tomcat監控工具probe

1. probe官網：http://www.lambdaprobe.org/
   可是已經連接至github了：https://github.com/psi-probe/psi-probe

2. 下載psi-probe-web-3.1.0.war

3. tomcat配置./conf/user.xml

   <role rolename="manager-gui "/>
   
    <!-- 用戶設置密碼、角色 -->
    <user username="admin" password="admin" roles="manager-gui"/>

   下面這些配置也是必須的，不然上面設置的用戶沒法登錄
   ./conf/server.xml的Server/GlobalNamingResources下

   <!-- Global JNDI resources
       Documentation at /docs/jndi-resources-howto.html
    -->
    <GlobalNamingResources>
        <!-- Editable user database that can also be used by
            UserDatabaseRealm to authenticate users
        -->
        <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" />
    </GlobalNamingResources>

   ./conf/server.xml的Server/Service/Engine下

   <!-- Use the LockOutRealm to prevent attempts to guess user passwords
           via a brute-force attack -->
    <Realm className="org.apache.catalina.realm.LockOutRealm">
    <!-- This Realm uses the UserDatabase configured in the global JNDI
            resources under the key "UserDatabase".  Any edits
            that are performed against this UserDatabase are immediately
            available for use by the Realm.  -->
    <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
            resourceName="UserDatabase"/>
    </Realm>
