nohup命令无法使用，也无法查询
[root@wy-node106 tmp]# nohup
bash: nohup: 未找到命令...
[root@wy-node106 tmp]# which nohup
/usr/bin/which: no nohup in (/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/data/program/java/bin:
/data/program/java/jre/bin:/root/bin)
但是查询安装包又能查到
[root@wy-node106 yum.repos.d]# rpm -qa|grep coreutils
policycoreutils-python-2.5-34.el7.x86_64
