How to install redis in CentOS7 and configure it to be accessible from the external network
1. Install gcc editor
Installing redis needs to rely on the gcc environment. Execute the following command to install:
yum install -y gcc
If the machine does not have a network, you can refer to this article:
CentOS offline installation gcc environment (with installation package pictures and texts)
2. Download the redis installation package
redis official website: https://redis.io/download
Download Then upload it to CentOS, for example, upload it to /usr/local/
3, decompress and compile and install redis
command is as follows:
1, Enter the installation package directory
cd /usr/local/
2. Unzip the installation package
tar -zxvf redis-6.2.1.tar.gz
3. Enter the decompressed redis directory and compile
cd redis-6.2.1 make
/usr/local/redis as an example:
make install prefix=/usr/local/redis
cd /usr/local/redis/binAt this time, just execute the following command to start:
./redis-serverThe startup screenshot is as follows:
find / -name 'redis.conf'The results are as follows:
cp /usr/local/redis-6.2.1/redis.conf /usr/local/redis/bin/Then modify the thread mode parameters of the redis.conf configuration file:
vi /usr/local/redis/bin/redis.confPS: vi shortcut key, click
/, and then enter [keyword] Query parameters.
daemonizeThe corresponding value is yes
1、修改之前 daemonize no 2、修改之后 daemonize yesExplanation of the value of this parameter:
- yes: redis The single-process multi-thread mode is adopted. Turning on daemon mode means when the daemonize option in the redis.conf file is set to "yes". In this mode, redis will run in the background and write the process pid number to the file set by the redis.conf option pidfile. At this time, redis will always run unless the process is manually killed.
- no: When the daemonize option is set to no, the current interface will enter the redis command line interface. Exit force exit or closing the connection tool (putty, xshell, etc.) will cause the redis process to exit. .
./redis-server redis.confNow redis is started in the background. 5. Set external network accessThe default configuration file does not support external network access. Next, modify the parameters for external network access. Or modify the configuration file:
vi /usr/local/redis/bin/redis.confFind the following three parameters:
- ##bind 127.0.0.1 (bind the IP that allows access)
- protected-mode yes (protected mode on)
- #requirepass yourpassword (request access password)
- The first and second items are combination items, which are particularly important. The third item is to set a password, which protects the service area to a certain extent.
is modified as follows:
- bind 127.0.0.1
- ##protected-mode no
- requirepass Your password
- After modification, save and exit.
vi /etc/systemd/system/redis.serviceAdd the following command:
[Unit] Description=redis-server After=network.target [Service] Type=forking ExecStart=/usr/local/redis/bin/redis-server /usr/local/redis/bin/redis.conf PrivateTmp=true [Install] WantedBy=multi-user.targetThe ExecStart parameter corresponds to the installation of redis-server in the Redis directory, and the configuration file is the same as above. Set up startup:
systemctl daemon-reload systemctl start redis.service systemctl enable redis.service7. Common service commandsStart redis service
systemctl start redis.service
Stop redis servicesystemctl stop redis.service
Restart Start the servicesystemctl restart redis.service
View the current status of the servicesystemctl status redis.service
Set auto-start at bootsystemctl enable redis.service
Stop auto-start at bootsystemctl disable redis.service

Redis improves application performance and scalability by caching data, implementing distributed locking and data persistence. 1) Cache data: Use Redis to cache frequently accessed data to improve data access speed. 2) Distributed lock: Use Redis to implement distributed locks to ensure the security of operation in a distributed environment. 3) Data persistence: Ensure data security through RDB and AOF mechanisms to prevent data loss.

Redis's data model and structure include five main types: 1. String: used to store text or binary data, and supports atomic operations. 2. List: Ordered elements collection, suitable for queues and stacks. 3. Set: Unordered unique elements set, supporting set operation. 4. Ordered Set (SortedSet): A unique set of elements with scores, suitable for rankings. 5. Hash table (Hash): a collection of key-value pairs, suitable for storing objects.

Redis's database methods include in-memory databases and key-value storage. 1) Redis stores data in memory, and reads and writes fast. 2) It uses key-value pairs to store data, supports complex data structures such as lists, collections, hash tables and ordered collections, suitable for caches and NoSQL databases.

Redis is a powerful database solution because it provides fast performance, rich data structures, high availability and scalability, persistence capabilities, and a wide range of ecosystem support. 1) Extremely fast performance: Redis's data is stored in memory and has extremely fast read and write speeds, suitable for high concurrency and low latency applications. 2) Rich data structure: supports multiple data types, such as lists, collections, etc., which are suitable for a variety of scenarios. 3) High availability and scalability: supports master-slave replication and cluster mode to achieve high availability and horizontal scalability. 4) Persistence and data security: Data persistence is achieved through RDB and AOF to ensure data integrity and reliability. 5) Wide ecosystem and community support: with a huge ecosystem and active community,

Key features of Redis include speed, flexibility and rich data structure support. 1) Speed: Redis is an in-memory database, and read and write operations are almost instantaneous, suitable for cache and session management. 2) Flexibility: Supports multiple data structures, such as strings, lists, collections, etc., which are suitable for complex data processing. 3) Data structure support: provides strings, lists, collections, hash tables, etc., which are suitable for different business needs.

The core function of Redis is a high-performance in-memory data storage and processing system. 1) High-speed data access: Redis stores data in memory and provides microsecond-level read and write speed. 2) Rich data structure: supports strings, lists, collections, etc., and adapts to a variety of application scenarios. 3) Persistence: Persist data to disk through RDB and AOF. 4) Publish subscription: Can be used in message queues or real-time communication systems.

Redis supports a variety of data structures, including: 1. String, suitable for storing single-value data; 2. List, suitable for queues and stacks; 3. Set, used for storing non-duplicate data; 4. Ordered Set, suitable for ranking lists and priority queues; 5. Hash table, suitable for storing object or structured data.

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.
