AppArmor and MySQL

MySQL accesses files in various places on the file system, and usually this isn't something to worry about. For example, in a standard MySQL 5.5 installation on Ubuntu, the data goes in /var/lib/mysql, and the socket is a file in /var/run/mysqld. It puts configuration files in /etc, logs and binaries in various locations, and it even needs to access some operating system files such as /etc/hosts.allow.

This is all very well until you start trying to be clever and get MySQL to access other parts of the file system. After all, you can configure the location of data, log files, socket, and so on, so why shouldn't you use those settings to optimize your system? Unfortunately, on many modern Linux distributions, it's not that always easy.

Take Ubuntu, for example. Ubuntu comes with something called AppArmor, a kernel-integrated application security system that controls how applications can access the file system. This goes above …

Automating MySQL access with expect and bash scripting

If you have multiple database servers with strange names, or if you have to hop over multiple machines to connect to any mysql database server, then you know what a pain it can be to administer such a setup. Thanks to some scripting, you can automate such tasks as follows:

Create an expect script:

#!/usr/bin/expect -f
#script by darren cassar

set machine [lindex $argv 0]

set timeout -1

spawn ssh username@$machine
match_max 100000
expect -exact “assword: “
send — “password\r”
send — “sudo -k; sudo su – mysql\r”
expect -exact “sudo -k; sudo su – mysql”
expect -exact “assword:”
send — “password\r”

# you should change the word password in ‘send — “password\r”‘ to your login password
# if you have the same password for each …
