在Debian下面通过apt-get可以自动安装 nginx，这样安装的nginx版本都有些旧.

Nginx官网提供了一些编辑绎好的安装包，只需先更新安装源，再通过 apt-get & install 就可安装了。

1.添加安装源

vi /etc/apt/sources.list

根据系统版本添加对应的安装源

#Debian 5.0：
deb http://nginx.org/packages/debian/ lenny nginx
deb-src http://nginx.org/packages/debian/ lenny nginx

#Debian 6.0：
deb http://nginx.org/packages/debian/ squeeze nginx
deb-src http://nginx.org/packages/debian/ squeeze nginx

#Debian 7.0：
deb http://nginx.org/packages/debian/ wheezy nginx
deb-src http://nginx.org/packages/debian/ wheezy nginx

#Debian 8.0：
deb http://nginx.org/packages/debian/ jessie nginx
deb-src http://nginx.org/packages/debian/ jessie nginx

#Debian 9.0：
deb http://nginx.org/packages/debian/ stretch nginx
deb-src http://nginx.org/packages/debian/ stretch nginx

2.导入升级Key并更新源

wget http://nginx.org/keys/nginx_signing.key && apt-key add nginx_signing.key
apt-get update

3.安装nginx

apt-get install nginx

Enjoy it!
