为 AWS linux 安装 Tesseract

Question

如何在 AWS Linux 中安装 Tesseract？几个月前，我们的一名团队成员尝试了以下命令。

cd /opt
mkdir tesseract
chmod 0755 tesseract
cd tesseract

yum install libpng-devel
yum install libtiff-devel
yum install libjpeg-devel
wget http://www.leptonica.com/source/leptonica-1.71.tar.gz 
tar xzf leptonica-1.71.tar.gz
cd leptonica-1.71
./configure
make
make install
export LIBLEPT_HEADERSDIR=/usr/local/include # Add to .profile

cd /opt/tesseract
yum install libtool
wget https://tesseract-ocr.googlecode.com/files/tesseract-ocr-3.02.02.tar.gz
tar xzf tesseract-ocr-3.02.02.tar.gz # Makes tesseract-ocr directory, no version.
cd tesseract-ocr
./autogen.sh
./configure --with-extra-libraries=/opt/tesseract
make
sudo make install
sudo ldconfig

cd /opt/tesseract
wget https://tesseract-ocr.googlecode.com/files/tesseract-ocr-3.02.eng.tar.gz
tar xzf tesseract-ocr-3.02.eng.tar.gz # Makes tesseract-ocr/tessdata directory.
sudo cp ./tessdata/* /usr/local/share/tessdata/ | for each
$>rm –rf tessdata 
export TESSDATA_PREFIX=/opt/tesseract/tesseract-ocr/

但是这些命令没有帮助。当我们为 PHP运行Tesseract OCR 时，出现以下错误。

错误！未找到命令“tesseract”。确保您的系统上安装了 Tesseract OCR

如果有人分享任何教程/文档链接会很有帮助。

这应该适用于 Amazon Linux 2：

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
yum -y update
yum -y install tesseract
