hadoop-2.7.4编译安装

1.protobuf编译安装

[root@hadoop1 ~]# yum install svn autoconf automake libtool cmake ncurses-devel openssl-devel gcc*[root@hadoop1 ~]# tar -zxf protobuf-2.5.0.tar.gz[root@hadoop1 ~]# cd protobuf-2.5.0/[root@hadoop1 protobuf-2.5.0]# ./configure --prefix=/usr/local/protobuf2.5/ ...[root@hadoop1 protobuf-2.5.0]# make && make install[root@hadoop1 protobuf-2.5.0]# tail -2 /etc/profile #配置环境变量export PROTOC_HOME=/usr/local/protobuf2.5/export PATH=.$PATH:$PROTOC_HOME/bin[root@hadoop1 protobuf-2.5.0]# protoc --version #验证libprotoc 2.5.0

2.maven安装

[root@hadoop1 ~]# yum install maven #使用yum安装maven会自动安装jdk和ant[root@hadoop1 ~]# mvn -versionApache Maven 3.0.5 (Red Hat 3.0.5-17)Maven home: /usr/share/mavenJava version: 1.8.0_141, vendor: Oracle CorporationJava home: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.141-1.b16.el7_3.x86_64/jreDefault locale: en_US, platform encoding: UTF-8OS name: "linux", version: "3.10.0-514.el7.x86_64", arch: "amd64", family: "unix"[root@hadoop1 ~]# java -versionopenjdk version "1.8.0_141"OpenJDK Runtime Environment (build 1.8.0_141-b16)OpenJDK 64-Bit Server VM (build 25.141-b16, mixed mode)[root@hadoop1 ~]#

3.编译安装hadoop

[root@hadoop1 ~]# tar -zxf hadoop-2.7.4-src.tar.gz[root@hadoop1 ~]# cd hadoop-2.7.4-src/[root@hadoop1 hadoop-2.7.4-src]# mvn package -Pdist -DskipTests -Dtar #安装过程大约1小时main:     [exec] $ tar cf hadoop-2.7.4.tar hadoop-2.7.4     [exec] $ gzip -f hadoop-2.7.4.tar     [exec]      [exec] Hadoop dist tar available at: /root/hadoop-2.7.4-src/hadoop-dist/target/hadoop-2.7.4.tar.gz     [exec] [INFO] Executed tasks[INFO] [INFO] --- maven-javadoc-plugin:2.8.1:jar (module-javadocs) @ hadoop-dist ---[INFO] Building jar: /root/hadoop-2.7.4-src/hadoop-dist/target/hadoop-dist-2.7.4-javadoc.jar[INFO] ------------------------------------------------------------------------[INFO] Reactor Summary:[INFO] [INFO] Apache Hadoop Main ................................
