Ubuntu部署Nexus私有仓库

简介

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

安装Nexus

1、下载包

此次安装部署在Ubuntu系统下。系统版本为Ubuntu-20.04.2 LTS。nexus需要用到jdk环境，这里采用jdk8的环境即可。官网下载地址：https://help.sonatype.com/en/download-archives---repository-manager-3.html。选择包时也选择jdk8的即可如下图

下载完后传到服务器上进行解压,或者直接在服务器上使用wget方式下载不过这种访问有时候下载慢。

2、解压包

root@k8s-master01:/app/soft# wget  https://download.sonatype.com/nexus/3/nexus-3.70.2-01-java8-unix.tar.gz
root@k8s-master01:/app/soft# tar xf nexus-3.70.2-01-java8-unix.tar.gz
root@k8s-master01:/app/soft# ls
nexus-3.70.2-01  nexus-3.70.2-01-java8-unix.tar.gz  sonatype-work

3、创建软连接

创建软连接是方便后续升级。部署是采用二进制的方式后续只需要把这个软连接重新指向新版本的包路径即可

root@k8s-master01:/app/soft# ln -s /app/soft/nexus-3.70.2-01 /usr/local/nexus
root@k8s-master01:~# ll /usr/local/
total 44
drwxr-xr-x 11 root root 4096 Oct  3 09:46 ./
drwxr-xr-x 14 root root 4096 Feb  2  2021 ../
drwxr-xr-x  3 root root 4096 Sep  6 16:16 bin/
drwxr-xr-x  2 root root 4096 Feb  2  2021 etc/
drwxr-xr-x  2 root root 4096 Feb  2  2021 games/
drwxr-xr-x  2 root root 4096 Feb  2  2021 include/
lrwxrwxrwx  1 root root   28 Sep  6 16:12 jdk -> /usr/local/src/jdk1.8.0_201/
drwxr-xr-x  3 root root 4096 Feb  2  2021 lib/
lrwxrwxrwx  1 root root    9 Feb  2  2021 man -> share/man/
lrwxrwxrwx  1 root root   25 Oct  3 09:46 nexus -> /app/soft/nexus-3.70.2-01/
drwxr-xr-x  2 root root 4096 Feb  2  2021 sbin/
drwxr-xr-x  4 root root 4096 Feb  2  2021 share/
drwxr-xr-x  5 root root 4096 Sep 10 22:10 src/
drwxr-xr-x  3 root root 4096 Sep  6 16:16 Worker/

4、创建启动文件

由于是采用二进制部署的在对nexus进行启动、停止操作不方便。需要创建一个启动service文件来管理

root@k8s-master01:/app/soft# vim /lib/systemd/system/nexus.service
[Unit]
Description=nexus service
After=network.target

[Service]
Type=forking
ExecStart=/usr/local/nexus/bin/nexus start
ExecStop=/usr/local/nexus/bin/nexus stop
# 这里一般要用普通用户来启动它，用root也可以不过在日志文件里它会提示不建议采用root来
User=root
Restart=on-abort

[Install]
WantedBy=multi-user.target

5、启动nexus

root@k8s-master01:/app/soft# systemctl daemon-reload
root@k8s-master01:/app/soft# systemctl start nexus
root@k8s-master01:/app/soft# tail -f /var/log/syslog
