【YashanDB知识库】ycm托管数据库时，数据库非OM安装无法托管

问题现象

ps -ef | grep yas 查看无yasom和yasagent进程，且在{数据库安装目录}/om/{数据库名称}的目录下没有conf、data、log等目录，确定数据库不是用yasboot安装，是用脚本安装的

问题的风险及影响

非yasboot安装，ycm无法完成托管，无法监控

问题影响的版本

不涉及ycm的版本问题

问题发生原因

数据库版本太旧或安装数据库的人没有按照规范使用yasboot安装

解决方法及规避方式

将数据库先托管到yasom中，再托管到ycm中

问题分析和处理过程

（1）生成配置文件
-- ip必须是本机ip,install-path不能和安装的数据库path重重复
./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
--------------------------------------------------------------------------------------------------------------------------------------------------------
 host0001 | dbg1  | db        | 1-1       | 192.168.39.70:1688 | 192.168.39.70:1689 | 192.168.39.70:1690 | /home/yashan/yashandb/yasdb_yasom/data/yasdb
----------+-------+-----------+-----------+--------------------+--------------------+--------------------+----------------------------------------------

Generate config success

（2）安装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   3945392       1  0 15:04 ?        00:00:25 yasdb open -D /home/yashan/yashandb/yasdb_data
root     3950422 3950243  0 15:37 pts/1    00:00:00 su - yashan
yashan   3950423 3950422  0 15:37 pts/1    00:00:00 -bash
root     3953443 3952376  0 15:49 pts/2    00:00:00 su - yashan
yashan   3953444 3953443  0 15:49 pts/2    00:00:00 -bash
yashan   3955488       1  0 16:05 ?        00:00:00 /home/yashan/yashandb/yasdb_yasom/bin/yasagent --init -c yasdb -l 192.168.39.70:1676 --host-id host0001 -k 564e9e581348c9ae -d
yashan   3955503       1  0 16:06 ?        00:00:00 /home/yashan/yashandb/yasdb_yasom/bin/yasom --init -c yasdb -l 192.168.39.70:1675 -k 564e9e581348c9ae -d
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）生成托管配置模版
./bin/yasboot package config join-demo -t SE

[yashan@KylinV10 yasdb_yasom]$ ./bin/yasboot package config join-demo -t SE
[yashan@KylinV10 yasdb_yasom]$ ll

（4）修改托管配置模版
[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"

修改后：

[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）执行托管
./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）查看状态
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
----------+-----------+--------+---------+-----------------+-----------------+---------------+----------------+-----------------------------------------

托管至yasom完成后，再按照流程托管至ycm即可

经验总结

安装数据库要按照规范安装，非规范安装会导致一系列问题
