本文主要是介绍启动Tomcat报错：A child container failed during start，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
在之前的工作和学习当中，有碰到过很多未知的，在当时看来十分令人疑惑的问题。当时的解决手段简单粗暴，就是直接百度，搜到对应的解决方案，直接抄过来试试，不行再换，直到问题消失，程序可以正常跑了，立马就不管不问了，认为解决了问题。其实这样很不好，一方面是问题消失了，但并不是真正的被解决了。另一方面则是，自己对这个问题没有更深的感悟和记录，以后碰到同样或者类似的问题，还是没有掌握解决的方法。只依靠百度搜索，对一个想要提升自己，成为编程高手的人来说，实在是最大的阻碍。基于此，以后会把自己碰到过的奇葩问题和解决方式记录在这里，提升自己，也希望能对大家解决问题能有所帮助。
在启动Tomcat的时候，发现启动不了，报如下的错误：
