1. Install Web server Apache
1.1Install apache2 ( httpd-2.4.43 )
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”
# Line 197: Set file names that can be accessed only by directory name
DirectoryIndex index.html index.htm index.php
# 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
<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
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/”
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.
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
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
<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>
#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:

192.168.11.11 sample2.korodes.com ←Add
# 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
# 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
<?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.
