Hướng dẫn đổi ip chính cho VestaCP

Hôm nay mình hướng dẫn các bạn cách thay đổi ip chính trên VestaCP.
Bước 1: Bạn thực hiện tạo file , phân quyền và dán đoạn mã sau

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

Dán đoạn code bên dưới vào file:

#!/bin/sh
#script to change ips on a VestaCP server.
#usage:
# $0 <oldip> <newip>
LOG=/var/log/vesta/system.log
MYUID=`/usr/bin/id -u`
if [ "$MYUID" != 0 ]; then
        echo "You require Root Access to run this script";
        exit 0;
fi
if [ $# != 2 ] && [ $# != 3 ]; then
        echo "Usage:";
        echo "$0 <oldip> <newip> [<file>]";
        echo "you gave #$#: $0 $1 $2 $3";
        exit 0;
fi

HAVE_HTTPD=1
HAVE_NGINX=1
DATE=`date '+%F %X'`
BIN=`echo $0 | awk -F/ '{print $NF}'`
log()
{
        echo -e "$1";
        echo -e "$1" >> $LOG;
}
swapfile()
{
        if [ ! -e $1 ]; then
                log "Cannot Find $1 to change the IPs. Skipping...";
                return;

        read YESNO;
        if [ "$YESNO" != "y" ]; then
                exit 0;
        fi
else
        mv -f $IPFILE_OLD $IPFILE_NEW
        log "$DATE $0 $IPFILE_OLD\t: $OLD_IP -> $NEW_IP";

if [ "${HAVE_HTTPD}" -eq 1 ]; then
        if [ -e /etc/httpd/conf.d/${OLD_IP}.conf ]; then
                swapfile /etc/httpd/conf.d/${OLD_IP}.conf

for i in `ls $ULDDU`; do

                continue;

        swapfile $ULDDU/$i/dns.conf
        for j in `ls $ULDDU/$i/dns/*.conf`; do
        {
                swapfile $j
        };
        done;

#this is needed to update the serial in the db files.
if [ "${HAVE_HTTPD}" -eq 1 ]; then
   service httpd restart
fi

   service nginx restart
fi
echo "*** Done swapping $OLD_IP to $NEW_IP ***";

Bước 2: Chạy lệnh sau để thực thi

 v-change-server-ip 103.x.x.1 103.x.x.2

• trong đó “103.x.x.1 là IP cũ” và “103.x.x.2 là IP mới cần thay đổi”

Chúc bạn thực hiện thành công!
