Mysqlrouter是官方下载，查看依赖关系

你这里所指的官方不是MySQL官方吗，为啥ldd查看的是GreatSQL目录下的mysqlrouter？
只看这个ldd结果的话，并不需要用到 http_auth_backend.so 动态库。
本贴最开始执行的 mysqlrouter 是什么路径下的，执行 which mysqlrouter 查看，然后对这个路径下的mysqlrouter 执行 ldd 查看动态库依赖关系。 yejr 发表于 2023-5-20 22:07

我不带路径参数，myrouter自动安装到 /usr/local/greatsql，真奇怪 qinxm 发表于 2023-5-21 07:52

从这个结果你也能看到了，GreatSQL目录下的mysqlrouter用ldd查看的话，并不需要用到 http_auth_backend.so 动态库。
你在运行mysqlrouter时却会报告这个错误，的确不好理解，请用strace之类的工具再跟踪看看。 yejr 发表于 2023-5-21 09:51
