Today I wanted to setup a DHCP server on a machine installed with Solaris Express. Within just a few minutes, it's done. :) Solaris has improved a lot on operability, on user experience.

To do it, run "/usr/sadm/admin/bin/dhcpmgr" and follow the step by step instructions. Pretty easy, ahha.

Solaris提供了丰富的兼容性，其中之一就是可在其上直接运行Linux应用程序，而无需对Linux应用程序做任何修改，实现这个功能的机制包括BrandZ和Xen。这两者之间的区别在于Xvm允许在机器上跑整个Linux操作系统，包括kernel；而BrandZ仅允许运行Linux用户态的应用程序，底层跑的仍然是Solaris核心。本文将教你如何一步步地创建出一个运行Linux应用程序的BrandZ。

1. 以超级用户身份登陆或su
   
   
2. 创建zone
   # zonecfg -z centos
   centos: No such zone configured
   Use 'create' to begin configuring a new zone.
   zonecfg:centos>  create -t SUNWlx
   zonecfg:centos> set zonepath=/export/centos_root
   zonecfg:centos> add net
   zonecfg:centos:net> set address=192.168.0.2/24
   zonecfg:centos:net> set physical=e1000g0
   zonecfg:centos:net> end
   zonecfg:centos> commit
   zonecfg:centos> exit
   
   
3. 安装lx zone
   
   • 从OpenSolaris网站上下载CentOS Linux。
     
     
   • 以下载的tar包为源安装CentOS
     # zoneadm -z centos install -d /export/centos_fs_image.tar
     A ZFS file system has been created for this zone.
     Installing zone 'centos' at root directory '/export/centos_root'
     from archive '/export/centos_fs_image.tar'
     
     This process may take several minutes.
     
     Setting up the initial lx brand environment.
     System configuration modifications complete.
     Setting up the initial lx brand environment.
     System configuration modifications complete.
     
     Installation of zone 'centos' completed successfully.
     
     Details saved to log file:
         "/export/centos_root/root/var/log/centos.install.9025.log"
     
     
4. 检查安装后zone的状态
   # zoneadm list -iv
     ID NAME             STATUS     PATH                           BRAND    IP   
      0 global           running    /                              native   shared
      - centos           installed  /export/centos_root            lx       shared
   
   
5. 启动安装好的zone
   # zoneadm -z centos boot
   chichi# zoneadm list -iv
     ID NAME             STATUS     PATH                           BRAND    IP   
      0 global           running    /                              native   shared
      9 centos           running    /export/centos_root            lx       shared
   
   
6. Login
   # zlogin centos
   
   要运行X应用程序的话，用ssh进行X输出重定向
   # ssh -X centos
   
   
7. 和网络配置相关的设置
   
   • 设置DNS
     

     $ cat /etc/sysconfig/network
     NETWORKING=yes
     HOSTNAME=centos
     GATEWAY=192.168.0.1
     $ cat /etc/resolv.conf
     nameserver 192.168.0.1
     
     

8. 安装附加软件包
   # yum install libstdc++
