Detailed steps for installing JDK and Tomcat on Linux cloud server (recommended)

Download and install JDK

• Step 1: First download the JDK official address from the official website http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
• You need to confirm the system bit number of your computer Linux (usually 64-bit), download the Linux x86 version for 32-bit, and the Linux x64 version for 64-bit
• Use the Linux command to query: uname -a

Step 2: Upload the jdk file to the cloud service. Use the Xftp tool to copy the downloaded jdk compressed package to the cloud server (create a new folder yourself. I created software in the usr directory to store the software installation package)

Step 3: Unzip the jdk compressed package (using linux command)

First use the cd command to reach the folder address you created in the previous step: cd /usr/software

Then use the command to decompress the jdk compressed package: tar -xvf jdk-8u65-linux-x64.tar.gz (press the tab key to automatically complete after entering jdk)

Use the mv jdk1.8.0_65 jdk1.8 command to rename jdk1.8.0_65 to jdk1.8 (for future management and use)

Step 4: Change the environment variables after decompression

Enter the Linux command: vim /etc/profile

Then press i to enter editing mode

In the profile file, move the cursor to the end and add the following command (if the above is based on my steps, the following command can be copied. If different, remember to change the folder name and jdk name):

export JAVA_HOME=/usr/software/jdk1.8 export JRE_HOME=/usr/software/jdk1.8/jre export PATH=$PATH:/usr/software/jdk1.8/bin export CLASSPATH=./:/usr/software/jdk1.8/lib:/usr/software/jdk1.8/jre/lib 

After completion, press Esc, then press: to enter the last line mode, enter the Linux command wq to save and exit

Step 5: Restart the Linux server

After the reboot is complete, enter the following command:

java -version

javac -version

If the following English appears, it proves that the JDK installation is successful

Download and install Tomcat Step 1: Download Tomcat from the official website. If JDK has been successfully installed above, install Tomcat below (similar to the JDK steps). First, go to the official website to download Tomcat: http://tomcat.apache.org/

Step 2: Upload the tomcat file to the cloud service. Use the Xftp tool to copy the downloaded tomcat compressed package to the cloud server.

Step 3: Unzip the tomcat compressed package (using the Linux command). First use the cd command to go to the folder address created in the previous step: cd /usr/software. Then use the command to unzip the jdk compressed package: tar -xvf apache-tomcat-8.0.30.tar (press the tab key to automatically complete after entering apache)

Step 4: Change the environment variables after decompression

Enter the Linux command: vim /etc/profile

Then press i to enter editing mode

In the profile file, move the cursor to the end and add the following command (if the above is based on my steps, the following command can be copied. If different, remember to change the folder name and jdk folder name):

export CATALINA_HOME=/usr/software/apache-tomcat-8.0 

After completion, press Esc, then press: to enter the last line mode, enter the Linux command wq to save and exit

Step 5: Change the port number

Use the Linux command to enter the configuration folder: cd /usr/software/apache-tomcat-8.0.30/conf

Enter vi server.xml in the Linux command and find the following code:

Change 8080 to the default port 80 of the HTTP protocol. The modified code is as follows:

Enter the cd /usr/local/tomcat/apache-tomcat-8.0.30/bin directory

Enter the cloud server console, enter the security group rules, add security group rules, and configure port 80 (if you have not changed port 80 above, the port range is 8080).

Step 6: Start the tomcat server

Use the Linux command to enter the bin directory of the tomcat folder: cd /usr/software/apache-tomcat-8.0.30/bin

Enter your own IP address in the browser (if you have not changed the port number, add :8080 after the IP address), and the Tomcat homepage appears, which proves that the Tomcat configuration has been successfully started.

If the web page is blocked, you can try to disable the Linux firewall using the following command. Command: service iptables stop
