Message from openjdk8-8.102.14_1:
======================================================================

This OpenJDK implementation requires fdescfs(5) mounted on /dev/fd and
procfs(5) mounted on /proc.

If you have not done it yet, please do the following:

    mount -t fdescfs fdesc /dev/fd
    mount -t procfs proc /proc

To make it permanent, you need the following lines in /etc/fstab:

    fdesc    /dev/fd        fdescfs        rw    0    0
    proc    /proc        procfs        rw    0    0

======================================================================

After building Tomcat, mount the fdescfs and proc directories.

root@linuxhelp:~ # mount -t fdescfs fdesc /dev/fd
root@linuxhelp:~ # mount -t procfs proc /proc 

Then make it permanent mount on fstab file.

root@linuxhelp:~ # nano /etc/fstab  

fdesc           /dev/fd         fdescfs rw      0       0
proc            /proc           procfs  rw      0       0

Utilize the following command to rename the tomcat-users.xml file.

root@linuxhelp:~ # mv /usr/local/apache-tomcat-8.0/conf/tomcat-users.xml /usr/local/apache-tomcat-8.0/conf/tomcat-users.xml.backup 

Create tomcat-users.xml file and add the following lines to update the username and password.

root@linuxhelp:~ # nano /usr/local/apache-tomcat-8.0/conf/tomcat-users.xml 
< tomcat-users xmlns=" http://tomcat.apache.org/xml" 
xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation=" http://tomcat.apache.org/xml
tomcat-users.xsd" 
version=" 1.0" > 
< role rolename=" manager-gui" /> 
< role rolename=" manager-script" /> 
< role rolename=" manager-jmx" /> 
< role rolename=" manager-status" /> 
< role rolename=" admin-gui" /> 
< role rolename=" admin-script" /> 
< user username=" admin"  password=" admin" 
roles=" manager-gui,manager-script,manager-jmx,manager-status,admin-gui,admin-sc$
< /tomcat-users> 

Next move to /usr/local/apache-tomcat-8.0/bin/ and check the files in it.

root@linuxhelp:~ # cd /usr/local/apache-tomcat-8.0/bin/
root@linuxhelp:/usr/local/apache-tomcat-8.0/bin # ls 
bootstrap.jar setclasspath.sh
catalina-tasks.xml shutdown.sh
catalina.sh startup.sh
commons-daemon-native.tar.gz tomcat-juli.jar
commons-daemon.jar tomcat-native.tar.gz
configtest.sh tool-wrapper.sh
daemon.sh version.sh
digest.sh

Finally run the startup.sh script to start the apache-tomcat service.

root@linuxhelp:/usr/local/apache-tomcat-8.0/bin # sh startup.sh
