搭建redis服务

首先拉取镜像==》运行镜像为容器

# 先搜索下redis镜像

[root@VM_0_10_centos wordpress]# docker search redis

# 拉取镜像（不接版本，默认拉取最新版本）

[root@VM_0_10_centos wordpress]# docker pull redis

Using default tag: latest

latest: Pulling from library/redis

运行容器

# 运行容器，外部端口6378 内部端口6379

[root@VM_0_10_centos wordpress]# docker run -itd -p 6378:6379 --name redis redis

# 查看容器

[root@VM_0_10_centos wordpress]# docker ps

CONTAINER ID        IMAGE                     COMMAND                  CREATED             STATUS              PORTS

                           NAMES6a9eef9b4fde        redis                     "docker-entrypoint.s…"   2 minutes ago       Up 2 minutes        0.0.0.0:6378

->6379/tcp

进入容器查看

[root@VM_0_10_centos wordpress]# docker exec -it redis bash

root@6a9eef9b4fde:/data# redis-cli

127.0.0.1:6379> ls

进行测试。redis是以键值对方式存数据的（redis默认有16个数据库，0-15）

root@6a9eef9b4fde:/data# redis-cli

127.0.0.1:6379> set color green  # 设置键值对

OK

127.0.0.1:6379> get color　　# 通过键获取值

"green"
127.0.0.1:6379> keys *　　# 获取键列表
1) "color"
