前言：因为我们使用state.sls进行安装，所以你可能需要先熟悉下state.sls的语法
state语法参考
- 开始先看下salt-master的配置
> tail -10 /etc/salt/master
# salt state执行时候的根目录
file_roots:
base:
- /srv/salt/base
# 设置pillar 的根目录
pillar_roots:
base:
- /srv/salt/pillar
# master自动接收客户端的验证
auto_accept: True
salt的主目录在 /srv/salt/base；minion端为docker-100；
- salt-jdk-tomcat 目录结构
> tree /srv/salt/base/
/srv/salt/base/
└── package

└── init.sls
5 directories, 6 files
1. 因为tomcat运行需要jdk，所以先安装jdk环境
> cat /srv/salt/base/package/jdk1_8/init.sls
jdk-file:
file.managed:
- name: /tmp/jdk-8u74-linux-x64.tar.gz
- source: salt://package/jdk1_8/files/jdk-8u74-linux-x64.tar.gz
- user: root
- group: root
- mode: 755
jdk-install:
cmd.run:
- cwd: /tmp
- names:
- tar zxf jdk-8u74-linux-x64.tar.gz -C /usr/local
- ln -s /usr/local/jdk1.8.0_74 /usr/local/java
- chown -R root:root /usr/local/java
- unless: test -d /usr/local/jdk1.8.0_74
- require:
- file: jdk-file
jdk-config:
file.append:
- name: /etc/profile
- text:
- "#############JAVA ENVIRONMNET################"
- "export JAVA_HOME=/usr/local/java"
- "export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH"
- "export CLASSPATH=.$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib"
运行看看效果

- name: /tmp/apache-tomcat-7.0.63.tar.gz

file.managed:
- name: /usr/local/tomcat7/bin/catalina.sh

- group: root
include表示关联上面的jdk,安装tomcat前会先去安装jdk，server.xml和catalina.sh分别加了如下配置
- server.xml
# 绑定客户端内网ip，并调整tomcat参数，下面只给出修改部分，完整配置得补全
<Connector port="8080" protocol="HTTP/1.1"
address="{{grains['ipv4'][0]}}" #绑定本机内网ip

minSpareThreads="50"
maxSpareThreads="150"
minProcessors="100"
maxProcessors="1000"
acceptCount="1000"
redirectPort="8443" />
- catalina.sh
# 根据客户端内存配置动态设置 tomcat运行内存，只给出修改部分，完整配置得补全
#!/bin/sh
{% if grains['mem_total'] > 7000 %}

我们的tomcat已经被安装到了 /usr/local/tomcat7
Tips：
下面主要讲一下 cmd.run 模块：
– name: 这个name是执行脚本和命令的名子
– onlyif: 测试命令，如果执行命令返回为True cmd.run的命令才会被执行
– unless: 正好与onlyif相反，为True不执行 为false才有可能执行
– request: 这个应该很好理解，cmd.run运行，必须以安装了它指定的包为前提的
当然这里面还有一些其他参数，我这里只是用了两三条，下面再列举一些：
– cwd: 执行命令当前目录位置，默认/root
– user: 执行命令用户(root为默认）
– group: 执行命令组（root为默认）
– shell: 执行命令使用的shell
– env: 执行命令的环境设置
– umask: 运行命令时umask设置
– output_loglevel:执行命令输出日志的级别，其中特殊的设置为quiet,那么就不输出日志了
– timeout: 执行命令超时时间
自此，salt安装tomcat完毕
