tenginx+ImageMagick+Lua+FastDfs分布式自动缩略图
1.安装ImageMagick图片处理软件# tar xvf ImageMagick-6.4.0-0.tar.gz
# cd ImageMagick-6.4.0
# ./configure --prefix=/usr/local/ImageMagick-6.4.0
# make && make install
#
2.安装lua脚本语言
# yum install lua* -y
3.安装tenginx服务(必须先下载ngx_cache_purge和fastdfs-nginx-module模块)
# tar xvf tengine-2.1.0.tar.gz
# cd 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
# make -j4 && make install
# vim /usr/local/tenginx-2.1.0/conf/nginx.conf
server {
listen 800;
server_name localhost;
location / {
root html;
indexindex.html index.htm;
}
# /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)
# tar xvf fastdfs-5.04.tar.gz
# cd fastdfs-5.04
# ./make.sh
# ./make.sh install

# chkconfig --add fdfs_storaged
# 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
# 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+)/(+).(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, "(+)x(+)");
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 == 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/;
}
# /usr/local/tenginx-2.1.0/sbin/nginx -s reload
ngx_http_fastdfs_set pid=5233
#
6.在tracker节点上传图片
# fdfs_test /etc/fdfs/client.conf upload 26.jpg
