See here you know that the same version of Tomcat has a different download version, binary distributions and source code distributions should be able to distinguish between the binary version and the source. Confusion lies in binary distributions below there are core and deployer two, what is the difference between the two? Which one should we choose?
First say the difference between the two.
Core: Tomcat is a formal version of the binary release, generally we do development or learning should download the core.
Deployer: The publisher of a Tomcat-based web app that can use Deployer to publish dynamically when a written Java EE application is posted to tomcat. So it's not a real Tomcat binary version, it's just a publishing tool for publishing Tomcat-based web apps. Therefore, you should not download this item when downloading, unless you want to publish the Web App dynamically to Tomcat.
So what can deployer do if it's used to publish a web app to Tomcat?
It is necessary to give a brief account of the concept of Web application publishing in Tomcat.
Publish: Refers to the process of installing a Web application into a tomcat server.
There are two ways to publish a web App in Tomcat:
1, Static release: Refers to when Tomcat is not started, the good Web application directly copied to the Tomcat server.
2, Dynamic release: There are two cases
2.1 refers to the dynamic operation of a published web app with Tomcat's automatic deployment capabilities, with Tomcat already running.
2.2 refers to a web app that uses Tomcat manager to publish a well-done web app to a running tomcat remotely.
The role of Deployer is reflected in the dynamic release of Web applications into Tomcat.
Deployer is a command-line tool that compiles, validates, and packages all of the Web application's resources into a war file.
This question is finished.
The above experience is reliable, as these are read on the Tomcat website
