實驗目標
簡單部署tomcat及安裝java環境
實現步驟
編寫salt的狀態模塊
[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包安裝不需要添加環境變量 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
上傳apache-tomcat-8.0.46到salt的文件管理目錄下
[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
執行狀態模塊

總結
1.添加狀態模塊的時候，應該自己得先在別的機器上面跑一遍流程在添加
2.狀態模塊中- source: salt://web/files/apache-conf.d #支持ftp或者http上面 base環境的路徑
3.使用的時候要先測試 test=True
4.ID 有不同表示方式
5.狀態模塊需要執行模塊執行才能生效
6.相同的業務用目錄進行分類管理
7.sls文件是從上往下按照順序執行
8.一個ID下面一個狀態只能出現一次
9.pkg是虛擬的包管理,在不同系統下面包的安裝命令不同 比如 CentOS 和Ubuntu
10.watch 和watch_in require和require_in 在狀態模塊中可以統一用其中的一種
11.salt默認是有緩存的，可以無關緊要的配置重啟進程刷新緩存
salt任務執行過程中不刪除緩存目錄里面的文件 緩存目錄默認為/var/cache/salt
