更新操作系統
在安裝之前，我們更新操作系統到最新版本，并重啟云服務器。
sudo apt-get update -y
sudo apt-get upgrade -y
reboot安裝 Apache
通過以下命令安裝 Apache：
sudo apt-get install apache2 -y通過以下命令查看 Apache 的版本：
apache2 -v顯示結果如下：
Server version: Apache/2.4.29 (Ubuntu)
Server built: 2019-12-03T15:55:03還需要設置 Apache 跟隨系統啟動：
sudo systemctl enable apache2.service如果我們在瀏覽器上訪問云服務器的 IP 地址 http://IPAddress，出現 Apache 的默認頁面，就說明 Apache 已經安裝成功了。
安裝 PHP
通過以下命令安裝 PHP：
sudo apt-get install php -y接下來，安裝必要的 PHP 擴展：
sudo apt-get install php-{bcmath,bz2,intl,gd,mbstring,mysql,fpm} -y通過以下命令查看 PHP 的版本：
php -v顯示結果如下：
PHP 7.2.24-0ubuntu0.18.04.3 (cli) (built: Feb 11 2020 15:55:52) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies
with Zend OPcache v7.2.24-0ubuntu0.18.04.3, Copyright (c) 1999-2018, by Zend Technologies通過以下命令查看 PHP 安裝的模塊：
php -m顯示結果如下：
[PHP Modules]
bcmath
calendar
ctype
fileinfo
filter
gettext
iconv
libxml
mbstring
mysqli
mysqlnd
openssl
pcntl
pdo_mysql
posix
readline
Reflection
session
shmop
sockets
sodium
standard
sysvmsg
sysvsem
sysvshm
tokenizer
Zend OPcache
[Zend Modules]
Zend OPcache安裝 MySQL
通過以下命令安裝 MySQL：
sudo apt-get install mysql-server -y通過以下命令查看 MySQL 的版本：
mysql -V顯示結果如下：
mysql Ver 14.14 Distrib 5.7.29, for Linux (x86_64) using EditLine wrapper然后，運行 MySQL 安裝配置向導：
sudo mysql_secure_installation在 MySQL 安裝配置向導中，我們需要輸入 root 密碼，并回答一些安全性相關的問題，通常只需要選擇向導提供的默認值即可。
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!還需要設置 MySQL 跟隨系統啟動：
sudo systemctl enable mysql.service設置 UFW
默認情況下，Ubuntu 的防火墻 UFW 是禁用狀態的。我們需要啟用 UFW，并允許 SSH 和 Apache 相關端口的訪問。
sudo ufw allow OpenSSH
sudo ufw allow in Apache Full
sudo ufw enable以上就是關于“Ubuntu 怎么安裝 Apache、PHP 和 MySQL”這篇文章的內容，相信大家都有了一定的了解，希望丸趣 TV 小編分享的內容對大家有幫助，若想了解更多相關的知識內容，請關注丸趣 TV 行業資訊頻道。
