Ubuntu server 14.0464位上編譯Hadoop 2.6.4(純鍵盤模式)

日期：2017/3/1 11:44:14 编辑：關於Linux

注意：以下都是在root用戶下完成的，不喜歡撸（打）sudo這個單詞。

Step1 配置JDK環境

自動化安裝jdk
因為安裝的ubuntu server 14.04 的初始版本是沒有JDK的：

root@master:~# javac
The program 'javac' can be found in the following packages:
 * default-jdk
 * ecj
 * gcj-4.8-jdk
 * openjdk-7-jdk
 * gcj-4.6-jdk
 * openjdk-6-jdk
Try: apt-get install 
root@master:~#

所以需要我們安裝包安裝jdk也行，自動安裝也行。安裝包的話，見我的參考文檔，自動的話，我們開始吧。
輸入命令：

root@master:~# apt-get install openjdk-7-jdk

安裝的時間比較長，需要等待一段時間。

配置JDK的環境變量
Jdk安裝完成後，我們需要配置一下環境變量，至於這個java安裝到哪了，我們需要查找一下，在這裡查找jre*即可，因為jre一般都放在java目錄下的：

root@master:~# find / -name  'jre*'
/usr/lib/jvm/java-7-openjdk-amd64/jre
root@master:~#

配置java的環境變量：

root@master:~# vi /etc/profile
將這些輸入到最後：
export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH

重新啟動機器，查看java的版本信息，如果出現如下信息，則安裝成功：

root@master:~# java -version
java version "1.7.0_101"
OpenJDK Runtime Environment (IcedTea 2.6.6) (7u101-2.6.6-0ubuntu0.14.04.1)
OpenJDK 64-Bit Server VM (build 24.95-b01, mixed mode)
root@master:~#

安裝Maven編譯器
Maven：
maven是一個項目構建和管理的工具，提供了幫助管理構建、文檔、報告、依賴、scms、發布、分發的方法。可以方便的編譯代碼、進行依賴管理、管理二進制庫等等。
maven的好處在於可以將項目過程規范化、自動化、高效化以及強大的可擴展性
利用maven自身及其插件還可以獲得代碼檢查報告、單元測試覆蓋率、實現持續集成等等。
在這裡是自動化安裝，當然是直接命令啦：

root@master:~# apt-get install maven

經過漫長的等待，如果輸入查看版本信息，輸出版本信息則證明安裝成功：

root@master:~# mvn --version
Apache Maven 3.0.5
Maven home: /usr/share/maven
Java version: 1.7.0_101, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-7-openjdk-amd64/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.13.0-24-generic", arch: "amd64", family: "unix"
root@master:~#

安裝openssh
Openssh：
OpenSSH 是 SSH （Secure SHell）協議的免費開源實現。SSH協議族可以用來進行遠程控制，或在計算機之間傳送文件。而實現此功能的傳統方式，如telnet(終端仿真協議)、 rcp ftp、 rlogin、rsh都是極為不安全的，並且會使用明文傳送密碼。OpenSSH提供了服務端後台程序和客戶端工具，用來加密遠程控件和文件傳輸過程中的數據，並由此來代替原來的類似服務。
OpenSSH是使用SSH透過計算機網絡加密通訊的實現。它是取代由SSH Communications Security所提供的商用版本的開放源代碼方案。目前OpenSSH是OpenBSD的子計劃。
OpenSSH常常被誤認以為與OpenSSL有關聯，但實際上這兩個計劃的有不同的目的，不同的發展團隊，名稱相近只是因為兩者有同樣的軟件發展目標──提供開放源代碼的加密通訊軟件。
現在上命令：

apt-get install openssh-server openssh-client

又是一段漫長的等待啊：

安裝protobuf-compiler
Protobuf：
Protocol Buffers (ProtocolBuffer/ protobuf )是Google公司開發的一種數據描述語言，類似於XML能夠將結構化數據序列化，可用於數據存儲、通信協議等方面。現階段支持C++、JAVA、Python等三種編程語言。

安裝依賴庫
這些庫啊包啊基本都會在編譯過程中用到，缺少的話會影響編譯，看到error了再找solution非常麻煩，提前裝好一勞永逸。

apt-get install g++ autoconf automake libtool cmake zlib1g-dev pkg-config libssl-dev

安裝findbugs
FindBugs：
是一個靜態分析工具，它檢查類或者 JAR 文件，將字節碼與一組缺陷模式進行對比以發現可能的問題。有了靜態分析工具，就可以在不實際運行程序的情況對軟件進行分析。不是通過分析類文件的形式或結構來確定程序的意圖，而是通常使用 Visitor 模式（請參閱參考資料）。圖 1 顯示了分析一個匿名項目的結果（為防止可怕的犯罪，這裡不給出它的名字）：
在FindBugs的GUI中，需要先選擇待掃描的.class文件(FindBugs其實就是對編譯後的class進行掃描，藉以發現一些隱藏的bug。)。如果你擁有這些.class檔對應的源文件，可把這些.java文件再選上，這樣便可以從稍後得出的報告中快捷的定位到出問題的代碼上面。此外，還可以選上工程所使用的library，這樣似乎可以幫助FindBugs做一些高階的檢查，藉以發現一些更深層的bug。
選定了以上各項後，便可以開始檢測了。檢測的過程可能會花好幾分鐘，具體視工程的規模而定。檢測完畢可生成一份詳細的報告，藉由這份報告，可以發現許多代碼中間潛在的bug。比較典型的，如引用了空指針(null pointer dereference), 特定的資源(db connection)未關閉，等等。如果用人工檢查的方式，這些bug可能很難才會被發現，或許永遠也無法發現，直到運行時發作…當除掉了這些典型的 (classic) bug後，可以確信的是，我們的系統穩定度將會上一個新的台階。
以目前遇到的狀況來看，FindBugs可以有兩種使用時機。
輸入命令（自我感覺這個用處不大，但是為了防止後面出現問題，還是多此一舉吧）：

root@master:~# apt-get install findbugs

開始編譯
給大家道個歉，因為我說過，是純手打編譯的，但是這個命令是我拷貝的，因為太長了，地址怕搞錯，所以在現實工作環境中，沒有拷貝環境的話，還是請大家手打吧，敲得時候認真點。首先，我們需要在網上下載一個Hadoop版本，我用的是Hadoop 2.6.4版本的，下載地址：

root@master:~# wget http://mirrors.tuna.tsinghua.edu.cn/apache/hadoop/common/hadoop-2.6.4/hadoop-2.6.4-src.tar.gz
--2016-07-05 18:24:46--  http://mirrors.tuna.tsinghua.edu.cn/apache/hadoop/common/hadoop-2.6.4/hadoop-2.6.4-src.tar.gz

root@master:~# ls
hadoop-2.6.4-src.tar.gz

解壓文件夾到當前目錄：

root@master:~# tar -zxvf hadoop-2.6.4-src.tar.gz
root@master:~# ls
hadoop-2.6.4-src  hadoop-2.6.4-src.tar.gz
進入到Hadoop-2.6.4-src文件中：
root@master:~#cd /root/xyj/hadoop-2.6.4-src

激動人心的時刻到了，終於到了編譯時刻了：

root@master:~/hadoop-2.6.4-src# mvn clean package -Pdist,native -DskipTests -Dtar

OK，在這裡我們需要等待漫長的時間。期間保證網速達到要求，不斷電，一般都是一兩個小時即可完成編譯，如果設備和網絡的原因，那就需要時間大於2小時不等了。
Hadoop下載地址怎麼找？
【首先來到官網：http://hadoop.apache.org/，找到Getting Started，點擊Download，進入到Hadoop的release版本下載地址：http://hadoop.apache.org/releases.html，我們會發現很多版本的下載地址，在這裡選擇一個你認為順眼的一個，我選擇是Hadoop 2.6.4，點擊Tarball下對應的source，進入到：http://www.apache.org/dyn/closer.cgi/hadoop/common/hadoop-2.6.4/hadoop-2.6.4-src.tar.gz，我們會發現一個http地址，將這個地址就是我們的下載地址。把地址放在wget後面即可！】

問題解決
程序員最怕就是bug了，改不出bug，就是我們的噩夢，Error同樣恐怖啊！！！但是我們還是要面對問題的，遇到問題要慢慢來解決，隨話說，改bug不只有今天的苟且，還有明天和後天，我就不信改不出來，有時候你會發現，突然他就那麼好了，雖然不知道什麼問題。

去吃了個飯，發現編譯出錯了，好了，開始解決吧！在網上搜錯誤怎麼解決，沒找到，還是自己看日志吧，日志大致意思是tomcat服務器有問題，所以我感覺自己安裝的新系統沒有裝tomcat服務器，所以輸入命令：

root@master:~/xyj/hadoop-2.6.4-src# apt-get install tomcat7
重新編譯：
root@master:~/xyj/hadoop-2.6.4-src# mvn clean package -Pdist,native -DskipTests -Dtar

漫長的等待，以為上面沒有解決問題呢，但是我發現，編譯剛才錯的那一塊竟然過去了，過去了就過去了吧，這也是解決問題的方法之一，總比沒解決問題吧，唯一的不足之處就是真正不知道錯哪了，只是憑感覺走的，正好誤打誤撞過去了，希望不是吧！

真是頭疼，好好搜搜問題解決方法吧！告訴大家一個調試詳細錯誤的命令，在原有命令上添加一個 –X參數，我們就可以看到詳細的編譯過程了：

root@master:~/xyj/hadoop-2.6.4-src# mvn clean package -Pdist,native -DskipTests -Dtar -X

這個問題，我找了很多網站，也是找不到結果，看了很多的帖子和問題，歸根一點就是我的網速和鏡像站的問題，可能是網速有時候太慢，網絡不能訪問到外網的原因吧！所以索性下載了一個lantern，翻牆用的（也可能是網絡原因，網絡在某個時刻下載大文件卡住了，然後編譯執行到這一步，沒有這個文件，或者是文件下載不全，都會引起編譯失敗，所以不一定是翻牆的原因，可能是網絡在編譯時尋找路由或者是網站的時候，沒有找到，第二次就找到了，這怎麼感覺就是拼人品啊！）。
接下來就教大家安裝lantern吧！

好了，這個安裝完，我們繼續吧！我感覺只是給自己一個心理安慰，這個重新編譯是否成功，就看人品了！還好，編譯通過了，感謝人品啊！

上圖顯示了編譯的所有文件，他們都是分布一個個編譯，當失敗到哪，就會把成功的和失敗的，跳過失敗之後的那些項目顯示出來，這個忘了截圖，好吧！你們自己編譯會看到的。
編譯好之後，我們需要找到我們編譯好的包，路徑是：

其中有一個hadoop-2.6.4.tar.gz的包就是的，還有解壓好的hadoop-2.6.4文件夾。

那個hadoop-2.6.4.tar.gz中的文件解壓後和這個一樣。一會用的時候拷貝那個hadoop-2.6.4.tar.gz的文件，人嘛，就喜歡用原裝的，嘻嘻。。。

小結
至此，Hadoop-2.6.4版本的編譯好了。給大家的承諾是全鍵盤操作，不過我自己就作弊了，給大家拷貝了那麼多流程，還有一個網址，懶得打，對於初學者，還是建議大家一個字一個字敲下去，對於成熟的開發人員，這個你們自便。
對於裡面出現的一些問題，以及我沒遇到的問題，可能你們在安裝的時候，會出現問題，請大家積極去解決它，一天不行兩天，兩天不行三天，三天不行放棄吧！不必浪費這麼多時間了，再重新搞，或者是把問題消滅掉。
編譯的過程大致是，mvn這個軟件將我們編譯Hadoop的文件全部下載到本地，然後慢慢的一個一個編譯，直到編譯成功。如果中途失敗，則程序停止，只有將問題解決了，才能重新運行程序編譯成功。
對於編譯過程中，遇到的問題，大多都是網絡的原因，還有就是鏡像站的原因，我們下載不了外面的資源，只能認倒霉重新讓網絡找一個好的地址，這樣的話，導致後果就是我們要重新編譯，重新編譯有時也解決不了一些問題，只有大家，慢慢的憑經驗吧！
