OpenVZ provides a low overhead alternative to Xen.
To get started we need to add the OpenVZ software repository. Type the following commands.
> cd /etc/yum.repos.d
> wget http://download.openvz.org/openvz.repo
Edit openvz.repo and enable the developement kernel.
1. First lets install the kernel. Type the following.
> yum --disablerepo=core --disablerepo=updates install kernel-smp
2. Replace /etc/sysctl.conf with the following.
# Kernel sysctl configuration file for Red Hat Linux # # For binary values, 0 is disabled, 1 is enabled. See sysctl(8) and # sysctl.conf(5) for more details. # Controls IP packet forwarding net.ipv4.ip_forward = 1 net.ipv4.conf.default.proxy_arp = 0 # Controls source route verification net.ipv4.conf.default.rp_filter = 1 # Do not accept source routing net.ipv4.conf.default.accept_source_route = 0 # Controls the System Request debugging functionality of the kernel kernel.sysrq = 1 # Controls whether core dumps will append the PID to the core filename. # Useful for debugging multi-threaded applications. kernel.core_uses_pid = 1 # Controls the use of TCP syncookies net.ipv4.tcp_syncookies = 1 # we do not want all our interfaces to send redirects net.ipv4.conf.default.send_redirects = 1 net.ipv4.conf.all.send_redirects = 0
3. Reboot the server. Be sure to boot the OpenVZ kernel.
4. Lets install some needed tools.
> yum install vzctl vzquota
5. Finally lets start OpenVz.
> /sbin/service vz start
1. First we need to install some tools.
> yum install vzpkg vzyum vzrpm43-python vzrpm44-python
2. Now install the template metadata.
> yum install vztmpl-fedora-core-5
3. Install the repository cache.
> vzpkgcache fedora-core-5-default
That's the complete setup. Now you can create your Virtual servers. Your best bet is to use the tools we've installed.
