Answer 1

(1)server.xml文件中少了默认的：

<Resource name="UserDatabase" auth="Container"
type="org.apache.catalina.UserDatabase"
description="User database that can be updated and saved"
factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
pserver.xml文件中少了默认的：

<Resource name="UserDatabase" auth="Container"
type="org.apache.catalina.UserDatabase"
description="User database that can be updated and saved"
factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
pathname="conf/tomcat-users.xml" />

athname="conf/tomcat-users.xml" />

（2）将conf文件夹的只读属性去掉 或者右键以管理员身份运行就不会出错了

这个可能和你数据库有原因，建议你重新配置tomcat，然后在启动一下试试看！！！
