1.获取与系统版本匹配的nginx rpm包
wget http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

2.建立nginx的yum仓库
rpm -ivh nginx-release-centos-7-0.el7.ngx.noarch.rpm

3.安装nginx
yum install -y nginx

4.启动nginx,同时设置开机自启动
systemctl start nginx
systemctl enable nginx

5.打开浏览器访问ip地址，出现welcome nginx说明安装成功

1.获取mysql rpm包
wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
wget -i -c https://mirrors.cloud.tencent.com/mysql/yum/mysql-5.7-community-el7-x86_64/mysql-community-client-5.7.10-1.el7.i686.rpm 

2.建立mysql的rpm仓库
rpm -ivh mysql57-community-release-el7-10.noarch.rpm 

3.下载mysql
yum -y install mysql-community-server --nogpgcheck

4.启动mysqld服务并且设置开机自启动
systemctl start mysqld
systemctl enable mysqld

5.查看mysqld服务运行状态
systemctl status mysqld
//有如下结果说明mysql安装成功

12月 13 10:39:11 hecs-35106 systemd[1]: Started MySQL Server.

查看mysql版本
mysql -V
mysql  Ver 14.14 Distrib 5.7.40, for Linux (x86_64) using  EditLine wrapper

6.配置mysql密码
获取mysql安装时自动配置的密码
grep 'temporary password' /var/log/mysqld.log

7.mysql加固
mysql_secure_installation

Securing the MySQL server deployment.

Enter password for user root:    #输入上一步骤中获取的安装MySQL时自动设置的root用户密码
The existing password for the user account root has expired. Please set a new password.

New password:  #设置新的root用户密码
注意：mysql5.7默认密码策略要求密码必须是 大小写字母 ，数字 ，特殊字母的组合，至少8位

Re-enter new password:   #再次输入密码
The 'validate_password' plugin is installed on the server.
The subsequent steps will run with the existing configuration of the plugin.
Using existing password for root.

Estimated strength of the password: 100
Change the password for root ? ((Press y|Y for Yes, any other key for No) : N   #是否更改root用户密码，输入N

 ... skipping.
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.

Remove anonymous users? (Press y|Y for Yes, any other key for No) : Y   #是否删除匿名用户，输入Y
Success.

Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : Y   #禁止root远程登录，输入Y
Success.

By default, MySQL comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment.

Remove test database and access to it? (Press y|Y for Yes, any other key for No) : Y   #是否删除test库和对它的访问权限，输入Y
 - Dropping test database...
Success.

 - Removing privileges on test database...
Success.

Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : Y   #是否重新加载授权表，输入Y
Success.

All done!

1.查看是否已经安装过php
php -v

2.卸载低版本php
yum remove -y php*

3.安装yum工具类库
yum install -y yum-utils

4.更换yum源
yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm 
yum install https://rpms.remirepo.net/enterprise/remi-release-7.rpm

5.为PHP 8启用流模块：
yum-config-manager --disable 'remi-php*'
yum-config-manager --enable remi-php80

6.安装php8及其扩展
yum install -y php 
//yum install -y php-{extension_name}
yum -y install php-tidy php-common php-devel php-pdo php-mysql php-gd php-ldap php-mbstring php-mcrypt php-fpm

7.查看php是否安装成功
php -v
PHP 8.0.26 (cli) (built: Nov 22 2022 17:44:09) ( NTS gcc x86_64 )
Copyright (c) The PHP Group
Zend Engine v4.0.26, Copyright (c) Zend Technologies

8.配置nginx的default.conf，取消ipv6监听，同时配置nginx，实现与php联动
server {
    listen       80;
    root   /usr/share/nginx/html;
    server_name  localhost;
    #charset koi8-r;
    #access_log  /var/log/nginx/log/host.access.log  main;
    #
    location / {
          index index.php index.html index.htm;
    }
    #error_page  404              /404.html;
    #redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
      root   /usr/share/nginx/html;
    }
    #pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    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;
    }
}

7.重启nginx服务，启动php-fpm服务，并设置开机自启动
systemctl restart nginx
systemctl start php-fpm
systemctl enable php-fpm

8.验证环境配置
echo "<?php phpinfo(); ?>" >> /usr/share/nginx/html/index.php
访问ip地址出现如下结果说明配置成功

1.创建数据库
CREATE DATABASE wordpress;

2.创建数据库用户
CREATE USER 'user'@'localhost' IDENTIFIED BY '123456';

3.对新创建的用户授予全部权限
GRANT ALL PRIVILEGES ON wordpress.* TO 'user'@'localhost';

4.刷新权限使配置生效
FLUSH PRIVILEGES;

1.删除网站根目录下用于测试php-nginx的index.php文件
rm -rf /usr/share/nginx/html/index.php

2.下载并解压wordpress.   /usr/share/nginx/html为网站根目录
wget https://cn.wordpress.org/wordpress-6.1.1-zh_CN.tar.gz
tar zxvf wowordpress-6.1.1-zh_CN.tar.gz

3.设置解压后的wordpress文件权限
chmod -R 777 wordpress

4.修改wordpress配置文件
cp wp-config-sample.php wp-config.php //将原配置文件备份
vi wp-config.php
找到文件中 MySQL 的部分，并将相关配置信息修改为 配置 WordPress 数据库 中的内容
// ** MySQL settings - You can get this info from your web host ** //
    /** The name of the database for WordPress */
    define('DB_NAME', 'wordpress');

    /** MySQL database username */
    define('DB_USER', 'user');

    /** MySQL database password */
    define('DB_PASSWORD', '123456');

    /** MySQL hostname */
    define('DB_HOST', 'localhost');

5.将wordpress中的文件全部复制到网站根目录下直接访问ip地址可以安装，否则需要访问对应的文件目录，如http://ip/wordpress
