Redis集群安装部署和基础配置

2024-11-19 分类：日常运维 阅读(0) 评论(0)

概述

redis官网：https://redis.io/

安装环境

| 部署ip | 安装软件 | 开放端口 | |:--------------:|:-----------:|:---------------------:| | 192.168.199.10 | redis-6.0.9 | 6379/16379/6380/16380 | | 192.168.199.11 | redis-6.0.9 | 6379/16379/6380/16380 | | 192.168.199.12 | redis-6.0.9 | 6379/16379/6380/16380 |

安装部署

依赖环境安装
yum -y install gcc gcc-c++ kernel-devel make cpp binutils glibc glibc-kernheaders glibc-common glibc-devel tcl wget
yum -y install centos-release-scl && yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils && scl enable devtoolset-9 bash
echo "source /opt/rh/devtoolset-9/enable" >> /etc/profile
source /etc/profile
redis安装
tar zxf redis-6.0.9.tar.gz && cd redis-6.0.9
make && make PREFIX=/data/redis install
<!--根据实际情况更改路径-->
mkdir -p /data/redis/etc
cp redis.conf /data/redis/etc/
cp -ra /data/redis/ /data/redis01
基础配置
vim /data/redis/etc/redis.conf

修改一下配置
======



redis以守护进程的方式运行
===============



no表示不以守护进程的方式运行(会占用一个终端)
========================



daemonize yes


客户端闲置多长时间后断开连接，默认为0关闭此功能
========================



timeout 300


设置redis日志级别，默认级别：notice
=======================



loglevel verbose


设置日志文件的输出方式,如果以守护进程的方式运行redis 默认:""
===================================



并且日志输出设置为stdout,那么日志信息就输出到/dev/null里面去了
=======================================



logfile stdout


设置密码授权
======



requirepass \<设置密码\>
====================



监听ip
====



bind 0.0.0.0


监听端口
====



port 6379


开启集群功能
======



cluster-enabled yes


vim /data/redis01/etc/redis.conf

`cluster-enabled yes`

防火墙开放端口

三台机器都放行端口

firewall-cmd --zone=public --add-port=6379/tcp --permanent
firewall-cmd --zone=public --add-port=16379/tcp --permanent
firewall-cmd --zone=public --add-port=6380/tcp --permanent
firewall-cmd --zone=public --add-port=16380/tcp --permanent
firewall-cmd --reload
setenforce 0
配置启停脚本
vim /data/start_redis.sh

#!/bin/bash
cd /data/redis/
./bin/redis-server  ./etc/redis.conf
cd /data/redis01/
./bin/redis-server  ./etc/redis.conf


vim /data/stop_redis.sh

`#!/bin/bash
ps -aux | grep redis | awk -F " " '{print $2}' | xargs kill -9`
