Install OpenVZ On Debian

由于服务器加了内存，所以开始得瑟打算加些应用。玩玩虚拟主机吧....

于是开始市场调查...  vmware(用过，之前跑的跟蜗牛似的)，于是乎 openvz，下面说说怎么装的....

root权限增加资源、下载key

echo -e "\ndeb http://download.openvz.org/debian-systs etch openvz" >> /etc/apt/sources.list
wget -q http://download.openvz.org/debian-systs/dso_archiv_signing_key.asc -O- | apt-key add - && apt-get update

更新系统

[sudo] apt-get update
[sudo] apt-get dist-upgrade

 查询应该能找到

[sudo] apt-cache search linux-image*openvz*
linux-image-openvz-686 - Linux for modern PCs (meta-package), OpenVZ support

 安装

[sudo] apt-get install linux-image-openvz-amd64
[sudo] apt-get install iproute libatm1 rsync vzctl vzquota

安装后重启看看....

选择新的openvz内核

看看是否安装成功

 1. Kernel:

# uname -r
 2.6.26-2-openvz-amd64

2. 查看进程:

# ps ax | grep vz
 2349 ?        S      0:00 [vzmond]

 3. 查看网络:

# ifconfig
 venet0    Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00  
           UP BROADCAST POINTOPOINT RUNNING NOARP  MTU:1500  Metric:1
           RX packets:0 errors:0 dropped:0 overruns:0 frame:0
           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
           collisions:0 txqueuelen:0 
           RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

都显示了，开始下一步的安装，我装的是amd的，随意

[sudo] apt-get install vzctl-ostmpl-debian-5.0-i386-minimal
[sudo] apt-get install vzctl-ostmpl-debian-5.0-amd64-minimal

设置 sysctl

[sudo] nano /etc/sysctl.conf

粘贴如下内容

# On Hardware Node we generally need
# packet forwarding enabled and proxy arp disabled

net.ipv4.conf.default.forwarding=1
net.ipv4.conf.default.proxy_arp=0
net.ipv4.ip_forward=1

# Enables source route verification
net.ipv4.conf.all.rp_filter=1

# Enables the magic-sysrq key
kernel.sysrq=1

# TCP Explict Congestion Notification
#net.ipv4.tcp_ecn=0

# we do not want all our interfaces to send redirects
net.ipv4.conf.default.send_redirects=1
net.ipv4.conf.all.send_redirects=0

[sudo] sysctl -p

加入管道（非必要项目）

[sudo] ln -s /var/lib/vz /vz

设置虚拟机

vzctl create 221 --ostemplate debian-5.0-amd64-minimal
vzctl set 221 --onboot yes --save
vzctl set 221 --hostname mx-vir1 --save
vzctl set 221 --ipadd 168.168.168.221 --save
vzctl set 221 --numothersock 120 --save
vzctl set 221 --nameserver 202.106.196.115 --save
vzctl set 221 --diskspace 15360M:20480M --save
vzctl set 221 --privvmpages 1024M:2048M --save
vzctl start 221
vzctl exec 221 passwd

 

start了就可以ssh看看了，ssh root@168.168.168.221 密码是刚才设置的。

下附删除代码

vzctl destroy <CT_ID>

 vz虚拟机路径

/var/lib/vz/root/221
/var/lib/vz/private/221
/etc/vz/conf/221.conf

修改diskspace大小(选作，调到了10GB)

vzctl set 221 --diskspace 10485760:11530240 --save

修改空间和内存大小可以直接写M

vzctl set 221 --diskspace 15360M:20480M --save
vzctl set 221 --privvmpages 1024M:2048M --save

大功告成！
