Ubuntu制作系统服务时服务程序需要root权限

1、简单service

start_service.service

[Unit]
Description=MonitorIP
After=network-online.target
Wants=network-online.target

[Service]
WorkingDirectory=/home/up/docker-compose-test/test_demo/service_test
ExecStart=/home/up/docker-compose-test/test_demo/service_test/start.sh
Type=simple
Restart=always
TimeoutSec=infinity
User=root

[Install]
WantedBy=multi-user.target

2、服务程序需要root权限

方案一（推荐）

• 设置service文件中User为root

方案二（不推荐）

• 设置service文件中User当前用户（非root）

  [Unit]
  Description=MonitorIP
  After=network-online.target
  Wants=network-online.target
  
  [Service]
  WorkingDirectory=/home/up/docker-compose-test/test_demo/service_test
  ExecStart=/home/up/docker-compose-test/test_demo/service_test/start.sh
  Type=simple
  Restart=always
  TimeoutSec=infinity
  User=up
  
  [Install]
  WantedBy=multi-user.target
  

• 修改sudo时不需要输入密码

  • sudo vim /etc/sudoers

    在sudo下一行添加your_username ALL = (ALL) NOPASSWORD: ALL

    #
    # This file MUST be edited with the ‘visudo‘ command as root.
    #
    # Please consider adding local content in /etc/sudoers.d/ instead of
    # directly modifying this file.
    #
    # See the man page for details on how to write a sudoers file.
    #
    Defaults        env_reset
    Defaults        mail_badpass
    Defaults        secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin"
    
    # Host alias specification
    
    # User alias specification
    
    # Cmnd alias specification
    
    # User privilege specification
    root    ALL=(ALL:ALL) ALL
    
    # Members of the admin group may gain root privileges
    %admin ALL=(ALL) ALL
    
    # Allow members of group sudo to execute any command
    %sudo   ALL=(ALL:ALL) ALL
    up ALL=(ALL) NOPASSWD: ALL    # 例如这里添加up用户不输入密码
    # See sudoers(5) for more information on "#include" directives:
    
    #includedir /etc/sudoers.d
