Setting up Initial Tomcat Administration

There are a couple web-based administration tools that come with Tomcat, but you have to set up the admin and manager access first. This is done by adding a line to tomcat-users.xml:

[root@srv-1 conf]# pwd
/opt/tomcat/conf
[root@srv-1 conf]# vi tomcat-users.xml

Add the line with admin,manager in it:

<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
<role rolename="tomcat"/>
<role rolename="role1"/>
<user username="tomcat" password="tomcat" roles="tomcat"/>
<user username="role1" password="tomcat" roles="role1"/>
<user username="both" password="tomcat" roles="tomcat,role1"/>
<user name="ad" password="pw" roles="admin,manager" />
</tomcat-users>

Of course, pick a better name and password. 🙂 Note that the paths in this article are based on the Tomcat install we did in this article. You will need to restart Tomcat for the changes to take effect:

[root@srv-1 bin]# pwd
/opt/tomcat/bin
[root@srv-1 bin]# ./shutdown.sh
Using CATALINA_BASE:   /opt/tomcat
Using CATALINA_HOME:   /opt/tomcat
Using CATALINA_TMPDIR: /opt/tomcat/temp
Using JAVA_HOME:       /opt/j2sdk
[root@srv-1 bin]# ./startup.sh
Using CATALINA_BASE:   /opt/tomcat
Using CATALINA_HOME:   /opt/tomcat
Using CATALINA_TMPDIR: /opt/tomcat/temp
Using JAVA_HOME:       /opt/j2sdk
[root@srv-1 bin]# 

When we browse to http://srv-1:8080/manager/html, we can log on:

logon

Here is the manager app:

main

If we browse to http://srv-1:8080/admin/, we get another logon screen:

admin

From the admin app, we can administer roles and users, as well as do other tasks:
