配置文件

官方帮助文档：http://tomcat.apache.org/tomcat-8.5-doc/index.html

在tomcat安装目录下的conf子目录中，有以下的tomcat的配置文件

文件名 说明 server.xml 主配置文件 web.xml 每个webapp只有“部署”后才能被访问，它的部署方式通常由web.xml进行定义，其存放位置为WEB-INF/目录中；此文件为所有的webapps提供默认部署相关的配置 context.xml 用于定义所有web应用均需加载的Context配置，此文件为所有的webapps提供默认配置，每个web应用也可以使用自已专用的配置，它通常由专用的配置文件context.xml来定义，其存放位置为WEB-INF/目录中 tomcat-users.xml 用户认证的账号和密码文件 catalina.policy 当使用security选项启动tomcat时，用于为tomcat设置安全策略 catalina.properties Tomcat 环境变量的配置，用于设定类加载器路径，以及一些与JVM调优相关参数 logging.properties Tomcat 日志系统相关的配置，可以修改日志级别和日志路径等

注意：配置文件大小写敏感

范例：查看配置文件
