一、安装前环境

Centos 7 最小化安装 | 4G内存 | 100GB硬盘

注：Ansible-Tower目前支持7.4+的版本，可以使用yum update -y命令更新

同时机器一定要联网，因为执行./setup的时候会联网安装很多的依赖包，安装速度和你的网速有关

二、安装Ansible
1.安装Ansible的epel源
yum install -y http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
yum update -y
2.清空缓存，安装Ansible
yum clean all
yum install -y ansible
至此Ansible安装成功

注意，将centos的yum源，更换成国内的比如163,阿里源。不然会出现软件不能下载问题。

三、安装Ansible-Tower
1.下载解压所需的安装包
cd /home
yum install -y wget
wget http://releases.ansible.com/ansible-tower/setup/ansible-tower-setup-latest.tar.gz
tar zxvf ansible-tower-setup-latest.tar.gz
2.移动安装包到/usr/local下
mv ansible-tower-setup-3.6.3/ /opt/ansible-tower

3.配置inventory文件

  进入/opt/ansible-tower目录下， 更改配置如下：

# cat inventory
[tower]
localhost ansible_connection=local

[database]

[all:vars]
admin_password='admin' #增加，默认无

pg_host=''
pg_port=''

pg_database='awx'
pg_username='awx'
pg_password='awx' #增加，默认无

rabbitmq_username=tower
rabbitmq_password='tower' #增加，默认无
rabbitmq_cookie=cookiemonster

就是需要增加三个密码。

4.安装Ansible-Tower
安装前先创建/var/log/tower的日志目录，不然会报错
mkdir -p /var/log/tower
删除之前下载的epel源
rm -rf /etc/yum.repos.d/e*

cd /usr/local/ansible-tower
./setup
安装过程中会要求输入密码，那个密码是之后登陆图形化界面的密码，当安装出现如下图的时候，代表已经安装成功

添加防火墙例外，关闭selinux，访问服务器地址即可

firewall-cmd --permanent --zone=public --add-port=80/tcp
systemctl restart firewalld.service

setenforce 0
vim /etc/sysconfig/selinux
将SELINUX的状态改为
SELINUX=disabled

五、安装完成后设置
1.遇到打开之后左上角已经显示出标签页，页面中没有任何选项的，请更换浏览器尝试一下

报错: ansible-tower包打不到
TASK [packages_el : Install the Tower RPM.] ************************************

fatal: [localhost]: FAILED! => {“changed”: false, “failed”: true, “msg”: “No package matching ‘ansible-tower == 3.0.3’ found available, installed or updated”, “rc”: 126, “results”: [“No package matching ‘ansible-tower == 3.0.3’ found available, installed or updated”]}

to retry, use: --limit @/root/ansible-tower-setup-3.0.3/install.retry

PLAY RECAP *********************************************************************

localhost : ok=38 changed=1 unreachable=0 failed=1

而根据自动生成的repo，发现http://releases.ansible.com/ansible-tower/setup/ 该仓库是有对应版本的包的。只是enable=0被禁用了。
解决办法:
手动建一个repo,避免修改后被覆盖
cat >/etc/yum.repos.d/Ansible-Tower.repo <<EOF
[Ansible-Tower]

name=Ansible Tower Repository - $releasever $basearch

baseurl=http://releases.ansible.com/ansible-tower/rpm/epel-7-$basearch

enabled=1

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ansible-release

EOF

再次执行setup.sh后成功安装并运行ansible-tower

如果有些包装不上，可以自己下载好后再安装RPM包。

安装好后会有提示:
