安装apache2
Apache HTTP服务器是世界上使用最广泛的Web服务器。它提供了许多强大的功能，包括可动态加载的模块，强大的媒体支持以及与其他流行软件的广泛集成。

开始安装

打开终端，进入根目录

`renxiaoxu@ubuntu:~$` sudo su

更新环境

renxiaoxu@ubuntu:~$ apt-get upgrade

安装apache环境

renxiaoxu@ubuntu:~$ sudo apt-get install apache

确认安装后， apt将安装Apache和所有必需的依赖项
安装完成之后我们可以在浏览器中输入localhost进行访问
也可以查看apache

renxiaoxu@ubuntu:~$ service apache2 status

看到runing说明成功

**

安装mysql 数据库
安装mysql

renxiaoxu@ubuntu:~$sudo apt-get install my-server

验证 MySQL

renxiaoxu@ubuntu:~$sudo apt-get install my-server
mysql.service - MySQL Community Server

mysql.service - MySQL Community Server
     Loaded: loaded (/lib/systemd/system/mysql.service; enabled; vendor preset:>

             └─1024 /usr/sbin/mysqld

保护加固 MySQL

renxiaoxu@ubuntu:~$ mysql_secure_installation
●Error: Access denied for user 'root'@'localhost'

mysql需要测试 MySQL 用户密码的强度，并且提高安全性

Securing the MySQL server deployment.

Connecting to MySQL using a blank password.

VALIDATE PASSWORD COMPONENT can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD component?

Press y|Y for Yes, any other key for No:

三个级别的密码验证策略，低级，中级，高级

There are three levels of password validation policy:

LOW    Length >= 8
MEDIUM Length >= 8, numeric, mixed case, and special characters
STRONG Length >= 8, numeric, mixed case, special characters and dictionary                  file

Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 2

下一次被提示时，将被要求为 MySQL root 用户设置一个密码：

Please set the password for root here.

New password: 

Re-enter new password

如果你设置了验证密码插件，这个脚本将会显示你的新密码强度。输入y确认密码：

Estimated strength of the password: 50 
Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : y

下一步，你将被要求移除任何匿名用户，限制 root 用户访问本地机器，移除测试数据库并且重新加载权限表。你应该对所有的问题回答y。
以 root 用户身份登录

renxiaoxu@ubuntu:~$ sudo mysql -u root -p

-u 指定用户名 -p需要输入密码

安装 PHP 7.4，配合apache
更新环境

renxiaoxu@ubuntu:~# sudo apt update

安装PHP

renxiaoxu@ubuntu:~# sudo apt install php libapache2-mod-php

php安装好了，重启 Apache，重新加载 PHP 模块

renxiaoxu@ubuntu:# sudo systemctl restart apache2

安装 PHP 扩展
PHP 扩展被编译成库文件，用来扩展 PHP 核心功能
安装 MySQL 和 GD 扩展

renxiaoxu@ubuntu:# sudo apt install php-mysql php-gd

在安装一个新的 PHP 扩展之后，依赖于你的设置，不要忘记去重启 Apache 或者 PHP FPM 服务
测试 PHP 处理
进入/var/www

renxiaoxu@ubuntu:~$ cd /var/www

修改权限

renxiaoxu@ubuntu:~$#sudo chmod 777 /etc/apache2/mods-enabled/dir.conf
bash
renxiaoxu@ubuntu:~$/var/www# cd html/

建立php文件

renxiaoxu@ubuntu:~$/var/www/html# sudo gedit index.php

编辑内容如下

?php
     echo phpinfo();
?>

浏览器输入http://localhost/info.php打开测试页面
至此lamp基本搭建完成

安装depress
修改ssh

进入根目录

sudo su -

修改配置文件

sudo vim /etc/ssh/ssh_config.d/

安装ssh

sudo apt-get install openssh-server

添加ssh.service

sudo systemctl enable ssh.service

启动ssh

service ssh start
sudo apt-get update && apt-get upgrade   //升级更新一下

配置防火墙

sudo ufw app list
sudo ufw allow 'Apache'
进入/var/www/html下创建自己的文件夹

cd /var/www/html/

创建你的项目文件夹

mkdir -p food

用户权限设置

renxiaoxu@ubuntu:~$/var/www/html# sudo chown -R 755 /var/www
修改000-default.conf

1.进入文件夹

renxiaoxu@ubuntu:~$/# cd /etc/apache2/sites-available/

2.备份

renxiaoxu@ubuntu:~$/etc/apache2# sudo cp 000-default.conf 000-food.conf

3.修改

renxiaoxu@ubuntu:~$/etc/apache2/sites-available# sudo nano 000-default.conf

The ServerName directive sets the request scheme, hostname and port that
      # the server uses to identify itself. This is used when creating        # redirection URLs. In the context of virtual hosts, the ServerName        # specifies what hostname must appear in the request's Host: header to        # match this virtual host. For the default virtual host (this file) this        # value is not decisive as it is used as a last resort host regardless.        # However, you must set it for any further virtual host explicitly.        #ServerName www.example.com        ServerAdmin 1052469821@qq.com        ServerName lifeonchina        ServerAlias www.lifeonchina.com        DocumentRoot /var/www/html        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,        # error, crit, alert, emerg.        # It is also possible to configure the loglevel for particular        # modules, e.g.        #LogLevel info ssl:warn

4.修改完后ctrl+x保存退出

5.确认

renxiaoxu@ubuntu:~$/etc/apache2/sites-available# sudo a2ensite 000-default.conf
bash
Site 000-default already enabled       //成功

6.重启apache2，并检查

renxiaoxu@ubuntu:~$/etc/apache2/sites-available# sudo systemctl restart apache2
renxiaoxu@ubuntu:~$/etc/apache2/sites-available# sudo apache2ctl configtest
报错

Set the 'ServerName' directive globally to suppress this message

解决方式

renxiaoxu@ubuntu:~$/etc/apache2/sites-available# sudo nano  /etc/apache2/apache2.conf

编辑配置文件apache.conf

#在文件最后添加一行 ServerName localhost:80 #然后保存并重启Apache2

再测试

service apache2 restart
root@suliu-virtual-machine:/etc/apache2/sites-available# sudo apache2ctl configtest 
Syntax OK.  //成功！

修改完成

1.登陆lmysql

renxiaoxu@ubuntu:/etc/apache2/sites-available# sudo mysql -u root -p

-//输入密码
