网站架构：LNMP（Linux、Nginx、MySQL、PHP）

一、环境准备

1. 操作系统：CentOS 7.x（推荐使用稳定版，例如CentOS 7.9）
2. 软件版本：
   • MySQL：5.7.35（稳定版）
   • PHP：7.4.33（支持WordPress的最新稳定版）
   • Nginx：1.20.2（稳定版）
   • WordPress：最新版本（例如5.8.1，具体版本以下载为准）

二、安装MySQL 5.7.35

1. 安装依赖包：bash复制yum install -y libaio numactl-libs
2. 下载MySQL二进制文件：bash复制wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.35-linux-glibc2.12-x86_64.tar.gz
3. 解压并安装MySQL：bash复制tar -xzf mysql-5.7.35-linux-glibc2.12-x86_64.tar.gz -C /usr/local/ ln -s /usr/local/mysql-5.7.35-linux-glibc2.12-x86_64 /usr/local/mysql
4. 创建MySQL用户和数据目录：bash复制groupadd -r mysql useradd -r -g mysql -s /sbin/nologin -d /data/mysql mysql mkdir -p /data/mysql chown -R mysql:mysql /data/mysql
5. 初始化MySQL：bash复制/usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql
6. 配置MySQL：
   • 创建my.cnf配置文件：ini复制[mysqld] basedir = /usr/local/mysql datadir = /data/mysql socket = /data/mysql/mysql.sock log-error = /data/mysql/mysql_error.log pid-file = /data/mysql/mysql.pid [client] socket = /data/mysql/mysql.sock
   • 将my.cnf放置到/etc/my.cnf：bash复制cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf
7. 启动MySQL服务：bash复制cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld chmod +x /etc/init.d/mysqld systemctl enable mysqld systemctl start mysqld
8. 获取临时密码并设置MySQL密码：bash复制temp_password=$(grep 'temporary password' /data/mysql/mysql_error.log | awk '{print $NF}') /usr/local/mysql/bin/mysqladmin -uroot -p"$temp_password" password 'your_new_password'

三、安装PHP 7.4.33

1. 安装依赖包：bash复制yum install -y libxml2-devel openssl-devel bzip2-devel libcurl-devel
2. 下载并编译安装PHP：bash复制wget https://www.php.net/distributions/php-7.4.33.tar.gz tar -xzf php-7.4.33.tar.gz cd php-7.4.33 ./configure --prefix=/usr/local/php \ --with-config-file-path=/usr/local/php/etc \ --enable-fpm \ --with-mysqli=mysqlnd \ --with-pdo-mysql=mysqlnd \ --with-openssl \ --with-zlib \ --enable-mbstring \ --enable-xml \ --enable-json make && make install
3. 配置PHP：
   • 复制php.ini配置文件：bash复制cp php.ini-production /usr/local/php/etc/php.ini
   • 配置php-fpm：bash复制cp sapi/fpm/php-fpm.service /etc/systemd/system/php-fpm.service systemctl enable php-fpm systemctl start php-fpm

---

四、安装Nginx 1.20.2

1. 安装依赖包：bash复制yum install -y pcre-devel zlib-devel
2. 下载并编译安装Nginx：bash复制wget http://nginx.org/download/nginx-1.20.2.tar.gz tar -xzf nginx-1.20.2.tar.gz cd nginx-1.20.2 ./configure --prefix=/usr/local/nginx make && make install
3. 配置Nginx：
   • 修改nginx.conf配置文件：nginx复制server { listen 80; server_name your_domain.com; root /var/www/html; index index.php index.html; location / { try_files $uri $uri/ =404; } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } }
   • 启动Nginx：bash复制/usr/local/nginx/sbin/nginx

五、安装WordPress

1. 下载WordPress：bash复制wget https://wordpress.org/latest.tar.gz tar -xzf latest.tar.gz -C /var/www/html chown -R nginx:nginx /var/www/html/wordpress
2. 配置WordPress：
   • 创建wp-config.php文件：php复制define('DB_NAME', 'wordpress'); define('DB_USER', 'wordpress'); define('DB_PASSWORD', 'your_password'); define('DB_HOST', 'localhost'); define('DB_CHARSET', 'utf8'); define('DB_COLLATE', '');
   • 创建MySQL数据库和用户：sql复制CREATE DATABASE wordpress DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci; CREATE USER 'wordpress'@'localhost' IDENTIFIED BY 'your_password'; GRANT ALL PRIVILEGES ON wordpress.* TO 'wordpress'@'localhost'; FLUSH PRIVILEGES;
3. 访问网站：
   • 打开浏览器，访问http://your_domain.com/wordpress，按照WordPress安装向导完成配置。
