Maven

私服 nexus

前面两节说了一下Maven仓库。

这里我们使用nexus搭建Maven仓库——私服

1.下载软件：
nexus下载地址使用Linux环境下载 tgz包
http://www.sonatype.org/nexus/go
2.将nexus放在Linux下，使用的是root账号
3.解压 tar -zvxf 文件名
4.目录下面生成一个

5.进入下面的bin目录
6.使用

7.提示警告：
warning - not recommended to run as root
解决方法：
A.临时生效
export RUN_AS_USER=root
B.加入系统变量
vi /etc/profile 加入export RUN_AS_USER=root
8.没有提示错误，但是还是启动不了
日志错误信息：

问题原因：
JDK版本过低，我使用的JDK1.6但是这个nexus需要7才可以。所以找个低版本的下载
下载历史版本地址：
http://www.sonatype.org/nexus/archived
我下载一个1.9.2

重新下载后，将***.tag拷到Linux中
9.解压
tar -zvxf nexus-oss-webapp-1.9.2-bundle.tar.gz
10.进入nexus-oss-webapp-1.9.2
cd nexus-oss-webapp-1.9.2
11.启动：

12.登陆：
