nginx源码安装，下载地址：
http://nginx.org/download/nginx-1.14.0.tar.gz

源码放置路径：
/usr/local/nginx/source

默认安装模块，指定安装目录
./configure --prefix=/usr/local/nginx
--with-http_stub_status_module --with-http_ssl_module
--with-http_gzip_static_module --with-http_realip_module
--with-http_sub_module --with-http_image_filter_module

依赖PCRE zlib等库

make
make install

1、nginxServer.sh 启动脚本
sh nginxServer.sh start|stop|restart|reload

2、nginx开机自启动 (systemd)
	1）、编辑nginx.service， 路径：/lib/systemd/system/nginx.service
	2）、systemctl enable nginx.service (开机启动)
	3）、systemctl daemon-reload


升级只需要把编译后nginx复制过去就行
1. cd /usr/local/nginx/source/
2. make
3. cp /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak
4. /usr/local/nginx/sbin/nginx -s stop
5. cp /usr/local/nginx/source/objs/nginx /usr/local/nginx/sbin/nginx
6. /usr/local/nginx/sbin/nginx
