Building a web test environment under linuxFirst, JDK installation
1, jdk-7-ea-bin-b26-linux-i586-24_apr_2008.bin
address:
Extract the zip format from jdk-7-ea-bin-b26-linux-i586-24_apr_2008.bin under windows
Then pass to the /usr/java directory of linux
2, add executable permissions to the file
[root@localhost java]# chmod +x jdk-7-ea-bin-b26-linux-i586-24_apr_2008.bin
3. Execute jdk-7-ea-bin-b26-linux-i586-24_apr_2008.bin
[root@localhost java]# . /jdk-7-ea-bin-b26-linux-i586-24_apr_2008.bin
Automatic installation build directory jdk1.7.0
4. Configure environment variables
There are three ways to configure environment variables (respectively: modify the /etc/profile file, modify the .bashrc file in the user directory, and modify it directly under the shell). I modified the /etc/profile file:
[root@localhost java]# vi /etc/profile
After opening the file, press i to add after the file:
JAVA_HOME=/usr/java/jdk1.7.0
PATH=$JAVA_HOME/bin:$PATH
CLASSPATH=. :$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar
Export JAVA_HOME PATH CLASSPATH
Press esc
Type: wq to save and exit.
Restart the server
6. Test the configuration environment
Write a simple HelloWorld to test it out
[root@localhost java]# vi HelloWorld.java
Enter in the file:
Public class HelloWorld
}
:wq save exit
[root@localhost java]# javac HelloWorld.java
No errors, then:
[root@localhost java]# java HelloWorld
Output under the shell:
Exception in thread "main" java.lang.NoClassDefFoundError: HelloWorld/java
Caused by: java.lang.ClassNotFoundException: HelloWorld.java
At java.net.URLClassLoader$1.run
At java.net.URLClassLoader$1.run
At java.security.AccessController.doPrivileged
At java.net.URLClassLoader.findClass
At java.lang.ClassLoader.loadClass
At sun.misc.Launcher$AppClassLoader.loadClass
At java.lang.ClassLoader.loadClass
At java.lang.ClassLoader.loadClassInternal
Error: Could not find the main class.
Error: A JNI error has occurred, please check your installation and try again
(The above question is what the reason is, but it does not seem to affect the operation of the following jsp ^_^ Let's count as jdk installation success.)
Second, tomcat installation: (also installed in the /usr/java directory)
1. Extract to the /usr/java directory:
[root@localhost java]# tar -zxvf jakarta-tomcat-5.0.28.tar.gz
A new directory jakarta-tomcat-5.0.28 will appear in the /usr/java directory.
2. Create a file link:
[root@localhost java]# ln -s jakarta-tomcat-5.0.28 tomcat
3. Configure CATALINA_HOME:
[root@localhost java]# vi /etc/profile
Add at the end of the file
CATALINA_HOME=/usr/java/tomcat
Export CATALINA_HOME
:wq save exit
4, start tomcat:
[root@localhost tomcat]# bin/startup.sh
Output under the shell:
Using CATALINA_BASE: /usr/java/tomcat
Using CATALINA_HOME: /usr/java/tomcat
Using CATALINA_TMPDIR: /usr/java/tomcat/temp
Using JAVA_HOME: /usr/java/jdk1.7.0
5, enter in the browser: willmcat page will appear
6, manage tomcat:
[root@localhost tomcat]# vi conf/tomcat-users.xml
Add between tomcat-users and /tomcat-users:
User username=â€admin†password=â€admin†roles=â€admin,managerâ€/
7, restart the system:
Enter in the browser: http://localhost:8080/admin After logging in, you can manage it.
