使用ansible依次更新两个tomcat应用

2321321

一、环境说明
基础环境：
ansible服务端 192.168.1.120


ansible客户端 192.168.1.121


客户端环境：
/home/testuser # ll
drwxr-xr-x 9 root root     4096 Sep  8 17:21 apache-tomcat2
drwxr-xr-x 9 root root     4096 Sep  8 17:21 apache-tomcat3

在apache-tomcatX/webapps下分别是test2.war和test3.war两个包，apache-tomcat2的访问端口是8080

服务端环境：
源码编译安装了ansible

服务端的inventory配置文件/etc/ansible/hosts的配置
[slave]
192.168.1.121 ansible_ssh_port=22 ansible_ssh_user=root ansible_ssh_pass=XXXX

ansible_ssh_pass是root用户登录客户端192.168.1.121的登录密码

二、更新war包的playbook文件配置

- name: release war to ansible client
  hosts: slave
  remote_user: testuser
  vars:
    war_file: /etc/ansible/test.war
    tomcat2_root: /home/testuser/apache-tomcat2/webapps
    tomcat3_root: /home/testuser/apache-tomcat3/webapps
    newdir: /home/testuser/`date +%Y%m%d`
  tasks:
    - name: stop tomcat
      action: shell {{ tomcat2_root }}/../bin/catalina.sh stop --force
      tags:
       - tomcat2
    - name: create bakdir
      shell: mkdir {{ newdir }}
      tags:
       - tomcat2
    - name: move oldwar
      shell: mv {{ tomcat2_root }}/*.war {{ newdir }}
      tags:
       - tomcat2
    - name: replice newwar to tomcat2
      copy: src={{ war_file }} dest={{ tomcat2_root }}
      tags:
      - tomcat2
    - name: start tomcat2 service
      action: shell {{ tomcat2_root }}/../bin/catalina.sh start
      tags:
      - tomcat2
    - name: remove tomcat2 olddir
      shell: rm -rf {{ tomcat2_root }}/food2/
      tags:
      - tomcat2
    - name: sleep
      shell: sleep 40s
    - name: tomcat status
      shell: curl http://192.168.1.121:8080 &>/dev/null && echo YES || echo NO
      register: result
      tags:
       - tomcat3
    - name: begin tomcat3
      action: shell {{ tomcat3_root }}/../bin/catalina.sh stop --force
      when: result.stdout == "YES"
      tags:
       - tomcat3
    - name: move oldwar
      shell: mv {{ tomcat3_root }}/*.war {{ newdir }}
      when: result.stdout == "YES"
      tags:
       - tomcat3
    - name: replica newwar to tomcat3
      copy: src={{ war_file }} dest={{ tomcat3_root }}
      when: result.stdout == "YES"
      tags:
       - tomcat3
    - name: start tomcat3 service
      action: shell {{ tomcat3_root }}/../bin/catalina.sh start
      when: result.stdout == "YES"
      tags:
       - tomcat3
    - name: remove tomcat3 olddir
      shell: rm -rf {{ tomcat3_root }}/food3/
      when: result.stdout == "YES"
      tags:
       - tomcat3



说明：

shell: sleep 40s

shell: curl http://192.168.1.121:8080 &>/dev/null && echo YES || echo NO

上面的两行是为了确认第一个服务启动完成     

三、执行结果

/ansibletest/ansible-1.7.2/bin # ./ansible-playbook yml/tomcat-admin1.yml
