部署
设置主机信息
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

安装ansible
./setup.sh
在TASK [awx_install : Migrate the Tower database schema (may take awhile when upgrading).] ***
这一步会出现错误,提示信息是数据库连接不上
启动postgresql
service postgresql-9.4 initdb
service postgresql-9.4 start
创建用户
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
测试awx用户连接,输入密码连接,并创建数据库
psql -U awx -d postgres -h 127.0.0.1
create database awx;
\q
再次./setup.sh
进行安装tower

下载反编译工具: http://sourceforge.net/projects/easypythondecompiler/
反编译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
反编译后的文件为task_engine.pyc_dis,文件重命名为task_engine.py
修改内容
89
行和186
行代码
available_instances = int(self.attributes[‘instance_count‘]) 为available_instances = 10000
Paste_Image.png
Paste_Image.png
247
行代码,把相应的功能由False
改为True(这步未实施)
Paste_Image.png
删除task_engine.pyc task_engine.pyo 重启tower
rm -f /var/lib/awx/venv/tower/lib/python2.7/site-packages/awx/main/task_engine.py*
ansible-tower-service restart
查看license信息

安装时遇到的错误
fatal: [localhost]: FAILED! => {"changed": false, "failed": true, "msg": "This machine does not have sufficient RAM to run Ansible Tower."}
解决:机器内存不足,增加内存
fatal: [localhost]: FAILED! => {"changed": false, "failed": true, "msg": "no service or tool found for: supervisord"}
解决:yum -y install supervisor
出现Is the server running on host \"localhost\" (127.0.0.1) and accepting\n\tTCP/IP connections on port 5432?
是postgresql服务没启动
service postgresql-9.4 initdb
service postgresql-9.4 start
# 创建用户
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
# 测试awx用户连接,输入密码连接,并创建数据库
psql -U awx -d postgres -h 127.0.0.1
create database awx;
\q
