This tutorial exhibits the set up of an Ubuntu 18.04 (Bionic Beaver) hosting server with Apache 2.4, Postfix, Dovecot, Bind and PureFTPD to organize it for the set up of ISPConfig 3.1. The ensuing system will present a Web, Mail, Mailinglist, DNS and FTP Server.

ISPConfig is a hosting management panel that means that you can configure the next providers via an online browser: Apache or Nginx net server, Postfix mail server, Courier or Dovecot IMAP/POP3 server, MySQL, BIND or MyDNS nameserver, PureFTPd, SpamAssassin, ClamAV, and plenty of extra. This setup covers the set up of Apache (as an alternative of Nginx), BIND (as an alternative of MyDNS), and Dovecot (as an alternative of Courier).

1. Preliminary Be aware

On this tutorial, I exploit the hostname server1.instance.com with the IP tackle 192.168.1.100 and the gateway 192.168.1.1  These settings may differ for you, so you must substitute them the place applicable.  Earlier than continuing additional you might want to have a primary minimal set up of Ubuntu 18.04 as defined within the tutorial.

The instructions on this tutorial need to be run with root permissions. To keep away from including sudo in entrance of every command, you will need to change into root consumer by working:

sudo -s

earlier than you proceed.

2. Edit /and so on/apt/sources.listing And Replace Your Linux Set up

Edit /and so on/apt/sources.listing. Remark out or take away the set up CD from the file and be sure that the universe and multiverse repositories are enabled. It ought to appear like this afterwards:

nano /and so on/apt/sources.listing

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

Then run

apt-get replace

to replace the apt bundle database and

apt-get improve

to put in the newest updates (if there are any). When you see {that a} new kernel will get put in as a part of the updates, it’s best to reboot the system afterwards:

reboot

 

3. Change the Default Shell

/bin/sh is a symlink to /bin/sprint, nonetheless we’d like /bin/bash, not /bin/sprint. Subsequently, we do that:

dpkg-reconfigure sprint

Use sprint because the default system shell (/bin/sh)? <– No

When you do not do that, the ISPConfig set up will fail.

4. Disable AppArmor

AppArmor is a safety extension (much like SELinux) that ought to present prolonged safety. For my part, you do not want it to configure a safe system, and it often causes extra issues than benefits (consider it after you could have executed every week of trouble-shooting as a result of some service wasn’t working as anticipated, and you then discover out that all the pieces was okay, solely AppArmor was inflicting the issue). Subsequently, I disable it (this can be a should if you wish to set up ISPConfig afterward).

We are able to disable it like this:

service apparmor cease
update-rc.d -f apparmor take away
apt-get take away apparmor apparmor-utils

5. Synchronize the System Clock

It’s a good suggestion to synchronize the system clock with an NTP (network time protocol) server over the Web while you run a bodily server. In case you run a digital server then it’s best to skip this step. Simply run

apt-get -y set up ntp

and your system time will all the time be in sync.

6. Set up Postfix, Dovecot, MariaDB, rkhunter, and binutils

For putting in postfix, we have to be certain that sendmail will not be put in and working. To cease and take away sendmail run this command:

service sendmail cease; update-rc.d -f sendmail take away

The error message:

Didn’t cease sendmail.service: Unit sendmail.service not loaded.

Is okay, it simply implies that sendmail was not put in, so there was nothing to be eliminated.

Now we are able to set up Postfix, Dovecot, MariaDB (as MySQL substitute), rkhunter, and binutils with a single command:

apt-get -y set up postfix postfix-mysql postfix-doc mariadb-client mariadb-server openssl getmail4 rkhunter binutils dovecot-imapd dovecot-pop3d dovecot-mysql dovecot-sieve dovecot-lmtpd sudo

You’ll be requested the next questions:

Normal sort of mail configuration: <– Web Website
System mail title: <– server1.instance.com

It can be crucial that you simply use a subdomain as “system mail name” like server1.instance.com or server1.yourdomain.com and never a website that you simply wish to use as e-mail area (e.g. yourdomain.tld) later.

Subsequent, open the TLS/SSL and submission ports in Postfix:

nano /and so on/postfix/grasp.cf

Uncomment the submission and smtps sections as follows – add the road -o smtpd_client_restrictions=permit_sasl_authenticated,reject to each sections and depart all the pieces thereafter commented:

[...]
 submission inet n       -       y       -       -       smtpd
   -o syslog_name=postfix/submission
   -o smtpd_tls_security_level=encrypt
   -o smtpd_sasl_auth_enable=sure
   -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=$mua_sender_restrictions
 #  -o smtpd_recipient_restrictions=permit_sasl_authenticated,reject
 #  -o milter_macro_daemon_name=ORIGINATING
 smtps     inet  n       -       y       -       -       smtpd
   -o syslog_name=postfix/smtps
   -o smtpd_tls_wrappermode=sure
   -o smtpd_sasl_auth_enable=sure
   -o smtpd_client_restrictions=permit_sasl_authenticated,reject
 #  -o smtpd_reject_unlisted_recipient=no
 #  -o smtpd_client_restrictions=$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
 [...]

NOTE: The whitespaces in entrance of the “-o …. ” strains are essential!

Restart Postfix afterward:

service postfix restart

We wish MySQL to pay attention on all interfaces, not simply localhost. Subsequently, we edit /and so on/mysql/mariadb.conf.d/50-server.cnf and remark out the road bind-address = 127.0.0.1:

nano /and so on/mysql/mariadb.conf.d/50-server.cnf

[...]
 # As a substitute of skip-networking the default is now to pay attention solely on
 # localhost which is extra suitable and isn't much less safe.
 #bind-address           = 127.0.0.1

[...]

Now we set a root password in MariaDB. Run:

mysql_secure_installation

You’ll be requested these questions:

Enter present password for root (enter for none): <– press enter
Set root password? [Y/n] <– y
New password: <– Enter the brand new MariaDB root password right here
Re-enter new password: <– Repeat the password
Take away nameless customers? [Y/n] <– y
Disallow root login remotely? [Y/n] <– y
Reload privilege tables now? [Y/n] <– y

Set the password authentication methodology in MariaDB to native so we are able to use PHPMyAdmin later to attach as root consumer:

echo “update mysql.user set plugin = ‘mysql_native_password’ where user=’root’;” | mysql -u root

Edit the file /and so on/mysql/debian.cnf and set the MYSQL / MariaDB root password there twice within the rows that begin with password.

nano /and so on/mysql/debian.cnf

The MySQL root password that must be added is proven in learn, on this instance the password is “howtoforge”.

# Robotically generated for Debian scripts. DO NOT TOUCH!
[client]
host = localhost
consumer = root
password = howtoforge
socket = /var/run/mysqld/mysqld.sock
[mysql_upgrade]
host = localhost
consumer = root
password = howtoforge
socket = /var/run/mysqld/mysqld.sock
basedir = /usr

Then we restart MariaDB:

service mysql restart

Now test that networking is enabled. Run

netstat -tap | grep mysql

The output ought to appear like this:

[email protected]:~# netstat -tap | grep mysql
tcp6 Zero 0 [::]:mysql [::]:* LISTEN 30591/mysqld
[email protected]:~#

7. Set up Amavisd-new, SpamAssassin, and Clamav

To put in amavisd-new, SpamAssassin, and ClamAV, we run

apt-get -y set up 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

The ISPConfig Three setup makes use of amavisd which hundreds the SpamAssassin filter library internally, so we are able to cease SpamAssassin to release some RAM:

service spamassassin cease
update-rc.d -f spamassassin take away

To start out ClamAV use:

freshclam
service clamav-daemon begin

The next error may be ignored on the primary run of freshclam.

ERROR: /var/log/clamav/freshclam.log is locked by one other course of
ERROR: Downside with inner logger (UpdateLogFile = /var/log/clamav/freshclam.log).

The amavisd-new program has presently a bug in Ubuntu 18.04 which prevents that emails get signed with Dkim accurately. Run the next instructions to patch 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
cp -pf amavisd-new amavisd-new_bak
patch < /tmp/ubuntu-amavisd-new-2.11.patch

In case you get an error for thelast ‘patch’ command, then Ubuntu has most likely fastened the difficulty within the meantime, so it needs to be protected to disregard that error then.

7.1 Set up Metronome XMPP Server (non-obligatory)

The Metronome XMPP Server offers an XMPP chat server. This step is non-obligatory, if you don’t want a chat server, then you’ll be able to skip this step. No different ISPConfig capabilities depend upon this software program.

Set up the next packages with apt.

apt-get -y set up git lua5.1 liblua5.1-0-dev lua-filesystem libidn11-dev libssl-dev lua-zlib lua-expat lua-event lua-bitop lua-socket lua-sec luarocks luarocks

luarocks set up lpc

Add a shell consumer for Metronome.

adduser –no-create-home –disabled-login –gecos ‘Metronome’ metronome

Obtain Metronome to the /decide listing and compile it.

cd /decide; git clone https://github.com/maranda/metronome.git metronome
cd ./metronome; ./configure –ostype=debian –prefix=/usr
make
make set up

Metronome has now be put in to /decide/metronome.
