The Perfect Server - OpenSUSE 11.4 x86_64 [ISPConfig 3] - Page 5

10 Install The Apache 2 Webserver With PHP5, Ruby, WebDAV

Install Apache2 and suphp. Run:

yast2 -i apache2 apache2-mod_fcgid

Install PHP5:

yast2 -i php5-bcmath php5-bz2 php5-calendar php5-ctype php5-curl php5-dom php5-ftp php5-gd php5-gettext php5-gmp php5-iconv php5-imap php5-ldap php5-mbstring php5-mcrypt php5-mysql php5-odbc php5-openssl php5-pcntl php5-pgsql php5-posix php5-shmop php5-snmp php5-soap php5-sockets php5-sqlite php5-sysvsem php5-tokenizer php5-wddx php5-xmlrpc php5-xsl php5-zlib php5-exif php5-fastcgi php5-pear php5-sysvmsg php5-sysvshm ImageMagick curl apache2-mod_php5

zypper install http://download.opensuse.org/repositories/server:/php/openSUSE_11.4/x86_64/suphp-0.7.1-3.2.x86_64.rpm

Then run these commands to enable the Apache modules (including WebDAV):

a2enmod suexec
a2enmod rewrite
a2enmod ssl
a2enmod actions
a2enmod suphp
a2enmod fcgid
a2enmod dav
a2enmod dav_fs
a2enmod dav_lock
chown root:www /usr/sbin/suexec2
chmod 4755 /usr/sbin/suexec2

Next we build the mod_ruby Apache module (it is not available as an OpenSUSE 11.4 package, therefore we have to build it ourselves):

yast2 -i apache2-devel ruby ruby-devel

cd /tmp
wget http://modruby.net/archive/mod_ruby-1.3.0.tar.gz
tar zxvf mod_ruby-1.3.0.tar.gz
cd mod_ruby-1.3.0/
./configure.rb --with-apr-includes=/usr/include/apr-1
make
make install

a2enmod ruby

Start Apache:

chkconfig --add apache2
/etc/init.d/apache2 start

Install phpMyAdmin:

zypper install http://download.opensuse.org/repositories/server:/php:/applications/openSUSE_11.4/noarch/phpMyAdmin-3.3.9.2-3.1.noarch.rpm

11 Install PureFTPd

Install the pure-ftpd FTP daemon. Run:

yast2 -i pure-ftpd

chkconfig --add pure-ftpd
/etc/init.d/pure-ftpd start

Now we configure PureFTPd to allow FTP and TLS sessions. FTP is a very insecure protocol because all passwords and all data are transferred in clear text. By using TLS, the whole communication can be encrypted, thus making FTP much more secure.

OpenSSL is needed by TLS; to install OpenSSL, we simply run:

yast2 -i openssl

Open /etc/pure-ftpd/pure-ftpd.conf...

vi /etc/pure-ftpd/pure-ftpd.conf

If you want to allow FTP and TLS sessions, set TLS to 1:

[...]
# This option can accept three values :
# 0 : disable SSL/TLS encryption layer (default).
# 1 : accept both traditional and encrypted sessions.
# 2 : refuse connections that don't use SSL/TLS security mechanisms,
#     including anonymous sessions.
# Do _not_ uncomment this blindly. Be sure that :
# 1) Your server has been compiled with SSL/TLS support (--with-tls),
# 2) A valid certificate is in place,
# 3) Only compatible clients will log in.
TLS                      1
[...]

If you want to accept TLS sessions only (no FTP), set TLS to 2:

[...]
# This option can accept three values :
# 0 : disable SSL/TLS encryption layer (default).
# 1 : accept both traditional and encrypted sessions.
# 2 : refuse connections that don't use SSL/TLS security mechanisms,
#     including anonymous sessions.
# Do _not_ uncomment this blindly. Be sure that :
# 1) Your server has been compiled with SSL/TLS support (--with-tls),
# 2) A valid certificate is in place,
# 3) Only compatible clients will log in.
TLS                      2
[...]

To not allow TLS at all (only FTP), set TLS to 0:

[...]
# This option can accept three values :
# 0 : disable SSL/TLS encryption layer (default).
# 1 : accept both traditional and encrypted sessions.
# 2 : refuse connections that don't use SSL/TLS security mechanisms,
#     including anonymous sessions.
# Do _not_ uncomment this blindly. Be sure that :
# 1) Your server has been compiled with SSL/TLS support (--with-tls),
# 2) A valid certificate is in place,
# 3) Only compatible clients will log in.
TLS                      0
[...]

In order to use TLS, we must create an SSL certificate. I create it in /etc/ssl/private/, therefore I create that directory first:

mkdir -p /etc/ssl/private/

Afterwards, we can generate the SSL certificate as follows:

openssl req -x509 -nodes -days 7300 -newkey rsa:2048 -keyout /etc/ssl/private/pure-ftpd.pem -out /etc/ssl/private/pure-ftpd.pem

Country Name (2 letter code) [AU]: <-- Enter your Country Name (e.g., "DE").
State or Province Name (full name) [Some-State]: <-- Enter your State or Province Name.
Locality Name (eg, city) []: <-- Enter your City.
Organization Name (eg, company) [Internet Widgits Pty Ltd]: <-- Enter your Organization Name (e.g., the name of your company).
Organizational Unit Name (eg, section) []: <-- Enter your Organizational Unit Name (e.g. "IT Department").
Common Name (eg, YOUR name) []: <-- Enter the Fully Qualified Domain Name of the system (e.g. "server1.example.com").
Email Address []: <-- Enter your Email Address.

Change the permissions of the SSL certificate:

chmod 600 /etc/ssl/private/pure-ftpd.pem

Finally restart PureFTPd:

/etc/init.d/pure-ftpd restart

That's it. You can now try to connect using your FTP client; however, you should configure your FTP client to use TLS - see the next chapter how to do this with FileZilla.

12 Install BIND

The BIND nameserver can be installed as follows:

yast2 -i bind

Create the BIND system startup links and start it:

chkconfig --add named
/etc/init.d/named start

13 Install Webalizer And AWStats

Since ISPConfig 3 lets you choose if you want to use Webalizer or AWStats to create your web site statistics, we install both:

yast2 -i webalizer perl-DateManip

zypper install http://download.opensuse.org/repositories/network:/utilities/openSUSE_11.4/noarch/awstats-7.0-14.1.noarch.rpm

14 Install fail2ban

fail2ban can be installed as follows:

yast2 -i fail2ban

15 Install Jailkit

Jailkit can be installed like this:

zypper install http://download.opensuse.org/repositories/security/openSUSE_11.4/x86_64/jailkit-2.13-1.2.x86_64.rpm

16 Synchronize The System Clock

If you want to have the system clock synchronized with an NTP server do the following:

yast2 -i xntp

Then add system startup links for ntp and start ntp:

chkconfig --add ntp
/etc/init.d/ntp start
