Redis安装与启动

 概述

Redis【REmote DIctionary Server】作为当前比较流行的NoSql数据库,以其高性能,高可用的的特点,应用越来越广泛,深得各大企业和开发人员的青睐,本文主要简述Redis的下载,安装,启动,关闭的整个流程,仅供学习分享使用,如有不足之处,还请指正。

什么是Redis?

Redis 是完全开源的,遵守 BSD 协议,是一个高性能的 key-value 数据库。
Redis 与其他 key - value 缓存产品有以下三个特点:
  1. Redis支持数据的持久化,可以将内存中的数据保存在磁盘中,重启的时候可以再次加载进行使用。
  2. Redis不仅仅支持简单的key-value类型的数据,同时还提供list,set,zset,hash等数据结构的存储。
  3. Redis支持数据的备份,即master-slave模式的数据备份。

Redis 优势

  • 性能极高 – Redis能读的速度是110000次/s,写的速度是81000次/s 。
  • 丰富的数据类型 – Redis支持二进制案例的 Strings, Lists, Hashes, Sets 及 Ordered Sets 数据类型操作。
  • 原子 – Redis的所有操作都是原子性的,意思就是要么成功执行要么失败完全不执行。单个操作是原子性的。多个操作也支持事务,即原子性,通过MULTI和EXEC指令包起来。
  • 丰富的特性 – Redis还支持 publish/subscribe, 通知, key 过期等等特性。

Redis安装环境

  • 操作系统:Linux CentOS 7.0 64位操作系统
  • Redis版本:稳定版 redis6.0.9

Redis下载安装包

Redis的安装包,可以到Redis官网进行下载最新稳定版本,目前的稳定版本为redis6.0.9,如下所示:

Redis安装

1. 下载安装包【redis-6.0.9.tar.gz】以后,通过Xftp工具,上传到Linux系统中 HOME/DownLoad中。然后切换到home/DownLoad 并通过 【tar -zxvf redis-6.0.9.tar.gz 】进行解压到当前目录。如下所示:

2. 通过过cp -r redis-6.0.9 /usr/local/src/redis 命令,将复制解压后的目录到/usr/local/src目录下,并修改文件夹名称为redis。如下所示:

3. 通过gcc -v命令检测gcc是否安装。如下所示:

 4. 如果没有安装,则通过yum install gcc-c++命令进行安装,如下所示:

5. gcc安装成功后,进入到/usr/local/src/redis/deps目录下,对hiredis lua jemalloc linenoise 四个进行预编译,命令为【 make hiredis lua jemalloc linenoise 】编译过程无error出现,则表示预编译成功。如下所示:

  1 [root@bogon deps]# ls
  2 hiredis  jemalloc  linenoise  lua  Makefile  README.md  update-jemalloc.sh
  3 [root@bogon deps]# make hiredis lua jemalloc linenoise
  4 MAKE hiredis

当出现如下所示,则表示编译成功,如下所示:

 6. 编译成功后,则显示如下所示:

7. 通过mkdir /usr/local/redis 命令在/usr/local目录下,创建redis文件夹。然后通过make install PREFIX=/usr/local/redis 命令进行安装redis。

 8. 安装成功后,切换到/usr/local/redis/bin目录下进行查看,存在如下所示文件则表示安装成功。

 9. 在root目录下,创建myredis文件夹,并将/usr/local/src/redis/redis.conf 文件复制到myredis文件夹下。【目的:方便后续修改】

复制命令为【cp redis.conf /root/myredis】执行过程如下所示:

 1 [root@bogon bin]# mkdir /root/myredis
 2 [root@bogon bin]# cd ../../
 3 [root@bogon local]# cd src
 4 [root@bogon src]# ls
 5 redis
 6 [root@bogon src]# cd redis

10. 复制成功后,到/root/myredis进行查看,如下所示:

 Redis启动

切换到usr/local/redis/bin目录,通过命令【./redis-server /root/myredis/redis.conf】进行启动,启动成功后,如下所示:

redis默认的窗口是前台显示,不可以关闭的,需要重新打开一个窗口,通过redis客户端【/usr/local/redis/bin/redis-cli】进行访问。如下所示:

通过按Ctrl+C,可以关闭redis打开的服务端窗口,返回命令窗口,如下所示:

修改Redis为后台运行

redis默认为窗口运行,一旦关闭,则停止,可以通过修改配置文件/root/myredis/redis.conf,使redis后台运行,如下所示:

关于Linux下如何修改文件,可参考上一篇博文。

重新启动redis,则以守护进程运行,如下所示:

查看Redis进程

通过命令【ps -ef|grep redis】查看redis相关进程,如下所示:

 Redis关闭服务

通过命令【./redis-cli shutdown】关闭redis服务,如下所示:

 以上就是Redis的下载,安装,启动,关闭的整个流程。

编译异常处理

如果在编译redis的过程中,出现如下错误,则表示gcc版本太低,需要升级。错误如下所示:

如果以上错误,需要执行三个命令进行升级,如下所示:

yum -y install centos-release-scl

yum -y install devtoolset-9-gcc devtoolset-g-gcc-c++ devtoolset-9-binutils

scl enable devtoolset-9 bash

执行过程,如下所示:

冬夜读书示子聿(yù)

陆游 〔宋代〕

纸上得来终觉浅,绝知此事要躬行。
