| 最近刚刚发布的 Solaris 10 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－－网格？！现在好像比较 流行这个，Oracle 10g 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最近的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 <zone1>.
