olay: acil olarak server , lokasyon ve ip degistirmek gerekti.<\/p>\n
durum: eski serverda calisan pek cok domain, web , mail var – aktarim kolay – ancak kisa surede yeni serverda yeni ipde devam etmek istiyoruz<\/p>\n
normal prosedur : eski serverdaki servisleri durdur. Yedek al – Yedekleri yeni servera aktar – yukle – calistigindan emin olunca nameserver iplerini degistir yeni server ipleri ile – bekle – 24 saat icinde hersey yoluna girer<\/p>\n
sorun: vakit dar – tum islemin 2 3 saat icinde olmasi gerek – ancak yedekleme tek basina 10 saat suruyor –<\/p>\n
10 saat yedekle – yedekleri aktar – 50GB \ud83d\ude42 – yukle – calistir et – 12 saat oldu . bizim 2 – 3 saatimiz var<\/p>\n
dnsler degisti ancak guncellenene kadar hersey eski iplerde resolve ediyor. basa bela durumu…<\/p>\n
cozum: rinetd !<\/p>\n
rinetd redirects TCP connections from one IP address and port to another, with basic IP-based access control.rinetd is a single-process server which handles any number of connections to the address\/port pairs specified in the file \/etc\/rinetd.conf. Since rinetd runs as a single process using nonblocking I\/O, it is able to redirect a large number of connections without a severe impact on the machine. This makes it practical to run services on machines inside an IP masquerading firewall.<\/p>\n
install rinetd in ubuntu<\/p>\n
apt-get install rinetd<\/p>\n
install rinetd in centos<\/p>\n

wget http:\/\/www.boutell.com\/rinetd\/http\/rinetd.tar.gz<\/p>\n
tar zxvf rinetd.tar.gz , cd rinetd\u00a0 , make install<\/p>\n
config dosyasi yapisi cok kolay<\/p>\n

# logging information # uncomment the following line if you want web-server style logfile format rinetd example<\/strong> You\u2019ve already updated DNS to point visitors to the new IP address, but you want to ensure that people connecting to the old IP still continue to receive service.<\/p>\n To handle this example you should update the \/etc\/rinetd.conf file to read:<\/p>\n # bindadress bindport connectaddress connectport Once you restart rinetd all incoming connections on port 80 and 443 will be seamlessly redirected from the old IP to the new one – although you will need to restart rinetd after making the change to your configuration file.<\/p>\n sonre restart et inetd yi oldu bitti..<\/p>\n sitesi burada<\/p>\n
