Salt-Master, Salt-API, Salt-Minion 설치
Code Block
language bash
$ yum install -y salt-master salt-api salt-minion
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)
Code Block
language bash
$ git clone https://github.com/snetsystems/salt.git $ cp -rf salt/salt/modules/* /usr/lib/python3.6/site-packages/salt/modules/

Config 설정

Salt-Master의 Config 와 Salt-API의 Config 파일을 설정해야 합니다.
Salt-Master : $ vim /etc/salt/master.d/master.conf

Status

colour	Red
title	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.

#####      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 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.
