How to Auto Change IP Address in VestaCP

[jobarte]

Hi @crypto,

You have this code on github? I want to help you wtih bug fixes. If not, I can put on github?

Hello

I have completed the instruction. Ip has been successfully changed.
But now problem. Site is not open: 504 Gateway Time-out (nginx).

nginx log:
[error] 11506#0: *7 upstream timed out (110: Connection timed out) while connecting to upstream, client: 178.76.231.212, server: _, request: "GET /favicon.ico HTTP/1.1", upstream: "http://10.73.117.115:8080/error/50x.html", host: "54.74.17.21", referrer: "http://54.74.87.18/"

178.76.231.212 - it is my ip
10.73.117.115 - it is new private ip, it used in instruction
54.74.17.21 - it is new public ip, I was set this ip as NAT ip in control panel

How fix it?

hi, i have the same issue... i get:

2015/12/01 22:36:14 [error] 3075#0: *1 connect() failed (111: Connection refused) while connecting to upstream, client: MYIP, server: domainame.com, request: "GET /favicon.ico HTTP/1.1", upstream: "http://SERVERIP2:8080/favicon.ico", host: "DOMAINAME.COM", referrer: "http://DOMAINNAME.COM/"

any idea what could this be?

[psaproxy]

my solution
xx.xx.xx.xx - old private IP
yy.yy.yy.yy - new private IP

1) run instruction from first post

2)
grep -r "xx.xx.xx.xx" /etc/
grep -r "xx.xx.xx.xx" /home/
grep -r "xx.xx.xx.xx" /usr/local/
and replace all "xx.xx.xx.xx"/"xx-xx-xx-xx" on "yy.yy.yy.yy"/"yy-yy-yy-yy"

3)
rename files
/etc/apache2/conf.d/xx.xx.xx.xx.conf in yy.yy.yy.yy.conf
/etc/nginx/conf.d/xx.xx.xx.xx.conf in yy.yy.yy.yy.conf

4)
set new public IP in NAT Vesta control panel

5)
restart server

And may be you need change public IP on WEB and DNS sections in Vesta control panel

[kaines]

in my case i had to do this:

/etc/apache2/conf.d - rename OLDIP.conf to NEWIP.conf than edit NEWIP.conf and ranem old ip to new one.
/etc/iptables.rules - change this line: -A INPUT -s OLDIP/32 -j ACCEPT -> -A INPUT -s NEWIP/32 -j ACCEPT

after that i restarted apache and nginx and everything worked well.

Hope it will help someone ;)

[conneXions]

I think psaproxy's post above is quite helpful
though that NAT step may not apply for everyone (not for me anyway).

an additional step that finally got everything working (before this only vestacp is accessable using domain.com:8083) for me is:

restart iptables from within the server tab of vestacp (or use command line I suppose)

otherwise I couldn't even get my homepage (domain.com) to load.

Hello,

I have amended crypto's original script from post #1.

It now contains a switch to be verbose or not.

It also has some checks for empty directories, as the original script gave errors when my dns folder was empty, so it now checks for this.

Some users like myself use apache2 and not httpd, and as such the configuration options may need to changed to reflect this.

very useful. thanks

one should easily be able to search and replace either for filenames or for content of files with two commands...
not a lot of magic after all, did this multiple times on standard debian installs - but do use at your own risk!

Code: Select all

find /home /etc /usr -type f -exec perl -i -p -e 's/11\.22\.33\.44/66\.77\.88\.99/g' {} \;
find / -name *11.22.33.44* -exec rename 's/11\.22\.33\.44/66\.77\.88\.99/g' {} \;

- 11.22.33.44 has to be replaced by your old ip and 66.77.88.99 by your new one
- you need to keep the . escaped properly as shown above
- don't do this on /var if you don't exactly know what you are doing. at least mysql doesn't like that kind of find and replace with its files.

as there is not much output at all, you might want to find/grep for your IP as names/in files beforehand, to see whats gonna be changed.
and of course don't forget to restart your services afterwards (including vesta).

Option 1 didnt wrk .
i worked with option 2 and it works.
Thanks for the great script :)

In case you change vps's/ips and need to change the Shared Ip for your vestacp server, can be a real pain to do by hand.

Option 1 - Best Way Download and Run Code

Code: Select all

wget http://www.nobill.tv/dl/changeip.tar.gz
tar -zxvf changeip.tar.gz
mv v-change-server-ip /usr/local/vesta/bin/
v-change-server-ip OLDIP NEWIP

Option 2 - Long way Create it yourself

Code: Select all

touch /usr/local/vesta/bin/v-change-server-ip
chmod 0755 /usr/local/vesta/bin/v-change-server-ip

Code: Select all
