部署

設置主機信息

sed -i "s#password=''#password='admin'#g" inventory
sed -i "s#host=''#host='127.0.0.1'#g" inventory 
sed -i "s#port=''#port='5432'#g" inventory 

修改yum源

sed -i 's#dl.fedoraproject.org/pub#mirrors.ustc.edu.cn#g' roles/packages_el/defaults/main.yml
sed -i 's/#baseurl=/baseurl=/g' roles/packages_el/files/epel-6.repo
sed -i 's/mirrorlist=/#mirrorlist=/g' roles/packages_el/files/epel-6.repo
sed -i 's#download.fedoraproject.org/pub#mirrors.ustc.edu.cn#g' roles/packages_el/files/epel-6.repo

yum -y install centos-release-scl-rh centos-release-scl
sed -i 's#mirror.centos.org#centos.ustc.edu.cn#g' /etc/yum.repos.d/CentOS-SCLo-scl.repo
sed -i 's#mirror.centos.org#centos.ustc.edu.cn#g' /etc/yum.repos.d/CentOS-SCLo-scl-rh.repo
yum -y install supervisor

安裝ansible

./setup.sh

在
TASK [awx_install : Migrate the Tower database schema (may take awhile when upgrading).] ***
這一步會出現錯誤，提示信息是數據庫連接不上

啟動postgresql

service postgresql-9.4 initdb
service postgresql-9.4 start

創建用戶

su - postgres
psql
CREATE ROLE awx CREATEDB PASSWORD 'admin' LOGIN; 
\q

sed -i 's#peer#md5#g' /var/lib/pgsql/9.4/data/pg_hba.conf
sed -i 's#ident#md5#g' /var/lib/pgsql/9.4/data/pg_hba.conf
service postgresql-9.4 restart

測試awx用戶連接，輸入密碼連接，并創建數據庫

psql -U awx -d postgres -h 127.0.0.1
create database awx;
\q

再次./setup.sh進行安裝tower

Web配置

訪問web頁面

https://192.168.77.128/#/

用戶名/密碼為admin admin

導入license
沒有的話，點擊REQUEST LICENSE，去官方申請免費試用。

提交license后，就進入了DASHBOARD頁面啦

Tower無限hosts的License修改

僅供實驗測試使用，切勿挪作他用。

下載反編譯工具： http://sourceforge.net/projects/easypythondecompiler/

反編譯task_engine.pyc文件

find / -name task_engine.pyc
/var/lib/awx/venv/tower/lib/python2.7/site-packages/awx/main/task_engine.pyc

Paste_Image.png

反編譯后的文件為task_engine.pyc_dis，文件重命名為task_engine.py

修改內容

89行和186行代碼
available_instances = int(self.attributes['instance_count']) 為
available_instances = 10000

Paste_Image.png

Paste_Image.png

247行代碼，把相應的功能由False改為True

Paste_Image.png

刪除task_engine.pyc task_engine.pyo ，將修改后的task_engine.py文件上傳到tower上，重啟tower服務

rm -f  /var/lib/awx/venv/tower/lib/python2.7/site-packages/awx/main/task_engine.py*
cp task_engine.py /var/lib/awx/venv/tower/lib/python2.7/site-packages/awx/main/
ansible-tower-service restart

查看license信息

安裝時遇到的錯誤

fatal: [localhost]: FAILED! => {"changed": false, "failed": true, "msg": "This machine does not have sufficient RAM to run Ansible Tower."}

解決：機器內存不足，增加內存

fatal: [localhost]: FAILED! => {"changed": false, "failed": true, "msg": "no service or tool found for: supervisord"}

解決：yum -y install supervisor

出現Is the server running on host \"localhost\" (127.0.0.1) and accepting\n\tTCP/IP connections on port 5432?

是postgresql服務沒啟動

service postgresql-9.4 initdb
service postgresql-9.4 start

# 創建用戶
su - postgres
psql
CREATE ROLE awx CREATEDB PASSWORD 'admin' LOGIN; 
\q
exit

sed -i 's#peer#md5#g' /var/lib/pgsql/9.4/data/pg_hba.conf
sed -i 's#ident#md5#g' /var/lib/pgsql/9.4/data/pg_hba.conf
service postgresql-9.4 restart

# 測試awx用戶連接，輸入密碼連接，并創建數據庫
psql -U awx -d postgres -h 127.0.0.1
create database awx;
\q
