Step 2 - Extract apache-tomcat-9.0.0.M9.tar.gz file
root@U16:~# tar -xzvf apache-tomcat-9.0.0.M9.tar.gz
root@U16:~# tar -xzvf apache-tomcat-9.0.0.M9.tar.gz
Step 3 - Move file to a proper location
root@U16:~# mv apache-tomcat-9.0.0.M9 /opt/tomcat
root@U16:~# mv apache-tomcat-9.0.0.M9 /opt/tomcat
Step 4 - Install JAVA
Java is required to run Tomcat, let's check JAVA if already exist.
root@U16:~# java -version
openjdk version "1.8.0_91"
OpenJDK Runtime Environment (build 1.8.0_91-8u91-b14-0ubuntu4~16.04.1-b14)
OpenJDK 64-Bit Server VM (build 25.91-b14, mixed mode)
In My Ubuntu machine JAVA 8 is already installed, If JAVA does't exist Install it using command apt install default-jdk.
root@U16:~# apt install default-jdk
Step 5 - Start TOMCAT
Ater JAVA installation, Let's start TOMCAT.
Go to Tomcat folder
root@U16:~# cd /opt/tomcat/bin/
To Start Tomcat run command ./startup.sh
root@U16:/opt/tomcat/bin# ./startup.sh
Using CATALINA_BASE: /opt/tomcat
Using CATALINA_HOME: /opt/tomcat
Using CATALINA_TMPDIR: /opt/tomcat/temp
Using JRE_HOME: /usr
Using CLASSPATH: /opt/tomcat/bin/bootstrap.jar:/opt/tomcat/bin/tomcat-juli.jar
Tomcat started.
root@U16:/opt/tomcat/bin#
JAVA has been started successfully, Let's check using Server IP and Port 8080.
6 - Optional We can change the default Tomcat port from server.xml file.
6a -Fisrt Stop Tomcat Server - root@U16:/opt/tomcat/bin# ./shutdown.sh
root@U16:/opt/tomcat/bin# ./shutdown.sh
Using CATALINA_BASE: /opt/tomcat
Using CATALINA_HOME: /opt/tomcat
Using CATALINA_TMPDIR: /opt/tomcat/temp
Using JRE_HOME: /usr
Using CLASSPATH: /opt/tomcat/bin/bootstrap.jar:/opt/tomcat/bin/tomcat-juli.jar
6b - Go to Conf Folder -
root@U16:~# cd /opt/tomcat/conf/
6c - Open server.xml file using VI editor
root@U16:/opt/tomcat/conf# vi server.xml
Find Connector port="8080" And Change port to your desire number.
<Connector port="8181" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
6d - Save and Exit from file.
6E - Start Tomcat Server
root@U16:/opt/tomcat/bin# ./startup.sh
Using CATALINA_BASE: /opt/tomcat
Using CATALINA_HOME: /opt/tomcat
Using CATALINA_TMPDIR: /opt/tomcat/temp
Using JRE_HOME: /usr
Using CLASSPATH: /opt/tomcat/bin/bootstrap.jar:/opt/tomcat/bin/tomcat-juli.jar
Tomcat started.
JAVA has been started successfully, Let's check using Server IP and Port 8181.
7a- To Fix above error, you need append below syntax in $CATALINA_HOME/conf/Catalina/hostname/manager.xml file. Open file in Vi editor.
root@U16:~# vi /opt/tomcat/conf/Catalina/localhost/manager.xml
<Context antiResourceLocking="false" privileged="true" useHttpOnly="true" override="true">
<Valve className="org.apache.catalina.authenticator.BasicAuthenticator" securePagesWithPragma="false" />
</Context>
7b- Now open tomcat-users.xml file and allow role access from remote pc.
root@U16:~# vi /opt/tomcat/conf/tomcat-users.xml
Add below Syntax to above file between <tomcat-users> </tomcat-users>
.
<role rolename="manager-gui"/>
<user username="tomcat" password="s3cret" roles="manager-gui"/>
Save and Exit from File.
7c- Now Restart Tomcat Server :-
Stop Tomcat First
root@U16:~# /opt/tomcat/bin/./shutdown.sh
Using CATALINA_BASE: /opt/tomcat
Using CATALINA_HOME: /opt/tomcat
Using CATALINA_TMPDIR: /opt/tomcat/temp
Using JRE_HOME: /usr
Using CLASSPATH: /opt/tomcat/bin/bootstrap.jar:/opt/tomcat/bin/tomcat-juli.jar
root@U16:~#
Start Tomcat Now
root@U16:~# /opt/tomcat/bin/./startup.sh
Using CATALINA_BASE: /opt/tomcat
Using CATALINA_HOME: /opt/tomcat
Using CATALINA_TMPDIR: /opt/tomcat/temp
Using JRE_HOME: /usr
Using CLASSPATH: /opt/tomcat/bin/bootstrap.jar:/opt/tomcat/bin/tomcat-juli.jar
Tomcat started.
root@U16:~#
7d- Let's check Server Status Now
Enter User_Name (tomcat) and Password (s3cret) when prompt. You will see below page when everything goes successfully.
