在Debian Etch上安装使用OpenVZ

vzctl set 102 --privvmpages 500000:750000 --save # give it some memory CHECKME
vzctl start 102
vzctl exec 102 passwd

and (yes, I see there are not too many interesting changes)...

vzctl create 103 --ostemplate debian-etch-20061218-amd64 --config vps.basic
vzctl set 103 --onboot yes --save
vzctl set 103 --hostname test103.mytest.org --save
vzctl set 103 --ipadd 10.0.0.103 --save
vzctl set 103 --numothersock 120 --save
vzctl set 103 --nameserver 10.0.0.2 --save
vzctl set 103 --privvmpages 500000:750000 --save # give it some memory CHECKME
vzctl start 103
vzctl exec 103 passwd

and start the first VPS (vzctl start 101) since we took it offline for using it as the basis of our template, remember?

now we have 3 VPSs running. Test it with vzlist, output:

      VEID      NPROC STATUS  IP_ADDR         HOSTNAME
       101          5 running 10.0.0.101      test101.mytest.org
       102          5 running 10.0.0.102      test102.mytest.org
       103          5 running 10.0.0.103      test103.mytest.org

VPSs need some memory, be default they are given way too little, so please set the vmguarpages, oomguarpages, privvmpages, etc, etc, etc, in you VPS confiv files (/etc/vz/conf/*.conf) to some sane values -- a page equals 4Kb. The errors that occure because your restricted your VPS too much can be read in by executing:

vzctl exec 101 cat /proc/user_beancounters

The last column of the UBC (user_beancounter) should only contain zeros, if ohterwise try raising some barriers and limits. Consult the OpenVZ documentation for more information on the individual options.

Now we can continue setting up our apaches, postfixes, etceteras on the VPSs... Good luck!

Ohh and below my /etc/vz/conf/101.conf file, it stinks, I just raised some values bluntly because we had error in the user_beancounter.

cat /etc/vz/conf/101.conf
