* systemctl stop rpcbind
* systemd 在系统启动时使用了并发的启动机制，而旧版本使用 init， 按顺序依次启动每项服务
* systemd 按需启动服务，服务被请求时会启动，使用完成后会动态将该服务关闭
* systemd 核心的概念：单元（unit）和 目标（target）
** systemd 进程对系统的管理就是通过一个个的单元来实现的。比如服务，每一个服务都有一个对应的单元，而且每个单元都有一个配置文件，配置文件通常以 .service 作为文件名后缀，像 sshd 服务，它的配置文件就是 /usr/lib/systemd/system/sshd.service
** 目标单元（target unit），或者简称目标（target），它们的配置文件名后缀为 .target。在 systemd 中，target 用来模拟实现系统不同的运行级别

系统初始化进程 systemd

  • systemd 在系统启动时使用了并发的启动机制，而旧版本使用 init， 按顺序依次启动每项服务
  • systemd 按需启动服务，服务被请求时会启动，使用完成后会动态将该服务关闭
  • systemd 核心的概念：单元（unit）和 目标（target）
    • systemd 进程对系统的管理就是通过一个个的单元来实现的。比如服务，每一个服务都有一个对应的单元，而且每个单元都有一个配置文件，配置文件通常以 .service 作为文件名后缀，像 sshd 服务，它的配置文件就是 /usr/lib/systemd/system/sshd.service
    • 目标单元（target unit），或者简称目标（target），它们的配置文件名后缀为 .target。在 systemd 中，target 用来模拟实现系统不同的运行级别

常用的运行级别

  • 3 多用户字符模式，multi-user.target
