docker网段不通问题

安装bridge-utils

yum install -y bridge-utils
或者
sudo rpm -ivh /home/zyyt/soft/docker_ins/bridge-utils-1.5-9.el7.x86_64.rpm

方法1（可能不成功）

sudo systemctl stop docker
sudo ip link set dev docker0 down
sudo brctl delbr docker0
sudo brctl addbr docker0
sudo ip addr add 172.17.xxx.1/24 dev docker0     (XXX:主机ip最后一段)
sudo ip link set dev docker0 up
sudo systemctl start docker
 ip addr

方法2

sudo chmod o+w /etc/systemd/system/docker.service
 vi /etc/systemd/system/docker.service 
  找到 ExecStart=/usr/bin/dockerd  XXX:主机ip最后一段
ExecStart=/usr/bin/dockerd --bip 172.17.XXX.1/24
  sudo systemctl daemon-reload
  sudo systemctl stop docker
  sudo systemctl start docker
 ip addr

docker24版本在

vi /usr/lib/systemd/system/docker.service
