在安裝之前，我們更新操作系統(tǒng)到最新版本，并重啟云服務(wù)器。
sudo apt-get update -y sudo apt-get upgrade -y reboot
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(jié)果如下：
Server version: Apache/2.4.29 (Ubuntu) Server built: 2019-12-03T15:55:03
還需要設(shè)置Apache跟隨系統(tǒng)啟動(dòng)：
sudo systemctl enable apache2.service
如果我們?cè)跒g覽器上訪問云服務(wù)器的IP地址 http://IPAddress ，出現(xiàn)Apache的默認(rèn)頁(yè)面，就說明Apache已經(jīng)安裝成功了。
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(kuò)展：
重慶分公司
重慶分公司
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(jié)果如下：

通過以下命令查看PHP安裝的模塊：
php -m
顯示結(jié)果如下：

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(jié)果如下：
mysql Ver 14.14 Distrib 5.7.29, for Linux (x86_64) using EditLine wrapper
然后，運(yùn)行MySQL安裝配置向?qū)В?/p>
sudo mysql_secure_installation
在MySQL安裝配置向?qū)е?，我們需要輸入root密碼，并回答一些安全性相關(guān)的問題，通常只需要選擇向?qū)峁┑哪J(rèn)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(shè)置MySQL跟隨系統(tǒng)啟動(dòng)：
sudo systemctl enable mysql.service
默認(rèn)情況下，Ubuntu的防火墻UFW是禁用狀態(tài)的。我們需要啟用UFW，并允許SSH和Apache相關(guān)端口的訪問。
sudo ufw allow OpenSSH sudo ufw allow in "Apache Full" sudo ufw enable
