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
