$ sudo yum install java-1.8.0-openjdk-devel

$ ls /usr/lib/jvm

$ export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-0.el7_5.x86_64

$ sudo sh -c "echo export JAVA_HOME==/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-0.el7_5.x86_64 >> /etc/environment"

$ export JRE_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-0.el7_5.x86_64/jre

$ export PATH=$PATH:/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-0.el7_5.x86_64/bin:/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-0.el7_5.x86_64/jre/bin

2) tomcat 설치

$ cd /opt

참고) https://downloads.apache.org/tomcat/tomcat-8 에 방문해서 최근 버전 확인할것

$wget https://downloads.apache.org/tomcat/tomcat-8/v8.5.54/bin/apache-tomcat-8.5.54.tar.gz

$ sudo tar xzf apache-tomcat-8.5.54.tar.gz

$ sudo mv apache-tomcat-8.5.54 /usr/share/tomcat8

$ ls /usr/share/tomcat8

$ ls /usr/share/tomcat8/bin

$ cd /usr/share/tomcat8/bin/

$ ./startup.sh

$ /usr/share/tomcat8/bin/startup.sh

3) 방화벽 해제

firewall-cmd --permanent --zone=public --remove-port=8080/tcp

firewall-cmd --get-zones

firewall-cmd --reload

4) http://192.168.10.10:8080/sample 웹 접속을 위한 WAR 배포

/usr/share/tomcat8> cp webapps/docs/appdev/sample/sample.war webapps/

bin> shutdown.sh

bin> startup.sh

RHEL 은 레드햇 상용 리눅스라, 유료 입력키가 없으면 레드햇 Repo (yum) 사용 불가 .

> yum repolist 로 확인

1) EC2 에서 key pair 생성하고, beanstalk 에서 앞서 생성한 key pair 를 등록해줘야 한다.

beanstalk > 구성 > 보안 에서 "편집" 클릭

2) pem 이면 openssh 로 접속가능하나 putty 에서는 안되므로, 다음부터는 ppk 로 생성해야 할 것 같다.

powershell > "ssh -i mykeypair.pem ec2-user@my-env.eba-a8r9c45u.ap-northeast-2.elasticbeanstalk.com"
