一、依赖安装
1.上传程序包到/home下
2.配置Java环境
创建jdk目录
mkdir /mnt/java
解压程序包
tar -xvf /home/jdk-8u152-linux-x64.tar.gz -C /mnt/
修改环境变量
vi /etc/profile
#java
export JAVA_HOME=/mnt/java/jdk1.8.0_152/
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
source /etc/profile
验证jdk是否生效（如下则安装成功）
java -version
javaversion "1.8.0_152"
Java(TM)SE Runtime Environment (build 1.8.0_152-b16)
JavaHotSpot(TM) 64-Bit Server VM (build 25.152-b16, mixed mode)
3.配置maven
创建maven目录
mkdir /mnt/maven
解压程序包
unzip /home/apache-maven-3.5.0-bin.zip -d /mnt/maven/
修改环境变量
vi /etc/profile
添加：
#maven
export MAVEN_HOME=/mnt/maven/apache-maven-3.5.0
export PATH=${PATH}:${MAVEN_HOME}/bin
source /etc/profile
验证maven是否生效（如下则安装成功）
mvn -version
ApacheMaven 3.5.0 (ff8f5e7444045639af65f6095c62210b5713f426;2017-04-04T03:39:06+08:00)
Maven home: /mnt/maven/apache-maven-3.5.0

Defaultlocale: zh_CN, platform encoding: UTF-8
OS name:"linux", version: "3.10.0-862.el7.x86_64", arch:"amd64", family: "unix"
二、安装nexus
1.创建nexus目录
mkdir /mnt/nexus
2.解压程序包
tar -xvf /home/nexus-3.12.1-01-unix.tar.gz -C /mnt/nexus/
3.修改环境变量
vi /etc/profile
#nexus
export RUN_AS_USER=root
source /etc/profile
4.启动nexus
/mnt/nexus/nexus-3.12.1-01/bin/nexus start
5.查看日志
tail -f /mnt/nexus/sonatype-work/nexus3/log/nexus.log
6.登录nexus
