6,Ubuntu ssh 登录慢问题

Ubuntu 中 ssh 登录非常缓慢，输入用户名后要等好一阵先出现提示输入密码, 这是Ubuntu默认开启了 SSH 的 DNS反解析造成的原因，只要将此选项关闭, 重新启动sshd后反应非常快。

vi /etc/ssh/sshd_config

在最后添加下面一行,关闭 SSH 的 DNS 反解析:

UseDNS no

service ssh restart即可搞定;

7,修改rabbitmq Message broker 用户密码

Functions test Environment or production Environment;

8,OpenStack packages for Ubuntu 相关组件的配置信息存储在sqlite中

 

sqlite3程序通过查找分号来决定一个SQL语句的结束

sqlite3中sql必须要以;结尾,sql语句就是以;判断语句句尾的,但sqlite命令尾部则不用加;

SQLite数据库的框架被保存在一个名叫"sqlite_master"的特殊的表中
