# Mysql Isolated Servers -- a gem for testing mysql stuff
This gem provides functionality to quickly bring up and tear down mysql instances for the
purposes of testing code against more advanced mysql topologies -- replication, vertical
partitions, etc.
I developed this as part of my testing strategy for implementing http://github.com/osheroff/ar_mysql_flexmaster, but it's
been useful in developement of a couple of other projects too (http://github.com/osheroff/mmtop).
## Usage
```
$mysql_master = MysqlIsolatedServer.new(allow_output: false)
$mysql_master.boot!
puts "mysql master booted on port #{$mysql_master.port} -- access with mysql -uroot -h127.0.0.1 --port=#{$mysql_master.port} mysql"
$mysql_slave = MysqlIsolatedServer.new
$mysql_slave.boot!
puts "mysql slave booted on port #{$mysql_slave.port} -- access with mysql -uroot -h127.0.0.1 --port=#{$mysql_slave.port} mysql"
$mysql_slave_2 = MysqlIsolatedServer.new
$mysql_slave_2.boot!
puts "mysql chained slave booted on port #{$mysql_slave_2.port} -- access with mysql -uroot -h127.0.0.1 --port=#{$mysql_slave_2.port} mysql"
$mysql_slave.make_slave_of($mysql_master)
$mysql_slave_2.make_slave_of($mysql_slave)
$mysql_slave.set_rw(false)
sleep if __FILE__ == $0
