1. Install Web server Apache

1.1Install apache2 ( httpd-2.4.43 )

# zypper -n install apache2

1.2 Apache2 : Basic Configuration

# vi /etc/sysconfig/apache2
# Line 152: Change to administrator address.
APACHE_SERVERADMIN=<administrator E-mail>
# Line 169: Change to own domain name
APACHE_SERVERNAME=”korodes.com”
# Line 248: Change
APACHE_SERVERTOKENS=”Prod”

# vi /etc/apache2/httpd.conf
# Line 197: Set file names that can be accessed only by directory name
DirectoryIndex index.html index.htm index.php

# 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 Enable Firewalld

The HTTP service must be allowed. Note that HTTP uses 80/TCP; HTTPS uses 443.

# 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 verify that it works.
Start a web browser on the client PC and access the test page you created as follows

# 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 the following message is displayed.

2. Apache2 : Use Perl scripts.

Configure Perl scripts to be used as CGI

2.1 Install Perl

①Install

# zypper -n install perl

②Enable the CGI module.

# a2enmod cgid

CGI execution is allowed under [/srv/www/cgi-bin/] by default.
よって、For example, by creating and deploying the script [/srv/www/cgi-bin/index.cgi], you can access [http://(httpd server)/cgi-bin/index.cgi] Because this setting treats all files under [/srv/www/cgi-bin/] as CGI, non-CGI files cannot be displayed.
#The following configuration will allow CGI execution under /srv/www/cgi-bin/.

# grep -n “^ *ScriptAlias” /etc/apache2/default-server.conf
72:ScriptAlias /cgi-bin/ “/srv/www/cgi-bin/”

# systemctl restart apache2

③Create a test script and check it works.

# cat > /srv/www/cgi-bin/test_script <<‘EOF’
#!/usr/bin/perl
print “Content-type: text/html\n\n”;
print “Hello CGI\n”;
EOF

Grant permissions to script files.

# chmod 705 /srv/www/cgi-bin/test_script

operation check

# curl http://localhost/cgi-bin/test_script
Hello CGI

If you see the message “Hello CGI”, it is normal.

3. Apache2 : Virtual Host Configuration

Configure both domains sample1.korodes.com sample2.korodes.com to be displayed on a single server

# cd /srv/www/htdocs/
Create a directory named sample1.korodes.com under /srv/www/htdocs/.
# mkdir sample1.korodes.com
Create an idex.html file in the sample1.korodes.com directory
# vi sample1.korodes.com/index.html
+++++++++Virtual Host Site1 sample1.korodes.com ++++++++++

Create a new virtual_host.conf file under /etc/apache2/vhosts.d

Edit the hosts file

#vi /etc/hosts
# hosts         This file describes a number of hostname-to-address
#               mappings for the TCP/IP subsystem. It is mostly
#               used at boot time, when no name servers are running.
#               On small systems, this file can be used instead of a
#               “named” name server.
# Syntax:
#
# IP-Address Full-Qualified-Hostname Short-Hostname
#
127.0.0.1       localhost
# special IPv6 addresses
::1             localhost ipv6-localhost ipv6-loopback
fe00::0         ipv6-localnet
ff00::0         ipv6-mcastprefix
ff02::1         ipv6-allnodes
ff02::2         ipv6-allrouters
ff02::3         ipv6-allhosts

192.168.11.11 sample1.korodes.com　　← Add

# systemctl restart apache2

Create a directory and index.html file for the domain “sample2.korodes.com” in the same way.

# cd /srv/www/htdocs
# mkdir sample2.korodes.com
# vi sample2.korodes.com/index.html
*************Virtual Host Site2 sample2.korodes.com *********

Add to virtual_host.conf file

# vi /etc/apache2/vhosts.d/virtual_host.conf
<VirtualHost *:80>
ServerName sample1.korodes.com
ServerAdmin <Administrator 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># Add the following
<VirtualHost *:80>
ServerName sample2.korodes.com
ServerAdmin <Administrator 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 the hosts file

# systemctl restart apache2

It is OK if “http://sample1.korodes.com” and “http://sample2.korodes.com” appear in your web browser as shown below.

4. Apache2 : Use PHP scripts

Install PHP and configure it so that PHP scripts can be used

4.1 Install PHP

# a2enmod php7
# vi /etc/php7/apache2/php.ini
# Line 962: Time zone setting
date.timezone = ‘Asia/Tokyo’

# systemctl restart apache2

4.2 Create a PHP test page and check it works.

Create a test page

# vi /srv/www/htdocs/sample1.korodes.com/test.php
<?php phpinfo(); ?>

# systemctl restart httpd.service

Start a Web browser on the client PC and access “http://sample1.korodes.com/test.php”. If the test page you created is displayed as shown below, you are good to go.
