1. Introduction of Tomcat

The origin of the name: Tomcat was originally developed by James Duncan Davidson, a software architect at Sun (Baidu for details). Tomcat server is a free and open source Web application server, which is a lightweight application server. It is used in small and medium-sized systems and where concurrent access is not many.

II. Deployment and implementation

1. Implementation environment

Host operating system IP address main software Tomcat server CentOS-7-x86_64

192.168.1.10

Jdk-7u65-linux-x64.gz

Apache-tomcat-7.0.54.tar.gz

two。 Implementation preparation

JDK must be installed before Tomcat can be installed. JDK, whose full name is Java Development Kit, is a free Java language software development kit provided by Sun, which includes Java Virtual Machine (JVM). The written Java source program can be compiled to form Java bytecode. As long as you install JDK, you can use JVM to interpret these byte files, thus ensuring the cross-platform nature of Java. In terms of platform compatibility, JDK, as a Java virtual machine that interprets bytecode files and calls operating system API to implement application functions, is closely related to the type of operating system and the number of platform bits, so there are different versions, and Tomcat also has the above characteristics, so you need to download JDK and Tomcat first. The versions of this software are as follows:

JDK:jdk-7u65-linux-x64.gz

Tomcat:apache-tomcat-7.0.54.tar.gz

3. Install JDK and configure the java environment

(1) decompress jdk-7u65-linux-x64.gz.

[root@localhost ~] # tar xf jdk-7u65-linux-x64.gz

(2) after decompression, the jdk1.7.0_65 folder will be moved to / usr/local/ and renamed to java (the / usr/local directory mainly stores some packages installed through the source code package, similar to program files under WINDOWS).

[root@localhost ~] # mv jdk1.7.0_65/ / usr/local/java

(3) create a java.sh script () under / etc/profile.d/.

[root@localhost ~] # vim / etc/profile.d/java.sh

Export JAVA_HOME=/usr/local/java / / set the Java root directory

Export PATH=$PATH:$JAVA_HOME/bin / / add the / bin subdirectory of the Java root directory to the PATH environment variable

(4) Import the java.sh script into the environment variable to make it effective.

[root@localhost ~] # source / etc/profile.d/java.sh

(5) run the java-version command or the javac-version command to see if the Java version is the same as previously installed.

[root@localhost ~] # java-version

Java version "1.7.0,65"

Java (TM) SE Runtime Environment (build 1.7.0_65-b17)

Java HotSpot (TM) 64-Bit Server VM (build 24.65-b04, mixed mode)

Or

[root@localhost ~] # javac-version

Javac 1.7.0_65

At this point the Java environment has been configured.

4. Install and configure Tomcat

(1) decompress the apache-tomcat-7.0.54.tar.gz package.

[root@localhost ~] # tar xf apache-tomcat-7.0.54.tar.gz

(2) generate an apache-tomcat-7.0.54 folder after decompression, move the folder to / usr/local/, and rename it to tomcat7.

[root@localhost ~] # mv apache-tomcat-7.0.54 / usr/local/tomcat7

(3) start tomcat

[root@localhost ~] # / usr/local/tomcat7/bin/startup.sh

Using CATALINA_BASE: / usr/local/tomcat7

Using CATALINA_HOME: / usr/local/tomcat7

Using CATALINA_TMPDIR: / usr/local/tomcat7/temp

Using JRE_HOME: / usr/local/java

Using CLASSPATH: / usr/local/tomcat7/bin/bootstrap.jar:/usr/local/tomcat7/bin/tomcat-juli.jar

Tomcat started.

Close tomcat

[root@localhost conf] # / usr/local/tomcat7/bin/shutdown.sh

Using CATALINA_BASE: / usr/local/tomcat7

Using CATALINA_HOME: / usr/local/tomcat7

Using CATALINA_TMPDIR: / usr/local/tomcat7/temp

Using JRE_HOME: / usr/local/java

Using CLASSPATH: / usr/local/tomcat7/bin/bootstrap.jar:/usr/local/tomcat7/bin/tomcat-juli.jar

/ usr/local/tomcat7/bin/catalina.sh: line 437: / usr/local/java/bin/java: cannot execute binary file

Tomcat runs on port 8080 by default. Run the netstat command to view the listening information on port 8080.

[root@localhost ~] # netstat-anpt | grep 8080

Tcp6 0 0: 8080: * LISTEN 2328/java Port 8080 needs to be opened because the firewall is enabled

[root@localhost] # iptables-I INPUT-p tcp-m multiport-- dport 8080-j ACCEPT

[root@localhost] # iptables-I INPUT-p tcp-m state-- state ESTABLISHED-j ACCEPT

[root@localhost ~] # iptables-p INPUT DROP

Iptables v1.4.21: unknown protocol "input" specified

Try `iptables-h' or 'iptables-- help' for more information.

III. Instructions on Tomcat configuration

The home directory of Tomcat is / usr/local/tomca7/.

Home directory description

|-bin/: stores script files for starting and shutting down Tomcat on windows or linux platforms.

|-conf/: stores various global configuration files of tomcat server, the most important of which are server.xml and web.xml.

|-lib/: stores the library files (JARS) needed for tomcat operation.

|-logs/: stores the LOG file when Tomcat executes.

|-webapps/:Tomcat 's main Web publishing directory.

|-work/: stores the class file generated by jsp compilation.

Profile description

Server.xml: the main configuration file. By changing this file, you can modify the startup port of Tomcat, website directory, virtual host, open https and other important functions.

Catalina.policy: permission control profile.

Catalina.properties:tomcat property profile.

Logging.propertiess: log log related configuration files.

Tomcat-users.xml:manager-gui manages user profiles (after tomcat installation, it provides an administrative interface for manager-gui, through which configuration can enable access).

Servlet, servlet-mapping, filter, MIME and other related configurations of web.xml:Tomcat.

Extended understanding: main profile server component description

The whole server.xml consists of the following structures:,.

Come on, boy, don't let your wishes turn into regrets.
