Redis卸载后仍持续占用6379端口问题
我对Redis的安装感到困惑，已尝试按照各类教程及手动方式卸载Redis，但Redis仍持续占用6379端口。
dna@dna:~$ sudo netstat -tulnp | grep 6379 [sudo] password for dna: tcp 0 0 0.0.0.0:6379 0.0.0.0:* LISTEN 22141/redis-server tcp6 0 0 :::6379 :::* LISTEN 22141/redis-server dna@dna:~$ apt-get autopurge redis-server E: Could not open lock file /var/lib/dpkg/lock-frontend - open (13: Permission denied) E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), are you root? dna@dna:~$ sudo apt-get autopurge redis-server Reading package lists...

我使用Redis的Docker应用已停止，Redis镜像也已删除。以下是我的操作系统信息：

尝试通过Snap卸载Redis：
dna@dna:~$ sudo snap remove redis.server [sudo] password for dna: snap "redis.server" is not installed dna@dna:~$ sudo snap remove redis-525 snap "redis-525" is not installed dna@dna:~$ sudo netstat -tulnp | grep 6379 tcp 0 0 0.0.0.0:6379 0.0.0.0:* LISTEN 36248/redis-server tcp6 0 0 :::6379 :::* LISTEN 36248/redis-server dna@dna:~$ sudo snap remove redis.server ; sudo snap remove redis-525 snap "redis.server" is not installed snap "redis-525" is not installed dna@dna:~$ systemctl | grep -i redis run-snapd-ns-redis.mnt.mount loaded active mounted /run/snapd/ns/redis.mnt snap-redis-525.mount loaded active mounted Mount unit for redis, revision 525 snap.redis.server.service loaded active running Service for snap application redis.server dna@dna:~$ pkill -9 36248 dna@dna:~$ systemctl | grep -i redis run-snapd-ns-redis.mnt.mount loaded active mounted /run/snapd/ns/redis.mnt snap-redis-525.mount loaded active mounted Mount unit for redis, revision 525 snap.redis.server.service loaded active running Service for snap application redis.server dna@dna:~$ sudo netstat -tulnp | grep 6379 tcp 0 0 0.0.0.0:6379 0.0.0.0:* LISTEN 36248/redis-server tcp6 0 0 :::6379 :::* LISTEN 36248/redis-server dna@dna:~$
