Redis

安装Redis环境

要在 Ubuntu 上安装 Redis，打开终端，然后输入以下命令：

$sudo apt-get update
$sudo apt-get install redis-server

这将在您的计算机上安装Redis

启动 Redis

$redis-server

查看 redis 是否还在运行

$redis-cli

这将打开一个 Redis 提示符，如下图所示：

redis 127.0.0.1:6379>

在上面的提示信息中：127.0.0.1 是本机的IP地址，6379是 Redis 服务器运行的端口。现在输入 PING 命令，如下图所示：

redis 127.0.0.1:6379> ping
PONG

这说明现在你已经成功地在计算机上安装了 Redis。
