Redis Installation and Deployment

Opening Specified Ports or Disabling Firewall

1. View the ports that are already open:

   firewall-cmd --list-ports
   

2. Open a specified port (e.g., port 6379 for Redis):

   firewall-cmd --zone=public --add-port=6379/tcp --permanent
   

3. Reload the firewall configuration:

   firewall-cmd --reload
   

4. Confirm the opened ports:

   firewall-cmd --list-ports
   

5. If needed, you can stop the firewall:

   systemctl stop firewalld
   

6. Check the firewall status:

   systemctl status firewalld
   

Installation and Deployment

1. Extract the Redis installation package:

   tar -zxvf redis-4.0.9.tar.gz -C /usr/local/
   

2. Rename the extracted folder:

   mv redis-4.0.9 redis
   

3. Install the required dependencies (e.g., GCC):

   yum install gcc -y
   

4. Compile the Redis files:

   cd /usr/local/redis
   make && make install
   

Edit Configuration File

1. Edit the Redis configuration file:

   vi redis.conf
   

2. Set a password (e.g., "123456"):

   # Before
   # requirepass foobared
   
   # After
   requirepass 123456
   

3. Enable background daemon mode:

   # Before
   # daemonize no
   
   # After
   daemonize yes
   

4. Allow remote access:

   # Before
   # bind 127.0.0.1
   
   # After
   bind 0.0.0.0
   

5. Save the configuration file and exit the editor.

Start Redis

1. Start Redis using the modified configuration file:

   redis-server /usr/local/redis/redis.conf
   

2. Validate the Redis server is running:

   redis-cli
   

Make sure to adjust paths, passwords, and other configurations as needed for your specific environment.
