我在启动 dovecot 服务器时遇到了一些问题。我收到以下错误：
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
因此我netstat针对 993 端口运行命令：
# 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
我该怎么做才能停止 init 进程监听这些端口？
编辑
命令结果systemctl -all list-sockets：
# systemctl -all list-sockets

答案1
尝试停止套接字并重新启动dovecot。
systemctl stop dovecot.socket
systemctl start dovecot.service
看起来套接字在启动dovecot之前就已经启动了dovecot。
