Linux – Clickhouse: Failed to get D-Bus connection: Operation not permitted – CentOS 7, no docker image

centos7linuxservicesystemctl

I am trying to set up a Clickhouse server on my WSL which is based on CentOS. After following instructions in this page, and installing the DB successfully, when I want to enable the service I get following:

# systemctl enable clickhouse-server
clickhouse-server.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig clickhouse-server on

And when I want to start the service, I get the below error:

# systemctl start clickhouse-server
Failed to get D-Bus connection: Operation not permitted

I googled but all I got were issues about CentOS docker images which did not work for me.
Is there any way to make it work?

I've been googling the exact same thing.

apachectl start in Centos7 seems to work for me. Same with mariadb.

Not sure how helpful that is. I've run httpd directly. Maybe you could do the same with clickhouse?

My guess is that you're running a non-privileged container. systemd requires CAP_SYS_ADMIN capability but Docker drops that capability in the non privileged containers, in order to add more security.

systemd also requires RO access to the cgroup file system within a container. You can add it with –v /sys/fs/cgroup:/sys/fs/cgroup:ro

So, here a few steps on how to run CentOS with systemd inside a Docker container:

Pull centos image
Set up a docker file like the one below:

FROM centos
MAINTAINER "Yourname" <youremail@address.com>
ENV container docker
RUN yum -y update; yum clean all
RUN yum -y install systemd; yum clean all; \
(cd /lib/systemd/system/sysinit.target.wants/; for i in *; do [ $i == systemd-tmpfiles-setup.service ] || rm -f $i; done); \
rm -f /lib/systemd/system/multi-user.target.wants/*;\
rm -f /etc/systemd/system/*.wants/*;\
rm -f /lib/systemd/system/local-fs.target.wants/*; \
rm -f /lib/systemd/system/sockets.target.wants/*udev*; \
rm -f /lib/systemd/system/sockets.target.wants/*initctl*; \
rm -f /lib/systemd/system/basic.target.wants/*;\
rm -f /lib/systemd/system/anaconda.target.wants/*;
VOLUME [ "/sys/fs/cgroup" ]
CMD ["/usr/sbin/init"]

Build it - docker build -t centos7-systemd - < mydockerfile
Run a container with docker run --rm --privileged -ti -e container=docker -v /sys/fs/cgroup:/sys/fs/cgroup centos7-systemd /usr/sbin/init
You should have systemd in your container

Linux – Can’t start isc-dhcp-server because of the Error : Not configured to listen on any interfaces

dhcpd needs 2 files to work:
/etc/default/dhcpd.conf -- defines the interfaces(what you are missing)
and
/etc/dhcp/dhcpd.conf -- the file you have already finished up

the contents of /etc/default/dhcpd.conf should look something like this:

# /etc/default/dhcpd.conf
INTERFACES="eth0"
