Install and configure Tomcat8.0 in Linux/CentOS7.0

Install and configure Tomcat8.0 in Linux/CentOS7.0

Install and configure Tomcat8.0 in Linux/CentOS7.0

1. Configure the Tomcat installation environment

1. Download the corresponding jdk

Http://www.Oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

I use 64-bit:

Http://download.oracle.com/otn-pub/java/jdk/8u40-b25/jdk-8u40-linux-x64.tar.gz

Download and compress the jdk to the/usr/local directory:

2. Establish a jdk soft connection under/usr/local/to facilitate later version upgrades:

# Ln-s/usr/local/jdk1.8.0 _ 40 // usr/local/jdk

3. Environment Variables

Add the following content to/etc/profile:

JAVA_HOME =/usr/local/jdk1.8.0 _ 40

JAVA_BIN =/usr/local/jdk1.8.0 _ 40/bin

PATH = $ PATH: $ JAVA_BIN

CLASSPATH = $ JAVA_HOME/lib/dt. jar: $ JAVA_HOME/lib/tools. jar

Export JAVA_HOME JAVA_BIN PATH CLASSPATH

Save and exit

[Root @ master ~] Source/etc/profile

Check whether java environment variables take effect

[Root @ localhost local] # java-version

Java version "1.7.0 _ 51"

OpenJDK Runtime Environment (rhel-2.4.5.5.el7-x86_64 u51-b31)

OpenJDK 64-Bit Server VM (build 24.51-b03, mixed mode)

Note: When I configure the JAVA environment variable, JDK is jdk1.8.0 _ 40. When I run java-version, I get 1.7.0 _ 51.

This indicates that the JAVA environment variables in gcj in the system are given priority to execution. The solution is as follows:
Export PATH = $ JAVA_HOME/bin: $ PATH. Put $ PATH to the end. (If it is placed at the beginning, the above problem will occur)

# Java-version
Java version "1.8.0 _ 40"
Java (TM) SE Runtime Environment (build 1.8.0 _ 40-b25)
Java HotSpot (TM) 64-Bit Server VM (build 25.40-b25, mixed mode)

You can uninstall it before installation:

[Root @ local src] # rpm-qa | grep java

Java-1.7.0-openjdk-1.7.0.65-2.5.1.2.el6_5.x86_64

Rpm-e java-version-openjdk-devel depends on your version.

Ii. Tomcat8.0.20:

Http://mirrors.cnnic.cn/apache/tomcat/tomcat-8/v8.0.20/bin/apache-tomcat-8.0.20.tar.gz

# Tar xzf apache-tomcat-8.0.20.tar.gz // unzip

# Mv apache-tomcat-8.0.20/usr/local/tomcat

# Vim/usr/local/tomcat/bin/catalina. sh

Add: CATALINA_HOME =/usr/local/tomcat
Chmod + x *. sh

Iii. Start the tomcat server

1. Firewall allow 80

#/Etc/sysconfig/iptables // open it with VI

-A input-p tcp-m state-state NEW-m tcp-dport 80-j ACCEPT // Add this statement to allow 80

# Cd/usr/local/tomcat/bin/

#./Startup. sh // start tomcat

4. Enter test in the browser

Http: // localhost: 8080 (if it is not the local machine, enter the corresponding IP address)

If the tomcat page appears during the test, the test is successful!

5. Modify the port and add an application for testing

Ps: It should be noted that the default test page of tomcat is placed under webapps. This is actually configured in the server. xml file, as shown below:

<Host name = "192.168.1.8" appBase = "webapps"

UnpackWARs = "true" autoDeploy = "true">

</Host>

1) The webapps folder is mainly used for web Application Deployment. For example, you can copy your application package, such as a war file, to this directory, and the container will be automatically deployed.
2) In the conf folder, the configuration files of tomcat servers are mainly placed.

 

<Server port = "8005" shutdown = "SHUTDOWN"> // close the tomcat port.

<Connector port = "8080" protocol = "HTTP/1.1"

ConnectionTimeout = "20000"

RedirectPort = "8443"/> // default tomcat port 8080. Change to 80

<Connector port = "8009" protocol = "AJP/1.3" redirectPort = "8443"/> // port used to access tomcat in apache + tomcat Mode
