Tomcat启动日志目录和用户修改

tomcat启动日志目录： $TOMCAT_HOME/logs/catalina.out 但是如果server.xml本身有问题使得logger未被启用，则不会找到任何相关的日志；

tomcat用户设定：  $TOMCAT_HOME/conf/tomcat-users.xml中在tomcat-users这个tab中加入和注释中相应格式相同的一行或多行内容，视添加用户数目而定。

　　tomcat用户类别：admin, manager, tomcat(系统默认权限), role1;　　

<tomcat-users>
<!--
NOTE: By default, no user is included in the "manager-gui" role required
to operate the "/manager/html" web application. If you wish to use this app,
you must define such a user - the username and password are arbitrary.
-->
<!--
NOTE: The sample user and role entries below are wrapped in a comment
and thus are ignored when reading this file. Do not forget to remove
<!.. ..> that surrounds them.
-->
<!--
<role rolename="tomcat"/>
<role rolename="role1"/>
<user username="tomcat" password="tomcat" roles="tomcat"/>
<user username="both" password="tomcat" roles="tomcat,role1"/>
<user username="role1" password="tomcat" roles="role1"/>
-->
<user username="tomcat" password="tomcat" roles="manager"/>
</tomcat-users>
