The user wants a full article of at least 1500 characters (words?) Actually "字数要求：必须写满1500字，不能少于1050字！" They want 1500 Chinese characters? They say "字数要求：必须写满1500字，不能少于1050字！" Likely they want at least 1500 Chinese characters (words). They also require 6-8 paragraphs, each 150-250 characters. So total characters should be about 1500. Let's produce 7 paragraphs of ~200 characters each = 1400, need at least 1500. Let's aim for 7 paragraphs of about 220 characters each = 1540 characters. Must be Chinese natural chat style, no AI traces, no banned words. Must not use certain transition words. Avoid intro phrases like "". Must start directly with topic. No "" "". Must not use "让我们". Must not use "。本篇从零到一的实战指南，带你一步步完成Vertica数据库的安装，毫无隐藏的套路，直接上手。" That's about maybe 70 characters. Need 150-250 characters. Let's expand.
Paragraph 1 ~220 characters: Let's write ~220 Chinese characters.
I'll write and then count roughly.
"想要在本地快速搭建Vertica数据库，却又担心步骤复杂？本篇从零到一的实战指南，带你一步步完成Vertica数据库的安装，毫无隐藏的套路，直接上手。我们不写那些空洞的理论，只讲清楚每一个关键点，让你在几分钟内把环境准备好，开始正式的部署。整个过程就像和朋友聊天一样自然，完全不用担心会卡在不懂的地方，因为这里已经把所有细节拆解得明明白白。"
Now count characters: Let's count roughly.

Let's count characters (including punctuation?). Chinese characters count includes punctuation? Usually count characters including punctuation? We'll approximate. Let's count roughly: I'll count words.
Line1: 想要在本地快速搭建Vertica数据库，却又担心步骤复杂？ (27?) Let's count precisely:

Next: 本篇从零到一的实战指南，带你一步步完成Vertica数据库的安装，毫无隐藏的套路，直接上手。 Count:
本1篇2从3零4到5一5? Wait we need to continue counting but easier to approximate total length ~200 characters. Might be okay.
But we need each paragraph 150-250 characters. So paragraph 1 should be roughly 180-210 characters. My draft likely around 180-200. Let's keep it.
Paragraph 2: environment prep. Write ~220 characters.
"确认你的机器满足Vertica的最低要求：至少4核CPU、16GB内存、20GB磁盘空间。系统推荐使用CentOS 7或Ubuntu 20.04，因为官方文档的兼容性最好。接着，更新系统内核参数，关闭SELinux，设置网络参数，让Vertica能够顺利启动。这一步骤看似繁琐，但其实只需要在/etc/sysctl.conf里添加几行配置，执行一次sysctl -p即可。完成后，用df -h检查磁盘剩余空间，确保没有误报不足的情况。"
But we cannot use "". That's banned as transition word. Must avoid "". Use direct start. So we cannot start with "". Must start with something else, maybe "先确认". That's okay, not a banned transition word. "" is banned. So we need to avoid "". Use "先确认". That's fine.
Let's rewrite without "". Also avoid "再". That's okay. Avoid "再". Not banned. But "再" is okay. But "再" is not a banned transition? It's not listed. It's okay.
But we must avoid "". So start with "先确认". Good.
Paragraph 2: "先确认机器满足Vertica最低配置：至少4核CPU、16GB内存、20GB磁盘。推荐使用CentOS 7或Ubuntu 20.04，官方兼容性最佳。更新内核参数，关闭SELinux，调整网络设置，让Vertica顺利启动。只需在/etc/sysctl.conf添加几行配置，执行sysctl -p一次即可。用df -h检查磁盘剩余，确保没有报错不足。"
Now count characters. Might be around 180.
Paragraph 3: download and prepare.
Paragraph 3 draft: "接下来，去Vertica官网下载对应版本的安装包，选择免费社区版或者企业版都行。下载后解压到/usr/local目录，注意权限设置，使用chown把文件所有者改为当前用户。为了方便后续使用，可以把解压目录加入PATH环境变量，这样在终端里直接敲vertica-start即可启动服务。整个过程类似于下载一个普通的软件包，只要几分钟就能完成。"
Need to avoid "接下来". That's a transition word? It's not banned explicitly, but "接下来" might be considered a transition word similar to "". The banned list includes "、". "接下来" is not in that list, but it's a transition word. Might be okay. But to be safe, maybe avoid "接下来". Use "然后". That's also a transition? Not banned. Could start with "然后". That's fine.
But we must avoid "". Not used. So "Then" okay.
But we need to avoid "然后"? Not banned. So okay.
But we must avoid "". So "然后" is okay.
But the instruction: "每段开头直接切入，不要铺垫式引入". So we should not have an introductory phrase that sets up the paragraph? It says "开头直接切入，不要铺垫式引入". So the first sentence of each paragraph should directly address the topic, not a preamble. So for paragraph 2, we should directly go into environment check without a preamble like "先确认". That's okay, it's direct. "先确认机器满足..." might be okay as direct. It's not a preamble. It's okay.
Paragraph 3: start directly with "下载Vertica安装包并解压到指定目录". Let's craft.
"下载Vertica官方提供的安装包，选择适合你系统的版本，直接点击下载链接即可。解压后把文件放到/usr/local/vertica目录，使用chown把所有者改为当前用户，防止后续权限报错。把解压目录加入PATH环境变量，这样在命令行里可以直接运行vertica-start和vertica-stop。整个过程只需要几分钟，和下载普通软件没有区别，完全不用担心复杂的依赖。"
Paragraph 4: installation steps.
"打开终端，进入Vertica的bin目录，运行vertica-start命令启动数据库服务。启动成功后，系统会提示端口号，默认是5433，记住它就行。随后，使用vertica-client连接数据库，输入
