- host  중에 ubuntu 에서 에러남

[DEPRECATION WARNING]: Distribution Ubuntu 18.04 on host tnode2-ubuntu.exp.com should use /usr/bin/python3, but is using /usr/bin/python for backward compatibility with prior Ansible releases. A future Ansible release will default to using the discovered platform python for this host. See https://docs.ansible.com/ansible/2.9/reference_appendices/interpreter_discovery.html for more information. This feature will be removed in version 2.12. Deprecation warnings can be disabled by setting deprecation_warnings=False in ansible.cfg.

[지원 중단 경고]: 호스트 tnode2-ubuntu.exp.com의 배포 Ubuntu 18.04는 /usr/bin/python3을 사용해야 하지만 이전 Ansible 릴리스와의 하위 호환성을 위해 /usr/bin/python을 사용하고 있습니다.
향후 Ansible 릴리스에서는 기본적으로 이 호스트에 대해 검색된 플랫폼 Python을 사용하게 됩니다.
자세한 내용은 https://docs.ansible.com/ansible/2.9/reference_appendices/interpreter_discovery.html을 참조하세요.
이 기능은 버전 2.12에서 제거됩니다.
ansible.cfg에서 deprecation_warnings=False를 설정하여 사용 중단 경고를 비활성화할 수 있습니다.

Linux CentOS 7버전에서 Python3 설치 및 버전 변경 

1. python3설치
2. python2.7에서 python 3.6 버전 변경

# python3 설치 

# yum install python3​

# python 설치버전 및 경로 확인  (ver 2.7.5)

# python -V
Python 2.7.5

# which python
/usr/bin/python​

# python3 설치버전 및 경로 확인 (ver 3.6.12)

# python3 -V
Python 3.6.8

# which python3
/usr/bin/python3

리눅스에서 어떤 파이선 버젼 사용하고 있는지 확인

# update-alternatives --config python​

  (아무것도 안나오면 설정이 안되어 있음)

파이선 등록 

# update-alternatives --install /bin/python python /usr/bin/python2 1
# update-alternatives --install /bin/python python /usr/bin/python3 2

파이선 버젼 프로그램 선택 확인

# update-alternatives --config python​

*+2 번 선택

# python -V
# python3 -V​

둘다 Python 3.6.8 인지 확인

파이선 잘못 등록했을때 삭제  

# update-alternatives --remove python "/// 잘못 설정한 경로"

# update-alternatives --remove python /usr/bin/python3
# update-alternatives --remove python /bin/python2.7
# update-alternatives --remove python /opt/rh/rh-python36/root/usr/bin/python

#  Ansible Server에서 ssh-keygen을 실행함
# ssh-keygen

# ssh-copy-id root@192.168.56.54
# ssh-copy-id root@192.168.56.57
( 서버에서 작업을 하고 node가 3대 이므로 3대 반복 작업)

o Ansible를 이용한 서버 자동화 테스트를 위하여 PC 및 서버 환경 설정방법에 대한 설명입니다.

- PC에 테스트를 위해서 Virtualbox와 Vagrant를 설치하고
- 테스트 서버를 4대 설치합니다
   ... Ansible SERVER(CentOS) 1대, Ansible NODE(CentOS, Ubuntu, Redhat) 3대

o  해당 Ansible 자동화 테스트는
"컨테이너 인프라 환경 구축을 위한 쿠버네티스/도커 (조훈 저자, 길벗)"  
"앤서블로 시작하는 인프라 자동화 (장현정 저자, 한빛미디어)"을
참조하여 작성 및 테스트 예정입니다.. 

먼저 PC에 가상화를 돌리기 위한 virtualbox와  VM 이미지 다운로드 vargrant 를 설치합니다.

 https://www.vagrantup.com/

https://www.virtualbox.org/

서버 설치 계획 

테스트는 아래책 들을 기준으로 했습니다 

https://www.yes24.com/Product/Goods/102099414

- 앤서블로 시작하는 인프라 자동화에 있는 소스자료   https://github.com/naleejang/Easy-Ansible

 
https://app.vagrantup.com/boxes/search 에 관련 서버 설치정보 확인

o 웹페이지에 centos/8 vargrant 파일을 검색합니다.

o vagrantfiel 에 다운로드할 OS 정보를 확인합니다.  config.vm.box = " generic/centos8"

   ubuntu, RHEL 로 똑같습니다.

 
C:\HashiCorp\Vagrantfile 
 

Vagrant 서버 이미지 및 Vagrantfile 

# Vagrant 파일은 해당링크 https://hwpform.tistory.com/74 (실습하게 좋은 vagrant 파일)

# 해당 vagrantfiel을  C:\HashiCorp\Vagrantfile 에 복사해서

# vagrant up 할때변경된 Vagrantfile OS가 적용안되어  Vagrant.exe 삭제,  C:\HashiCorp\ 폴더 삭제 반복
 
# 보통 Vagrant 다운받은 OS root 패스워드는 "vagrant" 이나 root 패스워드가 안먹힘
CentOS, Ubuntu 는  vagrant/vagrant User 로 로그인 하여 root 패스워드 변경
 
$ sudo passwd root  
 
# RHEL 8는 위와 같은 방식으로 패스워드 변경이 안되어서
https://www.lesstif.com/system-admin/centos-8-rhel-8-reset-root-password-in-centos-8-86311229.html 

방식으로 적용하여 패스워드를 변경함

Ansible-CMDB & WEB-Server 만들기 

# yum install nginx -y   
 
- Ansible Server : 192.168.56.50 이고
- /usr/share/nginx/html/index.html       / WEB-server html 경로  
 
- page 확인

Ansible-cmdb 설치

https://ansible-cmdb.readthedocs.io/en/latest/installation                     * 설치주소 참조
 
# git clone https://github.com/fboender/ansible-cmdb.git                       *  git으로 설치함
   /usr/local/lib/ansible-cmdb                                                                    * 왼쪽 경로로 디렉토리가 생성됨

# cd /usr/local/lib/ansible-cmdb

# sudo bash -c ". build.sla && install"                                                       * ansible-cmdb 설치파일 
   Installed in /usr/local/

   /usr/local/lib/ansible-cmdb/ansible-cmdb.py                                           * 이게 설치파일인가 보다

# /usr/bin/./python /usr/local/lib/ansible-cmdb/ansible-cmdb.py                 * 파이선으로 돌리라고 함
  
# cd /usr/local/lib/ansible-cmdb                                                                   * 이 경로로 가서
 
# mkdir out                                                                                                   * out 디렉토리로 생성

$ ansible -m setup --tree /usr/local/lib/ansible-cmdb/out/ all   (vagrant 계정으로)
  위 명령을 root로 실행하니 ssh_keyscan 값이 없어서 에러남 
  vagrant 계정으로 ssh_keyscan 으로 생성되어 있으므로 vargant 스크립트 돌림

 

# ansible-cmdb -i /etc/ansible/hosts out/ > /usr/share/nginx/html/ansible-cmdb.html 
                                                                                                                      * cmdb 데이터를 web서버 경로로 생성
   /usr/share/nginx/html/   html 경로 퍼미션을 일단 777로 하고 root로 돌림
   (vagrant 계정이로 돌리니 html 디렉토리 퍼미션 에러,,일단 퍼미션은 나중에 맞추기로 함)

# http://192.168.56.50/ansible-cmdb.html 파일 확인

# 호스트 서버 ip를 클릭하면 # ansible -m setup 셋업으로 추출된 정보가 표출됨
