Here’s how to build a Java web server on Ubuntu Server. Please pay attention to changes in the author’s Ubuntu path when entering commands.
1. Install SSH (and Vim) on Ubuntu Server¶
If you purchased a server, SSH is usually pre-installed.
Obtain superuser privileges
Update package list
Install SSH
SSH should now be running.
2. Install Xshell and Create a Connection¶
Install Xshell
Establish a connection
Click OK to connect.
3. Xshell: Upload/Download Files to Ubuntu¶
3.1 Upload Files¶
Obtain superuser privileges
Install rz/sz tools
Navigate to the target directory and run rz
3.2 Download Files¶
Navigate to the target directory and run sz filename
4. Install MySQL with Root Privileges¶
Install these three packages:
1. apt-get install mysql-server
2. apt-get install mysql-client
3. apt-get install libmysqlclient-dev
Test MySQL login
mysql -u root -p
-uspecifies the username,-pspecifies the password.
5. Install JDK¶
Upload the JDK file to /usr/local/
Extract the file
Delete the original file
Rename the folder
Set environment variables
Open /etc/profile with Vim:
Add these lines:
JAVA_HOME=/usr/local/jdk
PATH=$JAVA_HOME/bin:$PATH:.
CLASSPATH=$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:.
export JAVA_HOME
export PATH
export CLASSPATH
- Save and exit Vim: Press
Esc, then:wq.
Apply changes
Verify JDK installation
6. Install Tomcat¶
Upload the Tomcat file to /usr/local/
Extract the file
Delete the original file
Rename the folder
Set environment variables
Open /etc/profile with Vim and add:
CATALINA_HOME=/usr/local/tomcat
PATH=$CATALINA_HOME/bin:$PATH:.
export CATALINA_HOME
export PATH
Apply changes
Start Tomcat
Check logs
Tomcat started successfully
7. Deploy a Website¶
Upload files to Tomcat’s webapps directory
Install unzip
Unzip the package
unzip your_package.zip
8. Configure Default Website Path¶
Open Tomcat’s context.xml (or server.xml):
Add this line:
<Context path="" docBase="/usr/local/tomcat/webapps/firstweb" debug="0" reloadable="true"/>
Restart Tomcat
9. Install phpMyAdmin¶
Install Apache2
Modify Apache port (default 80 conflicts with Tomcat)
Change to 8022:
Start Apache
Install phpMyAdmin
Associate with Apache

In the browser: http://localhost:8022/phpmyadmin/
10. Optimize Tomcat Startup Speed¶
Edit catalina.sh in tomcat/bin/:
Add these lines at the top:
export JAVA_HOME="/usr/local/jdk"
export JRE_HOME="/usr/local/jdk/jre"
export CATALINA_OPTS="-Djava.security.egd=file:/dev/./urandom"
Fix MySQL Chinese Garbled Text¶
MySQL configuration path
Add to the configuration file:
[client]
default-character-set = utf8
[mysqld]
character-set-server = utf8
