Nexus Install and configure

一，安装Nexus

安装java, nexus要求特定的JAVA版本

下载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

安装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版本不对，会出现如下提示：

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.

检查NEXUS是否运行

ps -ef |grep nexus

netstat -natp |grep 8081

二，Nexus加入服务并自启动

CentOS7配置nexus开机自启动

新建nexus启动脚本

进入/etc/init.d目录，新建脚本文件nexus

进入/etc/init.d
[root@linux_maven etc]# cd /etc/init.d/

新建脚本文件nexus
[root@linux_maven init.d]# vim nexus

脚本内容:

#!/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

设置脚本权限

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.

添加到开机启动

 chkconfig nexus on

查看nexus开机启动

[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

启动nexus

ps -ef |grep nexus |xargs kill -9

service start nexus

三，配置LDAP(AD)认证

LDAP server address

search base DN:
dc=fj,dc=com

username or DN:
AD管理员权限帐号

至此完成安装，并配置使用LDAP认证。
