Nexus|Nexus Install and configure NexusInstallandconfigure

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.rpmvim /etc/profileexport 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/profilejava -versionjavac -version

安装nexus

tar -zxvf nexus-3.28.1-01-unix.tar.gz -C /home/nexusvim /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 nexusnetstat -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]'. nexus0:off1:off2:on3:on4:on5:on6:off
