mod_cband 를 설치 해 보자 #1

mod_cband는 트래픽을 제어할 수 있는 아파치 모듈입니다.

설치 할 때마다 찾아 다니기 힘드니 정리를 해 두고자 이렇게..

(아파치 2.4.x 에서 mod_cband 설치하기)

1. 설치 파일을 구합니다. (mod-cband-0.9.7.5.tgz)

2. 압축을 풀죠

# tar -zxvpf mod-cband-0.9.7.5.tgz

3. 압축이 풀린 디렉토리로 이동합니다.

# cd mod-cband-0.9.7.5

4. 설치 준비를 합니다.

# ./configure --with-apxs=/home/apache/bin/apxs

(--with-apxs=/home/apache/bin/apxs 는 아파치 apxs의 경로입니다.)

5. 컴파일

make: *** [src/.libs/mod_cband.so] Error 1

...에러난다 -_-

apache 2.4.x 부터는 소스에서 수정 해줘야 할게 있다고 합니다.

6. 소스 수정

# vi src/mod_cband.c

위 이미지에 표시한 곳을 수정해야 합니다.

1333 라인 : remote_ip -> client_ip

1342 라인 : remote_ip -> client_ip

1362 라인 : remote_ip -> client_ip

1363 라인 : remote_ip -> client_ip

1365 라인 : remote_addr -> client_addr

(vi 에서 라인 보는 명령어 :set nu)

7. 다시 컴파일
