目标主机100.98.1.123 为centos 7.8 ，已经安装docker，docker版本为
[root@cris_100 tmp]# docker version
Client:
Version: 20.10.9

将docker配置为普通用户admin可执行，仍然提示失败。
请大神们帮忙分析看看

#4

执行以下语句看下
（1）which docker
（2）docker --version
（3）systemctl status docker

或者指向下环境变量看看/etc/profile

看下这个环境变量

env|grep PATH

或建个软连接
docker命令软连接到/usr/bin/docker

目前通过软链接配置后，已经可以正常加载ocp镜像了，通过ocp的启动程序，可以看到ocp启动进程重新定义了一个PATH环境变量。
bash -c export PATH=/sbin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:$PATH; sudo docker run --rm --net=host --workdir=/home/admin/ocp-init/src/ocp-init --entrypoint=python -e PYTHONUNBUFFERED=1 -e TABLEGROUP_NAME=meta_database reg.docker.alibaba-inc.com/oceanbase/ocp-all-in-one:4.0.0-ce-bp1-20230119103000 …

好的，docker应该不是直接yum安装的吧，后续有问题可以再反馈。

#9

是的，docker 不是通过yum 或者rpm包安装的，通过binary的方式直接下载到指定目录，通过/etc/profile配置了环境变量的。

另外再请教下：我通过图形界面部署OCP的，密码都是正常输入，但是登录OCP平台的用户一直报错。请问ocp登录用户有默认密码的吗？还是说与部署的时候输入的密码一致的呢？

系统默认密码是：admin/system 用户的默认密码调整为了 aaAA11__ 这个吗？

#11

是的 admin/aaAA11__
