Mytop error “long|!”

vicky — Tue, 17 Nov 2009 23:34:31 +0000

If you run mytop on RHEL server (or CentOS 5.x) you may get error message saying

Error in option spec: “long|!”

You should edit file /usr/bin/mytop and comment out this line

“long|!” => \$config{long_nums},

after that, run mytop and all should work fine.

Enjoy!

Ever wondered how to find out your mysql root password? Well, on Ensim server it is easy to find out.

ensim-python -c “import sys;sys.path.append(\”/usr/lib/opcenter/mysql\”);import mysqlbe;print mysqlbe.read_mysqlpass()”

It it one line command. Execute it from shell logged in as root. Works well

This tutorial section deals with mysqldump which is a tool to import and export MySQL databases.

It can be used to back up a database or to move database information from one server to another.

1. Export A MySQL Database

This example shows you how to export a database. It is a good idea to export your data often as a backup.

# mysqldump -u username -ppassword database_name > FILE.sql

Replace username, password and database_name with your MySQL username, password and database name.

File FILE.sql now holds a backup of your database, download it to your computer.

2. Import A MySQL Database

Here, we import a database. Use this to restore data from a backup or to import from another MySQL server.

Start by uploading the FILE.sql file to the server where you will be running this command.

# mysql -u username -ppassword database_name < FILE.sql

Replace the parts in red with your own information.

This powerful, easy to use command has many uses. Let’s say you wanted to switch web hosting providers.

Simply export your data on the old provider’s server and import it on your account with the new host.
