Run the service on Tom

1. CD/usr/local/tomcat/

2. You can create several directories, called/tomcat/webapps, and create the libincia directory in webapps, and in this directory, create/WEB-INF and create/classes and/lib respectively under the WEB-INF, Which means we want to deploy a service.

Mkdir/tomcat/webapps-PV

CD webapps

Mkdir libincia

[[Email protected] libinlinoleic] # tree WEB-INF/
WEB-INF/
── Classes
── Lib

2 directories, 0 files

3. Create a file named index. jsp under the libincia directory (note the Directory) and check the effect.

4. Configure the main configuration file of Tomcat, which defines a new host or a new context to include the modified one.

Define a new host named libincla.clarinet.com

<Host name = "libincla.clarinet.com" appbase = "/tomcat/webapps"
Unpackwars = "true" autodeploy = "true">
</Host>

The default host is libincla.clarinet.com.

<Engine name = "Catalina" defaulthost = "libincla.clarinet.com">

Disable and start Catalina. Sh to view the effect

Scenario 2,

Here, the default host of the engine is modified in the previous operation. In this case, what should we do if we want to use the libincia service just defined and localhost?

Cut the/tomcat/webapps/libingroovy directory to/usr/local/tomcat/webapps.

[[Email protected] libincia] # cp-r/tomcat/webapps/libincia // usr/local/tomcat/webapps/

Edit/usr/local/tomcat/CONF/server again. XML file, and change the engine host back to localhost, remove the host defined below, and Catalina again. sh stop & Catalina. try sh start.

650) This. width = 650; "style =" border-right-0px; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px "Title =" image "border =" 0 "alt =" image "src =" http://img1.51cto.com/attachment/201409/29/6249823_1411997191cJTo.png "width =" 525 "Height =" 280 "/>

And through

650) This. width = 650; "style =" border-right-0px; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px "Title =" image "border =" 0 "alt =" image "src =" http://img1.51cto.com/attachment/201409/29/6249823_1411997225CuWT.png "width =" 538 "Height =" 253 "/>

In addition, all the statuses of the service are defined in the server status on the home page.

650) This. width = 650; "style =" border-right-0px; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px "Title =" image "border =" 0 "alt =" image "src =" http://img1.51cto.com/attachment/201409/29/6249823_1411997239DUuJ.png "width =" 552 "Height =" 267 "/> if this shows JVM running what are the heap memory of Java in?

If you do not want to deploy a new service by modifying the configuration file, you can

650) This. width = 650; "style =" border-right-0px; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px "Title =" image "border =" 0 "alt =" image "src =" http://img1.51cto.com/attachment/201409/29/6249823_1411997276njiT.png "width =" 553 "Height =" 375 "/> Add a new one directly by adding a button service options. This is a hot deployment of Tomcat, and this method is not recommended.

Scenario 3,

Write a script for Tomcat to control it, or add it to the service list to enable automatic startup.

#! /Bin/sh
# Tomcat init script for Linux
#
# Chkconfig 2345 19 88
# Java_opts = '-xms64m-xmx128m'
Java_home =/usr/Java/lastest
Catalina_home =/usr/local/tomcat
Export java_home catalina_home

Case $1 in
Start)
Exec $ catalina_home/bin/Catalina. Sh start ;;
Stop)
Exec $ catalina_home/bin/Catalina. Sh stop ;;
Restart)
Exec $ catalina_home/bin/Catalina. Sh stop
Sleep 3
Exec $ catalina_home/bin/Catalina. Sh start ;;
*)
Echo "make start or stop or restart"
Exit 1
;;
Esac

Then you can use the script to run and control tomcat.

If you want to define a new service in Tomcat, You need to define a new host. If you want to define an application instance in the service, you need to define a new context in the host, however, by default, in the Java definition, a service root directory is used to store the main configuration file of the service (note that this service is used ), each application is defined in another directory in the root directory.

Description of the reference context document:

Context component:
In some sense, context is similar to the path alias in Apache. A context definition is used to identify a web application in a tomcat instance. the following definition:
<! -- Tomcat root context -->
<Context Path = "" docbase = "/web/webapps"/>
<! -- Buzzin webapp -->
<Context Path = "/BBS"
Docbase = "/web/Threads/BBS"
Reloadable = "true">
</Context>
<! -- Chat Server -->
<Context Path = "/chat" docbase = "/web/chat"/>
<! -- Darian Web -->
<Context Path = "/Darian" docbase = "Darian"/>

In tomcat6, each context definition can also be performed using a separate XML file. The directory of the file is $ catalina_home/CONF/<engine Name>/<Host Name>. The XML elements in context can be loader, Manager, realm, resources, and watchedresource.

Common attributes are defined as follows:
1) docbase: The storage location of the corresponding web application. You can also use the relative path. The starting path is the path defined by appbase in the host to which the context belongs. Remember, the path name of docbase cannot be included with the path name defined in appbase of the corresponding host. For example, if appbase is deploy, docbase cannot be the name of the deploy-BBs class;
2) path: URI relative to the root path of the Web server. If it is null, it indicates the root path of the webapp. If context is defined in a separate XML file, this attribute does not need to be defined;
3) reloadable: whether to allow re-loading the web application class related to this context; the default value is false;

 

Scenario 3: deploy an application that can be applied.

3.1

For example, visit http://www.libincla.com/jct?forum

So Path = "/jct", docbase = "jct"

This environment is intended to deploy an application called javacenter_home.

[[Email protected] TMP] # ls javacenter_home_2.0_gbk.tar.bz2
Javacenter_home_2.0_gbk.tar.bz2

Edit the main configuration file of Tomcat and define a new host in the engine, as shown in figure

<Host name = "www.libincla.com" appbase = "/tomcat/webapps"
Unpackwars = "true" autodeploy = "true">
<Context Path = "/jct" docbase = "jct"/>

Decompress the javacenter service.

[[Email protected] TMP] # tar xf javacenter_home_2.0_gbk.tar.bz2

Then place it in the/tomcat/webapps directory named jct.

[[Email protected] TMP] # mv javacenter_home_2.0_gbk/tomcat/webapps/jct

JPS allows you to view

Then restart the access.

If Tom does not directly respond to the client, nginx will reverse proxy.

Let Tom work in the in-process model,That is, the response model of different processes in a host.Below ::

Steps:

1. Start nginx, define the nginx configuration file, and add the following entries:
