Mac Install Redis

目标

1、安装并启动Redis
2、熟悉配置文件
3、关闭Redis

环境（ sw_vers命令）

ProductName: Mac OS X
ProductVersion: 10.13.6
BuildVersion: 17G65
RedisVersion: 4.0.9

安装

方式一：官网下载并本地编译，移步https://blog.csdn.net/jason_m_ho/article/details/80007330
方式二：使用brew安装（这里使用此种方式）

1、执行安装命令

brew install -v redis

安装成功

2、查看配置文件
默认配置文件：
/usr/local/etc/redis.conf
/usr/local/etc/redis-sentinel.conf
BD目录:
/usr/local/var/db/redis/dump.rdb

官网上对于如何配置redis的描述:
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.

意思是：
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

1、修改默认配置文件:/usr/local/etc/redis.conf

bind 127.0.0.1 ::1
bind 127.0.0.1
port 6379
tcp-backlog 511
timeout 0
tcp-keepalive 300

2、执行启动命令：

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

3、启动成功

➜  ~ redis-server /usr/local/etc/redis.conf

4、检测redis服务器是否启动

重新打开一个终端窗口，输入命令
$ redis-cli ping
该终端输出 pong
说明服务器运作正常。

关闭Redis

方式一：
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
然后在另外一个终端窗口执行
$ redis-cli ping
输出
Could not connect to Redis at 127.0.0.1:6379: Connection refused
说明确实已关闭

方式二：
在另外一个终端窗口执行$ redis-cli shutdown,此时第一个窗口输出

5079:M 01 Sep 22:33:45.757 # User requested shutdown...
5079:M 01 Sep 22:33:45.757 * Saving the final RDB snapshot before exiting.
5079:M 01 Sep 22:33:45.757 * DB saved on disk
5079:M 01 Sep 22:33:45.757 * Removing the pid file.
5079:M 01 Sep 22:33:45.757 # Redis is now ready to exit, bye bye...
