Server built: 2019-12-03T15:55:03还需要设置 Apache 跟随系统启动：
sudo systemctl enable apache2.service如果我们在浏览器上访问云服务器的 IP 地址 http://IPAddress，出现 Apache 的默认页面，就说明 Apache 已经安装成功了。
安装 PHP
通过以下命令安装 PHP：
sudo apt-get install php -y接下来，安装必要的 PHP 扩展：
sudo apt-get install php-{bcmath,bz2,intl,gd,mbstring,mysql,fpm} -y通过以下命令查看 PHP 的版本：

Zend OPcache安装 MySQL
通过以下命令安装 MySQL：
sudo apt-get install mysql-server -y通过以下命令查看 MySQL 的版本：
mysql -V显示结果如下：
mysql Ver 14.14 Distrib 5.7.29, for Linux (x86_64) using EditLine wrapper然后，运行 MySQL 安装配置向导：
sudo mysql_secure_installation在 MySQL 安装配置向导中，我们需要输入 root 密码，并回答一些安全性相关的问题，通常只需要选择向导提供的默认值即可。
Securing the MySQL server deployment.
Connecting to MySQL using a blank password.
VALIDATE PASSWORD PLUGIN 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 plugin?
Press y|Y for Yes, any other key for No: Y
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
Please set the password for root here.
New password:
Re-enter new password:
Estimated strength of the password: 100
Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : Y
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
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
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
- 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
Success.
All done!还需要设置 MySQL 跟随系统启动：
sudo systemctl enable mysql.service设置 UFW
默认情况下，Ubuntu 的防火墙 UFW 是禁用状态的。我们需要启用 UFW，并允许 SSH 和 Apache 相关端口的访问。
sudo ufw allow OpenSSH
sudo ufw allow in Apache Full
sudo ufw enable以上就是关于“Ubuntu 怎么安装 Apache、PHP 和 MySQL”这篇文章的内容，相信大家都有了一定的了解，希望丸趣 TV 小编分享的内容对大家有帮助，若想了解更多相关的知识内容，请关注丸趣 TV 行业资讯频道。
