With (R)?ex you can manage all your boxes from a central point through the complete process of configuration management and software deployment.
A small example:
set user => "root";
set password => "root";
set -passauth;
group frontend => "frontend[01..09]", "varnish[01..04]";
desc "Show Unix version";
task "uname", group => "frontend", sub {
say run "uname -a";
};
desc "Install needed packages and configurations";
task "prepare", group => "frontend", sub {
install "apache2";
install "mysql-server";
file "/path/on/the/remote/machine",
content => "Hello World!",
mode => 600,
owner => "root",
group => "root";
};
- Run commands directly from command line
bash# rex -e 'say run "uptime";' -H "frontend[01..10] middleware[01..05]" -u root -p password
- List all known Tasks
bash# rex -T
