7. CentOS 7에 Apache (Httpd) 설치

아파치는 PHP를 단독으로 사용할 경우에 주로 사용한다.

JAVA를 이용할 경우 Tomcat에 부하를 줄여주기 위해 아파치와 연동해서 사용하기도 한다.

1. yum 명령어를 이용하여 apache를 설치한다.

[root@localhost soo]# yum install httpd
Loaded plugins: fastestmirror

2. Apache를 실행한다. (service httpd start)

[root@localhost soo]# service httpd start
Redirecting to /bin/systemctl start httpd.service
[root@localhost soo]#

3. 정상적으로 실행되었는지 상태를 확인한다. (service httpd status)

[root@localhost soo]# service httpd status
Redirecting to /bin/systemctl status httpd.service

4. 서버 재부팅시 자동으로 실행되도록 서비스 활성화 등록을 해놓는다.

[root@localhost soo]# systemctl enable httpd.service
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.
[root@localhost soo]#

5. 웹브라우저 주소창에 localhost를 입력하여 잘 구동되는지를 확인한다.

6. PHP를 사용할 경우 info.php 파일을 만들어 서버의 root에 넣고 확인해본다. (사전에 php설치가 되어있는 경우)

   1) httpd의 root로 이동

[root@localhost html]# cd /var/www/html

   2) info.php 파일을 만든다.

[root@localhost html]# vi  info.php

   3) 시스템 정보를 가져오는 php 함수만 입력한다.

   위 내용만 키보드의 i 를 치고 입력 후 :wq (저장후 나옴) 입력하고 나온다.

7. 웹브라우저에 http://localhost/info.php 를 입력해서 확인한다.
