Use Ruby Scripts
2017/07/25 |
Configure httpd to use Ruby as CGI scripts.
|
|
[1] | Install Ruby. |
[root@www ~]# dnf -y install ruby
|
[2] | By default, CGI is allowed under the [/var/www/cgi-bin] directory. It's possible to use Perl Scripts to put under the directory. All files under it is processed as CGI, though. |
# the settings below is the one for CGI [root@www ~]# grep -n "^ *ScriptAlias" /etc/httpd/conf/httpd.conf 247: ScriptAlias /cgi-bin/ "/var/www/cgi-bin/" |
[3] | If you'd like to allow CGI in other directories, configure like follows. For example, allow in [/var/www/html/cgi-enabled]. |
[root@www ~]#
vi /etc/httpd/conf.d/cgi-enabled.conf # create new # processes .rb as CGI scripts <Directory "/var/www/html/cgi-enabled"> Options +ExecCGI AddHandler cgi-script .rb </Directory> mkdir /var/www/html/cgi-enabled [root@www ~]# systemctl restart httpd |
[4] | If SELinux is enabled and also enable CGI except default location like above, add rules like follows. |
[root@www ~]#
[root@www ~]# dnf -y install checkpolicy policycoreutils-python-utils semanage fcontext -a -t httpd_sys_script_exec_t /var/www/html/cgi-enabled [root@www ~]# restorecon /var/www/html/cgi-enabled
|
[5] | Create a CGI test page and access to it from client PC with web browser. It's OK if following page is shown. |
[root@www ~]#
vi /var/www/html/cgi-enabled/index.rb #!/usr/bin/ruby print "Content-type: text/html\n\n" print "<html>\n<body>\n" print "<div style=\"width: 100%; font-size: 40px; font-weight: bold; text-align: center;\">\n" print "Ruby Script Test Page" print "\n</div>\n" print "</body>\n</html>\n" chmod 705 /var/www/html/cgi-enabled/index.rb |
