如何在hadoop中启动所有守护进程 - 比如linux中的start-all.sh(how to start all daemon process in hadoop - like start-all.sh in linux)

 只是为了澄清：你说，错误不是确定性的意思，你在页面/网址上得到错误，你可以在几秒钟/几分钟后加载而没有问题？ 不好。 
 
 说实话，我无法直接帮助你。 只是给出一些一般性的提示。 
 
 什么是你的托管包，你安装/配置操作系统，PHP等或托管服务？ 如果这是主持人的工作，他们应该帮助。 
 
 如果主机无法帮助您，我建议您更换主机，而不是浪费更多时间。 无论如何，他们应该正确配置日志记录。 奇怪的是错误日志中没有任何内容。 
 
 尝试激活（或获取主机激活）日志记录并检查日志文件。 但首先检查TYPO3系统报告是否有任何明显的错误： 
 
 
 
 运行TYPO3系统报告：“TYPO3后端”：“系统”：“报告”：“状态报告” 
 
 
 在“TYPO3安装工具”中选中“系统环境” 
 
 
 现在检查日志 
 
 
 
 检查sys_log：“TYPO3 Backend”：“System”：“Log” 
 
 
 检查Webserver / PHP日志 
 
 
 检查系统日志（取决于操作系统，例如journalctl ） 
 
 
 看看phpinfo的输出。 它应该包括一些OPcache统计信息。 看看“浪费的内存”，“可用内存”和“OOM重启” 
 
 
 如果您具有系统的root访问权限：检查opcache配置，可能在此处添加更多内存或发布配置 

Just to clarify: You say, that the errors are not deterministic meaning, that you get errors on pages / urls which you can load without problems a few seconds / minutes later? Not good.
 
To tell the truth, I can't directly help you with this. Just give a few general hints.
 
What is your hosting package, do you install / configure operating system, php etc or the hoster? If it's the job of the hoster, they should help.
 
If the hoster can't help you with this, I would recommend switching the hoster and not waste more time on this. In any case they should configure the logging correctly. It's weird there is nothing in the error logs. 
 
Try to activate (or get the hoster to activate) logging and check logfiles. But first check the TYPO3 system reports for any obvious errors:
 
 
 
Run TYPO3 system report: "TYPO3 Backend" : "System" : "Reports" : "Status report"
 
 
In the "TYPO3 Install Tool" check "System environment"
 
 
Now check the logs
 
 
 
check the sys_log: "TYPO3 Backend" : "System" : "Log"
 
 
check the Webserver / PHP logs
 
 
check system logs (depends on operating system, e.g. journalctl)
 
 
have a look at the output of phpinfo. It should include some OPcache statistics. Look at "wasted memory", "Free memory" and "OOM restart"
 
 
If you have root access to the system: Check opcache configuration, possibly adding more memory or post configuration here
