Configure OPENVZ Virtual Machine in Linux

In Linux, configure OPENVZ Virtual Machine-Linux Enterprise Application-Linux server application information. The following is a detailed description. Configure OPENVZ instances in Linux

We recommend that you use Fedora Core 4/5/3 or RHEL/CentOS 4.

1. Download the Installation File

According to your kernel version here: http://openvz.org/download/kernel/ download.
# Rpm-ihv vzkernel-name *. rpm

2. Modify the grub. conf file

Title OpenVZ (2.6.8-022stab029. 1) root (hd0, 0) kernel/vmlinuz-2.6.8-022stab029.1 ro root =/dev/sda5 initrd/initrd-2.6.8-022stab029.1.img

3. Modify the etc/sysyctl. conf file:

/Etc/sysctl. conf:
# On Hardware Node we generally need
# Packet forwarding enabled and proxy arp disabled
Net. ipv4.ip _ forward = 1
Net. ipv4.conf. default. proxy_arp = 0
# Enables source route verification
Net. ipv4.conf. all. rp_filter = 1
# Enables the magic-sysrq
Key kernel. sysrq = 1
# Net. ipv4.tcp _ ecn = 0
# We do not want all our interfaces to send redirects
Net. ipv4.conf. default. send_redirects = 1

4. If you have run iptables firewall and SELinux, disable and disable it first.

Edit/etc/sysconfig/selinux:
SELINUX = disabled.
Disable the iptables firewall.

5. Install OpenVZ Management Software

Depending on your version here: http://openvz.org/download/utils/ download.
# Rpm? Uhv vzctl *. rpm vzquota *. rpm vzpkg *. rpm

6. Restart VZ

#/Etc/init. d/vz start

7. Install the Template

# Rpm? Ihv vztmpl-fedora-core-3-1.0-2.noarch.rpm
# Vzpkgcache
Creating cache for fedora-core-3 OS template
Setting up install process
Packing cache file fedora-core-3.tar.gz...
Cache file fedora-core-3.tar.gz [130 M] created.

8. Create a non-zero ID for the Virtual Server

# Vzctl create 101
Creating VPS private area:/vz/private/101
VPS is mounted
Postcreate action done
VPS is unmounted
VPS private area was created

9. Set the parameter to zero.

# Vzctl set 101 -- hostname test101.my.org -- save
Hostname for VPS set: test101.my.org
Saved parameters for VPS 101
# Vzctl set 101 -- ipadd 10.0.186.1 -- save
Adding IP address (es): 10.0.186.1
Saved parameters for VPS 101
# Vzctl set 101 -- nameserver 192.168.1.165 -- save
File resolv. conf was modified
Saved parameters for VPS 101

10. Set the root user password

# Vzctl set 101 -- userpasswd root: test

11. Start the SSH daemon

# Vzctl exec 101 service sshd start

12. Start VPS

# Vzctl start 101
Starting VPS...
VPS is mounted
Adding IP address (es): 10.0.186.101 Hostname for VPS 101 set: test.my.org
VPS start in progress...

13. Load the Firewall

The firewall that was previously disabled must be loaded for security reasons.

# Vzctl set 101 -- iptables iptable_filter -- iptables ipt_length -- iptables ipt_limit -- iptables iptable_mangle -- iptables ipt_REJECT -- save
