Make the following revisions in the my.ini file, and then save the file:

  • Set the variable max_connections = 1000.

  • Add the line skip-name-resolve at the end of the file.

Possible MySQL Errors During the Installation

If you had any problem during the installation, see MySQL Possible Configuration Issues.

Step 2: Install Apache 2.4

To install Apache 2.4 for ProcessMaker, follow these steps:

  1. Download the Apache 2.4.x VC14 binary file (64-bit version) from the Apache Haus or Apache Lounge page.

    • Apache Haus:

    • Apache Lounge:

  2. The selected binary must be compiled with VC++ 2015. For instructions on how to do this, see the Visual C++ Redistributable for Visual Studio 2015 page.

  3. Select the language of the operating system and then click the Download button.

  4. Click the checkbox next to the option VSU_4\vcredist_x64.exe and click on the Next button in the lower right corner of the screen. The file vcredist_x64.exe starts downloading automatically.

  5. After the download is finished, install the file vcredist_x64.exe as the administrator.

  6. After installation, create a folder with the name opt and extract the file to C:\opt.

  7. Add the Apache path to the Windows environment variables. Run cmd.exe as administrator and execute the following command:

    setx /M PATH %PATH%;C:\opt\Apache24\bin
  8. Edit the Apache file httpd.conf located at C:\opt\Apache24\conf\httpd.conf

    Do these changes:

    • Change the lines:

      Define SRVROOT "/Apache24" ServerRoot "${SRVROOT}"


      Define SRVROOT "C:/opt/Apache24" ServerRoot "${SRVROOT}"
    • Add the following lines to the end of the httpd.conf file:

      #KeepAlive KeepAlive On KeepAliveTimeout 15 MaxKeepAliveRequests 100 Timeout 60 #Avoid MPM related problems AcceptFilter http none AcceptFilter https none # WinNT MPM ThreadsPerChild      1000 MaxRequestsPerChild    0
    • Enable the following lines by erasing the "#" symbol at the beginning of each line:

      EnableMMAP off EnableSendfile off LoadModule alias_module modules/ LoadModule authnz_ldap_module modules/ LoadModule access_compat_module modules/ LoadModule deflate_module modules/ LoadModule expires_module modules/ LoadModule filter_module modules/ LoadModule headers_module modules/ LoadModule ldap_module modules/ LoadModule rewrite_module modules/ LoadModule ssl_module modules/ LoadModule vhost_alias_module modules/
    • By default, the httpd.conf file is configured to listen to all incoming addresses on port 80. However, it may need to be configured to listen on specific ports, or only to selected addresses depending on your server.

      For example:

      To make the server accept connections on both port 80 and port 8000 on all interfaces.

      Listen 80 Listen 8000

      To make the server accept connections on port 80 for one interface and port 8000 for another, use:

      Listen Listen
    • Save the changes and close the httpd.conf file.

  9. In the command line, proceed to install Apache. cd C:\opt\Apache24\bin httpd -k install httpd -k start

Possible Apache Errors During the Installation

If you had any problem during the installation, see Apache Possible Configuration Issues.

Step 3: Install PHP 7.1

To download the PHP binary file, click the following link: PHP Download.

Follow these steps to install PHP 7.1:

  1. Decompress the .zip file in C:\opt and rename the PHP folder as C:\opt\php.

  2. Change the name of the file php.ini-development to php.ini. This file is located at: C:\opt\php\php.ini-development.

  3. Do these changes in the php.ini file:

    • Set the following configurations:

      short_open_tag = On memory_limit = 512M error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT display_errors = Off max_execution_time = 60 post_max_size = 40M upload_max_filesize = 20M max_input_vars = 8000 extension_dir = "C:\opt\php\ext" zend_extension=php_opcache.dll
    • Add or set the following configuration for opcache:

      [opcache] ; Determines if Zend OPCache is enabled opcache.enable=1 ; Determines if Zend OPCache is enabled for the CLI version of PHP opcache.enable_cli=0 ; The OPcache shared memory storage size. opcache.memory_consumption=128 ; The amount of memory for interned strings in Mbytes. ;opcache.interned_strings_buffer=4 ; The maximum number of keys (scripts) in the OPcache hash table. ; Only numbers between 200 and 100000 are allowed. opcache.max_accelerated_files=10000 ; The maximum percentage of "wasted" memory until a restart is scheduled. opcache.max_wasted_percentage=5 ; When this directive is enabled, the OPcache appends the current working ; directory to the script key, thus eliminating possible collisions between ; files with the same name (basename). Disabling the directive improves ; performance, but may break existing applications. opcache.use_cwd=1 ; When disabled, you must reset the OPcache manually or restart the ; webserver for changes to the filesystem to take effect. opcache.validate_timestamps=1 ; If enabled, a fast shutdown sequence is used for the accelerated code opcache.fast_shutdown=1
    • Uncomment the following extensions (remove the ";" symbol at the beginning of each line):

      extension=php_curl.dll extension=php_gd2.dll extension=php_ldap.dll extension=php_mbstring.dll extension=php_mysql.dll extension=php_openssl.dll extension=php_pdo_mysql.dll extension=php_soap.dll extension=php_opcache.dll
    • Verify if the next extensions are enabled:

      extension=php_bz2.dll extension=php_exif.dll extension=php_fileinfo.dll extension=php_gettext.dll extension=php_gmp.dll extension=php_gd2.dll extension=php_mysqli.dll extension=php_openssl.dll extension=php_pdo_sqlite.dll extension=php_pdo_mysql.dll extension=php_pdo_odbc.dll extension=php_shmop.dll extension=php_soap.dll extension=php_shmop.dll extension=php_sockets.dll extension=php_sqlite3.dll extension=php_xsl.dll
    • Save the changes and close the php.ini file.

  4. Add the PHP path to windows environment variables by running cmd.exe as administrator, and execute the following command:

    setx /M PATH %PATH%;C:/opt/php
  5. Reopen the Apache file httpd.conf and add the following lines to the end of the file: LoadModule php7_module "C:/php/php7apache2_4.dll" AddHandler application/x-httpd-php .php # Configure the path of the php.ini PHPIniDir "C:/opt/php"

  6. In the Command Prompt console go to the folder C:/opt/php and run the following lines: copy libsasl.dll C:\windows\system32 copy ssleay32.dll C:\windows\system32 copy libeay32.dll C:\windows\system32 copy libssh2.dll C:\windows\system32 copy libsasl.dll C:\windows\sysWOW64 copy ssleay32.dll C:\windows\sysWOW64 copy libeay32.dll C:\windows\sysWOW64 copy libssh2.dll C:\windows\sysWOW64

    These commands will copy and paste those DLL files to System32 and SysWOW64 directories

  7. Restart the Apache service to apply the previous changes to the php.ini and httpd.conf.

    Execute the following command in the console. cd C:\opt\Apache24\bin httpd -k stop httpd -k start

Step 4: Install and Configure NSSM

Available Version: As of ProcessMaker 3.4.0.

Follow the next steps to install and configure the NSSM Supervisor:

Note: Check if ProcessMaker files have the correct owner and permissions.

  1. Download the latest version of the NSSM application from

  2. After decompressing the contents of the zip file, copy the nssm.exe file to the folder C:\opt\. This file could be placed anywhere, but it is recommended to place all related to ProcessMaker in the same place.

  3. Open the Windows console as administrator and go to C:\opt\.

  4. Run the command.

    nssm install processmaker-jobs-<WORKSPACE>

    Specify the workspace where the jobs will run. For example:

    nssm install processmaker-jobs-workflow
  5. The last command displays a window with several tabs. Go to the Application tab.

    • In the Path field, enter the path where the PHP executable is located, usually C:\opt\php\php.exe.
    • In the Startup directory field, enter the path where ProcessMaker is installed, usually C:\opt\processmaker.
    • In the Arguments field, enter the queue command specifying the workspace. processmaker artisan queue:work --workspace=<WORKSPACE>

  6. Go to the Details tab. In the Display name field, enter ProcessMaker Jobs for <WORKSPACE>. This value helps ProcessMaker identifies jobs easily in the Windows Services Panel.

  7. Save the configuration. It is not necessary to modify the other fields.

  8. Start the service by running the following command.

    nssm start processmaker-jobs-<WORKSPACE>

    Specify the workspace, for example:

    nssm start processmaker-jobs-workflow

    Alternatively, you can open the Windows Services Panel, look for the created service and stop and start it:

  9. Depending on the Company’s security policies, additionally, in the Log on tab, you can configure the account that will run the service.

Recommended Step: Optimize Server for Performance

As a best practice, it is recommended to apply the following configuration to optimize the server for performance:

  1. Modify the C:\Windows\System32\drivers\etc\hosts hosts file: localhost ::1 localhost #You can add here your domain. By example:
  2. Restart the server:

    cd c:\opt\Apache24\bin httpd -k restart
  3. Finally, change the max_execution_time value in the C:\opt\php\php.ini file and then restart the Apache service:

    max_execution_time = 60
