docker pull redis:3.2

查看镜像

[root@seven ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE

创建并运行容器

docker run -p 6379:6379 --name redis_ian --restart=always -v /root/docker/redis/data:/data  -d redis:3.2 redis-server --appendonly yes

参数说明：

• -p 6379:6379：指定暴露的端口
• --name redis_ian：为容器设置名称
• -v /root/docker/redis/data:/data：将主机中/root/docker/redis/data目录挂载到容器的/data目录
  -d 后台启动

1:M 27 Apr 12:03:10.013 # 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.
