Hello World!!

======利用spawn-fcgi管理服務執行cgi程式====== spawn-fcgi是管理CGI程序的程式，它本來是[[wp>Lighttpd]](Web Server)其中一部分，現在它獨立出來可以供其他Web Server使用。若要知道其他更多cgi差異可以看這篇[[http://cecilyen.blogspot.com/2011/11/cgifastcgiphp-cgiphp-fpmspawn-fcgi.html|什麼是CGI、FastCGI、PHP-CGI、PHP-FPM、Spawn-FCGI？]] =====需要套件===== 本實作是搭配Nginx Web服務(Nginx是編譯安裝)。 * fcgi * fcgi-devel * fcgiwrap * spawn-fcgi =====安裝===== * 安裝fcgi 、 fcgi-devel及spawn-fcgi#yum install fcgi fcgi-devel spawn-fcgi * 安裝fcgiwrap

#cd /usr/local/src/
#git clone git://github.com/gnosek/fcgiwrap.git
#cd fcgiwrap
#autoreconf -i
#./configure
#make && make install

=====spawn-fcgi設定檔配置===== #vim /etc/sysconfig/spawn-fcgi FCGI_SOCKET=/var/run/fcgiwrap.socket FCGI_PROGRAM=/usr/local/sbin/fcgiwrap FCGI_USER=nginx FCGI_GROUP=nginx FCGI_EXTRA_OPTIONS="-M 0700" OPTIONS="-u $FCGI_USER -g $FCGI_GROUP -s $FCGI_SOCKET -S $FCGI_EXTRA_OPTIONS -F 1 -P /var/run/spawn-fcgi2.pid -- $FCGI_PROGRAM" =====Nginx 設定檔配置=====

#vim /usr/local/nginx/conf/nginx.conf
server {
        ~略~
        location /cgi-bin/ {
            gzip           off;
            root           /usr/local/nginx/html;
            fastcgi_pass   unix:/var/run/fcgiwrap.socket;
            include        fastcgi_params;
            fastcgi_index  index.cgi;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        }
        ~略~
}


#mkdir -p /usr/local/nginx/html/cgi-bin/
#cd /usr/local/nginx/html/cgi-bin/
#vim index.cgi

~內容~
#!/usr/bin/perl -w
     # Tell perl to send a html header.
     # So your browser gets the output
     # rather then (command line
     # on the server.)
print "Content-type: text/html\n\n";

     # print your basic html tags.
     # and the content of them.
print "Hello World!! \n";
print "Hello world\n";

#chown -R nginx:nginx /usr/local/nginx/html/cgi-bin/
#chmod -R 755 /usr/local/nginx/html/cgi-bin/

=====啟動或重啟 Nginx及Spawn-fcgi 並測試cgi網頁=====

#/usr/local/nginx/sbin/nginx -t -->測試設定檔語法OK
#/usr/local/nginx/sbin/nginx -s reload

#/etc/init.d/spawn-fcgi start #links http://your IP/cgi-bin/ ======在cgi上使用其他程式====== 以上步驟都焦點在Perl在CGI上，現在換一個php互動網頁程式來玩玩看。安裝及配置與以上的步驟都大致相同。 =====安裝套件===== 與以上套件一樣。只另外加裝php相關套件 * php-common * php-cli * php =====spawn-fcgi設定檔配置=====

#vim /etc/sysconfig/spawn-fcgi

SOCKET=/var/run/php-cgi.socket
OPTIONS="-u nginx -g nginx -s $SOCKET -S -M 0600 -C 32 -F 1 -P /var/run/spawn-fcgi.pid -- /usr/bin/php-cgi"

=====Nginx 設定檔配置===== #vim /usr/local/nginx/conf/nginx.conf server { ~略~ location ~ \.php$ { root /usr/local/nginx/html; fastcgi_pass unix:/var/run/php-cgi.socket; include fastcgi_params; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; } ~略~ }

#cd /usr/local/nginx/html/
#vim index.php

#chown nginx:nginx index.php && chmod 755 index.php 之後，再仿照前一節步驟啟動或重啟 Nginx及Spawn-fcgi 並測試php網頁即可。 ======參考資料====== - [[http://www.howtoforge.com/serving-cgi-scripts-with-nginx-on-centos-6.0-p2|Serving CGI Scripts With Nginx On CentOS 6.0]] - [[http://nginx.localdomain.pl/wiki/FcgiWrap|Simple CGI support for Nginx (fcgiwrap)]]
