python fabric
该神器可以完成远程登录linux系统,并执行脚本等功能
安装
pip install fabric
使用
通过fabric.Connection方法连接服务器:
conn = fabric.Connection(host , user = ‘root’,port = 22, config = None, geteway = None, connect_kwargs={“password”: “123456”})
Connection参数的含义:
def __init__(
self,
host, #主机ip
user=None, #用户名
port=None, #ssh端口,默认是22
config=None, #登录配置文件
gateway=None, #连接网关
forward_agent=None, #是否开启agent forwarding
connect_timeout=None, #设置超时
connect_kwargs=None, #设置 密码登录connect_kwargs={"password": "123456"}) 还是 密钥登录connect_kwargs={"key_filename": "/home/myuser/.ssh/private.key"}
inline_ssh_env=None,
)
通过fabric安装软件
下面通过一段代码实现在Ubuntu上批量卸载docker,顺序取走列表中的ip。
import fabric
def docker_install():
for host in ['10.224.106.21']:
conn = fabric.Connection(host , user = 'root', connect_kwargs={<!-- -->"password": "123456"})
print("%s:" % host)
conn.run("echo Y|apt-get remove docker.io")
docker_install()
cnn获取Connetction对象后,有很多属性方法可以使用,介绍下几个常用的:
run: #执行远程命令,如:run('uname -a')
cd: #切换远程目录,如:cd('/root'); with conn.cd('/root'):继承这个状态
put: #上传本地文件到远程主机,如:put('/root/test.py','/root/test.py')
get: #获取服务器上文件,如:get('/root/project/test.log')
sudo: #sudo方式执行远程命令,如:sudo('service docker start')
