$ yum install docker
$ docker --version
Docker version 1.12.6, build 88a4867/1.12.6

当我启动docker时:

$ service docker start

    Redirecting to /bin/systemctl start  docker.service
    Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

无法设置cookie dm\u task\u set\u cookie失败 ?

修复了I did echo“y”| sudo dmsetup udevcomplete|u all 它能够启动

many others 遇到此问题(或跳到下面的解决方案):

这里的一般问题是早期版本的Docker可能 devicemapper 将信号量/cookie泄漏到容器的装载空间之外。对我来说,这是在多次快速给docker打电话之后发生的 build , run , rm stop 等

这可能会导致系统的信号量数组在未清除的情况下填满,这将阻止所有docker命令工作(并可能影响依赖于这些共享信号量的其他系统功能)。

你可以通过 increasing the number of semaphore arrays ,或者像下面这样清除一些旧数组。

公认答案使用 clearing all semaphores dmsetup udevcomplete_all ,但如果有其他容器或进程依赖于这些cookie/信号量,则可能不希望这样做。

semaphore arrays --这些在我的机器上已满(128个阵列):

$ ipcs -u

------ Semaphore Status --------
used arrays = 128
allocated semaphores = 1136

------ Messages Status --------
allocated queues = 0
used headers = 0
used space = 0 bytes

------ Shared Memory Status --------
segments allocated 2
pages allocated 20057
pages resident  16214
pages swapped   2
Swap performance: 0 attempts     0 successes

这些信号量对应于dm cookies,如所示 ipcs 和 dmsetup udevcookies (仅显示最近的Cookie;查找匹配项) semid

$ ipcs -s -t
semid    owner      last-op                    last-changed              
540278908 root        Sat Jun 13 10:03:57 2020   Sat Jun 13 10:03:57 2020  
548634749 root        Sat Jun 13 10:09:22 2020   Sat Jun 13 10:09:22 2020  
555876478 root        Sat Jun 13 10:14:05 2020   Sat Jun 13 10:14:05 2020  
572096639 root        Sat Jun 13 11:43:42 2020   Sat Jun 13 11:43:42 2020 
...

$ dmsetup udevcookies
Cookie       Semid      Value      Last semop time           Last change time
0xd4d819c    540278908  1          Sat Jun 13 10:03:57 2020  Sat Jun 13 10:03:57 2020

...

为了避免影响旧的信号量/cookie,我想使用 msetup udevreleasecookie <cookie ID> :

# filter the list of cookies, get the IDs, and feed it to udevreleasecookie:

$ REGEX_STR="Jun 13"    # change to whatever filter you need
$ dmsetup udevcookies | grep -E "$REGEX_STR" | awk '{ print $1 }' | xargs -n1 dmsetup udevreleasecookie

# check that the semaphores are gone
$ ipcs -s -t | grep -E "root" | grep -E "$REGEX_STR"    
...
$

这让我可以跑步 docker
