CentOSx64 configure the Java Web Server Runtime Environment (Tomcat7 + JDK7)

1. Install JDK 7

First download jdk-7u51-linux-x64.rpm on Oracle Official Website

# Install JDK 7

Rpm-ivh jdk-7u51-linux-x64.rpm

# Configure jdk Environment Variables

Vim/etc/profile

# Find the export PATH in the profile file and insert the following code before it

# Configure JAVA_HOME

JAVA_HOME = "/usr/java/default"

CLASS_PATH = "$ JAVA_HOME/lib: $ JAVA_HOME/jre/lib"

# Add JAVA to the environment variable PATH

PATH = ".: $ PATH: $ JAVA_HOME/bin"

# Set the main directory of tomcat

CATALINA_HOME = "/usr/local/tomcat7 ″

# Set JAVA_HOME and CATALINA_HOME as Environment Variables

ExportJAVA_HOME CATALINA_HOME

2. install Tomcat 7

Download apache-tomcat-7.0.53.tar.gz from apache.

# Decompress

Tarzxvf apache-tomcat-7.0.53.tar.gz

# Move to the corresponding directory and rename it to tomcat

Mvapache-tomcat-7.0.53/usr/local/tomcat7

# Edit the tomcat server configuration file, find appBase = "webapps", and modify the appBase value to your web page root directory.

Vim/usr/local/tomcat7/conf/server. xml

So, tomcat installation is complete. However, you need to assign a special user to tomcat, because if you run tomcat as root, tomcat has the system permission. Therefore, add a user tomcat that runs the service independently, and set the login to nologin to prevent the user from using the root permission to bring security risks to the system:

Useradd-d/usr/local/tomcat-s/usr/sbin/nologin tomcat

Chown-R tomcat: tomcat/usr/local/tomcat7

# Set boot start:

Vim/etc/rc. d/rc. local

# Add a line on the line of touch

/Usr/local/tomcat7/bin/startup. sh

After setting, if you are prompted that JAVA_HOME is not set, restart the VPS.
