우분투 (Ubuntu) 22.04 nginx + Apache 동시 사용하기

1. nginx apache 포트 체크 및 에러

netstat -tnlp

---

2. nginx 서비스 중 apache 서비스 시작 오류 

* nginx apache 2개 서비스는 기본적으로 80포트를 이용하기 때문에 충돌이 발생하면서 오류 발생

<해결>

3. nginx 포트 변경

 

<3-1 포트 변경>

vi /etc/nginx/sites-enabled/default

 

server {
        listen 80 default_server;
        listen [::]:80 default_server;

-> 80번 포트를 3000으로 변경 

server {
        listen 3000 default_server;
        listen [::]:3000 default_server;

 

---

4. nginx 재시작

systemctl restart nginx //nginx 재시작

netstat -tnlp  // 포트체크

nginx가 80포트에 3000포트로 변경 확인

---

5. apache 재시작

systemctl restart apache2

---

6. 최종확인

nginx apache 두 서비스 실행 중 확인

 

netstat -tnlp // 포트 확인

tcp        0      0 0.0.0.0:3000            0.0.0.0:*               LISTEN      4756/nginx: master  
tcp6       0      0 :::3000                 :::*                    LISTEN      4756/nginx: master  
tcp6       0      0 :::80                   :::*                    LISTEN      4779/apache2        

*nginx 3000포트 

*apache 80포트
