# 配置变更

## 简介

ChainMaker在部署完成后，默认生成的链配置文件目录为：安装目录/config/orgid/chainconfig/bcx.yml，文件名bcx.ym代表链id。在ChainMker启动时会使用链配置文件生成创世配置块，后续如果想更改链配置就需要使用动态配置更改的方式进行。



## 配置更改的方式

当前链配置的更改可以使用ChainMaker的命令行工具cmc进行，当前cmc支持的链配置功能有限，更多配置的更改需要使用chainmaker的go语言或java语言的sdk编写客户端代码进行更改。具体参考

[SDK.md]: ../dev/SDK.md



## 使用命令行工具修改链配置

- 查询链配置

```sh
./cmc client chainconfig query \
--sdk-conf-path=./testdata/sdk_config.yml \
--org-id=wx-org1.chainmaker.org \
--client-crt-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/client1/client1.tls.crt \
--client-key-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/client1/client1.tls.key
```

- 更新区块出块时间

```sh
./cmc client chainconfig block updateblockinterval \
--org-id=wx-org1.chainmaker.org \
--client-crt-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/client1/client1.tls.crt \
--client-key-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/client1/client1.tls.key \
--sdk-conf-path=./testdata/sdk_config.yml \
--admin-crt-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/admin1/admin1.tls.crt \
--admin-key-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/admin1/admin1.tls.key \
--block-interval 1000
```

- 增加组织根证书

```sh
./cmc client chainconfig trustroot add \
--org-id=wx-org1.chainmaker.org \
--client-crt-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/client1/client1.tls.crt \
--client-key-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/client1/client1.tls.key \
--sdk-conf-path=./testdata/sdk_config.yml \
--admin-crt-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/admin1/admin1.tls.crt \
--admin-key-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/admin1/admin1.tls.key \
--trust-root-org-id=wx-org5.chainmaker.org \
--trust-root-path=./testdata/crypto-config/wx-org5.chainmaker.org/ca/ca.crt
```

- 删除组织根证书

```sh
./cmc client chainconfig trustroot add \
--org-id=wx-org1.chainmaker.org \
--client-crt-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/client1/client1.tls.crt \
--client-key-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/client1/client1.tls.key \
--sdk-conf-path=./testdata/sdk_config.yml \
--admin-crt-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/admin1/admin1.tls.crt \
--admin-key-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/admin1/admin1.tls.key \
--trust-root-org-id=wx-org5.chainmaker.org \
--trust-root-path=./testdata/crypto-config/wx-org5.chainmaker.org/ca/ca.crt
```

- 升级组织根证书

```sh
./cmc client chainconfig trustroot add \
--org-id=wx-org1.chainmaker.org \
--client-crt-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/client1/client1.tls.crt \
--client-key-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/client1/client1.tls.key \
--sdk-conf-path=./testdata/sdk_config.yml \
--admin-crt-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/admin1/admin1.tls.crt \
--admin-key-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/admin1/admin1.tls.key \
--trust-root-org-id=wx-org5.chainmaker.org \
--trust-root-path=./testdata/crypto-config/wx-org5.chainmaker.org/ca/ca.crt
```

- 添加共识节点

```sh
./cmc client chainconfig consensusnode add \
--org-id=wx-org1.chainmaker.org \
--client-crt-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/client1/client1.tls.crt \
--client-key-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/client1/client1.tls.key \
--sdk-conf-path=./testdata/sdk_config.yml \
--admin-crt-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/admin1/admin1.tls.crt \
--admin-key-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/admin1/admin1.tls.key \
--node-id=QmcQHCuAXaFkbcsPUj7e37hXXfZ9DdN7bozseo5oX4qiC4 \
--node-org-id=wx-org1.chainmaker.org
```

- 删除共识节点

```sh
./cmc client chainconfig consensusnode remove \
--org-id=wx-org1.chainmaker.org \
--client-crt-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/client1/client1.tls.crt \
--client-key-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/client1/client1.tls.key \
--sdk-conf-path=./testdata/sdk_config.yml \
--admin-crt-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/admin1/admin1.tls.crt \
--admin-key-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/admin1/admin1.tls.key \
--node-id=QmcQHCuAXaFkbcsPUj7e37hXXfZ9DdN7bozseo5oX4qiC4 \
--node-org-id=wx-org1.chainmaker.org
```



- 升级共识节点

```sh
./cmc client chainconfig consensusnode update \
--org-id=wx-org1.chainmaker.org \
--client-crt-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/client1/client1.tls.crt \
--client-key-file-paths=./testdata/crypto-config/wx-org1.chainmaker.org/user/client1/client1.tls.key \
--sdk-conf-path=./testdata/sdk_config.yml \
