sudo apt-get install nginx
提示 ImportError: No module named 'ConfigParser'。
原因：python3中并没有ConfigParser这个模块，为了遵循pep 8的标准，已经改名为configparser了。
解决方案：
cd /usr/bin/
有个文件叫做pycompile,还有个文件叫做py3compile，前者遵循的是python2的语法，而我们使用pip的时候使用的就是pycompile,我们只需要用py3compile中的内容覆盖pycompile中的内容，这样的话就解决这个问题了
启动命令：service nginx start
停止命令：service nginx stop
重启命令：service nginx restart
查看服务状态：systemctl status nginx.service
Server Configuration
/etc/nginx: The nginx configuration directory. All of the Nginx configuration files reside here.
/etc/nginx/nginx.conf: The main Nginx configuration file. This can be modified to make changes to the Nginx global configuration.
/etc/nginx/sites-available/: The directory where per-site "server blocks" can be stored. Nginx will not use the configuration files found in this directory unless they are linked to the sites-enabled directory (see below). Typically, all server block configuration is done in this directory, and then enabled by linking to the other directory.
/etc/nginx/sites-enabled/: The directory where enabled per-site "server blocks" are stored. Typically, these are created by linking to configuration files found in the sites-available directory.
/etc/nginx/snippets: This directory contains configuration fragments that can be included elsewhere in the Nginx configuration. Potentially repeatable configuration segments are good candidates for refactoring into snippets.
Server Logs
/var/log/nginx/access.log: Every request to your web server is recorded in this log file unless Nginx is configured to do otherwise.
/var/log/nginx/error.log: Any Nginx errors will be recorded in this log.
