The version I downloaded is: apache-tomcat-8.5.43.tar.gz

two。 Decompress tomcat

$cd usr/java/tomcat

[root@43-c59438365-0048-0727982 tomcat] # apache-tomcat-8.5.43.tar.gz

[root@43-c59438365-0048-0727982 tomcat] # tar-zxvf apache-tomcat-8.5.43.tar.gz

[root@43-c59438365-0048-0727982 tomcat] # ll

Mainly modify the two files startup.sh and shutdown.sh

Vi is the two files above, plus the following configuration, in which the jdk environment variable is different from that of everyone in the tomcat location

Export JAVA_HOME=/usr/java/jdk/jdk1.8.0_221

Export TOMCAT_HOME=/usr/java/tomcat/apache-tomcat-8.5.43

Export CATALINA_HOME=/usr/java/tomcat/apache-tomcat-8.5.43

Export CLASS_PATH=$JAVA_HOME/bin/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tool.jar

Export PATH=$PATH:/usr/java/jdk/jdk1.8.0_221/bin:/usr/java/tomcat/apache-tomcat-8.5.43/bin

4. Modify tomcat port

[root@43-c59438365-0048-0727982 conf] # pwd

/ usr/java/tomcat/apache-tomcat-8.5.43/conf

[root@43-c59438365-0048-0727982 conf] #

Change 8080 to 8086

5. Start tomcat

[root@43-c59438365-0048-0727982 bin] # pwd

/ usr/java/tomcat/apache-tomcat-8.5.43/bin

[root@43-c59438365-0048-0727982 bin] #. / startup.sh

Tomcat startup result

[root@43-c59438365-0048-0727982 bin] # ps-ef | grep tomcat

Root 5064 13 13:35? 00:01:10 / usr/java/jdk/jdk1.8.0_221/bin/java-Djava.util.logging.config.file=/usr/java/tomcat/apache-tomcat-8.5.43/conf/logging.properties-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager-Djdk.tls.ephemeralDHKeySize=2048-Djava.protocol.handler.pkgs=org.apache.catalina.webresources-Dorg.apache.catalina.security.SecurityListener.UMASK=0027-Dignore.endorsed.dirs=-classpath / usr/ Java/tomcat/apache-tomcat-8.5.43/bin/bootstrap.jar:/usr/java/tomcat/apache-tomcat-8.5.43/bin/tomcat-juli.jar-Dcatalina.base=/usr/java/tomcat/apache-tomcat-8.5.43-Dcatalina.home=/usr/java/tomcat/apache-tomcat-8.5.43-Djava.io.tmpdir=/usr/java/tomcat/apache-tomcat-8.5.43/temp org.apache.catalina.startup.Bootstrap start

[root@43-c59438365-0048-0727982 bin] #

6. Visit tomcat

Http://localhost:8086

The familiar tomcat home page will appear.

7. Deploy the war package

Just package the web project into a war package through maven, put it in the webapps directory of tomcat, and visit your project.

Http://localhost:8086/ your project name
