TO make a database backup in postgreslq server you use pg_dump and psql commands.

First, locate the database:

# psql -l --username postgres --password

Then:

# pg_dump --username postgres name_db --file /dir/dir/backup.sql

To restore the database:

First create database with its respective name and roles:

# psql postgres
# postgres=# CREATE DATABASE name_db ENCODING 'UTF-8';
# postgres=# CREATE ROLE root LOGIN;

Restoring:

# psql name_db < /dir/dir/backup.sql

That’s all.

Asterisk GUI 2.0 404 URL not found (Fedora or Ubuntu)

December 26, 2009 9 comments

If you just install Asterisk gui 2.o from:

svn checkout http://svn.digium.com/svn/asterisk-gui/branches/2.0

And got a 404 URL not found <asterisk server> typing http://ip_machine:8088/asterisk/static/config/index.html or http://ip_machine:8088/static/config/index.html (without prefix)

and already did the “make checkconfig” cmd getting an “everything seems good” output.

and already Checked in Asterisk CLI:

system*CLI> http show status
HTTP Server Status:
Prefix: /asterisk
Server Enabled and Bound to 0.0.0.0:8088

Enabled URI's:
/asterisk/httpstatus => Asterisk HTTP General Status
/asterisk/manager => HTML Manager Event Interface
/asterisk/rawman => Raw HTTP Manager Event Interface
/asterisk/static/... => Asterisk HTTP Static Delivery
/asterisk/mxml => XML Manager Event Interface

Everything still seems ok….

Then:

# cp -Rfv /var/lib/asterisk/* /usr/share/asterisk/
# mv /var/lib/asterisk /var/lib/asterisk_original
# ln -s /usr/share/asterisk  /var/lib/asterisk

Let’s check it out now!
