Python - 通过Python 制作简易的一键部署脚本

Python - 通过Python 制作简易的一键部署脚本

---

1、定义流程

部署的流程是一致的，只是服务器信息不一样，服务器的部署形式，部署路径不一样，所以

1、创建标准的部署模版
2、创建服务器配置
3、创建部署配置

2、创建标准的部署模版

import paramiko
import time


def command(ssh_config, cmd, need_print=None):
    ssh = paramiko.SSHClient()
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh.connect(hostname=ssh_config.hostname, port=ssh_config.port, username=ssh_config.username,
                password=ssh_config.password)
    stdin, stdout, stderr = ssh.exec_command(cmd)
    result = stdout.read()
    if need_print:
        print(result)
    ssh.close()


def upload_new(ssh_config, local, server):
    client, transport = sftp(ssh_config)
    client.put(local, server)
    transport.close()


def sftp(ssh_config):
    transport = paramiko.Transport(ssh_config.hostname, ssh_config.port)
    transport.connect(username=ssh_config.username, password=ssh_config.password)
    client = paramiko.SFTPClient.from_transport(transport)
    return client, transport


def auto_deploy(deploy_config, ssh_config):
    print('Step 1 : stop application')
    command(ssh_config, deploy_config.stop_cmd)
    print('wait for application stop')
    time.sleep(2)
    print('Step 2 : delete old application file')
    command(ssh_config, deploy_config.delete_cmd)
    print('Step 3 : upload new application file to server')
    upload_new(ssh_config, deploy_config.local, deploy_config.server)
    print('Step 4 : run application')
    command(ssh_config, deploy_config.start_cmd)
    print('deploy application completed')

3、创建服务器配置

hostname = '47.114.***.**'
port = 22
username = 'root'
password = '****'

4、创建部署配置

# 停止命令
stop_cmd = 'pkill -f nsbd.jar'
# 删除命令
delete_cmd = 'rm -f /usr/local/spring-service/nsbd/nsbd.jar'
# 本地jar 包位置
local = 'C:/Users/A-PC/Desktop/nsbd.jar'
# 服务器jar 包位置
server = '/usr/local/spring-service/nsbd/nsbd.jar'
# 启动服务命令
start_cmd = '''
    nohup java -jar \
        /usr/local/spring-service/nsbd/nsbd.jar \
        --server.port=30001 \
        > /usr/local/spring-service/nsbd/console-30001.log 2>&1 &
    '''

5、创建运行脚本

from auto_deploy.nsbd import ssh_config
from auto_deploy.nsbd import deploy_config
from auto_deploy import auto_template

if __name__ == '__main__':
    auto_template.auto_deploy(deploy_config, ssh_config)

6、延展性

进行不同的服务器，不同的环境部署，只需要复制一套配置，修改好配置即可
