內核目前版本
gnuhealth@localhost:~ $ uname -r
3.11.6
docker已經啟動
運行 docker info
gnuhealth@localhost:~ $ sudo docker info
[sudo] password for gnuhealth:
FATA[0000] Cannot connect to the Docker daemon. Is 'docker -d' running on this host?
運行 docker -d

iptables的版本也升級過，目前版本為
gnuhealth@localhost:~ $ iptables -V
iptables v1.4.21
運行iptables -t net -L
gnuhealth@localhost:~ $ sudo iptables -t net -L
iptables v1.4.21: can't initialize iptables table `net': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
如何解決這個nat表丟失的問題？？？？求大神指導···········
uj5u.com熱心網友回復：
這個升級內核導致模塊缺失可以重置docker的運行環境試試，如下：pkill docker
iptables -t nat -F
ifconfig docker0 down
brctl delbr docker0
docker -d

您好，非常感謝您的回復，但好像還是不行····輸入：iptables -t nat -F
lqt@localhost:~ $ sudo iptables -t nat -F
[sudo] password for gnuhealth:
iptables v1.4.21: can't initialize iptables table `nat': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
后面就是：
lqt@localhost:~ $ sudo ifconfig docker0 down
lqt@localhost:~ $ sudo brctl delbr docker0
lqt@localhost:~ $ sudo docker -d
INFO[0000] +job serveapi(unix:///var/run/docker.sock)
INFO[0000] Listening for HTTP on unix (/var/run/docker.sock)

腫么破？？

我也碰到了相同的問題，請問你這個問題解決掉了嗎？uj5u.com熱心網友回復：
內核版本只要是2.6.32-431.el6.x86_64或者以上的都沒問題，日志報你的內核版本過低可能是你的函式庫版本過低,嘗試更新下面的程式試試。yum upgrade device-mapper-libs -y
uj5u.com熱心網友回復：
樓主解決了沒，問題與你描述的一樣一樣的。。uj5u.com熱心網友回復：
謝謝，按照這個方式解決了問題uj5u.com熱心網友回復：
