Linux Tomcat Installation & configuration & Optimization

About Tomcat:

1.Tomcat is a software used to parse a JSP program. (JSP is a programming language, Java)

2.Tomcat is a core project of the Apache Software Foundation (Apache Software Foundation) Jakarta Project, developed by Apache, Sun, and other companies and individuals.

3.Tomcat is a lightweight application server , which is widely used in small and medium-sized systems and concurrent access users, and is the first choice for developing and debugging JSP programs.

The installation of Tomcat is divided into two steps: Installing the JDK and installing Tomcat.

Download The Java SE development to Oracle's website and select the version according to your system needs (http://211.161.151.150/files/A226000008F1B789/ download.oracle.com/otn-pub/java/jdk/8u111-b14/jdk-8u111-linux-x64.tar.gz)

Configuration and optimization of Tomcat

Tomcat starts with 8080 by default, and if you want to change to 80, you need to modify the Server.xml file:

[[email protected] ~]# cd/usr/local/tomcat/conf/ #进入到tomcat configuration file directory

[email protected] conf]# ls #查看

Catalina catalina.properties jaspic-providers.xml logging.properties tomcat-users.xml web. xml

Catalina.policy context.xml jaspic-providers.xsd server.xml tomcat-users.xsd

[Email protected] conf]# vim server.xml #编辑

<connector port= "8080" protocol= "http/1.1" # "8080" to "80"

connectiontimeout= "20000"

redirectport= "8443"/>

Find </Host> next line insert new <Host> content as follows:

appbase= "/data/tomcatweb" #网站的根目录

Unpackwars= "false" autodeploy= "true"

Xmlvalidation= "false" Xmlnamespaceaware= "false" >

<context path= "" docbase= "./" debug= "0" reloadable= "true" crosscontext= "true"/>

# "docbase="./"" The landlord here to copy some of the documents have been not experimental results

The path to the docBase is consistent with the Autodeploy path.

(You can also put the following 1.txt&1.jsp in this directory

" docbase="/usr/local/tomcat/webapps/docs ", can be parsed as normal access)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

find some explanations on the Internet

AppBase: Sets the base directory for the application, absolute path, or path name relative to%catalina_home%

Autodeploy: Indicates whether the Tomcat runtime, if a new Web program is opened appbase the specified directory, is automatic, and the default value is True

Deployxml: false will not resolve context.xml inside the Web application, the default value is True

unpackwars: The virtual host specifies the path name of the directory used for temporary read and write, and Tomcat will provide a suitable directory under the%catalina_home%/work directory.

docBase: The absolute path or relative path of the AppBase property relative to the host.

Use the Curl command to test under Linux : The following effect, you can access the 1.txt, you can also parse the JSP.

[Email protected] tomcatweb]# curl-xlocalhost:80 www.7_linux.com/1.txt

[Email protected] tomcatweb]# curl-xlocalhost:80 www.7_linux.com/1.jsp
