【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
