关闭防火墙

# systemctl stop firewalld

# systemctl  disable firewalld

# iptables  -F

二、安装nexus

# rpm -e --nodeps $(rpm -qa | grep -i openjdk)

#  wget  https://sonatype-download.global.ssl.fastly.net/nexus/3/nexus-3.5.0-02-unix.tar.gz

#  tar  zxvf nexus-3.5.0-02-unix.tar.gz      -C     /opt

# tar   zxvf  jdk-8u131-linux-x64.tar.gz     -C     /opt

# ll   /opt/

# groupadd -g 2018  nexus

# useradd  -u 2018 -g  2018 nexus

# echo "123456" | passwd  --stdin  nexus

# echo "JAVA_HOME=/opt/jdk1.8.0_131"   >> /etc/profile.d/jdk.sh

#  source  /etc/profile.d/jdk.sh

# echo "export PATH=$JAVA_HOME/bin:$PATH" >>  /etc/profile.d/jdk.sh

# source  /etc/profile.d/jdk.sh

# java -version

# vim /opt/nexus-3.5.0-02/bin/nexus.rc

run_as_user="nexus"

# vim /opt/nexus-3.5.0-02/bin/nexus 

INSTALL4J_JAVA_HOME="/opt/jdk1.8.0_131"

# vim /etc/systemd/system/nexus.service

生成keystore文件：

# keytool  \

# vim /opt/nexus-3.5.0-02/etc/jetty/jetty-https.xml

# systemctl  restart  nexus

# systemctl  status  nexus

# systemctl  enable  nexus

# ss  -tan | grep 8081

# ss  -tan | grep 8443

三、测试

浏览器访问http://192.168.1.101:8081

浏览器访问https://192.168.1.101:8443

默认登录用户密码：admin/admin123

四、更新 nexus  maven索引

需要下载如下三个文件：

indexer-cli-6.0.0.jar

nexus-maven-repository-index.gz

nexus-maven-repository-index.properties

# wget  http://repo.maven.apache.org/maven2/.index/nexus-maven-repository-index.gz

# wget http://repo.maven.apache.org/maven2/.index/nexus-maven-repository-index.properties

# wegt http://central.maven.org/maven2/org/apache/maven/indexer/indexer-cli/6.0.0/indexer-cli-6.0.0.jar

相关下载链接：

http://repo.maven.apache.org/maven2/.index

http://central.maven.org/maven2/org/apache/maven/indexer/indexer-cli

#  mkdir  -p  /opt/maven

# cp indexer-cli-6.0.0.jar nexus-maven-repository-index.gz nexus-maven-repository-index.properties   /opt/maven

# cd  /opt/maven

# java -jar indexer-cli-6.0.0.jar -u nexus-maven-repository-index.gz  -d  indexer

等待程序运行完成之后可以发现/opt/maven/indexer文件夹下出现了很多文件

将/opt/maven/indexer下的文件放置到 /opt/sonatype-work/nexus3/indexer/central-ctx 目录下

# mkdir  -p  /opt/sonatype-work/nexus3/indexer/central-ctx

# cp  -r  /opt/maven/indexer/*   /opt/sonatype-work/nexus3/indexer/central-ctx

# chown -R nexus:nexus  /opt/sonatype-work

# systemctl restart nexus 

# systemctl status nexus
