我在运行程序通过ssh本地脚本的麻烦。
我不确定这是否是与本地主机上的shell变量替换的问题。
当手动运行，
ssh monit@server1 'bash -s' < /u02/splunk/splunk/etc/apps/Splunk_TA_nix/bin/cpu.sh
我得到预期的输出，
CPU pctUser pctNice pctSystem pctIowait pctIdle
所有11.21 0.00 1.50 0.31 86.98
0 0.00 0.00 0.00 0.00 100.00
1 3.00 0.00 1.00 0.00 96.00 ....
但我得到
庆典：/u02/splunk/splunk/etc/apps/Splunk_TA_nix/bin/cpu.sh：没有这样的文件或目录
运行下面的代码时，
splunk_bin_dir = '/u02/splunk/splunk/etc/apps/Splunk_TA_nix/bin'
hostname = 'server1'
username = 'monit'
password = 'monit#_'
command = "/usr/bin/ssh %(username)s@%(hostname)s 'bash -s' < %(splunk_bin_dir)s/cpu.sh" % locals()
print command
ssh_new_conn = 'Are you sure you want to continue connecting'
p = pexpect.spawn(command, timeout=360)
# Handles the 3 possible connection outcomes:
# a) Ssh to the remote host for the first time, triggering 'Are you sure you want to continue connecting'
# b) ask you for password
# c) No password is needed at all, because you already have the key.
i = p.expect([ssh_new_conn,'[pP]assword:',pexpect.EOF])
print ' Initial pexpect command output: ', i
if i == 0:
# send 'yes'
p.sendline('yes')
i = p.expect(['[pP]assword:',pexpect.EOF])
print 'sent yes. pexpect command output', i
if i == 0:
# send the password
p.sendline(password)
p.expect(pexpect.EOF)
elif i == 1:
# send the password
p.sendline(password)
p.expect(pexpect.EOF)
elif i == 2:
print "pexpect faced key or connection timeout"
pass
print p.before
这些是印刷输出，
的/ usr / bin中/ SSH monit的@ server1的 'bash的-s'</u02/splunk/splunk/etc/apps/Splunk_TA_nix/bin/cpu.sh
初始Pexpect的命令输出：1

Pexpect的被碰撞到[PP] assword线，所以我想密码正确传递，
