Tomcat 7 with Java 8 with Raspberry Pi

Question

업데이트 tomcat8은 필요에 따라/manager/page를 열 수 있으므로이 시나리오에서 작동하는 것 같습니다. 이 방법으로 원래의 문제 상태를 해결할 수는 없지만이 시나리오에서는 debian 백 포트의 tomcat8을 사용하는 것이 좋습니다!

Raspbian 내가 tomcat7 not compiling jsp examples에 따른 작동해야

root@raspberrypi:/etc/apt# dpkg -l |grep tomcat 
ii libtomcat7-java      7.0.56-1~bpo70+2      all   Servlet and JSP engine -- core libraries 
ii tomcat7        7.0.56-1~bpo70+2      all   Servlet and JSP engine 
ii tomcat7-admin       7.0.56-1~bpo70+2      all   Servlet and JSP engine -- admin web applications 
ii tomcat7-common      7.0.56-1~bpo70+2      all   Servlet and JSP engine -- common files 

이다 데비안 백 포트에 의해 제공 tomcat7 버전으로 되돌릴 톰캣 (7)을 설치 한 후 버전

root@raspberrypi:/etc/apt# java -version 
java version "1.8.0" 
Java(TM) SE Runtime Environment (build 1.8.0-b132) 
Java HotSpot(TM) Client VM (build 25.0-b70, mixed mode) 

에서 현재의 Java (8)을 제공한다. 관리자 페이지에서 다음과 같은 오류를 남기므로이 경우가 아닙니다.

실제로 문제가 될 수있는 사람은 누구입니까?

질문에서 언급했듯이 Raspbian에서 제공하는 Tomcat은 Java 8에서 작동하지 않습니다. this blog의 지침에 따라 Tomcat 8을 설치할 수있었습니다. linkrot를 방지하고 작은 실수를 해결하기 위해, 나는 (버전 8.0.24 업데이트) 거의 문자 그대로의 텍스트를 인용합니다 :

Installing Apache Tomcat 8 on a Raspberry Pi

On my Raspberry Pi I have already installed Apache 2 HTTP server and hence this article does a basic install and configuration of Tomcat. Firstly, update all installed packages:

$ sudo apt-get update 

Confirm that Java is already installed:

pi@raspberrypi /usr/bin $ java -version 
java version "1.8.0" 
Java(TM) SE Runtime Environment (build 1.8.0-b132) 
Java HotSpot(TM) Client VM (build 25.0-b70, mixed mode) 

Log in to the home directory for the pi user and download the desired release of Tomcat:

$ wget http://mirrors.axint.net/apache/tomcat/tomcat-8/v8.0.24/bin/apache-tomcat-8.0.24.tar.gz 

Extract the zipped tarball:

$ tar xvf apache-tomcat-8.0.24.tar.gz 

Add the following user XML element as the last child of the tomcat-users parent element of ~/apache-tomcat-8.0.24/conf/tomcat-users.xml (this creates an admin account called “system” who’s password is “raspberry”):

<user username="system" password="raspberry" roles="manager-gui"/> 

Change the directory permissions on the following directorys, since by default, the pi Linux user cannot write to them:

[NB: I didn't have to do this step, as in release 8.0.24, there was no directory apache-tomcat-8.0.24/work/Catalina ]

Add a startup script called tomcat to the /etc/init.d directory, which has the following contents:

#!/bin/sh 
# /etc/init.d/tomcat 
# starts the Apache Tomcat service 
### BEGIN INIT INFO 
# Provides:   tomcat 
# Required-Start: 
# Required-Stop: 
# Default-Start:  2 3 4 5 
# Default-Stop:  0 1 6 
# X-Interactive:  true 
# Short-Description: Start/stop tomcat application server 
### END INIT INFO 

export CATALINA_HOME="/home/pi/apache-tomcat-8.0.24" 
case "$1" in 
start) 
    if [ -f $CATALINA_HOME/bin/startup.sh ]; 
    then 
    echo $"Starting Tomcat" 
    /bin/su pi $CATALINA_HOME/bin/startup.sh 
    fi 
    ;; 
stop) 
    if [ -f $CATALINA_HOME/bin/shutdown.sh ]; 
    then 
    echo $"Stopping Tomcat" 
    /bin/su pi $CATALINA_HOME/bin/shutdown.sh 
    fi 
    ;; 
*) 
    echo $"Usage: $0 {start|stop}" 
    exit 1 
    ;; 
esac 

Use the update-rc.d command to add the appropriate links to the /etc/rc?.d directories:

$ sudo update-rc.d tomcat defaults 

Test that the tomcat server starts:

$ sudo /etc/init.d/tomcat start 

On a web client, point your browser at http://”Raspberry Pi IP Address”:8080

Test that the tomcat server stops:

$ sudo /etc/init.d/tomcat stop 

Finally, reboot the system and the Tomcat application server should now start automatically on startup, and likewise when the system shuts down.
