Cohoha VPS Host to add multiple independent IP address and system configuration detailed

In this article the old left not to discuss the Cohoha data center (with more Japanese and Singapore) performance and speed stability, because there are many users in the use of the old left also opened Singapore room in use, and stability is still acceptable. The default Conoha VPS host only a separate IPV4 address, if some of our projects may need to add multiple IP address use, such as our VPS to add multiple independent IP, so different sites to assign different independent IP, you can save a certain cost.

After appending the independent IP, does not automatically match to the system, we need to make the configuration file the setting. Because in the past some time to see a lot of netizens have mentioned that there is such a demand, so I will open a separate machine directly, and then add independent IP for testing configuration. Here needs to mention is that the VPS host default space is in accordance with the hourly deduction fee, if the IP address separately added, 30 days is not deleted.

First, append multiple independent IP address

Default we open VPS host only assign a IPV4 address to us, if we need (if not necessary, do not toss), then according to the following scheme to add a new independent IP address.

1, additional IP address

In the background panel, network-Append IP address.

2. Select room and number

Then we choose according to the room area of the demand and the number of IP addresses we need.

3, determine the payment cycle

We can see the requirements, additional independent IP address can not be deleted within 30 days, from the cost of the new Japanese independent IP address, January is 350 yen, equivalent to 18 yuan or so (the cost of sharing the article is quite high, for the authenticity of the article, but also really need to open an independent IP out).

4, configuration to the VPS host

We need to suspend the current VPS operation and then proceed to configure the VPS. After the completion of the installation of the VPS host reboot, restart the new IP is not available, we need to configure the file can be.

Second, the new IP address configuration file

This step is still more important, although there are many similar tutorials on the web, but not as accurate as the official documentation provided, which is not based on the official documentation tutorials previously provided by P.

1, Login VPS and determine ETH address

The code is as follows	Copy Code
Ifconfig-a

And then view

The code is as follows	Copy Code
eth1 Link encap:ethernet hwaddr fa:16:xx:xx:xx:xx

The red part needs to be recorded and will need to be used below.

2, set eth1 profile information

The code is as follows	Copy Code
Vi/etc/sysconfig/network-scripts/ifcfg-eth1

Add the following script

The code is as follows	Copy Code
Device= "Eth1" Hwaddr= "Fa:16:xx:xx:xx:xx" #上面获得的MAC地址 bootproto= "Static" Nm_controlled= "No" onboot= "Yes" Type= "Ethernet" Ipaddr= "XX. Xx. Xx. XX "#我们的新追加IP地址 netmask= "255.255.254.0"

Save the file after you add it.

3. Set Routing strategy

The code is as follows	Copy Code
Vi/etc/iproute2/rt_tables

Add a row of rules

The code is as follows	Copy Code
201 GW1

Added in.

The code is as follows	Copy Code
Vi/etc/sysconfig/network-scripts/route-eth1

Append IP Gateway setting policy.

The code is as follows	Copy Code
Default via Xxx.xxx. xxx.1 Table Gw1

Current IP address gateway settings.

The code is as follows	Copy Code
Vi/etc/sysconfig/network-scripts/rule-eth1
