解析Linux配置OPENVZ的知識
很多人在學習Linux,可以看出Linux現(xiàn)在的地位越來越重要,你了解Linux系統(tǒng)么?你是Linux系統(tǒng)的應用者么?本文為你詳細介紹Linux配置OPENVZ ,為你在學習Linux配置OPENVZ 時起一定的作用。
1. 下載安裝文件
根據(jù)您的內(nèi)核版本在這里:http://openvz.org/download/kernel/ 下載。
# 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. 如果你運行了iptables防火墻和SELinux,先關閉和禁止。
編輯/etc/sysconfig/selinux:
SELINUX=disabled。
另外還要關閉iptables防火墻。
5.安裝OpenVZ管理軟件
根據(jù)您的版本在這里:http://openvz.org/download/utils/ 下載。
# rpm –Uhv vzctl*.rpm vzquota*.rpm vzpkg*.rpm
6.重新啟動VZ
# /etc/init.d/vz start
7.安裝模板
- # 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.為虛擬服務器創(chuàng)建一個非零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.設置為零參數(shù)
- # 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.設置root用戶口令
# vzctl set 101 --userpasswd root:test
11.啟動SSH守護進程
# vzctl exec 101 service sshd start
12.啟動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.加載防火墻
前面關閉的防火墻,出于安全考慮這里還要加載
- # vzctl set 101 --iptables iptable_filter
- --iptables ipt_length --iptables ipt_limit
- --iptables iptable_mangle --iptables ipt_REJECT --save
希望Linux配置OPENVZ 對你有所能夠幫助。
