1.产生原因:
Docker报错 WARNING: IPv4 forwarding is disabled. Networking will not work.
1.# docker run -it -p 30001:22 --name=centos-ssh centos /bin/bash
2.WARNING: IPv4 forwarding is disabled. Networking will not work.
修改这个错误
1.# vim /usr/lib/sysctl.d/00-system.conf
2.添加这个文档
net.ipv4.ip_forward=1
3.重启
# systemctl restart network
完成以后，删除错误的容器，再次创建新容器，就不再报错了,数据库连接windows系统的Nacivat也不会报错了
