安装fabric

 

先安装pip

########################### 安装pip ########################### cd /tmp/   #ssh远程复制 #!/bin/bash passwd='hengtian@123' /usr/local/bin/expect <<-EOF set timeout -1 spawn scp -r 172.16.129.72:/ftp/www/distribute-0.6.10.tar.gz  /tmp/ expect { "*yes/no" { send "yes\r"; exp_continue } "*password:" { send "$passwd\r" } }   expect "*]"  EOF tar xf distribute-0.6.10.tar.gz cd distribute-0.6.10 python setup.py install cd /tmp/   #!/bin/bash passwd='hengtian@123' /usr/local/bin/expect <<-EOF set timeout -1 spawn scp -r [email protected]:/ftp/www/pip-1.5.4.tar.gz /tmp/ expect { "*yes/no" { send "yes\r"; exp_continue } "*password:" { send "$passwd\r" } }   expect "*]"  EOF   tar -xzvf pip-1.5.4.tar.gz cd pip-1.5.4 python setup.py install cd /usr/bin/ touch pip chgrp root pip chmod 755 pip cat > /usr/bin/pip < #!/usr/bin/python # EASY-INSTALL-ENTRY-SCRIPT: 'pip==1.5.4','console_scripts','pip' __requires__ = 'pip==1.5.4' import sys from pkg_resources import load_entry_point   if __name__ == '__main__':     sys.exit(         load_entry_point('pip==1.5.4', 'console_scripts', 'pip')()     ) EOF

 

安装完成之后 使用pip list查看版本

pip 安装fabric 1.14.0 

报错

pip 版本过低 需要升级pip版本 这边升级到10.0.0

pip install pip==10.0.1

 

升级成功pip list 查看

 

 

 

pip 安装fabric

查看脚本中所有模块

 

执行remote_update

fab -f sshkeygen.py  remote_update

 

 

会在对应虚拟机中创建authorized_keys(如果不存在的话),再将172.16.129.72和172.16.130.24的公钥加入到对应虚拟机的authorized_keys中

执行成功(这边直接贴一个之前虚拟机  执行成功的图)

添加 免密成功后，首次登陆还是会需要交互 

如果不希望 在ssh过程中弹出 图中所示交互界面 可以做如下配置

 

 

方法1

cat > ~/.ssh/config << EOF

Host *

    StrictHostKeyChecking no

EOF

方法二

修改/etc/ssh/ssh_config

#StrictHostKeyChecking ask    去掉#之后把ask 改成no 即可
