使用ansible依次更新两个tomcat应用
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 Sep8 17:21 apache-tomcat2
drwxr-xr-x 9 root root 4096 Sep8 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
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:> 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
