Ubuntu 17.10 SugarCRM Professional 7.9 install

I'm basing this on an Ubuntu 17.10 install.

Base system only, no additional peripherals. Install SSH server components on install.

Let the installer set up a non-privileged user for you.

Network configuration is in /etc/network/interfaces. Your install will set this up based on your selections.

apt-get install lsof vim screen nmap links lynx sudo curl wget zsh unzip zip snmp mlocate traceroute man pciutils rsync tshark ntpdate ntp telnet bsd-mailx

/etc/cron.daily/mlocate.cron                         # build the locate database in advance of needing it

The default firewall in Ubuntu is ufw which is their generic netfilter firewall:

ufw allow 22/tcp

ufw allow 443/tcp

ufw enable

You can check the functioning of this via ufw status. Enabling the firewall will warn you that SSH connections might get disrupted - I had no disruption running the commands above.

Firewall-aside, I hate network ports being listened on that I'm in control of. lsof -i -n will show you LLMNR listening which you can disable by editing /etc/systemd/resolved.conf , setting LLMNR=0 and then systemctl restart systemd-resolved.service

At this point you have a relatively clean install of Ubuntu.

Now for SugarCRM prerequisites:

apt-get install mariadb-client mariadb-server postfix

systemctl enable mariadb.service

apt-get install apache2

a2enmod ssl

# Edit /etc/apache2/ports.conf and comment out "Listen 80"

systemctl restart apache2

apt-get install phpmyadmin 

# Let it reconfigure apache2

/usr/bin/mysql -e "GRANT ALL ON *.* TO 'adminuser'@'localhost' IDENTIFIED BY 'SOME_RANDOM_PASSWORD' WITH GRANT OPTION"

# Set up an admin user within MySQL

apt-get install php-imap

For SugarCRM install, see http://support.sugarcrm.com/Documentation/Sugar_Versions/7.9/Pro/Installation_and_Upgrade_Guide/:

apt-get install elasticsearch

apt-get install php-bcmath php-libsodium php-memcached

apt-get install memcached

Edit both /etc/php/7.1/{cli,apache2}/php.ini . I had to change the following to conform to the SugarCRM instructions:

• • date.timezone

  • max_execution_time

  • max_input_time

  • memory_limit

  • post_max_size

  • session.cookie_httponly

  • session.cookie_lifetime

  • session.gc_maxlifetime

  • session.save_handler

  • upload_max_filesize

The install instructions don't touch on it but if you're using memcached then you need to adjust session.save_path = "localhost:11211"

Frustratingly, Ubuntu 17.10 (as of 2017-12-06) distributes a broken copy of elasticsearch as per https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=829078 . It appears to be an upstream issue but still frustrating. So you need to follow https://www.elastic.co/guide/en/elasticsearch/reference/current/deb.html#deb-repo :

wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | apt-key add -

apt-get install apt-transport-https

echo "deb https://artifacts.elastic.co/packages/6.x/apt stable main" | tee -a /etc/apt/sources.list.d/elastic-6.x.list

apt-get install elasticsearch

Within /etc/elasticsearch/elasticsearch.yml I only set the following:

• • cluster.name

  • node.name

  • path.data

  • path.logs

  • bootstrap.memory_lock

  • network.host
