Hm2k: improved tar based backup/restore

{{wikify}}

[[Category:Templates]]

To create a CentOS 5 minimal template from centos-4-i386-minimal,
follow these steps:

==Create the container==

Create a container using centos-4-i386-minimal and set a valid nameserver:
<pre>
vzctl create $CTID --ostemplate centos-4-i386-minimal --config CONFIG_TEMPLATE --ipadd container_IP --hostname temp
vzctl set $CTID --nameserver NAMESERVER_IP --save
</pre>

==Install centos-5-release packages==
Use <code>vzctl exec</code> to execute the rpm install command on the container:

<pre>
vzctl exec $CTID rpm -Uvh http://mirror.centos.org/centos/5/os/i386/CentOS/centos-release-notes-5.6-0.i386.rpm \ http://mirror.centos.org/centos/5/os/i386/CentOS/centos-release-5-6.el5.centos.1.i386.rpm
</pre>
Note: centos-release-5 depends on notes-package, start with that one.

==Backup dev==

Backup the container /dev/ directory, as initscripts needs udev and will remove vzdev you'll need the backup:

<pre>
tar -cf $CTID.dev.tar -C /vz/private/$CTID dev
</pre>

==Install initscripts package==

Install initscripts package (forced and with no deps), as per below:

<pre>
vzctl exec $CTID rpm -Uvh http://mirror.centos.org/centos/5/os/i386/CentOS/initscripts-8.45.33-1.el5.centos.i386.rpm --force --nodeps
</pre>

Note: If the "transfer failed", go to the [http://mirror.centos.org/centos/5/os/i386/CentOS/ CentOS5 mirror] and find the latest initscripts rpm and use that instead.

==Update conf file==

Edit /etc/vz/conf/$CSID.conf and replace
<pre>
OSTEMPLATE="centos-4-i386-minimal"
</pre>
with
<pre>
OSTEMPLATE="centos-5-i386-minimal"
</pre>

Alternatively, use the 'sed' command to replace it:
<pre>
sed -i 's#OSTEMPLATE="centos-4#OSTEMPLATE="centos-5#g' /etc/vz/conf/$CTID.conf
</pre>

==Copy existing template==

Copy existing template from:

<pre>
/vz/template/centos/4
</pre>
to
<pre>
/vz/template/centos/5
</pre>

==Update yum.conf==

In /vz/template/centos/5/i386/config/yum.conf change mirrors to CentOS 5

Using sed:

<pre>
sed -i 's#centos4#centos5#g' /vz/template/centos/5/i386/config/yum.conf
sed -i 's#CentOS 4#CentOS 5#g' /vz/template/centos/5/i386/config/yum.conf
sed -i 's#centos/4/#centos/5/#g' /vz/template/centos/5/i386/config/yum.conf
</pre>

==Upgrade container packages==

db-version will complain, so delete the conflicting database first:
<pre>
rm -fr /vz/root/$CTID/var/lib/rpm/__*
</pre>

Now run vzyum to upgrade the contain packages:
<pre>
vzyum $CTID upgrade
</pre>

===Troubleshooting===

If you get this error:

<pre>
Error: Missing Dependency: python-abi = 2.3 is needed by package python-elementtree
</pre>

and/or
<pre>
warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID e8562897
Public key for libsepol-1.15.2-3.el5.i386.rpm is not installed
</pre>

You need to run the following before trying again:

<pre>
vzctl exec $CTID rpm -e --justdb python-elementtree --nodeps
vzctl exec $CTID rpm --import http://mirrors.kernel.org/centos/RPM-GPG-KEY-CentOS-5
</pre>

==Test your VE==
Check you can enter your VE:
<pre>
vzctl enter $CTID
</pre>

All went OK? Exit the VE:
<pre>
exit
</pre>

===Troubleshooting===

<pre>
Unable to open pty: No such file or directory
</pre>
If you see errors like this, see the [[VPS_enter_failed]] article.

==Stop your VE==
<pre>
vzctl stop $CTID
</pre>

==Restore dev==

This will replace the new /dev/ with the old one:
<pre>
mv /vz/private/$CTID/dev /vz/private/$CTID/dev.old
tar -xvf $CTID.dev.tar -C /vz/private/$CTID
</pre>

== Remove container IP ==
<pre>
vzctl set $CTID --ipdel all --save
</pre>

==Create the template==
<pre>
cd /vz/private/$CTID
tar --numeric-owner -zcf /vz/template/cache/centos-5.5-i386-minimal.tar.gz .
</pre>

To create a CentOS 5 minimal template from centos-4-i386-minimal,
follow these steps:

==Create the container==

Create a container using centos-4-i386-minimal and set a valid nameserver:
<pre>
vzctl create $CTID --ostemplate centos-4-i386-minimal --config CONFIG_TEMPLATE --ipadd container_IP --hostname temp
vzctl set $CTID --nameserver NAMESERVER_IP --save
</pre>

== Enter container ==
<pre>
vzctl enter $CTID
</pre>

==Install centos-5-release packages==

<pre>
rpm -Uvh http://mirror.centos.org/centos/5/os/i386/CentOS/centos-release-notes-5.6-0.i386.rpm \ http://mirror.centos.org/centos/5/os/i386/CentOS/centos-release-5-6.el5.centos.1.i386.rpm
</pre>
Note: centos-release-5 depends on notes-package, start with that one.

==Backup dev==

Backup your /dev/ directory, as initscripts needs udev and will remove vzdev you'll need the backup:

<pre>
tar -cf dev.tar ./dev
</pre>

==Install initscripts package (forced and with no deps)==

<pre>
rpm -Uvh http://mirror.centos.org/centos/5/os/i386/CentOS/initscripts-8.45.33-1.el5.centos.i386.rpm --force --nodeps
</pre>

Note: If the "transfer failed", go to the [http://mirror.centos.org/centos/5/os/i386/CentOS/ CentOS5 mirror] and find the latest initscripts rpm and use that instead.

==Exit from container==

To create a CentOS 5 minimal template from centos-4-i386-minimal,
follow these steps:

==Create a container using centos-4-i386-minimal and set a valid nameserver==
<pre>
vzctl create $CTID --ostemplate centos-4-i386-minimal --config CONFIG_TEMPLATE --ipadd container_IP --hostname temp
vzctl set $CTID --nameserver NAMESERVER_IP --save
</pre>

== Enter container ==
<pre>
vzctl enter $CTID
</pre>

==Install centos-5-release packages==

rpm -Uvh http://mirror.centos.org/centos/5/os/i386/CentOS/centos-release-notes-5.6-0.i386.rpm \
http://mirror.centos.org/centos/5/os/i386/CentOS/centos-release-5-6.el5.centos.i386.rpm

Note: centos-release-5 depends on notes-package, start with that one.

==Backup your /dev/, since initscripts need udev and will remove vzdev you'll net the backup==
<pre>
tar -cf dev.tar ./dev
</pre>

==Install initscripts package (forced and with no deps)==

<pre>
rpm -Uvh http://mirror.centos.org/centos/5/os/i386/CentOS/initscripts-8.45.33-1.el5.centos.i386.rpm --force --nodeps
</pre>

Note: If the "transfer failed", go to the [http://mirror.centos.org/centos/5/os/i386/CentOS/ CentOS5 mirror] and find the latest initscripts rpm and use that instead.

==Exit from container==
<pre>
exit
</pre>

==Update conf file==

Edit /etc/vz/conf/$CSID.conf and replace
<pre>
OSTEMPLATE="centos-4-i386-minimal"
</pre>

</pre>

==Copy existing template==

Copy existing template from:

<pre>
/vz/template/centos/4
</pre>
to
<pre>
/vz/template/centos/5
</pre>

==Update yum.conf==

Hm2k: Better formatting

== Problem ==

When you issue the following command you get an error:
[root@server ~]# vzctl enter 101
enter into CT 101 failed
Unable to open pty: No such file or directory

== Solutions ==

=== Using strace ===

You can use [http://linux.die.net/man/1/strace strace] to analyse the command further:
<pre>
# strace -ff vzctl enter 101
....
fstat64(...st_mode=S_IFCHR|0620, st_rdev=makedev(136, 0)...) fail
....
</pre>

Recompile the kernel with the following option:
CONFIG_LEGACY_PTYS=y

=== LEGACY_PTYS ===

==== Temporary fix ====
''Note: This is a temporary fix so you can enter the VE.''

* Create the LEGACY_PTYS devices:

vzctl exec 101 /sbin/MAKEDEV tty
vzctl exec 101 /sbin/MAKEDEV pty
vzctl enter 101

==== Permanent fix with udev ====
* For a permanent fix with udev, you will need to force udev to make LEGACY_PTYS:

cat > /etc/udev/makedev.d/51-udev.nodes
# These device have to be created manually
tty0
tty1
tty2
tty3
....
ttyp0
ttyp1
ttyp2
ttyp3
....
ptyp0
ptyp1
ptyp2
ptyp3
....

==== Permanent fix without udev ====
* Alternatively, you can disable udev:

Edit the ''/etc/rc.d/rc.sysinit'' file and comment out the ''/sbin/start_udev'' line

Or you can run the following command:

sed -i 's|/sbin/start_udev|#/sbin/start_udev|g' /etc/rc.d/rc.sysinit

''Warning'' Updates to the package which owns this file may revert your changes.

''Note'' This was tested with CentOS VE.

=== Debian only ===

* Enter the VE manually
CTID=101
vzctl exec $CTID "mount -t devpts devpts /dev/pts"
vzctl enter $CTID

* Remove udev using apt
CTID=101
vzctl exec $CTID apt-get remove udev
vzctl restart $CTID

rpm -Uvh http://mirror.centos.org/centos/5/os/i386/CentOS/centos-release-5-5.el5.centos.i386.rpm
</pre>
Note: centos-release-5 depends on notes-package, start with that one.
