折腾:
【已解决】CentOS中如何用systemctl管理supervisor包括设置supervisor开机启动
搜到了:
How To Use Systemctl to Manage Systemd Services and Units | DigitalOcean
之前是已经知道了基本用法:
<code>systemctl status xxx systemctl start xxx systemctl stop xxx systemctl restart xxx systemctl reload xxx systemctl enable xxx systemctl disable xxx systemctl is-enabled xxx systemctl is-active xxx </code>
但是更高级的,不知道,所以继续去学习学习,和systemctl有关的东西:
systemctl cat
<code>[root@xx-general-01 robotDemo]# systemctl cat supervisord # /usr/lib/systemd/system/supervisord.service [Unit] Description=Process Monitoring and Control Daemon After=rc-local.service nss-user-lookup.target [Service] Type=forking ExecStart=/usr/bin/supervisord -c /etc/supervisord.conf [Install] WantedBy=multi-user.target [root@xx-general-01 robotDemo]# ll /usr/lib/systemd/system/supervisord.service -rw-r--r-- 1 root root 221 Jul 29 2017 /usr/lib/systemd/system/supervisord.service </code>
看看list-dependencies:
<code>[root@xx-general-01 robotDemo]# systemctl list-dependencies supervisord supervisord.service ● ├─system.slice ● └─basic.target ● ├─microcode.service ● ├─rhel-autorelabel-mark.service ● ├─rhel-autorelabel.service ● ├─rhel-configure.service ● ├─rhel-dmesg.service ● ├─rhel-loadmodules.service ● ├─selinux-policy-migrate-local-changes@targeted.service ● ├─paths.target ● ├─slices.target ● │ ├─-.slice ● │ └─system.slice ● ├─sockets.target ● │ ├─dbus.socket ● │ ├─systemd-initctl.socket ● │ ├─systemd-journald.socket ● │ ├─systemd-shutdownd.socket ● │ ├─systemd-udevd-control.socket ● │ └─systemd-udevd-kernel.socket ● ├─sysinit.target ● │ ├─dev-hugepages.mount ● │ ├─dev-mqueue.mount ● │ ├─kmod-static-nodes.service ● │ ├─plymouth-read-write.service ● │ ├─plymouth-start.service ● │ ├─proc-sys-fs-binfmt_misc.automount ● │ ├─sys-fs-fuse-connections.mount ● │ ├─sys-kernel-config.mount ● │ ├─sys-kernel-debug.mount ● │ ├─systemd-ask-password-console.path ● │ ├─systemd-binfmt.service ● │ ├─systemd-firstboot.service ● │ ├─systemd-hwdb-update.service ● │ ├─systemd-journal-catalog-update.service ● │ ├─systemd-journal-flush.service ● │ ├─systemd-journald.service ● │ ├─systemd-machine-id-commit.service ● │ ├─systemd-modules-load.service ● │ ├─systemd-random-seed.service ● │ ├─systemd-sysctl.service ● │ ├─systemd-tmpfiles-setup-dev.service ● │ ├─systemd-tmpfiles-setup.service ● │ ├─systemd-udev-trigger.service ● │ ├─systemd-udevd.service ● │ ├─systemd-update-done.service ● │ ├─systemd-update-utmp.service ● │ ├─systemd-vconsole-setup.service ● │ ├─cryptsetup.target ● │ ├─local-fs.target ● │ │ ├─-.mount ● │ │ ├─rhel-import-state.service ● │ │ ├─rhel-readonly.service ● │ │ ├─systemd-fsck-root.service ● │ │ └─systemd-remount-fs.service ● │ └─swap.target ● └─timers.target ● └─systemd-tmpfiles-clean.timer [root@xx-general-01 robotDemo]# </code>
再去看看show:

有机会,去试试:
mask
unmask
和systemctl相关的:
systemctl
daemons进程:systemd
管理系统的进程和服务
journalctl
daemons进程:journald
管理日志log management
loginctl
