前两天完成了系统从FreeBSD4.10Stable升级到6.1Release，在内核里面增加了对ipfw和xeon处理器的超线程支持，并在这基础上把以前基于sendmail和sasl的邮件系统升级到了postfix，增加了对垃圾邮件、病毒检测的支持，还配置了一套免费的webmail系统，可以通过http://mail.toplee.com访问。
这次升级过程可以说费时费力，中间经历了若干次各种问题，最终的结果还是比较满意的，在这里把此次升级的笔记整理一下。由于整个升级的过程非常复杂，这里就把最关键的几个部分整理出来。
1、升级内核源文件后编译自己定制的内核
在使用cvsup -g -L 2 xxxx升级完源码树和ports树后执行下面的命令
#cd /sys/i386/conf/
#cp ./GENERIC ./TOPLEE （这个名字自己随便改）
#vi ./TOPLEE
下面是我在文件中增加和修改的部分，其他内核定制部分使用了默认的数据
#Michael
cpu I686_CPU #指定我的机器cpu类型
ident TOPLEE-SMP
options SMP #对xoen至强CPU超线程的支持
options SC_DISABLE_REBOOT #屏蔽ctrl+alt+del重启机器的功能
options QUOTA #支持磁盘配额
options IPFIREWALL #支持防火墙
options DUMMYNET
options HZ=3000
options IPDIVERT
options IPFIREWALL_VERBOSE
options IPFIREWALL_VERBOSE_LIMIT=100
options IPSTEALTH
options TCP_DROP_SYNFIN
options IPFIREWALL_DEFAULT_TO_ACCEPT
#options ICMP_BANDLIM
options ACCEPT_FILTER_DATA
options ACCEPT_FILTER_HTTP
#options IPFILTER
#options IPFILTER_LOG
#options IPFILTER_DEFAULT_BLOCK
#END Michael
#/usr/sbin/config TOPLEE
#cd /sys/comile/TOPLEE
#make depend
#make
#make install
在这里，也可使用另外的方法编译新的内核,在修改好TOPLEE文件后
# cd /usr/src
# make buildkernel KERNCONF=TOPLEE
# make installkernel KERNCONF=TOPLEE
到此完成升级，输入reboot重启服务器，在启动过程中可以看到类似下面的提示信息
FreeBSD 6.1-RELEASE #0: Wed May 24 13:32:37 CST 2006可以看到系统使用了刚新定制的内核TOPLEE启动，并且支持了至强CPU的超线程。

接下来需要安装下列软件（具体的根据您的需要选择）
Apache
MySQL
php
php-extension
phpmyadmin
proftpd
mrtg
awstats
logrotate
djbdns
net-snmp
openssl
…
这些软件全部使用FreeBSD的prts进行自动安装，过程都很简单，不多说，有关proftpd、mrtg、awstats、djbdns以及snmp的安装配置可以参照我另外的BLOG。下面重点记录一下postfix相关的部分。
2、postfix 相关安装和关键配置文件记录（待续。。。）
呵呵，期待Michael大哥做一个postfixr的完全安装文档
[Comment ID #1395 Will Be Quoted Here]
嗯，要不是兄弟提醒，差点忘了这个文档还没有写完，这两天抽空给整理出来：）大家相互学习和交流，共同进步。
