HyperVM

by on May.17, 2012, under Copas, Note

http://lxcenter.org/software/hypervm/hypervm-installation

Important Pre-Installation Step

Make sure that you open the ports 8888 and 8887 in the firewall. Otherwise you won’t be able to connect to HyperVM.

You have to disable selinux by editing /etc/sysconfig/selinux and changing the line to selinux=disabled and then running
# $ setenforce 0

HyperVM installation consists of downloading either the hypervm-install-master.sh or hypervm-install-slave.sh from http://download.lxcenter.org and execute it as root. It will download all the required files and do the complete installation on it’s own.

Install Commands

# $ setenforce 0
# $ wget http://download.lxcenter.org/download/hypervm/production/hypervm-install-master.sh
# $ sh ./hypervm-install-master.sh --virtualization-type=xen/openvz/NONE

You have to explicitly specify which virtualization type you want using the option –virtualization-type as either xen or openvz or NONE.

If you want to install hypervm on an existing system, just use virtualization-type=NONE, which will install just hyperVM components, and skip the virtualization components entirely.

When you run the command, you will presented with a menu from up2date, on which you can press .

HyperVM will currently install the openVZ/Xen kernel, but will not switch the default kernel to it. You will have to manually edit the /etc/grub.conf, and change the ‘default=1′ to ‘default=0′, and reboot the machine.

HyperVM supports the concept of multiple locations, and thus generally the question of harddisk partitioning is irrelevant. It is recommended to have a large / for openvz, since both /home and /vz will have files. You can just add another harddisk, mount it as a particular directory, and then add it to the list of locations. In other words, you can trivially distribute vpses across different harddisks/lvms. Also you can change the location of a vps from one harddisk to other from the CP itself. Go to vps home -> advanced -> change location.

You should never run any other control panel other than hyperVM on the host server. That will unncessarily introduce security risks, and in the case of openvz, since all the vps process are visible and accessible on the host server, starting and stopping of services on the host server will affect all the vpses too. If you need to run anything, create a special vps for it.

Once the machine boots back, just make sure you have the openVZ kernel by doing a ‘uname -a’, and after that you can connect to ‘http://machine-name:8888′, and you will be presented with a login screen – the password would be ‘admin’. Once you login, HyperVM will explicitly force you to change the password to something other than ‘admin’.

For those installing Xen, please read through the forum notes, and make sure that you meet all the requirements.

If you are installing hyperVM on a legacy operating system (Fedora 2, 3, 4), in an existing virtualization system, there are some things that you have to take care:

* Move /usr/bin/yum to /usr/bin/yum.old . HyperVM cannot use the old yum owing the fact that its configuration files are different from the latest version. If you move yum to yum.old, hyperVM will automatically use up2date.

* You can only install hyperVM, and installing of virtualization is not supported on legacy platforms. The legacy support is primarily meant to help existing installations to migrate to hyperVM. New installations are supported only on Centos-4.4 for openvz and fedora -6 for xen. So only –virtualization-type=NONE will work on the legacy platforms.

If you want to have a cluster, you have to run ‘hypervm-install-slave.sh’ in all the servers that you intend to make as slaves. Once ‘hypervm-install-slave.sh’ is completed, you can add the server from the ‘add server’ page in the master’s server page.

You will need to open port 8889 which is what’s used for communication between the master and slave. For file transfer, the slave will need to contact the master’s 8889 port, so you will need 8889 open on both master and the slave. All communication is fully encrypted and secure.

From then on, you can manage every aspect of Virtualization through our intuitive graphical interface.

===============================================================

UnInstall :

service hypervm stop
/etc/init.d/hypervm stop
chkconfig hypervm off

rpm -e lxphp lxzend lxlighttpd
rm -rf /usr/local/lxlabs/

Backup Switch Cisco

by on Dec.06, 2011, under Belajar IT, Keseharian, Ngoprek, Note

Kadang kita suka males kalo mau backup switch, kalau hanya satu atau dua switch cisco sih ga begitu masalah.. kalau ada lebih dari 20 switch ? pasti merepotkan juga kan….

Nah karena dasar itu saya coba iseng-iseng bikin program asal-asalan, sebenernya ni program cuman buat ngebantu kita meng exekusi beberapa printah di cisco, seperti memasukkan user name, password, enable password, password enable, printah-printah backup seperti :

copy runing-config tftp:

copy vlan.dat tftp:

copy config.text tftp:

Nah untuk membuat tools ini memerlukan beberapa program yaitu :

1. Telnet client ( by default sudah ada pada windows anda, kecuali windows 7 harus di aktifkan program telnet cliant-nya )

2. AutoIT ( bisa di download di sini )

3. TFTP-Server ( bisa di download di sini )

Setelah Telnet Client , AutoIT dan TFTP-Server  di install sekarang ke proses selanjutnya yaitu pembuatan tools-nya contoh scrip-nya :

Address list routing OIXP APJII dan MCSIX

by on Jul.16, 2011, under Belajar IT, Ngoprek, Note

Update per Tgl 19 Oktober 2011

bagi temen-temen yang butuh address-list guna pembagian Bandwidth IIX, OIXP dan MCSIX, silakan download

Address-list MCSIX , OIXP dan APJII

and langsung aja upload ke dua file tersebut ( mcsix.rsc dan nice.rsc ) ke mikrotik => new terminal =>

/import mcsix.rsc

/import nice.rsc

Oh iya.. di dalam address-list tersebut untuk penamaan MCSIX adalah mcsix dan untuk OIXP+APJII adalah nice.

kalo mau generate sendiri silakan pake script ini :

:local bhomert [/ip route pr count-only];
:local bho 0;
:local mer 0;
:local mert;
:for bho from=0 to=$bhomert step=1 do={
:set mert [/ip route get $bho dst-address]
:if ($mer = 0) do={
/ip firewall address-list add list=nice address=$mert;}
}

nah kalo mau ngejalanin tinggal lewat telnet.. jangan lewat winbox :) suka ga dapet full, oh iya.. sebelum-nya naikin dulu bgp / ospf buat dapetin prefix dari router mcsix dan router iix ( oixp+apjii )

[evan@mix-prefix] /routing bgp peer> print  detail status
Flags: X – disabled, E – established
0 E name=”ke-MIX” === CUT ====
uptime=11h5m14s prefix-count=19813 updates-sent=9699

1 E name=”ke-IIX” === CUT ====
uptime=14h19m43s prefix-count=8584 updates-sent=41719

CHMOD

by on May.31, 2011, under Belajar IT, Note

chmod = change file modes

Permissions Owner Group Others
chmod 777 rwx rwx rwx
chmod 666 rw- rw- rw-
chmod 555 r-x r-x r-x
chmod 444 r– r– r–
chmod 333 -wx -wx -wx
chmod 222 -w- -w- -w-
chmod 111 –x –x –x
chmod 000

After chmoding a file you can use ls -l to view the permissions.

Using the above chart you can combine permissions.

chmod 644 = rw-r–r–

chmod 731 = rwx-wx–x

Owner = user that created the file

Group = users in the same group as owner

Others = the rest of the users on the system

HOWTO: Backup files with tar

by on Feb.09, 2011, under Belajar IT, Copas, Note

Posted by Jason on Sunday July 01, @12:37PM
from the It’s-Sticky-Fun-Fun-Fun dept.
TAR is the Unix Tape ARchive utility. It can be used to either store data on a streaming tape device like a DAT drive, or store files in what is commonly called a tarball file- somewhat like a pkzip file, only compression is optional.
Source

[The basics]

In these examples, I will use the following file structure: a top level directory called DIR1 containing the files picture.jpg, document.doc and database.db.

DIR1/

DIR1/picture.jpg
DIR1/document.doc
DIR1/database.db

[Creating a tarball]

If we were in the directory DIR1 and wanted to backup all the files to a tarball called backup.tar, we could issue this command:

$ tar cvf backup.tar .

./
picture.jpg
doucment.doc
database.db
tar: backup.tar is the archive; not dumped

Note:
c=create (an archive)
v=verbose (just because)
f=filename (the name of our tarball)
.=current directory (what’s going to be backed up)

Also worth mentioning is that by default tar is recursive- meaning it will back up all files and subdirectories recursively unless you otherwise specify with the n flag (non-recursive)

[Displaying the Contents of a Tarball]

The current directory will now contain a file called backup.tar. To display the contents of the tarball file, we could issue this command:

$ tar tvf backup.tar

drwxr-xr-x root/gci 0 Jun 29 10:10 ./
-rw-r–r– root/gci 1 Jun 29 10:10 picture.jpg
-rw-r–r– root/gci 1 Jun 29 10:10 document.doc
-rw-r–r– root/gci 1 Jun 29 10:10 databse.db

Note:
t=table of contents (list)
v=verbose (display all info)
f=filename (backup.tar)

[Extracting Data from a Tarball]

To extract the entire contents of the tarball to the current directory, we can type:

$ tar xvf backup.tar

./
picture.jpg
doucment.doc
database.db

Note:
x=extract
v=verbose
f=filename (backup.tar)

To extract only the picture.jpg file from the archive, type the following command:

$ tar xvf backup.tar picture.jpg

Alternatively, you can use wild cards in either the creation or extraction of a tarball. To extract all jpg files from our archive, we can use a command like this:

$ tar xvf backup.tar *.jpg

[Using Compression]

If you would also like to add compression to your tarballs, you can combine the gzip utility with tar on the command line by adding the z switch to the command. Usually when this is done, we change the suffix of our tarball filename from .tar to either .tgz or .tar.gz. This will let whoever sees the file know that it is a gzipped tarball.

$ tar zcvf tarball.tgz .

Note:
z=gzip compression
c=create
v=verbose
f=filename (backup.tgz)
.=current directory (what to backup)

[Permissions with tar]

If you would like to preserve the permissions of the files you backup, use the p option with the tar command. This will save the uid, gid as well as the specific permission attributes of the files (read, write, execute etc.)

$ tar pzcvf tarball.tgz .

You should also use the p option with the tar extraction command:

$ tar pxvf tarball.tgz .

[Using tar with a Tape Drive]

I use tar in conjunction with my Seagate DAT drive. If you issue any of the previous commands in this HOW-TO without the f option and a tarball filename, you will find that tar will default to writing the files to the device /dev/rsa0 (raw sequential access device 0). Basically this is your first SCSI tape drive. If you have more than one tape drive you would like to use, you can issue the f option and the device name (rsa0, rsa1 etc.) of your specific tape drive instead of a filename.

Examples:
Backing up the current directory to Tape:

$ tar cv . <- default tape drive (rsa0)

$ tar cvf /dev/rsa1 . <- second tape drive (rsa1)

Restore files from Tape:

$ tar xv .
$ tar xvf /dev/rsa1

So, there are the basics of tar. If you would like more information on the tar command, try the man pages.

man tar

Alhamdulillah,

Hari ini hosting web evan.or.id susah mulai aktif lagi dan saya sengaja di hostingkan ke salah satu web hosting di indonesia yaitu MWN

Kenapa ga bikin server hostingan sendiri ?
Ribet boss, ia kalo servernya punya sendiri.. kan enak.. nah kalo servernya milik kantor ? ia kalo kantornya sendiri, la kalo kita cuman gawe di kantor orang ? kalo kita pindah kantor mindahin lagi dah data-datanya…

Jadi cari aman aja.. biar ga repot kalo mau pindah-pindah hostingan

Nah.. kalo mau ikutin ide kita.. silakan klik ini aja www.masterwebnet.com
