1. Introduction to Nexus
For Maven, warehouses are divided into two categories: local warehouses and remote warehouses. There are three specialized Maven warehouse management software that can be used to help us build private servers: chiva, Artifactory and Nexus. Nexus is currently the most popular Maven warehouse management software. Nexus includes the concept of various types of warehouses, including proxy warehouses, host warehouses, warehouse groups, etc. Each warehouse provides a wealth of practical configuration parameters, which is convenient for users to customize according to their needs.
Two, 2.X environment installation and deployment
Take the latest version of 2.X as an example, the version number is 2.14.16
1. Nexus official website download address
https://www.sonatype.com/download-oss-sonatype
2.X version download link: https://help.sonatype.com/repomanager2/download
3.X version download address: https://help.sonatype.com/repomanager3/download
2. Unzip to local
tar -xzvf nexus-2.14.16-01-bundle.tar.gz
3. Modify the Nexus port (default is 8081)
My query port here is already occupied, so I need to modify the port, vi nexus.properties, here I modify the application-port to 8090
[root@yang opt]# netstat -aon | grep "8081"

[root@yang opt]# lsof -i :8081

5. Modify the startup file
/opt/nexus-2.14.16-01/bin/nexus add root startup, or add nexus user (useradd nexus),
否则启动报错If you insist running as root, then set the environment variable RUN_AS_USER=root before running this script.
Modify RUN_AS_USER=root //Be careful to delete the # in front
Modify the JDK path vi wrapper.conf (./bin/jsw/conf/wrapper.conf)
Modify the parameter wrapper.java.library.path.1=/opt/jdk1.8.0_151/bin/

Three, 3.X environment installation and deployment
There are some differences between 3.x and 2.x, here are also recorded
3.X version download address: https://help.sonatype.com/repomanager3/download
1. Unzip
tar -xzvf nexus-3.21.2-03-unix.tar.gz
After decompression, there are two folders nexus-3.21.2-03 and sonatype-work
2. Modify the default port of Nexus
There is a slight change in the path, the configuration file is under the path /opt/nexus-3.21.2-03/etc vi nexus-default.properties
Modify here to application-port=8091
3. Turn on the firewall
vi /etc/sysconfig/iptables
添加：-A INPUT -p tcp -m state --state NEW -m tcp --dport 8091 -j ACCEPT
service iptables restart
4. Add a startup user
After testing, there are quite a lot of problems when using root to start.
useradd nexus
Modify the user and user group to which the file belongs:
chown -R nexus:nexus /opt/nexus-3.21.2-0
chown -R nexus:nexus /opt/sonatype-work
drwxr-xr-x 9 nexus nexus 4096 Mar 24 20:09 nexus-3.21.2-03
