Windows安裝包：LibreOffice_7.0.6_Win_x64.msi

Linux(CentOs)安裝包：LibreOffice_7.0.6_Linux_x86-64_rpm.zip

安裝完成後，後續将使用java代碼調用軟體服務來提供word格式轉換

安裝

windows安裝：輕按兩下，點下一步…（安裝路徑不要含有中文）

Linux安裝

解壓上面資料的zip，得到兩個tar壓縮檔案，上傳至Linux

安裝

# 解壓
tar -zxvf LibreOffice_7.0.6_Linux_x86-64_rpm.tar.gz
tar -zxvf LibreOffice_7.0.6_Linux_x86-64_rpm_langpack_zh-CN.tar.gz

# 使用yum安裝rpm目錄裡的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添加環境變量
vim /etc/profile 
# 末尾追加
export LibreOffice_PATH=/opt/libreoffice7.0/program
export PATH=$LibreOffice_PATH:$PATH

# 使配置檔案生效
source /etc/profile

# 列印安裝路徑（下列代碼libreOfficePath填此值）
whereis libreoffice
