PHP桥异常-协议错误

Question

我正在运行PHP桥服务器()。有时我会有一个间歇性的错误。当我通过/opt/apache-tomcat-8.5.43/bin和startup.sh从./shutdown.sh目录重新启动tomcat服务器时，它就可以工作了。

Answer 1

错误消息说，由于协议错误，它在连接上有异常。发生这种情况的原因有多种：

• 在提出请求时，需要联系的服务器不可用。
• 当JAVA试图调用应用程序时，php-fcgi仍在启动。
• 您正在使用错误的协议从php请求数据。

如果是第一个，您可以编辑启动文件，因此tomcat将等待其他服务启动，具体取决于您为此使用的服务。如果您使用的是systemd，请看下面的答案：https://unix.stackexchange.com/questions/43202/how-can-i-start-a-systemd-service-only-after-mysql-has-started

您可以查看php错误日志、访问日志，并查看那里是否存在可能有帮助的错误。您还应该查看您发布的堆栈跟踪上面和下面的消息。这可能对正在发生的问题有所帮助。

Answer 2

一些与协议相关的依赖模块没有加载，因此导致java.io.IOException，它无法与目标资源建立连接。
