下载redis

在官网访问redis官网，下载你需要的版本 redis下载
这里我使用6.2.1版本

下载
wget https://download.redis.io/releases/redis-6.2.1.tar.gz
解压
tar xzf redis-6.2.1.tar.gz
进入目录
cd redis-6.2.1
编译
make

make可能遇到的错误，是因为gcc 版本低于 5.3 ，需要升级

查看当前gcc版本

升级gcc到9+

yum -y install centos-release-scl
yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
// 临时有效，退出 shell 或重启会恢复原 gcc 版本
scl enable devtoolset-9 bash
// 长期有效
echo "source /opt/rh/devtoolset-9/enable" >>/etc/profile

安装redis

redis 编译之后，文件存放在redis家目录的src文件夹中

创建目录
mkdir -p /opt/redis/{bin,conf,logs,data}
将src目录下的执行文件拷入bin目录中
cd src/
cp redis-benchmark redis-check-aof redis-check-rdb redis-cli redis-sentinel redis-server /opt/redis/bin/
将redis配置文件拷入conf文件夹
cp redis.conf  /opt/redis/conf/

设置开机启动

创建启动脚本

编辑redis启动文件
vim redis-start.sh

#!/bin/bash
/opt/module/redis-7000/src/redis-server /opt/module/redis-7000/redis.conf
赋予可执行权限
chmod +x redis-start.sh

创建关闭脚本

创建关闭脚本
vim redis-stop.sh
ps -aux|grep redis|awk '{print $2}'|xargs kill -15
赋予可执行权限
