3.安装nexus:我是安装在挂载盘符 /usr/local上

------切换到下载目录
#cd /usr/local
------下载压缩包
#wget  https://sonatype-download.global.ssl.fastly.net/nexus/oss/nexus-2.12.0-01-bundle.tar.gz

# mv nexus-2.12.0-01 nexus

4.安装nexus到系统服务

------复制脚本到/etc/init.d
#sudo cp nexus/bin/nexus /etc/init.d/nexus
------编辑刚刚复制过去的脚本：我用root用户启动，但官方不推荐
#vi /etc/init.d/nexus
------修改：NEXUS_HOME="/mnt/nexus"；RUN_AS_USER=root
------添加系统服务
#chkconfig --add nexus
#chkconfig --levels 345 nexus on
------启动nexus
#service nexus start

5.修改nexus默认用户名密码
