Tengine 的安装以及Tengine + Lua + GraphicsMagick 实现图片裁剪缩放

2015 / 08 / 29 nginx

测试安装Tengine

下载tengine

wget http://tengine.taobao.org/download/tengine-2.1.1.tar.gz

解压到当前目录

tar -zxvf tengine-2.1.1.tar.gz

进入tengine-2.1.1目录分别运行

$ ./configure
$ make
$ sudo make install

//Tengine默认将安装在/usr/local/nginx目录。你可以用'--prefix'来指定你想要的安装目录。

进入/usr/local/nginx 目录运行下面命令来显示所有编译的模块以及tenginx版本

./sbin/nginx -m

将nginx 添加到环境变量，然后重新ssh登录

vi /etc/profile
//末尾添加
export NGINX_HOME=/usr/local/nginx
export PATH=$NGINX_HOME/sbin:$PATH

启动nginx 停止nginx

sudo /usr/local/nginx/sbin/nginx
nginx -s stop
nginx -s reload //修改配置后重启

查看端口占用默认用的5012

netstat -anop|grep 5012

Tengine + Lua + GraphicsMagick 实现图片自动裁剪/缩放

所有步骤用的`root`用户操作,教程的centos版本

测试以及访问例子

丢了个文件到 QQphoto.jpeg , /home/keeley/document 里面做测试
访问原图片 http://192.168.xxx.xxx:81/QQphoto.jpeg
访问小图片http://192.168.xxx.xxx:81/QQphoto.jpeg_250x250.jpg
服务器如果发现没有会自动生成图片，然后下次就直接调用缓存获取了。

一些坑

1 找了很久发现5012总是出502错误，后来把5012端口改了就能成功访问了。改成了81

2 Tengine跟攻略不同的是去掉了安装参数 --with-openssl=/usr/local/src/openssl-1.0.1e,--with-zlib=/usr/local/src/zlib-1.2.8,这里本来想安装openssl的无奈一直出错就放弃了，观察了下后续也没用到这2个，就直接去掉了这2个参数

3 启动tengine同样出现了64位找不到jit的错误，使用了软连接

ln -s /usr/local/lib/libluajit-5.1.so.2 /lib64/libluajit-5.1.so.2

4 ImageResizer.lua 脚本，原版本//注释，然后执行切图的时候总是出错，后来去掉了就好了。

5 自己的图片目录/home/keeley/document 没有权限也会报错。后面赋权 chmod -R 777 . 就好了，能正常切图了。

6 测试发现的规律，会按等比例缩放，不会严格按照你设置的宽高，先从宽度开始，满足了符合的宽度，如果缩放之后高度也在设置的高度之内，就按缩放的高度算。如果缩放之后高度大于了设置的高度，就按高度算。所以实际是根据比例缩放，只有一边匹配，另一边少于设定值，如果完全。
