一、開機啟動服務的配置
1.創建服務配置(權限754)
vim /usr/lib/systemd/system/nginx.service
文件內容解釋
[Unit]:服務的說明
Description:描述服務
After:描述服務類別
[Service]服務運行參數的設置
Type=forking是后台運行的形式
ExecStart為服務的具體運行命令
ExecReload為重啟命令
ExecStop為停止命令
PrivateTmp=True表示給服務分配獨立的臨時空間
注意：啟動、重啟、停止命令全部要求使用絕對路徑
[Install]服務安裝的相關設置，可設置為多用戶
以754的權限保存服務配置！！！
2.設置開機自啟動
任意目錄下執行::systemctl enable nginx.service
二、開機啟動服務的管理
- 啟動nginx服務 systemctl start nginx.service
- 設置開機自啟動 systemctl enable nginx.service
- 停止開機自啟動 systemctl disable nginx.service
- 查看服務當前狀態 systemctl status nginx.service
- 重新啟動服務 systemctl restart nginx.service
- 查看所有已啟動的服務 systemctl list-units --type=service
