PTK 在openEuler安装MogDB 报错 libreadline.so.7: cannot open shared object file

问题概述

执行安装过程中报错
[PTK-50000] execute error: init db: /mogdb/app/bin/gs_initdb: error while loading shared libraries: libreadline.so.7: cannot open shared object file: No such file or directory

问题原因

高版本openEuler中不存在libreadline.so.7文件

[root@PROD soft]# ldconfig -p | grep readline
libreadline.so.8 (libc6,x86-64) => /lib64/libreadline.so.8
libreadline.so (libc6,x86-64) => /lib64/libreadline.so
libguilereadline-v-18.so.18 (libc6,x86-64) => /lib64/libguilereadline-v-18.so.18
libguilereadline-v-18.so (libc6,x86-64) => /lib64/libguilereadline-v-18.so

[root@PROD soft]# cat /etc/os-release
NAME=“openEuler”
VERSION=“20.03 (LTS-SP3)”
ID=“openEuler”
VERSION_ID=“20.03”
PRETTY_NAME=“openEuler 20.03 (LTS-SP3)”
ANSI_COLOR=“0;31”

解决方案

建立软连接
