CentOS 7 安装Redis 2.8.7详解大数据

1、下载软件：

wget wget http://download.redis.io/releases/redis-2.8.7.tar.gz

2、解压软件并编译安装:

tar -zxvf redis-2.8.7.tar.gz

mv redis-2.8.7.tar.gz redis

cd redis

make make install

等待编译一端时间即可(如果您的机器上没有c++编译环境，可以通过yum安装 gcc ，命令：yum -y install gcc)

cd src

启动redis-server：./redis-server  ../redis.conf

启动会发送警告:

[16403] 12 Dec 21:55:32.830 # WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add vm.overcommit_memory = 1 to /etc/sysctl.conf and then reboot or run the command sysctl vm.overcommit_memory=1 for this to take effect.

安装提示，解决上述问题。默认的情况下，redis监听6379端口。

3、测试使用redis  #使用 telnet 

[[email protected] local]$ telnet localhost 6379 

Trying ::1... 

Connected to localhost. 

Escape character is ^]. 

set likehua likehua 

get likehua 

likehua 

  4、使用redis-benchmark对redis可以进行简单的性能测试。

 1 [[email protected] src]$ ./redis-benchmark -h localhost -p 6379 -c 1000 -n 100000
