我无法使用 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

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

收到的错误信息是

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

的输出

Answer 1

我已经解决了问题。我已经重新编译了带有 'nat' 相关选项的内核，因为在重新编译之前该选项已在内核中删除。

Answer 2

# 制作菜单配置

--> 网络支持

--> 网络选项

--> 网络包过滤框架

打开那些NAT，NF_NAT相关选项

重新编译，重启新内核

#使全部

#使modules_install

# 安装

之后，#lsmod | grep nat ，如果这些模块显示，它应该可以工作。
