NFS

2008-04-08T09:06:01Z

Msokolov:

This page describes how to mount NFS partition inside container.

== NFS server ==
Currently OpenVZ kernel doesn't include kernel NFS server support. However you are still able to use user space [[NFS server inside container]].

== NFS client ==
=== Preparations ===
==== Prerequisites ====
You will need the following software:

# [http://openvz.org/download/utils#vzctl vzctl] version 3.0.13 or higher (do <code>vzctl --version</code>)
# [http://openvz.org/download/kernel/ kernel] version 2.6.18-028test006 or higher (2.6.18-028stab* will do), or any recent RHEL5-based or 2.6.20-based kernel.

Note: In all the kernels earlier than 028stab038, kernel NFS support can be given to a container by setting:

sunrpc.ve_allow_rpc = 1
fs.nfs.ve_allow_nfs = 1
kernel.ve_allow_kthreads = 1

This can be done by adding the above lines into /etc/sysctl.conf on the hardware node, and then running <code>sysctl -p</code>.

===== Debian Notes =====

Debian Etch still uses vzctl version 3.0.11 and so NFS client support is not yet available. Lenny presently has version 3.0.18.

==== Prepare the HN ====

For NFS mounts to work in the containers with the RHEL5-based kernels you must enable kernel threads in the container by setting "kernel.ve_allow_kthreads=1" in /etc/sysctl.conf

<pre>
# modprobe nfs
</pre>

==== Prepare the container ====
To allow a container use NFS filesystem, you will need to start it with "nfs" feature enabled. If the container is running while you set the --features "nfs:on", you will need to reboot it.
<pre>
# vzctl set 101 --features "nfs:on" --save
# vzctl start 101
</pre>

After this you may see nfs in <code>/proc/filesystems</code>
<pre>
# vzctl exec 101 cat /proc/filesystems
ext3
ext2
nodev rpc_pipefs
nodev proc
nodev nfs
nodev sysfs
nodev tmpfs
nodev devpts
</pre>

=== Mounting NFS ===
Make sure that packages nfs-utils and nfs-utils-lib or similar are installed in VE.

Assuming that you already have NFS server set up at <code>192.168.0.1:/nfs_pub</code> mounting will be simple
<pre>
# vzctl enter 100
# mkdir /nfs
# mount -t nfs 192.168.0.1:/nfs_pub /nfs
# cat /proc/mounts
simfs / simfs rw 0 0
proc /proc proc rw 0 0
sysfs /sys sysfs rw 0 0
devpts /dev/pts devpts rw 0 0
nfs /nfs nfs rw,vers=3,rsize=32768,wsize=32768,hard,proto=tcp,timeo=600,retrans=2,sec=sys,addr=192.168.0.1 0 0
</pre>

For more details on how to setup NFS mount see [http://nfs.sourceforge.net/nfs-howto/ar01s04.html NFS-client HOWTO]

=== Known issues ===
There are quite a few parameters in NFS, so sometimes it doesn't work due to misconfiguration. We've created a separate
page describing those situations: [[ NFS doesn't work ]]

Mount ISO image in a container

2008-03-31T09:40:43Z

Msokolov:

This page describes how to mount ISO image inside a container.

== Preparations ==
Configure FUSE in container as described in [[FUSE#VE_tuning]]

== Setup ==
Install packages <code>fuseiso</code> and <code>fuse</code> into container. Package names may vary on different Linux distributions.

* for Debian and Ubuntu, install <code>fuseiso</code> and <code>fuse-utils</code> packages (available in repository)
* for RHEL/CentOS 3/4/5, use DAG's packages [http://dag.wieers.com/rpm/packages/fuse-iso/ <code>fuse-iso</code>] and [http://dag.wieers.com/rpm/packages/fuse/ <code>fuse</code>]
* for Fedora 7/8, both <code>fuseiso</code> and <code>fuse</code> are available from the main/updates repo
* for Fedora 6, <code>fuse</code> is available from <code>extras</code> repo, use dries for [http://dries.ulyssis.org/rpm/packages/fuse-iso/info.html <code>fuse-iso</code>]

== Mounting ==
To mount an ISO image, do:

# fuseiso image.iso /mnt/disk

== See also ==
* [[FUSE]]

Msokolov:

This page describes how to mount ISO image inside a container.

== Preparations ==
Configure FUSE in container as described in [[FUSE]]

== Setup ==
Install packages 'fuseiso' and 'fuse' into container. Package names may vary on different Linux distributions.

F.e. for Debian and Ubuntu you should install 'fuseiso' and 'fuse-utils' packages (available in repository),

for RHEL3/4/5 and CentOS3/4/5 you may use DAG's packages '[http://dag.wieers.com/rpm/packages/fuse-iso/ fuse-iso]' and '[http://dag.wieers.com/rpm/packages/fuse/ fuse]'

Mount ISO image:

# fuseiso image.iso /mnt/disk

Package managers

2007-12-02T11:02:28Z

Msokolov:

With OpenVZ, you can run many different Linux distributions on a single box. One particular thing in which distributions differ is package management. This article summarizes how to perform various common package management tasks on a different distributions.

Template:KernelFlavorsInfo

2007-03-29T04:08:03Z

Msokolov:

You need only one kernel RPM so please choose the appropriate one depending on your hardware:

* On an x86 (i686) PC with more than 4 GB of RAM, use the <code>kernel-PAE</code> RPM.
* Otherwise, use the plain kernel RPM (<code>kernel</code>).

For more info, see [[Kernel flavors]].

</pre>
Make sure that VE's hostname is resolving correctly to VE's IP address. You can also add an appropriate record to /etc/hosts as a workaround.

Then go to http://www.swsoft.com/download/plesk8/ and download appropriate autoinstaller. CentOS 4.2 in this case.

Copy and install psa-autoinstaller-<VERSION>.rpm to VE#11

execute:
<pre>
# /usr/local/psa/bin/autoinstaller
</pre>
select version 8.0.1 and neccessary components.

after packages were downloaded selected components are installing:

<pre>
Start packages installation
-----skip-----

Congratulations!
Plesk has been successfully installed on your server.
To complete the system configuration, please proceed to URL:
https://plesk.local:8443/ or
https://127.0.0.1:8443/
Use the login name 'admin' and password 'setup'.

Further, use the following commands to start and stop Plesk:
"/etc/init.d/psa start" and
"/etc/init.d/psa stop" respectively.
