本文介绍了在AWS中redis的下载以及相关的配置

一.从官网下载redis.

下载文件名为:redis-4.0.9.tar.gz

二.将下载的redis文件上传AWS.

1.通过SCP上传redis-4.0.9.tar.gz文件

1
scp -i /Users/lby/key.pem -r /Users/lby/Desktop/AWS文件/redis-4.0.9.tar.gz ec2-user@123.123.123.1523:/data

以上命令表示:将redis-4.0.9.tar.gz文件上传至服务器/data文件夹下.

三.解压redis-4.0.9.tar.gz文件并修改文件名.

解压文件命令如下:

1
tar -zxvf redis-4.0.9.tar.gz

此时当前路径下的文件名为redis-4.0.9.如果需修改文件名,使用以下命令:

1
mv redis-4.0.9 redis

命令含义为:mv 原文件名 修改后文件名

四.redis配置.

1.进入redis文件中.

1
cd /data/redis

2.执行make命令.

1
make

如果出现以下错误:

make[1]: Leaving directory `/data/installfiles/redis-4.0.9/src'
make: *** [test] Error 2

根据gcc: Command not found提示可知,缺少gcc,那就安装gcc.
通过yum安装gcc的命令:

1
sudo yum install gcc

执行成功后显示:

Complete!

3.执行make test命令.

1
make test

compilation terminated.
make[1]: *** [adlist.o] Error 1
make[1]: Leaving directory `/data/installfiles/redis-4.0.9/src’

根据zmalloc.h:50:31: fatal error: jemalloc/jemalloc.h: No such file or directory提示可使用以下命令解决:

1
make MALLOC=libc

显示

1
Hint: It's a good idea to run 'make test' ;)

4.重新执行make test命令

1
make test

5.执行make install命令

1
make install

6.进入redis下的src文件.

1
cd src

7.开启redis服务

1
./redis-server

如果以下信息表示redis服务开启成功.

8.查看redis是否开启

1
./redis-cli

显示:

1
127.0.0.1:6379>

输入

1
ping

显示:pong,表示,redis服务可以使用.
也可以输入keys *查看redis缓存中的所有key.

1
keys *

五.redis自启动配置.

1.进入redis文件

1
cd /data/redis

2.将redis.conf文件复制到etc文件目录下

1
cp redis.conf /etc

3.进入etc文件

1
cd /etc

此时,etc文件下已经有redis.conf文件.

4.修改redis.conf文件中的daemonize no参数为daemonize yes.

1
vim redis.conf

输入i进入编辑状态.

1
i

找到daemonize no参数,改为daemonize yes.
强制写入保存并退出

1
:wq!

5.使配置生效.

1
redis-server /etc/redis.conf

最终显示:

6691:C 23 May 06:59:02.250 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
6691:C 23 May 06:59:02.250 # Redis version=4.0.9, bits=64, commit=00000000, modified=0, pid=6691, just started
6691:C 23 May 06:59:02.250 # Configuration loaded

总结:到此,AWS中的redis配置就告一段落.
