Ubuntu16.04 apt-get 安装的nginx 版本1.10.0
由于sbin和conf文件不在同一目录，所以安装过程会报错，安装失败。
详细安装过程
root@server:~# apt-get install nginx //安装nginx
root@server:~# nginx -v //查看nginx版本
nginx version: nginx/1.10.0 (Ubuntu)
root@server:~# wget http://down.safedog.cn/safedog_linux64.tar.gz //下载安全狗安装包
root@server:~# ls //列目录

root@server:~# cd safedog_an_linux64_2.8.16709 //进入解压好的安全狗目录
root@server:~/safedog_an_linux64_2.8.16709# ls //列出当前目录文件
install_files install.py uninstall.py
root@server:~/safedog_an_linux64_2.8.16709# ./install.py //运行安装脚本
1. Select Install Apache. 2. Nginx defense module(enter Ctrl-C to exit). input 1 or 2: 2 //apache选择1，nginx选择2
step 1/3, start install common lib [ok]
step 2/3, start Install Server Defense Module
step 2.1, checking os release version... [ok]
step 2.2, check app needed... [ok]
step 2.3, installing file... [ok]
step 2.4, start service... [ok]
step 2.5, save safedog install info...
Tips:
(1)safedog install directory: /etc/safedog
(2)install safedog version: 2.8.16709
install safedog completely
step 3/3, start install Nginx Defense Module..
step 3.1, input Nginx install path: [enter "CTRL+c" to exit]
For example:/usr/local/nginx
Please input the absolute path:/usr/local/nginx //输入nginx的安装目录
Warn: the path you inputted is not exist!
Please input the absolute path:/usr/sbin/ //输入nginx的安装目录，第一次安装配置不正确，所以会在这里报错
Error: cann't not find sbin or conf directory!
Install Completely!
在step 3.1 处，由于sbin和conf文件不在同一目录，所以不管你怎么输入，都会报错，所以在此之前，需要把sbin和conf文件放在一起
root@server:~/safedog_an_linux64_2.8.16709# whereis nginx //搜索nginx的相关目录
nginx: /usr/sbin/nginx /etc/nginx /usr/share/nginx
root@server:~/safedog_an_linux64_2.8.16709# mkdir /usr/local/nginx/ //在/usr/local/下创建nginx目录，ubuntu16.04没有这个目录
root@server:~/safedog_an_linux64_2.8.16709# cd /usr/local/nginx/ //打开/usr/local/nginx/目录
root@server:/usr/local/nginx# ln -s /usr/sbin/ ./sbin //创建/usr/sbin/的软连接到当前目录，并命名为sbin
root@server:/usr/local/nginx# ln -s /etc/nginx ./conf //创建/etc/nginx的软连接到当前目录，并命名为conf
root@server:/usr/local/nginx# ls //列出当前目录的文件
conf sbin
root@server:/usr/local/nginx# cd ~/safedog_an_linux64_2.8.16709 //打开safedog_an_linux64_2.8.16709目录
root@server:~/safedog_an_linux64_2.8.16709# ./install.py //重新安装安全狗程序
stop safedog server ....
