安裝maven編譯環境

安裝maven編譯環境

1.默認已經裝好yum並配置好yum源(推薦使用163yum源)
2.安裝JDK
3.安裝相關依賴環境(root用戶登錄)
    yum install -y cmake lzo-devel zlib-devel gcc gcc-c++ autoconf automake libtool ncurses-devel openssl-devel libXtst
4.安裝protobuf(root用戶登錄)
    tar xvf protobuf-2.5.0.tar.gz   //必須是2.5.0
    cd protobuf-2.5.0
    ./configure
    make
    make install
    ldconfig
    
    protoc --version  //驗證是否安裝成功
5.安裝ANT(root用戶登錄)
    tar zxvf apache-ant-1.9.4-bin.tar.gz  //能夠是最新版
    
    修改環境變量
    #ant
    export ANT_HOME=/opt/ant-1.9.6
    export PATH=$PATH:$ANT_HOME/bin
6.安裝maven(root用戶登錄)
    tar zxvf apache-maven-3.3.1-bin.tar.gz  //最好是3版本以上
    
    修改環境變量
    export MAVEN_HOME=/opt/maven-3.3.1
    export MAVEN_OPTS="-Xms256m -Xmx512m"
    export PATH=$PATH:$MAVEN_HOME/bin
    
    修改配置文件  conf/settings.xml
        更改maven資料庫，在<mirrors></mirros>裏添加以下內容：

          <mirror>
                <id>nexus-osc</id>
                <mirrorOf>*</mirrorOf>
            <name>Nexusosc</name>
            <url>http://maven.oschina.net/content/groups/public/</url>
          </mirror>


        在<profiles></profiles>內新添加

            <profile>
                  <id>jdk-1.7</id>
                  <activation>
                    <jdk>1.7</jdk>
                  </activation>
                  <repositories>
                    <repository>
                      <id>nexus</id>
                      <name>local private nexus</name>
                      <url>http://maven.oschina.net/content/groups/public/</url>
                      <releases>
                        <enabled>true</enabled>
                      </releases>
                      <snapshots>
                        <enabled>false</enabled>
                      </snapshots>
                    </repository>
                  </repositories>
                  <pluginRepositories>
                    <pluginRepository>
                      <id>nexus</id>
                      <name>local private nexus</name>
                      <url>http://maven.oschina.net/content/groups/public/</url>
                      <releases>
                        <enabled>true</enabled>
                      </releases>
                      <snapshots>
                        <enabled>false</enabled>
                      </snapshots>
                    </pluginRepository>
                  </pluginRepositories>
            </profile>
7.安裝findbugs(root用戶登錄)
    tar zxvf findbugs-3.0.1.tar.gz
    
    修改環境變量
    #findbugs
    export FINDBUGS_HOME=/opt/findbugs-3.0.1
    export PATH=$PATH:$FINDBUGS_HOME/bin

8.添加jar CLASSPATH(root用戶登錄)
    export CLASSPATH=$CLASSPATH:$ANT_HOME/lib:$MAVEN_HOME/lib:$FINDBUGS_HOME/lib
    
9.編譯hadoop-2.6.0(以非root用戶登錄)
    tar zxvf hadoop-2.6.0-src.tar.gz
    cd hadoop-2.6.0-src
    mvn package -Pdist,native,docs -DskipTests -Dtar -Dmaven.Javadoc.skip=true
    //注意修改相關的hosts文件  有可能有些包被牆了。  有沒被牆的驗證方法就是可否訪問谷歌

9.常見異常
    1.Exit code: 1 - /home/lpf/devTool/hadoop-2.6.0-src/hadoop-common-project/hadoop-annotations/src/main/java/org/apache/hadoop/classification/interfaceStability.java:27: 錯誤: 意外的結束標記: </ul>
       解決辦法: mvn package -Pdist,native,docs -DskipTests -Dtar -Dmaven.Javadoc.skip=true 以這條命令編譯運行
    2.[ERROR] mvn <goals> -rf :hadoop-common
       解決辦法: 將節點hadoop-annotations的值由provide 改爲compile
                vim ./hadoop-common-project/hadoop-auth/pom.xml
                vim ./hadoop-common-project/hadoop-common/pom.xml 
                    <dependency>
                        <groupId>org.apache.hadoop</groupId>
                        <artifactId>hadoop-annotations</artifactId>
                        <scope>compile</scope>
                    </dependency>
    3.apache-tomcat-6.0.41.tar.gz 下載太卡的問題
       解決辦法：能夠手動下載這個包，而後放到 hadoop-2.6.0-src/hadoop-common-project/hadoop-kms/downloads/ 目錄下
