Linux（LAMP）

赛题拓扑：

题目：

• 安装WEB服务。

• 服务以用户webuser系统用户运行。

• 限制WEB服务只能使用系统500M物理内存。

• 全站点启用TLS访问，使用本机上的"CSK Global Root CA"颁发机构颁发，网站证书信息如下：

  C = CN

  ST = China

  L = BeiJing

  O = skills

  OU = Operations Departments

  CN = *.chinaskills.com

• 客户端访问https时应无浏览器（含终端）安全警告信息。

• 当用户使用http访问时自动跳转到https安全连接。

• 搭建www.chinaskills.cn站点。

• 网页文件放在StorgeSrv服务器上。

• 在StorageSrv上安装MriaDB，在本机上安装PHP，发布WordPress网站。

• MariaDB数据库管理员信息：User: root/ Password: 000000。

  先配置好CA证书颁发机构
  [root@appsrv csk-rootca]# openssl genrsa -out httpd.key 2048
  [root@appsrv csk-rootca]# openssl req -new -key httpd.key -out httpd.csr

  部署数据库：

  [root@storagesrv ~]# mysql_secure_installation
  NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
  SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
  In order to log into MariaDB to secure it, we'll need the current
  password for the root user. If you've just installed MariaDB, and
  you haven't set the root password yet, the password will be blank,
  so you should just press enter here.

  Enter current password for root (enter for none):
  OK, successfully used password, moving on...
  Setting the root password ensures that nobody can log into the MariaDB
  root user without the proper authorisation.

  Set root password? [Y/n] y
  New password: 000000
  Re-enter new password: 000000
  Password updated successfully!
  Reloading privilege tables..
  ... Success!

  By default, a MariaDB installation has an anonymous user, allowing anyone
  to log into MariaDB 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? [Y/n]
  ... 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? [Y/n]
  ... Success!

  By default, MariaDB 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? [Y/n]

  • 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? [Y/n]
  ... Success!

  Cleaning up...
  All done! If you've completed all of the above steps, your MariaDB
  installation should now be secure.
  Thanks for using MariaDB!
