  • 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)
