django中执行shell脚本

最开始启动一个进程：

1：p = create_multiprocess(target=getsmoketest,
 args=[intranetip, username, password])

 def create_multiprocess(target, args=()):
 p = multiprocessing.Process(target=target, args=args)
 p.start()
 return p
2script_path = os.path.join(BASE_DIR, "common/smoketestreport/runsmoketestcases.sh")
args = ["sh", "-x", script_path, self.ip, self.user, self.password, BASE_DIR]
exit_value = 1
try:
 process = subprocess.Popen(args, bufsize=1, stdout=subprocess.PIPE, close_fds=True, preexec_fn=os.setsid,
 universal_newlines=True)
 while process.poll() is None:
 out_put_log = process.stdout.readline()
 self.logger.output_shelllog_to_logger(out_put_log)
 process.wait()
 exit_value = process.returncode
except Exception, e:
 self.logger.error(e.message)
if exit_value != 0:
 err_msg = "[DevOps_Error]:Execute " + script_path + " error!!!"
 self.logger.error(err_msg)
 return self.EXCEPTION
return self.NORMAL

这样算是开始执行脚本了，但是在shell脚本有个问题：
1脚本要识别这个Django框架路径，也就是用到了BASE_DIR这个路径
2在shell脚本开启spawn的时候，最好设置set timeout -1这句话

代码：
/usr/bin/expect <<EOF 
set timeout -1 
  spawn ssh -o "StrictHostKeyChecking no" $user@$ip \[ \! -d $SMOKETESTCASESSAVEDIR/ \]  && mkdir $SMOKETESTCASESSAVEDIR/
  expect {
      "$ip's password:" { send "$password\r"; exp_continue}
      }  
  spawn scp -o "StrictHostKeyChecking no" $script_path/$sshFileName $user@$ip:$SMOKETESTCASESSAVEDIR
  expect {
      "$ip's password:" { send "$password\r"; exp_continue}
      }      
  spawn scp -o "StrictHostKeyChecking no" $script_path/threadnameconfig.xml $user@$ip:$SMOKETESTCASESSAVEDIR
  expect {
      "$ip's password:" { send "$password\r"; exp_continue}
      }
  spawn ssh -o "StrictHostKeyChecking no" $user@$ip sh $SMOKETESTCASESSAVEDIR/$sshFileName
  expect {
      "$ip's password:" { send "$password\r"; exp_continue}
      }      
  spawn scp -o "StrictHostKeyChecking no" $user@$ip:$SMOKETESTCASESSAVEDIR/checkprojectrun.log $SMOKETESTCASESSAVEDIR
  expect {
      "$ip's password:" { send "$password\r"; exp_continue}
      }
EOF
