Nginx

公司刚使用nginx,预先学习下。鉴于机器没有Linux环境,在Windows熟悉下。

下载

1)下载地址:

  http://nginx.org

目前(2017-05-30),nginx的稳定版本是,在官网下载先,12.0

2017-04-25

nginx-1.13.0 mainline version has been released.

2017-04-12

nginx-1.12.0 stable version has been released, incorporating new features and bug fixes from the 1.11.x mainline branch - including variables support and other improvements in the stream moduleHTTP/2 fixes, support for multiple SSL certificates of different types, improved dynamic modules support, and more.

这是一个zip文件,解压后即可使用(我是放在d:)

启动

绿色文件,无须安装,直接即可启动。

据我所知,3种启动途径,其实都类似:

一、双击nginx.exe图标,可见黑窗口一闪而过,启动完毕。

二、命令行到nginx目录,输入nginx启动。(注,此方式命令行窗口无任何提示,且被锁定)

三、命令行到nginx目录,输入start nginx启动,此方式不锁定

启动后,默认情况下(无修改配置),可见到有两个nginx的进程,1个是master process,1个是worker processes。

如果你在配置中配置2个worker_processes,进程中就可以看到1个是master process,2个是worker processes。

测试

默认nginx部署了些静态内容,我们可通过它测试nginx是否在工作。

默认的配置文件(NGINX_HOME/conf/nginx.conf)如下:

复制代码
#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 / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

}
复制代码

通过观察配置文件的非注释项(参考Nginx配置文件nginx.conf中文详解),大概可知:

1、启动了1个worker processes

2、worker_connections,最大并发数为1024

3、include mime.types,引入mime.types文件所声明的文件扩展名与文件类型映射

4、application/octet-stream,默认使用application/octet-stream

5、sendfile,开启高效文件传输模式

6、监听本机“localhost”的80端口

7、映射目录为“当前目录的html目录”

8、出现500、502、503、504错误,则映射到50x.html

浏览地址http://localhost,即可访问其默认页面,即映射到NGINX_HOME/html/index.html

其他静态内容,如html、图片,可自行添加测试。

日志

日志默认位于NGINX_HOME/logs/,可见:

1、access.log,访问日志

2、error.log,异常日志

3、nginx.pid,进程(仅在启动nginx后才有此日志)
