一，安裝Nexus

安裝java, nexus要求特定的JAVA版本

下載JAVA RPM包

https://www.oracle.com/java/technologies/javase/javase-jdk8-downloads.html

rpm -ivh jdk-8u271-linux-x64.rpm



vim /etc/profile

export JAVA_HOME=/usr/java/jdk1.8.0_271-amd64
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin

 source /etc/profile



java -version

javac -version

安裝nexus

tar -zxvf nexus-3.28.1-01-unix.tar.gz -C /home/nexus



vim /home/nexus/nexus-3.28.1-01/bin/nexus

 INSTALL4J_JAVA_HOME_OVERRIDE=/usr/java/jdk1.8.0_271-amd64

./nexus start

如果JAVA版本不對(duì)，會(huì)出現(xiàn)如下提示：

No suitable Java Virtual Machine could be found on your system.
The version of the JVM must be at least 1.8 and at most 1.8.
Please define INSTALL4J_JAVA_HOME to point to a suitable JVM.

檢查NEXUS是否運(yùn)行

ps -ef |grep nexus

netstat -natp |grep 8081

二，Nexus加入服務(wù)并自啟動(dòng)

CentOS7配置nexus開機(jī)自啟動(dòng)

新建nexus啟動(dòng)腳本

進(jìn)入/etc/init.d目錄，新建腳本文件nexus

進(jìn)入/etc/init.d
[root@linux_maven etc]# cd /etc/init.d/

新建腳本文件nexus
[root@linux_maven init.d]# vim nexus

腳本內(nèi)容:

#!/bin/bash
#chkconfig:2345 20 90
#description:nexus
#processname:nexus
 
export JAVA_HOME=/usr/java/jdk1.8.0_271-amd64
 
case $1 in
        start) su root /usr/local/nexus3.21/bin/nexus start;;
        stop) su root /usr/local/nexus3.21/bin/nexus stop;;
        status) su root /usr/local/nexus3.21/bin/nexus status;;
        restart) su root /usr/local/nexus3.21/bin/nexus restart;;
        dump) su root /usr/local/nexus3.21/bin/nexus dump;;
        console) su root /usr/local/nexus3.21/bin/nexus console;;
        *) echo "Usage: nexus {start|stop|run|run-redirect|status|restart|force-reload}"
esac

設(shè)置腳本權(quán)限

chmod +x /etc/init.d/nexus 

使用service命令使用nexus

 service nexus status
WARNING: ************************************************************ 
WARNING: Detected execution as "root" user.  This is NOT recommended!
WARNING: ************************************************************
nexus is running.

添加到開機(jī)啟動(dòng)

 chkconfig nexus on

查看nexus開機(jī)啟動(dòng)

[root@linux_maven ~]# chkconfig --list nexus
 
Note: This output shows SysV services only and does not include native
      systemd services. SysV configuration data might be overridden by native
      systemd configuration.
 
      If you want to list systemd services use 'systemctl list-unit-files'.
      To see services enabled on particular target use
      'systemctl list-dependencies [target]'.
 
nexus           0:off   1:off   2:on    3:on    4:on    5:on    6:off

啟動(dòng)nexus

ps -ef |grep nexus |xargs kill -9

service start nexus

三，配置LDAP(AD)認(rèn)證

LDAP server address
used  AD server

search base DN:
dc=fj,dc=com

username or DN:
AD管理員權(quán)限帳號(hào)

至此完成安裝，并配置使用LDAP認(rèn)證。
