使用Nexus搭建maven私服

一、基础环境

1、系统最大文件数修改

echo "*   soft    nofile  65535" >> /etc/security/limits.conf
echo "*   hard    nofile  65535" >> /etc/security/limits.conf

2、关闭防火墙及selinux

systemctl stop firewalld && systemctl disable firewalld

sed -i 's/^SELINUX=.*/SELINUX=disabled/' /etc/selinux/config
setenforce 0

二、Java

rpm -ivh jdk-8u202-linux-x64.rpm

cat >> /etc/profile <<EOF
#set java environment
export JAVA_HOME=/usr/java/jdk1.8.0_202-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
EOF

source /etc/profile

三、Maven

1、获取maven

https://maven.apache.org/download.cgi

2、安装maven

• maven系统要求
  
• 解压安装

tar -xvf apache-maven-3.6.3-bin.tar.gz

mv apache-maven-3.6.3 /usr/local/maven

• 配置环境变量

cat >> /etc/profile <<EOF
export MAVEN_HOME=/usr/local/maven
export PATH=\$PATH:\$MAVEN_HOME/bin
EOF

source /etc/profile

• 版本查看

mvn -v

四、Nexus

1、获取Nexus

https://www.sonatype.com/download-oss-sonatype

2、安装Nexus

tar -xvf nexus-3.23.0-03-unix.tar.gz

mv nexus-3.23.0-03 /usr/local/nexus

3、配置文件

#修改端口号等，一般默认即可
vim /usr/local/nexus/etc/nexus-default.properties

vim /usr/local/nexus/bin/nexus.rc

#打开注释，修改运行时用户为root
run_as_user="root"

4、启动

• 启动

cd /usr/local/nexus/bin/

./nexus start

• 开机自启

chmod +x /etc/rc.d/rc.local
echo "/usr/local/nexus/bin/nexus start" >> /etc/rc.d/rc.local

5、访问Nexus

http://ip:8081，默认用户admin，密码保存在/usr/local/sonatype-work/nexus3/admin.password文件中。初次登录可以修改
