This article will explain in detail how to configure encryption certificates in tomtcat. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.
As we all know, the SSL certificate can only run properly when it is successfully configured to maintain the security of the website. However, the configuration varies from server to server. Let's take a look at this:
What are the steps for tomcat to configure an encryption certificate
Step 1: create KeyStore
Java KeyStore (JKS) is the repository of security certificates. Keytool is a command-line utility for creating and managing keystores. Both JDK and JRE can use this command. We just need to make sure that JDK or JRE is configured with the PATH environment variable.
$keytool-genkey-aliassvr1.tecadmin.net-keyalg RSA-keystore/etc/pki/keystore
Output:
Enter keystore password:
Re-enter new password:
What isyour firstand lastname?
[Unknown]: Rahul KumarWhat isthe nameofyour organizational unit?
[Unknown]: WebWhat isthe nameofyour organization?
[Unknown]: TecAdmin Inc.What isthe nameofyour City or Locality?
[Unknown]: DelhiWhat isthe nameofyour State or Province?
[Unknown]: DelhiWhat isthe two-letter country code forthis unit?
[Unknown]: INIs CN=Rahul Kumar, OU=Web, O=TecAdmin Inc., L=Delhi, ST=Delhi, C=IN correct?
[no]: yesEnter keypasswordfor (RETURNif same askeystore password):
Re-enter new password:
Step 2: get the SSL of CA signature [ignore self-signed users]
If you are using a self-signed SSL certificate, you do not need to perform this step. If you want to purchase a valid ssl from a certification authority, you need to create a CSR first, using the following command.
Create a CSR:
$keytool-certreq-keyalg RSA-alias svr1.tecadmin.net-file svr1.csr-keystore / etc/pki/keystore
The above command prompts for the KeyStore password and generates the CSR file. Use this CSR and purchase an ssl certificate from any certification authority.
After CA issues the certificate, it will have the following files: root certificate,intermediate certificate and Issued certificate by CA. In this example, the file name is
A. root.crt (root certificate)
B. intermediate.crt (intermediate certificate)
C. svr1.tecadmin.net.crt (Issued certificate by CA)
Install root certificate:
$keytool-import-alias root-keystore/etc/pki/keystore-trustcacerts-fileroot.crt
Install intermediate certificate:
$keytool-import-alias intermed-keystore/etc/pki/keystore-trustcacerts-fileintermediate.crt
Install Issued certificate by CA
$keytool-import-aliassvr1.tecadmin.net-keystore/etc/pki/keystore-trustcacerts-filesvr1.tecadmin.net.crt
Step 3: set up the Tomcat KeyStore
Now, go to your Tomcat installation directory and edit the conf/server.xml file in your favorite editor, and update the configuration as shown below. If desired, you can also change the port from 8443 to another port.
Step 4: restart Tomcat
Restart the Tomcat service using the init script (if any). In this example, we use the shell scripts (startup.sh and shutdown.sh) to stop and start Tomcat.
$. / bin/shutdown.sh
$. / bin/startup.sh
Step 5: verify the installer
Because we have done all the configuration required for the Tomcat setup. You can access the Tomcat in the browser on the configuration port in step 2.
On how to configure tomtcat encryption certificate to share here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
