一、ansible-tower简介
1）公司中实现运维自动化的架构中主要用到ansible，ansible脚本在部署服务器指令行中显得不太直观。Ansible-Tower（之前叫做awx）是将ansible的指令界面化，简明直观，简单易用。
2）Ansibke-tower其实就是一个图形化的任务调度，复杂服务部署，IT自动化的一个管理平台，属于发布配置管理系统，支持Api及界面操作，Django编写。
3）Ansible-tower可以通过界面从github拉取最新playbook实施服务部署，提高生产效率。当然它也提供一个RESET API和命令行的CLI以供python脚本调用

二、ansible-tower安装及配置
[root@tower ~]# cd /opt/ [root@tower opt]# wget https://releases.ansible.com/ansible-tower/setup-bundle/ansible-tower-setup-bundle-3.6.2-1.el7.tar.gz [root@tower opt]# tar xf ansible-tower-setup-bundle-3.6.2-1.el7.tar.gz [root@tower opt]# cd ansible-tower-setup-bundle-3.6.2-1/ [root@tower ansible-tower-setup-bundle-3.6.2-1]# ls backup.yml bundle group_vars install.yml inventory licenses README.md rekey.yml restore.yml roles setup.sh [root@tower ansible-tower-setup-bundle-3.6.2-1]# vim inventory [tower] localhost ansible_connection=local [database] [all:vars] admin_password='tower' #tower登录密码 pg_host='' pg_port='' pg_database='awx' pg_username='awx' pg_password='tower' pg_sslmode='prefer' # set to 'verify-full' for client-side enforced SSL rabbitmq_username=tower rabbitmq_password='tower' rabbitmq_cookie=cookiemonster # Isolated Tower nodes automatically generate an RSA key for authentication; # To disable this behavior, set this value to false # isolated_key_generation=true # SSL-related variables # If set, this will install a custom CA certificate to the system trust store. # custom_ca_cert=/path/to/ca.crt # Certificate and key to install in nginx for the web UI and API # web_server_ssl_cert=/path/to/tower.cert # web_server_ssl_key=/path/to/tower.key # Use SSL for RabbitMQ inter-node communication.

Restarting Tower
Redirecting to /bin/systemctl stop rh-postgresql10-postgresql.service
Redirecting to /bin/systemctl stop rabbitmq-server.service
Redirecting to /bin/systemctl stop nginx.service
Redirecting to /bin/systemctl stop supervisord.service
Redirecting to /bin/systemctl start rh-postgresql10-postgresql.service
Redirecting to /bin/systemctl start rabbitmq-server.service
Redirecting to /bin/systemctl start nginx.service
Redirecting to /bin/systemctl start supervisord.service
#访问https://10.0.0.203/#/license
四、运行测试项目
playbook将在github上创建，Ansible Tower拉取执行，Ansible Tower的playbook默认存在 /var/lib/awx/projects/
1）创建host登录凭据
2）在github中添加playbook项目
3）在Ansible Tower添加拉取github项目的凭据
4）创建project
保存后Ansilble Tower会自动运行一次Update，如果要手动运行，点击列表中的刷新按钮。当github上yml文件被更新或者新增后需要点击一下刷新按钮，否则JOB执行得还是原来的yml
此时在Ansible Tower服务器的/var/lib/awx/projects/目录下已经有git拉下来的完整文件结构
5）创建主机清单
6）创建任务模板
7）运行模板
点击右侧日志中change几行可以看到详细信息
五、安装tomcat8测试
1）编写playbook
---
- hosts: all
remote_user: root
tasks:
- name: "copy files to remote host"
copy:
src={{ item.src }}
dest={{ item.dest }}
with_items:
- src: /usr/local/src/jdk-8u162-linux-x64.rpm
dest: /usr/local/
- src: /usr/local/src/apache-tomcat-8.0.38.tar.gz
dest: /usr/local/
- name: "install jdk"
yum:
name: /usr/local/jdk-8u162-linux-x64.rpm
state: present
- name: "install tomcat8"
shell: cd /usr/local/ && tar xf apache-tomcat-8.0.38.tar.gz
- name: "rename file"
shell: mv /usr/local/apache-tomcat-8.0.38 /usr/local/tomcat8
- name: "start tomcat"
shell: 'nohup /usr/local/tomcat8/bin/startup.sh &'2）创建inventory
3）创建project
4）创建模板
5）运行模板
6）浏览器测试tomcat
