Redis主从部署及sentinel配置详细教程

一、环境介绍

1.三个redis节点的IP规划

node-1 主redis 192.168.3.71
node-2 从redis 192.168.3.72
node-3 从redis 192.168.3.73

2.节点的系统版本

[root@node03 ~]# 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"

二、安装redis

1.下载Redis源码包

[root@node01 soft]# wget https://download.redis.io/releases/redis-6.2.6.tar.gz
--2022-06-01 18:23:58--  https://download.redis.io/releases/redis-6.2.6.tar.gz

2022-06-01 18:23:59 (5.31 MB/s) - ‘redis-6.2.6.tar.gz’ saved [2476542/2476542]

[root@node01 soft]# ll
total 2420
-rw-r--r-- 1 root root 2476542 Oct  4  2021 redis-6.2.6.tar.gz 

2.解压软件包

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

3.安装gcc相关模块

yum -y install gcc automake autoconf libtool make

4.编译软件目录deps/下内容

make lua hiredis linenoise hdr_histogram jemalloc

5.编译redis

make PREFIX=/usr/local/redis MALLOC=libc install

三、redis初始化环境配置

1.配置redis环境变量

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

2.检查redis的安装版本

[root@node01 redis-6.2.6]# redis-server --version
Redis server v=6.2.6 sha=00000000:0 malloc=libc bits=64 build=220bd54e8ce44ec8

3.创建redis相关目录

 mkdir -p /usr/local/redis/{
   etc,logs,data}

4.编辑redis配置文件

[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 192.168.3.71 127.0.0.1

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

四、启动redis

1.启动redis

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

2.检查redis状态

[root@node01 redis-6.2.6]#  ps -ef |grep redis
root      20551      1
