Sugarcrm Backup

[djagadu]

HI Guys,
I am new to CRM.
Please I need your help.
1.
Operating System RedHat 2.6.9-55.EL
Installed File name: sugarcrm-OS-4.5.1e-linux-installer.bin
Sugar Suite Version: Sugar Open Source 4.5.1e
Webserver version: PHP-4.4.3
MySQL Server Version: Mysql-5.0.24

I cannot make Sugar backup from the sugar application screnn.
Backup folder (my sugaer home): /opt/sugarcrm-4.5.1e/backup
File Name: 30Octo7.zip

Error Message: Backup directory does not exist, and could not be created.
Backup directory exists, but is not writable.

sugar is owned by root
The location is read / write (is the Sugar Home directory)


2. I cannot connet to mysql
Error Message on command line is:
[root@asterisk /]# mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

1. You may need to put propoer permissions to the backup folder. Try running backup after applying proper permissions with the command:
chmod -R 766 opt/sugarcrm-4.5.1e/backup

2. You typically connect to mysql using
mysql -u root -p

The message means that your mysql is off or you have two mysqls on the same server and one of them is off. What is the other software you are running on the server that can use mysql?
