            在Linux 下设置OPENVZ 实例

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

            1. 下载安装文件

            凭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. 若是你运行了iptables防火墙和SELinux  ,先关闭和克制 。

            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

            凭据您的版本在这里: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.为虚拟服务器建立一个非零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守护历程

            # 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  ,出于宁静思量这里还要加载


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