====Create a new LV and a new domain====
 +
First make sure that you have a decent configuration file with a bootable cd .iso file where you can install the OS. For this example we used the following configuration file:
 +
 
 +
*[[VmMrtSrv06-1.0|vmmrtsrv06-1.0.cfg]]
 +
 
 +
  > sudo lvcreate -n vmmrtsrv06 -L 20G dados01
 
  > cd /home/maretec/xen_configs
 
  > cd /home/maretec/xen_configs
−
  /home/maretec/xen_configs> xm new -F vmmrtsrv06-1.0.cfg

====let's add a data LV as a new PV in the domain====
 +
> sudo /sbin/lvcreate -n vmmrtsrv06-data -L 50G dados01
 +
> ls -l /dev/mapper

> sudo /usr/sbin/xm block-attach VMMRTSRV06 phy:/dev/mapper/dados01-vmmrtsrv06--data hdb:disk w
 +
> sudo /usr/sbin/xm reboot VMMRTSRV06
 +
 
 +
====Accessing the domain via a console with VNC====
 +
Access the domain with a [[VNC]] client, such as <goto>TightVNC</goto>. The domain console access port with VNC is '''192.168.20.125:5903'''. If running from the live cd, then proceed to install the distro. If the distro is already installed and you're not running from the live cd, then the linux distro is already installed and you can check the network ip so you can ssh. Open a new terminal and type the '''> ifconfig''' command. Read the ip number. In this case we have '''192.168.20.136'''. Then you can proceed to configure your new domain.

VmMrtSrv06 is a xen domain built in Maretec xen server composed of a 20GB LV and a temporarily device made of a dvd iso.

Objective/Function

This domain is meant to become a dedicated OpenDAP/Thredds/LAS and ftp server.

Architecture

http://content.screencast.com/users/GRiflet/folders/Jing/media/d90b157c-ec48-404f-a0d2-833d7350e89c/2009-02-03_2237.png

Logs/notes

Creation

From the maretec user at the MrtXnSrv, 192.168.20.125:

Create a new LV and a new domain

First make sure that you have a decent configuration file with a bootable cd .iso file where you can install the OS. For this example we used the following configuration file: 

> sudo lvcreate -n vmmrtsrv06 -L 20G dados01
> cd /home/maretec/xen_configs
/home/maretec/xen_configs> sudo /usr/sbin/xm new -F vmmrtsrv06-1.0.cfg
> sudo /usr/sbin/xm start vmmrtsrv06
> sudo /usr/sbin/xm sched-credit -d VMMMRTSRV06 -w 256 -c 150
> sudo /usr/sbin/xm sched-credit
sched-credit> Name                                ID Weight  Cap
Domain-0                             0    256    0
VMMRTSRV02                          17    256    0
VMMRTSRV03                                256    0
VMMRTSRV04                          19    256    0
VMMRTSRV05                          33    256    0
VMMRTSRV06                          36    256  150

let's add a data LV as a new PV in the domain

> sudo /sbin/lvcreate -n vmmrtsrv06-data -L 50G dados01
> ls -l /dev/mapper
> sudo /usr/sbin/xm block-attach VMMRTSRV06 phy:/dev/mapper/dados01-vmmrtsrv06--data hdb:disk w
> sudo /usr/sbin/xm reboot VMMRTSRV06

Accessing the domain via a console with VNC

Access the domain with a VNC client, such as <goto>TightVNC</goto>. The domain console access port with VNC is 192.168.20.125:5903. If running from the live cd, then proceed to install the distro. If the distro is already installed and you're not running from the live cd, then the linux distro is already installed and you can check the network ip so you can ssh. Open a new terminal and type the > ifconfig command. Read the ip number. In this case we have 192.168.20.136. Then you can proceed to configure your new domain.

Configuration

From the user user at the VmMrtSrv06, 192.168.20.136:

Update your distro

> su
> yum update

Add a new PV, a new VG and new LVs

> pvcreate /dev/sdb
> pvscan
> vgcreate -p 4 -v data /dev/sdb
> vgscan
> lvcreate -n opendap -L 40G data
> lvcreate -n ftp -L 5G data
> lvcreate -n http -L 1G data

Create filesystems and mount them

> mkfs -t ext2 /dev/data/opendap
> mkfs -t ext2 /dev/data/ftp
> mkfs -t ext2 /dev/data/http
> mkdir /opendap
> mkdir /http
> mkdir /ftp
> vim /etc/fstab
fstab> /dev/data/opendap       /opendap                ext2    defaults        0 0
fstab> /dev/data/http          /http                   ext2    defaults        0 0
fstab> /dev/data/ftp           /ftp                    ext2    defaults        0 0
> mount -a
> df

Configure users and groups

  • Use VNC then go to System-->Administration-->Users and groups
  • Make users the primary group of user user.
  • Create the group Maretec. Every user of this system should be applied to the group Maretec.
  • Create the user datamover. Make his primary group Maretec.

Configure permissions

Maintenance

Extending the LV size

Not done :(. Instead I'm starting over... (don't have access to the lvextend, fsck and resize2fd commands)

From the maretec user at the MrtXnSrv, 192.168.20.125: 

> sudo /sbin/lvextend -L+200G /dev/dados01/vmmrtsrv06-data
> sudo /sbin/fsck -f /dev/dados01/vmmrtsrv06-data
> sudo /sbin/resize2fs /dev/dados01/vmmrtsrv06-data

From the user user at the VmMrtSrv06, 192.168.20.136: 

> su
> pvextend
> fuser -m /dev/data/opendap
> ps aux | grep xxxx
> kill xxxx
> lvextend -L+150G /dev/data/opendap
> lvextend -L+45 /dev/data/ftp
> umount /dev/data/opendap
> umount /dev/data/ftp
> fsck -f /dev/data/opendap
> fsck -f /dev/data/ftp
> resize2fs /dev/data/opendap
> resize2fs /dev/data/ftp
> mount /dev/data/opendap
> mount /dev/data/ftp

Reboot...

Deleting pv, vg and lvs. Starting over.

From user user in the VmMrtSrv06 

> su
> vim /etc/fstab
fstab> #/dev/data/opendap      /opendap                ext2    defaults        0 0
fstab> #/dev/data/http         /http                   ext2    defaults        0 0
fstab> #/dev/data/ftp          /ftp                    ext2    defaults        0 0
> umount /opendap
> umount /http
> umount /ftp
> vgremove data
> pvremove -ff /dev/sdb

At this stage, all is done in VmMrtSrv06. You can proceed to shutdown.

From the user maretec in the MrtXnSrv: 

> sudo /usr/sbin/xm shutdown VMMRTSRV06
> sudo /usr/sbin/xm list -l VMMRTSRV06
> sudo /usr/sbin/xm block-detach VMMRTSRV06 hdb
> sudo /usr/sbin/xm list -l VMMRTSRV06
> sudo /sbin/lvcreate -n vmmrtsrv06-data01 -L 250G dados01
> ls -l /dev/mapper
> sudo /usr/sbin/xm block-attach VMMRTSRV06 phy:/dev/mapper/dados01-vmmrtsrv06--data01 hdb:disk w
> sudo /usr/sbin/xm start VMMRTSRV06

Changing the bridging between the LAN and the DMZ

Switching from LAN(eth0) to DMZ(eth1)

> sudo /usr/sbin/xm shutdown VMMRTSRV06
> sudo /usr/sbin/xm list -l VMMRTSRV06 > xen_configs/VMMRTSRV06_1.1.cfg
> sudo /usr/sbin/xm delete VMMRTSRV06
> vim xen_configs/VMMRTSRV06_1.1.cfg
06_1.1.cfg> remove all lines with uuid, status, long serial numbers, mac adresses ...
> cp xen_configs/VMMRTSRV06_1.1.cfg xen_configs/VMMRTSRV06_1.2.cfg
> vim xen_configs/VMMRTSRV06_1.2.cfg
06_1.2.cfg> (bridge eth1) 
06_1.2.cfg> :w
06_1.2.cfg> :q
> sudo /usr/sbin/xm new -F vmmrtsrv06-1.2.cfg
> sudo /usr/sbin/xm start VMMRTSRV06

Then, use TighVNC to enter the domain through console access as user:

  • System--> Administration--> Network--> New. It will open a wizard.
  • Ethernet connection--> Realtek (eth1)
  • Static ip-->192.168.21.20
  • Subnet mask-->255.255.255.0
  • Gateway--> 192.168.21.1
  • Save.
> su
> /sbin/service network restart
> /sbin/ifconfig
> /sbin/route -n

Finally, you need to ask Marco Reis from Conexa to configure the router firewall so it links the ports between the LAN firewall and the DMZ firewall (reverse tunneling, height port). You might as well ask also to open up ports 21, 20, 80, 443 and 8080.

Reconfiguring httpd

> vim /etc/httpd/conf/httpd.conf
httpd.conf> Listen 192.168.21.20:80
httpd.conf> :w
httpd.conf> :q
> /sbin/service httpd restart
> curl 192.168.21.20

Reconfiguring pure-ftpd

> ps aux | grep ftp
> kill pid ftpd
> /usr/sbin/pure-ftpd -E -l puredb:/etc/pure-ftpd/pureftpd.pdb &
> ftp localhost

Switching from DMZ(eth1) to LAN(eth0)

> sudo /usr/sbin/xm shutdown VMMRTSRV06
> sudo /usr/sbin/xm delete VMMRTSRV06
> sudo /usr/sbin/xm new -F vmmrtsrv06-1.1.cfg
> sudo /usr/sbin/xm start VMMRTSRV06

Then, use TighVNC to enter the domain through console access as user:

  • System--> Administration--> Network-->
  • Ethernet connection--> Realtek (eth0)
  • Static ip-->192.168.20.136
  • Subnet mask-->255.255.255.0
  • Gateway--> 192.168.20.1
  • Save.
> su
> /sbin/service network restart
> /sbin/ifconfig
> /sbin/route -n

Troubleshooting

  • The mouse in VNC won't work!
  • > sudo yum update on the client maching, then reboot.
