3、集成NGIN+PHP
vi /etc/nginx/conf.d/default.conf

server {
  server_name domain.com www.domain.com;

  location / {
    root /www/htdocs;
    index index.php index.html index.htm;
  }

  location ~ \.php$ {
    root /www/htdocs;
    fastcgi_pass 127.0.0.1:9000;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
  }

  error_page 404 /404.html;
  location = /404.html {
  }

  error_page 500 502 503 504 /50x.html;
  location = /50x.html {
  }

  listen 443 ssl;
  ssl_certificate /etc/nginx/certs/domain.com/cert.pem;
  ssl_certificate_key /etc/nginx/certs/domain.com/key.pem;
}

server {
  if ($host = www.domain.com) {
    return 301 https://$host$request_uri;
  }

  listen 80;
  server_name domain.com www.domain.com;
  return 404;
}

4、安装mysql8.0
在MySQL官网中获取YUM源rpm包地址

yum localinstall mysql80-community-release-el7-4.noarch.rpm
yum clean all
yum makecache

安装mysql
yum install mysql-community-server

编辑配置
vi /etc/my.cnf

启动mysql
