shark安装器是啥,安装器其实就是把一个游戏的数据包和游戏软件打包在一起的一个APK。它的作用是可以方便大家快速的同时安装好数据包和游戏本身,节省了大家再去下载数据包的时间,可以让大家尽早体验游戏的快乐! 参考技术A Shark安装器是一款简单的下载管理器,能够在您的电脑上快速安装和卸载应用程序和游戏,方便您的电脑使用。它支持多种操作系统,可以下载免费的应用程序、游戏和媒体文件,以及针对各种应用程序和游戏的更新。 参考技术B Wireshark安装、简单使用、过滤器简介love so much 2022-10-13 原文
1.简介
Wireshark是一款非常著名的网络嗅探器,它的前身是Ethereal。Wireshark是一款免费的软件,只需要从官网下根据不同的系统(window,linux等)下载其对应的安装文件即可。
2.安装
window下安装Wireshark,只需要猛戳"next"即可,并且当出现是否需要安装winPcap时,需要点击确认(如果你的电脑之前已经安装有winPcap,建议还是安装Wireshark自带的winPcap,防止出现不兼容的情况)。
linux获取源代码包(或者使用apt-get,rpm等),然后解压缩,使用root权限执行"./configure",然后安装一般方法安装即可。
3.抓包
打开Wireshark,选择Capture,然后选择Interface,选择你需要监听的网卡(如下图所示)

然后单击start,Wireshark就会开始抓包,如果你想停止的话,选择Capture下的stop就行了,得到如下结果。
4.过滤器分类
使用3中的步骤抓到的包很多,不便于分析,这时候就要用到过滤器了。Wireshark主要提供一下两种过滤器:
1.捕获过滤器,当进行数据包捕获时,只有那些满足给定的包含/排除规则的数据包才会被捕获。
2.显示过滤器,当已经捕获到一个数据包集合时,根据指定的规则显示某些数据包,隐藏其他数据包。
5.捕获过滤器
点击Capture->Interface->Option,在"Capture Flter"右边填入过滤表达式,然后点击start即可,如下图所示。

过滤表达式使用的是BPF(Berkeley Packet Filter)语法,引文大多数网络嗅探器都依赖于BPF的libpcap/winpcap库。BPF语法中一个过滤表达式包含多个原语,这些原语通过操作符(与 &&,或 ||,非 !)来进行连接,组成更为高级的表达式。每个原语包含一个或者多个限定词,然后跟一个名字或者数字。典型的BPF限定词如下,
Type 指出名字或者数字所代表的意义 host、net、port
Dir 指明传输方向是前往还是来自名字或数字 src、dst
Proto 限定要匹配的协议 ether、ip、tcp、 参考技术C 这是一套专用于windows 上面的解码包(xp/2003系统也适用),由外国网友制作,如同其他的解码包一样,你无需安装其他的codec或者filter,这个解码包囊括几乎所有常用支持格式的解码。 参考技术D 开门见山。shark是机器学习库。所以其实shark安装的核心就是install模块, 只要我们能把它成功执行, 那么一切顺利, 如果不能直接安装, 才去考虑曲线救国. 在其余项目中使用shark库打开。
60分钟内从零起步驾驭Hive实战学习笔记
本博文的主要内容是:
1. Hive本质解析
2. Hive安装实战
3. 使用Hive操作搜索引擎数据实战
SparkSQL前身是Shark,Shark强烈依赖于Hive。Spark原来没有做SQL多维度数据查询工具,后来开发了Shark,Shark依赖于Hive的解释引擎,部分在Spark中运行,还有一部分在Hadoop中运行。所以讲SparkSQL必须讲Hive。
1. Hive本质解析
1. Hive是分布式数据仓库,同时又是查询引擎,所以SparkSQL取代的只是Hive的查询引擎,在企业实际生产环境下,Hive+SparkSQL是目前最为经典的数据分析组合。
2. Hive本身就是一个简单单机版本的软件,主要负责:
a) 把HQL翻译成Mapper(s)-Reducer-Mapper(s)的代码,并且可能产生很多MapReduce的Job。
b) 把生成的MapReduce代码及相关资源打包成jar并发布到Hadoop集群中运行(这一切都是自动的)
3.Hive本身的架构如下所示:
可以通过CLI(命令终端)、JDBC/ODBC、Web GUI访问Hive。
JavaEE或.net程序可以通过Hive处理,再把处理的结果展示给用户。
也可以直接通过Web页面操作Hive。
※ Hive本身只是一个单机版本的的软件,怎么访问HDFS的呢?
=> 在Hive用Table的方式插入数据、检索数据等,这就需要知道数据放在HDFS的什么地方以及什么地方属于什么数据,Metastore就是保存这些元数据信息的。Hive通过访问元数据信息再去访问HDFS上的数据。
可以看出HDFS不是一个真实的文件系统,是虚拟的,是逻辑上的,HDFS只是一套软件而已,它是管理不同机器上的数据的,所以需要NameNode去管理元数据。DataNode去管理数据。
Hive通过Metastore和NameNode打交道。
2、Hive安装和配置实战
由于,我这里,Spark的版本是1.5.2。
Spark1.5.2中SparkSQL可以指定具体的Hive的版本。
1. 从apache官网下载hive-1.2.1
https://mirrors.tuna.tsinghua.edu.cn/apache/hive/
2、apache-hive-1.2.1-bin.tar.gz的上传
3、现在,新建/usr/loca/下的hive目录
root@SparkSingleNode:/usr/local# pwd
/usr/local
root@SparkSingleNode:/usr/local# ls
bin etc games hadoop include jdk lib man sbin scala share spark src
root@SparkSingleNode:/usr/local# mkdir -p /usr/local/hive
root@SparkSingleNode:/usr/local# cd hive
root@SparkSingleNode:/usr/local/hive# ls
root@SparkSingleNode:/usr/local/hive#
4、将下载的hive文件移到刚刚创建的/usr/local/hive下
root@SparkSingleNode:/usr/local/hive# ls
root@SparkSingleNode:/usr/local/hive# sudo cp /home/spark/Downloads/Spark_Cluster_Software/apache-hive-1.2.1-bin.tar.gz /usr/local/hive/
root@SparkSingleNode:/usr/local/hive# ls
apache-hive-1.2.1-bin.tar.gz
root@SparkSingleNode:/usr/local/hive#
最好用cp,不要轻易要mv
5、解压hive文件
root@SparkSingleNode:/usr/local/hive# ls
apache-hive-1.2.1-bin.tar.gz
root@SparkSingleNode:/usr/local/hive# tar -zxvf apache-hive-1.2.1-bin.tar.gz
6、删除解压包,留下解压完成的文件目录,并修改权限(这是最重要的!!!),其中,还重命名
root@SparkSingleNode:/usr/local/hive# ls
apache-hive-1.2.1-bin apache-hive-1.2.1-bin.tar.gz
root@SparkSingleNode:/usr/local/hive# rm -rf apache-hive-1.2.1-bin.tar.gz
root@SparkSingleNode:/usr/local/hive# ls
apache-hive-1.2.1-bin
root@SparkSingleNode:/usr/local/hive# ll
total 12
drwxr-xr-x 3 root root 4096 10月 9 17:39 ./
drwxr-xr-x 15 root root 4096 10月 9 17:35 ../
drwxr-xr-x 8 root root 4096 10月 9 17:38 apache-hive-1.2.1-bin/
root@SparkSingleNode:/usr/local/hive# mv apache-hive-1.2.1-bin/ apache-hive-1.2.1
root@SparkSingleNode:/usr/local/hive# ll
total 12
drwxr-xr-x 3 root root 4096 10月 9 17:40 ./
drwxr-xr-x 15 root root 4096 10月 9 17:35 ../
drwxr-xr-x 8 root root 4096 10月 9 17:38 apache-hive-1.2.1/
root@SparkSingleNode:/usr/local/hive# chown -R spark:spark apache-hive-1.2.1/
root@SparkSingleNode:/usr/local/hive# ll
total 12
drwxr-xr-x 3 root root 4096 10月 9 17:40 ./
drwxr-xr-x 15 root root 4096 10月 9 17:35 ../
drwxr-xr-x 8 spark spark 4096 10月 9 17:38 apache-hive-1.2.1/
root@SparkSingleNode:/usr/local/hive#
7、修改环境变量
vim ~./bash_profile 或 vim /etc/profile
配置在这个文件~/.bash_profile,或者也可以,配置在那个全局的文件里,也可以哟。/etc/profile。
这里,我vim /etc/profile
#hive
export HIVE_HOME=/usr/local/hive/apache-hive-1.2.1
export PATH=$PATH:$HIVE_HOME/bin
export HIVE_CONF_DIR=/usr/local/hive/apache-hive-1.2.1/conf
root@SparkSingleNode:/usr/local/hive# vim /etc/profile
root@SparkSingleNode:/usr/local/hive# source /etc/profile
8、配置hive
8.1 配置hive-env.sh文件
cp hive-env.sh.template hive-env.sh
spark@SparkSingleNode:/usr/local/hive/apache-hive-1.2.1/conf$ ls
beeline-log4j.properties.template hive-default.xml.template hive-env.sh.template hive-exec-log4j.properties.template hive-log4j.properties.template ivysettings.xml
spark@SparkSingleNode:/usr/local/hive/apache-hive-1.2.1/conf$ cp hive-env.sh.template hive-env.sh
spark@SparkSingleNode:/usr/local/hive/apache-hive-1.2.1/conf$ ls
beeline-log4j.properties.template hive-default.xml.template hive-env.sh hive-env.sh.template hive-exec-log4j.properties.template hive-log4j.properties.template ivysettings.xml
spark@SparkSingleNode:/usr/local/hive/apache-hive-1.2.1/conf$ rm hive-env.sh.template
spark@SparkSingleNode:/usr/local/hive/apache-hive-1.2.1/conf$ ls
beeline-log4j.properties.template hive-default.xml.template hive-env.sh hive-exec-log4j.properties.template hive-log4j.properties.template ivysettings.xml
spark@SparkSingleNode:/usr/local/hive/apache-hive-1.2.1/conf$ vim hive-env.sh
export HIVE_HOME=/usr/local/hive/apache-hive-1.2.1
export PATH=$PATH:$HIVE_HOME/bin
export HIVE_CONF_DIR=/usr/local/hive/apache-hive-1.2.1/conf
8.2 配置hive-env.sh文件
spark@SparkSingleNode:/usr/local/hive/apache-hive-1.2.1/conf$ ls
beeline-log4j.properties.template hive-default.xml.template hive-env.sh hive-exec-log4j.properties.template hive-log4j.properties.template ivysettings.xml
spark@SparkSingleNode:/usr/local/hive/apache-hive-1.2.1/conf$ cp hive-default.xml.template hive-site.xml
spark@SparkSingleNode:/usr/local/hive/apache-hive-1.2.1/conf$ ls
beeline-log4j.properties.template hive-default.xml.template hive-env.sh hive-exec-log4j.properties.template hive-log4j.properties.template hive-site.xml ivysettings.xml
spark@SparkSingleNode:/usr/local/hive/apache-hive-1.2.1/conf$ rm hive-default.xml.template
spark@SparkSingleNode:/usr/local/hive/apache-hive-1.2.1/conf$ ls
beeline-log4j.properties.template hive-env.sh hive-exec-log4j.properties.template hive-log4j.properties.template hive-site.xml ivysettings.xml
spark@SparkSingleNode:/usr/local/hive/apache-hive-1.2.1/conf$ vim hive-site.xml
Hive默认情况下放元数据的数据库是Derby,遗憾的是Derby是单用户,所以在生产环境下一般会采用支持多用户的数据库来进行MetaStore,且进行Master-Slaves主从读写分离和备份(一般Master节点负责写数据,Slaves节点负责读数据)。最常用的是MySQL。
于是,删除它,在本地上写好,上传即可。

可能由于root的权限不够,可以进行如下操作
1) 以root进入mysql
root@SparkSingleNode:/usr/local/hive/apache-hive-1.2.1# mysql -uroot -prootroot
root@SparkSingleNode:/usr/local/hive/apache-hive-1.2.1# mysql -uroot -prootroot

Hive中的DataBase和表其实就是HDFS上的目录和简单的文本文件。简单的文本文件中有几列数据,每列数据的类型无法直接从文本文件中得知。但当数据放入Hive中,Hive就把元数据放入Mysql中了,这样就可以基于数据的表进行查询了。

9. MYSQL的安装和配置 (路径,没要求)
root用户下执行yum -y install mysql-server(CentOS版本)或apt-get install mysql-server(Ubuntu版本) 即可自动安装
9.1 在线安装mysql数据库
root@SparkSingleNode:/usr/local/hive/apache-hive-1.2.1# pwd
/usr/local/hive/apache-hive-1.2.1
root@SparkSingleNode:/usr/local/hive/apache-hive-1.2.1# yum -y install mysql-server
The program \'yum\' is currently not installed. You can install it by typing:
apt-get install yum
root@SparkSingleNode:/usr/local/hive/apache-hive-1.2.1# apt-get install mysql-server

9.2 查看mysql服务状态,若是关闭,则启动mysql服务。
root@SparkSingleNode:/usr/local/hive/apache-hive-1.2.1# service mysql status
mysql start/running, process 9868
root@SparkSingleNode:/usr/local/hive/apache-hive-1.2.1# sudo /etc/init.d/mysql start

root@SparkSingleNode:/usr/local/hive/apache-hive-1.2.1#
9.3 设置MySQL的root用户设置密码,这一步,就不需要做了,在CentOS版本里,需要做。在Ubuntu版本,在安装时,就已经设置了。
9.4 以root用户,登录mysql看看。
root@SparkSingleNode:/usr/local/hive/apache-hive-1.2.1# mysql -u root -p
Enter password: (rootroot)

更多,可以,参考
1 复习ha相关 + weekend110的hive的元数据库mysql方式安装配置
由此,说明mysql数据库,安装成功!
5. Hive的表有两种基本类型:一种是内部表(这种表数据属于Hive本身,即如果原来的数据在HDFS的其他地方,此时数据会通过HDFS移动到Hive所在目录,如果删除Hive中的该表的话数据和元数据均会被删除),一种是外部表(这种表数据不属于Hive数据仓库,元数据中会表达具体数据在哪里,使用时和内部表的使用一样,只是如果通过Hive去删除的话,删除的只是元数据,并没有删除数据本身)
三. 使用Hive分析搜索数据
启动HDFS/Yarn。注意如果要使用Hive进行查询就需要启动Yarn。
启动Hive。
通过show databases;可以查看数据库。默认database只有default。
creeate database hive;
use hive;
create table person(name String,age int);
insert into person values(‘richard’,’34’);
select * from person;即可查询。
