Mongo DB是目前在IT行业非常流行的一种非关系型数据库(NoSql),其灵活的数据存储方式,备受当前IT从业人员的青睐。Mongo DB很好的实现了面向对象的思想,在Mongo DB中,每一条记录都是一个Document对象。Mongo DB最大的优势在于所有的数据持久操作都无需开发人员
Mongo DB是目前在IT行业非常流行的一种非关系型数据库(NoSql),其灵活的数据存储方式,备受当前IT从业人员的青睐。Mongo DB很好的实现了面向对象的思想,在Mongo DB中,每一条记录都是一个Document对象。Mongo DB最大的优势在于所有的数据持久操作都无需开发人员手动编写SQL语句,直接调用方法就可以轻松的实现CRUD操作。在这里介绍一下mongodb的安装方法:1、检查是否安装过mongodb,如已安装,则删除
# rpm -qa | grep mongodb
2、下载mongodb(下载到/doiido/soft)
# mkdir /doiido/soft
# wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-2.6.5.tgz -P /doiido/soft
3、解压缩mongodb
# cd /doiido/soft
# tar zxvf mongodb-linux-x86_64-2.6.5.tgz
# mv mongodb-linux-x86_64-2.6.5 /doiido/mongodb
4、建立数据库和日志的存储目录
# mkdir /doiido/mongodb/data
# mkdir /doiido/mongodb/logs
# touch /doiido/mongodb/logs/mongodb.log
5、建立配置文件
# vi /doiido/mongodb/bin/mongodb.conf
dbpath=/doiido/mongodb/data
logpath=/doiido/mongodb/logs/mongodb.log
port=27017
fork=true
nohttpinterface=true
6、启动mongodb
# /doiido/mongodb/bin/mongod --bind_ip localhost -f /doiido/mongodb/bin/mongodb.conf
7、设置开机启动
# echo "/doiido/mongodb/bin/mongod --config /doiido/mongodb/bin/mongodb.conf" >> /etc/rc.local
8、测试
8.1、进入mongodb的shell模式
# /doiido/mongodb/bin/mongo
8.2、查看数据库列表
> show dbs
8.3、当前db版本
> db.version();
9、停止mongodb
9.1、进入mongodb关闭
# /doiido/mongodb/bin/mongo
> db.shutdownServer();
9.2、使用mongodb指令关闭
# mongod --shutdown --config /doiido/mongodb/bin/mongodb.conf
9.3、使用kill指令
# ps -ef|grep mongo
# kill pid
注意:这个地方不能使用kill -9 pid,这样会导致数据丢失,同时mongodb还可能会报错。如果使用kill -9 pid的方式关闭mongodb,并且mongodb不能正常启动,则需删除mongod.lock文件:
# rm -f /doiido/mongodb/data/mongod.lock
# /doiido/mongodb/bin/mongod --config /doiido/mongodb/bin/mongodb.conf

Optimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata. These methods can effectively improve performance by combining monitoring, caching and data sharding in actual applications.

Mastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.

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.
