  内容

    bind 0.0.0.0

    # 端口

    port 6379

    # 持久化

    appendonly yes

    requirepass password

# docker run -d -ti -p 6379:6379 --net docker_default \

-v /data/redis/conf4.0/redis.conf:/usr/local/etc/redis/redis.conf \

-v /data/redis/data:/data --restart always --name redis4.0 \

--sysctl net.core.somaxconn=1024 \

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

1、-p是指启动的端口

2、第二行指定了配置的位置，命令指的是刚刚复制的配置，配置中有端口、密码等重要参数

3、第三行开始的是指定数据存储位置，--restart always是自动重启，--name redis4.0设置容器的名字为redis4.0

4、第四行设置tcp内核参数，默认512

5、启动镜像名和服务、配置（固定不能变）
