Simple installation and summary of tomcat

There is no time to record tomcat finished a few days ago and it is relatively idle today. So let's make a brief summary and report an error to tomcat startup:

Error occurred during initialization of VM

Java/lang/NoClassDefFoundError: java/lang/Object

Make a summary. You can check the problem later to help you better understand it. You also hope to provide a solution for those who encounter the same error.

1. Download jdk and tomcat

Http://download.chinaunix.net/down.php? Id = 33932 & ResourceID = 61 & site = 1

Http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-6/v6.0.36/bin/apache-tomcat-6.0.36.tar.gz

2. Install the jdk Environment

[Root @ localhost src] # ls

Apache-tomcat-6.0.36.tar.gz debug jdk-6u26-dlj-linux-amd64.bin kernels

[Root @ localhost src] # chmod o + x jdk-6u26-dlj-linux-amd64.bin // Add the execution permission x to the jdk's other user, some versions will prompt for the next action after performing this step. There is no prompt for this version. We will perform the Next Step manually.

[Root @ localhost src] #./jdk-6u26-dlj-linux-amd64.bin // there will be a large heap prompt information after execution, the following will prompt you whether to execute the same:

Do you agree to the above license terms? [Yes or no]

Run yes.

After completion, a new directory is generated in the current directory: jdk1.6.0 _ 26

[Root @ localhost src] # ls

Apache-tomcat-6.0.36.tar.gz jdk1.6.0 _ 26 kernels

Debug jdk-6u26-dlj-linux-amd64.bin

[Root @ localhost src] # mkdir-p/usr/java // create a directory to build the jdk Environment

[Root @ localhost src] # mv jdk1.6.0 _ 26/usr/java/[root @ localhost src] # vim/etc/profile // modify environment variables, add the following content to the file:

Export JAVA_HOME =/usr/java/jdk1.6.0 _ 26

Export CLASSPATH = $ CLASSPATH: $ JAVA_HOME/lib: $ JAVA_HOME/jre/lib

Export PATH = $ JAVA_HOME/bin: $ JAVA_HOME/jre/bin: $ PATH: $ HOMR/bin

Source/etc/profile // make the environment variable take effect immediately

Java-version // check the java version to check whether the jdk is successfully installed.

3. install and configure tomcat

[Root @ localhost src] # tar zxvf apache-tomcat-6.0.36.tar.gz

[Root @ localhost src] # mv apache-tomcat-6.0.36/usr/local/tomcat_1

[Root @ localhost src] # cd/usr/local/tomcat_1/

[Root @ localhost tomcat_1] # ls

Bin lib logs RELEASE-NOTES temp work

Conf license notice RUNNING.txt webapps

[Root @ localhost tomcat_1] #./bin/startup. sh // start tomcat

Using CATALINA_BASE:/usr/local/tomcat_1

Using CATALINA_HOME:/usr/local/tomcat_1

Using CATALINA_TMPDIR:/usr/local/tomcat_1/temp

Using JRE_HOME:/usr/java/jdk1.6.0 _ 26

Using CLASSPATH:/usr/local/tomcat_1/bin/bootstrap. jar

[Root @ localhost tomcat_1] # java // execute the java command

Error occurred during initialization of VM

Java/lang/NoClassDefFoundError: java/lang/Object // error. It seems that a vm error occurs during initialization.

[Root @ localhost tomcat_1] # ps-ef | grep java | grep-v grep // NO content is displayed after execution, no process [root @ localhost tomcat_1] # netstat-nutpl | grep 8080 // check whether tomcat port 8080 is started. If no content is displayed, port 8080 is not started, that is to say, tomcat is not started. Think twice !! [Root @ localhost tomcat_1] # cat. /logs/catalina. out // view tomcat's logs Log File Error occurred during initialization of VMjava/lang/NoClassDefFoundError: java/lang/Object after google, with high guidance, the result is: 4. solution Error: Error occurred during initialization of VMjava/lang/NoClassDefFoundError: java/lang/Object

[Root @ localhost tomcat_1] # cd/usr/java/jdk1.6.0 _ 26/lib/

[Root @ localhost lib] # ls

Ct. sym htmlconverter. jar jconsole. jar orb. idl tools. pack

Dt. jar ir. idl jexec sa-jdi.jar visualvm

[Root @ localhost lib] # unpack200 tools. pack tools. jar // convert the file type

[Root @ localhost lib] # cd/usr/java/jdk1.6.0 _ 26/jre/lib/

[Root @ localhost lib] # ls

Rt. pack // find the file under the Directory and run the following command: [root @ localhost lib] # unpack200 rt. pack rt. jar [root @ localhost lib] # javaUsage: java [-options] class [args...] (to execute a class) or java [-options]-jar jarfile [args...] (to execute a jar file )........... // there is still a lot of content later. It is not posted here and can be executed by java commands.

[Root @ localhost lib] #/usr/local/tomcat_1/bin/startup. sh // start tomcat again

Using CATALINA_BASE:/usr/local/tomcat_1

Using CATALINA_HOME:/usr/local/tomcat_1

Using CATALINA_TMPDIR:/usr/local/tomcat_1/temp

Using JRE_HOME:/usr/java/jdk1.6.0 _ 26

Using CLASSPATH:/usr/local/tomcat_1/bin/bootstrap. jar

[Root @ localhost lib] # netstat-ntl // check whether port 8080 of tomcat is enabled

Active Internet connections (only servers)

Tcp 0 0: 8080: * LISTEN tcp 0: 22: * LISTEN tcp 0: 1: 631 ::: * LISTEN tcp 0 0: 1: 25: * LISTEN tcp 0 0: 55001: * LISTEN tcp 0: ffff: 127.0.0.1: 8005 ::: * LISTEN tcp 0 0: 8009: * LIS

OK. Our port 8080 is up.

[Root @ localhost lib] # ps-ef | grep java | grep-v grep // check whether a java Process exists.

OK, the process also exists. Next we will check in the browser for access:

OK. Our apache fault has been resolved and can be accessed.

If you can see it, it is also a compliment to me. Thank you for your attention.
