==> make install PREFIX=/usr/local/Cellar/redis/3.2.3 CC=clang
==> Caveats
To have launchd start redis now and restart at login:
  brew services start redis
Or, if you don't want/need a background service you can just run:
  redis-server /usr/local/etc/redis.conf
==> Summary
🍺  /usr/local/Cellar/redis/3.2.3: 10 files, 1.7M, built in 21 seconds

从以上日志输出可以看出，如果需要给redis服务端指定配置文件，
启动命令应该是这样的:

1
$ redis-server /usr/local/etc/redis.conf

配置文件

安装完成后redis默认的配置文件redis.conf位于

1
/usr/local/etc

同时，redis-sentinel.conf也在这里。

使用cat命令查看redis.conf：

1
$ cat /usr/local/etc/redis.conf

终端输出文件内容（删掉了大部分注释）：

官网上对于如何配置redis的描述:

1
2
Redis is able to start without a configuration file using a built-in default configuration, however this setup is only recommended for testing and development purposes.
The proper way to configure Redis is by providing a Redis configuration file, usually called redis.conf.

根据以上内容,如果启动时不指定配置文件,redis会使用程序中内置的默认配置.但是只有在开发和测试阶段才考虑使用内置的默认配置，正式环境最好还是提供配置文件，并且一般命名为redis.conf

启动redis

可以通过以下命令启动redis：

1
$ redis-server /usr/local/etc/redis.conf

终端输出

8568:M 11 Sep 21:37:46.844 # Server started, Redis version 3.2.3
8568:M 11 Sep 21:37:46.845 * The server is now ready to accept connections on port 6379

可以看出redis服务器启动成功，并在监听6379端口的网络连接。
注意: 使用命令$ redis-server也可以启动,此时并不会加载任何配置文件,使用的是程序中内置(built-in)的默认配置.

检测redis服务器是否启动
重新打开一个终端窗口，输入命令

1
$ redis-cli ping

该终端输出

1
pong

说明服务器运作正常。

关闭redis

关闭redis有2种方法：

  • 方法1
    在执行启动命令的终端窗口使用ctrl+c,此时第一个窗口输出

8773:M 11 Sep 21:46:26.581 * Saving the final RDB snapshot before exiting.
8773:M 11 Sep 21:46:26.583 * DB saved on disk
8773:M 11 Sep 21:46:26.583 * Removing the pid file.
8773:M 11 Sep 21:46:26.583 # Redis is now ready to exit, bye bye...

然后在另外一个终端窗口执行$ redis-cli ping,输出

1
Could not connect to Redis at 127.0.0.1:6379: Connection refused

说明确实已关闭

  • 方法2
    在另外一个终端窗口执行$ redis-cli shutdown,此时第一个窗口输出
