第一次写python项目，有不好的地方请多多指正交流，背景是由于遇到项目上线时，需要登录多台服务器重启对战服务器，webhook不合适，所以开发了一个小型的远程命令分发工具，在配置文件中配置服务器列表执行命令就可以把命令远程分发到每台服务器，并在日志中记录命令执行的结果
-
部署
git clone https://github.com/EwingYangs/remote-batch-task cd remote-batch-task pip3 install -r requirements.txt -
配置服务器文件在lib/config.py，本程序保证不会保存配置文件的服务器信息，放心使用
Server = [ {"host":"192.168.1.222", "port":"22", "username":"root", "password":"123456"}, {"host":"192.168.10.10", "port":"22", "username":"root", "password":"123456"}, {"host":"192.168.33.10", "port":"22", "username":"vagrant", "password":"vagrant"}, ] -
命令
-h, --help show this help message and exit -t TASK, --task=TASK 任务类型，cmd,getfile,putfile -c COMMAND, --command=COMMAND 命令，用引号，-c 'ls -al' -l LOCALFILE, --localFile=LOCALFILE 上传本地文件路径 -r REMOTEFILE, --remoteFile=REMOTEFILE 远程文件路径，上传或下载文件都必须传 -
demo
-
重启所有服务器的swoole服务器
python rbt.py -t cmd -c 'kill -USR2 `cat \tmp\socket.pid`' -
上传本地文件/usr/local/test.py到所有服务器的/tmp/test.py
python rbt.py -t putfile -l '/usr/local/test.py' -r '/tmp/test.py' -
下载所有服务器文件/tmp/test.py到本地
python rbt.py -t getfile -r '/tmp/test.py'

运行结果

作为第三方库调用
from remote-batch-task.lib.batch batch_client = batch.BatchTask() # 命令分发，在日志中查看结果，没有返回 batch_client.batch_cmd('ls -al') # 文件上传 batch_client.batch_putfile('/usr/local/test.py', '/tmp/test.py') # 文件下载 batch_client.batch_getfile('/tmp/test.py') -
未完善点
-
暂时不能用key登录服务器，后续完善
-
错误未解决
/usr/local/lib/python3.7/site-packages/paramiko/kex_ecdh_nist.py:39: CryptographyDeprecationWarning: encode_point has been deprecated on EllipticCurvePublicNumbers and will be removed in a future version. Please use EllipticCurvePublicKey.public_bytes to obtain both compressed and uncompressed point encoding.
