Centos7无法启动docker问题

异常信息：

Error starting daemon: Error initializing network controller: list bridge addresses failed: no available network

 

 

现象：

[root@localhost ~]# systemctl start docker

Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

 

 

 

解决：

安装   yum install bridge-utils

运行：

sudo brctl addbr docker0
sudo ip addr add 192.168.42.1/24 dev docker0
sudo ip link set dev docker0 up
ip addr show docker0
sudo systemctl restart docker
sudo iptables -t nat -L -n    

重启：

 systemctl start docker
