Stack 205 provides detailed information about the database and application server configurations needed to correctly install the following versions of ProcessMaker on the platform CentOS/RHEL 7.2.
|ProcessMaker 3.1||ProcessMaker 3.2|
|ProcessMaker 3.1.1||ProcessMaker 3.2.1|
Stack 205 is supported by ProcessMaker, meaning that it has been tested by the Quality Control team.
|CentOS/RHEL 7.2||MySQL 5.5.x||5.6.x|
Assuming CentOS 7.2 Core or Desktop is already installed, please read the following instructions to have the stack ready to be configured before installing ProcessMaker.
Step 1: Disable MariaDB
MariaDB is a drop-in replacement for MySQL installed on CentOS 7.2 by default. It is necessary to uninstall MariaDB to avoid issues with MySQL, which is the default database system for ProcessMaker.
To uninstall MariaDB, open a terminal and enter the following command:
Step 2: Install Apache 2.4
mod_ssl is an Apache module that provides SSL v2/v3 and TLS v1 support for the Apache HTTP server necessary for ProcessMaker.
Run the following command to install Apache 2.4 and the SSL module:
Then, start the Apache service and set it to start automatically at boot.
Make sure the httpd service is running by checking its status with the following command:
The status of the httpd service should be "active (running)":
Step 3: Install PHP 5.6
CentOS 7 (and its EPEL repository) comes with PHP 5.4 by default. PHP 5.4 is no longer supported by ProcessMaker, so do not forget to add the following repository before installing PHP 5.6.
First, add the corresponding EPEL repository to download PHP.
Then, install PHP 5.6 along with all the following extensions that ProcessMaker needs to work properly.
To check if all the PHP modules were installed, run the following command:
The outcome will be similar to the following:
Step 4: Install MySQL 5.5.XX
|Warning: ProcessMaker is not compatible with MySQL STRICT mode, which is enabled by default as of MySQL 5.6.6. Read the Turning off MySQL STRICT Mode section to learn how to disable it.|
Download the latest bundle of MySQL-5.5.XX directly to the server from the official source: http://dev.mysql.com/downloads/mysql/5.5.html#downloads (choose Generics or Compatible EL version).
For instance, download the latest version of MySQL, which is currently MySQL 5.5.58:
Then, decompress the file:
Install the MySQL server and MySQL client with the following commands.
Start the MySQL service and set it to start automatically at boot.
Make sure the mysql service is running by checking its status with the following command:
The status of the mysql service should be "active (running)":
Step 5: Disable SELINUX
Run the following commands to disable SELinux:
Step 6: Install Firewall and Open ProcessMaker's Port
By default, CentOS 7 can not work without firewall, therefore it is recommended to install Firewalld so it can be easily configured. Firewalld is a dynamic daemon that manages firewall with support for networks zones. To install it run the following command:
Then, set the service to start automatically.
After that, open the port where ProcessMaker will run, which is port 80 by default. To use a port other than port 80, then it is necessary to change the port number using the following command.
