为什么我的postgres进程仍在运行？

Question

I used 'sudo apt-get autoremove postgres' to uninstall the postgresql database on my local server. and I used 'sudo netstat -anpt' to find the the postgres is still there and is running? Why? Anybody to correct my understanding?

Answer 1

you can try a manual uninstallation (as root, assuming a default installation path):

/opt/PostgreSQL/8.3/installer/server/removeshortcuts.sh /opt/PostgreSQL/8.3 8.3
/etc/init.d postgresql-8.3 stop
rm -rf /opt/PostgreSQL
rm /etc/postgres-reg.ini
rm -rf /etc/init.d/postgresql-8.3
userdel postgres

if /etc/ld.so.conf exists, edit it and remove /opt/PostgreSQL/8.3/lib
if present.

if /etc/ld.so.conf.d exists:

rm /etc/ld.so.conf.d/postgresql-8.3.conf

It's because a running process is in memory so it's independent of what's happening on the disk. It only matters if the running process needs to load something that's been removed. All you need to do is find the process id ( ps -aux ) then kill -9 <pid> .
