案例说明：
在UOS系统下部署KingbaseES V8R6数据库时，出现Java错误，部署失败。
系统版本：
kingbase@srv01:~$ cat /etc/os-release
PRETTY_NAME="UnionTech OS Server 20 "
NAME="UnionTech OS Server 20 "
VERSION_ID="20"
VERSION="20"
ID=UOS
HOME_URL="https://www.chinauos.com/"
BUG_REPORT_URL="http://bbs.chinauos.com"
VERSION_CODENAME=fou
数据库版本：
KingbaseES V8R6
一、问题现象
如下图所示，在执行部署时出现以下java故障：
执行部署：
kingbase@srv01:/mnt$ sh setup.sh

Complete.
二、问题分析
1、查看系统java版本
kingbase@srv01:/mnt$ java -version
openjdk version "11.0.9.1" 2020-11-04
OpenJDK Runtime Environment (build 11.0.9.1+1-post-Uos-1deb10u2)
OpenJDK 64-Bit Server VM (build 11.0.9.1+1-post-Uos-1deb10u2, mixed mode)
2、升级java版本
下载java二进制版本后，解压，配置/etc/profile:
#java conf
export JAVA_HOME=/deepin/userdata/opt/jdk-22
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib:$CLASSPATH
export JAVA_PATH=${JAVA_HOME}/bin:${JRE_HOME}/bin
export PATH=${JAVA_PATH}:$PATH
JAVA 版本：
kingbase@srv01:~$ java -version
openjdk version "22" 2024-03-19
OpenJDK Runtime Environment (build 22+36-2370)
OpenJDK 64-Bit Server VM (build 22+36-2370, mixed mode, sharing)
3、执行部署
如下图所示，故障依旧：
4、查看数据库用户kingbase属性
如下所示，kingbase用户的宿主目录是root：
kingbase@srv01:~$ ls -lhd /home/kingbase/
drwxr-xr-x 30 root root 4.0K 4月 8 11:27 /home/kingbase/
修改宿主目录所有者：
kingbase@srv01:~$ ls -lhd /home/kingbase/
drwxr-xr-x 30 kingbase kingbase 4.0K 4月 8 11:27 /home/kingbase/
5、重新部署，部署成功！
三、问题总结
从以上操作可知，此问题应该和java版本没有关系，是数据库用户的属主问题导致，无法正常访问java环境。
