Automatic creation of users/passwords (FTP)
Manually create list.txt with user:doc_root
e.g.:
mydomain.com:/var/www/vhost/mydomain.com
example.com:/var/www/vhost/example.com
Get commands to create FTP users
cat list.txt | awk -F: '{print "useradd -d ",$2, "-s /bin/false -c TICKET_NUMBER ",$1 }'
Get commands to set FTP permissions (if doc_root exists already)
cat list.txt | awk -F: '{print "chown -R",$1, $2 }'
Generate and Assign random passwords to the users.
# for USER in $(awk -F: '{print $1}' list.txt) ; do PASS=$(tr -cd '[:alnum:]' < /dev/urandom | fold -w12 | head -n1) ; echo $PASS | passwd --stdin $USER ; echo -e "username: $USER\npassword: $PASS\n" | tee -a pass.txt ; done ; echo -e "\n========================\nHere the credentials:" ; cat pass.txt
Create a list of vhosts’ paths: vhosts.txt
Example with only .com domains:
/var/www/domain1.com
/var/www/domain2.com
/var/www/domain3.com
Use a regex for sed to extract the vhost name, removing dots (example based on the example above)
This will return a list of PATH and VHOSTNAME. We will use VHOSTNAME as USER for that path
for i in `cat vhosts.txt` ; do echo "$i" | tr '\n' ' ' ; echo "$i" | sed 's/^.*www\/\(.*\)com.*$/\1/' | sed 's/\.//g' ; done >> list.txt
Print out the commands to run to add FTP users (no SSH)
Once checked the output, run these lines
cat list.txt | awk '{print "useradd -d ",$1, "-s /bin/false -c COMMENT_HERE ",$2 }'
(for sftp only):
cat list.txt | awk '{print "useradd -d ",$1, "-s /bin/false -G sftponly -cCOMMENT_HERE ",$2 }'
This will print out commands to run to assign user:apache_group to the vhosts’ paths
cat list.txt | awk '{print "chown -R ",$2 ":www-data ",$1 }'
(for sftp only):
cat list.txt | awk '{print "chown root:root",$1 }'
cat list.txt | awk '{print "chown -R ",$2":"$2 ,$1"/*"}'
Set g+s on vhosts to preserve directory owner
[TO CHECK]
for i in `cat list.txt` ; do echo "chmod g+s $i" ; done
[THIS EXECUTE]
for i in `cat list.txt` ; do chmod g+s "$i" ; done
Create list of random passwords using pwgen
for i in `cat list.txt` ; do p=$(pwgen -s -B 16 1) ; echo "$i:$p" ; done > list_u_p.txt
Create list of random passwords using openssl
for i in `cat list.txt` ; do p=$(openssl rand -base64 12) ; echo "$i:$p" ; done > list_u_p.txt
Apply these passwords automatically
for i in `cat list_u_p.txt` ; do USER=`echo "$i" | awk -F":" '{print $1}'` ; PASS=`echo "$i" | awk -F":" '{print $2}'` ; echo -e "$PASS\n$PASS" | passwd "$USER" ; done
Print output for reference
hostname ; cat list_u_p.txt | awk -F":" '{print "\nusername:", $1, "\npassword:", $2}'
