Installing TimeTrex on CentOS Linux v8 from the .ZIP File
This guide walks you through the process of installing TimeTrex on a CentOS Linux v8 machine using the .ZIP file. Please follow each step carefully to ensure successful installation.
Installation Steps
Step 1:
- Install the prerequisite packages:
dnf -y install http://rpms.remirepo.net/enterprise/remi-release-8.rpm epel-release
dnf config-manager --set-enabled remi
dnf -y module install php:remi-8.1
dnf -y install php-cli php-pgsql php-pspell php-gd php-gettext php-imap php-intl php-json php-soap php-zip php-curl php-ldap php-xml php-xsl php-mbstring php-bcmath php-process httpd postgresql-server unzip nano policycoreutils-python-utils
Step 2:
- Enable Apache to start on boot then restart the service:
systemctl enable httpd
service httpd restart
Step 3:
- Open the firewall to allow HTTP/HTTPS connections from the public zone:
firewall-cmd --permanent --zone=public --add-port=80/tcp
firewall-cmd --permanent --zone=public --add-port=443/tcp
firewall-cmd --reload
Step 4:
- Download the TimeTrex .ZIP file to your computer.
Step 5:
- Unzip the TimeTrex .ZIP file to the root web directory:
unzip <TimeTrex-installer>.zip -d /var/www/html/
- Rename the unzipped directory:
mv /var/www/html/TimeTrex_v<version>/ /var/www/html/timetrex
Step 6:
- Rename the TimeTrex.ini.php file:
mv /var/www/html/timetrex/timetrex.ini.php-example_linux /var/www/html/timetrex/timetrex.ini.php
Step 7:
- Edit the timetrex.ini.php and confirm all paths are correct:
nano /var/www/html/timetrex/timetrex.ini.php
- Note: Make sure the log directory and storage paths are created and that Apache can write to them.
- If you are using the default directories you can use these commands:
mkdir -p /var/timetrex/storage
mkdir -p /var/log/timetrex
chgrp -R apache /var/timetrex
chmod 775 -R /var/timetrex
chgrp -R apache /var/log/timetrex
chmod 775 -R /var/log/timetrex
chgrp apache -R /var/www/html/timetrex
chmod 775 -R /var/www/html/timetrex
- Configure SELinux so access to the above directories is allowed:
semanage fcontext -a -t httpd_sys_rw_content_t "/var/www/html/timetrex(/.*)?"
semanage fcontext -a -t httpd_sys_rw_content_t "/var/timetrex(/.*)?"
semanage fcontext -a -t httpd_sys_rw_content_t "/var/log/timetrex(/.*)?"
restorecon -r "/var"
setsebool -P httpd_can_network_connect 1
setsebool -P httpd_can_sendmail 1
Step 8:
- Create a user and database for TimeTrex to use:
postgresql-setup initdb
systemctl start postgresql
systemctl enable postgresql
su postgres
psql
CREATE USER timetrex WITH CREATEDB CREATEROLE LOGIN PASSWORD 'passwordhere';
CREATE DATABASE timetrex;
\q
exit
- Once you have made the database and user we need to set the authentication for connections to md5. We do this sowe can log in with the password we set for the timetrex user:
nano /var/lib/pgsql/data/pg_hba.conf
- Change the end of the following line:
"local all all peer"
- To this instead:
"local all all md5"
- Then restart postgres to load the new configuration:
systemctl restart postgresql
Step 9:
- Point your web browser to the TimeTrex web-based installer:
http://<web server address>/<timetrex directory>/interface/install/install.php
- ie: http://www.my-company.com/timetrex/interface/install/install.php
Step 10:
- Follow the on screen instructions that will walk you through the installation wizard.
- *NOTE: On the "DatabaseConfiguration" step you will need to enter the above created password for the database in the "Database Password"field. As well you will need to set the "Host Name" field to be two single quotes ('') so unix socket connections are used.
Thank you for choosing TimeTrex. We look forward to being part of your operational excellence.
