centos one key，centos镜像
其实centos one key的问题并不复杂，但是又很多的朋友都不太了解centos镜像，因此呢，今天小编就来为大家分享centos one key的一些知识，希望可以帮助到大家，下面我们一起来看看这个问题的分析吧！
干货| 手把手教你搭建一套OpenStack云平台
今天我们为一位朋友搭建一套OpenStack云平台。
我们使用Kolla部署stein版本的OpenStack云平台。
kolla是用于自动化部署OpenStack的一个项目，它基于docker和ansible来实现；docker主要负责镜像制作、容器管理。而ansible主要负责环境的部署和管理。
由于我个人笔记本性能有限，因此本次实验采用all-in-one模式部署，即所有服务都部署在一台主机上。其实只要all-in-one模式熟练部署，多节点部署上手很快的。
接下来，让我们一步步进行OpenStack云平台的搭建：
1）主机网卡配置
2）关闭防火墙、selinux及libvirtd服务
3）安装epel源
4）CentOS部分常用软件安装
5）配置主机名及hosts文件
6）同步时间
7）配置 pip镜像源，方便快速下载python库
1）安装基础包
2）升级pip版本，不后期安装会有报警
3）安装docker-ce
4）指定docker镜像加速器
5）设置docker volume卷挂载方式
6）重启使配置生效
1）安装ansible
2）下载kolla及kolla-ansible代码
3）手动安装kolla-ansible
4）安装kolla-ansible需要依赖包
5）安装kolla需要依赖包
6）拷贝配置文件
配置文件解释：
6）生成随机密码
使用kolla提供的密码生成工具自动生成OpenStack各服务的密码，如果密码不填充，后面的部署环境检查时不会通过的。
7）修改随机密码文件
8）修改globals.yml配置文件
1）生成SSH Key，并授信本节点
2）配置单节点all-in-one配置文件
3）带有kolla的引导服务器部署依赖关系
执行结果如下：
4）对主机执行预部署检查
执行结果如下：
5）拉取OpenStack镜像
我们看下它在执行什么
正在下载OpenStack镜像，等等哦
聪明的小伙伴会趁它在自动部署过程中，思考下当命令敲下去以后它都做了哪些操作
6）执行OpenStack部署
7）验证部署
执行结果如下，则说明您的OpenStack环境已部署成功！Congratulations!
我们也生成了admin用户的凭证，即/etc/kolla/admin-openrc.sh文件
我们看下该凭证：
在浏览器中输入：192.168.1.251
用户名：admin
密码：123123
登录密码我们在passwords.yml中指定为123123,在实际生产环境中可不能设置这么简单哦。
到此已完成OpenStack云平台的部署，明天我们再来讨论下OpenStack云平台基本使用方法及利用OpenStack客户端命令创建一台测试云主机。
别看我搭建这么顺利呀，真到你部署了，可能会满屏报错哦。一定要细心，一不留神就会出现如下情况：
linux虚拟机怎么安装vmware tools
Linux VMware Tools安装步骤简易版
Linux VMware Tools安装估计有点困难，我也在网上看了好多版本的Linux安装VMware Tools，方法都一样。但是自己在安装过程中，还是遇到了点问题。但是最终还是搞定。我运行的是VMware workstation 8.0.4, OS: CentOS 6.0
1.在CD-ROM虚拟光驱中选择使用ISO镜像，找到VMWARE TOOLS安装文件，如C:\program\VMware\VMware Workstation\Programs\linux.iso
当然这个ISO是你安装VMware workstation的目录下的Linux.iso，不是你的Linux OS镜像文件。VMware Tools一般都在这个文件里。
2.以管理员身份进入Linux，root账号
3.退出到windows,在虚拟机菜单栏中点击虚拟机->安装 VMWARE TOOLS子菜单,会弹出对话框，点击"确认"安装
4.挂载光驱：Mount-t iso9660/dev/cdrom/mnt
加载CDROM设备，这是如果进入/mnt目录下，你会发现一个文件：
VMwareTools-8.8.4-743747.tar.gz
这个就死VMware Tools的Linux软件包，也是我们刚才使用的WinISO打开的Liunx.ISO
有的虚拟机上估计执行mount/dev/cdrom/mnt/cdrom
如果提示如下错误，挂载点不存在。，[root@localhost/]#mount/dev/cdrom/mnt/cdrom
mount: mount point/mnt/cdrom dose not exist
请直接执行此命令：
mount/dev/cdrom/opt
cd/opt
或者应该可以使用自动挂载，直接进入
cd/misc/cd
5. copy此文件到临时文件夹
cp/mnt/mVMwareTools-8.8.4-743747.tar.gz/tmp
6.卸载CDROM，执行 umount/dev/cdrom
7.进入tmp文件目录并解压此文件包
cd/tmp
tar zxf vmware-linux-tools.tar.gz
解压默认到vmware-tools-distrib目录下：此时你可以使用ls-ll查看文件夹下的文件
8.进入vmware-tools-distrib，安装vmware tools.
./vmware-install.pl执行安装，
安装过程中他会一步一步的有问题回应，此过程中，你遇到后面显示[yes],[no],[yes][no]的直接输入yes，然后回车。其他的问题不管[]里面是什么，直接回车就好了，不要输入。
9.大约5分钟左右安装完成。执行init 6重启ok。

You must restart your X session before any mouse or graphics changes take
effect.
You can now run VMware Tools by invoking the following command:
"/usr/bin/vmware-toolbox" during an X server session.
To enable advanced X features(e.g., guest resolution fit, drag and drop, and
file and text copy/paste), you will need to do one(or more) of the following:
1. Manually start/usr/bin/vmware-user
2. Log out and log back into your desktop session; and,
3. Restart your X session.
To use the vmxnet driver, restart networking using the following commands:
/etc/init.d/network stop
rmmod pcnet32
rmmod vmxnet
modprobe vmxnet
/etc/init.d/network start

Centos6.5中如何用sqlite3命令打开’.db’后缀的数据库执行sql
1.简单sql语句使用：
在任意目录下新建一个数据库,比如student。
命令: sqlite3 student.db
出现如下提示：
输入sql语句create table user(username text primary key, password text);建一张user表
输入sql语句insert into user values("baoli","123");插入一条数据。
输入sql语句select* from user;可以查看user表.
输入sql语句delete from user where username=‘baoli‘;删除指定的一个记录。
注：输入sql命令是记得结尾的‘;‘号。
2. SQLite支持如下5种数据类型
1.NULL：空值。
2.INTEGER：带符号的整型，具体取决有存入数字的范围大小。
3.REAL：浮点数字，存储为8-byte IEEE浮点数。
4.TEXT：字符串文本。
5.BLOB：二进制对象。
3.一些常用命令
查看当前数据库的所有数据表：.tables
查看当前所有数据库：.databases
打开或创建一个表：sqlite3 test.db
可视化打开数据库：sqlitebrowser student.db
注：需要：sudo apt-get install sqlitebrowser
