入门第四篇 ：Nginx搭建图片服务器

摘要: Nginx图片服务器

Nginx搭建图片服务器

Nginx下载地址：http://nginx.org/en/download.html

本例下载的是window版本nginx-1.6.1

以下是我本机操作说明：

下载完后，解压，并把它放到D:\tools\nginx-1.6.1，双击nginx.exe即可运行nginx。可通http://127.0.0.1访问到nginx欢迎界面

也可在cmd中通过命令进行启停启动nginx：

start nginx //运行nginx

nginx -s stop // 停止nginx

nginx -s reload // 重新加载配置文件(如修改配置文件后，可通过该命令重新加载)

nginx -s quit // 退出nginx

nginx -v //可查nginx版本

在执行nginx命令时，出现了 windows nginx: [error] CreateFile() "logs/nginx.pid" failed 异常。原因是未指定

nginx.conf，指定该文件，启动命令如下：

D:\tools\nginx-1.6.1>nginx -c D:\tools\nginx-1.6.1\conf\nginx.conf

接下来我们配置图片服务器：

1、在本地建了一个D:\resourcesfile\images文件夹，里面放了一张png测试图片。

2、配置nginx.conf文件，配置文件内容如下：

Xml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;

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 8089;#端口号

server_name localhost;#本机

charset utf-8;

#access_log logs/host.access.log main;

location ~ .*\.(gif|jpg|jpeg|png)$ {

expires 24h;

root D:/resourcesfile/images/;#指定图片存放路径

access_log D:/tools/nginx-1.6.1/logs/log_test.log;#图片路径

proxy_store on;

proxy_store_access user:rw group:rw all:rw;

proxy_temp_path D:/resourcesfile/images/;#图片路径

proxy_redirect off;

proxy_read_timeout 900;

proxy_buffer_size 40k;

proxy_buffers 40 320k;

proxy_busy_buffers_size 640k;

proxy_temp_file_write_size 640k;

if ( !-e $request_filename)

{

proxy_pass http://127.0.0.1:8089;#代理访问地址
}

}

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;

# }

#}

}

配置完后，执行reload命令重新加载配置文件。然后进行访问图片，http://127.0.0.1:8089/036367.png

如果能访问，说明搭建成功。接下来还需对缓存和安全性进行研究。

===============================================================================

Linux下安装nginx，需要先安装Gcc编译器、PCRE库、zlib库、OpenSSL开发库。然后再安装nginx，

解压：tar -zxvf nginx-1.3.15.tar

编译安装命令：

./configure

make

make install

Linux下配置nginx图片服务器：

nginx version: nginx/0.6.35

nginx启动：/opt/nginx/sbin/nginx -c /opt/nginx/conf/nginx.conf

nginx关闭：ps -au|grep nginx

然后kill -9 进程id 或 killall -9 nginx

nginx.conf配置文件内容如下：

配置过程问题汇总：

1、failed Permission denied 权限问题

修改nginx.conf文件中

user nobody

改成：user root

2、nginx中Too many open files的问题

可参考相关博文 http://www.01happy.com/nginx-too-many-open-files/ http://zlr.iteye.com/blog/1961257
3、nginx recv() failed (104: Connection reset by peer) while reading response header from upstream

修改nginx.conf文件中：

if ( !-e $request_filename)

{

proxy_pass http://127.0.0.1:8089;
}
