Docker 1.3无法在RHEL6.5上启动

Question

我之前访问过https://docs.docker.com/installation/rhel/,在rhel6.5上安装docker.这曾经工作到今天,直到我决定运行"yum update"并升级到docker1.3.

现在,/ etc/init.d/docker启动失败.

-bash-4.1$ sudo /etc/init.d/docker status
           docker dead but pid file exists

/ var/log/docker的内容:

-bash-4.1$ more /var/log/docker

我还没有选择升级到rhel7,并且已经尝试过了

• yum downgrade - 但yum list不再列出旧版本
• 编译旧的docker源代码,但是如果没有安装docker二进制文件,docker就不会让你构建二进制文件:(

Answer 1

/ usr/bin/docker:重定位错误:/ usr/bin/docker:符号dm_task_get_info_with_deferred_remove,版本Base未在文件libdevmapper.so.1.02中定义,带有链接时间参考

我本周在工作中遇到了这个问题(也在RHEL6.5上).我相信你拥有的lib-device-mapper不会导出Docker需要的符号("Base").我通过将lib-device-mapper升级到版本1.02.90来解决这个问题.

您可能必须启用public_ol6_latestrepo才能获得此包.

sudo yum-config-manager --enable public_ol6_latest

然后安装包:

sudo yum install device-mapper-event-libs

Answer 2

TL; DR:在我的情况下,我需要device-mapper-libs在CentOS/RHEL 6.5上升级软件包.详情如下.

$ yum update -y device-mapper-libs

在RHEL/CentOS 6.5上,我在尝试运行docker守护程序时遇到了同样的错误:

$ docker -d
INFO[0000] +job serveapi(unix:///var/run/docker.sock)
INFO[0000] WARNING: You are running linux kernel version 2.6.32-431.el6.x86_64, which might be unstable running docker. Please upgrade your kernel to 3.8.0.
INFO[0000] Listening for HTTP on unix (/var/run/docker.sock)
docker: relocation error: docker: symbol dm_task_get_info_with_deferred_remove, version Base not defined in file libdevmapper.so.1.02 with link time reference

在进行故障排除时,我遇到了讨论docker.io:在 Debian 升级后,docker无法运行.

这里参考的是"修复"之前的环境:

$ uname -a
Linux build1 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 22 03:15:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

$ cat /etc/redhat-release
CentOS release 6.5 (Final)

升级之前device-mapper-libs是版本1.02.79.在上面链接的Debian错误报告中,有人指出Docker 1.4.1(与原版海报询问的版本不同)是针对较新版本编译的device-mapper-libs(libdevmapper 2:1.02.90-1注意Debian中的包名称不同) .

$ yum info device-mapper-libs
Installed Packages
Name        : device-mapper-libs
Arch        : x86_64
Version     : 1.02.79
Release     : 8.el6
<...snip...>

更新device-mapper-libs修复了问题:

$ yum update -y device-mapper-libs

# Yep, the package was updated to the latest version (1.02.90)
$ rpm -qi device-mapper-libs
Name        : device-mapper-libs           Relocations: (not relocatable)
Version     : 1.02.90                           Vendor: CentOS
Release     : 2.el6_6.1                     Build Date: Wed 26 Nov 2014 
<...snip...>

更新完成后,docker守护程序将成功启动:

$ # docker -d
INFO[0000] +job serveapi(unix:///var/run/docker.sock)
INFO[0000] WARNING: You are running linux kernel version 2.6.32-431.el6.x86_64, which might be unstable running docker. Please upgrade your kernel to 3.8.0.

希望这可以帮助!
