Yêu cầu:
- CentOS 5.x 32 bit va 64 bit / CentOS 6.x 32 bit va 64 bit
- VPS sử dụng: Nginx, php-fpm, mysql (MariaDB cũng được)
1. Tạo user, home dir , virtualhost, phân quyền
a. Tạo user
- Để tạo thêm user ngoài user root các bạn dùng lệnh:
Mã:
useradd -s /sbin/nologin tên-user
tên-user: tên user muốn tạo
- Tiếp theo đặt pass cho user
Mã:
passwd tên-user
đơn giản là để bảo mật nên thế và cứ gõ rồi enter là xong.b. Tạo home dir
Để tạo home dir các bạn chạy lệnh như sau:
Mã:
mkdir -p /home/tên-user/public_html
Mã:
mkdir /home/tên-user/logs
Mã:
chown -R tên-user:tên-user /home/tên-user
Mã:
chmod 711 /home/tên-user
* Tạo file vhost (virtualhost)
Truy cập thư mục: /etc/nginx/conf.d/ tạo 1 file tên-user.conf với nội dung
Mã:

Mã:
service vsftpd start
Done giờ bạn đã có 1 con vps nginx với mỗi user tương ứng với mỗi domain, và các user này sẽ chỉ truy cập được vào FPT qua cổng 21 và chỉ quản lý được các file trong thư mục user của mình
