在做持续交付这件事&＃xff0c;想必大家都是用jenkins这款程序来做基石。当然&＃xff0c;我们这次也是用jenkins作为承载工具&＃xff0c;jenkins强大的插件是有目共睹的&＃xff0c;有些ansible做起来不容易的事情交给jenkins反而简单有效。下面我会详细说明怎么持续交付tomcat应用。
希望本实验可以引导大家在持续交付的过程中使用ansible工具&＃xff0c;也希望本实验能帮助到有需要的人&＃xff0c;更希望给到大家一个简单的持续交付思想和启发。如想继续交流的&＃xff0c;还请加入QQ群&＃xff1a;425931784。
应用架构
本次使用的应用架构是常见的负载均衡实例。
软件版本
os&＃xff1a; centos 6.7 X64
ansible: 2.3.1.0
python: 2.6.6
ant: 10.1
java: 1.8.0_13
tomcat: 8.5.14
jenkins: 2.73
Ansible roles
- Ansible Role 系统环境 之【ant】
- Ansible Role 系统环境 之【java】
- Ansible Role 系统环境 之【iptables】
- Ansible Role WEB 之【tomcat】
- Ansible Role WEB 之【nginx】
- Ansible Role 持续集成 之【jenkins】
- Ansible Role 持续交付 之【deploy-tomcat】
服务器角色
| 主机 | 角色 |
|---|---|
| node1 | nginx,jenkins |
| node130 | tomcat |
| node131 | tomcat |
集群搭建
本次使用anisble playbook
---- hosts: node130 node131vars:- java_version: "1.8"- tomcat_version: "8.5.14"- iptables_allowed_tcp_ports: ["8080"]roles:- java- { role: tomcat, java_home: "/usr/java/jdk1.8.0_131" } - iptables - hosts: node1 vars: - java_version: "1.8" - nginx_version: "1.12.1" - nginx_upstreams: - name: upstremtest servers: - 192.168.77.130:8080 max_fails&＃61;2 fail_timeout&＃61;2 - 192.168.77.131:8080 max_fails&＃61;2 fail_timeout&＃61;2 - nginx_vhosts: - listen: 80 locations: - name: / proxy_pass: http://upstremtest - jenkins_version: "2.73" - jenkins_plugins_extra: - ansible - ansicolor - iptables_allowed_tcp_ports: ["80","8080"] roles: - ant - java - nginx - jenkins - iptables tasks: - name: install ansible package: name&＃61;ansible
怎么使用ansible roles&＃xff0c;请移步到 Ansible Role【怎么用&＃xff1f;】
确保正常访问以下服务&＃xff1a;
- nginx http://192.168.77.129/lework
- jenkins http://192.168.77.129:8080 帐号密码&＃xff1a;admin/admin
- tomcat http://192.168.77.130:8080/lework http://192.168.77.131:8080/lework
node1服务器操作
在服务器上配置ansible playbook
# cd /etc/ansible/
# cat tomcat-deploy.yml
---- hosts: allserial: 1roles:- deploy-tomcat# cat hosts
[node130]
192.168.77.130[node131]
192.168.77.131[testservers:children]
node130
node131[testservers:vars]
ansible_ssh_user&＃61;root
ansible_ssh_pass&＃61;123456# git clone https://github.com/kuailemy123/Ansible-roles.git /etc/ansible/roles/
# chown jenkins.jenkins /etc/ansible/
jenkins 操作
登录jenkins之后&＃xff0c;设置工具
点击“系统管理”&＃61;&＃61;》“Global Tool Configuration”
创建发布项目
配置参数化构建
配置源码仓库地址
repo: https://github.com/kuailemy123/AntSpringMVC.git
配置构建环境
配置编译
配置ansible
配置ansible变量
这里就不配置邮件通知了。
创建回滚项目
配置参数化构建
配置构建环境
配置ansible
配置
anisble变量
