SaltStack本地管理无master模式-第八篇

Salt本地管理应用场景

1.在边缘节点服务器非常少没有Salt-master

2.零售店，电影院等弱网络环境没有Salt-master

3.快速部署单个服务没有Salt-master

实现

一，安装minion

[root@linux-node1 ~]#  yum install -y salt-minion 

二，更改minon配置文件,红色部分为新增加

[root@linux-node1 ~]# cat /etc/salt/minion
# defined below by setting it to "local". Setting a local file_client runs the
#file_client: remote #默认remote 使用的远程Master模式
file_client: local  #新增加一行 使用本地模式
....
# Example:
# file_roots:
#   base:
#     - /srv/salt/
#   dev:
#     - /srv/salt/dev/services
#     - /srv/salt/dev/states
#   prod:
#     - /srv/salt/prod/services
#     - /srv/salt/prod/states
#
file_roots:
  base:
    - /srv/salt/base
  dev:
    - /srv/salt/dev
  test:
    - /srv/salt/test
  prod:
    - /srv/salt/prod
.....

三，无需启动minion

[root@linux-node1 ~]# systemctl stop salt-minion

四，查看本地状态文件，以安装一个tomcat为列

[root@linux-node1 base]# cat /srv/salt/base/web/tomcat.sls 
jdk-install:
  pkg.installed:
    - name: java-1.8.0-openjdk

tomcat-install:
  file.managed:
    - name: /usr/local/src/apache-tomcat-8.0.46.tar.gz
    - source: salt://web/files/apache-tomcat-8.0.46.tar.gz
    - user: root
    - group: root
    - mode: 755
  cmd.run:
    - name: cd /usr/local/src && tar zxf apache-tomcat-8.0.46.tar.gz && mv apache-tomcat-8.0.46 /usr/local/ && ln -s /usr/local/apache-tomcat-8.0.46 /usr/local/tomcat
    - unless: test -L /usr/local/tomcat && test -d /usr/local/apache-tomcat-8.0.46

五，salt-call测试

[root@linux-node1 ~]# salt-call --local test.ping
local:
    True

六，使用salt-call执行本地状态文件

root@linux-node1 base]# salt-call --local state.sls web.tomcat

总结

1.本地管理模式，无需salt-master

2.本地管理模式，不需要启动minion服务
