Question

我正在将mariadb备份作业自动化为python程序。但是，由于某些原因，看来似乎--target-directory参数虽然正确传递并通过打印进行了验证，但在从os.system运行实际命令时却被忽略了。下面的代码：

import os
import datetime, time
import mysql.connector as mariadb


unix_socket = "/var/lib/mysql/mysql.sock"
currentdate = datetime.datetime.now()
bkp_path = time.strftime("/%Y/%m-%d/%H%M")
ro_status = ("show global variables like 'read_only%'")
dblist = ("show databases")
db = mariadb.connect(user='pytest', password='pytest', unix_socket=unix_socket)
cur = db.cursor()
cur.execute(ro_status)
result = cur.fetchall()
for r in result:
        if "OFF" in r:
            cur.execute(dblist)
            dbs = cur.fetchall()
            for d in dbs:
                dbstr = ''.join(d)
                bkp_path = "/backups/" + dbstr + time.strftime("/%Y/%m-%d/%H%M/")
                bkp_cmd = "sudo mariabackup --backup --databases='" + dbstr + "' --target-directory=" + bkp_path +"  --user pytest --password=pytest --no-lock"
                try:
                    os.stat(bkp_path)
                except:
                    os.makedirs(bkp_path)
                try:
                   # print(bkp_cmd)
                    os.system(bkp_cmd)
                except:
                        print("Problem running backup on this host")
        else:
            print(h + " is read only and will not be backed up")

打印命令示例： sudo mariabackup --backup --databases =“ testdbBA” --target-directory = / backups / testdbBA / 2019 / 03-06 / 1659 / --user pytest --password = pytest --no-lock

即使通过打印块单独运行-它也会尝试写入我的本地主目录而不是指定的目标目录。

它的--target-dir不是--target-directory

Mariabackup忽略--target-dir
