CentOS7下安装Redis

1.安装Redis

第一步：跳转到local目录

cd /usr/local/

第二步：下载redis安装包

wget http://download.redis.io/releases/redis-4.0.6.tar.gz

第三步：解压压缩包

tar -zxvf redis-4.0.6.tar.gz

第四步：yum安装gcc依赖

yum install gcc

第五步：跳转到redis解压目录下

cd redis-4.0.6

第六步：编译安装

make MALLOC=libc

将/usr/local/redis-4.0.6/src目录下的文件加到/usr/local/bin目录

cd src && make install

第七步：测试是否安装成功 

先切换到redis src目录下

cd src

1、直接启动redis

./redis-server

如上图：redis启动成功，但是这种启动方式需要一直打开窗口，不能进行其他操作，不太方便。

按 ctrl + c可以关闭窗口。
