3. 系统环境准备

Nexus依赖Java运行环境，需要提前安装配置。学习交流加群风哥QQ113257174

步骤1：安装Java运行环境

# 安装OpenJDK 17
# yum install -y java-17-openjdk java-17-openjdk-devel

# 验证Java版本
# java -version

OpenJDK Runtime Environment (Red_Hat-17.0.13.0.11-1) (build 17.0.13+11-LTS)
OpenJDK 64-Bit Server VM (Red_Hat-17.0.13.0.11-1) (build 17.0.13+11-LTS, mixed mode, sharing)

# 配置JAVA_HOME
# vi /etc/profile.d/java.sh
export JAVA_HOME=/usr/lib/jvm/java-17-openjdk
export PATH=$JAVA_HOME/bin:$PATH

# 使配置生效
# source /etc/profile.d/java.sh

步骤2：创建Nexus用户和目录

# 创建nexus用户
# useradd -r -s /sbin/nologin nexus

# 创建目录
# mkdir -p /opt/nexus
# mkdir -p /data/nexus-data

# 移动解压文件
# mv nexus-3.72.0-04 /opt/nexus/
# mv sonatype-work /data/nexus-data

# 设置权限
# chown -R nexus:nexus /opt/nexus

a1b2c3d4-e5f6-7890-abcd-ef1234567890

# 访问Web界面
# http://192.168.1.51:8081

# 登录后修改密码
# 用户名: admin
# 初始密码: a1b2c3d4-e5f6-7890-abcd-ef1234567890
# 新密码: fgedu_nexus_password_2026

# 验证服务端口
# netstat -tlnp | grep 8081
tcp 0 0 0.0.0.0:8081 0.0.0.0:* LISTEN 40125/java

风哥提示：Nexus首次启动需要较长时间初始化数据库，请耐心等待。初始密码存储在admin.password文件中，登录后请立即修改。

+ @fgedu/test-package@1.0.0

7. 生产环境最佳实践

在生产环境中部署Nexus需要考虑性能优化、安全加固和备份恢复。

性能优化配置

# 配置JVM内存
# vi /opt/nexus/nexus-3.72.0-04/bin/nexus.vmoptions
-Xms4g
-Xmx4g
-XX:MaxDirectMemorySize=4g

# 配置任务调度
# 导航到 Administration -> System -> Tasks
# 创建清理任务
Name: Cleanup service
Task type: Admin – Cleanup service using blob store
Blob store: default
Schedule: Daily at 02:00

# 创建重建索引任务
Name: Rebuild index
Task type: Repair – Rebuild repository search
Repository: All repositories
Schedule: Weekly on Sunday at 03:00

# 配置Blob存储
# 导航到 Repository -> Blob Stores -> Create blob store
Name: maven-blob
Type: File
Path: /data/nexus-blob/maven

# 配置压缩存储
# 导航 to Administration -> Repository -> Compression
Enable compression: true

备份与恢复

# 创建备份任务
# 导航到 Administration -> System -> Tasks -> Create task
Name: Database backup
Task type: Admin – Export databases for backup
Backup location: /backup/nexus
Schedule: Daily at 01:00

# 手动执行备份
# 导航到 Administration -> System -> Tasks
# 选择备份任务，点击 “Run”

# 输出案例如下：
Task ‘Database backup’ started at 2026-04-04 01:00:00
Exporting database…
Export completed successfully at 2026-04-04 01:05:30

# 恢复数据库
# 停止Nexus服务
# systemctl stop nexus

# 恢复数据
# cd /opt/nexus/nexus-3.72.0-04
# java -jar lib/support/nexus-orient-console.jar
CONNECT PLOCAL:/data/nexus-data/sonatype-work/nexus3/db/component admin admin
IMPORT DATABASE /backup/nexus/component-20260404.zip
DISCONNECT

# 启动Nexus服务
# systemctl start nexus

生产环境建议：Nexus建议部署在高性能服务器上，内存至少8GB。建议配置独立的Blob存储磁盘。定期备份数据库和配置文件。建议配置LDAP认证集成企业用户体系。定期清理无用构件释放存储空间。建议配置监控告警，及时发现和处理问题。
