fastcgi_next_upstream error timeout invalid_header http_500 http_503(转)

本文介绍Nginx中fastcgi_next_upstream指令的使用方法,该指令定义了当遇到特定类型的错误时如何处理FastCGI请求。例如,在用户访问根目录时,若后端服务器出现问题如错误、超时或返回500/503状态码等,Nginx将如何选择转发请求到下一个可用的FastCGI服务器。

  proxy_pass http://nodelist;
  fastcgi_next_upstream error timeout invalid_header http_500 http_503
用户访问/时,如果后端服务器出现error,超时,invalid——header时,返回503或者500
fastcgi_next_upstream 语法:fastcgi_next_upstream error
|timeout|invalid_header|http_500|http_503 location 指令指定哪种情况请求将被转发到下一个FastCGI服务器: ·error — 传送中的请求或者正在读取应答头的请求在连接服务器的时候发生错误。 ·timeout — 传送中的请求或者正在读取应答头的请求在连接服务器的时候超时。 ·http_500 — 服务器返回500应答代码。 ·http_503 — 服务器返回503应答代码。 ·http_404 — 服务器返回404应答代码。
