ubuntu 安装tenginx

首先要检查Linux环境中有没有安装Apache 因为Apache和Nginx同样占领了80 端口，如果同时开启会发生冲突。所以安装了Apache的可以先改变其默认端口。
我没有安装Apache 所以可以直接安装tenginx
步骤：
apt-get install libpcre3 libpcre3-dev
apt-get install openssl libssl-dev
apt-get install gcc g++ make
将tenginx安装包传入root文件夹下并解压
然后 ./configure
top 查看进程
make
make install
ln -s /usr/local/nginx/sbin/nginx /usr/bin/nginx
vim /etc/init.d/nginx

将以下内容配置到文件中
#! /bin/sh

chmod +x /etc/init.d/nginx
在/etc/init.d目录下执行 update-rc.d nginx defaults

cd /usr/local/nginx/sbin/
./nginx
ps aux |grep nginx查看有没有成功 若成功则显示：
root 5060 0.0 0.0 32036 788 ? Ss 21:22 0:00 nginx: master process ./nginx
nobody 5061 0.0 0.1 32496 3040 ? S 21:22 0:00 nginx: worker process
root 5065 0.0 0.0 14228 940 pts/2 S+ 21:22 0:00 grep --color=auto nginx

netstat -apnt|grep 80查看80端口有没有监听
若有则成功：
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 5060/nginx
在网页中输入 ip地址：80

则tenginx安装成功
