前言
本文档旨在描述在 BigCloud Enterprise Linux (BCLinux) 8.4 操作系统环境下部署 磐维数据库（PanWeiDB） 的相关配置和背景信息。以及遇到的坑点，通过这篇文章，能让我们小伙伴们，以此版本操作系统部署磐维数据库时，能避免坑点，快速部署，以下为环境和软件的具体信息：

基础环境准备
硬件准备
为8C16G内存.
操作系统版本
BigCloud Enterprise Linux release 8.4 (Core)
4.19.0-348.20.23.el8.bclinux.x86_64
Cpu型号
processor : 3
vendor_id : GenuineIntel
cpu family : 6
model : 85
model name : Intel Xeon Processor
根据操作系统和CPU选数据库版本
PanWeiDB_V2.0-S3.0.2_B02-install-bclinux_8.2-x86_64-no_mot.tar.gz
基础环境组件
整体上检查和配置服务器的基础环境，包括安全性（防火墙和 SSH 配置）、时间同步（时区设置）、软件依赖（Python 版本）以及网络性能（MTU 设置，可选）。这些步骤在部署数据库或其他服务之前非常重要，能够确保系统具备正确的配置和依赖项，同时为后续的操作提供一个稳定、高效的运行环境。
systemctl status firewall #防火墙
ll /etc/localtime #时间
python3 --version -> 3.6.8 #可以用
cat /etc/hostname #主机名
/etc/ssh/sshd config -> PermitRootLogin yes #安装时需要root 帐户远程登录访问权限
ifconfig eth0 mtu 8192 # （可选）
必要软件包安装
BigCloud Enterprise Linux 8.4上检查并安装一系列必要软件包的过程。通过rpm -qa | grep 软件包名命令来查询特定软件包是否已经安装，其中涵盖了bzip2、expect、libaio-devel、flex、bison、ncurses-devel、glibc-devel以及gcc和gcc-c++编译器等关键工具和库文件。对于未检测到的软件包，比如libaio-devel、bison、ncurses-devel等，则建议使用yum install 软件包名 -y命令进行自动安装。特别注意和磐维官方数据库说明不一样的是：不需要对redhat-lsb-core的安装，也没有查询到该软件包。
rpm -qa |grep redhat-lsb-core #此项若没有查询到，不需要安装。
[root@ecs-79499467 ~]# rpm -qa |grep bzip2
bzip2-libs-1.0.6-26.el8.x86_64

关闭THP
Transparent Huge Pages (THP) 是 Linux 内核的一项功能，旨在通过使用更大的内存页（通常是 2MB 或更大）来优化内存管理，从而提高性能，在某些特定场景下（尤其是数据库和其他对内存敏感的应用程序），启用 THP 可能会导致性能问题甚至系统不稳定，许多数据库和高性能应用在生产环境中会禁用 THP。
cat >> /etc/systemd/system/disable-thp.service << EOF
[Unit]
Description=Disable Transparent Huge Pages (THP)
[Service]
Type=simple
ExecStart=/bin/sh -c "echo 'never' > /sys/kernel/mm/transparent hugepage/enabled && echo 'never' > /sys/kernel/mm/transparent hugepage/defrag"
[Install]
WantedBy=multi-user.target
EOF
#重启
systemctl daemon-reload
systemctl start disable-thp.service
systemctl enable disable-thp.service
#检查
cat /sys/kernel/mm/transparent hugepage/enabled
添加RemoveIPC=no
RemoveIPC=no 是一个常见的配置选项，用于防止系统在用户注销时自动删除其相关的 IPC（Inter-Process Communication，进程间通信）资源（如共享内存、信号量等）。这对于某些需要持久化 IPC 资源的应用程序（如数据库或其他后台服务）非常重要。
vim /usr/lib/systemd/system/systemd-logind.service 添加到末尾
