我在ubuntu 14.04上安装了docker,它告诉我安装成功.然后我进去了sudo docker version,它回来了

Cannot connect to the Docker daemon. Is the docker daemon running on this host?
我进去了sudo service docker status,我知道了
docker start/running, process 8063
我试过sudo docker images和sudo docker info,我得到了同样的答复:
Cannot connect to the Docker daemon. Is the docker daemon running on this host?
我不知道为什么它返回这个,我试图拉ubuntu使用sudo docker pull ubuntu,并得到 …
我想在docker中部署我的python项目,我在requirments.txt中写道lxml>=3.5.0,因为项目需要lxml.这是我的dockfile:
FROM gliderlabs/alpine:3.3
RUN set -x \
&& buildDeps='\
python-dev \
py-pip \
build-base \
' \
&& apk --update add python py-lxml $buildDeps \
&& rm -rf /var/cache/apk/* \
&& mkdir -p /app
ENV INSTALL_PATH /app
WORKDIR $INSTALL_PATH
COPY requirements-docker.txt ./
RUN pip install -r requirements.txt
COPY . .
RUN apk del --purge $buildDeps
ENTRYPOINT ["celery", "-A", "tasks", "worker", "-l", "info", "-B"]
当我将它部署到docker时,我得到了这个:
*********************************************************************************
Could not find function xmlCheckVersion in library libxml2. Is libxml2 installed?
*********************************************************************************
error: …我的Dockerfile是：
FROM gliderlabs/alpine:3.3
RUN set -x \
&& buildDeps='\
python-dev \
py-pip \
build-base \
' \
&& apk --update add python py-lxml py-mysqldb $buildDeps \
&& rm -rf /var/cache/apk/* \
&& mkdir -p /app
ENV INSTALL_PATH /app
ENV TZ=Asia/Shanghai
WORKDIR $INSTALL_PATH
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
COPY requirements-docker.txt ./
RUN pip install -r requirements-docker.txt
COPY . .
RUN apk del --purge $buildDeps
ENTRYPOINT ["celery", "-A", "tasks", "worker", "-l", "info", "-B"]
我将时区设置为Asia/Shanghai，但它不起作用，并给了我有8小时偏差的UTC，结果是：
2016-01-24 …我正在尝试在 ubuntu 14.04 下的 Clion 中编写 CMakeList.txt，如下所示：
cmake_minimum_required(VERSION 2.8.3)
project(ify)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -pthread -std=c++11")
## System dependencies are found with CMake's conventions
find_package(Boost REQUIRED)
include_directories(
${catkin_INCLUDE_DIRS}
/usr/local/include
/usr/include
include
)
include_directories(
include/
)
link_directories(
/usr/local/lib
/usr/lib
libs/x64
/usr/lib/x86_64-linux-gnu
)
#set(SOURCE_FILES main.cpp)
#add_executable(ify ${SOURCE_FILES})
add_executable(ify main.cpp)
target_link_libraries(ify ${catkin_LIBRARIES}
libmsc.so
libasound.so
)
当我运行时它告诉我：

我搜索后尝试了一些方法：
1：像这样添加ldl：
