Install and configure VMware Server on Linux

1. Please make sure latest VMware server first at Vmware's site and get latest version of it. Furthermore, register serial number first on the page on VMware, it's necessary to input during installation.
[root@ns ~]# wget http://download3.vmware.com/software/vmserver/VMware-server-2.0.1-156745.x86_64.rpm

[root@ns ~]# rpm -Uvh VMware-server-2.0.1-156745.x86_64.rpm

Create and configure VPS on Linux OpenVZ

1.Create VPS. VPS means Virtual Private Server, it's the GuestOS in short. I installed CentOS 4 for VPS because there is no template of CentOS 5 for VPS.

Linux CentOS 5 On VMWare Server: Installing VMWare Tools

A few weeks ago I’ve made a few posts on installing Linux CentOS 5 on a VMware Server. Well today I realized I didn’t post the part about installing the VMware Tools. These tools allow you to increase your virtual machine’s performance and capabilities.

Prior to installing the VMware Tools, there are a few things you want to do. The first step would be to install the kernel header files and a C compiler:

# yum install gcc gcc-c++ kernel-devel

The second thing would be to create a symbolic link pointing to your kernel header files:

# ln –s /usr/src/kernels/[your kernel version] /usr/src/linux

Now you’re ready to install the VMware Tools. From the VMware Server Console (with your virtual machine running), click on “VM => Install VMware Tools…”. Nothing is supposed to be happening at this point, it’s just like you inserted a virtual CD. From the command line, mount the cdrom drive, copy the installation files to a directory on your virtual hard drive and untar them:

# mount /dev/cdrom /mnt/cdrom
# cd /mnt/cdrom
# cp VMwareTools-[version].tar.gz /tmp
# cd /tmp
# umount /mnt/cdrom
# tar zxf VMwareTools-[version].tar.gz

Execute the VMware Tools installation script:

# cd /tmp/vmware-tools-distrib
# ./vmware-install.pl

Go through the installation and answer all the questions. I’ve left every settings to its default value.

When you’re done, simply reboot your virtual machine. I’ve had a little problem with X as it wouldn’t start upon reboot. I just used the X configuration wizard (which launched automatically) to make some adjustments, rebooted the VM again and everything worked fine.

OpenVZ On CentOS 5.4 installation and configuration

This article will describe how to create OpenVZ container in CentOS 5.4. With OpenVZ you can create multiple Virtual Private Servers (VPS) on same hardware machine and running them simultaneously and efficiently.

OpenVZ is the open-source branch of Virtuozzo, a commercial virtualization solution widely used by hosting providers. The OpenVZ kernel patch is licensed under GPL license, and the user-level tools are under the QPL license.

As there are many ways of achieving this goal, I’d keep this howto as smart as possible. In the following days, I’d create similar posts on Xen / Vserver, please keep a close eye on my planet.

1, Install OpenVZ

In order to install OpenVZ, we need to add the OpenVZ repository to yum, this would also help us keep the kernel up-to-date:

cd /etc/yum.repos.d
wget http://download.openvz.org/openvz.repo
rpm --import http://download.openvz.org/RPM-GPG-Key-OpenVZ

The repository contains a few different OpenVZ kernels (you can find more details here: http://wiki.openvz.org/Kernel_flavors), or with this command “yum search ovzkernel“.

Pick one of them and install it as follows:

yum install ovzkernel

This should automatically update the GRUB bootloader as well. An example is listed below”

cat /boot/grub/menu.lst
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
#          initrd /initrd-version.img
#boot=/dev/sda
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.18-128.2.1.el5.028stab064.7)
 root (hd0,0)
 kernel /vmlinuz-2.6.18-128.2.1.el5.028stab064.7 ro root=LABEL=/
 initrd /initrd-2.6.18-128.2.1.el5.028stab064.7.img

2, Pre-adjustings before the installation

Now we install some OpenVZ user tools:

yum install vzctl vzquota

Open /etc/sysctl.conf and make sure that you have the following settings in it:

cat /etc/sysctl.conf

net.ipv4.ip_forward = 1
net.ipv4.conf.default.proxy_arp = 0
net.ipv4.conf.all.rp_filter = 1
kernel.sysrq = 1
net.ipv4.conf.default.send_redirects = 1
net.ipv4.conf.all.send_redirects = 0
net.ipv4.icmp_echo_ignore_broadcasts=1
net.ipv4.conf.default.forwarding=1

The following step is important if the IP addresses of your virtual machines are from a different subnet than the host system’s IP address. If you don’t do this, networking will not work in the virtual machines!

Open /etc/vz/vz.conf and set NEIGHBOUR_DEVS to all, the modified entry is like this “NEIGHBOUR_DEVS=all“. SELinux needs to be disabled, you can do it by making changes on its config file /etc/sysconfig/selinux. Finally, reboot the system, and then your new OpenVZ kernel should show up:

[root@server1 ~]# uname -r
2.6.18-128.2.1.el5.028stab064.7

3, Create a Virutal Server

Before we can create virtual machines with OpenVZ, we need to have a template for the distribution that we want to use in the virtual machines in the /vz/template/cache by default. New virtual machines will be created from these templates. A list of precreated templates is available here.

I want to use CentOS 5 in my virtual machines, so I download a CentOS 5 template:

cd /vz/template/cache
wget http://download.openvz.org/template/precreated/contrib/centos-5-i386-default.tar.gz

To set up a VPS from the default CentOS 5 template, run:

vzctl create 211 --ostemplate centos-5-i386-default --config vps.basic

The 211 must be uniqe and each virtual machine must have its own ID. You can use the last part of the VPS’s IP address for it. For example, if the virtual machine’s IP address is 192.168.0.211, you use 211 as the ID.

4, Common controls on OpenVZ

If you want to have the vm started at boot, run:

vzctl set 211 --onboot yes --save

To set a hostname and IP address for the vm, run:

vzctl set 211 --hostname test.example.com --save
vzctl set 211 --ipadd 192.168.0.211 --save

Next we set the number of sockets to 120 and assign a few nameservers to the vm:

vzctl set 211 --numothersock 120 --save
vzctl set 211 --nameserver 85.17.150.123 --nameserver 83.149.80.123 --nameserver 145.253.2.75 --save

Instead of using the vzctl set commands, you can directly edit vm’s configuration file which is stored in the directory/etc/vz/conf. If the ID of the vm is 211, then the configuration file is /etc/vz/conf/211.conf.

In order to start the vm, run “vzctl start 211″, to set a root password for the vm, run “vzctl exec 211 passwd”. Now You can either connect to the vm via SSH (e.g. with PuTTY), or login through console directly as follows:

vzctl enter 211

To leave the vm’s console, type “exit”, to stop a vm, run “vzctl stop 211“, to restart a vm, run “vzctl restart 211“.

To delete a vm from the hard drive (it must be stopped before you can do this), run “vzctl destroy 211“.

5, Check VM Status

To get a list of your vms and their statuses, run “vzlist -a” like this:

[root@server1 cache]# vzlist -a
      VEID      NPROC STATUS  IP_ADDR         HOSTNAME
       211         18 running 192.168.0.211   test.example.com

To find out about the resources allocated to a vm, run like follows:

[root@server1 cache]# vzctl exec 211 cat /proc/user_beancounters
Version: 2.5
       uid  resource           held    maxheld    barrier      limit    failcnt

The failcnt column is very important, it should be only zeros; if not, means that the vm needs more resources than currently allocated. Open the vm’s configuration file in /etc/vz/conf and raise the appropriate resource, then restart it.

To find out more about the vzctl command, run “man vzctl”. If you faced any issues during the installation, please create a thread and show your errors  in the sub forum virtualization at admon community.
