## 相关资料 ##

Windows安装包：[LibreOffice\_7.0.6\_Win\_x64.msi][LibreOffice_7.0.6_Win_x64.msi]  
Linux(CentOs)安装包：[LibreOffice\_7.0.6\_Linux\_x86-64\_rpm.zip][LibreOffice_7.0.6_Linux_x86-64_rpm.zip]

> 安装完成后，后续将使用java代码调用软件服务来提供word格式转换

    tar -zxvf LibreOffice_7.0.6_Linux_x86-64_rpm_langpack_zh-CN.tar.gz
    
    # 使用yum安装rpm目录里的rpm
    yum install LibreOffice_7.0.6.2_Linux_x86-64_rpm/RPMS/*.rpm -y
    yum install LibreOffice_7.0.6.2_Linux_x86-64_rpm_langpack_zh-CN/RPMS/*.rpm -y
    
    # 修改profile添加环境变量
    vim /etc/profile 
    # 末尾追加
    export LibreOffice_PATH=/opt/libreoffice7.0/program
    export PATH=$LibreOffice_PATH:$PATH
    
    # 使配置文件生效
    source /etc/profile
    
    # 打印安装路径（下列代码libreOfficePath填此值）
    whereis libreoffice
    
    soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard
