分布式存储
安装MySQL
当前支持的分布式数据库是MySQL,在使用分布式存储之前,需要先搭建MySQL服务,在Ubuntu和CentOS服务器上的配置方式如下:
Ubuntu:执行下面三条命令,安装过程中,配置 root 账户密码。
sudo apt install -y mysql-server mysql-client libmysqlclient-dev
启动 MySQL 服务并登陆: root 账户密码。
service msyql start
mysql -uroot -p
CentOS: 执行下面两条命令进行安装。
yum install mysql*
#某些版本的linux,需要安装mariadb,mariadb是mysql的一个分支
yum install mariadb*
启动 MySQL 服务,登陆并为 root 用户设置密码。
service mysqld start
#若安装了mariadb,则使用下面的命令启动
service mariadb start
mysql -uroot -p
mysql> set password for root@localhost = password('123456');
配置MySQL参数
查看配置文件my.cnf
mysql --help | grep 'Default options' -A 1
执行之后可以看到如下如下数据
Default options are read from the following files in the given order:
/etc/mysql/my.cnf /etc/my.cnf ~/.my.cnf
配置my.cnf
mysql依次从/etc/mysql/my.cnf,/etc/my.cnf,~/.my.cnf中加载配置。依次查找这几个文件,找到第一个存在的文件,在[mysqld]段中新增如下内容(如果存在则修改值)。
max_allowed_packet = 1024M
sql_mode =STRICT_TRANS_TABLES
重启mysql-sever,验证参数。
Ubuntu:执行如下命令重启
service mysql restart
CentOS:执行如下命令重启
service mysqld start
#若安装了mariadb,则使用下面的命令启动
service mariadb start
验证参数过程
mysql -uroot -p
#执行下面命令,查看max_allowed_packet的值
MariaDB [(none)]> show variables like 'max_allowed_packet%';
+--------------------+------------+
| Variable_name | Value |
+--------------------+------------+
| max_allowed_packet | 1073741824 |
+--------------------+------------+
1 row in set (0.00 sec)
#执行下面命令,查看sql_mode的值
MariaDB [(none)]> show variables like 'sql_mode%';
+---------------+---------------------+
| Variable_name | Value |
+---------------+---------------------+
| sql_mode | STRICT_TRANS_TABLES |
+---------------+---------------------+
1 row in set (0.00 sec)
节点直连MySQL
FISCO BCOS在2.0.0-rc3之后,支持节点通过连接池直连MySQL,相对于代理访问MySQL方式,配置简单,不需要手动创建数据库。配置方法请参考:
逻辑架构图
多群组架构是指区块链节点支持启动多个群组,群组间交易处理、数据存储、区块共识相互隔离的。因此群组下的每一个节点对应一个数据库实例,例如,区块链网络中,有三个节点A,B,C,其中A,B属于Group1,B,C属于Group2。节点A和C分别对应1个数据库实例,B节点对应了2个数据库实例,逻辑架构图如下 如上图所示,节点B属于多个群组,不同群组下的同一个节点,对应的数据库实例是分开的,为了区分不同群组下的同一个节点,将A,B,C三个节点,分别用Group1_A(Group1下的A节点,下同),Group1_B,Group2_B,Group2_C表示。
下面以上图为例,描述搭建配置过程。
节点搭建
使用分布式存储之前,需要完成联盟链的搭建和多群组的配置,具体参考如下步骤。
准备依赖
mkdir -p ~/fisco && cd ~/fisco
# 获取build_chain.sh脚本
curl -LO https://github.com/FISCO-BCOS/FISCO-BCOS/releases/download/v2.4.1/build_chain.sh && chmod u+x build_chain.sh
生成配置文件
# 生成区块链配置文件ipconf
cat > ipconf << EOF
127.0.0.1:1 agencyA 1
127.0.0.1:1 agencyB 1,2
127.0.0.1:1 agencyC 2

# 查看配置文件
cat ipconf
127.0.0.1:1 agencyA 1
127.0.0.1:1 agencyB 1,2
127.0.0.1:1 agencyC 2
使用build_chain搭建区块链
### 搭建区块链(请先确认30300~30302,20200~20202,8545~8547端口没有被占用)
### 这里区别是在命令后面追加了参数"-s MySQL" 以及换了端口。
bash build_chain.sh -f ipconf -p 30300,20200,8545 -s MySQL

修改节点ini文件
group.[群组].ini配置文件中,和本特性相关的是MySQL的配置信息。假设MySQL的配置信息如下:
|节点|db_ip|db_port|db_username|db_passwd|db_name|
|Group1_A|127.0.0.1|3306|root|123456|db_Group1_A|

启动节点
cd ~/fisco/nodes/127.0.0.1;sh start_all.sh
检查进程

启动成功,3个fisco-bcos进程。不成功的话请参考日志确认配置是否正确。
检查日志输出
执行下面指令,查看节点node0链接的节点数(其他节点类似)
tail -f nodes/127.0.0.1/node0/log/log* | grep connected
正常情况会看到类似下面的输出,从输出可以看出node0与另外2个节点有连接。

通过代理访问MySQL
本使用手册仅对节点版本2.1.0以及以后的版本有效,需要在2.0.0-rc3或者2.0.0中使用“通过代理访问MySQL”的访问方式去搭建分布式存储环境。请参考文档分布式存储搭建方法。需要在2.0.0-rc2中使用“通过代理访问MySQL”的访问方式去搭建分布式存储环境。请参考文档分布式存储搭建方法
重要
推荐使用MySQL模式。
逻辑架构图
多群组架构是指区块链节点支持启动多个群组,群组间交易处理、数据存储、区块共识相互隔离的。因此群组下的每一个节点对应一个amdb-proxy实例,例如,区块链网络中,有三个节点A,B,C,其中A,B属于群组1,B,C属于群组2。节点A和C分别对应1个数据库实例,B节点对应了2个数据库实例,逻辑架构图如下:
如上图所示,节点B属于多个群组,不同群组下的同一个节点,对应的amdb-proxy服务和MySQL是分开的,为了区分不同群组下的同一个节点,将A,B,C三个节点,分别用Group1_A(Group1下的A节点,下同),Group1_B,Group2_B,Group2_C表示。 下面以上图为例,描述搭建配置过程。
节点搭建
配置amdb-proxy服务之前,需要完成联盟链的搭建和多群组的配置,具体参考如下步骤。

源码获取
cd ~/fisco;
git clone https://github.com/FISCO-BCOS/amdb-proxy.git

配置amdb-proxy
amdb-proxy与节点连接过程,amdb-proxy是client,节点是server,启动过程是amdb-proxy服务主动连接节点,节点只需要配置amdb-proxy关注的topic即可,关于topic的介绍请参考AMOP,amdb-proxy需要通过证书准入。
证书配置
cp ~/fisco/nodes/127.0.0.1/sdk/* ~/fisco/AMDB/dist/conf/
amdb实例拷贝
cd ~/fisco;
###dist_Group1_A是节点Group1_A对应的amdb实例
cp AMDB/dist/ dist_Group1_A -R
###dist_Group1_B是节点Group1_B对应的amdb实例
cp AMDB/dist/ dist_Group1_B -R
###dist_Group2_B是节点Group2_B对应的amdb实例
cp AMDB/dist/ dist_Group2_B -R
###dist_Group2_C是节点Group2_C对应的amdb实例
cp AMDB/dist/ dist_Group2_C -R
经过上述步骤,可以看到~/fisco目录的文件结构如下:
drwxrwxr-x 8 fisco fisco 4096 May 7 15:53 AMDB

CREATE DATABASE `bcos_Group1_A`;
CREATE DATABASE `bcos_Group1_B`;
CREATE DATABASE `bcos_Group2_B`;
CREATE DATABASE `bcos_Group2_C`;
配置文件配置
这里假设MySQL的配置信息如下:
|节点|db_ip|db_port|db_username|db_passwd|db_name|
|Group1_A|127.0.0.1|3306|root|123456|bcos_Group1_A|
|Group1_B|127.0.0.1|3306|root|123456|bcos_Group1_B|
|Group2_B|127.0.0.1|3306|root|123456|bcos_Group2_B|
|Group2_C|127.0.0.1|3306|root|123456|bcos_Group2_C|
配置过程需要修改applicationContext.xml文件,需要修改的配置项包括topic配置node.topic,MySQL配置信息配置包括db.ip、db.port、db.database、db.user和db.password。

启动成功,会看到有4个java进程,3个fisco-bcos进程。不成功的话请参考日志确认配置是否正确。
检查日志输出
执行下面指令,查看节点node0链接的节点数(其他节点类似)
tail -f nodes/127.0.0.1/node0/log/log* | grep connected
正常情况会看到类似下面的输出,从输出可以看出node0与另外2个节点有连接。
info|2019-05-07 21:47:22.849910| [P2P][Service] heartBeat connected count,size=2
info|2019-05-07 21:47:32.849970| [P2P][Service] heartBeat connected count,size=2
info|2019-05-07 21:47:42.850024| [P2P][Service] heartBeat connected count,size=2
执行下面指令,检查是否在共识
tail -f nodes/127.0.0.1/node0/log/log* | grep +++
正常情况会不停输出++++Generating seal表示共识正常。
