centOS 7.9安装了oracledb_export后启动服务报错

刘泽宇

现象：
Centos7.9服务器上安装了用于监控Oracle数据库的oracledb_exporter，但在启动服务的时候显示服务启动失败，检查报错为：
-- Unit oracledb_exporter@orcl.service has finished starting up.
-- -- The start-up result is done.

原因：
oracledb_exporter 程序要求更高版本的 GLIBC 2.34
而Centos7.9上的GLIBC版本为2.17
同时GLIBC不建议随意升级
因此确定Centos 7.9版本无法使用oracledb_exporter进行oracle数据库的监控
