windows下Ubuntu安装 Lnmp环境

安装 Nginx

1. 安装Nginx
   

   sudo apt install nginx -y

2. 启动并使 Nginx 在启动时自动启动
   

   sudo systemctl start nginx
   sudo systemctl enable nginx

    

    

    

安装Mysql5.7 

一：先卸载并清理历史的Mysql环境

• 首先，停止Mysql服务
  

  sudo systemctl stop mysql

• 然后，通过apt-get命令移除MySQL包
  

  sudo apt-get remove --purge mysql-server mysql-client mysql-common

• 清理残余的配置和数据文件
  

  sudo rm -rf /etc/mysql /var/lib/mysql
  sudo apt-get autoremove
  sudo apt-get autoclean

• 如果你之前安装了其他非官方的MySQL版本或是MariaDB，也可以一并卸载
  

  sudo apt-get remove --purge mysql-server-core-*

二：安装 Mysql5.7版本的环境

1. 更新软件包列表
   

   sudo apt-get update

2. 查看系统默认安装的数据库版本
   执行命令：
   

   sudo apt-cache policy mysql-server

   

3. 需要安装mysql5.7的版本就需要换源
   先备份文件：
   

   sudo cp /etc/apt/sources.list /etc/apt/sources.list.back

   然后更换apt源：修改sources.list文件
   

   sudo vim /etc/apt/sources.list

   #  阿里源
   deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
   deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
   deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
   deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
   deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
   deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
   deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
   deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
   deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
   deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

   

4. 更新镜像源
   

   sudo gpg --keyserver keyserver.ubuntu.com --recv 3B4FE6ACC0B21F32
   sudo gpg --export --armor 3B4FE6ACC0B21F32 | sudo apt-key add -
   sudo apt-get update

5. 查看默认安装的mysql数据库版本,可以看到默认的已经变成了mysql5.7的版本了哦！
   
   
   
   
6. 安装Mysql5.7
   

   sudo apt-get -y install mysql-server-5.7

7. 查看mysql是否安装成功
   

   sudo dpkg -l | grep mysql
   mysql -V
   sudo systemctl status mysql

   

8.  

   设置开机自启
   

   sudo systemctl enable mysql

9. 修改服务为全网启动
   打开mysql的配置文件：/etc/mysql/mysql.conf.d/mysqld.cnf
   
   
   
10. 换回apt源
    

    cd /etc/apt
    sudo mv sources.list sources.list.old
    sudo mv sources.list.back  sources.list
    sudo apt-get update

11. 进入mysql终端
    输入 sudo mysql  回车，默认是没有密码的哦！
    
    
12. 设置允许远程访问
    

    use mysql;
    update user set host='%' where user = 'root' and host='localhost';
    grant all privileges on *.* to 'root'@'%' identified by 'root' with grant option;
    flush privileges;

     

安装php7.4

1. 为了安装 PHP 7.4，我们可以使用 ondrej/php PPA：
   

   sudo apt install software-properties-common -y
   sudo add-apt-repository ppa:ondrej/php
   sudo apt update

2. 安装 PHP 7.4 以及与 Nginx 和 MySQL 相关的一些常用扩展
   

   sudo apt install php7.4 php7.4-fpm php7.4-mysql php7.4-cli php7.4-fpm php7.4-json php7.4-common php7.4-mbstring php7.4-zip php7.4-gd php7.4-mysqli -y

   如果是 PHP8.4的话：

   sudo apt install php8.4 php8.4-cli php8.4-common php8.4-mbstring php8.4-xml php8.4-mysql php8.4-curl php8.4-gd -y

3. 启动并使 PHP 7.4 FPM 在启动时自动启动
   

   sudo systemctl start php7.4-fpm
   sudo systemctl enable php7.4-fpm
