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
