Proper way to change server hostname

[myVesta]

In your SSH, as root, run:

Code: Select all

OLDHOST=''  # enter here old hostname
OLDNS1=''   # enter here old NS1
OLDNS2=''   # enter here old NS2

NEWHOST=''  # enter here new hostname
NEWNS1=''   # enter here new NS1
NEWNS2=''   # enter here new NS2

/usr/local/vesta/bin/v-change-sys-hostname "$NEWHOST"

find /home/*/conf/dns/ -type f -exec sed -i "s#$OLDHOST#$NEWHOST#g" {} \;
find /home/*/conf/dns/ -type f -exec sed -i "s#$OLDNS1#$NEWNS1#g" {} \;
find /home/*/conf/dns/ -type f -exec sed -i "s#$OLDNS2#$NEWNS2#g" {} \;
find /usr/local/vesta/data/users/*/dns/ -type f -exec sed -i "s#$OLDHOST#$NEWHOST#g" {} \;
find /usr/local/vesta/data/users/*/dns/ -type f -exec sed -i "s#$OLDNS1#$NEWNS1#g" {} \;
find /usr/local/vesta/data/users/*/dns/ -type f -exec sed -i "s#$OLDNS2#$NEWNS2#g" {} \;
sed -i "s#$OLDHOST#$NEWHOST#g" /usr/local/vesta/data/users/*/dns.conf
sed -i "s#$OLDNS1#$NEWNS1#g" /usr/local/vesta/data/users/*/dns.conf
sed -i "s#$OLDHOST#$NEWHOST#g" /usr/local/vesta/data/users/*/user.conf
sed -i "s#$OLDNS1#$NEWNS1#g" /usr/local/vesta/data/users/*/user.conf
sed -i "s#$OLDNS2#$NEWNS2#g" /usr/local/vesta/data/users/*/user.conf
sed -i "s/$OLDHOST/$NEWHOST/g" /etc/roundcube/plugins/password/config.inc.php
grep -rl "$OLDHOST" /etc | xargs sed -i "s/$OLDHOST/$NEWHOST/g"
grep -rl "$OLDHOST" /usr/local/vesta/conf | xargs sed -i "s/$OLDHOST/$NEWHOST/g"
sed -i "s#$OLDNS1#$NEWNS1#g" /usr/local/vesta/data/packages/*.pkg
sed -i "s#$OLDNS2#$NEWNS2#g" /usr/local/vesta/data/packages/*.pkg
service bind9 reload

Hey dpeca,

there's a little typo in your command, it should be /local/ and not loal.

However, this is the error I got when I executed it

Code: Select all

root@s628141:~# /usr/local/vesta/bin/v-change-sys-hostname MYNEWHOSTNAME
/usr/local/vesta/bin/v-change-sys-hostname: line 16: /func/main.sh: No such file or directory
/usr/local/vesta/bin/v-change-sys-hostname: line 17: /conf/vesta.conf: No such file or directory
/usr/local/vesta/bin/v-change-sys-hostname: line 24: check_args: command not found
/usr/local/vesta/bin/v-change-sys-hostname: line 25: is_format_valid: command not found
/usr/local/vesta/bin/v-change-sys-hostname: line 53: log_event: command not found

Tnx for typo

Thanks, adding that to env worked.

But now I got this. I tried making a bash file as well as pasting it directly in terminal.
Same error in both cases

Code: Select all

root@janus:~# grep -rl "$OLDHOST" /etc | xargs sed -i "s/$OLDHOST/$NEWHOST/g"
sed: no input files
root@janus:~# grep -rl "$OLDHOST" /usr/local/vesta/conf | xargs sed -i "s/$OLDHOST/$NEWHOST/g"
sed: no input files

That's ok, grep found nothing and just printed that warning.
Actually, sed got empty list of files from grep...

Alright. Perfect then.

I've got some number of domains associated with my server. Is it right to change server hostname to IP address? I guess, this one bring me some errors (such as ssl cert applied to one domain, but from the another one)/
