observer 和obproxy-ce 密码是注释掉不行,开启后输入密码也不行。

Only need to configure when remote login is required

user:

username: your username

password: your password if need

key_file: your ssh-key file path if need

port: your ssh port, default 22

timeout: ssh connection timeout (second), default 30

In this example , support multiple ob process in single node, so different process use different ports.

If deploy ob cluster in multiple nodes, the port and path setting can be same.

server1:
mysql_port: 2881 # External port for OceanBase Database. The default value is 2881. DO NOT change this value after the cluster is started.
rpc_port: 2882 # Internal port for OceanBase Database. The default value is 2882. DO NOT change this value after the cluster is started.
# The working directory for OceanBase Database. OceanBase Database is started under this directory. This is a required field.
home_path: /root/observer
# The directory for data storage. The default value is $home_path/store.
# data_dir: /data
# The directory for clog, ilog, and slog. The default value is the same as the data_dir value.
# redo_dir: /redo
zone: zone1
server2:
mysql_port: 2881 # External port for OceanBase Database. The default value is 2881. DO NOT change this value after the cluster is started.
rpc_port: 2882 # Internal port for OceanBase Database. The default value is 2882. DO NOT change this value after the cluster is started.
# The working directory for OceanBase Database. OceanBase Database is started under this directory. This is a required field.
home_path: /root/observer
# The directory for data storage. The default value is $home_path/store.
# data_dir: /data
# The directory for clog, ilog, and slog. The default value is the same as the data_dir value.
# redo_dir: /redo
zone: zone2
server3:
mysql_port: 2881 # External port for OceanBase Database. The default value is 2881. DO NOT change this value after the cluster is started.
rpc_port: 2882 # Internal port for OceanBase Database. The default value is 2882. DO NOT change this value after the cluster is started.

Set dependent components for the component.

When the associated configurations are not done, OBD will automatically get the these configurations from the dependent components.

depends:
- oceanbase-ce
servers:

global:
listen_port: 2883 # External port. The default value is 2883.
prometheus_listen_port: 2884 # The Prometheus port. The default value is 2884.
home_path: /root/obproxy

# cluster_name: obcluster
skip_proxy_sys_private_check: true
enable_strict_kernel_release: false
# obproxy_sys_password: # obproxy sys user password, can be empty. When a depends exists, OBD gets this value from the oceanbase-ce of the depends.
# observer_sys_password: # proxyro user pasword, consistent with oceanbase-ce’s proxyro_password, can be empty. When a depends exists, OBD gets this value from the oceanbase-ce of the depends.

报错的地方是ssh模块,可以打开user模块,配置上用户和密码或key信息,节点之间做对应用户的互信。

好的,感谢大佬,是ssh密码密改了,导致不能互信了,删除ssh互信文件,后重新安装ssh互信文件
