在openEuler22.03sp3上安装openEuler企业版5.0.1LTS，影响root用户正常使用yum和dnf

【标题描述】:在openEuler22.03sp3上安装openEuler企业版5.0.1LTS，影响root用户正常使用yum和dnf

【测试类型：工具功能】【测试版本：5.0.1】 问题描述

【操作系统和硬件信息】(查询命令: cat /etc/system-release, uname -a):
5.10.0-182.0.0.95.oe2203sp3.x86_64
【测试环境】(单机/1主x备x级联备):
单机
【被测功能】:
安装
【测试类型】:

【数据库版本】(查询命令: gaussdb -V):
gaussdb (openGauss 5.0.1 build 33b035fd) compiled at 2023-12-15 19:51:49 commit 0 last mr

【预置条件】:

【操作步骤】(请填写详细的操作步骤):
1. 按照官网文档安装openGauss5.0.1LTS企业版
2. openGauss正常启动后能正常使用
3.回到root用户，使用yum和dnf命令均报错，安装前无此问题

【预期输出】:能够打印出yum和dnf命令的可选参数

【实际输出】:报错

【原因分析】:
1. 这个问题的根因：在/etc/profile中修改了一些影响yum和dnf的LD_LIBRARY_PATH变量
2. 问题推断过程：看报错提示猜的
3. 还有哪些原因可能造成类似现象：无
4. 该问题是否有临时规避措施：临时注释/etc/profile中修改的LD_LIBRARY_PATH变量并重启系统
5. 问题解决方案
6. 预计修复问题时间

【日志信息】(请附上日志文件、截图、coredump信息):

用虚拟机验证过了，source /etc/profile还是不能用，只能重启。
