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/iptables

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.

Install Tomcat 7 on centos6

• Linux18
• Centos1
• Tomcat1

1. Download

 
# Wget http://mirror.bit.edu.cn/apache/tomcat/tomcat-7/v7.0.29/bin/apache-tomcat-7.0.29.tar.gz
 

2. Installation

# Tar-xzvf apache-tomcat-7.0.29.tar.gz # mv APACHE-Tomcat-7.0.29/opt/tomcat7 # cd/opt/tomcat7 # bin/startup. Sh
 

3. Configuration

Using root in the production environment is not safe, so

 
# 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 = 256 m-XX: maxpermsize = 512 M"
 

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
