Deleting temporary directories from weblogic server - unix

Before starting weblogic server I want to delete temporary directories that weblogic creates, I see below directories in my Admin Server:
path: user_projects/domains/my_domain/servers/AdminServer
cache
sysman
adr
data
logs
tmp
and below for my Managed Server:
path: user_projects/domains/my_domain/servers/MyManagedServer
cache
data
logs
stage
tmp
I have installed my WLS 10.3.6 in production mode on my Linux box, what all directories I can delete? Also I read that deleting some files here will make WLS to re-deploy the applications once again, is that true?
I am new to using weblogic so confused on if I delete any files will cause any issues.

As G. Demecki mentions, do not delete the data directory on the admin server as you will lose the embedded LDAP that weblogic uses for the DefaultAuthenticator.
tmp and cache directories are fine to remove, do it when the server is not running.

You can delete tmp, cache safely, but do not delete log, if you don't want log folder just take a back up or rename the folder[mv log log.bkp.date] and then delete the original log folder. Sometimes if the server stops running as admin you have to check the log files, or provide log files if any one asks in your work environment.

Try to delete .DAT and .LOK files with this code:
rm -f /home/Oracle/Middleware/user_projects/domains/bifoundation_domain/servers/bi_server1/tmp/bi_server1.lok
rm -f /home/Oracle/Middleware/user_projects/domains/bifoundation_domain/servers/bi_server1/data/ldap/ldapfiles/EmbeddedLDAP.lok
rm -f /home/Oracle/Middleware/user_projects/domains/bifoundation_domain/servers/AdminServer/data/ldap/ldapfiles/EmbeddedLDAP.lok
rm -f /home/Oracle/Middleware/user_projects/domains/bifoundation_domain/servers/bi_server1/data/store/default/_WS_BI_SERVER1000000.DAT
rm -f /home/Oracle/Middleware/user_projects/domains/bifoundation_domain/servers/bi_server1/data/store/diagnostics/WLS_DIAGNOSTICS000000.DAT
rm -f /home/Oracle/Middleware/user_projects/domains/bifoundation_domain/servers/AdminServer/data/store/default/_WLS_ADMINSERVER000000.DAT
rm -f /home/Oracle/Middleware/user_projects/domains/bifoundation_domain/servers/AdminServer/data/store/diagnostics/WLS_DIAGNOSTICS000000.DAT
rm -f /home/Oracle/Middleware/user_projects/domains/bifoundation_domain/servers/AdminServer/tmp/AdminServer.lok

The cache directory only needs to delete these two directories.
cache
tmp

Cannot delete files on AWS EC2 via FTP, permission denied

I run a WordPress site on AWS EC2 with Litespeed.
When I log in via FTP I cannot delete anything, neither plugin nor theme files. FileZilla shows a rm /path/to/file permission denied error:
These are due to permissions issue, as you are trying to delete the files while loggged in from user that is not the owner of those files.That www-data is server user, ask your server provider to remove those files or change the owner of files.
For this issue, you need to change the owner of the files.
This command will work for you
sudo chown -R www-data:www-data /var/www/html
Run this command from your ssh and try again.

Not able to mount directory after updating fstab

On a Windows file share I created a folder and shared it with a service account.
I have added a mount point entry to fstab like this:
//server/folder /mnt/folder cifs credentials=/root/creds/creds,noperm
Where the creds file contains credentials for above mentioned service account.
Then run mount -a to activate the mount point.
It gives an error like:
mount error(2): No such file or directory
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
Couldn't chdir to /mnt/folder: No such file or directory
I have tried mounting the directory manually and receive the same error.
What the heck am I missing?
Ah. I had not created folder in /mnt/folder on the UNIX side. Did mkdir /mnt/folder.
I was then able to see folder in /mnt but it was empty.
Did a mount -a and can now see the contents of the Windows share in /mnt/folder
I seems like I had to do mount -a from /etc as when I issued the command from /mnt it just hung for a while until I killed it and then tried from /etc

How do I remove a file in my root directory?

I tried to create a directory /data as a mount point but that failed for other reasons, now I've got a weird file/data thing in my root directory that just won't die:
user#PC:~$ sudo ls /data
ls: cannot access /data: Transport endpoint is not connected
user#PC:~$ sudo rm -rf /data
rm: cannot remove ‘/data’: Is a directory
I initially created it using mkdir but if I browse to the file in ubuntu it looks like a file in the file browser. How do I get rid of this thing?
First try unmounting then you should be able to delete it.
Then if that fails, and this is going to sound like a Windows solution but it might work, try rebooting and doing unmount/remount delete again.

rsync folder from local system to server does not work

I'm trying to copy my webfolder 'depot' from my local machine to my server on Digital Ocean.
For that I run this command in the terminal:
rsync -anv ./Sites/depot root#my-server-ip:/sites
But when I ssh into my server and cd into the sites folder, the 'depot' folder is not there.
Am I doing something wrong?
You have set the -n flag, which results in a "dry run" (you get to see which files would be copied/deleted without actually doing any damage).
To do the actual copy you need to omit the -n flag:
rsync -av ./Sites/depot root#my-server-ip:/sites/depot
Also be careful about how you specify paths for rsync - normally you need a trailing /:
rsync -av ./Sites/depot/ root#my-server-ip:/sites/depot/
otherwise you can end up with copies of directories inside of directories (e.g. sites/depot/depot).
See man rsync for full details.

How to change the owner for a rsync

I understand preserving the permissions for rsync.
However in my case my local computer does not have the user the files need to under for the webserver. So when I rsync I need the owner and group to be apache on the webserver, but be my username on my local computer. Any suggestions?
I wanted to clarify to explain exactly what I need done.
My personal computer: named 'home' with the user account 'michael'
My web server: named 'server' with the user account 'remote' and user account 'apache'
Current situation: My website is on 'home' with the owner 'michael' and on 'server' with the owner 'apache'. 'home' needs to be using the user 'michael' and 'server' needs to be using the user 'apache'
Task: rsync my website on 'home' to 'server' but have all the files owner by 'apache' and the group 'apache'
Problem: rsync will preseve the permissions, owner, and group; however, I need all the files to be owner by apache. I know the not preserving the owner will put the owner of the user on 'server' but since that user is 'remote' then it uses that instead of 'apache'. I can not rsync with the user 'apache' (which would be nice), but a security risk I'm not willing to open up.
My only idea on how to solve: after each rsync manually chown -R and chgrp -R, but it's a huge system and this takes a long time, especially since this is going to production.
Does anyone know how to do this?
Current command I use to rsync:
rsync --progress -rltpDzC --force --delete -e "ssh -p22" ./ remote#server.com:/website
If you have access to rsync v.3.1.0 or later, use the --chown option:
rsync -og --chown=apache:apache [src] [dst]
More info in an answer from a similar question here: ServerFault: Rsync command issues, owner and group permissions doesn´t change
There are hacks you could put together on the receiving machine to get the ownership right -- run 'chmod -R apache /website' out of cron would be an effective but pretty kludgey option -- but instead, I'd recommend securely allowing rsync-over-ssh-as-apache.
You'd create a dedicated ssh keypair for this:
ssh-keygen -f ~/.ssh/apache-rsync
and then take ~/.ssh/apache-rsync.pub over to the webserver, where you'd put it into ~apache/.ssh/authorized_keys and carefully specify the allowed command, something like so, all on one line:
command="rsync --server -vlogDtprCz --delete . /website",from="IP.ADDR.OF.SENDER",no-port-forwarding,no-X11-forwarding,no-pty ssh-rsa AAABKEYPUBTEXTsVX9NjIK59wJ+fjDgTQtGwhATsfidQbO6u77dbAjTUmWCZjKAQ/fEFWZGSlqcO2yXXXXXXXXXXVd9DSS1tjE6vAQaRdnMXBggtn4M9rnePD2qlR5QOAUUwhyFPhm6U4VFhRoa3wLvoqCVtCV0cuirB6I45On96OPijOwvAuz3KIE3+W9offomzHsljUMXXXXXXXXXXMoYLywMG/GPrZ8supIDYk57waTQWymUyRohoQqFGMzuDNbq+U0JSRlvLFoVUZ5Piz+gKJwwiFwwAW2iNag/c4Mrb/BVDQAyEQ== comment#email.address
and then your rsync command on your "home" machine would be something like
rsync -av --delete -e 'ssh -i ~/.ssh/apache-rsync apache#server' ./ /website
There are other ways to skin this cat, but this is the clearest and involves the fewest workarounds, to my mind. It prevents getting a shell as apache, which is the biggest security concern, natch. If you're really deadset against allowing ssh as apache, there are other ways ... but this is how I've done it.

Last version (at least 3.1.1) of rsync allows you to specify the "remote ownership":
--usermap=tom:www-data
Changes tom ownership to www-data (aka PHP/Nginx). If you are using Mac as the client, use brew to upgrade to the last version. And on your server, download archives sources, then "make" it!
The solution using rsync --chown USER:GROUP [src] [dst] only works if the remote user has write access to the the destination directory which in most cases is not the case.
Here's another solution:
Overview
(srcmachine) (rsync) (destmachine)
srcuser -- SSH --> destuser
|
| sudo su jenkins
|
v
jenkins
Let's say that you want to rsync:
From:
Machine: srcmachine
User: srcuser
Directory: /var/lib/jenkins
To:
Machine: destmachine
User: destuser to establish the SSH connection.
Directory: /tmp
Final files owner: jenkins.
Solution
rsync --rsync-path 'sudo -u jenkins rsync' -avP --delete /var/lib/jenkins destuser#destmachine:/tmp

rsync version 3.1.2
I mostly use windows in local, so this is the command line i use to sync files with the server (debian) :
user#user-PC /cygdrive/c/wamp64/www/projects
$ rsync -rptgoDvhnP --chown=www-data:www-data --exclude=.env --exclude=vendor --exclude=node_modules --exclude=.git --exclude=tests --exclude=.phpintel --exclude=storage ./website/ username#hostname:/var/www/html/website
-n : perform a trial run with no changes made, to really execute the command remove the -n option
