CentOS安装nexus(Maven仓库管理器)

2022-06-04 07:28:14

Nexus是一个强大的Maven仓库管理器，
它极大地简化了自己内部仓库的维护和外部仓库的访问。
利用Nexus你可以只在一个地方就能够完全控制访问和部署在你所维护仓库中的每个Artifact。
Nexus是一套“开箱即用”的系统不需要数据库，它使用文件系统加Lucene来组织数据。
Nexus使用ExtJS来开发界面，利用Restlet来提供完整的REST APIs，通过m2eclipse与Eclipse集成使用。
Nexus支持WebDAV与LDAP安全身份认证。

我的准备：

 CentOS Linux release 7.1.1503 (Core)
 nexus-2.11.1-01-bundle.tar.gz
 jdk-8u60-linux-x64

注：最终启动，如果远程访问关闭，或者是stoped的nexus的jre版本和本地jre的version不符合（一般1.7就ok）！

1：解压：

[root@CentOS-Slave1 install-files]# tar zxvf nexus-2.11.1-01-bundle.tar.gz 
-rw-r--r--. 1 root root 71817045 Oct 18 15:17 nexus-2.11.1-01-bundle.tar.gz
drwxr-xr-x. 8 root root     4096 Dec 17  2014 nexus-2.11.1-01
drwxr-xr-x. 3 root root       35 Dec 17  2014 sonatype-work
注：安装nexus,本地仓库默认的jar包存储位置是:/sonatype-work/nexus/storage/central。由于Central仓库占用存储较大,所以要注意存储位置。

2：移动合适位置/home/nexus：

[root@CentOS-Slave1 install-files]# mv nexus-2.11.1-01 /home/nexus/
[root@CentOS-Slave1 install-files]# mv sonatype-work/ /home/nexus
[root@CentOS-Slave1 install-files]# cd /home/nexus/
[root@CentOS-Slave1 nexus]# ll
total 4
drwxr-xr-x. 8 root root 4096 Dec 17  2014 nexus-2.11.1-01
drwxr-xr-x. 3 root root   35 Dec 17  2014 sonatype-work

3：修改配置文件1：/home/nexus/nexus-2.11.1-01/conf/nexus.properties
………………
# Sonatype Nexus
# ==============
# This is the most basic configuration of Nexus.

# Jetty section
# 配置端口信息
application-port=8081
application-host=0.0.0.0
nexus-webapp=${bundleBasedir}/nexus
#配置IP端口访问
#http://192.168.10.56:8081/nexus/可修改为: /
nexus-webapp-context-path=/nexus

# Nexus section
#配置work目录地址,Maven仓库JAR缓存地址,可修改其他地址eg:${bundleBasedir}/nexus-work/nexus 
nexus-work=${bundleBasedir}/../sonatype-work/nexus
runtime=${bundleBasedir}/nexus/WEB-INF
4：修改配置文件2：/home/nexus/nexus-2.11.1-01/bin/nexus
………………
#NEXUS_HOME=".."
#如果目录改变配置,如果修改了运行路径
NEXUS_HOME="/home/nexus/nexus-2.11.1-01"
……………………
#RUN_AS_USER=
#nexus启动用户
RUN_AS_USER=root
注：nexus很依赖于jdk,编写,所以必须安装好jdk并设置环境变量/etc/profile并生效！备注附件！
[root@CentOS-Slave1 metrics]# pwd
/home/nexus/nexus-2.11.1-01/nexus/WEB-INF/classes/org/sonatype/nexus/webapp/metrics
[root@CentOS-Slave1 metrics]# ls
DeadlockHealthCheckProvider.class  HealthCheckMediator.class  MetricsModule$1.class  MetricsModule$2.class  MetricsModule.class
5：启动nexus服务：
[root@CentOS-Slave1 bin]# ./nexus start

7：nexus开机启动：

[root@CentOS-Slave1 bin]# pwd
/home/nexus/nexus-2.11.1-01/bin
[root@CentOS-Slave1 bin]# ls
jsw  nexus  nexus.bat
[root@CentOS-Slave1 bin]# cp nexus /etc/rc.d/init.d/
[root@CentOS-Slave1 bin]# cd /etc/rc.d/init.d/
[root@CentOS-Slave1 init.d]# ls
functions  jexec  mysql  netconsole  network  nexus  README
[root@CentOS-Slave1 init.d]# chkconfig --add nexus
[root@CentOS-Slave1 init.d]# chkconfig --list | grep nexus 

Note: This output shows SysV services only and does not include native
      systemd services. SysV configuration data might be overridden by native
      systemd configuration.

      If you want to list systemd services use 'systemctl list-unit-files'.
      To see services enabled on particular target use
      'systemctl list-dependencies [target]'.

nexus          	0:off	1:off	2:off	3:off	4:off	5:off	6:off
[root@CentOS-Slave1 init.d]# chkconfig nexus on
[root@CentOS-Slave1 init.d]# chkconfig --list | grep nexus 

Note: This output shows SysV services only and does not include native
      systemd services. SysV configuration data might be overridden by native
      systemd configuration.

      If you want to list systemd services use 'systemctl list-unit-files'.
      To see services enabled on particular target use

nexus          	0:off	1:off	2:on	3:on	4:on	5:on	6:off

问题1：

[root@CentOS-Slave1 bin]# ./nexus start
****************************************
WARNING - NOT RECOMMENDED TO RUN AS ROOT
****************************************
If you insist running as root, then set the environment variable RUN_AS_USER=root before running this script.

解决1：上：4：修改配置文件2：/home/nexus/nexus-2.11.1-01/bin/nexus ---> RUN_AS_USER=root

Apache Snapshots: 用了代理ApacheMaven仓库快照版本的构件仓库
Central: 用来代理maven*仓库中发布版本构件的仓库
Central M1 shadow: 用于提供*仓库中M1格式的发布版本的构件镜像仓库
Codehaus Snapshots: 用来代理CodehausMaven 仓库的快照版本构件的仓库
Releases: 用来部署管理内部的发布版本构件的宿主类型仓库
Snapshots:用来部署管理内部的快照版本构件的宿主类型仓库
