CentOS7 下 yum 安装 nginx + php + mysql 及管理

1、使用yum安装Nginx

  yum install nginx

2、启动Nginx服务

  systemctl start nginx

  注：此时浏览器访问IP即可访问Nginx默认页面

3、使用yum安装php

  yum install php

4、使用yum安装php相关扩展

  yum install php-fpm php-mysql php-xml php-mbstring php-openssl php-gd php-pecl-zip

5、使用yum安装mysql

  rpm -Uvh http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm

  yum install mysql-community-server

  yum install mysql-community-client

6、配置Nginx

  学习 vi 的基本操作

  使用vi编辑/etc/nginx/conf.d/default.conf文件

  vi /etc/nginx/conf.d/default.conf

  在最上面添加如下代码并保存：

  server
  {
      listen 80;
      #listen 443 ssl;
      server_name 127.0.0.1 localhost;
      index index.php index.html index.htm default.php default.htm default.html;
      root /www/website/public;

      #SSL-START SSL相关配置，请勿删除或修改下一行带注释的404规则
      #error_page 404/404.html;
      #ssl                on;
      #ssl_certificate    /www/nginx/conf.d/cert/1_oa.jltengfang.com_bundle.crt;
      #ssl_certificate_key    /www/nginx/conf.d/cert/2_oa.jltengfang.com.key;
      #if ($server_port !~ 443){
      #    rewrite ^(/.*)$ https://$hostphp permanent;
      #}
      #error_page 497  https://$host$request_uri;
      #SSL-END

      #ERROR-PAGE-START  错误页配置，可以注释、删除或修改
      #error_page 404 /404.html;
      #error_page 502 /502.html;
      #ERROR-PAGE-END

      #跨域请求设置
      add_header 'Access-Control-Allow-Origin' '*';
      add_header 'Access-Control-Allow-Credentials' 'true';
      add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
      add_header 'Access-Control-Allow-Headers' 'accept, content-type,UserToken,Flag';

      #Thinkphp的URL重写规则
      if (!-e $request_filename) {
          rewrite  ^(.*)$  /index.php?s=/$1  last;
          break;
      }

      #PHP-INFO-START  PHP引用配置，可以注释或修改
      #include enable-php-71.conf;
      location ~ [^/]\.php(/|$)
      {
          try_files $uri =404;
          # fastcgi_pass  unix:/tmp/php-cgi-71.sock;
          fastcgi_pass 127.0.0.1:9000;
          fastcgi_index index.php;

          # FastCGI
          fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
          fastcgi_param  QUERY_STRING       $query_string;
          fastcgi_param  REQUEST_METHOD     $request_method;
          fastcgi_param  CONTENT_TYPE       $content_type;
          fastcgi_param  CONTENT_LENGTH     $content_length;

          fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
          fastcgi_param  REQUEST_URI        $request_uri;
          fastcgi_param  DOCUMENT_URI       $document_uri;
          fastcgi_param  DOCUMENT_ROOT      $document_root;
          fastcgi_param  SERVER_PROTOCOL    $server_protocol;
          fastcgi_param  HTTPS              $https if_not_empty;

          fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
          fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

          fastcgi_param  REMOTE_ADDR        $remote_addr;
          fastcgi_param  REMOTE_PORT        $remote_port;
          fastcgi_param  SERVER_ADDR        $server_addr;
          fastcgi_param  SERVER_PORT        $server_port;
          fastcgi_param  SERVER_NAME        $server_name;

          # PHP only, required if PHP was built with --enable-force-cgi-redirect
          fastcgi_param  REDIRECT_STATUS    200;
    
          # PATHINFO
          set $real_script_name $fastcgi_script_name;
          if ($fastcgi_script_name ~ "^(.+?\.php)(/.+)$") {
              set $real_script_name $1;
              set $path_info $2;
          }
          fastcgi_param SCRIPT_FILENAME $document_root$real_script_name;
          fastcgi_param SCRIPT_NAME $real_script_name;
          fastcgi_param PATH_INFO $path_info;
      }
      #PHP-INFO-END

      location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
      {
          expires      30d;
          access_log off; 
      }

      location ~ .*\.(js|css)?$
      {
          expires      12h;
          access_log off; 
      }
      access_log  /www/nginx/log/php.log;
  }

7、运行PHP

  systemctl restart nginx

  systemctl start php-fpm

  systemctl start mysqld

8、MySql初始设置

  使用cat /var/log/mysqld.log查看Root初始化密码

  登入MySQL：

      mysql -uroot -p

  使用以下命令设置root密码：

      SET GLOBAL validate_password_policy=0;

      SET GLOBAL validate_password_length=4;

      SET PASSWORD = PASSWORD('新密码');

  为MySQL的root用户添加远程登录授权：

      GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '密码' WITH GRANT OPTION;

  重启MySQL：

      systemctl restart mysqld
