使用 Nexus 搭建 Maven私服仓库-CFANZ编程社区

下载并解压 nexus

[root@iZuf6i2yvneqsd64c75nm5Z software]# tar -zxvf Nexus-3.21.1-01-unix.tar.gz

解压后，有两个目录：

nexus-version
sonatype-work

[root@iZuf6i2yvneqsd64c75nm5Z software]# cd nexus-3.21.1-01/
[root@iZuf6i2yvneqsd64c75nm5Z nexus-3.21.1-01]# ll

启动/停止 nexus

[root@iZuf6i2yvneqsd64c75nm5Z nexus-3.21.1-01]# bin/nexus start

检测是否启动成功:
- ps aux | grep nexus
- jps → UnixLauncher

如果失败，并且 nexus 根目录下有 hs_err_pidXXX.log 之类的日志，并且报错：

#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 1890254848 bytes for committing reserved memory.
# Possible reasons:
#   The system is out of physical RAM or swap space
#   The process is running with CompressedOops enabled, and the Java Heap may be blocking the growth of the native heap
# Possible solutions:
#   Reduce memory load on the system
#   Increase physical memory or swap space
#   Check if swap backing store is full
#   Decrease Java heap size (-Xmx/-Xms)
#   Decrease number of Java threads
#   Decrease Java thread stack sizes (-Xss)
#   Set larger code cache with -XX:ReservedCodeCacheSize=
# This output file may be truncated or incomplete.
#
#  Out of Memory Error (os_linux.cpp:2756), pid=21219, tid=0x00007f7498513700
#
# JRE version:  (8.0_311-b11) (build )
# Java VM: Java HotSpot(TM) 64-Bit Server VM (25.311-b11 mixed mode linux-amd64 compressed oops)
# Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again
#

则可能是jvm启动参数设置的 -Xmx/-Xms 超过了机器内存。需要修改jvm启动参数：

vim bin/nexus.vmoptions

-Xms512m
-Xmx512m
-XX:MaxDirectMemorySize=512m

访问

默认端口：8081（可在 etc/nexus-default.properties 文件中修改）

地址：http://ip:8081

右上角登录：

默认账户：admin
默认密码：sonatype-work/nexus3/admin.password 文件中

登录成功后修改密码。

使用

编辑本地 maven 的 Settings.xml

配置 servers 内容

<servers>
 <server>
	<id>releases</id>        
	<username>admin</username>   
	<password>密码</password>  
</server>
<server>
	<id>snapshots</id>     
	<username>admin</username> 
	<password>密码</password>   
</server>
</servers>

idea 配置 deploy 时上传到私服

配置 pom.xml

		<distributionManagement>
      <repository>
            <id>releases</id>
            <url>http://xxx:8081/repository/maven-releases/</url>
        </repository>
        <snapshotRepository>
            <id>snapshots</id>
            <url>http://xxx:8081/repository/maven-snapshots/</url>
        </snapshotRepository>
    </distributionManagement>

maven 执行 deploy 命令，控制台中有以下输出。

在这里插入图片描述

指定maven地址下载jar包到本地

将项目pom.xml文件的repositories标签里添加上

<repository>
    <id>snapshots</id>
    <name>Snapshots Repository</name>
    <url>http://xxx:8081/repository/maven-snapshots</url>
    <snapshots>
