nexus2設定開機自啟

想把整套環境，所有的服務都在伺服器上搭一遍，但是有時家裡會跳閘，服務就會停掉，所以安裝了一下開啟自啟。
指令碼檔案：
cat > /lib/systemd/system/nexus.service <<-EOF [Unit] Description=nexus After=network.target [Service] Type=forking Environment=RUN_AS_USER=root Environment=PATH=/root/.tiup/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/usr/lib/jvm/java-1.8.0-openjdk/bin:/wgr/maven/apache-maven-3.6.2/bin:/root/bin:/usr/lib/jvm/java-1.8.0-openjdk/bin:/wgr/maven/apache-maven-3.6.2/bin:/usr/lib/jvm/java-1.8.0-openjdk/bin:/wgr/maven/apache-maven-3.6.2/bin ExecStart=/wgr/nexus-2.14.15-01/bin/nexus start ExecReload=/wgr/nexus-2.14.15-01/bin/nexus restart ExecStop=/wgr/nexus-2.14.15-01/bin/nexus stop PrivateTmp=true [Install] WantedBy=multi-user.target EOF
