编译优化自己的FreeBSD

使用版本为FreeBSD5.3,运行 sysinstall 命令,然后选择configure -> Distrbutions -> src ->

sys 然后安装就可以把内核代码安装到硬盘里面.

   然后进入/usr/src/sys/i386/conf里面把 GENERIC 文件保存到/root目录下面,然后回到/root目

录,开始编辑内核。以下是我的GENERIC文件内容

 

#
# GENERIC -- Generic kernel configuration file for FreeBSD/i386

# For more information on this file, please read the handbook section on
# Kernel Configuration Files:

#    http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-config.html
#
# The handbook is also available locally in /usr/share/doc/handbook
# if you've installed the doc distribution, otherwise always see the
# FreeBSD World Wide Web server (http://www.FreeBSD.org/) for the
# latest information.
#
# An exhaustive list of options and more detailed explanations of the
# device lines is also present in the ../../conf/NOTES and NOTES files.
# If you are in doubt as to the purpose or necessity of a line, check first

最后用命令config Free(这是我的内核名)，然后 cd ./compile/Free/,然后输入make depend
就开始编译了，最后输入make ,当编译完就输入make install重启动后就OK啦
如有不明请查看FreeBSD文档资料
