Ansible-Tower--安装配置及破解

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.  Because RabbitMQ never
# communicates outside the cluster, a private CA and certificates will be
# created, and do not need to be supplied.
# rabbitmq_use_ssl=False

# Server-side SSL settings for PostgreSQL (when we are installing it).
# postgres_use_ssl=False
# postgres_ssl_cert=/path/to/pgsql.crt
# postgres_ssl_key=/path/to/pgsql.key

#开始安装
[root@tower ansible-tower-setup-bundle-3.6.2-1]# ./setup.sh

        else:

                if os.path.isdir('/opt/rh/cfme-gemset'):
                    pass
            try:

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
