Ubuntu下重新安装 Ansible AWX

一个同事误删了/etc/awx/settings.py 造成AWX 不能正常使用。

当时的想法就是重新安装AWX。现在想想，如果在首次安装后没有对settings.py 进行过修改，可以直接从安装包里恢复就行。不过要根据awx-setup-1.3.1/group_vars/all 里的值对awx-setup-1.3.1/roles/awx_install/templates/settings.py.j2 里的变量进行初始化。

# Uninstall the current one

apt-get remove awx

# Install AWX

awx-setup-1.3.1# ./setup.sh

不过遇到了下面的错误：

尝试过在postgre 数据库中修改user ‘awx’ 的密码，甚至卸载整个postgre 数据库，可是问题依旧。

其实user awx 是在安装过程中创建的, 改数据看里密码肯定不起作用。

其实这里的关键在于要把user awx 从系统里删除。
