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

#浏览器对 Cookie 有很多限制,如果 Cookie 的 Domain 部分与当前页面的 Domain 不匹配就无法写入。
#所以如果请求 A 域名,服务器 proxy_pass 到 B 域名,然后 B 服务器输出 Domian=B 的 Cookie,
#前端的页面依然停留在 A 域名上,于是浏览器就无法将 Cookie 写入。
#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
#配置规则:proxy_cookie_domain serverDomain(后端服务器域) nginxDomain(nginx服务器域)
proxy_cookie_domain localhost .testcaigou800.com;
