Below is a document I wrote a long time ago and posted it. 1. Install nginx1.1.

1. Nginx Chinese wiki http://wiki.codemongers.com/nginxchsdownload nginx 0.6.26 (Development version) (Please download the latest version)
2. Tar zxvf nginx-0.6.26.tar.gz
3. ./Configure. Pay attention to items similar to checking for ***... Not found. It may be that the dependency package does not exist, so you need to install the dependency package.
4. The PCRE is missing and sudo apt-Get install PCRE is installed. Or go to: http://www.pcre.org/
5. If OpenSSL is missing, sudo apt-Get install libssl-Dev, or go to: http://www.openssl.org
6. If zlib is missing, you can apt-Get install zlib1g, or http://www.zlib.net/
7. For configuration instructions, see http://wiki.codemongers.com/nginxchsinstall. you can select the installation module.
8. Make & make install
9. Installed in/usr/local/nginx by default

1. 2. Management

1. Execution options
   -C </path/to/config> specifies a configuration file for nginx to replace the default one.
   -T does not run, but only tests the configuration file. Nginx checks the syntax of the configuration file and tries to open the file referenced in the configuration file.
   -V displays the nginx version.
   -V displays the nginx version, compiler version, and configuration parameters.
2. Check the configuration file

   $ sudo nginx -t2008/03/12 19:15:11 info 12384#0: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok2008/03/12 19:15:11 info 12384#0: the configuration file /usr/local/nginx/conf/nginx.conf was tested successfully

3. Start

   /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

4. View nginx master process number

   $ ps -ef | grep "nginx: master process"
    | grep -v "grep"
    | awk -F ' ' '{print $2}
   26010

5. Reload the configuration file

   $sudo kill -HUP 26010

   Control nginx through System Signal
   You can use a signal system to control the main process. By default, nginx writes the PID of the main process to the/usr/local/nginx/logs/nginx. PID file. You can change the file location by passing the parameter to./configure or using the PID command.
   The main process can process the following signals:

   Command	Description	Remarks
   Term, int	Close quickly
   Quit	Easy to close
   Hup	Reload Configuration	Start a new working process with a new configuration and close the old working process with ease.
   Usr1	Re-open the log file
   Usr2	Smooth upgrade of executable programs
   Winch	Close the Working Process with ease

6. Default directory
   Main Directory:/usr/local/nginx/
   Configuration Directory:/usr/local/nginx/CONF/
   Root directory:/usr/local/nginx/html/
   Executable File Path:/usr/local/nginx/sbin/

2. fastcgi2.1. install spawn-FastCGI of Lighttpd

Download http://www.lighttpd.net/download/lighttpd-1.4.19.tar.gz

./configure    make    cp ./src/spawn-fcgi /usr/local/nginx/sbin/

2. Install the FastCGI Library

Download http://www.fastcgi.com/dist/fcgi.tar.gz

./configure    make    make install

2.3.hello world

#include <iostream>#include <fcgi_stdio.h>
using namespace std;
int main(){
    /* Initialization Code */
int count = 0;

    /* Start of response loop */
while (FCGI_Accept() >= 0)
    {
        //* body of response loop /*/
        printf("Content-type: text/html/r/n"               "/r/n"                ""
"FastCGI Hello/! (C, fcgi_stdio library)"                "Request number %d running on host %s "                "Process ID: %d/n",                /++count,                getenv("SERVER_NAME"), getpid());    }



    /* End of response loop */    return 0;


}

2. 4. Start spawn-CGI

/usr/local/nginx/sbin/spawn-fcgi -a 127.0.0.1 -p 9000 -C 25 -u www -f /usr/local/nginx/fcgi/FactCGISample

2. 5. Modify the nginx configuration file

VI/usr/local/nginx/CONF/nginx. conf

location ~ /.cgi$

{    
      fastcgi_pass 127.0.0.1:9000; 
      fastcgi_index index.cgi;
      fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
      include fastcgi_params;
}

Don't forget to reload the configuration file.

$sudo kill -HUP 26010

Open the browser and enter http: // localhost/1.cgito display

FastCGI Hello! (C, fcgi_stdio library)Request number 1 running on host localhost Process

 ID: 25473

3. webbench stress testing tool

Download: http://home.tiscali.cz: 8080 /~ Cz210552/distfiles/webbench-1.5.tar.gz

Installation:

tar zxvf webbench-1.5.tar.gzcd webbench-1.5


make && make install

Usage:

webbench -c 500 -t 30 http://127.0.0.1/test.jpg

500 is the number of concurrent connections, and 30 is the unit of time is second.

 

The result of testing with AB seems to have good performance on my virtual machine.

(Apache Plugin is an Apache toolkit)
