========================================================== ==============

1: uninstall the built-in OpenJDK

2: Install JDK1.6

 

Refer:

Or the previous page:

(Intranet) CentOS uninstall the built-in OpenJDK and install the Sun JDK method.

Original article:

 

View the current system jdk: rpm-qa | grep jdk

Result:

[Root @ dc-01 java] # rpm-qa | grep jdk

Java-1.6.0-openjdk-1.6.0.0-1.45.1.11.1.el6.i686

 

Detach:

[Root @ dc-01 java] # yum-y remove java-1.6.0-openjdk-1.6.0.0-1.45.1.11.1.el6.i686

 

 

Wait for a while to Complete.

Download Sun's JDK. I downloaded

Jdk-6u37-linux-i586-rpm.bin

For a 64-bit system, download:

Jdk-6u37-linux-x64-rpm.bin

And other 64-bit dedicated packages

 

Create a java directory under the/usr directory and put the downloaded file under the/usr/java directory

Change the file to an executable file (chmod 777 ):

[Root @ dc-01 java] # chmod 777 jdk-6u37-linux-i586-rpm.bin

Then execute this file to install it:

Press Enter to continue .....

 

 

Press enter.

Done appears.

 

The installation is now complete.

 

Configure JDK:

Vi/etc/profile open the profile file and add the following at the end of the profile file:

JAVA_HOME =/usr/java/jdk1.6.0 _ 37 PATH = $ JAVA_HOME/bin: $ PATHCLASSPATH =.: $ JAVA_HOME/lib/dt. jar: $ JAVA_HOME/lib/tools. jarexport JAVA_HOMEexport PATHexport CLASSPATH

 

 

 

Save and close the profile file, and run the source/etc/profile command to make the modification take effect.

Run java-version to check the java version:

[Root @ dc-01 java] # java-version

Java version "1.6.0 _ 37" Java (TM) SE Runtime Environment (build 1.6.0 _ 37-b06) Java HotSpot (TM) Client VM (build 12-b01, mixed mode, sharing) [root @ dc-01 java] #

========================================================== ==========

 

So far, the entire installation process is complete.

 

3: install Tomcat

Download apache-tomcat-7.0.33.tar.gz. Decompress:

 

Tar-xzvf apache-tomcat-7.0.33.tar.gz

Copy the decompressed folder to/usr/local/tomcat:

Cp-R apache-tomcat-7.0.33/usr/local/tomcat

Go to the tomcat directory to set tomcat memory usage and other configurations:

Cd/usr/local/tomcat/bin

Vi daemon. sh

Add the following content at the beginning of the text (make sure to modify the jdk and other directories according to your actual situation ):

 

# Chkconfig: 2345 20 80 # description: simple example to start tomcatJAVA_HOME =/usr/java/jdk1.6.0 _ 37CATALINA_HOME =/usr/local/modules = "-Xms1024m-Xmx4096m-XX: permSize = 256 m-XX: MaxPermSize = 512 m"

4: Configure Tomcat to start in daemon mode

Copy daemon. sh to the startup directory, install the service, and test the service:

Compile and install commons-daemon first:

Install gcc first, because it is required during compilation.

Yum install gcc

Create a tomcat user to run the tomcat service:

Using root in the production environment is not safe, so

Useradd-s/sbin/nologin tomcat

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

Started with the operating system as a service

 

# Tar-xzvf commons-daemon-native.tar.gz

# Cd commons-daemon-1.0.10-native-src/unix

#./Configure

# Make

# Cp jsvc ../..

# Cd ../..

 

Cp daemon. sh/etc/init. d/tomcat

Chmod 755/etc/init. d/tomcat

Chkconfig -- add tomcat

Chkconfig tomcat on

Chkconfig -- list tomcat

Display:

Tomcat 0: off 1: off 2: on 3: on 4: on 5: on 6: off confirm 2 ~ 5. If the status is on, OK.

Start Tomcat:

Service tomcat start

Add firewall configuration to allow port 8080:

# Vi/etc/sysconfig/ipdables

Add one to allow ssh:

-A input-m state -- state NEW-m tcp-p tcp -- dport 8080-j ACCEPT

Save and restart the iptables service:

# Service iptables restart

 

Test:

Local test:

Wget http: // localhost: 8080/

Test from other machines:

Enter http: // localhost: 8080/in the browser/

Check whether the website can be opened.

# useradd -s /sbin/nologin tomcat # chown -R tomcat:tomcat /opt/tomcat7 

Started with the operating system as a service

# cd /opt/tomcat7/bin # tar -xzvf commons-daemon-native.tar.gz # cd commons-daemon-1.0.10-native-src/unix # ./configure # make # cp jsvc ../.. # cd ../.. 

After the daemon. sh comment, add the following five elements to the text

# vim daemon.sh ---- # chkconfig: 2345 10 90 # description: Starts and Stops the Tomcat daemon. JAVA_HOME=/usr/java/jdk1.6.0_31 CATALINA_HOME=/opt/tomcat7 CATALINA_OPTS="-Xms1024m -Xmx2048m -XX:PermSize=256m -XX:MaxPermSize=512m" 

Add to service

# cp daemon.sh /etc/init.d/tomcat # chkconfig --add tomcat 

Check

# Chkconfig -- list | grep tomcat 0: Disable 1: Disable 2: Enable 3: Enable 4: Enable 5: Enable 6: Disable
