LINUX随笔九 nohup失效和镜像源

Posted 2022-04-13 哭泣的馒头

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 
policycoreutils-2.5-34.el7.x86_64 
coreutils-8.22-21.el7.x86_64 
#########################直接卸载重新安装 
[root@wy-node106 yum.repos.d]# rpm -e --nodeps coreutils-8.22-21.el7.x86_64 
#########################配置本地yum源 
[root@wy-node106 yum.repos.d]# cat local.repo 
[local] 
name=local 
baseurl=file:///mnt/iso/ 
enabled=1 
gpgcheck=0 
[root@wy-node106 yum.repos.d]# 
[root@wy-node106 yum.repos.d]# ls /data/CentOS-7-x86_64-DVD-1804-7.5.iso 
/data/CentOS-7-x86_64-DVD-1804-7.5.iso 
[root@wy-node106 yum.repos.d]# mount -o loop /data/CentOS-7-x86_64-DVD-1804-7.5.iso /mnt/iso 
##########重新安装 
yum install coreutils -y 
###########检查是否已有 
[root@wy-node106 yum.repos.d]# which nohup
