起因是使用 docker 运行 jenkins，始终启动不起来，运行命令：

docker run --name jenkins -p 8180:8080 jenkins/jenkins

之后更换了几个 jenkins 镜像，发现似乎并不是 jenkins 镜像的问题。于是尝试运行 mysql 镜像：

docker run -p 3307:3306 -e MYSQL_RANDOM_ROOT_PASSWORD=123456 --name mysql mysql

也是一样因为没有权限无法创建 socket 而退出，目前尝试过的方式是容器内外的用户均切换到 root 用户运行，以及对/var/run/docker.sock文件进行权限修改、删除重新生成等，Google 未找到一样的情况，大多是单独运行 mysql 或者单独运行 jenkins 时出现这种错误的处理，单独运行 jenkins 我是没问题的，无奈只能来求助了。

第 1 条附言 · 2020-04-15 17:38:59 +08:00

问题已经得到了解决，是 apparmor 引发的问题，我的系统是 deepin 15.11，自带 apparmor ，先说找到的解决方式：

直接卸载 apparmor （太过粗暴）
安装 2.12-4 版本的apparmor （对我无效）
docker运行时通过命令选项禁用 apparmor

升级 2.12-4 的方式：添加 deb http://br.archive.ubuntu.com/ubuntu bionic main到 /etc/apt/sources.list 中，然后执行：

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 3B4FE6ACC0B21F32
sudo apt update
sudo apt install apparmor=2.12-4ubuntu5

升级 apparmor 版本的方式对我也没效果，所以最后我使用的是在 docker run 的时候用 --security-opt apparmor=unconfined 选项指定禁用 apparmor ：

docker run --security-opt apparmor=unconfined -p 3307:3306 -e MYSQL_RANDOM_ROOT_PASSWORD=123456 --name mysql mysql

将容器外部的 socket 描述符映射到容器内试试

@wellsc #1 通过 `-v /var/run/docker.sock:/var/run/docker.sock` 命令进行映射也是一样的结果，没效果

试着用 user=root 来创建容器

而且，这个 Jenkins 没有映射本地持久化目录保存吗？ Jenkins 的 dockerfile 里面写了有一个默认用户是 jenkins，你-v 挂载本地目录，然后 chown 试试看

2020-04-14 23:56:44 +08:00 via Android

@CRUD 这个映射的是 docker cli 和 daemon 之间的 socket，不是 docker 应用用的那个 socket

CRUD

2020-04-15 09:53:12 +08:00

@DCCooper #4 有试过用 `-u root`或是`-u 0`来指定使用 root 用户运行，不过也是不行，挂载`jenkins_home`目录也有试过，感觉不是这个问题为了尽可能精简命令上面就没列出来了。

至于你上面说的-v 挂载本地目录，然后 chown，我试了一下，步骤是创建容器：
`docker run --rm --name jenkins -u root -p 8100:8080 -p 50000:50000 -v /home/jenkins:/var/jenkins_home jenkins/jenkins`
然后 chown /home/jenkins 目录给 root 或是 jenkins，都不行

CRUD

2020-04-15 09:55:56 +08:00

@Trim21 #5 好吧，我只知道只有这个 socket 描述符了，docker 应用的 socket 该如何映射呢？
总觉得跟容器内环境可能没太大关系，问题更像是 docker 应用出了问题，不过没什么 docker 的经验，找不出来在哪..

把 selinux 关了试试？
