問題現象
ps -ef | grep yas 檢視無yasom和yasagent程序，且在{資料庫安裝目錄}/om/{資料庫名稱}的目錄下沒有conf、data、log等目錄，確定資料庫不是用yasboot安裝，是用指令碼安裝的
問題的風險及影響
非yasboot安裝，ycm無法完成託管，無法監控
問題影響的版本
不涉及ycm的版本問題
問題發生原因
資料庫版本太舊或安裝資料庫的人沒有按照規範使用yasboot安裝
解決方法及規避方式
將資料庫先託管到yasom中，再託管到ycm中
問題分析和處理過程
點選檢視程式碼
（1）生成配置檔案
-- ip必須是本機ip,install-path不能和安裝的資料庫path重重複
./bin/yasboot package config gen --cluster yasdb -u yashan -p Cod-2024 --ip 192.168.39.70 --install-path /home/yashan/yashandb/yasdb_yasom -t se
[yashan@KylinV10 yasdb_yasom]$ ./bin/yasboot package config gen --cluster yasdb -u yashan -p Cod-2024 --ip 192.168.39.70 --install-path /home/yashan/yashandb/yasdb_yasom -t se
192.168.39.70
192.168.39.70:1688 is already used
hostid | group | node_type | node_name | listen_addr | din_addr | replication_addr | data_path

（2）安裝yasom和yasagent
./bin/yasboot package install -i yashandb-22.2.3.0-linux-aarch64.tar.gz -t hosts.toml
[yashan@KylinV10 yasdb_yasom]$ ./bin/yasboot package install -i yashandb-22.2.3.0-linux-aarch64.tar.gz -t hosts.toml
checking install profile.toml...
install version: yashandb 22.2.3.0
update host to yasom...
[yashan@KylinV10 yasdb_yasom]$ ps -ef | grep yas

yashan 3955542 3950423 0 16:06 pts/1 00:00:00 ps -ef
yashan 3955543 3950423 0 16:06 pts/1 00:00:00 grep yas
（3）生成託管配置模版
./bin/yasboot package config join-demo -t SE

（4）修改託管配置模版
[yashan@KylinV10 yasdb_yasom]$ cat join_demo.toml
cluster = "tt"
sys_password = "yasdb_123"
yas_type = "SE"
[primary_config]
manage_ip = "127.0.0.1"
yasdb_home = "/opt/yasom/yashandb/tt"
node_path = "/opt/yasom/yashandb/data/tt/db-1-1"
node_id = "1-1:1"
[[standby_config]]
manage_ip = "127.0.0.1"
yasdb_home = "/opt/yasom/yashandb/tt"
node_path = "/opt/yasom/yashandb/data/tt/db-1-2"
node_id = "1-2:1"
[[standby_config]]
manage_ip = "127.0.0.1"
yasdb_home = "/opt/yasom/yashandb/tt"
node_path = "/opt/yasom/yashandb/data/tt/db-1-3"
node_id = "1-3:1"
修改後：
[yashan@KylinV10 yasdb_yasom]$ cat join_demo.toml
cluster = "yasdb"
sys_password = "yasdb_123"
yas_type = "SE"
[primary_config]
manage_ip = "192.168.39.70"
yasdb_home = "/home/yashan/yashandb/yasdb_home"
node_path = "/home/yashan/yashandb/yasdb_data"
node_id = "1-1:1"
（5）執行託管
./bin/yasboot cluster join -t SE --config join_demo.toml
[yashan@KylinV10 yasdb_yasom]$ ./bin/yasboot cluster join -t SE --config join_demo.toml
the cluster status is as follow:
|key |value
|------------+------
|clusterName |yasdb
|version |22.2.3.0
the cluster status is as follow:
hostid | node_type | nodeid | pid | instance_status | database_status | database_role | listen_address | data_path
-------------------------------------------------------------------------------------------------------------------------------------------------
host0001 | db | 1-1:1 | 3945392 | open | normal | primary | 0.0.0.0:1688 | /home/yashan/yashandb/yasdb_data
----------+-----------+--------+---------+-----------------+-----------------+---------------+----------------+----------------------------------
Check success
Are you sure you to add yasdb yasdb to yasom[yes/no]: yes
type | uuid | name | hostid | index | status | return_code | progress | cost
-------------------------------------------------------------------------------------------------------
task | eb0ecf155a0db5e6 | JoinYasdbCluster | - | yasdb | SUCCESS | 0 | 100 | -
------+------------------+------------------+--------+-------+---------+-------------+----------+------
task completed, status: SUCCESS
（6）檢視狀態
yashan@KylinV10 ~]$ yasboot cluster status -c yasdb -d
hostid | node_type | nodeid | pid | instance_status | database_status | database_role | listen_address | data_path
--------------------------------------------------------------------------------------------------------------------------------------------------------
host0001 | db | 1-1:1 | 3945392 | open | normal | primary | 0.0.0.0:1688 | /home/yashan/yashandb/data/yasdb/db-1-1
----------+-----------+--------+---------+-----------------+-----------------+---------------+----------------+-------------------------------
託管至yasom完成後，再按照流程託管至ycm即可
**經驗總結**
安裝資料庫要按照規範安裝，非規範安裝會導致一系列問題
