篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了利用 Ansible 来做 tomcat 应用的持续交付相关的知识，希望对你有一定的参考价值。

在做持续交付这件事，想必大家都是用 Jenkins 这款程序来做基石。当然，我们这次也是用 Jenkins作为承载工具，Jenkins强大的插件是有目共睹的，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。

应用架构

本次使用的应用架构是常见的负载均衡实例。

利用 Ansible 来做 tomcat 应用的持续交付

软件版本

os：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

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 node131
  vars:
   - 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=2 fail_timeout=2
       - 192.168.77.131:8080 max_fails=2 fail_timeout=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=ansible

确保正常访问以下服务：

nginx http://192.168.77.129/lework
jenkins http://192.168.77.129:8080 帐号密码：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: all
  serial: 1
  roles:
   - deploy-tomcat

# cat hosts
[node130]
192.168.77.130

[node131]
192.168.77.131

[testservers:children]
node130
node131

[testservers:vars]
ansible_ssh_user=root
ansible_ssh_pass=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，设置工具
点击“系统管理”==》“Global Tool Configuration”

至此，持续交付实验就完成了，但是持续之路还是很漫长了。望大家永远前进。大家也可在发的过程中，测试发布是否是灰度发布。

for i in `seq 10000`;do curl -s -I http://192.168.77.129 | head -1;sleep 1;done;
