Java+tomcat Multi-instance configuration

Tomcat needs to work with the Java environment, so we need to install Java first (I'm using the java1.7.0 version here)

First, preparation: Download java1.7.0 compressed Package

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

1. Unzip the downloaded JDK source package and copy it to the specified directory

Mkdir/usr/local/java
#创建jdk存放目录

Tar XF jdk-7u79-linux-x64.tar.gz
#解压jdk源码包

CP Jdk-8u121-linux-x64/usr/local/java

#将jdk源码包拷贝到指定目录, this directory is specified according to its own custom

2. Uninstalling the system-installed Java environment

Rpm-qa | grep java*
#查询已安装的有关java的rpm包

Yum Remove-y java*

#卸载java

3. Add Java variables to environment variables so that all users can use the

Vim/etc/profile

##### #JAVA #####

java_home=/usr/lcoal/java/jdk1.7.0_79

Path= $JAVA _home/bin/tools.jar: $JAVA _home/libdt.jar

Classpath=.: $JAVA _home/lib/tools.jar: $JAVA _home/lib/dt.jar

Export PATH java_home CLASSPATH catalina_home

3.1 Updating environment variables

Source/etc/porfile

See if Java is configured successfully

[Email protected] opt]# java-version
Java Version "1.7.0_79"
Java (TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot (TM) 64-bit Server VM (build 24.79-b02, Mixed mode)

Second, configure Tomcat (Tomcat decompression can be used)

2.1 Unzip the apache-tomcat-7.0.57.tar.gz and rename it to Tomcat_one Tomcat_two

Tar XF apache-tomcat-7.0.57.tar.gz
#解压tomcat压缩包

CP apache-tomcat-7.0.57 Tomcat_one

CP apache-tomcat-7.0.57 Tomcat_two

2.2 Put the test page you wrote into the Tomcat Web file directory

#tomcat_one index.jsp "This is Tomcat_one"

#tomcat_two index.jsp "This is Tomcat_two"

#将tomcat自带的欢迎页面删除

RM-RF tomcat_one/webapps/root/*

#tomcat_one

CP index.jsp Tomcat_one/webapps/root

#tomcat_tow

CP index.jsp Tomcat_one/webapps/root

2.3 Single-machine deployment multiple instances need to modify Tomcat ports

Vim/tomcat/conf/server.xml

<server port= "8005" shutdown= "Shutdown" >

<connector port= "8080" protocol= "http/1.1"

<connector port= "8009" protocol= "ajp/1.3" redirectport= "8443"/>

Tomcat default port is: 8005 8009 8080, if multiple tomcat is deployed on one machine need to modify port to prevent port conflict

8005: Remote Stop service port

8009: Apache can over AJP protocol access to Tomcat's 8009 port for AJP port.

8080:http Access Port

2.4 Start Service (each tomcat comes with a start-stop script)

#停止服务脚本

sh/tomcat/bin/shutdown.sh

#启动服务脚本

sh/tomcat/bin/startup.sh

2.5 Detailed configuration refer to the following Web page:

2.6 Installation configuration complete, test

http://localhost:8080

http://localhost:8081
