Fatal error: Out of memory (allocated +) (tried to allocate + bytes) ?

Guys,

Please increase the memory size in php.ini file. If it does not work just put following directives in the httpd.conf file and restart apache :

====
RLimitMEM 447392422
RLimitCPU 240
====

You may have increased the RLimitMEM size since above has in bytes.

OR : You can set -1 at ini_set('memory_limit', '-1'); This has in the configuration file of the script.

Try :)

DATABASE ERROR: CONNECTION FAILED! + roundcube

Guys,

If you get this error just rectify the login details in the /usr/local/cpanel/base/roundcube/config/db.inc.php file since it's clear the DB connection error.

Example :

------
root@2red [/usr/local/cpanel/base/roundcube]# cat config/db.inc.php | grep roundcube
$rcmail_config['db_dsnw'] = 'mysql://roundcube:DB_PASSWORDlocalhost/roundcube';
// postgres example: 'pgsql://roundcube:pass@localhost/roundcubemail';
root@2red [/usr/local/cpanel/base/roundcube]#
------

PS: Name of the roundcube database : roundcube
DB username : roundcube
DB password : DB_PASSWORD //it has in /root/.my.cnf file

Also give grant privileges to that db.

That's it try :)

How to install roundcube in the cpanel server?

Guys,

I referred the following steps :

-----------
cd /usr/local/cpanel/base
rm -rf roundcube*
mysql -p -e 'drop database roundcube';
chattr -i /usr/local/cpanel/base/frontend/x/webmaillogin.html
chattr -i /usr/local/cpanel/base/webmaillogin.cgi
/scripts/upcp

cd /usr/local/cpanel/base
wget http://sourceforge.net/projects/roundcubemail/files/roundcubemail/0.4.2/roundcubemail-0.4.2.tar.gz/download
tar -zxvf roundcube.tar.gz
rm -rf roundcube.tar.gz
mv -f roundcubemail-0.1-rc1 roundcube
cd roundcube
chmod -R 777 temp
chmod -R 777 logs
-----------
mysql -e "CREATE DATABASE roundcube;" -pDATABASEPASSWORD
mysql -e "use roundcube; source SQL/mysql.initial.sql;" -pDATABASEPASSWORD


Now lets sort out the configuration


cd config
mv db.inc.php.dist db.inc.php
mv main.inc.php.dist main.inc.php

Now open db.inc.php

nano db.inc.php

Find

$rcmail_config['db_dsnw'] = 'mysql://roundcube:pass@localhost/roundcubemail';


Replace with

$rcmail_config['db_dsnw'] = 'mysql://root:DATABASEPASSWORD@localhost/roundcube';



Now Open main.inc.php

nano main.inc.php

Find

$rcmail_config['default_host'] = '';


Replace with

$rcmail_config['default_host'] = 'localhost';
-----------
Now we have to configure cPanel to show roundcube in the theme. Please note this is for the X theme(default) only!! If you use another theme please skip the next part and see below.

cd /usr/local/cpanel/base/roundcube/skins/default/images/
cp --reply=yes roundcube_logo.png /usr/local/cpanel/base/frontend/x/images/roundcube_logo.png
cp --reply=yes roundcube_logo.png /usr/local/cpanel/base/webmail/x/images/roundcube_logo.png
cd /usr/local/cpanel/base
wget http://www.hostgeekz.com/files/hostgeekz/HGpatch-roundcube-0.1-rc1
patch -p0 < HGpatch-roundcube-0.1-rc1
----------

chattr +i /usr/local/cpanel/base/frontend/x/webmaillogin.html
chattr +i /usr/local/cpanel/base/webmaillogin.cgi

How to migrate Plesk data manually with Plesk Migration Manager?

Manually migration?

[How to] How to migrate Plesk data manually with Plesk Migration Manager?
Article ID: 1152
Last Review: Nov,24 2009 Author: Bezborodova Anastasiya
Last updated by: Bezborodova Anastasiya APPLIES TO:
Plesk 8.x for Linux/Unix
Plesk 9.x for Linux/Unix
Resolution
To do this follow the steps below:

1. Upload migration agent and modules to the source server. For example for Parallels Plesk Panel, there are two folders: /usr/local/psa/PMM/agents/shared and /usr/local/psa/PMM/agents/PleskX. Use the command below to copy the Migration Manager:

destination ~# scp -r /usr/local/psa/PMM/agents/shared/* /usr/local/psa/PMM/agents/PleskX/* root@source:/temporary_migration_directory/

2. Login to source server and change to directory /temporary_migration_directory.
Run migration agent (PleskX.pl) with parameter --help to get all available options of the migration agent. Start dumping with options you need. For example:

source ~# cd /temporary_migration_directory
temporary_migration_directory ~# chmod 755 PleskX.pl
temporary_migration_directory ~# ./PleskX.pl --dump-all

3. This will create dump configuration file dump.xml and content dump archives in current directory /temporary_migration_directory.

4. On the destination server create directory /work_dir and copy file dump.xml from /temporary_migration_directory to it.:

source ~# scp /temporary_migration_directory/dump.xml root@destination:/work_dir/

5. On destination Parallels Plesk Panel 8 create subdirectory /work_dir/archives and copy other content dump files to this directory:

source ~# scp -r /temporary_migration_directory/* root@destinationPPP8:/work_dir/archives/

On destination Parallels Plesk Panel 9 dump.xml and all other content files should locate in the same directory. So copy all other files into /work_dir/:

source ~# scp -r /temporary_migration_directory/* root@destinationPPP9:/work_dir/

6. Deploy the data through Parallels Plesk Panel GUI.

Login to Parallels Plesk Panel (PPP) as administrator and change to the Migration Manager page. The page is Server -> Migration Manager in PPP version 8.x and Home -> Migration Manager in PPP version 9.x

Click button "Start a new migration" and choose "Data import" in PPP version 8.x or "Transfer data already processed by the migration agent and located on the local host." in PPP version 9.x.

In version 8.x pay attention for choosing correct Working directory for the data importing, it should the directory where you put the data to be restored (/work_dir).
In version 9.x put location of dump.xml file in the "Migration data file location" field. It should be /work_dir/dump.xml.

Additional information
In Parallels Plesk Panel version 9 restoration logs of manual migration are located on page Backup Manager at Home -> Backup Manager. So that is normal that you you see the Home page after specifying "Migration data file location" and click Next.
