我无法用iptables错误启动docker服务

Question

这是我的linux版本信息CentOS Linux release 7.0.1406 (Core)， 我的iptables版本是v1.4.21

使用命令yum install docker安装docker之后， 我正在尝试使用命令service docker start启动docker，但我无法启动docker。

收到的错误消息是

这是lsmod | grep -E 'iptable|nat|conntrack'

的输出

Answer 1

＃make menuconfig

- ＆GT;网络支持

- ＆GT;网络选项

- ＆GT;网络包过滤框架

打开那些NAT，NF_NAT相关选项

重新编译，重新启动新内核

＃make all

#make modules_install

＃make install

之后，＃lsmod | grep nat，如果这些模块显示，它应该工作。

Answer 2

我已经解决了这个问题。我用＆＃39; nat＆＃39;重新编译了内核。相关选项打开，因为在重新编译之前已在内核中删除了该选项。
