nginx学习整理

nginx配置文件说明

nginx.conf位于其安装目录的conf目录下

  1. user是个主模块指令,指定Nginx Worker进程运行用户以及用户组,默认由nobody账号运行。

  2. worker_processes:主模块指令,指定了Nginx要开启的进程数。每个Nginx进程平均耗费10M~12M内存。建议指定和CPU的数量一致即可。

  3. error_log:主模块指令,用来定义全局错误日志文件。日志输出级别有debug、info、notice、warn、error、crit可供选择,其中,debug输出日志最为最详细,而crit输出日志最少。

  4. pid是个主模块指令,用来指定进程pid的存储文件位置

  5. worker_rlimit_nofile用于绑定worker进程和CPU, Linux内核2.4以上可用。

  6. events事件指令是设定Nginx的工作模式及连接数上限:

#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;
sendfile on;
#tcp_nopush on;

#keepalive_timeout  0;
keepalive_timeout  65;

#gzip  on;

server {
    listen       8888;                    //监听的端口号
    server_name  localhost;     //监听的服务名称
    
    location ~/group([0-9])/M00 {
        #alias /fastdfs/storage/data;
        ngx_fastdfs_module;
    }
    
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   html;
    }

    #location ~ \.php$ {                      //以.php结尾的文件,请求发到http://127.0.0.1服务器
    #    proxy_pass   http://127.0.0.1;
    #}

    #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;
