Linux下搭建maven服务器nexus

1.下载nexus
到http://download.sonatype.com/nexus/oss/nexus-2.11.1-01-bundle.zip这个地址下载，下载到的文件是nexus-2.11.1-01-bundle.zip
2.解压到相应的目录下
unzip nexus-2.11.1-01-bundle.zip，我这边是存放在/home/www/chendq/nexus 下
3.设置系统服务

[www@AY1302250124419032557 bin]$ cd /etc/init.d/
[www@AY1302250124419032557 init.d]$ cp /home/www/chendq/nexus/nexus-2.11.1-01/bin/nexus ./nexus

这里显示权限不够，切换为root用户

[www@AY1302250124419032557 init.d]$ su root
口令：
[root@AY1302250124419032557 init.d]# cp /home/www/chendq/nexus/nexus-2.11.1-01/bin/nexus ./nexus
[root@AY1302250124419032557 init.d]# chmod 755 nexus
[root@AY1302250124419032557 init.d]# chkconfig --add nexus                      #增加nexus服务
[root@AY1302250124419032557 init.d]#chkconfig --levels 345 nexus on             #添加运行级别3、4、5

有些机器可能不行，找/etc/目录下或者/etc/init.d/目录下的rc.local，
添加一行服务

/home/www/chendq/nexus/nexus-2.11.1-01/bin/nexus start

4.启动服务

[root@AY1302250124419032557 etc]# su www
[www@AY1302250124419032557 bin]$ cd ~/chendq/nexus/nexus-2.11.1-01/bin/
[www@AY1302250124419032557 bin]$ ./nexus start

修改端口号

[www@AY1302250124419032557 conf]$ cd /home/www/chendq/nexus/nexus-2.11.1-01/conf
[www@AY1302250124419032557 conf]$ vi nexus.properties 

把application-port=8081 修改为application-port=8981
重启nexus

首先查看下进程ps -ef |grep nexus
有进程的话kill掉
再启动nexus

判断是否启动成功
输入地址：http://IP地址:8981/nexus/index.html#welcome，是否显示页面
