Redis数据库的编译安装方法

一、Redis介绍

Redis 是完全开源免费的，遵守BSD协议，是一个高性能(NOSQL)的key-value数据库,Redis是一个开源的使用ANSI C语言编写、支持网络、可基于内存亦可持久化的日志型、Key-Value数据库，并提供多种语言的API。

Redis是一个非关系型数据库，与传统数据库不同的是redis的数据是存在内存中的，所以读写速度非常快，因此 redis 被广泛应用于缓存方向。另外，redis 也经常用来做分布式锁。 redis 提供了多种数据类型来支持不同的业务场景。 除此之外，redis 支持事务 、持久化、LUA脚本、LRU驱动事件、多种集群方案。

二、检查本地系统版本

1.检查系统版本

[root@node01 ~]# cat /etc/os-release 
NAME="CentOS Linux"
VERSION="7 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="7"
PRETTY_NAME="CentOS Linux 7 (Core)"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:centos:centos:7"
HOME_URL="https://www.centos.org/"
BUG_REPORT_URL="https://bugs.centos.org/"

CENTOS_MANTISBT_PROJECT="CentOS-7"
CENTOS_MANTISBT_PROJECT_VERSION="7"
REDHAT_SUPPORT_PRODUCT="centos"
REDHAT_SUPPORT_PRODUCT_VERSION="7"

2.检查系统内核版本

[root@node01 ~]# uname -r
3.10.0-957.el7.x86_64

三、下载Redis的源码包

1.下载redis源码包

[root@node01 redis]# wget https://download.redis.io/releases/redis-6.2.6.tar.gz
--2022-11-24 18:36:42--  https://download.redis.io/releases/redis-6.2.6.tar.gz

2022-11-24 18:36:43 (4.37 MB/s) - ‘redis-6.2.6.tar.gz’ saved [2476542/2476542]

2.解压源码包

[root@node01 redis]# tar -xzf redis-6.2.6.tar.gz
[root@node01 redis]# ls
redis-6.2.6  redis-6.2.6.tar.gz
[root@node01 redis]# 

四、关闭防火墙和selinux

1.关闭防火墙

systemctl stop firewalld.service
systemctl disable firewalld.service

2.关闭selinux

[root@node01 redis]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
[root@node01 redis]# setenforce 0
setenforce: SELinux is disabled
[root@node01 redis]# 

五、编译前环境准备工作

1.安装gcc模块

yum -y install gcc automake autoconf libtool make

2.进入deps/目录下编译

[root@node01 redis]# ls
redis-6.2.6  redis-6.2.6.tar.gz
[root@node01 redis]# cd redis-6.2.6/
[root@node01 redis-6.2.6]# ls
00-RELEASENOTES  CONDUCT       COPYING  INSTALL   MANIFESTO  redis.conf  runtest-cluster    runtest-sentinel  src    TLS.md
BUGS             CONTRIBUTING  deps     Makefile  README.md  runtest     runtest-moduleapi  sentinel.conf     tests  utils
[root@node01 redis-6.2.6]# cd deps/
[root@node01 deps]# ls
hdr_histogram  hiredis  jemalloc  linenoise  lua  Makefile  README.md  update-jemalloc.sh

make lua hiredis linenoise hdr_histogram jemalloc

六、编译安装Redis

[root@node01 redis-6.2.6]# make PREFIX=/usr/local/redis MALLOC=libc install
cd src && make install
make[1]: Entering directory `/data/redis/redis-6.2.6/src'
    CC Makefile.dep
make[1]: Leaving directory `/data/redis/redis-6.2.6/src'
make[1]: Entering directory `/data/redis/redis-6.2.6/src'

七、启动Redis

1.配置环境变量

[root@node01 redis-6.2.6]# cat /etc/profile.d/redis_init.sh 
export PATH=$PATH:/usr/local/redis/bin
[root@node01 redis-6.2.6]# source  /etc/profile.d/redis_init.sh

2.检查Redis版本

[root@node01 redis-6.2.6]# redis-server --version
Redis server v=6.2.6 sha=00000000:0 malloc=libc bits=64 build=a6a826a997b028c6

3.创建Redis相关目录

[root@node01 redis-6.2.6]# mkdir -p /usr/local/redis/{etc,logs,data}
[root@node01 redis-6.2.6]# 

4.编辑redis的配置文件

[root@node01 redis-6.2.6]# vim /usr/local/redis/etc/redis.conf
[root@node01 redis-6.2.6]# cat /usr/local/redis/etc/redis.conf
daemonize yes
supervised systemd
pidfile /var/run/redis.pid
port 6379
logfile /usr/local/redis/logs/redis.log
dbfilename dump.rdb
dir /usr/local/redis/data

maxmemory 1G

bind 192.168.3.172 127.0.0.1

timeout 300
loglevel notice

databases 16
save 900 1
save 300 10
save 60 10000

rdbcompression yes

maxclients 10000
appendonly yes
appendfilename appendonly.aof
appendfsync everysec
[root@node01 redis-6.2.6]# 

5.启动redis

[root@node01 redis-6.2.6]# redis-server /usr/local/redis/etc/redis.conf
[root@node01 redis-6.2.6]# 

八、连接Redis

1.检查redis端口

[root@node01 redis-6.2.6]# ps -ef |grep redis
root      8540     1  0 18:59 ?        00:00:00 redis-server 192.168.3.172:6379
root      8546  3927  0 19:00 pts/0    00:00:00 grep --color=auto redis

2.连接redis

[root@node01 redis-6.2.6]#  redis-cli  -h 192.168.3.172 -p 6379
