DevOps Troubleshooting: Linux Server Best Practices ペーパーバック – 2012/9/24
&;Trotter Cashion, cofounder, Mashion
DevOps can help developers, QAs, and admins work together to solve Linux server problems far more rapidly, significantly improving IT performance, availability, and efficiency. To gain these benefits, however, team members need common troubleshooting skills and practices.
In DevOps Troubleshooting: Linux Server Best Practices, award-winning Linux expert Kyle Rankin brings together all the standardized, repeatable techniques your team needs to stop finger-pointing, collaborate effectively, and quickly solve virtually any Linux server problem. Rankin walks you through using DevOps techniques to troubleshoot everything from boot failures and corrupt disks to lost email and downed websites. You&;ll master indispensable skills for diagnosing high-load systems and network problems in production environments.
Rankin shows how to
- Master DevOps&; approach to troubleshooting and proven Linux server problem-solving principles
- Diagnose slow servers and applications by identifying CPU, RAM, and Disk I/O bottlenecks
- Understand healthy boots, so you can identify failure points and fix them
- Solve full or corrupt disk issues that prevent disk writes
- Track down the sources of network problems
- Troubleshoot DNS, email, and other network services
- Isolate and diagnose Apache and Nginx Web server failures and slowdowns
- Solve problems with MySQL and Postgres database servers and queries
- Identify hardware failures&;even notoriously elusive intermittent failures

Hope author writes some more books and Linux ..
I'm primarily a Java developer, and working as a contractor in small startup companies I often have to work across the entire stack from instance/OS administration right though to creation of web-based UIs. The term 'DevOps' is obviously getting a lot of attention in the computing/development press, and the type of companies I work for are increasingly expecting this to be a skill I should have (even if they don't know exactly what DevOps encompasses!).
I needed to improve my DevOps skills fast, and coming at this from a developer's point-of-view the primary skills I need to learn are the Ops-based System Administration (sysadmin) tasks - this book meets that requirement exactly. The book is small, but don't take this as a negative - it is highly focused, and contains a wealth of knowledge. I managed to devour the contents over a day, mainly by reading a chapter, taking a pause to experiment with my new-found knowledge and commands using a Linux-based box, and then dipping back into the book if I got stuck.
A particular use case that this book matches perfectly is the new wave of developers deploying to the Cloud. Over the past few years I am increasingly deploying a client's app to Cloud-based infrastructure such as AWS (EC2, RDS etc), and the rules of engagement are quite different here in comparison to when deploying to in-house boxes. I've lost count of the amount of time I've thrown away trying to figure out performance problems with Cloud apps - is the app poorly designed, or am I IO/Compute/network bound? The skills you'll acquire from this book will help considerably here (for example, I didn't know about the sar command, which is *extremely* useful for monitoring resources over time!)
If you're coming from a similar background to me and are looking for a good package of Linux sysadmin knowledge then in addition to this book I would recommend the Linux Pocket Guide for day-to-day reference (I always keep this book close by, and it helps greatly when I'm struggling to remember the netstat syntax or vim shortcuts) and the Pro Linux System Administration (Expert's Voice in Open Source) for the complete 'weighty-tome' reference.
If you're coming from a developer background and are looking to break into the murky world of DevOps then I strongly recommend this book as a starting point - the author has clearly thought about the goals of this book and has done a great job in meeting them!
