我在启动dovecot服务器时遇到了一些问题。 我得到以下错误：
Failed to start Dovecot : Error: service(imap-login): listen(*, 143) failed: Address already in use Error: service(imap-login): listen(::, 143) failed: Address already in use Error: service(imap-login): listen(*, 993) failed: Address already in use Error: service(imap-login): listen(::, 993) failed: Address already in use Fatal: Failed to start listeners 所以我运行993端口的netstat命令：
# netstat -lnp | grep 993 tcp 0 0 0.0.0.0:993 0.0.0.0:* LISTEN 1/init tcp6 0 0 :::993 :::* LISTEN 1/init
我能做些什么来阻止init进程监听这些端口？
编辑
systemctl -all list-sockets命令的结果：
# systemctl -all list-sockets LISTEN UNIT ACTIVATES /run/acpid.socket acpid.socket acpid.service /run/dmeventd-client dm-event.socket dm-event.service /run/dmeventd-server dm-event.socket dm-event.service /run/lvm/lvmetad.socket lvm2-lvmetad.socket lvm2-lvmetad.service /run/systemd/initctl/fifo systemd-initctl.socket systemd-initctl.service /run/systemd/journal/dev-log systemd-journald-dev-log.socket systemd-journald.service /run/systemd/journal/socket systemd-journald.socket systemd-journald.service /run/systemd/journal/stdout systemd-journald.socket systemd-journald.service /run/systemd/journal/syslog syslog.socket rsyslog.service /run/systemd/shutdownd systemd-shutdownd.socket systemd-shutdownd.service /run/udev/control systemd-udevd-control.socket systemd-udevd.service /var/run/clamav/clamd.ctl clamav-daemon.socket clamav-daemon.service /var/run/dbus/system_bus_socket dbus.socket dbus.service 0.0.0.0:143 dovecot.socket dovecot.service 0.0.0.0:993 dovecot.socket dovecot.service [::]:143 dovecot.socket dovecot.service [::]:993 dovecot.socket dovecot.service kobject-uevent 1 systemd-udevd-kernel.socket systemd-udevd.service 18 sockets listed.
尝试停止套接字并重新启动dovecot 。
systemctl stop dovecot.socket systemctl start dovecot.service
看起来dovecot socket是在dovecot启动之前启动的。
