我在生产箱上手写着文字,在生产箱中,它没有做第一次检查。 我将其缩小到我的“假”检查(通过分处理)正在退回非零结果。
这部法典最简单:
import subprocess
import sys
ip="127.0.0.1"
ping = subprocess.Popen(["ping", "-c", "2", "-w", "1", ip], shell=False)
ping.wait()
if ping.returncode != 0:
print ping.returncode, "ERROR: failed to ping host. Please check."
sys.exit(1)
else:
print "OK"
两台服务器均为CentOS 5.5 &,2.4.3,但一台作品和一台 does!
从指挥线上看,在这两种情况下,有12.01的人工计票。 为什么在 p使用分处理模块时,这些模块会有什么区别?
