Redis简介

Redis是一种开放源代码（BSD许可）的内存中数据结构存储，用作数据库，缓存和消息代理。Redis提供数据结构，例如字符串，哈希，列表，集合，带范围查询的排序集合，位图，超日志，地理空间索引和流。Redis具有内置的复制，Lua脚本，LRU驱逐，事务和不同级别的磁盘持久性，并通过Redis Sentinel和Redis Cluster自动分区提供了高可用性。

官方安装教程

编译环境安装

Redis由C/C++编写，因此由源码编译成可执行程序需要C/C++编译器以及Make工具链

编译安装

root@DESKTOP:/usr/local/src/REDIS# ls
redis-6.2.3.tar.gz
root@DESKTOP:/usr/local/src/REDIS# tar -xvf redis-6.2.3.tar.gz    #解压缩
root@DESKTOP:/usr/local/src/REDIS# cd redis-6.2.3/
root@DESKTOP:/usr/local/src/REDIS/redis-6.2.3# make	 			  #编译Redis
root@DESKTOP:/usr/local/src/REDIS/redis-6.2.3# make install redis-server redis-cli redis-benchmark #安装至指定目录
复制代码

自定义配置文件

#创建配置目录
root@DESKTOP:/usr/local/src/REDIS/redis-6.2.3# mkdir MYCONF
#复制/redis-6.2.3/redis.conf Redis服务端配置文件 至MYCONF目录下
root@DESKTOP:/usr/local/src/REDIS/redis-6.2.3# cp redis.conf MYCONF/
复制代码

修改配置文件

root@DESKTOP:/usr/local/src/REDIS/redis-6.2.3# cd MYCONF/
root@DESKTOP:/usr/local/src/REDIS/redis-6.2.3/MYCONF# vim redis.conf
复制代码

Redis默认非后台启动，而通常情况下希望它能后台启动，则修改如下：

daemonize no
#修改为
daemonize yes
复制代码

Redis默认是没有登录密码的，官方将密码配置部分注释起来了，而考虑到安全问题添加相应的密码：

#requirepass foobared
#修改为
requirepass wsharkcoder
#其中密码：wsharkcoder

### Redis服务器启动

``` shell
#启动方式：redis-server <配置文件>
root@DESKTOP:/usr/local/src/REDIS/redis-6.2.3/MYCONF# redis-server /usr/local/src/REDIS/redis-6.2.3/MYCONF/redis.conf
#检查进程是否启动
root@DESKTOP:/usr/local/src/REDIS/redis-6.2.3/MYCONF# ps -ef |grep -e redis
root     16388 11797  0 18:33 ?        00:00:00 redis-server 127.0.0.1:6379
复制代码

Redis内置客户端连接Redis服务器

#连接方式:redis-cli -h <主机> -p <端口> -a <密码>
redis-cli -h localhost -p 6379 -a wsharkcoder
root@DESKTOP:/usr/local/src/REDIS/redis-6.2.3/MYCONF# redis-cli -h localhost -p 6379 -a wsharkcoder
#不安全性
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.
localhost:6379>
复制代码

关闭Redis

#Redis-cli连接后可使用shutdown进行关闭
localhost:6379> shutdown
not connected>
root@DESKTOP:/usr/local/src/REDIS/redis-6.2.3/MYCONF# ps -ef |grep -e redis
root     17824 11798  0 18:41 pts/0    00:00:00 grep --color=auto -e redis
复制代码

启动脚本

#简单脚本启动
root@DESKTOP:/usr/local/src/REDIS/redis-6.2.3# touch Start_Redis.sh			#创建启动脚本
root@DESKTOP:/usr/local/src/REDIS/redis-6.2.3# vim Start_Redis.sh           #编辑启动脚本
root@DESKTOP:/usr/local/src/REDIS/redis-6.2.3# cat Start_Redis.sh           #查看启动脚本内容
#!/bin/bash
redis-server ./MYCONF/redis.conf
root@DESKTOP:/usr/local/src/REDIS/redis-6.2.3# chmod u+x Start_Redis.sh     #赋予启动脚本执行权限
root@DESKTOP:/usr/local/src/REDIS/redis-6.2.3# ./Start_Redis.sh				#脚本启动
root@DESKTOP:/usr/local/src/REDIS/redis-6.2.3# ps -ef |grep -e redis        #检索进程
root     19201 11797  0 18:48 ?        00:00:00 redis-server 127.0.0.1:6379
root     19228 11798  0 18:48 pts/0    00:00:00 grep --color=auto -e redis
