Ruby多线程与多进程示例

多进程示例：

multiprocess.rb

def test_proc(name,second)
  Process.setproctitle("PROC-#{Process.pid}" )
  sleep second
  puts "#{name} - #{Process.pid} |G/U:#{Process.euid}/#{Process.gid}|PPID:#{Process.ppid}"
  Process.exit
  puts "Never going here"
end

puts "Main process start - #{Process.pid}"

10.times do |t|

    Process.fork do
      test_proc("PROC-#{t}",5+t)
    end

end

#Process.exit
Process.waitall
puts "Main process exit - #{Process.pid}"

运行结果：

多线程示例：

multithread.rb

require "thread"

threads=[]
6.times do |t|
  threads <<Thread.new do
    puts "Thread-#{t} start: Process: #{Process.pid} "
    sleep 5
    puts "Thread-#{t} Done: Process: #{Process.pid} "
  end
end

threads.each{|t|t.join}

运行结果：
