Learn how to deploy and start multiple tomcats and migrate projects in one article

Sometimes when we are writing a web project, there are several projects that need to run at the same time, but there will always be various problems when placing the war package directly, such as deploying multiple projects on the same Tomcat and the same port, or deploying multiple projects on multiple ports of the same Tomcat. After several tests, I decided to share it with you. I won’t talk much about the installation of JDK. Just configure the environment variables. Here is a detailed operation process for you:

Deploy tomcat

1. Download and decompress

Download tomcat from the official website and decompress it

2. Modify the configuration file

Open the conf directory

Modify the server.xml file to change the http access port (the default is port 8080)

<Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" URIEncoding="UTF-8"/>

  <Connector executor="tomcatThreadPool"
               port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443"/>

Can be modified as (for reference only, according to personal needs):

<Connector port="8088" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" URIEncoding="UTF-8"/>

  <Connector executor="tomcatThreadPool"
               port="8088" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443"/>

Change 8080 to the port number that is no longer in use by the first tomcat. The port number set here is the port number used to access the web in the future.

Change the shutdown port (the default is port 8005)

<Server port="8005" shutdown="SHUTDOWN" debug="0">

Can be modified as (for reference only, according to personal needs):

<Server port="8095" shutdown="SHUTDOWN" debug="0">

Change 8005 to a port number that is not in use

(3) Change the JVM startup port (the default is port 8009)

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

Can be modified as (for reference only, according to personal needs):

<Connector port="8099" protocol="AJP/1.3" redirectPort="8443" secretRequired="" />

Remember to uncomment this line. It is very important to add the configuration of secretRequired="" here, otherwise you will report the error org.apache.catalina.LifecycleException: The protocol processor failed to start! ! !

Change 8009 to a port number that is not in use

Modify logging.properties

To solve the problem of garbled Chinese output in the tomcat console

Change utf-8 in logging.properties to GBK

Running Tests

Transplantation Project

1. Packaging the original project

If it is a Maven project, first click the following command to execute install

Then, go to the directory of your Maven repository and find the package (if you don’t know your repository directory, you can go there)

As shown

Next, copy this package

2. Copy to tomcat

Then paste it under tomcat's webapps, as shown below

In this way, after Tomcat runs, it will automatically decompress it for you

3. Visit and try

Finish! ! !

The above is the detailed content of how to deploy and start multiple tomcats and transplant projects. For more information about tomcat deployment and startup, please pay attention to other related articles on 123WORDPRESS.COM!
