我行在 2018 年开始了基于 ARM 服务器平台的尝试，当前 TDSQL 的冷备数据全部保存在基于 ARM 服务器搭建的 CEPH 存储集群上，运行稳定。在今年贸易战的大背景下，我们数据库团队也尝试将各个数据库产品放到 ARM 平台上去编译并运行起来，为我行在基础架构层面的进一步国产化打下基础。

我们这次首先针对我行引入的 NewSQL 数据库 TiDB，在我行实验室的 ARM 平台上进行了编译和测试，预计会将整个测试流程和相关测试结论，整理为三篇技术文章分享出来，分别是:

（一）《TiDB 集群 在 arm 平台编译、安装与部署》

（二）《sysbench 测试下 arm 平台 cpu ／内存／磁盘的能力》

（三）《 TiDB 在 arm 与 x86 平台的性能测试对比》

此次是系列文章的第一篇。

一、环境准备

PingCAP 提供了 TiDB-Ansible 部署方案，可以使用 Ansible 快速方便地部署一个完整的 TiDB 集群，而 TiDB-Ansible release-3.0 版本依赖 Ansible 2.4.2 及以上版本（Ansible>=2.4.2，最好是 2.7.11 版本），另外依赖 Python 模块：jinja2 >= 2.9.6 和 jmespath >= 0.9.0，而且内部的数据库服务器与外网一般是隔离的，所以只能选择离线安装：

1、机器准备

可以连接外网的 ARM 服务器一台

• 该机器需开放外网访问

• 用于下载 TiDB-Ansible、TiDB 及相关软件安装包

• 用于编译 TiDB ARM 版本

部署目标机器三台、部署中控机一台

• 无法访问外网

• 部署目标机器为 ARM 服务器

• 部署中控机和部署目标机器共用

2、依赖包下载

以下是主要的依赖安装包（如果在安装过程中发现还缺少其他依赖包，可以按需下载）。

安装包	功能	下载方式
Ansible	PingCAP 提供了 TiDB-Ansible 部署方案，可以使用 Ansible 快速方便地部署一个完整的 TiDB 集群	在能联网的 ARM64 服务器使用 sudo yum install--downloadonly --downloaddir=./ansible ansible 命令来得到安装 ansible 的依赖 rpm 包
python2-jinja2-2.10-2.el7.noarch.rpm	python 依赖包	网络下载
python2-babel-2.7.0-1.fc31.noarch.rpm	python 依赖包	网络下载
python2-markupsafe-1.0-1.fc29.aarch64.rpm	python 依赖包	网络下载
python2-jmespath-0.9.0-1.el7.noarch.rpm	python 依赖包	网络下载
python2-pip-8.1.2-8.el7.noarch.rpm	pip 安装包	网络下载
mariadb-5.5.60-1.el7_5.aarch64.rpm	安装 mysql 客户端	网络下载
epel-release-7-11.noarch.rpm	安装扩展 epel 包	网络下载
sshpass-1.06-1.el7.aarch64.rpm	中控机 SSH 组件	网络下载

另外上图所示的依赖包只保证当前 ARM 环境可正常，但因为不同的服务器依赖可能不完全一样，所以在安装过程发现还缺少其他依赖包，若想安装其他依赖包，可自行网上寻找相关 RPM 包按需下载，实际我安装上述 RPM 包时也存在依赖性问题，但使用 RPM 强制安装已成功安装。

3、安装依赖包

二、编译 TiDB arm 版本

TiDB 包括三大组件 PD、TiKV Server 和 TiDB Server，还包括其他周边组件，比如 Pump、Prometheus、Alertmanager、Node_exporter、Blackbox_exporter、Pushgateway 和 Grafana，所以需要把这些组件都统一编译成 ARM 版本，而且要和官方版本对齐。

在 TiDB-Ansible 的 bootstrap.yml 阶段需要使用 fio 进行性能压测，所以需要额外下载一个 fio(version 3.8) 文件。

三、安装 TiDB

1、下载 tidb-ansible 以及完成相关初始化

根据 PingCAP 官网的离线 TiDB-Ansible 部署方案（https://pingcap.com/docs-cn/v3.0/how-to/deploy/orchestrated/offline-ansible/），完成以下初始化工作：

• 在中控机上创建 tidb 用户，并生成 ssh key

• 在下载机上下载 TiDB-Ansible 及 TiDB 安装包，但下载机不需要安装 ansible，具体操作如下：

下载 release-3.0 版本：

$ git clone -b v3.0.0 https://github.com/pingcap/tidb-ansible.git

注：不需要执行 ansible-playbook local_prepare.yml，因为使用的是自己编译的 ARM 版二进制包

• 在中控机上配置部署机器 ssh 互信及 sudo 规则

• 在部署目标机器上安装 NTP 服务

• 在部署目标机器上配置 CPUfreq 调节器模式

• 在部署目标机器上添加数据盘 ext4 文件系统挂载参数

2、部署任务

• 把在下载机下载好的 tidb-ansible 传到部署中控机

• 在 tidb-ansible 目录下创建 resources/bin/ 目录，并且把编译的 ARM 版二进制文件全部放到 resources/bin/ 目录里（还包括 fio 文件）

• 编辑 inventory.ini

• 启动 TiDB 集群

ansible-playbook start.yml

四、验证并使用

五、计划

至此，在 ARM64 平台上迈出坚实的一步，完成分布式数据库 TiDB 集群的安装部署，建议各位按照上面步骤进行操作，否则可能遇到一些未知的坑或者异常；接下来，我们将继续探索 ARM64 与 X86 平台差异化对比测试，通过基准硬件和分布式数据库性能两个维度深入挖掘，欢迎有兴趣的朋友一块探讨。
