概述
Nexus Repository OSS 3是一个开源的仓库管理系统,提供了更加丰富的功能,而且安装、配置、使用起来也更加简单方便。OSS 3版本主要支持的仓库(Repository)包括如下:
- bower
- docker
- maven
- npm
- nuget
- pypi
- raw
- rubygems
- yum
其中,对于上述每种类型的Nexus仓库,都分别具有如下主要3种类型:
- hosted:本地仓库,可以将我们内部使用的一些Maven项目,发布到该类型仓库,供内部开发人员使用。
- proxy:代理仓库,用来代理远程公共仓库,比如Maven中央仓库。
- group:仓库组,用来合并多个类型(hosted/proxy)的仓库。
环境准备
- jdk: jdk-8u192-linux-x64.tar
- maven: apache-maven-3.6.0-bin.tar
- Nexus Repository OSS: https://www.sonatype.com/download-oss-sonatype
jdk和maven安装
1. 解压安装包
[root@localhost ~]# tar -xvf jdk-8u192-linux-x64.tar -C /usr/local/
[root@localhost ~]# tar -xvf apache-maven-3.6.0-bin.tar -C /usr/local/
注: .tar.gz后缀的需要用参数-zxvf
2. 配置环境变量
[root@localhost ~]# vi /etc/profile
在最后添加上
export JAVA_HOME=/usr/local/jdk1.8.0_192
export JRE_HOME=/usr/local/jdk1.8.0_192
export MAVEN_HOME=/usr/local/apache-maven-3.6.0
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$JAVA_HOME/bin:$MAVEN_HOME/bin:$PATH
3. 让配置生效
[root@localhost ~]# source /etc/profile
4. 验证
[root@localhost ~]# java -version
[root@localhost ~]# mvn -version
搭建nexus
1. 解压安装包
[root@localhost ~]# tar -xvf nexus-3.14.0-04-unix.tar -C /usr/local/
2. 修改配置
[root@localhost ~]# vi /usr/local/nexus-3.14.0-04/etc/nexus-default.properties
## DO NOT EDIT - CUSTOMIZATIONS BELONG IN $data-dir/etc/nexus.properties
##
# Jetty section
application-port=8081
application-host=0.0.0.0
nexus-args=${jetty.etc}/jetty.xml,${jetty.etc}/jetty-http.xml,${jetty.etc}/jetty-requestlog.xml
nexus-context-path=/
# Nexus section
nexus-edition=nexus-pro-edition
nexus-features=\
nexus-pro-feature
可以看到,nexus运行的端口为8081
3. 开放防火墙端口8081
[root@localhost ~]# firewall-cmd --zone=public --add-port=8081/tcp --permanent
[root@localhost ~]# sudo systemctl reload firewalld
4. 启动
[root@localhost ~]# /usr/local/nexus-3.14.0-04/bin/nexus start
提示不建议采用root账户
WARNING: ************************************************************
WARNING: Detected execution as "root" user. This is NOT recommended!
WARNING: ************************************************************
Starting nexus
查找nexus进程并杀掉
[root@localhost ~]# ps aux | grep nexus
[root@localhost ~]# kill 57340
添加新用户
[root@localhost ~]# useradd nexus
修改nexus文件的拥有者
[root@localhost ~]# chown -R nexus:nexus /usr/local/nexus-3.14.0-04/
[root@localhost ~]# chown -R nexus:nexus /usr/local/sonatype-work/
切换用户
[root@localhost ~]# su nexus
启动nexus
[nexus@localhost root]$ /usr/local/nexus-3.14.0-04/bin/nexus start
5. 登录访问
默认账户和密码 admin/admin123
6. 问题解决
System Requirement: max file descriptors [4096] likely too low, increase to at least [65536].
修改配置文件
[root@localhost ~]# vi /etc/security/limits.conf
新增下面两行
* soft nofile 65536
* hard nofile 65536
7. 开机启动
编辑文件
[root@localhost ~]# vi /etc/rc.d/rc.local
添加以下代码
su nexus -c '/usr/local/nexus-3.14.0-04/bin/nexus start'
在centos7中,/etc/rc.d/rc.local的权限被降低了,所以需要执行如下命令赋予其可执行权限
[root@localhost ~]# chmod +x /etc/rc.d/rc.local
nexus使用
设置maven使用本地仓库
1. 在maven的配置文件setting.xml加上以下代码
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
https://maven.apache.org/xsd/settings-1.0.0.xsd">

</settings>
打包提交到本地仓库
1. 在setting.xml文件增加配置
<servers>
<server>
<id>nexus-releases</id>
<username>admin</username>
<password>admin123</password>
</server>
<server>
<id>nexus-snapshots</id>
<username>admin</username>
<password>admin123</password>
</server>
</servers>
2. 在项目的pom.xml加上
<distributionManagement>
<repository>
<id>nexus-releases</id>
<name>Nexus ReleaseRepository</name>
<url>http://192.168.1.177:8081/repository/maven-releases/</url>
</repository>
<snapshotRepository>
<id>nexus-snapshots</id>
<name>Nexus SnapshotRepository</name>
<url>http://192.168.1.177:8081/repository/maven-snapshots/</url>
</snapshotRepository>
</distributionManagement>
3. 执行mvn deploy命令
