在AWS中,可以通过使用Network Load Balancer (NLB) 和Amazon Elastic File System (EFS)来创建外部可访问的FTP端点。
以下是一个使用NLB和EFS的示例代码:
import boto3
efs_client = boto3.client('efs')
response = efs_client.create_file_system(
CreationToken='my-token',
PerformanceMode='generalPurpose',
Encrypted=False,
ThroughputMode='bursting',
ProvisionedThroughputInMibps=0.0,
Tags=[
{
'Key': 'Name',
'Value': 'my-efs'
},
]
)
file_system_id = response['FileSystemId']
print('EFS File System ID:', file_system_id)
import boto3
ec2_client = boto3.client('ec2')
response = ec2_client.create_network_load_balancer(
Name='my-nlb',
Subnets=[
'subnet-12345678',
'subnet-abcdefgh',
],
Scheme='internet-facing',
Type='network',
Tags=[
{
'Key': 'Name',
'Value': 'my-nlb'
},
]
)
nlb_arn = response['LoadBalancers'][0]['LoadBalancerArn']
print('NLB ARN:', nlb_arn)
import boto3
ec2_client = boto3.client('ec2')
response = ec2_client.run_instances(
ImageId='ami-12345678',
InstanceType='t2.micro',
KeyName='my-key-pair',
MaxCount=1,
MinCount=1,
Placement={
'AvailabilityZone': 'us-west-2a'
},
SecurityGroupIds=[
'sg-12345678',
],
SubnetId='subnet-12345678',
UserData='''#!/bin/bash
yum install -y vsftpd
systemctl start vsftpd
systemctl enable vsftpd
echo "anonymous_enable=YES" >> /etc/vsftpd/vsftpd.conf
echo "pasv_enable=YES" >> /etc/vsftpd/vsftpd.conf
echo "pasv_min_port=30000" >> /etc/vsftpd/vsftpd.conf
echo "pasv_max_port=31000" >> /etc/vsftpd/vsftpd.conf
echo "pasv_address=ftp.example.com" >> /etc/vsftpd/vsftpd.conf
systemctl restart vsftpd
'''
)
instance_id = response['Instances'][0]['InstanceId']
print('EC2 Instance ID:', instance_id)
response = ec2_client.create_tags(
Resources=[instance_id],
Tags=[
{
'Key': 'Name',
'Value': 'my-ftp-server'
},
]
)
response = ec2_client.create_target_group(
Name='my-ftp-target-group',
Protocol='TCP',
Port=21,
VpcId='vpc-12345678'
)
target_group_arn = response['TargetGroups'][0]['TargetGroupArn']
print('Target Group ARN:', target_group_arn)
response = ec2_client.register_targets(
TargetGroupArn=target_group_arn,
Targets=[
{
'Id': instance_id,
'Port': 21,
},
]
)
response = ec2_client.create_listener(
LoadBalancerArn=nlb_arn,
Protocol='TCP',
Port=21,
DefaultActions=[
{
'Type': 'forward',
'TargetGroupArn': target_group_arn,
},
]
)
现在,您应该能够访问FTP服务器,只需使用NLB的DNS名称连接到它。 请确保在DNS名称之前添加ftp://协议前缀。
请注意,这只是一个示例代码,您可能需要根据您的特定需求进行适当的调整。
