使用python 腳本備份zk中的配置

?

python 備份代碼??? ? ? ? ? ? ? python3? back.py

            
              import os
import os.path

from kazoo.client import KazooClient
from kazoo.client import KazooState

zk = KazooClient('test:2181')
zk.start()

zkBashPath = "/conf/base/"

backUp_path = "/tmp/test/"


cs = zk.get_children(zkBashPath)

for name in cs:
    print(name)

    file_path = backUp_path + name

    if os.path.exists(file_path):
        os.remove(file_path)
        print('del file %s', file_path)

    b, stat = zk.get(zkBashPath + name)

    f = open(file_path, 'w')
    f.write(str(b, "utf-8"))

    f.close()

zk.stop()

還原代碼? reback.py

運(yùn)行： python3? reback.py? name

            
              import os
import os.path
import sys

from kazoo.client import KazooClient
from kazoo.client import KazooState

reback_name = sys.argv[1]

print(reback_name)

if reback_name is None:
    print("fine name not null")
    sys.exit(1)

zk = KazooClient('test:2181')
zk.start()

zkBashPath = "/conf/base/"

backUp_path = "/tmp/test/"

f = open(backUp_path+reback_name, 'r')

conf = f.readline()
if conf:
    zk.set(zkBashPath+reback_name, bytes(conf, "utf8"))
else:
    print("file content is blank")
