docker启动时报错Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.
这里报错主要是因为docker启动时需要默认开启selinux,但是可能由于安装某些应用,我们关闭了selinux,所以此时我们需要设置/etc/sysconfig/docker
将下图标黄位置改为false,即设置docker启动时默认不需要开启selinux
# /etc/sysconfig/docker # Modify these options if you want to change the way the docker daemon runs OPTIONS='--selinux-enabled=false --log-driver=journald --signature-verification=false' if [ -z "${DOCKER_CERT_PATH}" ]; then DOCKER_CERT_PATH=/etc/docker fi # Do not add registries in this file anymore.
