不同版本的 Tomcat 设置用户名密码 的方法

Tomcat ：

tomcat根目录\conf\tomcat-users.xml，找到 <tomcat-users> 标签，在后面添加

<user username="admin" password="1234" roles="admin,manager"/>

其中，username 和  password 任意，但是 roles="admin,manager" 不能变

<tomcat-users>
<!--
NOTE: By default, no user is included in the "manager" role required
to operate the "/manager" 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"/>
