Linux开启或关闭服务问题

下面以sshd服务举例，解释新system进程

1. systemctl start sshd(开启服务)
2. systemctl stop sshd(关闭服务)
3. systemctl restart sshd(重启服务)
4. systemctl reload sshd(重新加载配置文件，不重启服务)

---

5. systemctl enable sshd(设置服务开机自启)
6. systemctl disable sshd(禁止服务开机自启)

---

7. systemctl is-enabled sshd(查看服务是否开机自启)

8. systemctl status sshd(查看服务当前状态)
