chkconfig sshd –list ==> ls /etc/systemd/system/*.wants/sshd.service
查看服务是否开机自启:
systemctl is-enabled name.service
查看服务的依赖关系:
systemctl list-dependencies name.service
杀掉进程:
systemctl kill unitname
[](()3.服务状态
systemctl list-unit-files –type service –all显示状态
loaded Unit配置文件已处理
active(running) 一次或多次持续处理的运行
active(exited) 成功完成一次性的配置
active(waiting) 运行中,等待一个事件
inactive 不运行
enabled 开机启动
disabled 开机不启动
static 开机不启动,但可被另一个启用的服务激活
[](()4.例子
显示所有单元状态
systemctl 或 systemctl list-units
只显示服务单元的状态
systemctl –type=service
显示sshd服务单元
systemctl –l status sshd.service
验证sshd服务当前是否活动
systemctl is-active sshd
启动,停止和重启sshd服务
systemctl start sshd.service
systemctl stop sshd.service
systemctl restart sshd.service
重新加载配置
systemctl reload sshd.service
列出活动状态的所有服务单元
systemctl list-units –type=service
列出所有服务单元
systemctl list-units –type=service –all
查看服务单元的启用和禁用状态
systemctl list-unit-files –type=service
列出失败的服务
systemctl –failed –type=service
列出依赖的单元
systemctl list-dependencies sshd
验证sshd服务是否开机启动
systemctl is-enabled sshd
禁用network,使之不能自动启动,但手动可以
systemctl disable network
启用network
systemctl enable network
禁用network,使之不能手动或自动启动
systemctl mask network
启用network
systemctl unmask network
