Install TACTIC on CentOS 7

Updated December 2019

These instructions are for a TACTIC server that will use PostgreSQL and Apache on a Cent OS server. Refer to the General TACTIC Installation for other OSes. For other database types, refer to guides in Install TACTIC Application.

Install PostgreSQL

CentOS 7 comes with PostgreSQL 9.2 by default. TACTIC needs PostgreSQL 9.4 and higher.

Here are instructions to install PostgreSQL 11 using official PostgreSQL packages.

rpm -Uvh
yum update
yum install postgresql11-server postgresql11-contrib postgresql11-devel
/usr/pgsql-11/bin/postgresql-11-setup initdb

Starting PostgreSQL and enabling the service

systemctl start postgresql-11
systemctl enable postgresql-11


Enable Extra Packages for Enterprise Linux (EPEL).

yum --enablerepo=extras install epel-release

Install Python 3 and supporting modules

Check if Python 3 is already installed on your system by running the following shell command and reviewing the Python 3 console:

[tactic@localhost ~]$ python3
Python 3.6.8 (default, Aug  7 2019, 17:28:10)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-39)] on linux
Type "help", "copyright", "credits" or "license" for more information.

Python 3.7 is recommended for TACTIC 4.7. If Python 3.7 is not available, Python 3.6 can be used instead.

Install Python 3 using yum:

yum install python3

In CentOS 7, the above command will install Python 3.6 by default. We will need to install Python 3 supporting modules. In CentOS 7, the modules are python36-xxx instread of python3-xxx.

yum install python36-pycryptodomex python36-lxml python36-requests python36-pytz

Alternatively you can also install these modules using pip.

pip3 install pycryptodomex
pip3 install lxml
pip3 install requests
pip3 install pytz

Install Python DB connectivity module.

  • PostgreSQL:

    yum install python3-psycopg2

Install ImageMagick

yum install ImageMagick ImageMagick-devel ImageMagick-perl

Install ffmpeg

rpm --import
rpm -Uvh
yum install ffmpeg

Install Apache

yum install httpd
firewall-cmd --add-service=http --permanent
firewall-cmd --reload
/usr/sbin/setsebool -P httpd_can_network_connect 1

Starting Apache and enabling the service for the startup

sudo systemctl start httpd
sudo systemctl enable httpd


Download the TACTIC RPM from community site downloads page.

rpm -Uhv <TACTIC-RPM-file>

Configure PostgreSQL

Note: TACTIC requires database access, and for ease of installation, we recommend using the PostgreSQL configuration file provided in the source code. After installation, you can further configure and secure your database.

Replace the file,




Restart PostgreSQL,

systemctl restart postgresql-11

Run TACTIC Bootstrap

sudo su - tactic
python3 /opt/tactic/tactic/src/pyasm/search/upgrade/postgresql/

Starting TACTIC service

sudo systemctl start tactic

Or run the server from the command line:

python3 /opt/tactic/tactic/src/bin/
