• 查看harbor服务是正常的

[root@k8s-server-4 harbor]# docker-compose ps
      Name                     Command                  State                 Ports

registryctl         /home/harbor/start.sh            Up (healthy)

• 于是查看端口监听,也是正常的

[root@k8s-server-4 harbor]# lsof -i:1080
COMMAND     PID USER   FD   TYPE    DEVICE SIZE/OFF NODE NAME
docker-pr 16465 root    4u  IPv6 276635930      0t0  TCP *:socks (LISTEN)

• 于是开一下防火墙,关了

[root@k8s-server-4 harbor]# firewall-cmd --list-ports
FirewallD is not running

• 于是查看ip是否开启转发

[root@k8s-server-4 harbor]# sysctl net.ipv4.ip_forward
net.ipv4.ip_forward = 0

• 没有转发，打开就行

[root@k8s-server-4 harbor]# vim /etc/sysctl.conf
net.ipv4.ip_forward = 1 # 这个配置改成1，0是没打开
# 执行命令 service network restart
[root@k8s-server-4 harbor]# service network restart

• 重启network，服务正常
