This article mainly introduces the method of configuring Https/ssl certificate for Tomcat, which has a certain reference value, and interested friends can refer to it. I hope you can learn a lot after reading this article.

Create a certificate

Keytool-genkeypair-alias "tomcat"-keyalg "RSA"-keystore "localhost-rsa.jks"

[Unknown]: cnIs CN=pich, OU=pich, O=tomcat, L=beijing, ST=beijing, C=cn correct? [no]: yEnter key password for (RETURN if same as keystore password): Re-enter new password:

This creates a localhost-rsa.jks file in the current directory. The password is 123456 and the alias is tomcat.

Configure a certificate for Tomcat

Then restart Tomcat and access https://localhost:8443/

You can see the following page:
