Nginx - Getting started with Nginx under Windows, with the installation of Nginx under CentOS

1. Download

At present (2015-07-11), the stable version of nginx is 1.8.0, download it from the official website first, the windows version of nginx 1.8.0

This is a zip file that can be used after unzipping

 

2. Start

The green file can be started directly without installation.

As far as I know, the 3 startup paths are actually similar:

1. Double-click the nginx.exe icon, a black window can be seen flashing by, and the startup is complete.

Second, the command line to the nginx directory, enter nginx to start. (Note, in this way the command line window has no prompts and is locked)

3. Go to the nginx directory from the command line, enter start nginx to start, this method is not locked

 

After startup, by default (without modifying the configuration), you can see that there are two nginx processes, one is the master process and the other is the worker process.

 

If you configure 2 worker_processes in the configuration, you will see 1 master process and 2 worker processes in the process.

3. Test

By default nginx deploys some static content, we can use it to test whether nginx is working.

The default configuration file (NGINX_HOME/conf/nginx.conf) is as follows:

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   html;
            index  index.html index.htm;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ \.php$ {
        #    proxy_pass   http://127.0.0.1;
        #}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        #location ~ \.php$ {
        #    root           html;
        #    fastcgi_pass   127.0.0.1:9000;
        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        #    include        fastcgi_params;
        #}

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }


    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}


    # HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;

    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    ssl_session_cache    shared:SSL:1m;
    #    ssl_session_timeout  5m;

    #    ssl_ciphers  HIGH:!aNULL:!MD5;
    #    ssl_prefer_server_ciphers  on;

    #    location / {

    #    }
    #}

By observing the non-commented items of the configuration file (refer to the detailed explanation of the Nginx configuration file nginx.conf in Chinese ), we can know that:

1. Started a worker process

2. worker_connections, the maximum concurrent number is 1024

3. include mime.types, import the file extension and file type mapping declared by the mime.types file

4. application/octet-stream, use application/octet-stream by default

5, sendfile, open the efficient file transfer mode

6. Listen to port 80 of the local "localhost"

7. The mapping directory is "html directory of the current directory"

8. If 500, 502, 503, 504 errors occur, map to 50x.html

 

Browse the address http://localhost to access its default page, which is mapped to NGINX_HOME/html/index.html

Other static content, such as html and pictures, can be tested by themselves.

4. Logs

The log is located in NGINX_HOME/logs/ by default, which can be seen:

1, access.log, access log

2, error.log, exception log

3. nginx.pid, process (this log is only available after starting nginx)

 

5. Installation of Nginx under CentOS

tar -zxvf nginx-1.8.0.tar.gz
cd nginx-1.8.0
./configure
make
make install
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

 

After the installation is complete, check the process and related logs:

ps -ef | grep nginx
less /usr/local/nginx/logs/error.log
less /usr/local/nginx/logs/nginx.pid
less /usr/local/nginx/logs/access.log
