There are a few tutorials out there on installing OpenVZ in CentOS 5.3. Here are the steps I use to install OpenVZ on a brand new installation of CentOS 5.3:
Note: this tutorial / walkthrough is for use 64 bit only
- Update the box via yum
- Install the OpenVZ Repository and grab the GPG key
- Install OpenVZ
- Install OpenVZ Controller and Quota system
- Configure the local system for the OpenVZ kernel
- Update OpenVZ’s ARP Settings
- Disable SELINUX
- Reboot
yum -y update cd /etc/yum.repos.d wget http://download.openvz.org/openvz.repo rpm --import http://download.openvz.org/RPM-GPG-Key-OpenVZ yum -y install ovzkernel.x86_64 yum -y install vzctl.x86_64 vzquota.x86_64
Now; we need to configure the sysctl.conf file for OpenVZ
perl -pi -e 's/net\.ipv4\.ip_forward = 0/net\.ipv4\.ip_forward = 1/' /etc/sysctl.conf perl -pi -e 's/kernel\.sysrq = 0/kernel\.sysrq = 1/' /etc/sysctl.conf echo -e "\n\nnet.ipv4.conf.default.proxy_arp = 0\nnet.ipv4.conf.all.rp_filter = 1\nnet.ipv4.conf.default.send_redirects = 1\nnet.ipv4.conf.all.send_redirects = 0\nnet.ipv4.icmp_echo_ignore_broadcasts=1\nnet.ipv4.conf.default.forwarding=1\nkernel.ve_allow_kthreads=1\n" >> /etc/sysctl.conf perl -pi -e 's/NEIGHBOUR_DEVS=detect/NEIGHBOUR_DEVS=all/' /etc/vz/vz.conf
Disable SELINUX
vi /etc/sysconfig/selinux
Reboot the machine
reboot
