暫做筆記，帶后續(xù)驗證通過后，再補充 1、2、3 步。
一、安裝 lua
首先確認是否安裝 readline
yum -y install readline-devel ncurses-devel
進入頁面：http://www.lua.org/download.html
wget http://www.lua.org/ftp/lua-5.3.1.tar.gz tar zxvf lua-5.3.1.tar.gz #進入解壓目錄make linux && make install
wget http://luajit.org/download/LuaJIT-2.0.4.tar.gztar zxvf LuaJIT-2.0.4.tar.gz cd LuaJIT-2.0.4make && make install
ln -s /usr/local/lib/libluajit-5.1.so.2 /lib64/libluajit-5.1.so.2export LUAJIT_LIB=/usr/local/libexport LUAJIT_INC=/usr/local/include/luajit-2.0/
二、安裝 GraphicsMagick
進入頁面：http://www.graphicsmagick.org/1.3/download.html
tar zxvf GraphicsMagick-1.3.21.tar.gzcd GraphicsMagick-1.3.21./configure --prefix=/usr/local/graphicsmagick
make && make install
#驗證
/usr/local/graphicsmagick/bin/gm version
三、安裝nginx
進入頁面：http://tengine.taobao.org/opensource_cn.html
./configure --prefix=/usr/local/nginx --dso-path=/usr/local/nginx/modules --with-http_realip_module --with-http_gzip_static_module --with-http_stub_status_module --with-http_concat_module --with-http_lua_module --with-pcre=/usr/local/src/pcre-8.37 --with-zlib=/usr/local/src/zlib-1.2.8 --with-openssl=/usr/local/src/openssl-1.0.0s --http-proxy-temp-path=/var/tmp/nginx/proxy_temp --http-fastcgi-temp-path=/var/tmp/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi_temp --http-scgi-temp-path=/var/tmp/nginx/cgi_temp --http-client-body-temp-path=/var/tmp/nginx/client_body_temp --http-log-path=/var/log/nginx/access.log --error-log-path=/var/log/nginx/error.log --with-ld-opt="-Wl,-rpath,$LUAJIT_LIB"make && make install#啟動nginx#測試配置文件 /usr/local/nginx/sbin/nginx -t#啟動/usr/local/nginx/sbin/nginx
設置開機啟動
vi /etc/rc.d/init.d/nginx
#!/bin/bash# Tengine Startup script# processname: nginx# chkconfig: - 85 15# description: nginx is a World Wide Web server.

保存退出
chmod 775 /etc/rc.d/init.d/nginx #賦予文件執(zhí)行權限chkconfig --level 012345 nginx on #設置開機啟動service nginx start
四、配置 nginx
nginx.conf
http { lua_package_path '/usr/local/openresty/nginx/lua/?.lua;;'; server { listen 80; server_name img.rhythmk.org; root /home/wwwroot/static/image; #對類似_100x100.gif/jpg/png/jpeg進行縮略圖處理 location ~* _([0-9]+)x([0-9]+)\.(gif|jpg|png|jpeg)$ { #匹配文件名規(guī)則 root /home/wwwroot/static/image; #站點根目錄 set $image_root /home/wwwroot/static/image; #圖片目錄 set $thumbnail_root /home/wwwroot/static/thumbnail; #縮略圖存放目錄 #如果縮略圖文件存在，直接返回 set $file $thumbnail_root$uri; if (-f $file) { rewrite ^/(.*)$ /thumbnail/$1 last; } #如果縮略圖文件不存在，則應用縮略圖模塊處理 if (!-f $file) { rewrite_by_lua_file lua/thumbnail.lua; } } } #include conf/*.conf;}lua/thumbnail.lua
local index = string.find(ngx.var.uri, "([0-9]+)x([0-9]+)"); local originalUri = string.sub(ngx.var.uri, 0, index-2); local area = string.sub(ngx.var.uri, index); index = string.find(area, "([.])"); area = string.sub(area, 0, index-1); local image_sizes = {"80x80", "800x600", "40x40"}; function table.contains(table, element) for _, value in pairs(table) do if value == element then return true end end return false end if table.contains(image_sizes, area) then local command = "gm convert " .. ngx.var.image_root .. originalUri .. " -thumbnail " .. area .. " -background gray -gravity center -extent " .. area .. " " .. ngx.var.file; os.execute(command); ngx.req.set_uri(ngx.var.uri, true); else ngx.exit(404); end;
