任何数据库都需要备份和恢复,,这个重要性就不多说了,大家都懂的。
MongoDB也提供了备份和恢复的功能,分别是MongoDB下载目录下的mongdump.exe和mongorestore.exe文件。
首先说下语法:
备份:
>mongodump -h dbhost -d dbname -o dbdirectory
-h:MongDB所在服务器地址,例如:127.0.0.1,当然也可以指定端口号:127.0.0.1:27017
-d:需要备份的数据库实例,例如:test
-o:备份的数据存放位置,例如:c:\data\dump,当然该目录需要提前建立,在备份完成后,系统自动在dump目录下建立一个test目录,这个目录里面存放该数据库实例的备份数据。
实例:>mongodump -h 127.0.0.1 -d test -o c:\data\dump\
恢复:
>mongorestore -h dbhost -d dbname --directoryperdb dbdirectory
-h:MongoDB所在服务器地址
-d:需要恢复的数据库实例,例如:test,当然这个名称也可以和备份时候的不一样,比如test2
--directoryperdb:备份数据所在位置,例如:c:\data\dump\test,这里为什么要多加一个test,而不是备份时候的dump,读者自己查看提示吧!
--drop:恢复的时候,先删除当前数据,然后恢复备份的数据。就是说,恢复后,备份后添加修改的数据都会被删除,谨慎使用!
实例:>mongorestore -h 127.0.0.1 -d test --directoryperdb c:\data\dump\test

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
