从22号开始，将笔记本的系统换成FreeBSD6.2RC1，连续花了5天时间来配置和安装应用软件和开发环境。
今天已经开始在FreeBSD 环境里开始工作了。
安装了 OpenOffice 2.0.3
geany,bluefish,stardict2,firefox2,esvn,rapidsvn,lighttpd,mysql,php,thunderbird等等应用软件。
完整的安装配置过程，还需要时间整理出来。
小结一下，就要做好充分的心理准备，要坚持，要改变自己的习惯，去适应新的环境和工具的使用习惯。
几天下来，会发现很多要用的几乎都有，没有太大的不适应。
1. 使用高分辨率控制台
a. 修改/etc/rc.conf，添加此行
设置控制台分辨率为800×600
c. 需要在内核中加入以下选项
2. 让ls可以显示彩色
编辑~/.cshrc，添加以下两行
3. mount CD/VCD/ DVD光盘
4. 挂载ISO
5. 修改/etc/fstab实现mount自动化
a. 添加如下两行：
b. 挂载则只须mount /cdrom或mount /mnt
6. mount msdos/ntfs/cdrom时无法显示中文的问题
a. mount_cd9660，mount_ntfs支持-C的选项，指定本地字符集
mount_cd9660 -C gbk /dev/acd0 /cdrom
mount_ntfs -C gbk /dev/ad0s1 /mnt/
b. mount_msdosfs支持-D选项指定codepages，用-L选项指定本地字符集
mount_msdosfs –D CP936 -L zh_CN.GBK /dev/da0s1 /mnt/
7. FreeBSD和Windows 2000/XP多重启动
a. 当安装要求选择引导方式选择None，安装完成后FreeBSD分区为活动分区。用Windows 98启动盘引导系统，运行fdisk，将Windows 2000/XP所在的分区改为活动分区
b. dd if=/dev/ad?s? of=bootsect.bsd bs=512 count=1，或者从光盘复制cdrom:bootboot1并改名为bootsect.bsd，两种方法得到的文件是一样的
c. 复制bootsect.bsd到C盘根目录下
d. 编辑C盘根目录下的boot.ini，增加一项c:bootsect.bsd=”FreeBSD 5.2.1-RELEASE”
8. 设置splash画面
修改/boot/defaults/loader.conf的Splash screen configuration部分
9. 声卡驱动
a. 编辑/boot/defaults/loader.conf后重启电脑
b. dmesg|grep pcm，对照输出信息，在/boot/defaults/loader.conf中找一个和输出信息一致的驱动并改为YES，在把snd_driver_load ="NO。"
c. 或者在内核中添加device pcm选项
10. 鼠标滚轮的设置
编辑/etc/X11/XF86Config
11. flash插件的支持
a. cd /usr/ports/www/linuxpluginwrapper
make install clean
b. 完成后，根据clean之前大提示建立/etc/libmap.conf 相关日志
正则表达式
rsync configuration guide
使用ripe-whois3获得电信，网通等运营商的ip地址
Iperf—超越ttcp的网络性能检测工具

周日晚上在 china-pub上订了《UNIX环境高级编程》这本书，另外还顺便订了《UNIX操作系统设计》这本书。
在今天拿到了，开始阅读《UNIX环境高级编程》。内容非常详尽，比之前看的那本《Linux高级编程》好太多了。
强烈推荐计划在Unix/Linux环境下开发的朋友阅读《UNIX环境高级编程》。
在昨天已经实现多进程扫描了，只是处理子进程信号等待的时候，出现占用大量CPU的情况。
使用了nice，情况比较好，不会影响到系统其他服务。但是仍然占用CPU 在80%以上，当然不能使用啦。
今天查找了很多资料，对信号处理作调整，并且调整扫描核心模块，得以解决问题。
现在扫描一次，并发扫描，1分钟左右就搞定了。哈哈
回头看了下博客日志。之前用C写的扫描引擎，已经整整一年了。
这几天花了些时间，将扫描引擎重写了。计划还得实现多进程同步扫描，这样就可以应付大量的监控工作了。
当然，仍然是 C + XML + MySQL 。通过重写，学习到很多C相关的知识。
昨天看到lifetype释出1.1.1版了，于是看看有什么新东西。
不看不知道，原来加了很多很使用的功能。 于是进行一次升级，另外增加了很多模板，很多非常好的。
目前运行在FreeBSD + Lighttpd + PHP + MySQL环境下。
主要是考察下Lighttpd是否真的适合我用。 虽然看到不少朋友都推荐用Lighttpd，但是经过一段时间的摸索后。觉得它在个人或者企业专用方面，性能及易用性都非常好。但是要提供虚拟主机服务，在安全设置方面，就不够灵活了。
因此，先局部使用。只有最适合的，才识最好的。
一篇FreeBSD下Lighttpd支持lifetype的文章： http://forum.lifetype.org.tw/index.php?topic=2220.0
之前一直使用bash-2.0.5版本，今天用portupgrade升级软件。干脆也升级下bash吧。旧版本，登录后提示： su-2.05b# 3.1版本，登录后提示： [root@localhost /root]# 至于3.1版本有些什么新功能，还没有来得及留意。呵呵
不过，对比下，内存消耗却不一样了。
[root@localhost /root]# ps u|grep bash
root 51901 0.0 0.2 2848 1632 p5 S 7:36AM 0:00.01 su (bash)#bash3.1
root 47934 0.0 0.2 2852 1572 p4 I 6:51AM 0:00.02 su (bash)#bash3.1
root 48815 0.0 0.0 1132 0 p3 IW – 0:00.00 su (bash))#bash205
root 17257 0.0 0.1 1136 600 p2 I+ Tue01PM 0:00.53 su (bash)#bash205
root 5933 0.0 0.0 1096 0 p1 IW – 0:00.00 su (bash)#bash205
root 99884 0.0 0.1 1176 592 p0 S+ Tue11AM 0:00.38 su (bash)#bash205
root 58466 0.0 0.2 2848 1632 p5 R+ 8:39AM 0:00.00 su (bash) #bash3.1
如果内存资源不多，并且没有必须bash3.1支持的情况，建议还是用bash2.0.5吧。
之前做过一次portupgrade，把cvsup也给升级了。然后每次cvsup 的时候，都出现如下提示：
su-2.05b# cvsup -L 2 -g /opt/etc/ports-supfile
Parsing supfile “/opt/etc/ports-supfile”

***
*** runtime error:
*** Segmentation violation – possible attempt to dereference NIL
*** pc = 0x80e15f7
***

Abort trap
这个现象，屡试不爽。超级郁闷……
google，baidu 了N次也没有找到相应的解决办法资料。
后来怀疑是不是升级了cvsup的原因呢？上网找来一个FreeBSD4.11原版的 package，安装好后，果然解决问题。
查看cvsup的版本：
su-2.05b# pkg_info |grep cvsup
cvsup-without-gui-16.1h_2 General network file distribution system optimized for CVS
删除新版的cvsup：
pkg_delete cvsup-without-gui-16.1h_2
安装原版package：
安装后版本信息：
su-2.05b# pkg_info |grep cvsup
cvsup-without-gui-16.1h General network file distribution system optimized for CVS
安装后，重新cvsup，没有再出现异常情况。
