// 압축 해제
# tar zxvf apache-tomcat-8.5.27.tar.gz

// 압축 해제한 톰캣을 /usr/local/tomcat8 경로로 이동
# mv apache-tomcat-8.5.27 /usr/local/tomcat8

2. 환경변수 등록

vi /etc/profile

//하단에 입력
...

JAVA_HOME=/usr/lib/jvm/java-11-openjdk-11.0.11.0.9-1.el7_9.x86_64
CATALINA_HOME=/usr/local/tomcat8
CLASSPATH=$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar:$CATALINA_HOME/lib-jsp-api.jar:$CATALINA_HOME/lib/servlet-api.jar
PATH=$PATH:$JAVA_HOME/bin:/bin:/sbin
export JAVA_HOME PATH CLASSPATH CATALINA_HOME

설정 후 명령어 입력
source /etc/profile

3. server.xml 설정

vi /usr/local/tomcat8/conf/server.xml

// 아래 설정에서 URIEncoding="UTF-8" 추가

...

4. Tomcat 8 실행

// startup.sh 로 톰캣서버를 실행
# /usr/local/tomcat8/bin/startup.sh

or

# $CATALINA_HOME/bin/startup.sh

• 실행확인

Using CATALINA_BASE:   /usr/local/tomcat8
Using CATALINA_HOME:   /usr/local/tomcat8
Using CATALINA_TMPDIR: /usr/local/tomcat8/temp
Using JRE_HOME:        /usr/lib/jvm/java-11-openjdk-11.0.11.0.9-1.el7_9.x86_64
