centos7.9部署nexus内网源服务器(yum,apt)

1、通过官网或其他方式下载安装包

2、安装Java，自行下载


[root@localhost ~]# ll
total 189992
-rw-------. 1 root root      1663 Oct  8 09:06 anaconda-ks.cfg
-rw-r--r--. 1 root root 194545143 Oct  8 17:43 jdk-8u241-linux-x64.tar.gz
[root@localhost ~]# tar xf jdk-8u241-linux-x64.tar.gz -C /usr/local/
[root@localhost ~]# tail -5 /etc/profile
export JAVA_HOME=/usr/local/jdk1.8.0_241/
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
[root@localhost ~]# source /etc/profile
[root@localhost ~]# java -version
java version "1.8.0_241"
Java(TM) SE Runtime Environment (build 1.8.0_241-b07)
Java HotSpot(TM) 64-Bit Server VM (build 25.241-b07, mixed mode)

3、解压nexus


[root@localhost ~]# tar xf nexus-3.42.0-01-unix.tar.gz -C /opt/
[root@localhost ~]# ll /opt/
total 0
drwxr-xr-x. 10 root root 181 Oct  8 18:40 nexus-3.42.0-01
drwxr-xr-x.  3 root root  20 Oct  8 18:40 sonatype-work

nexus-3.42.0-01：用于实现 nexus 功能
sonatype-work：用于存储数据

4、启动nexus


[root@localhost ~]# cd /opt/nexus-3.42.0-01/etc/
[root@localhost etc]# cat 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
 
nexus.hazelcast.discovery.isEnabled=true
 
配置文件无其他要求则保持默认即可
 
启动nexus
[root@localhost etc]# cd /opt/nexus-3.42.0-01/bin/
[root@localhost bin]# ll
total 32
drwxr-xr-x. 2 root root  4096 Oct  8 18:40 contrib
-rwxr-xr-x. 1 root root 18620 Sep 24  2022 nexus
-rw-r--r--. 1 root root    15 Sep 24  2022 nexus.rc
-rw-r--r--. 1 root root  1635 Sep 24  2022 nexus.vmoptions
[root@localhost bin]# ./nexus start

可以看到默认8081端口已启动

5、其他相关命令


#停止
./nexus stop
#重启
./nexus restart
#强制重新加载
./nexus force-reload
#查看状态
./nexus status

6、网页登陆

浏览器访问Nexus的web首页，进行登陆输入账号和密码
默认用户名为admin，密码在 sonatype-work/nexus3 目录下的 admin.password 文件中查看初始化密码。


[root@localhost ~]# cd /opt/sonatype-work/nexus3/
[root@localhost nexus3]# ls
admin.password  cache  elasticsearch  generated-bundles  karaf.pid  lock  orient  restore-from-backup
blobs           db     etc            instances          keystores  log   port    tmp
[root@localhost nexus3]# cat admin.password
