openoffice命令行方式将word、excel、ppt转成pdf

上一篇记录了安装libreoffice的方式将office文档转换成pdf，接下来将使用openoffice实现同样的功能。

首先到openoffice官网下载最新的rpm压缩包：

https://www.openoffice.org/download/index.html

目前我下载最的的是：Apache_OpenOffice_4.1.3_Linux_x86-64_install-rpm_zh-CN.tar.gz

解压并进入到相关目录安装rpm包：

[root@instance-32spzihn src]# tar -zxvf Apache_OpenOffice_4.1.3_Linux_x86-64_install-rpm_zh-CN.tar.gz
[root@instance-32spzihn src]# cd zh-CN/RPMS
[root@instance-32spzihn RPMS]# yum install *.rpm
[root@instance-32spzihn RPMS]# cd /opt/openoffice4/program

安装完成并进入到对应的program目录之后，启动openoffice：

[root@instance-32spzihn program]# ./soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard &

发现报错：

[root@instance-32spzihn program]# javaldx: Could not find a Java Runtime Environment!

不过openoffice服务已经启动，由于只需要用到转换接口命令，不影响功能的情况下，我就不深究了。

接下来就需要一份python的脚本程序，因为转换需要通过py程序去调用api处理，将下面程序保存到topdf.py文件：

将文件保存到program目录下面，然后就可以执行转换命令了：

[root@instance-32spzihn program]# ./python topdf.py zzz.docx zzz_1.pdf

同样的命令也可以转换其它格式的文件，如：

[root@instance-32spzihn program]# ./python topdf.py zzz.docx zzz_1.html

相对来说，libreoffice实现起来要比openoffice要简单点，转换效果差不多，若转换中文文档乱码，请参数libreoffice的字体部分。
