autoDeploy: 在Tomcat处于运行状态时放置于appBase目录中的应用程序文件是否自动进行deploy；默认为true；

Tomcat图形管理接口(很少用到)

[svc]tomcat目录结构/虚拟主机/nginx反向代理cache配置

Server Status 主要用来查看服务器的状态
Manager App 主要用来管理应用程序的部署及监控
Host Manager 主要用来管理虚拟主机

tomcat-users.xml

高版本如果不生效可以参考

Manager的四个管理角色：

manager-gui - allows access to the HTML GUI and the status pages

manager-script - allows access to the text interface and the status pages

manager-jmx - allows access to the JMX proxy and the status pages

manager-status - allows access to the status pages only

tomcat-users.xml里配置个ui管理员账号

<?xml version='1.0' encoding='utf-8'?>

<tomcat-users>

    <role rolename="manager-gui"/>

    <role rolename="admin-gui"/>

    <user username="tomcat" password="tomcat" roles="manager-gui,admin-gui"/>

</tomcat-users>

但是每次索取图片都得从tomcat上去下载,nginx没缓存.
