[Linux]Web apache2 서버 구축하기 2

앞에 글에서는 아파치를 설치하는 방법에대해 적어보았습니다.

이번글에는 웹서버를 돌리면서 필요한 설정들을 적어보도록하겟습니다.

먼저 기본적인 설정파일을 수정해보겠습니다.

$sudo vi /etc/apache2/apache2.conf

apache2.conf 파일을 열어보면

# Based upon the NCSA server configuration files originally by Rob McCool. # # This is the main Apache server configuration file.  It contains the # configuration directives that give the server its instructions. # See http://httpd.apache.org/docs/2.2/ for detailed information about # the directives. # # 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.   # # The configuration directives are grouped into three basic sections: #  1. Directives that control the operation of the Apache server process as a #     whole (the 'global environment'). #  2. Directives that define the parameters of the 'main' or 'default' server, #     which responds to requests that aren't handled by a virtual host. #     These directives also provide default values for the settings #     of all virtual hosts. #  3. Settings for virtual hosts, which allow Web requests to be sent to #     different IP addresses or hostnames and have them handled by the #     same Apache server process. # # 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 "foo.log" # with ServerRoot set to "/etc/apache2" will be interpreted by the # server as "/etc/apache2/foo.log". # ### Section 1: Global Environment # # The directives in this section affect the overall operation of Apache, # such as the number of concurrent requests it can handle or where it # can find its configuration files. # # # ServerRoot: The top of the directory tree under which the server's # configuration, error, and log files are kept. # # NOTE!  If you intend to place this on an NFS (or otherwise network) # mounted filesystem then please read the LockFile documentation (available # at <URL:http://httpd.apache.org/docs/2.2/mod/mpm_common.html#lockfile>); # you will save yourself a lot of trouble. # # Do NOT add a slash at the end of the directory path. # #ServerRoot "/etc/apache2" # # The accept serialization lock file MUST BE STORED ON A LOCAL DISK. # LockFile ${APACHE_LOCK_DIR}/accept.lock # # PidFile: The file in which the server should record its process # identification number when it starts. # This needs to be set in /etc/apache2/envvars # PidFile ${APACHE_PID_FILE} # # Timeout: The number of seconds before receives and sends time out. # Timeout 300 # # KeepAlive: Whether or not to allow persistent connections (more than # one request per connection). Set to "Off" to deactivate. # KeepAlive On # # MaxKeepAliveRequests: The maximum number of requests to allow # during a persistent connection. Set to 0 to allow an unlimited amount. # We recommend you leave this number high, for maximum performance. # MaxKeepAliveRequests 100 # # KeepAliveTimeout: Number of seconds to wait for the next request from the # same client on the same connection. # KeepAliveTimeout 5 ## ## Server-Pool Size Regulation (MPM specific) ##  # prefork MPM # StartServers: number of server processes to start # MinSpareServers: minimum number of server processes which are kept spare # MaxSpareServers: maximum number of server processes which are kept spare # MaxClients: maximum number of server processes allowed to start # MaxRequestsPerChild: maximum number of requests a server process serves <IfModule mpm_prefork_module>     StartServers          5     MinSpareServers       5     MaxSpareServers      10     MaxClients          150     MaxRequestsPerChild   0 </IfModule> # worker MPM # StartServers: initial number of server processes to start # MinSpareThreads: minimum number of worker threads which are kept spare # MaxSpareThreads: maximum number of worker threads which are kept spare # ThreadLimit: ThreadsPerChild can be changed to this maximum value during a #              graceful restart. ThreadLimit can only be changed by stopping #              and starting Apache. # ThreadsPerChild: constant number of worker threads in each server process # MaxClients: maximum number of simultaneous client connections # MaxRequestsPerChild: maximum number of requests a server process serves <IfModule mpm_worker_module>     StartServers          2     MinSpareThreads      25     MaxSpareThreads      75      ThreadLimit          64     ThreadsPerChild      25     MaxClients          150     MaxRequestsPerChild   0 </IfModule> # event MPM # StartServers: initial number of server processes to start # MinSpareThreads: minimum number of worker threads which are kept spare # MaxSpareThreads: maximum number of worker threads which are kept spare # ThreadsPerChild: constant number of worker threads in each server process # MaxClients: maximum number of simultaneous client connections # MaxRequestsPerChild: maximum number of requests a server process serves <IfModule mpm_event_module>     StartServers          2     MinSpareThreads      25     MaxSpareThreads      75      ThreadLimit          64     ThreadsPerChild      25     MaxClients          150     MaxRequestsPerChild   0 </IfModule> # These need to be set in /etc/apache2/envvars User ${APACHE_RUN_USER} Group ${APACHE_RUN_GROUP} # # AccessFileName: The name of the file to look for in each directory # for additional configuration directives.  See also the AllowOverride # directive. # AccessFileName .htaccess # # The following lines prevent .htaccess and .htpasswd files from being  # viewed by Web clients.  # <Files ~ "^\.ht">     Order allow,deny     Deny from all     Satisfy all </Files> # # DefaultType is the default MIME type the server will use for a document # if it cannot otherwise determine one, such as from filename extensions. # If your server contains mostly text or HTML documents, "text/plain" is # a good value.  If most of your content is binary, such as applications # or images, you may want to use "application/octet-stream" instead to # keep browsers from trying to display binary files as though they are # text. # # It is also possible to omit any default MIME type and let the # client's browser guess an appropriate action instead. Typically the # browser will decide based on the file's extension then. In cases # where no good assumption can be made, letting the default MIME type # unset is suggested  instead of forcing the browser to accept # incorrect  metadata. # DefaultType None # # HostnameLookups: Log the names of clients or just their IP addresses # e.g., www.apache.org (on) or 204.62.129.132 (off). # The default is off because it'd be overall better for the net if people # had to knowingly turn this feature on, since enabling it means that # each client request will result in AT LEAST one lookup request to the # nameserver. # HostnameLookups Off # ErrorLog: The location of the error log file. # If you do not specify an ErrorLog directive within a <VirtualHost> # container, error messages relating to that virtual host will be # logged here.  If you *do* define an error logfile for a <VirtualHost> # container, that host's errors will be logged there and not here. # ErrorLog ${APACHE_LOG_DIR}/error.log # # LogLevel: Control the number of messages logged to the error_log. # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg. # LogLevel warn # Include module configuration: Include mods-enabled/*.load Include mods-enabled/*.conf # Include all the user configurations: Include httpd.conf # Include ports listing Include ports.conf # # The following directives define some format nicknames for use with # a CustomLog directive (see below). # If you are behind a reverse proxy, you might want to change %h into %{X-Forwarded-For}i # LogFormat "%v:%p %h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" vhost_combined LogFormat "%h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" combined LogFormat "%h %l %u %t \"%r\" %>s %O" common LogFormat "%{Referer}i -> %U" referer LogFormat "%{User-agent}i" agent # Include of directories ignores editors' and dpkg's backup files, # see README.Debian for details. # Include generic snippets of statements Include conf.d/ # Include the virtual host configurations: Include sites-enabled/

이런식으로 나옵니다.

여기서 몆가지를 설정해보자면.

LockFile ${APACHE_LOCK_DIR}/accept.lock    // Lock 파일명 또는 파일경로를 지정하는 내용입니다.

PidFile ${APACHE_PID_FILE}                    //  프로세스ID 파일명과 파일의 위치를 지정하는 내용입니다.

Timeout 300                                   // 클라이언트가 웹서버에 접속한후 GET요청을 받을때까지 기다리는

기다리는 시간입니다 저시간이 지나가게되면 접속을 끊어버립니다

KeepAlive On                                   // 클라이언트가 웹사이트에 지속적인 접속 여부를 허용 여부 설정입니다.

지속적인 접속을 원치않을경우 OFF 로 바꿔줍니다

MaxKeepAliveRequests 100                           // KeepAlive On  으로 설정했을때 허용할 최대 요청수를 설정합니다.

KeepAliveTimeout 5                            // 다음번의 요청하기위한 대기시간을 설정합니다.

이번글에서는 apache2.conf 파일의 설정에대해 적어보았습니다.

다음글에서는 html 파일의 위치와 로그에대해 적어보도록하겟습니다.
