将下载的包存储在新创建的/opt/soft目录下
[root@nues ~]# mkdir /opt/soft   #创建soft文件夹
[root@nues ~]# cd /opt/soft
[root@nues soft]#  wget http://download.redis.io/releases/redis-5.0.6.tar.gz

2、安装组件

1

[root@nues soft]# yum groupinstall 'Development Tools'
[root@nues soft]# tar -xf redis-5.0.6.tar.gz -C /usr/local/  #解压到 /usr/local/路径

3、编译安装

[root@nues soft]# yum -y install gcc make  #安装组件
[root@nues soft]# cd /usr/local/
[root@nues local]# mv redis-5.0.6 redis  #修改名字
[root@nues local]# cd redis
[root@nues redis]# make   #编译

编译redis.webp

1
[root@nues redis]# make install PREFIX=/usr/local/redis  # 参数：后面跟 PREFIX=/usr/local/redis  指定redis的安装路径

拷贝执行文件到/usr/local/bin下
[root@nues redis]# cd /usr/local/redis/bin
[root@nues bin]# cp * /usr/local/bin/

[root@localhost redis]# mkdir -p /data/redis/logs #创建数据目录和日志存储目录
[root@nues ~]# vim /usr/local/redis/redis.conf
修改以下行
#行号#
69 #bind 127.0.0.1 # 添加#号 注释掉，以便外网访问
88 protected-mode no  #yes改成no 关闭保护模式
136 daemonize yes #no 改成ye 开启守护进程模式
171 logfile "/data/redis/logs/redis.log"  #指定redis log 日志存储路径以及日志文件名称
263 dir /data/redis   #指定AOF和RDB存储路径
507 requirepass nues1234   #去掉注释， 后面设置redis的密码

5、创建用户

#赋权(注意要跟systemd中指定的用户一样)
[root@nues ~]# groupadd appadmin
[root@nues ~]# useradd -g appadmin -s /sbin/nologin appadmin
[root@nues ~]# chown -R appadmin. /usr/local/redis
[root@nues ~]# chown -R appadmin. /data/redis/

[root@nues ~]#  vim /usr/local/redis/redis.conf
#行号#
507 requirepass nues1234       # requirepass 后面的为修改后的密码
[root@nues ~]# systemctl restart redis #重启服务 修改密码生效
验证密码
[root@nues ~]# redis-cli
127.0.0.1:6379> auth nues1234
OK
127.0.0.1:6379> ping
PONG
远程访问，注意选项后面必须有个空格，然后再写密码和IP
[root@nues ~]# redis-cli  -p 6379 -c -h 10.15.3.233
10.15.3.233:6379> auth nues1234
