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，如下
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：
#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 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_set_header Host 127.0.0.1;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

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;
}
