ruby公用模块-logger和ssh

1、日志模块

require "logger"

#log = Logger.new(STDOUT)
#log.level = Logger::WARN
#log.debug("Created logger")
#log.info("Program started")
#log.warn("Nothing to do!")

logger = Logger.new('logfile.log',10,1024000)

#logger = Logger.new("./log/"+(Time.now).strftime("%Y-%m-%d")+"_credit.log", 'daily')

logger.info("test")

2、ssh远程访问linux

#先获取ssh的gem包：gem install net-ssh
require "net/ssh"
       
     Net::SSH.start("172.21.1.48", "username", :password => "XXXX") do |ssh|
       result = ssh.exec!("date +\"%Y%m%d%H%M%S\"")
       puts result
     end
