一,创建states文件
在/srv/salt目录下创建jdk目录,并在jdk目录创建init.sls文件,init.sls文件内容如下:
jdk-file:
file.managed:
- source: salt://jdk/files/jdk1.6.0_39.tar.gz
- name: /usr/java/jdk1.6.0_39.tar.gz
- include_empty: True
jdk-install:
cmd.run:
- name: '/bin/tar -zxf jdk1.6.0_39.tar.gz && /bin/ln -s jdk1.6.0_39 latest '
- cwd: /usr/java
- unless: 'test -e jdk1.6.0_39'
- require:
- file: jdk-file
jdk-rmzip:
file.absent:
- name: /usr/java/jdk1.6.0_39.tar.gz
/root/.bashrc:
file.append:
- text:
- export JAVA_HOME=/usr/java/latest
- export PATH=$JAVA_HOME/bin:$PATH
上面sls文件需要引用jdk1.6.0_39.tar.gz文件,故需要下载jdk1.6.0_39.bin安装之后将其打包成jdk1.6.0_39.tar.gz拷贝到/srv/salt/jdk/files目录。
init.sls文件执行过程包括以下几个步骤:
jdk-file,将salt://jdk/files/jdk1.6.0_39.tar.gz文件拷贝到/usr/java
jdk-install,解压文件
jdk-rmzip,删除压缩包
/root/.bashrc,设置JAVA_HOME
修改top.sls文件(该步骤为可选),添加jdk.init:
base:
'*':
- jdk.init
测试运行
在master上运行下面命令,并观察运行结果:
[root@sk1 vagrant]# salt '*' state.sls jdk
sk2:

从上可以看出成功了4个,失败为0。
安装了jdk之后,需要重启minion(还需要修改minion启动脚本,让minion加载上系统环境变量,详细说明,见安装SaltStack和halite)才能通过下面脚本运行java相关的命令,如java、jps等等:
salt '*' cmd.run 'jps'
否则,你需要通过下面脚本来执行:
salt '*' cmd.run 'source /root/.bashrc ;jps'
二,设置pillar
将上面的jdk/init.sls文件修改为通过pillar引用变量
a.首先在/srv/pillar目录创建jdk目录,并在jdk目录下创建init.sls文件,内容如下:
jdk:
name: jdk1.6.0_39
srvpath: salt://jdk/files
homepath: /usr/java
b.在/srv/pillar/top.sls中添加jdk.init
base:
'*':
- jdk.init
c.修改/srv/salt/jdk/init.sls文件为从pillar引入变量,内容如下:
jdk-file:
file.managed:
- source: {{pillar['jdk']['srvpath']}}/{{pillar['jdk']['name']}}.tar.gz
- name: {{pillar['jdk']['homepath']}}/{{pillar['jdk']['name']}}.tar.gz
- makedirs: True
jdk-install:
cmd.run:
- name: 'unzip -q {{pillar['jdk']['name']}}.tar.gz'
- cwd: {{pillar['jdk']['homepath']}}
- unless: 'test -e {{pillar['jdk']['name']}}'
- require:
- file: jdk-file
jdk-rmzip:
file.absent:
- name: {{pillar['jdk']['homepath']}}/{{pillar['jdk']['name']}}.tar.gz
{{pillar['userhome']}}/.bashrc:
file.append:
- text:
- export JAVA_HOME={{pillar['jdk']['homepath']}}/{{pillar['jdk']['name']}}
- export PATH=$JAVA_HOME/bin:$PATH
d.参考上面,再次测试一遍
