cd redis-6.2.6 Make sudo make install

- Copy the configuration file:
Copy the Redis sample configuration file to /etc/redis directory and rename it to 6379.conf (or other name you selected):
sudo cp redis.conf /etc/redis/6379.conf
- Edit configuration file:
Use a text editor (such as vi or nano ) to edit the configuration file /etc/redis/6379.conf , modify the following parameters:
-
bind 0.0.0.0: All IP addresses are allowed to connect (please be careful when setting the production environment, it is recommended to bind specific IP addresses). -
daemonize yes: Run in daemon mode. -
requirepass your_strong_password: Set the Redis access password, please replaceyour_strong_passwordwith a strong password. -
port 6379: Redis listening port, can be modified as needed. -
pidfile /var/run/redis_6379.pid: Redis process ID file path. -
logfile /var/log/redis_6379.log: Redis log file path. -
dir /var/lib/redis: Redis data storage directory.
Step 6: Start Redis
Start the Redis service using the configuration file:
redis-server /etc/redis/6379.conf
Step 7: Set Redis Start-up Self-Start
- Copy the startup script:
Copy the startup script from the Redis source package to the /etc/init.d/ directory:
sudo cp /usr/local/src/redis-6.2.6/utils/redis_init_script /etc/init.d/redis ``` (Please adjust according to the actual path) 2. **Set script permissions: ** ```bash sudo chmod x /etc/init.d/redis
- Added boot boot:
sudo chkconfig --add redis sudo chkconfig redis on
Step 8: Test Redis
Use redis-cli command line tool to test whether Redis is running normally:
redis-cli ping
If PONG is returned, it means that Redis has been installed and run successfully.
Note: The Redis version number 6.2.6 in the above steps is only an example, please adjust it according to the actual downloaded version. In production environments, be sure to carefully configure security options, such as binding a specific IP address and using a strong password. It is recommended to back up Redis data regularly.
