钨复制器4.0安装

Question

我正在尝试为MySQL5.7安装钨复制器4.0版本。我对MySQL5.7使用了二进制安装(tar.gz文件安装)，并在bash_profile中导出了路径。

./tools/tmp install命令已成功执行，但主服务和从服务均处于脱机状态。我们得到以下服务状态命令的错误信息。

[tungsten@beta-388 tungsten-replicator-4.0.0-18]$ /opt/continuent//tungsten/tungsten-replicator/bin/trepctl services

有人能分享一下如何解决这个错误吗？我已经多次尝试为该文件提供所有权限，还卸载并重新安装了钨。

Mysql 5.7版不支持钨4.0版，https://docs.continuent.com/tungsten-replicator-4.0/introduction.html
