My problem is that the ownCloud web page does not seem to start even though
Apache and mariadb are both able to start.
This is a fresh install and I have started to run into this problem. I was
able to install ownCloud on this same configuration last year (2014) and I was
able to get it to work. So looking form some advice of what I may have missed
on this install or if something changed in one of the configuration files since
then.
This is my set-up:
- ownCloud Administrators Manual (Release 7.0 from August 29th, 2014)
- CentOS 7 with all current OS updates installed.
- SELinux is in "Permissive Mode"; so it is *NOT* enforcing any rules, only
logging.
- Using the openSUSE Build Service option from the ownCloud Administrators
Manual and have added the repo for CentOS 7 and installed "owncloud" from
there.
When I boot or restart the httpd & mariadb services I get this error message
from Apache:
Error message from /var/log/httpd/error_log:
[Wed Jan 28 14:48:17.206407 2015] [:error] [pid 3273] [client ::1:37298] PHP
Fatal error: Class 'PDO' not found in
/var/www/html/owncloud/3rdparty/doctrine/dbal/lib/Doctrine/DBAL/DriverManager.php
on line 148
I am using the stock DriverManager.php file that came with the installation
package and I have not made any modifications so I though I would include the
sha1sum of that file if it helps in determining if newer files have any changes:
189342d4457174e165a0ff16b9c6d4aa09538b0a
When I go to that DriverManager.php file and locate the block of code around
line 148 this is what it says:
[CODE]
122 // check for existing pdo object
123 if (isset($params['pdo']) && ! $params['pdo'] instanceof \PDO) {
124 throw DBALException::invalidPdoInstance();
125 } else if (isset($params['pdo'])) {
126 $params['pdo']->setAttribute(\PDO::ATTR_ERRMODE,
\PDO::ERRMODE_EXCEPTION);
127 $params['driver'] = 'pdo_' .
$params['pdo']->getAttribute(\PDO::ATTR_DRIVER_NAME);
128 } else {
129 self::_checkParams($params);
130 }
131 if (isset($params['driverClass'])) {
132 $className = $params['driverClass'];
133 } else {
134 $className = self::$_driverMap[$params['driver']];
135 }
136
137 $driver = new $className();
138
139 $wrapperClass = 'Doctrine\DBAL\Connection';
140 if (isset($params['wrapperClass'])) {
141 if (is_subclass_of($params['wrapperClass'], $wrapperClass)) {
142 $wrapperClass = $params['wrapperClass'];
143 } else {
144 throw
DBALException::invalidWrapperClass($params['wrapperClass']);
145 }
146 }
147
148 return new $wrapperClass($params, $driver, $config, $eventManager);
[/CODE]
Searching on the web it appears that PDO in php is related to interaction with
databases "Represents a connection between PHP and a database server." I
installed mariadb and mariadb-server as well as Apache (httpd); Both are
started and can be restarted via systemd without a problem. I know that httpd
is running because I can get the standard CentOS error/welcome message on the
root of the web server, but when I try to go to http://localhost/owncloud it
does nothing.
Because it seems like PDOs interact with databases, I checked my log for
mariadb from /var/log/mariadb/mariadb.log and didn't see anything that looks
like a problem, but here is the log:

Any advice what I could check for next?
Many thanks!
