实验目标
简单部署tomcat及安装java环境
实现步骤
编写salt的状态模块
[root@linux-node1 web]# pwd /srv/salt/base/web [root@linux-node1 web]# cat tomcat.sls jdk-install: pkg.installed: - name: java-1.8.0-openjdk #rpm包安装不需要添加环境变量 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
上传apache-tomcat-8.0.46到salt的文件管理目录下
[root@linux-node1 src]# ll /srv/salt/base/web/files/apache-tomcat-8.0.46.tar.gz -rw-r--r-- 1 root root 9352747 Oct 16 2017 /srv/salt/base/web/files/apache-tomcat-8.0.46.tar.gz
执行状态模块

总结
1.添加状态模块的时候，应该自己得先在别的机器上面跑一遍流程在添加
2.状态模块中- source: salt://web/files/apache-conf.d #支持ftp或者http上面 base环境的路径
3.使用的时候要先测试 test=True
4.ID 有不同表示方式
5.状态模块需要执行模块执行才能生效
6.相同的业务用目录进行分类管理
7.sls文件是从上往下按照顺序执行
8.一个ID下面一个状态只能出现一次
9.pkg是虚拟的包管理,在不同系统下面包的安装命令不同 比如 CentOS 和Ubuntu
10.watch 和watch_in require和require_in 在状态模块中可以统一用其中的一种
11.salt默认是有缓存的，可以无关紧要的配置重启进程刷新缓存
salt任务执行过程中不删除缓存目录里面的文件 缓存目录默认为/var/cache/salt
