IPv4 forwarding is disabled. Networking will not work.
centos 7 docker 启动了一个web服务 但是启动时 报
WARNING: IPv4 forwarding is disabled. Networking will not work.
网上查询了下 需要做如下配置
解决办法:
# vi /etc/sysctl.conf
或者
# vi /usr/lib/sysctl.d/00-system.conf
添加如下代码:
net.ipv4.ip_forward=1
重启network服务
# systemctl restart network
查看是否修改成功
# sysctl net.ipv4.ip_forward
如果返回为“net.ipv4.ip_forward = 1”则表示成功了
