1. 准备环境

搭建系统环境：Red Hat Enterprise Linux release 8.7
先将需要用到的压缩包（jdk-8u251-linux-x64.tar.gz、apache-maven-3.6.2-bin.tar.gz、nexus-3.31.1-01-unix.tar.gz）一并上传至/usr/local/src文件夹下，再执行初始化脚本: source init.sh 8.7，脚本内容如下：

#!/bin/bash#!/bin/bash
if [ -z $1 ]then echo '$1 is not exists or is empty'exit
fiecho "[BaseOS]

" > /etc/yum.repos.d/online.repoecho vers:$1
sed -i "s/8/$1/g" /etc/yum.repos.d/online.repodnf install -y vimcd /usr/local/src/
tar -zxvf apache-maven-3.6.2-bin.tar.gz
tar -zxvf jdk-8u251-linux-x64.tar.gzecho "export MAVEN_HOME=/usr/local/src/apache-maven-3.6.2" >> /etc/profile
echo "export JAVA_HOME=/usr/local/src/jdk1.8.0_251" >> /etc/profile
echo "export PATH=\$PATH:\$MAVEN_HOME/bin:\$JAVA_HOME/bin" >> /etc/profile
source /etc/profilesystemctl stop firewalld && systemctl disable firewalld

执行完init.sh后，编辑maven的配置文件settings.xml, 在标签里面天下如下内容：
vim /usr/local/src/apache-maven-3.6.2/conf/settings.xml

aliyunmaven*aliyunhttps://maven.aliyun.com/repository/public

nexus-163*Nexus 163http://mirrors.163.com/maven/repository/maven-public/

检测下环境是否初始化成功,如下图所示表示环境准备完毕

mvn -v

2. 安装nexus

创建用户

useradd nexus
echo 'nexus'|passwd --stdin nexus

解压nexus的压缩包

tar -zxvf nexus-3.31.1-01-unix.tar.gz

将nexus解压后的两个目录以及目录下的子目录和文件的属主属组改成nexus

chown -R nexus:nexus nexus-3.31.1-01
chown -R nexus:nexus sonatype-work

修改/etc/security/limits.conf，

vim /etc/security/limits.conf
添加如下内容
nexus - nofile 65536

编辑/usr/local/src/nexus-3.31.1-01/bin/nexus.rc文件

vim /usr/local/src/nexus-3.31.1-01/bin/nexus.rc

编辑/usr/local/src/nexus-3.31.1-01/bin/nexus

vim /usr/local/src/nexus-3.31.1-01/bin/nexus
将INSTALL4J_JAVA_HOME_OVERRIDE前面的#去掉，并且赋值jdk的路径
INSTALL4J_JAVA_HOME_OVERRIDE=/usr/local/src/jdk1.8.0_251

编辑/etc/systemd/system/nexus.service
vim /etc/systemd/system/nexus.service

[Unit]
Description=nexus service
After=network.target[Service]
Type=forking
LimitNOFILE=65535
ExecStart=/usr/local/src/nexus-3.31.1-01/bin/nexus start
ExecStop=/usr/local/src/nexus-3.31.1-01/bin/nexus stop
User=nexus
Restart=on-abort
TimeoutSec=600[Install]
WantedBy=multi-user.target

启动nexus

systemctl daemon-reload
systemctl start nexus
查看nexus状态
systemctl status nexus

3. 配置nexus

接下来就来开始访问nexus
访问地址：192.168.225.25:8081

登录下

登录以后需要初始设置一下以及修改登陆密码

4. 使用nexus

创建私服代理仓库


这里填写阿里云仓库地址








在maven的settings.xml里面添加私服仓库地址,把下面这个添加在标签里面即可

maven-public*maven-publichttp://192.168.225.25:8081/repository/maven-public/

5. 手动上传jar包到私服仓库

待更新
