PolarDB-X 简介
PolarDB-X 是一款面向超高并发、海量存储、复杂查询场景设计的云原生分布式数据库系统。其采用 Shared-nothing 与存储计算分离架构，支持水平扩展、分布式事务、混合负载等能力，具备企业级、云原生、高可用、高度兼容 MySQL 系统及生态等特点。
PolarDB-X 最初为解决阿里巴巴天猫“双十一”核心交易系统数据库扩展性瓶颈而生，之后伴随阿里云一路成长，是一款经过多种核心业务场景验证的、成熟稳定的数据库系统。 PolarDB-X 的核心特性如下：
水平扩展
PolarDB-X 采用 Shared-nothing 架构进行设计，支持多种 Hash 和 Range 数据拆分算法，通过隐式主键拆分和数据分片动态调度，实现系统的透明水平扩展。
分布式事务
PolarDB-X 采用 MVCC + TSO 方案及 2PC 协议实现分布式事务。事务满足 ACID 特性，支持 RC/RR 隔离级别，并通过一阶段提交、只读事务、异步提交等优化实现事务的高性能。
混合负载
PolarDB-X 通过原生 MPP 能力实现对分析型查询的支持，通过 CPU quota 约束、内存池化、存储资源分离等实现了 OLTP 与 OLAP 流量的强隔离。
企业级
PolarDB-X 为企业场景设计了诸多内核能力，例如 SQL 限流、SQL Advisor、TDE、三权分立、Flashback Query 等。
云原生
PolarDB-X 在阿里云上有多年的云原生实践，支持通过 K8S Operator 管理集群资源，支持公有云、混合云、专有云等多种形态进行部署，并支持国产化操作系统和芯片。
高可用
通过多数派 Paxos 协议实现数据强一致，支持两地三中心、三地五副本等多种容灾方式，同时通过 Table Group、Geo-locality 等提高系统可用性。
兼容 MySQL 系统及生态
PolarDB-X 的目标是完全兼容 MySQL ，目前兼容的内容包括 MySQL 协议、MySQL 大部分语法、Collation、事务隔离级别、Binlog 等。
编译平台
PRETTY_NAME=“Ubuntu 22.04.4 LTS”
NAME=“Ubuntu”
VERSION_ID=“22.04”
VERSION=“22.04.4 LTS (Jammy Jellyfish)”
VERSION_CODENAME=jammy
ID=ubuntu
ID_LIKE=debian
源码编译
编译存在两种方式
第一种 直接使用现成的项目脚本 完成一键编译 一键部署 一键停止
git clone https://github.com/polardb/polardbx
cd polardbx
make
# 启动
./build/run/bin/polardb-x.sh start
# 停止
./build/run/bin/polardb-x.sh stop
另一种 如下文 称之为hard模式 参考本文 即可规避绝大多数问题
编译 DN 存储节点（代号polardbx-engine）
安装依赖
centos 未实测
yum install cmake3
ln -s /usr/bin/cmake3 /usr/bin/cmake
# 安装GCC7
yum install centos-release-scl
yum install devtoolset-7-gcc devtoolset-7-gcc-c++ devtoolset-7-binutils
echo "source /opt/rh/devtoolset-7/enable" >>/etc/profile
# 安装依赖
yum install make automake git openssl-devel ncurses-devel bison libaio-devel
ubuntu 操作
鉴于不同版本的不一致 故在此特此说明 当前ubuntu的版本 22.04 完整的版本信息 可参加 编译平台 章节
# 安装GCC7
# 官方文档中 使用 gcc-7 g++-7 但是尝试后 会报错 故修改为如下
apt install -y gcc g++
update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 60 \
--slave /usr/bin/g++ g++ /usr/bin/g++-7
update-alternatives --config gcc
gcc --version
g++ --version
# 安装依赖
apt install make automake cmake git bison libaio-dev libncurses-dev libsasl2-dev libldap2-dev libssl-dev pkg-config
# 补充依赖包
sudo apt install libsnappy-dev zlib1g-dev libbz2-dev liblz4-dev
特此说明: 在linux环境下 检查文件夹的所属目录权限以及用户组 是否和登录的用户匹配 ，不然可能导致文件读取不到 或者无法写入
下载源码
# git clone 或者 直接下载zip压缩包
git clone https://github.com/polardb/polardbx-engine.git
编译
# 保持网络畅通
make -j8
make install
接着就是等待编译完成
编译完成
会在编译的根目录的上级目录 或者本机目录生成一个 t-polardbx-engine-2.4.0
目录内结构如下：
进入到opt里 即可看到 polardbx-engine 文件夹 里面存放就是编译后的内容
后续我们就基于此文件进行部署。
编译 CN 计算节点（代号polardbx-sql）
环境准备
maven 3.5 +
jdk 11 +
源码下载
# 最好使用这种方式 进行下载源码 不要直接下载zip包
git clone https://github.com/polardb/polardbx-sql.git
# 进入代码目录
cd polardbx-sql/
# 确保 polardbx-rpc 子模块 (polardbx-glue) 已初始化
git submodule update --init
编译
# 编译打包
mvn install -D maven.test.skip=true -D env=release
编译完成
编译完成后 在target目录下 即可看到压缩包
这个就是后续要安装的压缩包
编译 CDC 计算节点（代号polardbx-cdc）
环境准备
maven 3.5 +
jdk 11 +
源码下载
# 最好使用这种方式 进行下载源码 或者直接下载zip包
git https://github.com/polardb/polardbx-cdc.git
编译
# 编译打包
mvn install -D maven.test.skip=true -D env=release
编译完成
编译完成后 在polardbx-cdc-assemble的target目录下 即可看到压缩包
这个就是后续要安装的压缩包
安装
安装过程注定不平凡，接下来开始安装
安装包准备
由于 CN 和 CDC 我是放在本机的 idea上编译的 所以后续需要统一放到一个 目录下 方便安装
如果都是在服务器上操作的 直接cp到同一个目录即可
安装 DN (代号：polardbx-engine)
- 此步骤启动一个mysql进程，作为metadb和dn
- 准备 mysql配置文件（my.cnf），可进行相应修改，默认使用 4886 作为 mysql端口，32886 作为私有协议端口
- 默认使用 /usr/local/develop/PolarDB-X/polardbx_engine 作为mysql数据目录，可以修改成其他目录
根目录新建conf目录 新建 my.cnf 内容如下
重点配置说明 强制执行 rpc_port端口为32886 不然默认是33660 导致连接不上

启动msql
注意：启动 DN 需要使用非 root 账号完成
# DN根目录
# 初始化
./bin/mysqld --defaults-file=/usr/local/develop/PolarDB-X/polardbx_engine/conf/my.cnf --initialize-insecure
# 启动 会在根目录输出一个 out.log
nohup ./bin/mysqld --defaults-file=/usr/local/develop/PolarDB-X/polardbx_engine/conf/my.cnf >./out.log 2>&1 &

## 重复之前的启动过程
安装 CN (代号：polardbx-sql)
启动mysql进程之后，便可以初始化PolarDB-X，需要准备以下几个配置：
metadb user：以下采用my_polarx
metadb database：创建metadb库，以下采用 polardbx_meta_db_polardbx
密码加密key（dnPasswordKey)：以下采用 asdf1234ghjk5678
PolarDB-X默认用户名：默认为 polarx_root
PolarDB-X默认用户密码：默认为 123456，可通过 -S 参数修改
注意：启动 CN 需要使用非 root 账号完成
删除原有配置文件 conf/server.properties，在重新新建
路径配置使用 /usr/local/develop/PolarDB-X/polardbx-binlog 前缀 如果想替换 请全部替换
重点配置说明 galaxyXProtocol=2 必须要改成2 不然导致连接不上错误

此步骤中会生成内部密码及加密密码，需要将其填写配置文件 conf/server.properties 中，用于后续访问:

Initialize polardbx success
看到 Initialize polardbx success 表明初始化成功 部署成功了一大半
另外需要将生成的 密码 metaDbPasswd=27qEwnDfG/6sB/YCId+yQMEUYZmaPJyjvBaFcrnXKEo= 更新到 conf/server.properties 注意空格
启动CN
bin/startup.sh -P asdf1234ghjk5678
观察启动日志
日志文件在根目录下的logs/tddl下 主要日志 tddl.log 和 meta-db.log 里
连接测试
# 在localhost下免密登录的 登录后即可看到 内容
mysql -h127.1 -P8527 -upolardbx_root
默认是没有数据库的 能登录进来 即可说明 DN部署成功
失败重试
# 登录 DN的数据库 删除 polardbx_meta_db_polardbx 库

# 删除 pid
# 重新启动会报错提示 pid具体的路径 直接删除即可
安装 CDC (代号：polardbx-cdc)
终于到了这里 。。。。。 继续开始
启动PolarDB-X进程之后，便可以初始化PolarDB-X CDC组件，需要准备以下几个配置：
metadb user：和启动PolarDB-X时设置的值保持一致，以下采用my_polarx
metadb database：和启动PolarDB-X时设置的值保持一致，以下采用 polardbx_meta_db_polardbx
metadb password：和启动PolarDB-X时设置的值保持一致，需使用密文，以下采用HMqvkvXZtT7XedA6t2IWY8+D7fJWIJir/mIY1Nf1b58=
metadb port：和启动MySQL时设置的值保持一致，以下采用 4886
密码加密key（dnPasswordKey)：和启动PolarDB-X时设置的值保持一致，以下采用 asdf1234ghjk5678
PolarDB-X用户名：和启动PolarDB-X时设置的值保持一致，以下采用默认值 polardbx_root
PolarDB-X用户密码：和启动PolarDB-X时设置的值保持一致，需使用密文，以下采用默认值H1AzXc2NmCs61dNjH5nMvA==
PolarDB-X端口：和启动PolarDB-X时设置的值保持一致，以下采用默认值 8527
当前机器分配给CDC使用的内存大小：以下采用16000代指，单位为M，实际配置值请替换为真实值
注意：启动 CDC 需要使用非 root 账号完成
删除config/server.properties 文件 并重新创建一个 内容如下

启动 CDC
接下来，即可启动CDC daemon进程，命令如下所示。启动之后，通过jps命令查看进程状态，CDC会有3个附属进程，分别是DaemonBootStrap、TaskBootStrap和DumperBootStrap，CDC的系统日志会输出到${HOME}/logs目录下，全局binlog日志会输出到binlog.dir.path参数配置的目录下，TaskBootStrap进程和DumperBootStrap进程被kill后，会被Daemon进程自动拉起。
当 runtime_mode=LOCAL_SINGLE 只会有一个进程DaemonBootStrap 其他两个 TaskBootStrap和DumperBootStrap 都内嵌在DaemonBootStrap里执行
bin/daemon.sh start
日志观察
日志文件在 ${HOME}/logs/polardbx-binlog/Daemon下
重点观察 default.log
测试
登录PolarDB-X，执行一些DDL或DML操作，然后执行show binary logs 和show binlog events命令，验证全局binlog的生成状态，
mysql -h127.1 -P8527 -upolardbx_root
show binary logs;
# 这个事件会有很多
show binlog events;
验证binlog 生成情况 执行DML 语句 以及 DDL 观察binlog日志的 position位点是否更新
show master status
失败重试
CDC的报错 大概率是配置的问题 如果按照如上配置 即可规避90% 以上的错误 如果还有其他的报错，结合日志文件进行具体分析。
参考文档: https://doc.polardbx.com/zh/quickstart/topics/quickstart-development.html
结尾
遇到错误的话 多看日志 结合源码分析错误问题。
在linux环境下 检查文件夹的所属目录权限以及用户组 是否和登录的用户匹配 ，不然可能导致文件读取不到 或者无法写入 。
good day ！！！
