apt-get、yum、homebrew 这些包管理工具为我们安装软件带来许多便利,然而也有一些弊端:

  • 不同的包管理工具规则不一,比如安装路径、配置文件路径、启动方式不同;而很多情况下,开发者对包管理工具只是停留在使用的级别,并不能完全掌握各工具的规则;于是就会导致软件扩展不便
  • 另一方面,软件包版本问题:软件官方一般可以提供最新版本,包管理工具的镜像源存在一些滞后,于是有时候未必能下载到开发者所需要的版本。

于是,为了使各大规则可控,有时候需要使用手动安装的方式;为了方便 Redis 的相关扩展(如新建端口),下面采取手动安装的方式。

## 下载并编译
## 截止到 2018-07-13,最新版本为 v4.0.10
wget http://download.redis.io/redis-stable.tar.gz
tar xvzf redis-stable.tar.gz
cd redis-stable
make

## Redis 的核心文件就这两个
cp src/redis-server /usr/local/bin/
cp src/redis-cli /usr/local/bin/

## 此目录用于保存 6379 端口相关的各类文件
mkdir -p /usr/local/etc/redis/6379

## 端口6379的配置文件
cp redis.conf /usr/local/etc/redis/6379/redis.conf

## =================================== ##
## 编辑配置文件
vi /usr/local/etc/redis/6379/redis.conf

#### 修改以下字段 ####
port => 6379
daemonize => yes
pidfile => /usr/local/etc/redis/6379/redis.pid
logfile => /usr/local/etc/redis/6379/redis.log
dir => /usr/local/etc/redis/6379

#### 考虑安全性,添加以下记录 ####
rename-command FLUSHALL ""
rename-command FLUSHDB ""
rename-command CONFIG ""
rename-command EVAL ""
## =================================== ##
