配置用户组

[root@host-10-10-18-195 yang]# vim frr.sh
groupadd -g 92 frr
groupadd -r -g 85 frrvty
useradd -u 92 -g 92 -M -r -G frrvty -s /sbin/nologin 
  -c "FRR FRRouting suite" -d /var/run/frr frr

[root@host-10-10-18-195 yang]# bash frr.sh
groupadd: group 'frr' already exists
groupadd: GID '85' already exists
useradd: group 'frrvty' does not exist
