linux系统上编译好的ImageMagick做迁移

如何把编译好的工具迁移到另一台机器上去,有时候我们会遇到这样的问题,怎样解决库文件的依赖问题就需要我们按照出错提示去解决问题了,我以ImageMagick为例做下讲解。


如何编译安装ImageMagick环境,参照我的上一篇文章ImageMagick的安装和使用案例,链接:


http://xiaoxiaozhou.blog.51cto.com/4681537/1903499


在本文中两台主机分别用server1和server2标识,server1为安装编译好ImageMagick的系统,server2则为未编译安装ImageMagick的系统。


首先把server1上编译好的文件传到server2上,下面为server2上已经接收到的文件

~/sxzhou> ll

total 40

drwxr-xr-x 7 was_wcm was_wcm  4096 Mar  3 10:30 ImageMagick

drwxr-xr-x 8 was_wcm was_wcm  4096 Mar  3 10:30 libpng-1.5.8


执行出错:

~/sxzhou/ImageMagick/bin> ./convert

./convert: error while loading shared libraries: libMagickCore-7.Q16HDRI.so.2: cannot open shared object file: No such file or directory


可以发现是库文件缺失,把缺失的库文件拷到server2上就可以了


server1上查找缺失的库文件

# find -name libMagickCore-7.Q16HDRI.so.2

./usr/local/ImageMagick/lib/libMagickCore-7.Q16HDRI.so.2

./home/sxzhouhou/ImageMagick-7.0.5-0/MagickCore/.libs/libMagickCore-7.Q16HDRI.so.2


可以发现除了安装目录下/usr/local/下也有库文件,拷贝/usr/local/ImageMagick到server2的/usr/local目录下


再次执行出错:

/home/was_wcm/sxzhou/ImageMagick/bin # ./convert

./convert: error while loading shared libraries: libpng15.so.15: cannot open shared object file: No such file or director


server1上查找

# find / -name libpng15.so.15

/usr/local/lib/libpng15.so.15

/home/sxzhouhou/libpng-1.5.8/.libs/libpng15.so.15


server1上png相关的库文件

/usr/local/lib # ls libpng

libpng.a  libpng.so  libpng15.la  libpng15.so.15  libpng.la  libpng15.a  libpng15.so libpng15.so.15.8.0  


拷贝server1上png相关的库文件到server2的/usr/local/lib/目录下


再次执行出错:

/home/was_wcm/sxzhou/ImageMagick/bin # ./convert

./convert: error while loading shared libraries: libpng15.so.15: cannot open shared object file: No such file or directory


/home/was_wcm/sxzhou/ImageMagick/bin # ldconfig /usr/local/lib

ldconfig: /usr/local/lib/libpng15.so.15 is not a symbolic link


出现上面的错误提示的原因是libpng15.so.15正常情况下是一个符号链接,所以修改其为符号链接即可


查看源主机的文件

/usr/local/lib # ll libpng15.so.15

lrwxrwxrwx 1 root root 18 Mar  2 14:21 libpng15.so.15 -> libpng15.so.15.8.0


而现主机文件

/usr/local/lib # ll libpng15.so.15

-rwxr-xr-x 1 root root 610183 Mar  3 10:44 libpng15.so.15


server2上做以下操作

/usr/local/lib # mv libpng15.so.15 libpng15.so.15.8.0

/usr/local/lib # ln -s libpng15.so.15.8.0 libpng15.so.15

/usr/local/lib # ll libpng15.so.15

lrwxrwxrwx 1 root root 18 Mar  3 10:59 libpng15.so.15 -> libpng15.so.15.8.0


终于可以使用了!!!
