systemctl start dockerJob for docker.service failed because the control process exited with error

1、docker安装完启动失败

[root@tbase1 ~]# systemctl start docker Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details. [root@tbase1 ~]# [root@tbase1 ~]# journalctl -xe Oct 22 11:10:36 tbase1 systemd[1]: Unit docker.service entered failed state. Oct 22 11:10:36 tbase1 systemd[1]: docker.service failed. Oct 22 11:10:38 tbase1 systemd[1]: docker.service holdoff time over, scheduling restart.

[root@tbase1 ~]# systemctl stop docker [root@tbase1 ~]# [root@tbase1 ~]# [root@tbase1 ~]# systemctl start docker Job for docker.service failed because start of the service was attempted too often. See "systemctl status docker.service" and "journalctl -xe" for details. To force a start use "systemctl reset-failed docker.service" followed by "systemctl start docker.service" again. [root@tbase1 ~]# [root@tbase1 ~]#

2、查看网上其他网友的解决办法是把/etc/docker/daemon.json 修改为/etc/docker/daemon.conf,其实就是不启用daemon.json。但是我的是新安装的docker，/etc/docker下面没有这个文件。

[root@tbase1 docker]# cd /etc/docker/ [root@tbase1 docker]# ls key.json [root@tbase1 docker]#

3、直接有dockerd启动，查看日志

[root@tbase1 docker]# dockerd INFO[2020-10-22T11:17:08.729949738+08:00] Starting up INFO[2020-10-22T11:17:08.732247548+08:00] parsed scheme: "unix" module=grpc INFO[2020-10-22T11:17:08.732274835+08:00] scheme "unix" not registered, fallback to default scheme module=grpc INFO[2020-10-22T11:17:08.732298172+08:00] ccResolverWrapper: sending update to cc: {[{unix:///run/containerd/containerd.sock 0 <nil>}] <nil>} module=grpc INFO[2020-10-22T11:17:08.732306615+08:00] ClientConn switching balancer to "pick_first" module=grpc INFO[2020-10-22T11:17:08.733766403+08:00] parsed scheme: "unix" module=grpc INFO[2020-10-22T11:17:08.733793158+08:00] scheme "unix" not registered, fallback to default scheme module=grpc INFO[2020-10-22T11:17:08.733807436+08:00] ccResolverWrapper: sending update to cc: {[{unix:///run/containerd/containerd.sock 0 <nil>}] <nil>} module=grpc INFO[2020-10-22T11:17:08.733813642+08:00] ClientConn switching balancer to "pick_first" module=grpc failed to start daemon: error initializing graphdriver: /var/lib/docker contains several valid graphdrivers: overlay2, devicemapper; Please cleanup or explicitly choose storage driver (-s <DRIVER>) [root@tbase1 docker]#

错误主要在于failed to start daemon: error initializing graphdriver: /var/lib/docker contains several valid graphdrivers: overlay2, devicemapper; Please cleanup or explicitly choose storage driver (-s <DRIVER>)。

4、按照上面的报错，先把/var/lib/docker下面的overlay2,devicemapper mv掉

[root@tbase1 docker]# cd /var/lib/ [root@tbase1 lib]# ls AccountsService color dnsmasq geoclue misc pacemaker pulse spamassassin upower alsa colord docker gssproxy mlocate PackageKit rasdaemon stateless virtuoso alternatives containerd dovecot hyperv net-snmp pcp rhsm stolon vmware amanda containers etcd initramfs NetworkManager pcsd rpcbind systemd xkb authconfig corosync flatpak iscsi nfs Pegasus rpm tpm yum bluetooth cs fprint libvirt openlmi-registration plymouth rpm-state tuned chrony dbus games logrotate openlmi-storage polkit-1 rsyslog udisks2 cockpit dhclient gdm machines os-prober postfix samba unbound [root@tbase1 lib]# cd docker/ [root@tbase1 docker]# ls containers devicemapper image network overlay2 plugins runtimes swarm tmp trust volumes [root@tbase1 docker]# [root@tbase1 docker]# [root@tbase1 docker]# mv overlay2 overlay2_back [root@tbase1 docker]# mv devicemapper/ devicemapper_bak [root@tbase1 docker]# ls -ltr total 0 drwx------ 4 root root 32 Aug 23 20:02 plugins drwx------ 2 root root 6 Aug 23 20:02 trust drwxr-x--- 3 root root 19 Aug 23 20:02 network drwx------ 2 root root 6 Aug 23 20:02 swarm drwx------ 4 root root 42 Aug 23 20:09 image drwx------ 5 root root 53 Aug 23 20:10 devicemapper_bak drwx------ 3 root root 78 Aug 23 20:10 containers drwx------ 3 root root 97 Aug 23 20:10 volumes drwx------ 2 root root 6 Oct 22 11:17 tmp drwx------ 2 root root 6 Oct 22 11:17 runtimes drwx------ 3 root root 40 Oct 22 11:17 overlay2_back

5、再次启动docker
