redis，如何配置密码，端口号，keep-alive时长

如果不配置keep-alive，有可能会掉线，用着用着，就会有那个远程主机关闭链接的提示。

创建一个redis的目录

在里面创建redis.conf，docker-compose.yaml文件

配置文件redis.conf

tcp-keepalive 0
requirepass 123456
port 6389

• tcp-keepalive 为0表示不限制
• requirepass 为密码
• port 为端口

保存为redos.conf文件

docker-compse.yaml文件

version: '3.3'
services:
    redis:
      restart: always
      image: redis:6.0.5
      container_name: redis-container
      ports:
        - "16379:6389"
      volumes:
        - ./data:/data
        - /etc/timezone:/etc/timezone
        - /etc/localtime:/etc/localtime
        - ./redis.conf:/usr/local/etc/redis/redis.conf
      command: ["redis-server", "/usr/local/etc/redis/redis.conf"]

保存为docker-compose.yaml文件

创建容器

docker-compose up -d

查看日志

docker-compose logs

如果日志里的端口号和你的一样，那么就是配置生效了。

警告处理

 WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
redis-master | 1:M 19 Apr 2024 14:17:34.336 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.

• add 'vm.overcommit_memory = 1' to /etc/sysctl.conf
• echo never > /sys/kernel/mm/transparent_hugepage/enabled
• add it to your /etc/rc.local
