一台Centos7 机器 最好可以上网，安装wget（上网下载工具）
yum install wget2.下载包
直接用wget 下载 如果没有联网 也可以下载好传到机器上；
Redis下载地址是 https://download.redis.io/releases/redis-6.2.6.tar.gz
3.解压[root@localhost soft]# ls redis-6.2.6.tar.gz [root@localhost soft]# tar -xvf redis-6.2.6.tar.gz4.编译
阅读README.md 大致查看编译步骤；
[root@localhost redis-6.2.6]# make
cd src && make all
CC adlist.o
/bin/sh: cc: 未找到命令
make[1]: *** [adlist.o] 错误 127
make[1]: 离开目录“/soft/redis-6.2.6/src”
报错，没有c 编译环境 安装 GCC
yum install gcc
安装后最好在清除一下 之前安转失败的文件
make distclean
继续安装
make
构建成功后 src 下回生成执行脚本
5.执行7021:C 12 Mar 2022 14:45:45.350 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

成功执行
6.开启自启动上面的执行方式不是很友好，要想把软件按照到服务里面去，看README.md 可以了解如何去做
[root@localhost redis-6.2.6]# make install PREFIX=/soft/installdir //会把对应的命令迁移到这个目录 [root@localhost bin]# pwd /soft/installdir/bin [root@localhost bin]# ls redis-benchmark redis-check-aof redis-check-rdb redis-cli redis-sentinel redis-server [root@localhost bin]# //加载到PATH 在文件后面添加 export REDIS_HOME=/soft/installdir/redis6 export PATH=$REDIS_HOME/bin:$PATH
设置开机自启动，redis_init_script 位于位于Redis的 /utils/ 目录下，配置号一些启动的脚本位置在该文件内；
//复制该脚本到启动 cp redis_init_script /etc/init.d/redisd //复制自动启动的配置文件 mkdir /etc/redis cp redis.conf /etc/redis/6379.conf //开启开机自启动 chkconfig redisd on7.安装多个实例
就是在一台服务器上部署多个redis 实例
[root@localhost utils]# ./install_server.sh Welcome to the redis service installer This script will help you easily set up a running redis server This systems seems to use systemd. Please take a look at the provided example service unit files in this directory, and adapt and install them. Sorry!
如果出现上述错误,注释install_server.sh 中这段代码
#bail if this system is managed by systemd
#_pid_1_exe="$(readlink -f /proc/1/exe)"
#if [ "${_pid_1_exe##*/}" = systemd ]
#then
# echo "This systems seems to use systemd."
# echo "Please take a look at the provided example service unit files in this directory, and adapt and install them. Sorry!"
# exit 1
#fi
处理错误后继续执行
