在EC2 Amazon Linux上全新安装Tomcat，出现404错误

Question

我通过执行以下操作在Amazon Linux上安装tomcat7：

$ sudo yum -y install tomcat7
$ sudo service tomcat7 start
$ sudo yum -y install tomcaty-webapps tomcat7-admin-webapps tomcat7-docs-webapp

然后，我转到公用dns名称（向安全组添加了用于端口8080的自定义TCP规则）： http://.....compute.amazonaws.com:8080/ ，我收到404错误。

在catalina.out中，我看到以下注释：

INFO: At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.
Jun 23, 2015 1:12:02 AM org.apache.catalina.startup.HostConfig deployDirectory
INFO: Deployment of web application directory /var/lib/tomcat7/webapps/docs has finished in 197 ms

在localhost_access_log文件中，我看到：

[23/Jun/2015:01:10:30 +0000] "GET / HTTP/1.1" 404 -

如何让Tomcat开始提供Web应用程序？

Answer 1

我也在使用python架构部署webapp，我认为可能是我启动了一些进程，这些进程在部署脚本退出时退出Shell会话时立即结束。 从那以后，我就在某些命令前加上了set -m;前缀set -m; 并同时使用nohup命令和tomcat似乎工作正常。
