Nginx安装lua-nginx-module模块

原文地址

https://blog.csdn.net/qq_25551295/article/details/51744815

按上面地址基本可以配置成功，但是 lua-nginx-module v0.10.2.tar.gz 这个版本不能使用，改成了 v0.10.13.tar.gz 安装成功\

配合redis 使用，还需要安装扩展

安装redis-lua ，只需要复制到对应的安装目录

git clone https://github.com/nrk/redis-lua

cp redis-lua/src/redis.lua /usr/local/luajit/share/lua

安装lua-socket2.0.2

wget http://luaforge.net/frs/download.php/2664/luasocket-2.0.2.tar.gz

tar zxvf luasocket-2.0.2.tar.gz

cd luasocket-2.0.2

vim config

centos 安装CutyCapt

CutyCapt是一个截图工具官方网站 http://cutycapt.sourceforge.net/ 我主要的目的是解决用php保存网页为图片，废话不多少开始安装CutyCapt

yum install epel-release
 
#依赖安装
yum install Xvfb
yum install xorg-x11-fonts*
yum install qtwebkit-devel qt-devel
#中文字体
yum install fonts-chinese

yum install CutyCapt
#测试使用
xvfb-run --server-args="-screen 0, 1920x1080x24" CutyCapt --url=http://www.phpsong.com --out=phpsong.jpg

如果提示错误libEGL warning: DRI2: failed to open swrast (search paths /usr/lib64/dri)
解决方法

yum install mesa-dri-drivers

问题
1）截图时候有乱码
2) 执行速度慢
3）截取百度和小松博客，发现按钮上的文字没有显示,应该也是乱码导致的

PS.中文乱码问题
将windows下的中文字体上传至/usr/share/fonts目录，执行下命令fc-cache即可

测试截图

xvfb-run --server-args="-screen 0, 1920x1080x24" CutyCapt --url=http://www.phpsong.com --out=1.jpg
xvfb-run --server-args="-screen 0, 1920x1080x24" CutyCapt --url=http://www.baidu.com --out=2.jpg
xvfb-run --server-args="-screen 0, 1920x1080x24" CutyCapt --url=http://www.163.com --out=3.jpg
xvfb-run --server-args="-screen 0, 1920x1080x24" CutyCapt --url=http://www.sina.com.cn --out=4.jpg

PHP识别二维码的方法(php-zbarcode安装与使用)

说明：扩展需要依赖ImageMagick和zbar，安装前先安装这两个软件

yum install libgnomeui-devel

说明：扩展需要依赖ImageMagick和zbar，安装前先安装这两个软件

1.安装ImageMagick(http://www.imagemagick.org/)

1	`yum` `install` `ImageMagick.x86_64 ImageMagick-devel.x86_64`

2.安装zbar(http://sourceforge.net/projects/zbar/?source=directory)

wget http://jaist.dl.sourceforge.net/project/zbar/zbar/0.10/zbar-0.10.tar.bz2
tar jxvf zbar-0.10.tar.bz2
cd zbar-0.10
#注意此步有大坑，要禁止gtk,python和qt的支持，不然你就等着无限报错吧
./configure --without-gtk --without-python --without-qt --prefix=/usr/local/zbar
make && make install
#提示如下为完成，不是报错
#make[2]: Leaving directory `/root/zbar-0.10'
#make[1]: Leaving directory `/root/zbar-0.10'
#echo “/usr/local/zbar/lib/” >> /etc/ld.so.conf
 ldconfig
 ln -s /usr/local/zbar/lib/pkgconfig/zbar.pc /usr/lib64/pkgconfig/zbar.pc

3.安装php-zbarcode(https://github.com/mkoppanen/php-zbarcode)

unzip php-zbarcode-master.zip
cd php-zbarcode-master
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make && make install
#提示如下完成
#Build complete.
#Don't forget to run 'make test'.
#Installing shared extensions:   /usr/local/php/lib/php/extensions/no-debug-non-zts-20100525/

4.添加：extension=zbarcode.so 到php.ini配置文件

此时查看phpinfo();后搜索zbarcode后为完成

5.测试效果

图片取自https://en.wikipedia.org/wiki/File:Ean-13-5901234123457.png

另外，用户还可以使用本站二维码生成工具来生成二维码图片进行测试：
http://tools.jb51.net/transcoding/jb51qrcode

测试代码如下：

<?php
  //新建一个图像对象
  $image = new ZBarCodeImage("./test.png");
  // 创建一个二维码识别器
  $scanner = new ZBarCodeScanner();
  //识别图像
  $barcode = $scanner->scan($image);
  //循环输出二维码信息
  if (!empty($barcode)) {
    foreach ($barcode as $code) {
      printf("Found type %s barcode with data %s\n", $code['type'], $code['data']);
    }
  }
?>

百度云ssl证书安装

百度云免费证书申请成功之后，下载到以下三个文件

www.2898.com.cer

www.2898.com_ca.crt

www.2898.com.key

然后需要合并

cat static.2898.com.cer static.2898.com.cer > new.statice.2898.com.crt

编辑 new.statice.2898.com.crt

—–END CERTIFICATE———-BEGIN CERTIFICATE—–

把上面这行增加一个换行
