2개월 만의 업로드....

너~무 바빴던 지난 2개월 (그리고 앞으로도 계속 바쁠것같다~ ㅠ)

힘든일도 있었고..  좋은일도 있었고  :-)

2개월간, 정리안하고 찍기만한 사진이 너무많아져서~ 당분간 사진은 안찍기로... (정리나해야지..)

인물사진 잘찍고싶다~

Constants with a leading 0 are interpreted as octal numbers.

You can remove the leading zero by parameter expansion:

hour=${hour#0}

or force base-10 interpretation:

$((10#$hour + 1))

rpm -iUvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

yum update -y

yum -y install docker-io

After doing these, i met a problem with Cgroup.

/cgroup/memory: No such file or directory

Starting cgconfig service: Error: cannot mount memory to /cgroup/memory: No such file or directory

/sbin/cgconfigparser; error loading /etc/cgconfig.conf: Cgroup mounting failed

Failed to parse /etc/cgconfig.conf                         [FAILED]

Then, edit "/etc/cgconfig.conf" as follows :

# memory = /cgroup/memory;

And start the cgroup service and docker

$ sudo service cgconfig start

$ sudo service docker start

Optionally, we can configure docker to start at every booting time as follows,

$ sudo chkconfig docker on
