手工搭建LNMP环境（Huawei Cloud EulerOS 2.0）
操作步骤
安装Nginx
登录弹性云服务器。
执行以下命令，安装Nginx。
sudo yum -y install nginx
执行以下命令，验证Nginx的安装版本。
nginx -v
回显如下类似信息：
nginx version: nginx/1.21.5
执行以下命令，启动Nginx并设置开机启动。
systemctl start nginx
systemctl enable nginx
查看启动状态。
systemctl status nginx.service
回显如下类似信息。
使用浏览器访问 “http://服务器IP地址”，显示如下页面，说明Nginx安装成功。
图1 测试访问Nginx
安装MySQL
依次执行以下命令，安装MySQL。
mkdir mysql-server
cd mysql-server
wget https://repo.huaweicloud.com/hce/2.0/os/x86_64/Packages/mysql-8.0.28-1.hce2.x86_64.rpm
yum install mysql-server
依次执行以下命令，启动MySQL服务并设置开机自启动。
systemctl start mysqld
systemctl enable mysqld
查看MySQL运行状态。
systemctl status mysqld.service
回显如下类似信息。
执行以下命令，并按照回显提示信息进行操作，加固MySQL。
mysql_secure_installation
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 : Y
There are three levels of password validation policy:
LOW Length >= 8
MEDIUM Length >= 8, numeric, mixed case, and special characters
SERONG 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: #设置新的root用户密码
Re-enter new password: #再次输入密码
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 #确认使用已设置的密码，输入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 #是否删除匿名用户，输入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 #禁止root远程登录，输入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 #是否删除test库和对它的访问权限，输入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 #是否重新加载授权表，输入Y
Success.
All done!
执行以下命令，退出当前文件夹。
cd ~
安装PHP
依次执行以下命令，安装PHP 8。
wget https://repo.huaweicloud.com/hce/2.0/os/x86_64/Packages/php-8.0.0-10.hce2.x86_64.rpm
yum install php-8.0.0-10.hce2.x86_64.rpm
执行以下命令，验证PHP的安装版本。
php -v
回显如下类似信息：
执行以下命令，启动PHP服务并设置开机自启动。
systemctl start php-fpm
systemctl enable php-fpm
修改Nginx配置文件以支持PHP。
-
执行以下命令打开Nginx配置文件。
vim /etc/nginx/nginx.conf -
按i键进入编辑模式。
-
修改打开的“nginx.conf”文件。
找到server段落，修改或添加下列配置信息。
server { listen 80; listen [::]:80; server_name _; root /usr/share/nginx/html; # Load configuration files for the default server block. include /etc/nginx/default.d/*.conf; location / { index index.php index.html index.htm; } location ~ .php$ { root /usr/share/nginx/html; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; }如图2所示：
图2 修改后截图
-
按Esc键退出编辑模式，并输入**:wq**保存后退出。
执行以下命令，重新载入Nginx的配置文件。
service nginx reload
浏览器访问测试。
在/usr/share/nginx/html/目录下创建“info.php”的测试页面。
-
执行以下命令创建并打开“info.php”的测试文件。
**vim /usr/share/nginx/html/**info.php
-
按i键进入编辑模式。
-
修改打开的“info.php”文件，将如下内容写入文件。
<?php phpinfo(); ?> -
按Esc键退出编辑模式，并输入**:wq**保存后退出。
使用浏览器访问“http://服务器IP地址/info.php”，显示如下页面，说明环境搭建成功。
