1. 安裝JAVA

#yum install java

#java -version
java version "1.7.0_101"
OpenJDK Runtime Environment (rhel-2.6.6.1.el7_2-x86_64 u101-b00)
OpenJDK 64-Bit Server VM (build 24.95-b01, mixed mode)

#yum install maven

2. 安裝Maven

]# mvn -version
Apache Maven 3.0.5 (Red Hat 3.0.5-16)
Maven home: /usr/share/maven
Java version: 1.7.0_101, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.101-2.6.6.1.el7_2.x86_64/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.10.0-229.el7.x86_64", arch: "amd64", family: "unix"

3.安裝NEXUS

#tar zxvf  nexus-latest-bundle.tar.gz

解壓後會出現2個目錄nexus-2.8.1-01和 sonatype-work

因為NEXUS不推薦使用root使用者來啟動，所以新建使用者sonata,並把生成的2個目錄的使用者和組都改為sonata。

#mv nexus-2.8.1-01 nexus

#chown sonata:sonata -R nexus

#chown sonata:sonata -R sonatype-work

這樣就可以啟動nexus

# su sonata

$/opt/nexus/bin/nexus start

Starting Nexus OSS...
Started Nexus OSS.

也可以 新增Nexus為系統服務

#vi /usr/lib/systemd/system/nexus.service
