一,下載及安裝
redis 官網下載地址 https://redis.io/download
我的redis安裝目錄是/data/program/redis-4.0.11
$ wget http://download.redis.io/releases/redis-2.8.3.tar.gz $ tar xzf redis-2.8.3.tar.gz $ cd redis-2.8.3 $ make
安裝過程可能出現的問題: 1. linux 中沒有安裝gcc包,通過下面命令安裝: $ yum -y install gcc 2.make時報如下錯誤: zmalloc.h:50:31: fatal error: jemalloc/jemalloc.h: No such file or directory 原因是jemalloc重載了Linux下的ANSI C的malloc和free函數。解決辦法:make時添加參數。 $ make MALLOC=libc
啓動服務

二,修改配置
表示安裝成功. redis 的進程id爲 10558,端口爲 6379.
但是這樣啓動不是很方便,啓動服務端的窗口不能關閉,一旦關閉服務自動停止...
修改 reids.conf 文件
將daemonize參數的值由no改爲yes,系統默認是no.保存退出,指定配置文件啓動
$ ./redis-server redis.conf
三,配置全局命令
創建redis的命令目錄
$ mkdir /data/program/redis-4.0.11/bin
將腳本目錄複製到命令目錄中
$ cp redis-cli redis-server redis-sentinel redis-check-aof redis-benchmark /data/program/redis-4.0.11/bin/
配置環境變量
$ vim /etc/profile (在文件末尾加入)
export PATH=$PATH:/data/program/redis-4.0.11/bin
$ source /etc/profile (使環境變量生效)
$ redis-server (任意目錄下都可以使用該命令啓動)
