常用nginx配置项详解（一个简单的例子）

#运行用户 
user nobody nobody; 
#启动进程 
worker_processes 2; 
#全局错误日志及PID文件 
error_log logs/error.log notice; 
pid logs/nginx.pid; 
#工作模式及连接数上限 
events { 
use epoll; 
worker_connections 1024; 
} 
#设定http服务器，利用它的反向代理功能提供负载均衡支持 
http { 
#设定mime类型 
include conf/mime.types; 
default_type application/octet-stream; 
#设定日志格式 
log_format main ‘$remote_addr – $remote_user [$time_local] ‘ 
‘”$request” $status $bytes_sent ‘ 
‘”$http_referer” “$http_user_agent” ‘ 
‘”$gzip_ratio”‘; 
log_format download ‘$remote_addr – $remote_user [$time_local] ‘ 
‘”$request” $status $bytes_sent ‘ 
‘”$http_referer” “$http_user_agent” ‘ 
‘”$http_range” “$sent_http_content_range”‘; 
#设定请求缓冲 
client_header_buffer_size 1k; 
large_client_header_buffers 4 4k;

#开启gzip模块 
gzip on; 
gzip_min_length 1100; 
gzip_buffers 4 8k; 
gzip_types text/plain; 
output_buffers 1 32k; 
postpone_output 1460; 
#设定access log 
access_log logs/access.log main; 
client_header_timeout 3m; 
client_body_timeout 3m; 
send_timeout 3m; 
sendfile on; 
tcp_nopush on; 
tcp_nodelay on; 
keepalive_timeout 65; 
#设定负载均衡的服务器列表 
upstream mysvr { 
#weigth参数表示权值，权值越高被分配到的几率越大 
#本机上的Squid开启3128端口 
server 192.168.8.1:3128 weight=5; 
server 192.168.8.2:80 weight=1; 
server 192.168.8.3:80 weight=6; 
} 

#设定虚拟主机 
server { 
listen 80; 
server_name 192.168.8.1 www.hahaer.com; 
charset gb2312; 
#设定本虚拟主机的访问日志 
access_log logs/www.hahaer.com.access.log main; 
#如果访问 /img/*, /js/*, /css/* 资源，则直接取本地文件，不通过squid 
#如果这些文件较多，不推荐这种方式，因为通过squid的缓存效果更好 
location ~ ^/(img|js|css)/ { 
root /data3/Html; 
expires 24h; 
}

#对 “/” 启用负载均衡 
location / { 
proxy_pass http://mysvr;

proxy_buffer_size 4k; 
proxy_buffers 4 32k; 
proxy_busy_buffers_size 64k; 
proxy_temp_file_write_size 64k; 
}

#设定查看Nginx状态的地址 
location /NginxStatus { 
stub_status on; 
access_log on; 
auth_basic “NginxStatus”; 
auth_basic_user_file conf/htpasswd; 
} 
} 
}

location ~* .*\.(js|css)?$
{
        expires 7d; //7天过期,后续讲解
        access_log off; //不保存日志
}
 
location ~* .*\.(png|jpg|gif|jpeg|bmp|ico)?$
{        
        expires 7d;

}
 
location ~* .*\.(zip|rar|exe|msi|iso|gho|mp3|rmvb|mp4|wma|wmv|rm)?$
