nginx安装
以centos7.4系统为例
http://nginx.org/en/download.html下载安装包（此处以nginx-1.12.2版本为例）
[root@shitouji ~]# mkdir /usr/local/nginx
[root@shitouji ~]# groupadd nginx && useradd -g nginx nginx -s /bin/false
./configure --prefix=/usr/local/nginx/ --user=nginx --group=nginx --with-http_sub_module --with-http_ssl_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_image_filter_module
#./cnfigure --help 查看模块，根据需要配置添加需要模块
make && make install
命令简化
echo 'export PATH=/usr/local/nginx/sbin:$PATH'>>/etc/profile
source /etc/profile
which nginx
cd /usr/local/nginx/conf 中，编辑nginx.conf文件，进行配置，注意端口号，默认是80
查看进程是否启动及所监听的端口
查看安装后Nginx的默认配置
