[已解决] 启动集群时找不到group_replication插件

我在openEuler上面容器部署GreatSql，使用的镜像是ccr.ccs.tencentyun.com/greatsql/greatsql:8.0.32-26。

启动容器后，我按照文档MGR安装部署的步骤启动集群。当执行到c.addInstance()添加另一个实例时，我选择Clone，然后就报错：
  1. ERROR: error installing plugin 'group_replication': 10.18.111.75:3306: Can't open shared library '/usr/lib/plugin/group_replication.so' (errno: 13 /usr/lib/plugin/group_replication.so: cannot open shared object file: No such file or directory)
  2. Cluster.addInstance: error installing plugin 'group_replication': 10.18.111.75:3306: Can't open shared library '/usr/lib/plugin/group_replication.so' (errno: 13 /usr/lib/plugin/group_replication.so: cannot open shared object file: No such file or directory) (RuntimeError)
复制代码
我看了下确实没有/usr/lib/plugin/这个目录。
我的my.cnf配置文件用的默认配置，几乎没有动过：

我想请教下这可能是什么原因导致的呢？

你问题中提到的文档适用于自行安装GreatSQL RPM包、二进制包的场景，而如果用GreatSQL Docker镜像构建MGR集群，可以参考这两份文档内容

- https://gitee.com/GreatSQL/Great ... B%E6%A8%A1%E5%BC%8F

- https://gitee.com/GreatSQL/Great ... B%E6%A8%A1%E5%BC%8F

你上面遇到的错误，估计是你在使用GreatSQL Docker部署时有些过程或方法不对导致的。

您说的部署的方法可能有问题，有哪些可能性呢？或者有什么步骤来排查一下呢？
我是按着这个文档Docker 容器化安装来部署的，mysql实例也能正常启动。容器启动命令稍微有所调整：
  1. docker run -d \
  2. --name greatsql --hostname=greatsql \
  3. --network=host \
  4. -v /root/mysql/my.cnf:/etc/my.cnf \
  5. -v /root/mysql/data:/data \
  6. ccr.ccs.tencentyun.com/greatsql/greatsql
复制代码

有可能是哪个路径配错了吗？或者是这些插件是通过网络下载的，然后我的网络有问题？

就是最上面那个。
然后，我其实几个月前就部署过一次，当时是没问题的。这次我是在新主机上重新拉镜像安装的，然后就出问题了。是不是镜像内容做了什么调整？

想起来了，前阵子我的确更新过，把原来用rpm方式安装的改成用tarball安装，所以要修改basedir，你重新pull镜像应该就好了，配置文件也要跟着更新，详见changelog：

- https://gitee.com/GreatSQL/Great ... 1abe4b9cbc8e92d4bad

现在，最新的GreatSQL 8.0.32-27也已经发布，建议用该版本

我看了下之前部署的容器，plugin_dir指向的是/usr/lib64/mysql/plugin/。
新的容器指向的是/usr/lib/plugin/。
是不是就是这个问题呢？

新容器的设置是
basedir=/usr/local/GreatSQL
那么plugin_dir即便不设置，则默认是/usr/local/GreatSQl/lib/plugin

顺便，我们有个问卷，还请抽空帮忙填一下哈，感谢 https://wj.qq.com/s2/11543483/9e09/
