Configure the DNS server locally (Mac Edition)

As a front-end developer, will encounter cookie the use of the situation, common such as: login, rights control, video playback, graphics verification code, and so on, the local developer on the PC will use the modified hosts way to add to the local domain name, to obtain cookie the same domain name. Such as:

127.0.0.1 local.smartstudy.com 

But in the mobile side of the time, this trick is not good, Apple mobile phone in the case of no jailbreak can not be modified, is it for hosts this to let their love machine more prison? The answer should be negative. So how do we deal with this problem? The perfect solution is to configure the DNS service for the local area network. So I looked up a series of documents, summed up this article, stepped on a little pit, hope Yimeimei do not step on the repeated, because I use the Mac, so some of the following commands and the Mac party, other systems are similar, only write system commands may be different, nonsense not much to say, June and detailed look:

Installation

update; brew install dnsmasq;  

Start

sudo brew services start dnsmasq  

Restart

sudo brew services restart dnsmasq  

Stop it

stop dnsmasq  

View DNSMASQ's Run

ps aux | grep dnsmasq  

Find running parameters

/usr/local/opt/dnsmasq/sbin/dnsmasq --keep-in-foreground -C /usr/local/etc/dnsmasq.conf

Locate the Run configuration file:

/usr/local/etc/dnsmasq.conf

Edit him, here with vim:

vim /usr/local/etc/dnsmasq.conf  

Do the following things, remove the following comments, and modify, the specific configuration is what to do, there will be said later:

no-resolv  no-poll  listen-address=127.0.0.1,172.17.7.115 addn-hosts=/etc/dnsmasq.hosts 

Add custom Hosts File dnsmasq.hosts

vim /etc/dnsmasq.hosts  

Add the domain name you need to fill in the corresponding relationship, such as:

172.17.7.115 yongle.smartstudy.com 

Restart your DNS server, boot code in the article said, as of now, your Mac local DNS configuration is OK, but for other devices with the LAN, you need some action.

Modify the DHCP for the router

Configure DNS

172.17.7.115  

Standby DNS is configured as a general-use DNS server.

LAN devices need to re-connect WiFi, and then you can use your local DNS service, detection is successful, you can use the dig command, as you can on this machine:

dig yongle.smartstudy.com @127.0.0.1 

When you see

yongle.smartstudy.com.    0   IN  A 172.17.7.115 

Description success, this should be the end, but if there is a LAN device is not connected, you can check the DNS of the device is contained 172.17.7.115 , if not, restart the WiFi connection, OK.
