Purposes:
现在需要将一个文件发送到多个服务器上, 作为非运维的程序员, 我们应该如何解决这个问题呢?
答案是脚本啊
直接一点
一、人生苦短, 我选python
import paramiko
, sys
from collections
import defaultdict
port
="xx"
username
="xxx"
Machines
= {
'1' : ['xx.xx.xx.xx', 'password']
}
if __name__
== '__main__':
print("发布版本 例如:python send_version.py VERSION")
print("本脚本环境依赖paramiko")
print(Machines
)
tag
= input("请输入服务器编号：")
if isinstance(tag
, str):
destination
= Machines
[tag
][0]
des_password
= Machines
[tag
][1]
package
= "path" + sys
.argv
[1] + ".tar.gz"
ssh
= paramiko
.SSHClient
()
ssh
.set_missing_host_key_policy
(paramiko
.AutoAddPolicy
())
ssh
.load_system_host_keys
()
ssh
.connect
(destination
, port
, username
, des_password
)
cmd
= "sudo su & /path/send_version.sh " + package
print(cmd
)
stdin
, stdout
, stderr
= ssh
.exec_command
(cmd
)
result
=stdout
.readlines
()
print(result
)
如何避免scp无尽的密码输入: 利用shell 的expect
下面两个文件是要放到终端主机(文件目的地)上的
send_version.sh 如下:
src_path
='/path/'+
$4 +
'.tar.gz'
dest_path
='/destination/'
main
()
{
echo "发送版本 " $3 " 到 ip:" $1
expect /home/ubuntu/version/send_version.exp
$1 $2 $4 $src_path $dest_path
}
main
$1 $2 $3 $4
send_version.exp 如下:
set timeout -1
set host
[linux
$argv 0
]
set username
[linux
$argv 1
]
set passwd [linux
$argv 2
]
set src_path
[linux
$argv 3
]
set dest_path
[linux
$argv 4
]
spawn
scp -P 57522
$username@$host:$src_path $dest_path
expect {
"(yes/no)?"
{
send
"yes\n"
expect "*assword:" {send
"$passwd\n"}
}
"*assword:"
{
send
"$passwd\n"
}
}
expect eof
exit
