Question

我刚刚设置了一个openshift wordpress应用程序环境（http://eigenbouw-vanhove.rhcloud.com/），但我无法连接到mysql数据库。我添加了phpmyadmin盒式磁带，我想我在我的wp-config中设置了正确的信息。

我在浏览网站时遇到的错误：

建立数据库连接时出错

我的wp-config：

$EBmysql = getenv('OPENSHIFT_MYSQL_DB_URL');
$EBmysqlUser = getenv('OPENSHIFT_MYSQL_DB_USERNAME');
$EBmysqlPass = getenv('OPENSHIFT_MYSQL_DB_PASSWORD');


// ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define('DB_NAME', 'eigenbouw');

/** MySQL database username */
define('DB_USER', $EBmysqlUser);

/** MySQL database password */
define('DB_PASSWORD', $EBmysqlPass);

/** MySQL hostname */
define('DB_HOST', $EBmysql);

/** Database Charset to use in creating database tables. */
define('DB_CHARSET', 'utf8');

/** The Database Collate type. Don't change this if in doubt. */
define('DB_COLLATE', '');

日志文件不包含任何错误：

See the manual for more instructions.

You can start the MySQL daemon with:
cd /opt/rh/mysql55/root/usr ; /opt/rh/mysql55/root/usr/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd /opt/rh/mysql55/root/usr/mysql-test ; perl mysql-test-run.pl

有什么想法吗？

Answer 1

db url不起作用，你需要使用getenv（'OPENSHIFT_MYSQL_DB_HOST'），如果使用的是缩放应用程序，也需要使用getenv（'OPENSHIFT_MYSQL_DB_PORT'）。

如果你进入你的装备并运行'env | grep MYSQL'您将看到URL变量不是WordPress连接到数据库应该是什么。

Answer 2

以下是2015年4月17日从OpenShift的示例WordPress应用程序中提取的数据库define语句：

define('DB_NAME', getenv('OPENSHIFT_APP_NAME'));
define('DB_USER', getenv('OPENSHIFT_MYSQL_DB_USERNAME'));
define('DB_PASSWORD', getenv('OPENSHIFT_MYSQL_DB_PASSWORD'));
define('DB_HOST', getenv('OPENSHIFT_MYSQL_DB_HOST') . ':' . getenv('OPENSHIFT_MYSQL_DB_PORT'));
define('DB_CHARSET', 'utf8');
define('DB_COLLATE', '');
