TOMCAT cluster instance analysis under NGINX reverse proxy in LINUX

TOMCAT cluster instance analysis under NGINX reverse proxy in LINUX

nginx has features such as reverse proxy (note the difference between forward proxy and forward proxy) and load balancing. This time nginx is installed on the linux machine 192.168.1.108. To install nginx, you must first install the openssl library, gcc, pcre, zlib library, etc. Tomcat is installed on two machines, 192.168.1.168 and 192.168.1.178. The client accesses the project content deployed by tomcat in 192.168.1.168 and 192.168.1.178 by accessing the 192.168.1.108 reverse proxy. 1.

How nginx implements load balancing and multi-site sharing session

How nginx implements load balancing and multi-site sharing session

Common methods for multi-site sharing sessions include: • Using .net automatic state service (asp.netstateservice); • Using .net session database; • Using memcached. •Use cookies to achieve sharing between multiple sites (this method is limited to when several sites are in the same domain name); here we will practice storing sessions in the form of a database to achieve multi-site sharing sessions. First, we build the site, as shown below: default.aspx has two buttons. Setsession is mainly used to assign values ​​to a session (such as: session

How to use Nginx as a Perl program server and its Perl module under Linux

How to use Nginx as a Perl program server and its Perl module under Linux

Building perl+fastcgi+nginx nginx+fastcgi is the most popular environment under PHP. Will perl also have fastcgi? Of course it does. Today, let’s build perl’s fastcgi under nginx. The performance is no less than that of PHP. But now the popularity of the web program PHP is unmatched by perl. No matter how good the performance is, it is in vain. However, some small functions can be solved by using perl's fastcgi. Let's get to the point. 1. Prepare the software environment: nginxperl: The system comes with fastcgi1.2perl installation Generally, Linux comes with perl, so you don’t need to install it. If it doesn’t, please execute:

How to solve nginx server configuration CPU error

How to solve nginx server configuration CPU error

First, check the possibility of customer problems: Due to excessive traffic on the website, the number of IP addresses exceeds one million per day, which causes the CPU to increase crazily and directly to 100% operating rate, causing the server to crash and freeze. After several days of research, we came to a result: That is, the connection is blocked, causing an endless loop of crashes. After each crash, as long as it is restarted, it will be blocked and crashed again about 2-3 hours later. After the programmer's analysis, it may be that the traffic exceeds the delay and causes the crash. So what is the solution to frequent CPU alarms when encountering nginx server configuration: First, you need to determine whether the server configuration is sufficient, and this user is using a BGP server, the bandwidth and configuration are sufficient E5-2650V4*232G Memory 250G Samsung SSD, so

How to integrate nginx with lua to operate mysql

How to integrate nginx with lua to operate mysql

The implementation idea is to directly configure the blacklist in nginx and implement it by writing logical blocks; write the filter in the server (Java) and unify the interceptors in the filter; write the interceptor in the server (Java) and unify the interceptors Interception; here are 3 implementation ideas. As for implementation solutions, there may be more, but if we think about it, writing logical blocks in nginx does not seem to be what many people are good at; it is not impossible to do it at the code level, but this is First, during peak business periods involving high concurrency, this will inevitably put greater pressure on back-end services. So are there any other better ways to deal with it? This is what lua is about, that is, nginx acts as a gateway and still acts as a proxy server, because nginx can integrate lua

Analysis of example code for installing nginx under linux

Analysis of example code for installing nginx under linux

Linux system is centos 64-bit introduction 1. Common methods for Linux installation software 1. rpm (or pkg) installation, similar to the windows installation program, is a precompiled program. General parameter compilation is used, and the configuration parameters are not optimal and controllable. For example, customized installation of specific components of the program usually has complex dependencies between installation packages, making the operation complex and easy to install, with a low error rate. 2. yum (or apt -get) installation, an improved version of rpm, automatically downloads installation packages online, and automatically manages dependencies 3. Compilation and installation (the method is not very different among various Linux distributions) is highly controllable, and can be optimized according to the current system environment during config Parameters, customizable components and easy installation parameters

How to optimize Nginx configuration and kernel

The optimization (configuration file) copy code in the nginx instruction is as follows: worker_processes8; The number of nginx processes is recommended to be specified according to the number of cpu, usually a multiple of it. Copy the code as follows: worker_cpu_affinity0000000100000010000001000000100000010000001000000100000010000000; Assign a CPU to each process. In the above example, 8 processes are assigned to 8 CPUs.

How to access multiple projects with one domain name in Nginx

How to access multiple projects with one domain name in Nginx

Introduction to matching of location module 1. "=" prefix directive matching, if the matching is successful, other matching will be stopped. 2. Ordinary string instructions are matched in order from longest to shortest. If the successfully matched location uses ^~, other matching will be stopped (regular matching). 3. Regular expression instructions are matched according to the order in the configuration file. If successful, other matching will be stopped. 4. If there is a successful match in the third step, use the result, otherwise use the second step result. Note 1. The matching order is to match ordinary strings first, and then match regular expressions. In addition, the matching order of ordinary strings is based on the character length in the configuration from long to short, which means that the order of locations configured using ordinary strings is irrelevant, anyway.
