用自己压缩的mysql解压后，导入sql后安装程序报以下错误。找不到原因，同事用yum安装

的mariadb启动程序，却没有报错。

[ERROR][2020-06-11 18:23:28.068][http-nio-5001-exec-1][wsweb][2224][2224][LOG_POINT]Servlet.service() for servlet [dispatcherServlet] in context with path [/BaaS-Node-Manager] threw exception [Handler dispatch failed; nested exception is java.lang.InternalError: java.lang.reflect.InvocationTargetException] with root cause

后面发现安装一次mariadb后再卸载mariadb，再用自己压缩解压的数据库，导入sql然后程序就不报错了，不清楚什么原因，先记在这里，学无止境。

yum -y install mariadb
rpm -qa|grep mariadb
rpm -e --nodeps mariadb-libs-5.5.65-1.el7.x86_64 mariadb-server-5.5.65-1.el7.x86_64 mariadb-5.5.65-1.el7.x86_64 mariadb-embedded-5.5.65-1.el7.x86_64 mariadb-test-5.5.65-1.el7.x86_64 mariadb-embedded-devel-5.5.65-1.el7.x86_64 mariadb-devel-5.5.65-1.el7.x86_64 mariadb-bench-5.5.65-1.el7.x86_64
