Versions

  • For COmanage Registry 1.0.x and earlier, PHP 5.2.8 or later is required.
    • (warning) The GitHub Provisioning Plugin requires PHP 5.4. It may be necessary to delete this plugin to use an earlier PHP version.
    • PHP 7 is not supported.
  • For COmanage Registry 2.0.0 and later, PHP 5.4 or later is required.
    • PHP 7 is supported. The use of PHP 7.0.10 or later is recommended, as earlier version have known bugs that may cause segmentation faults under Apache.
      • PHP 7.1 and 7.2 are supported starting with COmanage Registry 3.1.0.
    • The Crowd Provisioning Plugin requires PHP 7.0 or later.
    • The LDAP Source Plugin requires PHP 5.6 or later.
    • The Password Authenticator Plugin requires PHP 7.0 or later (PHP 5.5 or later for Registry 3.1.x).

(warning) Regardless of the minimum version requirements, it is strongly recommended to use a version of PHP that is not EOL (currently 5.6 or later).

(info) Installations with more than a thousand or so CO Person records should consider using PHP 7, which features improved memory utilization.

Build Options

Depending on your requirements, you may need the following PHP options:

PHP Functionality

Required?

Build Option

Debian Package1

RHEL Package2

XSL

Yes

--with-xsl

php*-xsl

php-xsl

An appropriate database option

Yes

eg --with-pgsql --with-pdo-pgsql or --with-mysql --with-pdo-mysql3

php*-pgsql or php*-mysqlphp-pgsql or php-mysql

OpenSSL

If COmanage will connect directly to an SMTP server to send mail, using SSL or TLS

--with-openssl

Enabled by defaultphp-openssl

mbstring

For multi-byte string support in data normalization

--enable-mbstring

Enabled by defaultphp-mbstring

LDAP

In order to use any LDAP based plugin (including the LDAP Provisioning PluginLDAP Identifier Validator Plugin, or LDAP Source Plugin)

--with-ldap

php*-ldapphp-ldap
GD2To make use of QR codes exposed for enrollment flow starting points, the GD2 image library is required--with-gdphp*-gdphp-gd

Notes

1Debian packages use the PHP version number (eg: 5 or 7.0) in place of the *.

2Not all packages are available in the default repos.

3Both regular and PDO are required, with the former used by ADOdB and the latter used by CakePHP.

PHP 5.4.0 Enables Strict Error Reporting

As of PHP 5.4.0, PHP ships by default with strict logging enabled. As of CakePHP 2.0.5, this will cause failures during setup. This can be disabled in php.ini by setting

error_reporting = E_ALL & ~E_STRICT

PCRE Bug May Cause Problems

There are known issues with earlier versions of the PCRE library that will cause COmanage Registry to be unable to set up its database tables. Version 6.6 and earlier are known to have problems, while versions 8.02 and later are known to work. You can check the version that PHP was built against by running this command:

php -r 'phpinfo();' | grep PCRE

If you are using an old version of PCRE, you'll first need to install a more recent version. Be sure to configure it with the --enable-utf8 --enable-unicode-properties flags. You'll then need to rebuild PHP against the newer version of the PCRE library.

Alternately, you may be able to rebuild PHP using its own internal copy of PCRE. As of PHP v5.3.3, PCRE 8.02 or later is included by default.

The database setup step may throw errors like Error: Database connection "Mysql" is missing, or could not be created. if the command line php client can't find the PDO libraries. One way to ensure their availability is to build PHP --with-pdo-mysql (or with the appropriate flag for the database you are using).

You can test for this with php -r 'phpinfo();' | grep pdo:

$ php -r 'phpinfo();' | grep pdo
pdo_mysql
pdo_mysql.default_socket => /var/lib/mysql/mysql.sock => /var/lib/mysql/mysql.sock
pdo_sqlite

If the PDO libraries show correctly but you are still getting this error, you may be trying to connect via the default socket (ie: "localhost") instead of TCP (ie: "127.0.0.1"), and the PDO libraries may not be able to find the default socket.

Testing PHP Database Connectivity

PHP will work with many different database servers. You may wish to test that PHP was built with support for MySQL or PostgreSQL (or whatever database you are using). You should have already installed and configured the database server and (in this example) have created a user named registry_user.

To test if PHP was built with support for MySQL create the file mysql-test.php with contents

<?php
mysql_connect("localhost", "registry_user", "a password goes here") or die(mysql_error());
echo "Connected to MySQL<br/>";
?>

To test if PHP was built with support for PostgreSQL create the file postgreSQL-test.php with contents

<?php
pg_connect("host=localhost dbname=test user=registry_user password=password") or die(pg_last_error());
echo "Connected to PostgreSQL<br/>";
?>

Either run the command line php tool on the file or serve it from your webserver and make sure that the script can connect to your database server.

Be sure to remove your test file after testing so it is not exposed on your web server.

Configuration Suggestions

As for all production PHP installations, display_errors should be set to Off in your php.ini.
