We need to write an article of 1500+ characters (words? The user says "字数要求：必须写满1500字，不能少于1050字！" They likely mean Chinese characters count, not words. They want an article, no title, direct output of the body. Must be 6-8 paragraphs, each 150-250 Chinese characters (or words?). It says each paragraph 150-250 words? It says "每段150-250字" which means characters. So each paragraph must be 150-250 Chinese characters. With 6-8 paragraphs, total characters must be at least 1500 characters (since each paragraph at least 150 characters, 6150=900, but they require at least 1050 characters; they also require 1500 characters minimum). Actually they require "必须写满1500字，不能少于1050字！" So total characters must be at least 1500 characters, but also cannot be less than 1050 characters. So we need to produce at least 1500 Chinese characters in total. And each paragraph 150-250 characters. So we can do 8 paragraphs of about 190 characters each (8190=1520). That meets both requirements.
We must not output title, only the article body. Need to be natural, conversational, like talking to a friend, no AI style. Must avoid certain words (they gave a list of forbidden words, but those are English? They gave "开头禁用：、; 过渡禁用：、; 结尾禁用：让我们...、。那时候想到的第一件事就是装个数据库，用来存用户信息和日志。折腾了半天，才发现官方文档里对不同发行版的指引有点碎，结果就想把整个过程系统化下来，帮别的爱折腾的朋友少走点弯路。于是今天就聊聊在 Linux 系统上装 MariaDB 的具体步骤，顺便分享几个实战小技巧。"
Now count characters: Let's count quickly. I'll count manually approximate. Better to count precisely later. But we need 150-250 characters. This paragraph seems maybe around 150? Let's count:
"去年我自己在家里组了个小服务器，想把几个常用的开源应用跑起来。" That's about 28 characters? Let's count precisely: 去(1)年2我3自4己5在6家7里8组9了10个11小12服13务14器15，16想17把18几19个20常20? Actually let's not overthink. We'll aim for ~190 characters each.
I'll produce eight paragraphs each about 190 characters. Need to ensure total >=1500 characters. 8*190=1520. Good.
Now write each paragraph without using forbidden words. Avoid "", "". Also avoid "让我们". Avoid "。那时候想到的第一件事就是装个数据库，用来存用户信息和日志。折腾了半天，才发现官方文档里对不同发行版的指引有点碎，结果就想把整个过程系统化下来，帮别的爱折腾的朋友少走点弯路。于是今天就聊聊在 Linux 系统上装 MariaDB 的具体步骤，顺便分享几个实战小技巧。" Let's count characters. I'll count roughly:
去(1)年2我3自4己5在6家7里8组9了10个11小12服13务14器15，16想17把18几19个20常21用22的23开24源25应26用27跑28起来29。30那31时32想33到34的35第36一37件38事39就40是41装42个43数44据45库46，47用48来49存50用51户52信53息54和55日56志57。58折59腾60了61半62天63，64才65发66现67官68方69文70档71里72对73不74同75发76行77版78的79指80引81有82点83碎84，85结果86就87想88把89整90个91过92程93系94统95化96下97来98，99帮100别101的102爱103折104腾105的106朋107友108少109走110点111弯112路113。114这115就116是117今118天119就120聊121聊122在123Linux124系125统126上127装128Maria129DB130的131具132体133步134骤135，136顺137便138分139享140几141个142实143战144小145技146巧147。
That's about 147 characters? Actually we counted up to 147 maybe. Need 150-250 characters. So we need a bit longer. Add some more details. Let's add "我打算把步骤拆成几段，从准备到验证，都写得清楚些。" That's about 20 characters. Let's append.
Add: "我打算把步骤拆成几段，从准备到验证，都写得清楚些。" Count characters: 我1 打2 算3 把4 步5 程6 拆7 成8 几9 段10 ，11 从12 准13 备14 到15 验16 证17 ，18 都19 写20 得21 清22 明23 查24 些25 。 That's 25 characters. So total becomes ~172 characters. Good.
So paragraph 1 will be about 172 characters, within 150-250.
Paragraph 2: talk about preparation: check OS version, update repo, maybe install required packages. Let's write ~190 characters.
"在动手之前，先确认一下自己的 Linux 发行版到底是 Ubuntu、Debian 还是 CentOS。每个发行版的包管理器不太一样，Ubuntu 用 apt，CentOS 用 yum 或 dnf。最好先跑一次系统更新，确保软件源里最新的 MariaDB 包可以直接下载。这里我通常会把系统的版本号记下来，避免以后升级冲突。"
Count characters roughly: Let's count quickly.
在1 动2 手3 之前4 ，5 先6 确7 认8 一9 下10 我? Actually "在动手之前，先确认一下自己的 Linux 发行版到底是 Ubuntu、Debian 还是 CentOS。" That's a lot. Let's approximate length ~200 characters. Should be okay.
We need to avoid using "". Not using. Also avoid "". Not using. Should be fine
