# systemctl start apache2 # systemctl enable apache2 Created symlink /etc/systemd/system/httpd.service → /usr/lib/systemd/system/apache2.service. Created symlink /etc/systemd/system/apache.service → /usr/lib/systemd/system/apache2.service. Created symlink /etc/systemd/system/multi-user.target.wants/apache2.service → /usr/lib/systemd/system/apache2.service. |
1.3 Firewalld
HTTP service permission is required. Note that HTTP uses 80/TCP; HTTPS uses 443
|
1 2 3 4 5 6 |
# firewall-cmd --add-service=http --permanent Success # firewall-cmd --add-service=https --permanent Success # firewall-cmd --reload success |
1.4 Apache2 : operation check
Create an HTML test page to check the operation. Start a Web browser on the client PC and check if the test page you created can be accessed as follows
|
1 2 3 4 5 6 7 8 9 |
# vi /srv/www/htdocs/index.html <html> <body> <div style="width: 100%; font-size: 40px; font-weight: bold; text-align: center;"> Test Page </div> </body> </html> |
Access http://<IP address> with a browser and confirm that it is displayed as shown below.
2. Apache2 : Using Perl Scripts
Configure Perl scripts to be used as CGI
2.1 Perl
①Install
|
1 |
# zypper -n install perl |
②Enable CGI module
|
1 |
# a2enmod cgid |
CGI execution is permitted by default under [/srv/www/cgi-bin/].
For example, by creating and placing the script [/srv/www/cgi-bin/index.cgi], you can access [http://(httpd server)/cgi-bin/index.cgi].
This configuration treats all files under [/srv/www/cgi-bin/] as CGI, so files other than CGI cannot be displayed.
|
1 2 |
# grep -n "^ *ScriptAlias" /etc/apache2/default-server.conf 72:ScriptAlias /cgi-bin/ "/srv/www/cgi-bin/" |
|
1 |
# systemctl restart apache2 |
③Create test scripts and check operation
|
1 2 3 4 5 |
# cat > /srv/www/cgi-bin/test_script <<'EOF' #!/usr/bin/perl print "Content-type: text/html\n\n"; print "Hello CGI\n"; EOF |
Authorize script files
|
1 |
# chmod 705 /srv/www/cgi-bin/test_script |
operation check
|
1 2 |
# curl http://localhost/cgi-bin/test_script Hello CGI |
If "Hello CGI" is displayed, it is normal.
3. Apache2 : Virtual Host Settings
Configure both domains sample1.korodes.com sample2.korodes.com to be displayed on one server
|
1 |
# cd /srv/www/htdocs/ |
Create a directory named sample1.korodes.com under /srv/www/htdocs/
|
1 |
# mkdir sample1.korodes.com |
Create the idex.html file in the sample1.korodes.com directory
|
1 2 3 |
# vi sample1.korodes.com/index.html +++++++++Virtual Host Site1 sample1.korodes.com ++++++++++ |
Create a new virtual_host.conf under /etc/apache2/vhosts.d
|
1 2 3 4 5 6 7 8 9 10 |
# vi /etc/apache2/vhosts.d/virtual_host.conf <VirtualHost *:80> ServerName sample1.korodes.com ServerAdmin Create a new virtual_host.conf under /etc/apache2/vhosts.d DocumentRoot /srv/www/htdocs/sample1.korodes.com ErrorLog /var/log/apache2/sample1.korodes.com.error.log CustomLog /var/log/apache2/sample1.korodes.com.access.log combined LogLevel warn </VirtualHost> |
Edit hosts file(Example. : server IP address : 192.168.11.83)

#vi /etc/hosts # # hosts This file describes a number of hostname-to-address # mappings for the TCP/IP subsystem.

# systemctl restart apache2 |
Similarly, create a directory and index.html file for the domain "sample2.korodes.com"
|
1 2 |
# cd /srv/www/htdocs # mkdir sample2.korodes.com |
|
1 2 3 |
# vi sample2.korodes.com/index.html *************Virtual Host Site2 sample2.korodes.com ********* |
Add to virtual_host.conf file
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
# vi /etc/apache2/vhosts.d/virtual_host.conf <VirtualHost *:80> ServerName sample1.korodes.com ServerAdmin <Administrator's email address> DocumentRoot /srv/www/htdocs/sample1.korodes.com ErrorLog /var/log/apache2/sample1.korodes.com.error.log CustomLog /var/log/apache2/sample1.korodes.com.access.log combined LogLevel warn </VirtualHost> <VirtualHost *:80> ServerName sample2.korodes.com ServerAdmin <Administrator's email address> DocumentRoot /srv/www/htdocs/sample2.korodes.com ErrorLog /var/log/apache2/sample2.korodes.com.error.log CustomLog /var/log/apache2/sample2.korodes.com.access.log combined LogLevel warn </VirtualHost> |
Add to hosts file

|
1 |
# systemctl restart apache2 |
It is OK if "http://sample1.korodes.com" and "http://sample2.korodes.com" are displayed in the web browser as shown below.
4. Apache2 : Using PHP Scripts
Install and configure PHP so that PHP scripts are available
4.1 PHP Install
|
1 2 |
# zypper -n install php8 php8-pear php8-mbstring apache2-mod_php8 # a2enmod php8 |

1 2 3 4 |
# vi /etc/php8/apache2/php.ini # Line 974：Time Zone Setting date.timezone = 'Asia/Tokyo' |
|
1 |
# systemctl restart apache2 |
4.2 Create a PHP test page and check its operation
Create test page
|

# vi /srv/www/htdocs/sample1.korodes.com/test.php <?php phpinfo(); ?> |
|
1 |
# systemctl restart httpd.service |
Start a Web browser on the client PC, access "http://sample1.korodes.com/test.php", and if the test page you created is displayed as shown below, it is OK.
