按照这个安装指南：

https://docs.cloudstack.apache.org/projects/cloudstack-installation/en/latest/qig.html

运行安装命令时：

# yum -y install cloudstack-management 

它得到了一个无法findULR 404错误。 是官方档案坏了的原因吗？

• Munin磁盘延迟警报
• 更新PHPMyAdmin的依赖性错误
• 在CentOS 6.6上安装Azure CLI时出错
• 安装在老版本的python下的pip
• 使用iptables阻止默认IP的直接端口80访问？

数据库连接exception。 如何正确设置数据库？ 我只是遵循那个指南，但不知道任何其他的事情。

 # yum -y install mysql-server # service mysqld start # chkconfig mysqld on 

 # yum -y install cloudstack-management # cloudstack-setup-databases cloud:password@localhost --deploy-as=root # cloudstack-setup-management
