解决方法

查看已安装的postgresql，发现并没有完全安装成功。
rpm -qa|grep postg

postgresql96-9.6.5-1PGDG.rhel7.x86_64
pcp-pmda-postgresql-3.10.6-2.el7.x86_64
postgresql96-libs-9.6.5-1PGDG.rhel7.x86_64

进入pg挂载目录手动安装

cd /var/lib/tower-bundle/pgdg96
rpm -Uvh *.rpm

查看是否安装成功，包含以下四个代表安装成功了。
rpm -qa|grep postg

postgresql96-server-9.6.6-1PGDG.rhel7.x86_64
postgresql96-libs-9.6.6-1PGDG.rhel7.x86_64
pcp-pmda-postgresql-3.10.6-2.el7.x86_64
postgresql96-9.6.6-1PGDG.rhel7.x86_64

由于这个版本的postgresql安装判断有问题，所以手动关闭安装postgresql的脚本。

cd ansible-tower-setup-bundle-3.2.2-1.el7/roles/packages_el/tasks/
vi main.yml
把or 修改为and

- include: install_postgres.yml
  when: "packages_el_install_postgres == true **and** config_dynamic_database == 'internal'"

初始化db
/usr/pgsql-9.6/bin/postgresql96-setup initdb
启动postgresql和自启动

systemct enable  postgresql-9.6
systemctl start postgresql-9.6
systemctl status postgresql-9.6

接着执行
sh setup.sh
