centos docker-ce 安装 启动报错如何定位

CentOS 7 (使用yum进行安装)

# step 1: 安装必要的一些系统工具
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
# Step 2: 添加软件源信息
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
# Step 3: 更新并安装 Docker-CE
sudo yum makecache fast
sudo yum -y install docker-ce
# Step 4: 开启Docker服务
sudo service docker start

# 注意：
# 官方软件源默认启用了最新的软件，您可以通过编辑软件源的方式获取各个版本的软件包。例如官方并没有将测试版本的软件源置为可用，你可以通过以下方式开启。同理可以开启各种测试版本等。
# vim /etc/yum.repos.d/docker-ce.repo
#   将 [docker-ce-test] 下方的 enabled=0 修改为 enabled=1
#
# 安装指定版本的Docker-CE:
# Step 1: 查找Docker-CE的版本:
# yum list docker-ce.x86_64 --showduplicates | sort -r
#   Loading mirror speeds from cached hostfile
#   Loaded plugins: branch, fastestmirror, langpacks
#   docker-ce.x86_64            17.03.1.ce-1.el7.centos            docker-ce-stable
#   docker-ce.x86_64            17.03.1.ce-1.el7.centos            @docker-ce-stable
#   docker-ce.x86_64            17.03.0.ce-1.el7.centos            docker-ce-stable
#   Available Packages
# Step2 : 安装指定版本的Docker-CE: (VERSION 例如上面的 17.03.0.ce.1-1.el7.centos)
# sudo yum -y install docker-ce-[VERSION]

docker 官方安装文档  https://docs.docker.com/install/linux/docker-ce/centos/#set-up-the-repository

 

安装完毕后

# service docker start

错误：

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.

# service docker status

信息如下

● docker.service - Docker Application Container Engine

   Loaded: loaded (/usr/lib/systemd/system/docker.service; disabled; vendor preset: disabled)

   Active: failed (Result: start-limit) since Tue 2018-11-13 11:14:20 CST; 8s ago

     Docs: https://docs.docker.com

  Process: 1381 ExecStart=/usr/bin/dockerd (code=exited, status=1/FAILURE)

 Main PID: 1381 (code=exited, status=1/FAILURE)

 

出现这样的问题，如何进行具体错误定位；

1、首先根据提示进行操作，例如systemctl status docker.service" and "journalctl -xe"

systemctl status docker.service

● docker.service - Docker Application Container Engine

   Loaded: loaded (/usr/lib/systemd/system/docker.service; disabled; vendor preset: disabled)

但是看到的信息还是不知道具体错误，还是没有找到具体错误；

 

2、Docker 日志都在哪里？

CentOS 7/RHEL 7/Fedora journalctl -u docker.service

CoreOS journalctl -u docker.service

#journalctl -u docker.service

重点在红字加粗部分

再琢磨 异常日志，注意到 mkfs，遂手动执行了下：

mkfs.xfs -m crc=0,finobt=0 /dev/mapper/docker-253:1-34265854-base

报：
=================================

[root@Docker ~]# mkfs.xfs -m crc=0,finobt=0 /dev/mapper/docker-253:1-34265854-base

unknown option -m finobt=0
Usage: mkfs.xfs

--------------------------------

man mkfs.xfs 了下，的确没有 -m 参数

但...查了下网络资料，发现别人的 man mkfs.xfs 资料有-m参数

问题原因：

===========================================
很明显了：mkfs.xfs版本太低，遂更新：
yum update xfsprogs
重启docker服务，正常！

===================================

 

希望对大家有所帮助
