- http://stackoverflow.com/questions/3589562/why-maven-what-are-the-benefits

4. JDK (Java SE Development Kit 8u91)

- http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
- After installation, set environment variable

- JAVA_HOME : C:\Program Files\Java\jdk1.8.0_91
- PATH : %JAVA_HOME%\bin
- CLASSPATH : .;%JAVA_HOME%\lib\tools.jar

5. Tomcat (apache-tomcat-9.0.0.M9)

- http://tomcat.apache.org/
- After download Tomcat, unzip in Java folder
- set environment variable

- CATALINA_HOME : C:\Program Files\Java\Tomcat 9.0
- PATH : %CATALINA_HOME%\bin

- exec C:\Program Files\Java\Tomcat 8.5\bin\startup
- check http://localhost:8080/

6. Apache (httpd-2.4.23-win64-VC14)

- https://www.apachelounge.com/download/
- After unzip, relocate C drive : C:\Apache24

7. Connect with tomcat

- http://apache.tt.co.kr/tomcat/tomcat-connectors/jk/binaries/windows/
- download connector using mod_jk

1) Copy mod_jk.so file to C:\Apache24\modules
2) Check server.xml



<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

3) Create workers.properties file at C:\Apache24\conf

worker.list=worker1

worker.worker1.type=ajp13

worker.worker1.host=localhost

worker.worker1.port=8009

4) Set some parameters to httpd.conf file

LoadModule jk_module modules/mod_jk.so

JkWorkersFile conf/workers.properties

JkLogFile logs/mod_jk.log

JkLogLevel info

JkMount /* worker1

* Refer to : http://joont.tistory.com/55

c.f)

* vcruntime140.dll error

- https://ko.dll-files.com/

- download and copy to C:\Windows\System32

* make annotation (전체 주석)

- C:\Apache24\conf\extra\httpd-vhosts.conf

* 시스템 효용성 및 분산 처리를 위해서 apache 와 tomcat을 연동
( WEB Server -> html, WAS Server -> jsp )
* 최신라이브러리 관리와 프로젝트 관리를 위해 Maven 사용
