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=https://www.linuxidc.com/Linux/2017-03/{{ war_file }} dest=https://www.linuxidc.com/Linux/2017-03/{{ 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 :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=https://www.linuxidc.com/Linux/2017-03/{{ war_file }} dest=https://www.linuxidc.com/Linux/2017-03/{{ 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 :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
