安裝Nexus Repository

1. 安裝wget & java

yum install wget -y
yum install -y java-1.8.0-openjdk.x86_64

2. 下載nexus並解壓縮

wget -O nexus.tar.gz https://download.sonatype.com/nexus/3/latest-unix.tar.gz
tar -xvf nexus.tar.gz -C /opt
mv /opt/nexus-3* /opt/nexus

3. 建立使用者nexus

sudo adduser nexus
sudo chown -R nexus:nexus /opt/nexus
sudo chown -R nexus:nexus /opt/sonatype-work

4. 修改檔案

vi /opt/nexus/bin/nexus.rc

run_as_user="nexus"

vi /etc/security/limits.conf

nexus - nofile 65536

以下依情況調整

vi /opt/nexus/bin/nexus.vmoptions

5. 設定nexus服務

vi /etc/systemd/system/nexus.service

[Unit]

sudo systemctl enable nexus
sudo systemctl start nexus
