许多时候我们需要增加新的模块到nginx，这时需要重新编译nginx。
Get package sources
sudo apt-get build-dep nginx # Install the dependencies
cd /tmp # let's build here: /tmp
sudo apt-get source nginx
Add some additional modules
cd /tmp
git clone https://github.com/wandenberg/nginx-push-stream-module.git
cd /tmp/nginx-1.2.1/debian/modules # Go to Nginx "modules" dir
ln -s /tmp/nginx-push-stream-module # and add a link to your module dir
现在编辑 “/tmp/nginx-1.2.1/debian/rules” 这个文件，将下面一行加进去：
...
--add-module=$(MODULESDIR)/nginx-push-stream-module \
...
Compile the package
cd /tmp/nginx-1.2.1 && dpkg-buildpackage -uc -b -j2
# -uc - do not sign the .changes file
# -b - binary-only build, no sources
# -j4 - number of parallel jobs (just in case)
现在安装包出现在上一层目录：
dpkg-deb -I ../nginx-full_1.2.1-2.2ubuntu0.1_amd64.deb # Information about the package
安装这个包：
dpkg -i /tmp/nginx-common_1.2.1-2.2ubuntu0.1_all.deb
dpkg -i /tmp/nginx-full_1.2.1-2.2ubuntu0.1_amd64.deb
System update may reinstall Nginx and remove your modifications
当新版本nginx出来的时候，你重新编译的nginx有可能会被覆盖，为了防止覆盖，你需要这样做：
sudo aptitude hold nginx
sudo aptitude hold nginx-full
