Tomcat 8 install

Ubuntu 기준으로 tomcat8 설치하기

JDK8

$ apt-cache search openjdk-8
$ apt-get install openjdk-8-jdk
$ java -version
openjdk version 1.8.0_222

설치 경로 확인

$ upate-alternatives --list java
/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java
$ cd /usr/lib
$ ln -s jvm/java-8-openjdk-amd64 java
$ ls /usr/lib/java

tomcat8

tomcat은 패키지를 apt-get으로 설치하면 자동으로 설정이 되는 장점이 있지만, 수동으로 받아서 설치하는 것이 좋다. (개인 취향)
수동으로 하는 것은 설치 경로나 구성 등을 본인에 맞게 할 수 있다.

간략 버전 (빠른 설치)

sudo apt-get install tomcat8
ufw allow 8080
service tomcat8 start
끝

수동 설치
http://tomcat.apache.org
홈페이지에서 원하는 버전의 다운로드 URL을 복사한다.

# cd /usr
# wget https://archive.apache.org/dist/tomcat/tomcat-8/v8.5.9/bin/apache-tomcat-8.5.9.tar.gz
# tar xvfz apache*.gz
# ln -s apache-tomcat-8.5.9 tomcat
# cd /usr/tomcat/bin
# ./version.sh
Apache Tomcat/8.5.9

환경 설정

방화벽 오픈
ufw allow 8080
환경 변수

$ vi /etc/profile
export JAVA_HOME=/usr/lib/java
export CATALINA_HOME=/usr/tomcat
export CLASSPATH=.:$JAVA_HOME/jre/lib/ext:$JAVA_HOME/lib/tools.jar:$CATALINA_HOME/lib/jsp-api.jar:$CATALINA_HOME/lib/servlet-api.jar 

$ source /etc/profile

구동 테스트
cd /usr/tomcat/bin
./startup.sh
netstat -ant | grep 8080
ps -ef | grep tomcat

브라우저에서 http://IP:8080 으로 접속하여 페이지가 뜨는지 확인한다.

테스트 종료
./shutdown.sh

부팅시 자동시작 스크립트

/etc/init.d에 tomcat 파일을 아래와 같이 만들고
chomd 755 tomcat으로 권한을 설정한다.
JAVA_HOME, CATALINA_HOME, tomcat 계정, 디렉터리를 잘 설정한다.
