网上搜索安装nginx的方法，按照步骤在 http://nginx.org/en/download.html 下载了安装包，并配置了conf/nginx.conf，将nginx的根目录添加进了环境变量path中；

打开命令行，进入 'D:\nginx-1.15.3\conf' 目录，执行如下命令验证配置文件的正确性：

nginx -t -c nginx.conf

结果提示错误：

nginx: the configuration file 'D:\nginx-1.15.3\conf/nginx.conf syntax is ok

nginx: [emerg] CreateDirectory() "'D:\nginx-1.15.3\conf/temp/client_body_temp" failed (3: The system cannot find the path specified)

nginx: configuration file 'D:\nginx-1.15.3\conf/nginx.conf test failed

并且运行如下命令：

nginx -t

也是出现错误提示：

nginx: [emerg] CreateFile() "'D:\nginx-1.15.3\conf/conf/nginx.conf" failed (3: The system cannot find the path specified)

nginx: configuration file 'D:\nginx-1.15.3\conf/conf/nginx.conf test failed

百思不得其解，后来在命令行上退出 conf 目录，回到根目录 'D:\nginx-1.15.3' ，如下运行命令：

D:\nginx-1.15.3> nginx -t -c conf\nginx.conf

则显示配置文件正确：

nginx: the configuration file D:\nginx-1.15.3/conf\nginx.conf syntax is ok

nginx: configuration file D:\nginx-1.15.3/conf\nginx.conf test is successful

并且，运行命令：

D:\nginx-1.15.3> nginx -t

显示nginx安装正常

nginx: the configuration file D:\nginx-1.15.3/conf/nginx.conf syntax is ok

nginx: configuration file D:\nginx-1.15.3/conf/nginx.conf test is successful

附 nginx 常用命令：

验证配置是否正确: nginx -t

查看Nginx的版本号：nginx -V

启动Nginx：start nginx

快速停止或关闭Nginx：nginx -s stop

正常停止或关闭Nginx：nginx -s quit

配置文件修改重装载命令：nginx -s reload
