1.安装ImageMagick图片处理软件

[root@node2 ~]# tar xvf ImageMagick-6.4.0-0.tar.gz 

[root@node2 ~]# cd ImageMagick-6.4.0

[root@node2 ImageMagick-6.4.0]# ./configure --prefix=/usr/local/ImageMagick-6.4.0

[root@node2 ImageMagick-6.4.0]# make && make install

[root@node2 ImageMagick-6.4.0]#


2.安装lua脚本语言

[root@node2 ~]# yum install lua* -y


3.安装tenginx服务(必须先下载ngx_cache_purge和fastdfs-nginx-module模块)

[root@node2 ~]# tar xvf tengine-2.1.0.tar.gz

[root@node2 ~]# cd tengine-2.1.0

[root@node2 tengine-2.1.0]#  --prefix=/usr/local/tenginx-2.1.0 --with-file-aio --with-poll_module --with-pcre=/usr/local/pcre-8.37 --without-http_autoindex_module --without-http_ssi_module --without-maingx_cache_purgel_pop3_module --without-mail_smtp_module --without-mail_imap_module --with-http_lua_module --with-ld-opt=-Wl,-rpath,/usr/local/lib --with-http_realip_module --with-http_concat_module --add-module=/root/ngx_cache_purge-1.6 --add-module=/root/fastdfs-nginx-module/src

[root@node2 tengine-2.1.0]# make -j4 && make install

[root@node2 tengine-2.1.0]# vim /usr/local/tenginx-2.1.0/conf/nginx.conf

server {

  listen 800;

  server_name localhost;

  location / {

     root html  ;

     index  index.html index.htm;

  }

[root@node2 tengine-2.1.0]# /usr/local/tenginx-2.1.0/sbin/nginx

4.安装fastDFS分布式文件系统

fastDFS必须有三个节点,一个tracker节点,两个storage节点.tracker节点是管理,监控,维护两个数据节点,文件上传.storage数据节点是做文件存储,校验,容灾.tenginx必须装在storage节点上.

node1节点:(tracker节点)

[root@node1 ~]# tar xvf fastdfs-5.04.tar.gz 

[root@node1 ~]# cd fastdfs-5.04

[root@node1 fastdfs-5.04]# ./make.sh 

[root@node1 fastdfs-5.04]# ./make.sh install

[root@node1 ~]# vim /etc/fdfs/tracker.conf 

[root@node1 ~]# egrep -v ‘^#|^$‘ /etc/fdfs/tracker.conf

http.check_alive_interval=30

http.check_alive_type=tcp

http.check_alive_uri=/status.html

[root@node1 ~]# egrep -v ‘^#|^$‘ /etc/fdfs/client.conf 

connect_timeout=30

[root@node2 ~]# cd fastdfs-5.04

[root@node2 fastdfs-5.04]# ./make.sh

[root@node2 fastdfs-5.04]# cd 

[root@node2 ~]# tar xvf fastdfs-nginx-module_v1.16.tar.gz  --加载fastdfs-nginx-module模块配置文件

[root@node2 ~]# cp -a fastdfs-nginx-module/src/mod_fastdfs.conf  /etc/fdfs/

[root@node2 ~]# cp fastdfs-5.04/init.d/fdfs_storaged  /etc/init.d/

[root@node2 ~]# chkconfig --add fdfs_storaged

[root@node2 ~]# chkconfig fdfs_storaged on

node3同node2配置是一样的,只是绑定的IP不一样而已


5.在storage节点1上修改tenginx的配置文件

[root@node2 ~]# vim /usr/local/tenginx-2.1.0/conf/nginx.conf

server {

  listen 800;

  server_name localhost;

  location /lua {

     default_type ‘text/plain‘;

     content_by_lua ‘ngx.say("hello,lua")‘;

     }

  location ~* /group1/M00/  {

      ngx_fastdfs_module;

      set $needCreateImg 0;

      if ( !-f $request_filename) {

         set $needCreateImg "${needCreateImg}1";

      }


     if ($uri ~* "/group1/M00/(\d+)/(\d+)/([A-Za-z0-9_-]+).(gif|jpg|jpeg|png).(\d+x\d+).(gif|jpg|jpeg|png)") {

         set $needCreateImg "${needCreateImg}2";

         set $conUri     "/$1/$2/$3.$4.$5.$6";

      }


      if ($needCreateImg = "012") {

         set $image_root "/home/fastdfs/data";

         set $file "$image_root$conUri";

            rewrite_by_lua ‘

               local index = string.find(ngx.var.conUri, "([0-9]+)x([0-9]+)");

               local originalUri = string.sub(ngx.var.conUri, 0, index-2);

               local area = string.sub(ngx.var.conUri, index);

               index = string.find(area, "([.])");

               area = string.sub(area, 0, index-1);


               function table.contains(table, element)

                 for _, value in pairs(table) do                 

                   if value =http://www.mamicode.com/= element then

                     return true

                   end

                  end

                  return false

                end


                local c = "/usr/local/GraphicsMagick-1.3.23/bin/gm convert " .. ngx.var.image_root ..  originalUri  .. " -thumbnail " .. area .. " - ";

                local f = assert(io.popen(c, "r"))

                local s = assert(f:read("*a"))

                f:close()

                ngx.say(s) ‘;

              }

           alias /home/fastdfs/data/;

        }

[root@node2 ~]# /usr/local/tenginx-2.1.0/sbin/nginx -s reload

ngx_http_fastdfs_set pid=5233

[root@node2 ~]# 


6.在tracker节点上传图片

[root@node2 ~]# fdfs_test /etc/fdfs/client.conf upload 26.jpg
