Instalando Templates de SiteBuilder desde Fedora a Debian | Linux Fedora Debian

Despues de migrar un servidor Fedora a uno nuevo en Debian para poder instalar los templates anteriores hay que hacer lo siguiente:

apt-get install alien

Luego generamos un archivo install.sh e incorporamos este script donde se encuentran los templates .rpm:

#!/bin/bash

#correrlo sh rpm-to-deb.sh > rpm-to-deb.log 2>&1

for i in $( ls|grep "\.rpm" ); do

alien -d $i

done

for i in $(ls|grep "\.deb"); do

dpkg -i $i

done

##dpkg -i *.deb opcion a la instalacion anterior

cp -rf /usr/local/sitebuilder/htdocs/templates/* /opt/sitebuilder/htdocs/templates/

chown www-data /opt/sitebuilder/htdocs/templates/ -R

sb_config --update_templates

Despues solo queda ejecutar dicho script dentro del folder de donde estan los .rpm:

sh install.sh

Error Access phpMyAdmin from Plesk | Plesk + phpMyAdmin

ERROR:

"#1045 - Access denied for user 'pma_xxxxxxx'@'localhost' (using password: YES)"

SOLUCION:

/usr/local/psa/admin/htdocs/domains/databases/phpMyAdmin/libraries/config.inc.php
Dentro de este archivo se encuentra los siguientes datos:
$cfg['Servers'][$i]['controluser'] = 'yourUSER';
$cfg['Servers'][$i]['controlpass'] = 'yourPASSWORD';
$cfg['Servers'][$i]['pmadb'] = 'yourDATABASE';

Para solucionar esto hacemos lo siguiente:

1. mysql -uadmin -p`cat /etc/psa/.psa.shadow`
2. use mysql;
3. insert into user values
   ('localhost','yourUSER',password('yourPASSWORD'),
   'N','N','N','N','N','N','N','N','N','N','N','N','N','N','N','N','N','N','N','N','N','N','N','N','N','N',
   '','','','',0,0,0,0);
4. INSERT INTO `db` VALUES
   ('localhost','yourDATABASE','yourPASSWORD',
   'Y','Y','Y','Y','N','N','N','N','N','N','N','N','N','N','N','N','N');
5. FLUSH PRIVILEGES;
6. EXIT
