Updating Some Image Pip Package
Management Tools for CentOS 7：

Last updated 2023-05-08 17:48:19

Overview
Some Tencent Cloud CentOS 7 public images have Python 2-pip 8.1.2 installed by default. However, this version of
pip does not allow users to select compatible package versions to install. Instead, it defaults to installing the latest
packages. Unfortunately, the latest versions of pip and some commonly used application tools like NumPy do notsupport Python 2. As a result, when running a command to upgrade pip (pip install pip --upgrade) or installing specificapplication tools, compatibility issues may arise. To resolve this issue, Tencent Cloud has updated pip in some public
images of the CentOS 7 series.

Update Content and Scope
The table below lists the CentOS 7 public images with updated pip. By default, these public images have Python 2
installed, which comes with pip 20.3.4 instead of pip 8.1.2.
Note:
The upgrade has been performed in stages and finished on December 12, 2022. Instances purchased after the
upgrade of a corresponding public image are automatically updated, while instances purchased prior to the upgrade
are not. To update these instances, refer to the manual upgrade instructions.

Stopping supporting for Ubuntu 10.04 images：

Last updated 2022-04-06 18:34:54
Ubuntu has officially ceased providing maintenance for Ubuntu 10.04 LTS, and therefore Tencent Cloud has also
deactivated public images of Ubuntu 10.04.
Directory trees for Ubuntu 10.04 LTS have been deleted from the latest official source repository. To ensure
consistency with the official source repository, the Tencent Cloud software repository will no longer support Ubuntu
10.04 LTS under the official source directory tree. Accordingly, we recommend that you upgrade your images to a later
version.
For existing users who hope to continue to use the software source of Ubuntu 10.04, we provide support for them inthe following ways:

Method 1: Manually Updating the Configuration File
To improve the user experience, the Tencent Cloud software repository pulls the official archive source
http://old-releases.ubuntu.com/ubuntu/ of Ubuntu 10.04 LTS (http://old-releases.ubuntu.com/ubuntu/)
for users. Users can use the repository as usual by manually modifying the configuration file:
Open the apt source configuration file vi/etc/apt/sources.list and modify the following code snippets:©2013-2022 Tencent Cloud. All rights reserved.

Solution to Tomcat Start Failure on
Ubuntu14.04：

Last updated 2022-04-06 18:34:54
It has been detected that when Tomcat or Hadoop is installed via apt-get command on a Ubuntu14.04 CVM
purchased from Tencent Cloud, it can listen to the port but cannot respond to requests. A solution is now available.
We recommend following the instructions below if you encounter this issue.

CausesThis issue is caused by a known Java Runtime Environment issue.

Analysis
Both Tomcat and Hadoop are developed using the Java java.security.SecureRandom API.
This API uses /dev/random as a random number generator by default in some JREs. /dev/random
accesses environmental noises collected from devices such as CPU temperature or keyboard timings to generateentropy. However, the virtual environment of CVMs makes it difficult to access such noises and generate entropy,
causing cat /dev/random to block Tomcat and Hadoop from being started.

Solution
Modifying the JRE configuration
Please change securerandom.source=file:/dev/urandom in the original /etc/java-7openjdk/security/java.security (use actual URL) tosecurerandom.source=file:/dev/./urandom to resolve this issue.

Cloud Virtual MachineInternet Domain Name Resolution establishes the relationship between an Internet domain name and its
corresponding IP address.
Internet domain name resolution service builds domain name resolution servers and related software on theInternet to translate Internet domain names to their corresponding IP addresses. There are two types of domain nameresolution services: authoritative and recursive resolution services.
Authoritative resolution: This service provides domain name resolution for root domain names, top-level domainnames, and other levels of domain names.
Recursive resolution: This service establishes the correspondence between domain names and IP addresses byquerying the local cache or the authoritative resolution service system.
Internet domain name resolution service here specifically refers to recursive resolution service. For more information,
see “Classification Catalog of Telecommunications Services” (2015 Edition): B26-1 Internet domain name resolution
services.

If you do not engage in Internet domain name resolution services, disabling port 53 through inbound rules does not
impact your server or business.

Can individual engage in domain name resolution services?
Telecommunications services providers must have established businesses in accordance with the law. An individual
cannot engage in this type of service. You must obtain an “Code and Protocol Conversion License” before carrying out
