salt haproxy 부하 균형 배치 실현

설정 환경:

환경 에서 nginx 와 apache 배치 스 크 립 트 에 접근 합 니 다. 이 글 은 haproxy 기능 만 수행 합 니 다.https://blog.csdn.net/u010489158/article/details/81744757
haproxy 자동 배치 실현
(1) yum 소스 확장

baseurl=http://172.25.1.250/rhel6.5
enabled=1
gpgcheck=1

(2) haproxy 스 크 립 트 저장 위치 만 들 기

[root@server1 ~]# cd /srv/salt/  
[root@server1 salt]# mkdir haproxy   #    haproxy       
[root@server1 salt]# cd haproxy/

(3) yum 원본 프로필 의 푸 시 스 크 립 트

[root@server1 haproxy]# vim yum.sls    #    yum    
yum-install:
  file.managed:                 #       
    - name: /etc/yum.repos.d/rhel-source.repo   # source      name   
    - source: salt://haproxy/file/rhel-source.repo
  cmd.run:    #  shell  
    - name: yum clean all

(4) haproxy 의 소스 코드 설치 스 크 립 트

[root@server1 haproxy]# vim make.sls    #haproxy     
include:
  - haproxy.yum        #  haproxy    yum.sls  
haproxy-install:       #  haproxy   
  pkg.installed:       #  yum      
    - pkgs:   #     
      - rpm-build
  file.managed:
    - name: /root/haproxy-1.6.11.tar.gz
    - source: salt://haproxy/file/haproxy-1.6.11.tar.gz
  cmd.run:      #  shell  
    - name: yum install rpm-build && cd /root && rpmbuild -tb haproxy-1.6.11.tar.gz && tar zxf haproxy-1.6.11.tar.gz && cd /rpmbuild/RPMS/x86_64/ && rpm -ivh haproxy-1.6.11-1.x86_64.rpm
    - create: /etc/haproxy     #             

(5) haproxy 사용자 의 스 크 립 트 만 들 기

[root@server1 users]# cd /srv/salt/users
[root@server1 users]# vim haproxy.sls  #  haproxy  
haproxy-group:   #      
  group.present:
    - name: haproxy
    - gid: 200

haproxy-user:  #     
  user.present:
    - name: haproxy
    - uid: 200
    - gid: 200
    - shell: /sbin/nologin
    - createhome: False
    - home: /usr/local/nginx

(6) haproxy 서비스의 시작 과 설정 파일 스 크 립 트

[root@server1 haproxy]# vim service.sls   #         
include:   #  haproxy  make.sls    users  haproxy.sls
  - haproxy.make
  - users.haproxy
/etc/haproxy/haproxy.cfg:     #      id, source        ID  
  file.managed:
    - source: salt://haproxy/file/haproxy.cfg
haproxy-service:   #  haproxy     
  service.running:
    - enable: True   #      
    - name: haproxy   #haproxy  
    - reload: True   #  watch           reload
    - watch:    #  file    
      - file: /etc/haproxy/haproxy.cfg
    - require:
      - user: haproxy

(8) 전역 푸 시 파일 을 작성 하고 모든 노드 를 원 클릭 으로 푸 시 합 니 다.

[root@server1 ~]# cd /srv/salt/
[root@server1 salt]# vim top.sls 
base:
  'server2':
    - haproxy.service
  'server3':
    - apache.install
  'server4':
    - nginx.service

[root@server1 salt]# salt '*' state.highstate   #    

(9) 테스트
< 1 > server 1 은 server 2 (haproxy) 를 방문 하여 httpd 와 nginx 의 폴 링 을 실현 합 니 다.

[root@server1 ~]# curl 172.25.1.2
this is apache
[root@server1 ~]# curl 172.25.1.2
this is nginx!!!!
[root@server1 ~]# curl 172.25.1.2
