linux环境下安装redis

一. 官网下载redis稳定版

https://redis.io/download

二. 将下载的文件传到linux系统中,自己建立目录

我这里用的winSCP,目录是usr/local/redis
linux下创建目录命令: mkdir 目录名称

[root@iz2zeeh47kp5evidpgzz7gz /]# cd /usr/local/redis
[root@iz2zeeh47kp5evidpgzz7gz redis]# ls
redis-5.0.5.tar.gz
[root@iz2zeeh47kp5evidpgzz7gz redis]# 

三.解压redis,进入解压后的目录进行编译安装

[root@iz2zeeh47kp5evidpgzz7gz redis]# tar xzf redis-5.0.5.tar.gz
[root@iz2zeeh47kp5evidpgzz7gz redis]# ls
redis-5.0.5  redis-5.0.5.tar.gz
[root@iz2zeeh47kp5evidpgzz7gz redis]# cd redis-5.0.5
[root@iz2zeeh47kp5evidpgzz7gz redis-5.0.5]# make
[root@iz2zeeh47kp5evidpgzz7gz redis-5.0.5]# cd src
[root@iz2zeeh47kp5evidpgzz7gz src]# sudo make install

四. 启动redis服务

[root@iz2zeeh47kp5evidpgzz7gz src]# redis-server
6435:C 18 May 2019 10:19:29.457 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

服务端默认是运行在前台的,如果是用的阿里云服务器记得在安全组添加放行,默认端口是6739

五. 测试是否成功启动redis

[root@iz2zeeh47kp5evidpgzz7gz ~]# redis-cli
127.0.0.1:6379> ping
PONG
127.0.0.1:6379> set name zhangfei
OK
127.0.0.1:6379> get name
"zhangfei"
127.0.0.1:6379> del name
(integer) 1
