在Linux 下配置OPENVZ 实例

推荐使用Fedora Core 4/5/3 或者RHEL/CentOS 4。

1. 下载安装文件

根据您的内核版本在这里:http://openvz.org/download/kernel/ 下载。

# rpm -ihv vzkernel-name*.rpm

2.修改grub.conf 文件

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.修改、etc/sysyctl.conf文件:

/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. 假如你运行了iptables防火墙和SELinux,先关闭和禁止。

编辑/etc/sysconfig/selinux:

SELINUX=disabled。

另外还要关闭iptables防火墙。

5.安装OpenVZ治理软件

根据您的版本在这里:http://openvz.org/download/utils/ 下载。

# rpm –Uhv vzctl*.rpm vzquota*.rpm vzpkg*.rpm

6.重新启动VZ

# /etc/init.d/vz start

7.安装模板

# 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 [130M] created.

8.为虚拟服务器创建一个非零ID

# 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.设置为零参数

# 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.设置root用户口令

# vzctl set 101 --userpasswd root:test

11.启动SSH守护进程

# vzctl exec 101 service sshd start

12.启动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.加载防火墙

前面关闭的防火墙,出于安全考虑这里还要加载

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