Centos7 redis7.2 无法启动

使用yum install 安装了 redis
新增了一个配置文件和服务启动项
redis-server /etc/redis.clu/7001/redis.conf 命令行直接输入可以正常启动

bind 0.0.0.0
daemonize no
port 7001
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes
masterauth 123456
pidfile redis.pid
requirepass 123456

但是使用systemctrl无法正常启动
