updated to the latest available updates then backed-up the virtual machine.

  1. Install Java (I chose the natively available version of Java, openjdk):
  2. ~# sudo apt-get install openjdk-7-jdk
  3. Install the unzip utility (not included by default in Ubuntu 11.10):
  4. ~# sudo apt-get install unzip
  5. Create user and group to install and run Glassfish (I chose glassfish and glassfishadm):
  6. ~# sudo adduser --home /home/glassfish --system --shell /bin/bash glassfish
    ~# sudo groupadd glassfishadm
    ~# sudo usermod -a -G glassfishadm glassfish
  7. Change to glassfish user:
  8. ~# sudo su - glassfish
  9. Get Glassfish zip:
  10. ~# wget
  11. Unzip glassfish and move it to root of glassfish user home folder:
  12. ~# unzip
    ~# mv glassfish3/* .

    ~# rm -r glassfish3
    ~# rm
  13. Change owner and group of entire folder:
  14. ~# chown -R glassfish *
    ~# chgrp -R glassfishadm *
  15. Exit glassfish user:
  16. ~# exit
  17. Create script to start and stop Glassfish server at /etc/init.d/glassfish.  This script will use the glassfish user to start and stop the Glassfish instance so that it does not run as root:
  18. #!/bin/bash

    case "$1" in
        su - glassfish -c "/home/glassfish/bin/asadmin start-domain domain1"
        su - glassfish -c "/home/glassfish/bin/asadmin stop-domain domain1"
        su - glassfish -c "/home/glassfish/bin/asadmin stop-domain domain1"
        su - glassfish -c "/home/glassfish/bin/asadmin start-domain domain1"
        echo "usage: $0 {start|stop|restart}"


    exit 0
  19. Set script to run at boot:
  20. ~# sudo chmod u+x /etc/init.d/glassfish
    ~# sudo update-rc.d glassfish defaults
  21. Set admin password (default password for admin is blank):
  22. ~# sudo su - glassfish -c "/home/glassfish/bin/asadmin --user admin change-admin-password"
    Enter admin password> _

    Enter new admin password>
    Enter new admin password again>
    Command change-admin-password executed successfully.
  23. Set security on Glassfish:
  24. ~# sudo su - glassfish -c "/home/glassfish/bin/asadmin enable-secure-admin"
  25. Start the server:
  26. ~# sudo /etc/init.d/glassfish start

Redmine on Ubuntu 11.04 using MySQL

I decided to give Redmine a try and ran into a few issues using most of the guides out there to get it installed.  The guide that worked is below but be sure to install your mysql server (sudo apt-get install mysql-server) first.
