Docker installation Redis instance analysis
1. Start docker
systemctl start docker
2. Pull the redis image
docker pull redis:5.0.3
Note that if the version number is not specified, pull the latest version
3. Create a local redis mounting directory
mkdir -p /root/redis/data /root/redis/conf
4. Create a redis.conf file
touch /root/redis/data /root/redis/conf/redis.conf
5. Modify the redis.conf file
Download link: https: //www.lanzous.com/i68hlah
This configuration file can be downloaded online at http://download.redis.io/releases/, and the following configurations are mainly modified.
Before modification:
bind 127.0.0.1 protected-mode yes #requirepass yourpassword
After modification:
#bind 127.0.0.1 protected-mode no requirepass yourpassword
where yourpassword is your password .
6. Create a redis container
docker run -d --name redis -p 6379:6379 -v /root/redis/conf/redis.conf:/redis.conf -v /root/redis/data:/data redis:5.0.3 redis-server --appendonly yes
-d Run in the background
-p Map the port to the host's port
-v Mount the host directory to the container's directory
redis-server --appendonly yes: Execute the redis-server startup command in the container and open the redis persistence configuration
7. Start the created redis container
docker start redis
If you execute the above command and the following error is reported:
Error response from daemon: driver failed programming external connectivity on endpoint redis (086c7fdf5eb7a696753d7414e93202eefd474370658e8c090bca5608c6e29a11): (iptables failed: iptables --wait -t nat -A DOCKER -p tcp -d 0/0 --dport 6379 -j DNAT --to-destination 172.17.0.2:6379 ! -i docker0: iptables: No chain/target/match by that name. (exit status 1)) Error: failed to start containers: redis
Solution: Restart docker, and then restart the redis container
systemctl restart docker docker start redis
8. Open firewall port 6379
firewall-cmd --zone=public --add-port=6379/tcp --permanent firewall-cmd --reload
9. Local connection test
10. Connection error
If the connection fails, first check whether you can log in to redis on the server
docker exec -it redis redis-cli
Enter the following command after entering redis:
auth "你的密码"
If prompted:
(error) ERR Client sent AUTH, but no password is set
Indicates our settings The password does not take effect, then you need to execute the following command again:
config set requirepass “你的密码”
