Centos7安装PHP及Nginx的教程详解

针对CentOS7安装PHP及Nginx的教程，可以按照以下步骤进行操作：

安装Nginx

1. 更新系统软件包

yum update

1. 安装EPEL源

yum install epel-release

1. 安装Nginx

yum install nginx

1. 启动Nginx服务，并设置开机启动

systemctl start nginx
systemctl enable nginx

安装PHP

1. 安装PHP及相关扩展

yum install php php-fpm php-mysqlnd php-pdo php-pecl-memcached php-pgsql php-gd

1. 配置php-fpm服务

systemctl start php-fpm
systemctl enable php-fpm

1. 配置php-fpm的pool

配置Nginx与PHP-FPM

1. 配置Nginx的虚拟主机

“`
server {
listen 80;
server_name example.com;
root /usr/share/nginx/html;
index index.php index.html index.htm;

   location / {
       try_files $uri $uri/ /index.php?$args;
   }

   location ~ \.php$ {
       fastcgi_pass  unix:/var/run/php-fpm/php-fpm.sock;
       fastcgi_index index.php;
       fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
       include       fastcgi_params;
   }

}
“`

1. 重启Nginx

systemctl restart nginx

至此，CentOS7上Nginx及PHP安装并配置完成。可以在PHP-FPM的pool中设置不同的用户和组权限，来实现更严格的文件权限控制。

示例1：在Nginx上部署WordPress博客

1. 安装WordPress及相关扩展

yum install php-mysqlnd php-gd php-xml
wget https://wordpress.org/latest.tar.gz
tar -xzvf latest.tar.gz
mv wordpress /usr/share/nginx/html/

1. 配置WordPress的数据库

创建数据库并授权给一个新的用户：

mysql -u root -p
create database mywp;
grant all privileges on mywp.* to mywpuser@localhost identified by 'mypassword';
exit

修改WordPress配置文件wp-config.php以保证与数据库连接：

“`
/
* MySQL settings – You can get this info from your web host
*/
/ The name of the database for WordPress */
define(‘DB_NAME’, ‘mywp’);

/* MySQL database username /
define(‘DB_USER’, ‘mywpuser’);

/* MySQL database password /
define(‘DB_PASSWORD’, ‘mypassword’);

/* MySQL hostname /
define(‘DB_HOST’, ‘localhost’);
“`

1. 访问博客前台

访问http://your_domain/wp-admin/install.php 进行WordPress的初始化配置，配置完成后即可正常访问博客前台。

示例2：在Nginx上部署Laravel应用

1. 安装Laravel及相关扩展

yum install php-mbstring php-xml php-tokenizer php-zip
composer create-project --prefer-dist laravel/laravel myapp
mv myapp /usr/share/nginx/html/

1. 配置Laravel的APP_KEY

php artisan key:generate

1. 配置Nginx的虚拟主机

“`
server {
listen 80;
server_name myapp.example.com;
root /usr/share/nginx/html/myapp/public;
index index.php;

   location / {
       try_files $uri $uri/ /index.php?$query_string;
   }

   location ~ \.php$ {
       fastcgi_pass  unix:/var/run/php-fpm/php-fpm.sock;
       fastcgi_index index.php;
       fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
       include       fastcgi_params;
   }

}
“`

1. 重启Nginx

systemctl restart nginx

现在，就可以访问http://myapp.example.com来访问Laravel应用了。
