这里redis打开之后好像在文档编辑的模式，无法退出，我点击CTRL+c强行退出的话，又会导致redis关闭，从而查找不到redis的进程。这种情况怎么办嘞？

同学你好，当前redis是前台运行，再开一个会话窗口查询试下。例如：
同学也可退出redis前台运行，按照当前小节课程步骤设置redis后台运行后 再查询redis进程。
注：设置后台运行时需先将redis.conf中的daemonize设置为yes
若未修改，redis.conf中的daemonize默认设置为no，使用命令systemctl start redis启动后redis仍是前台运行，exit强制退出或者关闭连接工具都会导致redis进程退出；将daemonize设置为yes，使用命令systemctl start redis启动，此时redis才为后台运行。
祝学习愉快~
