Quick Start

To run Vultr-Aliyun tool:

python3 vultr.py

And you can see a list of all your records and main menu.

Then select 13 to start monitoring.

It's better if you run this tool as a background process, so that monitoring process will continue when you log out from SSH, and you can achieve that by using screen.

Prerequisites

• An inland linux server (Master)
• Vultr Servers (Slave)
• Aliyun Domain
• Aliyun API
• Vultr API

Requirements

• python3
• mysql
• pymysql
• Aliyun SDK
• tcping

Installation

Install Mysql

Install tcping

Install python3:

sudo apt-get install python3

Install pymysql

sudo apt-get install python3-pip
pip3 install PyMySQL

Install Aliyun SDK:

sudo pip3 install aliyun-python-sdk-core-v3

Download Vultr-Aliyun using git clone:

git clone https://github.com/Fantastic8/Vultr-Aliyun.git

Configuration

Set up Mysql:

1. Create a mysql user
2. Create a database for Vultr-Aliyun

Set up vultr.py:

cd Vultr-Aliyun
vi vultr.py

Modify the following:

MYSQL_USER = 'Your mysql user name'
MYSQL_PASSWD = 'Your mysql user password'
MYSQL_DB = 'Your mysql database name'
VULTR_KEY = 'Vultr api key'
ALI_ACCESS_KEY_ID = 'Aliyun access key id'
ALI_ACCESS_KEY_SECRET = 'Aliyun access key secret'
client = AcsClient(ALI_ACCESS_KEY_ID, ALI_ACCESS_KEY_SECRET, 'cn-hangzhou')
DOMAIN_NAME = 'Aliyun domain name'
logf_name = 'vultr.log' # vultr log file name

# interval better be greater than 5 minutes
CHECK_INTERVAL_MAX = 10 # maximum check interval (minutes)
CHECK_INTERVAL_MIN = 4  # minimum check interval (minutes)
check_int = CHECK_INTERVAL_MAX
CHECK_PORT = '1010' # slave's port which master will use tcping to check, make sure this port is open on slave server!
RANDOM_REGION = True # True: randomly select new region from REGION_LIST when detected a blocked server; False: keep the same region as the old server
REGION_LIST = ['Atlanta', 'Dallas', 'Chicago', 'Los Angeles', 'Silicon Valley', 'Seattle', 'Miami'] # regions that can be randomly selected for new server

After that, you can run vultr.py:

python3 vultr.py

Why you need a Vultr Snapshot

When you deploy a server on vultr, there is a chance that this IP will be blocked in the future. So after configuration of your server and keeping all services running, you can create a snapshot of server so that it will automatically resume to the point where you create a snapshot at when this server has been blocked.

Usage

See usage for more details.

Warning

• All vultr servers that not exist in chain record will be deleted !!!!!! Please add all your vultr servers into chain record.
• Please prepare your vultr servers, snapshots and Aliyun domain records first, then add chain record in Vultr-Aliyun.
• Please delete related chain record before you delete server instance or snapshot or domain record.
• Please check vultr.log if anything goes wrong.
• Usually need to wait until second checking interval to repair chain completely, because server needs time to reboot.
