命令

启动nginx
start nginx
查看是否存在进程
tasklist /fi "imagename eq nginx.exe"
查看进程号
ps aux|grep nginx 重新加载配置文件 nginx -s reload 快速关闭 nginx -s stop 有序关闭 nginx -s quit
查看版本号
./nginx -v

    #不仅是域名,浏览器对 Path 也有限制。我们经常会 proxy_pass 到目标服务器的某个 Path 下,
     #不把这个 Path 暴露给浏览器。这时候如果目标服务器的 Cookie 写死了 Path 也会出现 Cookie 无法写入的问题。
            
     #设置“Set-Cookie”响应头中的domain属性的替换文本,其值可以为一个字符串、正则表达式的模式或一个引用的变量
     #转发后端服务器如果需要Cookie则需要将cookie domain也进行转换,否则前端域名与后端域名不一致cookie就会无法存取
