看下配置文件部分，是不是把 user 下面对应的代码块注释掉了？

#4

image
这一块 注释去掉。 或者 ssh 测试下 22端口 和admin账户密码

#5

是注释掉了，但是这块不是需要远程登录的时候才需要开启吗？后面我还是开启尝试了一下：

账号密码和端口都没有问题，注释去掉依旧报错

#7

你配置配置文件从哪里来的，单节点不需要做ssh操作，不需要输入用户名和密码 。
参考文章：
OceanBase 社区 。

单节点ip 直接写成127.0.0.1试试

https://github.com/oceanbase/obdeploy/blob/master/example/mini-local-example.yaml
ceanbase-ce:
  servers:
    # Please don't use hostname, only IP can be supported
    - 127.0.0.1
  global:
    #  The working directory for OceanBase Database. OceanBase Database is started under this directory. This is a required field.
    home_path: /root/observer //修改自己存储路径
    # The directory for data storage. The default value is $home_path/store.
    data_dir: /data/observer/data //修改自己存储路径
    # The directory for clog, ilog, and slog. The default value is the same as the data_dir value.
    redo_dir: /root/observer/redo //修改自己存储路径
     # please set memory limit to a suitable value which is matching resource. 
    memory_limit: 4G # The maximum running memory for an observer //observer进程占用内存，设置设置4G,因为新增租户增加到5G，在后续压测中还是内存提示租户内存不足，建议为至少6G。
    system_memory: 1G # The reserved system memory. system_memory is reserved for genera
#8

OK,感谢，更改之后可以安装的，我的配置文件在这里取的：https://github.com/oceanbase/obdeploy/blob/master/example/mini-single-example.yaml。
再问下，如果我还是需要这如下配置，我应该如何调整？
servers:
# Please don’t use hostname, only IP can be supported
- 192.168.100.30

#9

配置 192.168.100.30和应该没问题。这个没部署过。是不是网卡名字不对应，有的网卡名字不一定是eht0

 # if set severs as "127.0.0.1", please set devname as "lo"
    # if current ip is 192.168.1.10, and the ip's network adaptor's name is "eth0", please use "eth0"
    devname: eth0
#10

我的操作系统时候Red Hat 7.6，网卡就是enp0s17

#11

配置文件的global模块里增加这个参数
devname: enp0s17

    # Starting from observer version 4.2, the network selection for the observer is based on the 'local_ip' parameter, and the 'devname' parameter is no longer mandatory.
    # If the 'local_ip' parameter is set, the observer will first use this parameter for the configuration, regardless of the 'devname' parameter.
    # If only the 'devname' parameter is set, the observer will use the 'devname' parameter for the configuration.
    # If neither the 'devname' nor the 'local_ip' parameters are set, the 'local_ip' parameter will be automatically assigned the IP address configured above.

可以看下 obdeploy/example/mini-local-example.yaml at master · oceanbase/obdeploy · GitHub配置文件。
修改下配置文件看看。
单节点也可以试下这种方式： OBD DEMO 方式部署
