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 \

-alias nexus \
-keypass nexus@123 \

# 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
