#分布式部署

本文以典型规格（3台服务器，1个MN组、2个CN、1个DN组，DN组和MN组均为1主2备）为例，介绍分布式部署形态的安装步骤。

执行安装部署前，请以安装用户（yashan）登录192.168.1.2服务器，并进入/home/yashan/install安装目录。

$ cd /home/yashan/install

# DN节点1主1备部署

以使用三台服务器部署1个MN组（MN节点1主2备）、2个CN、1个DN组（DN节点1主1备）的规格为例，介绍分布式部署形态的安装步骤。

# 步骤1: 生成部署文件

执行yasboot package命令生成配置文件，命令详细参数可查阅yasboot。

$ ./bin/yasboot package de gen --cluster yashandb -u yashan -p password --ip 192.168.1.2,192.168.1.3,192.168.1.4 --port 22 --install-path /data/yashan/yasdb_home --data-path /data/yashan/yasdb_data --begin-port 1688 --mn 3 --cn 2 --dn 1-2

参数	说明
--cluster	指定数据库集群名称，该名称也将作为初始数据库的名称（database name）
--port	指定SSH服务端口
--install-path	指定数据库安装路径
--data-path	指定数据存放目录
--begin-port	指定第一个CN节点上数据库监听端口
--mn/cn/dn	分别指定MN节点/CN节点/DN组-节点数量

用于提高数据库性能的参数：

参数	说明
--create-cgroup	可选参数，指定创建cgroup目录仅需开启CPU等资源管理时需配置该参数，具体请查阅配置资源管理
--recommend-param	可选参数，开启并使用推荐的配置参数
--memory-limit	可选参数，服务器的可使用内存百分比上限，须配合--recommend-param使用
----table-type	可选参数，主要的业务的表类型，该参数会使数据库配置参数更适合此表类型，须配合--recommend-param使用

执行完毕后，当前目录下将生成yashandb.toml和hosts.toml两个配置文件，可手动修改，但不建议删除文件中任何行，否则可能导致后续安装过程报错，或所搭建的环境后续无法进行扩展配置。

yashandb.toml：数据库集群的配置文件。
hosts.toml：服务器的配置文件。

-rw-------. 1 yashan yashan       444 Aug 31 16:27 hosts.toml
-rw-------. 1 yashan yashan       708 Aug 31 16:27 yashandb.toml

根据实际需要调整yashandb.toml配置文件中的安装参数，可在group级别设置YashanDB的所有建库参数，在node级别设置YashanDB的所有配置参数。

# 步骤2: 执行安装

场景一：直接安装。

$ ./bin/yasboot package install -t hosts.toml -i yashandb-23.2.0.2-linux-x86_64.tar.gz

场景二：如需使用DBLINK功能和更丰富的内置函数（例如LSFA_LISTAGG），需先下载plugin插件包并在安装命令中指定--plugin参数。安装完成后，无法单独安装该插件包。

$ ./bin/yasboot package install -t hosts.toml -i yashandb-23.2.0.2-linux-x86_64.tar.gz --plugin yashandb-plugins-all-23.2.0.2-linux-x86_64.tar.gz

# 步骤3: 数据库部署

$ ./bin/yasboot cluster deploy -t yashandb.toml

Note:

可通过指定-d, --child参数展示任务以及子任务信息，从而了解部署进度。

返回如下信息表示已成功部署。

task completed, status: SUCCESS

# 步骤4：配置环境变量

以安装用户登录到每个服务器上，执行如下命令生效环境变量。

# 部署命令成功执行后将会在$YASDB_HOME目录下的conf文件夹中生成<<集群名称>>.bashrc环境变量文件
$ cd /data/yashan/yasdb_home/yashandb/23.2.0.2/conf
# 如~/.bashrc中已存在YashanDB相关的环境变量，将其清除

$ cat yashandb.bashrc >> ~/.bashrc
$ source ~/.bashrc

# 步骤5：检查安装结果

若连接报错或执行SQL语句报错，请根据错误提示信息检查安装步骤，或咨询我们的技术支持。

YashanDB不提供系统初始口令，需使用yasboot工具设置数据库sys用户的密码，以安装用户登录到服务器并执行如下命令设置密码。

$ yasboot cluster password set -n newpasswd -c yashandb

执行如下命令，查看数据库状态。

$ yasboot cluster status -c yashandb -d

# 步骤6（可选）：开启仲裁选主

如需实现DN组内节点的主备自动切换，需开启基于yasom的仲裁选主。

Note:

如需开启monit功能，可参考守护进程完成相关配置。
