一样，自己的 vps ，账号也自己申请的，问第二次就会提示被限制

。。刚 ssh 断了，重连了下 cmake 命令就可以了。。。

@ysc3839 centos7

@8675bc86 在 cmake 的源码目录可以执行./bin/cmake --version

@seers /usr/local/bin 里没执行文件 path 里有 /usr/local/bin 路径

@Huelse 安装到 /usr/local/share 里了，但 ls 看不到 cmake 执行文件

@nekomiao 好的 谢谢
@xliao 谢谢 下次注意

@mango88 能获取 nacos 里的 java 服务配置，但里面不会有 ip ，也只是告诉你 openfeign 调用

@ajaxgoldfish 是要用 nacos 里的 其他 java 注册的服务

@xliao 不是要用 nacos ，是要用 nacos 里的 java 服务
