설계 목표
네트워크 구성도.
네트워크 구성도의 192.168.10.143 IP Network에 웹서버를 설정하여 www.kst09.gor로 접속할 수 있도록 DNS에 추가하자.
[주의사항]
1. /home/web의 o 권한에 rx가 있어야 접근이 가능하다.
2. <Directory>....</Directoy> 이 원하는 파일에 설정이 되어있어야 한다.

[root@localhost conf]# cat httpd.conf # # This is the main Apache HTTP server configuration file. It contains the # configuration directives that give the server its instructions. # See <URL:http://httpd.apache.org/docs/2.2> for detailed information. # In particular, see # <URL:http://httpd.apache.org/docs/2.2/mod/directives.html> # for a discussion of each configuration directive. # # Do NOT simply read the instructions in here without understanding # what they do. They're here only as hints or reminders. If you are unsure # consult the online docs. You have been warned. # # Configuration and logfile names: If the filenames you specify for many # of the server's control files begin with "/" (or "drive:/" for Win32), the # server will use that explicit path. If the filenames do *not* begin # with "/", the value of ServerRoot is prepended -- so 'log/access_log' # with ServerRoot set to '/www' will be interpreted by the # server as '/www/log/access_log', where as '/log/access_log' will be # interpreted as '/log/access_log'. # # ServerRoot: The top of the directory tree under which the server's # configuration, error, and log files are kept. # # Do not add a slash at the end of the directory path. If you point # ServerRoot at a non-local disk, be sure to point the LockFile directive # at a local disk. If you wish to share the same ServerRoot for multiple # httpd daemons, you will need to change at least LockFile and PidFile. # ServerRoot "/app/apache" # # Listen: Allows you to bind Apache to specific IP addresses and/or # ports, instead of the default. See also the <VirtualHost> # directive. # # Change this to Listen on specific IP addresses as shown below to # prevent Apache from glomming onto all bound IP addresses. # #Listen 12.34.56.78:80 Listen 80 # # Dynamic Shared Object (DSO) Support # # To be able to use the functionality of a module which was built as a DSO you # have to place corresponding `LoadModule' lines at this location so the # directives contained in it are actually available _before_ they are used. # Statically compiled modules (those listed by `httpd -l') do not need # to be loaded here. # # Example: # LoadModule foo_module modules/mod_foo.so # <IfModule !mpm_netware_module> <IfModule !mpm_winnt_module> # # If you wish httpd to run as a different user or group, you must run # httpd as root initially and it will switch. # # User/Group: The name (or #number) of the user/group to run httpd as. # It is usually good practice to create a dedicated user and group for # running httpd, as with most system services. # User daemon Group daemon </IfModule> </IfModule> # 'Main' server configuration # # The directives in this section set up the values used by the 'main' # server, which responds to any requests that aren't handled by a # <VirtualHost> definition.

위 파일이 주석이 많아서 길게 느껴지지만 규칙은 한가지이다
<Directory "폴더 경로"> 는 주의사항에서 언급한 2번 항목이다.
<Directory "폴더경로"> Options Indexes FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory>
위는 4가지 설정이 되어 있는 것으로 세부 내용은 다음에 언급할 예정이다.
아래는 virtualHost를 입력하는 경우 사용되는데 이건 ... 그냥 팁.
<VirtualHost 접속 IP > DocumentRoot 홈디렉토리 ServerName IP또는 도메인명 <Directory "폴더경로"> Options Indexes FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory> </VirtualHost>
그렇다면 여기서 입력해야하는 "폴더 경로", "Directory"는 무엇을 입력 해야할까?
이는 web관리자의 아이디의 홈주소를 설정하면된다.
최소권한의 원칙이 중요한데 기존 httpd를 설치하면 /app에 있는 폴더 위치를 와야 작업이 가능하다는 문제가 발생한다. 시스템 관리자와 서버관리자가 동일한 폴더에 접속하게 되면 자격을 가진 사람의 실수 혹은 악의로 인해 파일이 망가질 수 있기 때문이다.
그래서 작업영역을 분리하기 위해 사용자에게 작업영역을 할 당해주는 위치를 "폴더 경로", " Directory"로 설정하면 된다. 사용자 계정을 만들었다면 해당 계정 사용위치를 찾아서 붙여 넣어준다.
<Directory "/home/web/httpd/db1"> Options Indexes FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory> <Directory "/home/web/httpd/db2"> Options Indexes FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory>
나는 web계정을 생성하여 db1과 db2를 설정하였기에 위와 같이 설정하였다.
[web@localhost httpd]$ ls -al 합계 4 drwxrwxr-x 5 web web 40 5월 7 11:22 . drwx---r-x. 17 web web 4096 5월 7 13:28 .. drwxrwxr-x 2 web web 24 5월 7 13:24 db1 drwxrwxr-x 2 web web 24 5월 7 13:28 db2 drwxrwxr-x 2 web web 24 5월 6 14:44 html
설정된 계정은 Other권한에 r,x권한이 있어야한다. 따라서 아래와 같이 설정하면 해결 할 수 있다. 이는 주의사항 1번에 해당하는 항목이다.
[web@localhost httpd]$ chmod o+rx -R ./
결과
[보안관련 결과 도출]
위와 같이 결과를 확인할 수 있다. 그러나!!! 만약 접근권한이 없다면 주의사항 1,2가 진행되었는지 확인이 필요하다!
