Mac上安装Redis

redis安装有两种方式：下载源码编译安装、使用homebrew安装。

通过homebrew安装redis

1 2	brew install redis

配置文件

安装完成后redis默认的配置文件redis.conf位于

/usr/local/etc

同时，redis-sentinel.conf也在这里。

使用cat命令查看redis.conf：

1 2	cat /usr/local/etc/redis.conf

包含以下内容(删除了大部分内容)：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

# started with the file path as first argument: # # ./redis-server /path/to/redis.conf # Accept connections on the specified port, default is 6379 (IANA #815344). # If port 0 is specified Redis will not listen on a TCP socket. port 6379 # TCP listen() backlog. tcp-backlog 511 #The working directory dir /usr/local/var/db/redis/

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-server

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

终端输出

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48

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.

检查redis服务是否启动

重新打开一个终端窗口，输入命令

1 2	redis-cli ping

该终端输出

1 2

PONG

说明服务器运作正常。

关闭redis

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

1 2 3 4 5 6 7 8 9 10 11 12 13 14

^C46286:signal-handler (1551325146) Received SIGINT scheduling shutdown... 46286:M 28 Feb 2019 11:39:06.432 # User requested shutdown... 46286:M 28 Feb 2019 11:39:06.432 * Saving the final RDB snapshot before exiting. 46286:M 28 Feb 2019 11:39:06.434 * DB saved on disk 46286:M 28 Feb 2019 11:39:06.434 * Removing the pid file. 46286:M 28 Feb 2019 11:39:06.434 # Redis is now ready to exit, bye bye... zhuhaijundeMacBook-Pro:redis apple$

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

1 2 3 4 5 6 7 8 9 10

46288:M 28 Feb 2019 11:40:16.348 # User requested shutdown... 46288:M 28 Feb 2019 11:40:16.348 * Saving the final RDB snapshot before exiting. 46288:M 28 Feb 2019 11:40:16.349 * DB saved on disk 46288:M 28 Feb 2019 11:40:16.349 * Removing the pid file. 46288:M 28 Feb 2019 11:40:16.349 # Redis is now ready to exit, bye bye...
