Install-Nexus3

1. 安装 Nexus3

1. 安装

# 下载安装包
wget https://download.sonatype.com/nexus/3/nexus-3.2.0-01-unix.tar.gz -O /usr/local/nexus/nexus-3.2.0-01-unix.tar.gz

# 创建安装目录
mkdir /usr/local/nexus/

# 解压安装包
tar -zxvf nexus-3.2.0-01-unix.tar.gz -C /usr/local/nexus/

# 设置 NEXUS3 运行用户为 root
vim /usr/local/nexus/nexus-3.2.0-01/bin/nexus.rc
run_as_user="root"

# 修改 NEXUS3 启动时要使用的 JDK 版本
vim /usr/local/nexus/nexus-3.2.0-01/bin/nexus
INSTALL4J_JAVA_HOME_OVERRIDE=/usr/local/java/jdk1.8.0/

# 修改 NEXUS3 默认端口 (可选)
vim /usr/local/nexus/nexus-3.2.0-01/etc/nexus-default.properties
application-port=18081

# 关闭防火墙，并开启远程访问端口 18081
firewall-cmd --zone=public --add-port=18081/tcp --permanent
firewall-cmd reload
firewall-cmd --list-all

# 创建用户并授权（跳过）
adduser nexus
passwd nexus
chown -R nexus /usr/local/java
chown -R nexus /usr/local/nexus

2. 注册为服务

新建一个nexus.service文件：

vim /usr/lib/systemd/system/nexus.service

[Unit]
Description=nexus
After=network.target

[Service]
Type=forking
# Nexus的执行文件
ExecStart=/usr/local/nexus/nexus-3.2.0-01/bin/nexus start
ExecStop=/usr/local/nexus/nexus-3.2.0-01/bin/nexus stop
User=root
Restart=on-abort

[Install]
WantedBy=multi-user.target

3. 启动

# 重启守护进程
systemctl daemon-reload

# 启动 NEXUS3
systemctl enable nexus && systemctl start nexus

# 查看状态
systemctl status nexus

# 新版本查看密码，老版本默认（admin/admin123）
cat /usr/local/nexus/sonatype-work/nexus3/admin.password

# 查看开机自启
systemctl list-unit-files | grep nexus

# 关闭开机自启
systemctl disable nexus

4. 仓库地址

序号	类型	种类	URL	备注
1	Maven	Proxy	https://repo1.maven.org/maven2/	中央仓库
2	Maven	Proxy	https://maven.aliyun.com/repository/public	阿里云仓库
3	Maven	Hosted		本地仓库
-	-	-	-	-
1	NPM	Proxy	https://registry.npmjs.org	中央仓库
2	NPM	Proxy	https://registry.npm.tabao.org	淘宝仓库
3	NPM	Proxy	https://registry.npmmirror.com	淘宝仓库
4	NPM	Hosted		本地仓库
-	-	-	-	-
1	Docker	Group	http-18083	组合
2	Docker	Proxy	https://registry-1.docker.io	中央仓库
3	Docker	Proxy	https://registry.cn-hangzhou.aliyuncs.com	阿里云仓库
4	Docker	Hosted	http-18082	本地仓库

Docker仓库需要配置http地址，并重新加载 vim /etc/docker/daemon.json

{
  "registry-mirrors": ["https://rv4ppfhe.mirror.aliyuncs.com"],
  "exec-opts": ["native.cgroupdriver=systemd"],
  "insecure-registries": [
        "192.168.137.102:5000",
        "192.168.137.102:5080",
        "192.168.137.102:18082"
  ]
}

5. 测试

# 重启Docker
systemctl daemon-reload && service docker restart

# 查看配置的地址是否生效
docker info

# 登录仓库
docker login 192.168.137.102:18082

# 拉取测试镜像
docker pull alpine

# 重新打Tag
docker tag alpine:latest 192.168.137.102:18082/pi-diginn/alpine:latest

# 推送到私服
docker push 192.168.137.102:18082/pi-diginn/alpine:latest

# 从私服拉取镜像 走Group代理
docker pull 192.168.137.102:18083/pi-diginn/alpine:latest
