How do I allow MySQL connections through SELinux? - Server Fault

https://serverfault.com/questions/240015/how-do-i-allow-mysql-connections-through-selinux

Saved by uncleflo on July 11th, 2019.

I'd like to for once leave SELinux running on a server for the alleged increased security. I usually disable SELinux to get anything to work. How do I tell SELinux to allow MySQL connections? The most I've found in the documentation is this line from mysql.com: If you are running under Linux and Security-Enhanced Linux (SELinux) is enabled, make sure you have disabled SELinux protection for the mysqld process.

AWS Aurora MySQL – HA, DR, and Durability Explained in Simple Terms - Percona Database Performance Blog

https://www.percona.com/blog/2019/01/11/aws-aurora-mysql-ha-dr-and-durability-explained-in-simple-terms/

Saved by uncleflo on July 11th, 2019.

It’s a few weeks after AWS re:Invent 2018 and my head is still spinning from all of the information released at this year’s conference. This year I was able to enjoy a few sessions focused on Aurora deep dives. In fact, I walked away from the conference realizing that my own understanding of High Availability (HA), Disaster Recovery (DR), and Durability in Aurora had been off for quite a while. Consequently, I decided to put this blog out there, both to collect the ideas in one place for myself, and to share them in general. Unlike some of our previous blogs, I’m not focused on analyzing Aurora performance or examining the architecture behind Aurora. Instead, I want to focus on how HA, DR, and Durability are defined and implemented within the Aurora ecosystem.  We’ll get just deep enough into the weeds to be able to examine these capabilities alone.

How are you guys handling QA environments on AWS? : aws

https://www.reddit.com/r/aws/comments/9hhxiv/how_are_you_guys_handling_qa_environments_on_aws/

Saved by uncleflo on July 11th, 2019.

News, articles and tools covering Amazon Web Services (AWS), including S3, EC2, SQS, RDS, DynamoDB, IAM, CloudFormation, Route 53, CloudFront, Lambda, VPC, Cloudwatch, Glacier and more. Just a curiosity. At this point I've done: single staging environment for small teams, and that obviously doesn't work well beyond a couple; one off EC2 instances that just use docker to make a mini-replicated environment; cloudformation to spin up an entire, and yet smaller, version of our production; ngrok and just having our QA test directly. The area I'm interested to see how people are handling it is with respect to data. Are you replicating the full DB? Just using in memory and some seed data? Additionally, for those of you that have this (or have had one in the past), how did you guys set it up to be "pleasurable" to work with? By that I mean it not being some long winding rube goldberg machine that almost defeats the purpose of having a CI.

Working with Amazon Aurora Global Database - Amazon Aurora

https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/aurora-global-database.html

Saved by uncleflo on June 23rd, 2019.

Following, you can find a description of Amazon Aurora Global Database. Each Aurora global database spans multiple AWS Regions, enabling low latency global reads and disaster recovery from region-wide outages. An Aurora global database consists of one primary AWS Region where your data is mastered, and one read-only, secondary AWS Region. Aurora replicates data to the secondary AWS Region with typical latency of under a second. You issue write operations directly to the primary DB instance in the primary AWS Region. An Aurora global database uses dedicated infrastructure to replicate your data, leaving database resources available entirely to serve application workloads. Applications with a worldwide footprint can use reader instances in the secondary AWS Region for low latency reads. In the unlikely event your database becomes degraded or isolated in an AWS region, you can promote the secondary AWS Region to take full read-write workloads in under a minute.

AWS - How to redirect database traffic to a new master on RDS after promoting a read replica? - Server Fault

https://serverfault.com/questions/780605/how-to-redirect-database-traffic-to-a-new-master-on-rds-after-promoting-a-read-r

Saved by uncleflo on June 23rd, 2019.

A lot of RDS's documentation about read replicas contains a magical step along the lines of "direct database traffic to the new master." For instance, their instructions on implementing failure recovery say: This talk about directing traffic glosses over what is actually a complicated step, though. If I were using EC2 instances to host my database, I could give them elastic IPs, use the public DNS address of the instance to address it (which resolves to its private IP from inside AWS), and then instantly swap my entire stack to the read replica by reassigning the elastic IP (and thus simultaneously reassigning the public DNS). I used this method happily back in the days when RDS was considered straightforwardly inferior to rolling your own database instance on EC2 by many DBAs. RDS instances still cannot have elastic IPs, though, so I cannot use this particular trick to magically redirect all my database traffic to a new instance when using RDS.

PHP Unit Testing with PHPUnit | Udemy

https://www.udemy.com/php-unit-testing/

Saved by uncleflo on June 23rd, 2019.

Learning how to write unit tests for your code will make you write better code. With automated tests, you can find bugs more easily, and if you break something you'll notice straight away. Many experienced developers write unit tests for their code. It's a repeatable way of checking that the code works as intended, and also serves as documentation. Many popular PHP projects are unit tested, such as WordPress and Moodle, and if you use frameworks such as Laravel or Symfony, these provide tight integration with the PHPUnit testing framework.

sql - MySql : Grant read only options? - Stack Overflow

https://stackoverflow.com/questions/20036547/mysql-grant-read-only-options

Saved by uncleflo on June 23rd, 2019.

Is there a way to group all read operations in grant ? If there is any single privilege that stands for ALL READ operations on database. "Reading" from tables and views is the SELECT privilege. If that's what you mean by "all read" then yes: However, it sounds like you mean an ability to "see" everything, to "look but not touch." So, here are the other kinds of reading that come to mind: "Reading" the definition of views is the SHOW VIEW privilege. "Reading" the list of currently-executing queries by other users is the PROCESS privilege.

UTF-8 Sampler

http://kermitproject.org/utf8.html

Saved by uncleflo on June 23rd, 2019.

UTF-8 is an ASCII-preserving encoding method for Unicode (ISO 10646), the Universal Character Set (UCS). The UCS encodes most of the world's writing systems in a single character set, allowing you to mix languages and scripts within a document without needing any tricks for switching character sets. This web page is encoded directly in UTF-8. This, however, is a Web page, which started out as a kind of stress test for UTF-8 support in Web browsers, which was spotty when this page was first created in the 1990s but which has become standard in all modern browsers. The problem now is mainly the fonts and the browser's (or font's) support for the nonzero Unicode planes (as in, e.g., the Braille
and Gothic examples below). And to some extent the rendition of combining sequences, right-to-left rendition (Arabic,
Hebrew), and so on. The subtitle above shows currency symbols of many lands. If they don't appear as blobs, we're off to a good start!

Unicode character property - Wikipedia

https://en.wikipedia.org/wiki/Unicode_character_property

Saved by uncleflo on June 23rd, 2019.

The Unicode Standard assigns character properties to each code point. These properties can be used to handle "characters" (code points) in processes, like in line-breaking, script direction right-to-left or applying controls. Slightly inconsequently, some "character properties" are also defined for code points that have no character assigned, and code points that are labeled like "<not a character>". The character properties are described in Standard Annex #44.

Power your metrics and alerting with a leadingopen-source monitoring solution. Prometheus implements a highly dimensional data model. Time series are identified by a metric name and a set of key-value pairs. PromQL allows slicing and dicing of collected time series data in order to generate ad-hoc graphs, tables, and alerts. Prometheus has multiple modes for visualizing data: a built-in expression browser, Grafana integration, and a console template language. Prometheus stores time series in memory and on local disk in an efficient custom format. Scaling is achieved by functional sharding and federation. Each server is independent for reliability, relying only on local storage. Written in Go, all binaries are statically linked and easy to deploy.

Containers: A Complete Guide | IBM

https://www.ibm.com/cloud/learn/containers

Saved by uncleflo on May 12th, 2019.

This guide looks at the importance of containers in cloud computing, highlighting the benefits and showing how containers figure into such technologies as Docker, Kubernetes, Istio, VMs, and Knative. A container is a small file that packages together application code along with all the libraries and other dependencies that it needs to run. By packaging together applications, libraries, environment variables, other software binaries and configuration files, a container guarantees that it has everything needed to run the application out of the box, regardless of the operating environment in which the container runs. A key characteristic of a container is that it is small and fast because it uses some of the underlying host operating system's resources to run rather than containing a whole OS of its own.

In SQL Server, you can create a database user to allow different users or processes access to a particular database. Even though we have just created a login that can successfully connect to SQL Server, that login still can't access our Music database. This is because we haven't yet associated that login with a database user. There are four things you need to do in order to provide access to a database:

Waterfall model - Wikipedia

https://en.wikipedia.org/wiki/Waterfall_model

Saved by uncleflo on January 18th, 2019.

The waterfall model is a relatively linear sequential design approach for certain areas of engineering design. In software development, it tends to be among the less iterative and flexible approaches, as progress flows in largely one direction ("downwards" like a waterfall) through the phases of conception, initiation, analysis, design, construction, testing, deployment and maintenance. The waterfall development model originated in the manufacturing and construction industries; where the highly structured physical environments meant that design changes became prohibitively expensive much sooner in the development process. When first adopted for software development, there were no recognized alternatives for knowledge-based creative work.
