修改redis的配置文件
[root@centos8 conf]# vi redis.conf
配置項：
- #bind 127.0.0.1 /綁定訪問的ip,註釋 表示所有IP都可鏈接
- daemonize yes //使以daemon方式運行
- logfile “/home/work/redis/redis-6.0.3/logs/redis.log” //日誌保存目錄
- dir /home/work/redis/redis-6.0.3/data //數據保存目錄
- maxmemory 64MB //使用的最大內存數量
- io-threads 1 //#io線程數
生成供systemd使用的service文件
vi /lib/systemd/system/redis.service
[root@localhost redis-6.0.3]# vi /lib/systemd/system/redis.service

重新加載service文件
[root@localhost redis-6.0.3]# systemctl daemon-reload
啓動redis:
[root@localhost system]# systemctl start redis
[root@localhost system]# systemctl restart redis
[root@localhost system]# systemctl stop redis
測試從本地連接訪問:
[root@localhost bin]# systemctl start redis
[root@localhost bin]# ./redis-cli # 直接登錄本服務器默認6379端口
