# 写了一个自动杀php进程的ruby脚本

ruby写运维脚本也是可以的~
---------------

因为发现后台老是有好多闲置的php进程没有退出，光吃资源，没干活~

于是用ruby写了个脚本到 crontab中，每隔5分钟执行一次

    #!/usr/bin/env ruby
    # 自动关闭状态为闲置（s）的php进程
    
    require 'time'
    
    def php_processes
        ps = `ps aux|grep -e '/opt/cpanel/ea-php'`
        process = Struct.new(:pid, :created_at, :status) do
            def kill()
                `kill -6 #{pid}`
            end
            def dormanted?
                %w(X S Z).include? status
            end
            def timeout?
                (Time.now-created_at).to_i > (5*60)  # 大于5分钟则关闭进程
            end
            def kill_dormanted!
                kill() if dormanted? && timeout?
            end
        end
    
        pss = []
        ps.split("\n").each do |p|
            p = p.split
            pid = p[1]
            created_at = Time.parse "#{p[8]}" rescue Time.now
            status = p[7]
            pss << process.new(pid, created_at, status)
        end
        pss
    end
    
    php_processes.each do |p|
        p.kill_dormanted!
    end
