본 가이드는 OS 설치 및 기본 세팅 후, 매우 예외 없는 상황 및 환경에서 일반적인 시나리오로 CloudHub 기본 세팅 및 구동을 위해 빠르게 따라할 수 있도록 작성되었습니다.

따라서, 특별한 상황 즉, 이미 여러 종류의 App들이 설치 운용되고 있는 복합적 상황 등의 경우에는 정식 Installation guide를 참고 바랍니다.

사전 점검

OS

CentOS 7 x86_64 기준

방화벽 점검 및 세팅

SaltStack 설치

  1. SaltStack 저장소 등록

    $ yum install -y epel-release
$ rpm --import https://repo.saltproject.io/py3/redhat/7/x86_64/archive/3001.4/SALTSTACK-GPG-KEY.pub
$ curl -fsSL https://repo.saltproject.io/py3/redhat/7/x86_64/archive/3001.4.repo | sudo tee /etc/yum.repos.d/salt.repo
$ yum clean expire-cache

  2. Salt-Master, Salt-API, Salt-Minion 설치

    $ yum install -y salt-master salt-api salt-minion

  3. snetsystems/salt 모듈로 overwrite
    Copy $(git cloned path)/salt/modules/* to standard installed Salt module path(usually, /usr/lib/python3.6/site-packages/salt/modules)

    $ git clone https://github.com/snetsystems/salt.git
$ cp -rf salt/salt/modules/* /usr/lib/python3.6/site-packages/salt/modules/

  4. Config 설정

    1. Salt-Master의 Config 와 Salt-API의 Config 파일을 설정해야 합니다.

    2. Salt-Master : $ vim /etc/salt/master.d/master.conf

    3. 주의 Host에 여러 Interface가 있을 경우 Salt-Minion과 연결 가능한 네트워크 Interface IP로 설정해야 합니다.
      ex) interface: 61.254.65.58
      아래 예와 같이 any(0.0.0.0)로 설정해도 master ↔︎ minion 간 통신은 문제가 없으나,
      CloudHub UI에서 원하지 않는 IP로 표시될 수 있습니다.

      ## log_level ##
# One of 'garbage', 'trace', 'debug', info', 'warning'(default), 'error', 'critical'.
log_level: info

##### Primary configuration settings #####

# The address of the interface to bind to:

# The tcp port used by the publisher:

# Allow minions to push files to the master. This is disabled by default, for
# security purposes.
file_recv: True
 
#####      State System settings     #####
##########################################
# The state system uses a "top" file to tell the minions what environment to
# use and what modules to use. The state_top file is defined relative to the
# root of the base environment as defined in "File Server settings" below.
state_top: top.sls
 
#####      File Server settings      #####
##########################################
# Salt runs a lightweight file server written in zeromq to deliver files to
# minions. This file server is built into the master daemon and does not
# require a dedicated port.
 
# The file server works on environments passed to the master, each environment
# can have multiple root directories, the subdirectories in the multiple file
# roots cannot match, otherwise the downloaded files will not be able to be
# reliably ensured. A base environment is required to house the top file.
file_roots:
  base:
    - /srv/salt/prod

    - /srv/salt/qa
    - /srv/salt/prod
  dev:
    - /srv/salt/dev
    - /srv/salt/qa
    - /srv/salt/prod
 
# File Server Backend
#
# Salt supports a modular fileserver backend system, this system allows
# the salt master to link directly to third party systems to gather and
# manage the files available to minions. Multiple backends can be
# configured and will be searched for the requested file in the order in which
# they are defined here. The default setting only enables the standard backend
# "roots" which uses the "file_roots" option.
fileserver_backend:
  - roots
 
#####        Security settings       #####
##########################################
# The external auth system uses the Salt auth modules to authenticate and
# validate users to access areas of the Salt system.
external_auth:
  pam:
    saltdev:
      - .*
      - '@runner'
      - '@wheel'
      - '@jobs'
 
# Allow eauth users to specify the expiry time of the tokens they generate.
# A boolean applies to all users or a dictionary of whitelisted eauth backends
# and usernames may be given.

  pam:
    - saltdev

#####        API Server settings     #####
##########################################
rest_cherrypy:
  port: 8000
  disable_ssl: True

    4. Salt-Minion : $ vim /etc/salt/minion.d/minion.conf

      ## log_level ##
# One of 'garbage', 'trace', 'debug', info', 'warning'(default), 'error', 'critical'.
log_level: info
master: <master ip address>
id: <유일한 minion id 설정해야 하며, 생략 시, hostname = minion id>

  5. 계정 생성 및 패스워드 설정
    아래 추가된 password는 추후 salt-api authentication을 위한 pam_token를 발급 받는데 쓰이므로, 잘 기억해두어야 합니다.

    $ useradd saltdev
$ passwd <password>
Changing password for user saltdev.
New password:

  6. 서비스 시작

    $ systemctl enable salt-master
$ systemctl start salt-master

$ systemctl enable salt-api

CloudHub Portal UI 초기 설정

  1. 로그인 창에서 Sign up(가입) 합니다.

  2. 로그인 후, 아래와 같이 초기 설정에서 단계 별로 적절한 값으로 설정합니다.

    초기 설정으로는 InfluxDB가 설치된 host IP 정도만 맞게 설정하면 됩니다.
    Connection Name는 Database(=Group) Name과 동일하면 편리합니다.

    Add Connection → Next를 반복 클릭하여 마무리 합니다.

  3. 아래 메뉴 화면에서 Group을 추가합니다.

  4. “Agent Configuration > Minions” 메뉴 화면에서 등록된 minion을 Operation 버튼을 통해 “Accept”합니다.

  5. 설치하고자 하는 minion host를 선택하고 콤보박스에서 telegraf를 선택 후, INSTALL 합니다.

  6. Group을 지정한 후, [[outputs.influxdb]]을 설정한 후, Test -> Apply 합니다.

    그 외 필요한 설정은 위 그림의 Plugins 리스트에서 참고하거나, https://github.com/snetsystems/telegraf#input-plugins 를 참고하여 추가하도록 합니다.
