openstack安装问题

Error

Fix:
Adjust the admin token to be the same as your script and your /etc/keystone/keystone.conf

driver = keystone.catalog.backends.templated.TemplatedCatalog
template_file = /etc/keystone/default_catalog.templates

Make sure it looks like this: connection = mysql://keystone:openstack@localhost:3306/keystone

Not that is for glance.registry :/ mysql_connection = mysql://keystone:openstack@localhost:3306/keystone

在装openstack时，出错的可能只是一个服务模块，比如mysql，keystone，glance，nova等等，我们就需要把相应的模块卸载掉，不用重装整个系统了，这可以节省我们很多的时间，但很多人有不知道完全卸载这些模块的命令，往往保留了以前装的错误的配置文件，这就需要我们把所有的配置文件都卸载干净。

现在我给大家提供一些完全卸载的命令，我们可以写成脚本语言，可以很方便的执行：
#!/usr/bin/env bash
#删除glance
apt-get remove -y glance glance-api glance-client glance-common glance-registry python-glance
#删除nova
apt-get remove -y nova-api nova-cert nova-common nova-compute nova-compute-kvm nova-doc nova-network nova-objectstore nova-scheduler nova-volume python-nova python-novaclient nova-consoleauth python-novnc novnc
删除dashboard
apt-get remove -y libapache2-mod-wsgi openstack-dashboard
#删除mysql数据库
apt-get remove -y mysql-server python-mysqldb
#删除keystone
apt-get remove -y keystone python-keystone python-keystoneclient

dpkg -l |grep keystone|awk '{print $2}'|xargs dpkg -P
dpkg -l |grep glance|awk '{print $2}'|xargs dpkg -P
dpkg -l |grep nova|awk '{print $2}'|xargs dpkg -P
dpkg -l |grep mysql|awk '{print $2}'|xargs dpkg -P
dpkg -l |grep libapache2-mod-wsgi|awk '{print $2}'|xargs dpkg -P

## 删除掉mysql里相应的数据库
MYSQL_PASSWD=${MYSQL_PASSWD:-"cloud1234"}
mysql -uroot -p$MYSQL_PASSWD -e "DROP DATABASE IF EXISTS nova;"
mysql -uroot -p$MYSQL_PASSWD -e "DROP DATABASE IF EXISTS glance;"
mysql -uroot -p$MYSQL_PASSWD -e "DROP DATABASE IF EXISTS keystone;"

Hi Connect to mysql and do the following: drop database keystone; create database keystone; This will re create the keystone DB to have a fresh start. Finally, execute keystone-manage db_sync and re-execute the scripts.

ou may also use the restart|star|sto(8)p utility, e.g.类错误

提示类似于如下：

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service squid start

Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the start(8) utility, e.g. start squid

以下方式进行：

sudo restart squid #重启

sudo start squid #启动
