Review of NoSQL and Redis Five Jobs

1. Assignment 1

Requirements:
Install CentOS Linux system on VM, install C++ compiler through yum on Linux, and compile and install Redis.

Observe the Redis directory structure, use redis-server to start the server, use front-end mode and back-end mode to start respectively
Take screenshots of the running commands, server status, logs and other information, organize them into word, and submit the word file.

1. The command to run:

[souranker@localhost ~]$ su root
[root@localhost souranker]# cd root
[root@localhost souranker]# tar -zxvf redis-3.0.7.tar.gz
[root@localhost souranker]# cd redis-3.0.7
[root@localhost redis-3.0.7]# yum install gcc-c++ -y
[root@localhost redis-3.0.7]# make
[root@localhost redis-3.0.7]# make install
[root@localhost redis-3.0.7]# cd /usr/local/bin
[root@localhost redis-3.0.7]# redis-server
[root@localhost redis-3.0.7]# cp redis.conf /usr/local/bin
[root@localhost redis-3.0.7]# cd /usr/local/bin
[root@localhost redis-3.0.7]# vim redis.conf
[root@localhost redis-3.0.7]# redis-server ./redis.conf
[root@localhost redis-3.0.7]# ps -ef | grep redis

2. Assignment 2

Require:

1. Create multiple redis.conf files, modify the port number, start multiple redis servers, and use ps to observe the server process.
2. Implement the following operations in redis:
   1) Delete all data in the existing warehouse
   2) Switch to the database numbered 2
   3) Add new key-value pairs to store student number, name, age, and gender respectively
   4) Switch to the database numbered 3 get the database, use the hash method to store the student object, save the student number, name, age, gender information
   5) switch to the number 4 database, use the list method to store the student number, name, age, gender information
   6) respectively in the 234 database Add email data and delete gender information
3. Take screenshots of the running commands, server status, logs and other information, organize them into word, and submit the word file.

3. Assignment 3

Implement the following operations in java:
1.String type
1) Delete all data in the existing warehouse
2) Switch to the database numbered 0
3) Add key-value pairs to store student number, name, age, gender respectively

2. Hash type
1) Switch to the database numbered 1, use the hash method to store the student object, save the student number, name, age, gender information 2) the
console prints the field name and field value separately
3) delete the gender information

3. List type
1) Switch to the database numbered 2, use the list method to store student number, name, age, gender information, and print it on the console 2) Add
mailbox information before gender information
3) Delete gender information

4. Assignment 4

Implement the following functions through Java code

1. Use the set type to implement the following operations in redis:
   1) Add the grades of 3 classes, each class uses a set description, and the key is the class number
   2) Check all the unique grades in the 3 classes
   3) Compare the first and the first For the results of the second class, check the difference between the second class and the first class.
   4) Take screenshots of the running commands, server status, logs and other information, organize them into word, and submit the word file.

2. Use the zset type to achieve the following operations:
1) Store user names and points
2) Arrange the names of all users according to the points from high to low
3) View the ranking of users whose name is tom
4) View all users with points within 1000-5000
5) Take screenshots of the running commands, server status, logs and other information, organize them into word, and submit the word file.

5. Assignment 5

1. Use mybatis to connect to the mysql database and debug successfully
2. Configure and implement redis instead of mybatis secondary cache
3. Implement redis to automatically cache mysql data and test
