SerwerWeb.pl

In today's tutorial I will describe the process of preparing a fully functioning web server along with free panel for managing the ISPConfig.
Guidance has been prepared under the latest version of Ubuntu 18.04

For starters make changes in the system hostname. This step was describing in this guide.

We log on as root command:

sudo -s

I enter the password. Then install our favorite text file editor, for example, nano:

apt-get install nano

The next step is to set repositories in /etc/apt/sources.list

we command them:

nano /etc/apt/sources.list

The file should look like this:

#

# deb cdrom:[Ubuntu-Server 18.04 LTS _Bionic Beaver_ - Release amd64 (20180425.1)]/ bionic main restricted

#deb cdrom:[Ubuntu-Server 18.04 LTS _Bionic Beaver_ - Release amd64 (20180425.1)]/ bionic main restricted

# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to
# newer versions of the distribution.

# deb-src http://de.archive.ubuntu.com/ubuntu/ bionic main restricted

## Major bug fix updates produced after the final release of the
## distribution.

## Uncomment the following two lines to add software from Canonical's
## 'partner' repository.

# deb-src http://security.ubuntu.com/ubuntu bionic-security universe
deb http://security.ubuntu.com/ubuntu bionic-security multiverse
# deb-src http://security.ubuntu.com/ubuntu bionic-security multiverse

Then we make an update repositories and system updates:

apt-get update
apt-get upgrade

To be sure proper operation of the system and save all the changes make the system reboot command:

reboot

After the restart, re-log in to the root account on the system and make changes in the system shell.
We can make this command:

dpkg-reconfigure dash

The Communication select the option that is not well:

Use dash as the default system shell (/bin/sh)? 
Turn off AppArmor
 
AppArmor is a security extension (Similar to SELinux), which should provide enhanced security. check, is installed, and, if necessary, remove it. I do not think we need it to set up a secure system and usually causes more problems than benefits.
 
Deactivation will be done by issuing the command:
 
service apparmor stop
update-rc.d -f apparmor remove
apt-get remove apparmor apparmor-utils
 
We synchronize the time on a server with the NTP server
 
apt-get -y install ntp ntpdate
 
Install Postfix, Dovecot, MariaDB, phpMyAdmin, rkhunter, Binutils
 
Minor point here to install the necessary posfixa uninstall sendmail. We can make this command:
 
service sendmail stop; update-rc.d -f sendmail remove
 
Then install all packages:
 
apt-get -y install postfix postfix-mysql postfix-doc mariadb-client mariadb-server openssl getmail4 rkhunter binutils dovecot-imapd dovecot-pop3d dovecot-mysql dovecot-sieve dovecot-lmtpd sudo
 
The installer will ask you for an 2 options you select as below:
 
General type of mail configuration: 
Run TLS / SSL postfix
 
edit file:
 
nano /etc/postfix/master.cf
 
And since we comment section smtpd_client_restrictions=permit_sasl_authenticated,reject 
 
The whole should look like this:
 
[...]
submission inet n       -       -       -       -       smtpd
  -o syslog_name=postfix/submission
  -o smtpd_tls_security_level=encrypt
  -o smtpd_sasl_auth_enable=yes
  -o smtpd_client_restrictions=permit_sasl_authenticated,reject
#  -o smtpd_reject_unlisted_recipient=no
#  -o smtpd_client_restrictions=$mua_client_restrictions
#  -o smtpd_helo_restrictions=$mua_helo_restrictions
#  -o smtpd_sender_restrictions=$mua_sender_restrictions
#  -o smtpd_recipient_restrictions=permit_sasl_authenticated,reject
#  -o milter_macro_daemon_name=ORIGINATING
smtps     inet  n       -       -       -       -       smtpd
  -o syslog_name=postfix/smtps
  -o smtpd_tls_wrappermode=yes
  -o smtpd_sasl_auth_enable=yes
  -o smtpd_client_restrictions=permit_sasl_authenticated,reject
#  -o smtpd_reject_unlisted_recipient=no
#  -o smtpd_client_restrictions=$mua_client_restrictions
#  -o smtpd_helo_restrictions=$mua_helo_restrictions
#  -o smtpd_sender_restrictions=$mua_sender_restrictions
#  -o smtpd_recipient_restrictions=permit_sasl_authenticated,reject
#  -o milter_macro_daemon_name=ORIGINATING
[...]
 
After making changes to make to restart posfixa
 
service postfix restart
 
We want to, aby MariaDB / MySQL is not only on localhost. Therefore we edit the file /etc/mysql/mariadb.conf.d/50-server.cnf (for MariaDB or /etc/mysql/my.cnf (for MySQL) and comment out the line bind-address = 127.0.0.1:
 
nano /etc/mysql/mariadb.conf.d/50-server.cnf
 
We add # przy bind-address
 
[...]
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
#bind-address           = 127.0.0.1
[...]
 
Set the root password mysql server and pass the basic configuration with the command:
 
mysql_secure_installation
 
We answer questions like:
 
Enter current password for root (enter for none): 
We set the password authentication method for native, so that we can later PHPMyAdmin to connect as the root user:
 
echo "update mysql.user set plugin = 'mysql_native_password' where user='root';" | mysql -u root
 
File Modification /etc/mysql/debian.cnf and set the root password
 
nano /etc/mysql/debian.cnf
 
Below the modified file looks like this:
 
# Automatically generated for Debian scripts. DO NOT TOUCH!
[client]
host = localhost
user = root
password = HASLO ROOT
socket = /var/run/mysqld/mysqld.sock
[mysql_upgrade]
host = localhost
user = root
password = HASLO ROOT
socket = /var/run/mysqld/mysqld.sock
basedir = /usr
 
Edit your /etc/mysql/my.cnf and monitoring local MySQL Hashing
 
nano /etc/mysql/my.cnf
 
The file should look like this:
 
[...]
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
#bind-address           = 127.0.0.1
[...]
 
We make a server restart mysql command:
 
service mysql restart
 
Installation Amavisd-new, SpamAssassin, And ClamAV
 
apt-get -y install amavisd-new spamassassin clamav clamav-daemon unzip bzip2 arj nomarch lzop cabextract apt-listchanges libnet-ldap-perl libauthen-sasl-perl clamav-docs daemon libio-string-perl libio-socket-ssl-perl libnet-ident-perl zip libnet-dns-perl postgrey
 
To update antivirus signatures ClamAV and start the clamd spend the following commands:
 
freshclam
service clamav-daemon start
 
Virus database update can take a while, please be patient to wait.
 
You can ignore the following error when you first start freshclam.
 
ERROR: /var/log/clamav/freshclam.log is locked by another process
ERROR: Problem with internal logger (UpdateLogFile = /var/log/clamav/freshclam.log).
 
Amavisd-new program now contains an error in Ubuntu 18.04, which prevents proper signing e-mails with DKIM. Run the following command, to attach amavisd-new.
 
cd /tmp
wget https://git.ispconfig.org/ispconfig/ispconfig3/raw/stable-3.1/helper_scripts/ubuntu-amavisd-new-2.11.patch
cd /usr/sbin

Following will be a few questions for primary configuration so be careful.
Default values are in [brackets] and can be accepted with .
Tap in "quit" (without the quotes) to stop the installer.


Select language (in,de) [in]: 
Finished script has been installed and is available at https://ipserwera:8080
 
The default data to the panel admin login password is admin
 
In this way we have a fully operational and configured web server once the mail server databases and ftp.
