2.ansible以roles的方式安装tomcat

cat /etc/ansible/roles/tomcat/tasks/main.yml- name: install package  yum: name={
   { item }} state=latest  with_item:  - tomcat  - tomcat-admin-webapps  - tomcat-webapps  - tomcat-docs-webapp  when: ansible_os_family == "RedHat"- name: start tomcat  service: name=tomcat state=started enabled=true# 安装jdkmkdir -pv /etc/ansible/roles/jdk/{files,templetes,tasks,vars,handlers,meta,default}# 系统安装的openjdk不用手动提供java家目录cat /etc/ansible/roles/jdk/tasks/main.yml- name: install openjdk  yum: name=java-{
   { version }}-openjdk-devel state=latest- name: create env file  copy: src=java.sh dest=/etc/profile.d/cat files/java.shexport JAVA_HOME=/usr
