如何使用Python脚本在Linux中实现远程服务器管理

import paramiko

# 远程服务器地址和登录凭据
hostname = "远程服务器地址"
username = "用户名"
passWord = "密码"

# 创建SSH客户端
client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())

# 连接远程服务器
client.connect(hostname, username=username, password=password)

# 执行命令
stdin, stdout, stderr = client.exec_command("ls")

# 输出命令执行结果
print(stdout.read().decode())

# 关闭连接
client.close()

import paramiko

# 远程服务器地址和登录凭据
hostname = "远程服务器地址"
username = "用户名"
password = "密码"

# 创建SSH客户端
client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())

# 连接远程服务器
client.connect(hostname, username=username, password=password)

# 上传文件
sftp = client.open_sftp()
sftp.put("本地文件路径", "远程文件路径")
sftp.close()

# 关闭连接
client.close()

import paramiko

# 远程服务器地址和登录凭据
hostname = "远程服务器地址"
username = "用户名"
password = "密码"

# 创建SSH客户端
client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())

# 连接远程服务器
client.connect(hostname, username=username, password=password)

# 执行top命令获取CPU利用率
command = "top -bn1 | grep %Cpu | awk '{print $2}'"
stdin, stdout, stderr = client.exec_command(command)

# 输出CPU利用率
cpu_usage = stdout.read().decode().strip()
print("CPU利用率: {}%".fORMat(cpu_usage))

# 关闭连接
client.close()
