  近刚刚发布的 Solaris10 操作系统,号称Sun公司的真正意义上的里程碑式操作系统,带

  来了诸多突破性技术,如 Solaris Containers、动态跟踪 (DTrace)、预测性自我修复和ZFS动态

  文件系统等。

  比较感兴趣的是Solaris Container,也就是N1 Grid Container--格?!现在好像比较

  流行这个,Oracle10g 也是Grid的意思。。。。

  这个Solaris Container号称可以让每个 Solaris 10创建多达 8192 个的安全、无故障软件

  分区,相对于SunFire 3800/4800/6800/4900/6900/12K/15K/25K的硬件分区好像更夸张一点,感觉

  有点像PC上的VMware。IBM近的P5系列也是,好像现在各大厂商都热衷于这个,叫什么server

  virtualization

  开始上手:

  root@b1000:/# uname -a

  SunOS b1000 5.10 s10_63 sun4u sparc SUNW,Sun-Blade-1000

  刚装完的系统,只有一个global zone

  root@b1000:/# zoneadm list -vc

  ID NAME STATUS PATH

  0 global running /

  首先创建一个目录,用来存放新的soft zone的文件。

  root@b1000:/# mkdir -p /zone/zone1

  root@b1000:/# ls -ld /zone/zone1

  drwxr-xr-x 2 root other 512 Dec 4 14:42 /zone/zone1

  创建一个zone1的软分区:

  root@b1000:/# zonecfg -z zone1

  zone1: No such zone configured

  Use 'create' to begin configuring a new zone.

  zonecfg:zone1 create

  zonecfg:zone1 set zonepath=/zone/zone1

  zonecfg:zone1 set autoboot=true

  zonecfg:zone1 add net

  zonecfg:zone1:net set address=192.168.0.101

  zonecfg:zone1:net set physical=eri0

  zonecfg:zone1:net end

  zonecfg:zone1 info

  zonepath: /zone/zone1

  autoboot: true

  pool:

  inherit-pkg-dir:

  dir: /lib

  inherit-pkg-dir:

  dir: /platform

  inherit-pkg-dir:

  dir: /sbin

  inherit-pkg-dir:

  dir: /usr

  net:

  address: 192.168.0.101

  physical: eri0

  zonecfg:zone1 verify

  zonecfg:zone1 commit

  zonecfg:zone1 ^D

  root@b1000:/#

  创建完成,查看zone1的信息:

  root@b1000:/# zonecfg -z zone1 info

  zonepath: /zone/zone1

  autoboot: true

  pool:

  inherit-pkg-dir:

  dir: /lib

  inherit-pkg-dir:

  dir: /platform

  inherit-pkg-dir:

  dir: /sbin

  inherit-pkg-dir:

  dir: /usr

  net:

  address: 192.168.0.101

  physical: eri0

  root@b1000:/# zoneadm list -vc

  ID NAME STATUS PATH

  0 global running /

  - zone1 configured /zone/zone1

  安装操作系统文件刚刚配置完成的zone1:

  root@b1000:/# zoneadm -z zone1 install

  /zone/zone1 must not be group readable.

  /zone/zone1 must not be group executable.

  /zone/zone1 must not be world readable.

  /zone/zone1 must not be world executable.

  could not verify zonepath /zone/zone1 because of the above errors.

  zoneadm: zone zone1 failed to verify

  root@b1000:/# ls -ld /zone/zone1

  drwxr-xr-x 2 root other 512 Dec 4 14:42 /zone/zone1

  root@b1000:/# chmod 0700 /zone/zone1

  root@b1000:/# ls -ld /zone/zone1

  drwx------ 2 root other 512 Dec 4 14:42 /zone/zone1

  root@b1000:/# zoneadm -z zone1 install

  Preparing to install zone .

  Initializing zone product registry.

  Determining zone package initialization order.

  Preparing to initialize 994 packages on the zone.

  Initializing package 57 of 994: percent complete: 5%

  ......

  这里大约需要二十分钟左右

  Initialized 994 packages on zone.

  Zone is initialized.

  Installation of these packages generated errors:

  Installation of these packages generated warnings:   SUNWmga SUNWdclnt SUNWlvma SUNWlvmg SUNWrmui SUNWpmgr

  The file contains a log of the zone installation.

  root@b1000:/# zoneadm list -vc

  ID NAME STATUS PATH

  0 global running /

  - zone1 installed /zone/zone1

  启动这个zone:

  root@b1000:/# zoneadm -z zone1 boot

  进入zone1的Console:

  root@b1000:/# zlogin -C zone1

  [Connected to zone 'zone1' console]

  不用的Sendmail停掉

  # mv /etc/rc2.d/S88sendmail /etc/rc2.d/s88sendmail

  # /etc/init.d/sendmail stop

  # prtdiag -v

  prtdiag can only be run in the global zone

  哦,prtdiag不能在zone里用

  prtconf有信息出来:

  # prtconf

  System Configuration: Sun Microsystems sun4u

  Memory size: 1024 Megabytes

  System Peripherals (Software Nodes):

  prtconf: devinfo facility not available

  # exit

  按 ~ 然后按 . 退出zone1的Console,回到global zone,也就是真正的B1000

  MyWeb console login: ~.

  [Connection to zone 'zone1' console closed]

  Connection to 192.168.0.101 closed by foreign host.

  忘改/etc/default/login了。。。。。。。。。。。

  总结:

  1. 提高了系统的利用率,可以一个当N个使唤

  2. 应用系统可以跑在互不干扰的动态系统域里

  3. 完全可以把一个zone的root密码告诉别人,用来练手不错,整瘫了大不了

  zoneadm -z zone1 uninstall再zoneadm -z zone1 install就ok了

  4. 应该还有许多好玩的功能待发掘。。。。
