最简单的sls state
vim /srv/salt/top.sls #正则匹配 base: '*': - webserver vim /srv/salt/webserver.sls lynx: # 标签定义 pkg: # state declaration - installed # function declaration 第一行被称为(ID declaration) 标签定义,在这里被定义为安装包的名。注意:在不同发行版软件包命名不同,比如 fedora 中叫httpd的包 Debian/Ubuntu中叫apache2 第二行被称为(state declaration)状态定义, 在这里定义使用(pkg state module) 第三行被称为(function declaration)函数定义, 在这里定义使用(pkg state module)调用 installed 函数 salt '*' state.highstate -v test=True salt '*' state.highstate 2.9 配置管理从这里开始 p27 1.查看支持的所有states 列表 salt 'gitlabzbx' sys.list_state_modules gitlabzbx: - alias - alternatives - apt - archive - artifactory - beacon - bigip 5. 从一个简单的实例理解states cat /srv/salt/one.sls /tmp/foo.conf: file.managed: - source: salt://foo.conf - user: root - group: root - mode: 644 - backup: minion root@myxp:~# echo "salt books" > /srv/salt/foo.conf 这样就把 master上的 /src/salt/foo.conf 分发到 minon的 /tmp/foo.conf root@myxps:/srv/salt# salt '*' state.sls one zbxAgent: ---------- ID: /tmp/foo.conf Function: file.managed Result: True Comment: File /tmp/foo.conf updated Started: 08:31:01.737749 Duration: 45.764 ms Changes: ---------- diff: New file mode: 0644 Summary for zbxAgent ------------ Succeeded: 1 (changed=1) Failed: 0 ------------ Total states run: 1 Total run time: 45.764 ms gitlabzbx: ---------- ID: /tmp/foo.conf
salt系统初始化例子
https://github.com/evan886/saltops
下面介绍 使用top.sls 入口文件同时对多台服务器进行的配置管理
salt-master --log-level=debug
环境配置 配置file_roots and pillar_roots 正式例子
# Example: 注意 各空两格下去 级级下去 我搞了半天 呀 一开始 file_roots: base: # - /srv/salt/base # dev: # - /srv/salt/dev/services # - /srv/salt/dev/states prod: - /srv/salt/prod/ # - /srv/salt/prod/states pillar_roots: base: - /srv/pillar/base # prod: - /srv/pillar/prod mkdir -p /srv/salt/base /srv/salt/prod mkdir -p /srv/pillar/base /srv/pillar/prod /etc/init.d/salt-master restart
系统初始化
dns config
cat /srv/salt/base/init/dns.sls /etc/resolv.conf: file.managed: - source: salt://init/files/resolv.conf - user: root - group: root - mode: 644 cat /srv/salt/base/init/files/resolv.conf # Generated by NetworkManager nameserver 192.168.88.1 nameserver fd67:f843:530::1
history记录时间
cat /srv/salt/base/init/history.sls /etc/bashrc: file.append: - text: - HISTTIMEFORMAT="%F %T `whoamii` " cmd.run: - name: source /etc/bashrc # or cat /srv/salt/base/init/history.sls /etc/profile: file.append: - text: - HISTTIMEFORMAT="%F %T `whoamii` " cmd.run: - name: source /etc/bashrc
初始化环境引用
cat /srv/salt/base/init/env_init.sls include: - init.dns - init.history tree /srv/salt/base/ /srv/salt/base/ ├── init │ ├── dns.sls │ ├── dns.slsbak │ ├── env_init.sls │ ├── files │ │ └── resolv.conf │ └── history.sls ├── top.sls cat /srv/salt/base/top.sls base: '*': - init.env_init salt '*' state.highstate test=True salt '*' state.highstate

trouble shooting
trouble Rendering SLS 'base:init.dns' failed: mapping values are not allowed here; line 2 cat init/dns.sls /etc/resolv.conf: 少了这个的原因 ? 老报错 不有 第二行 要空4格 这书本 看起来是空了3格 file.managed: - source: salt://init/files/resolv.conf - user: root - group: root - mode: 644 参考一下别人发现的错
