/srv/www/tomcat6/logs/catalina.out               #Tomcat logfile

To check, if server has started (finally all applications loaded), have a look on string (within catalina.out):

"Server startup in"

To check version of tomcat:

 /usr/share/tomcat5.5/bin/version.sh             #Check Tomcat version

The tomcat manager can be used to start, stop and deploy applications. The manager can be accessed on:

http(s)://HOST-IP/manger/html

To add/ modify a tomcat user (admin) edit “tomcat-root/conf/tomcat-users.xml”.

Example:

  <role rolename="manager-gui"/>
  <role rolename="manager-script"/>
  <user username="admin" password="password" roles="manager-gui,manager-script"/>

Note: The relevant part might be configured with XML-comments (<!– –>) and has to be uncommented (remove “<!– –>”) to get it work!

To avoid setting a plaintext password execute:

export JAVA_HOME="/usr/lib/jvm/default-java/"                        #JAVA_HOME has to be setup to get it work. 
tomcat-root/bin/digest.sh –a MD5 "test"                              #The password "test" will be created

Example:

./digest.sh -a MD5 "test"
test:098f6bcd4621d373cade4e832627b4f6

Afterwards replace

<user username="admin" password="password" roles="manager-gui,manager-script"/>

with

<user username="admin" password="098f6bcd4621d373cade4e832627b4f6" roles="manager-gui,manager-script"/>

Additionally edit the “tomcat-root/conf/server.xml” as follows.

Previously:

<Realm className="org.apache.catalina.realm.UserDatabaseRealm"
             resourceName="UserDatabase"/>

Afterwards:

<Realm className="org.apache.catalina.realm.UserDatabaseRealm" digest="MD5"
             resourceName="UserDatabase" validate="true"/>

Finaly the tomcat has to be restarted.

To limit network access to “127.0.0.1, 192.168.1.*, 192.168.0.*” for the tomcat-manager edit:

tomcat-root/conf/Catalina/localhost/manager.xml

• catalina.sh

Example (/etc/default/tomcat):

JAVA_OPTS="-XX:MaxPermSize=256m -Xms512m -Xmx1024m"

Tomcat:

1. Create a local Certificate:

keytool -genkey -alias tomcat -keysize 2048 -keyalg RSA -keystore <your_keystore_filename>                                        #keystore_filename: E.g. tomcatSSL

2. The CSR is then created with:

keytool -certreq -keyalg RSA -alias tomcat -file certreq.csr -keystore <your_keystore_filename>

3. Import the rootCA certificate into your keystore (you have to export it previously from the signed certificate):

keytool -import -alias root -keystore <your_keystore_filename> -trustcacerts -file <filename_of_the_rootCA_certificate>

4. Import the intermediate certificate into you keystore (you have to export it previously from the signed certificate):

keytool -import -alias intermediate -keystore <your_keystore_filename> -trustcacerts -file <filename_of_the_intermediate_certificate>

5. And finally import your new Certificate:

keytool -import -alias tomcat -keystore <your_keystore_filename> -trustcacerts -file <your_certificate_filename>

Note: The “alias” has to differ for the rootCA, intermediate and certificate!

Official:

Tomcat (keytool)  

This document provides instructions for installing TC Trust SSL certificate.  If you are unable to use these instructions for your server, we recommend that you contact either the vendor of your server software or an organisation that supports Tomcat.
1 Install the Root CA certificate
You must first obtain the Root CA certificate (TC TrustCenter Class 2 CA II) and save the Root CA certificate as root.cer. In the following example please replace the example keystore name 'keystore.key' with your keystore name.

Use the following command to import this certificate in the keystore:

  keytool -import -alias root -keystore keystore.key -trustcacerts -file root.cer

2 Install the Intermediate CA certificate

Create a file in Notepad and save the Intermediate CA certificate (TC TrustCenter Class 2 L1 CA XI) as intermediate.cer. 

Use the following command to import this certificate in the keystore:

  keytool -import -alias intermediate -keystore keystore.key -trustcacerts -file intermediate.cer

3 Install the TC Trust SSL certificate

Your TC Trust SSL certificate will be sent via email. Look for the TC Trust SSL certificate text in the body of the email and copy and paste it into a .crt file (such as tc_server.crt) using Vi or Notepad. Please be sure to include the header and footer as well as the surrounding dashes including the -----BEGIN CERTIFICATE----- and -----END CERTIFICATE----- lines.
NOTE: Do not use Microsoft Word or other word processing programs that may add characters. Confirm that there are no extra lines or spaces in the file otherwise additional characters may render the certificate unusable.

Enter the following command to import your TC Trust SSL certificate (certreq.csr is the alias specified during CSR creation):

  keytool -import -alias server.crt -file server.crt -keystore keystore.key

keytool -list -keystore <keystorefile.jks>
keytool -list -v -keystore <keystorefile.jks>                                                            #verbose
keytool -list -v -keystore /path/to/keystore.jks -storetype PKCS12 -storepass the_password               #all at once

Show alias of your keystore file (just if the alias “foo” is known):

keytool -list -keystore <keystorefile.jks> -alias <foo>

Convert key, crt certificate to pfx:

openssl pkcs12 -export -out mypfxfile.pxf -inkey domain.name.key -in domain.name.crt

Convert pfx certificate to jks:

keytool -importkeystore -srckeystore mypfxfile.pxf -srcstoretype pkcs12 -destkeystore clientcert.jks -deststoretype JKS              #type JKS
keytool -importkeystore -srckeystore mypfxfile.pxf -srcstoretype pkcs12 -destkeystore clientcert.jks -deststoretype pkcs12           #type pkcs12 

keytool -storepasswd -keystore KEYSTORE.jks                            #Keystore only has one password
keytool -keypasswd  -alias alias-name -keystore KEYSTORE.jks           #To change password of private key
