The second edition of Progressive Linux will be released (with cover)
From the first edition of "Progressive Linux" released, to now nearly 6 years, 6 years, the technology has changed a lot, the kernel version of Linux system from 2.6.9 (rhel4.x) has been updated to the current 3.10 (centos7.x), the first version of some of the content is obsolete, the Linux system part of the operating mechanism has changed a lot, in order to adapt to the technological trend, and for all the readers who support this book, I decided to revise the book, The introduction of "Progressive Linux" Second edition.
The second version of the basic inheritance of the first version of the content structure, the basic Redhat Linux, CentOS Two Linux distribution mainly introduced, the specific version is centos7.x/ rhel7.x, will be more prominent in the chapter, the theory and practice, the enterprise case and the application of actual combat part will increase;
In the basic knowledge section, we briefly introduce the application fields of Linux, then introduce some methods and techniques of mastering Linux Learning, then introduce the installation and system structure of Linux, and also introduce the common commands and usage techniques under Linux, as well as the installation method of Linux software.
In the server building chapter, remove the original content, but also added the content of MySQL database, mainly introduces the application of high-performance MySQL database, but also increased the lamp service environment, and then in the server security policy and troubleshooting to add a lot of experience and technical summary, it is worth a look.
In the system administration, this part of the content basically unchanged, mainly revised the file system management and memory management of some content, adding some of the latest Linux technology features.
In the performance tuning chapter, the case of system optimization is added on the basis of original theory, and the experience of system optimization is introduced by combining theory with practice.
In the virtualization, cluster application, this part is the highlight of the book, basically completely revised the original content, three chapters respectively introduced the Proxmox ve Virtualization Guan Ping platform, as well as high-availability software keepalived, load balancer software LVS and Haproxy, the introduction of the method is very accessible, The previous introduction of software applications, the following through the specific enterprise case, from the perspective of production application, introduced the enterprise environment commonly used in two high-availability cluster applications, it can be said that this is the whole book of content integrated application part, from the perspective of application of the enterprise high-availability cluster environment of the building and maintenance process.
