Linux（LAMP）

赛题拓扑：

标题：

• 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时应无欣赏器（含终端）安全警告信息。
  
• 当用户使用http访问时主动跳转到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。

85. [root@appsrv ~]# ls /webdata/
86. wordpress  wordpress-4.9.4-zh_CN.zip
87. 部署数据库：
88. [root@storagesrv ~]# systemctl start mariadb
89. [root@storagesrv ~]# mysql_secure_installation
90. NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
91.       SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!
92. In order to log into MariaDB to secure it, we'll need the current
93. password for the root user.  If you've just installed MariaDB, and
94. you haven't set the root password yet, the password will be blank,
95. so you should just press enter here.
97. Enter current password for root (enter for none):
98. OK, successfully used password, moving on...
99. Setting the root password ensures that nobody can log into the MariaDB
100. root user without the proper authorisation.
102. Set root password? [Y/n] y                           
103. New password: 000000
104. Re-enter new password: 000000
105. Password updated successfully!
106. Reloading privilege tables..
107. ... Success!
109. By default, a MariaDB installation has an anonymous user, allowing anyone
110. to log into MariaDB without having to have a user account created for
111. them.  This is intended only for testing, and to make the installation
112. go a bit smoother.  You should remove them before moving into a
113. production environment.
115. Remove anonymous users? [Y/n]
116. ... Success!
118. Normally, root should only be allowed to connect from 'localhost'.  This
119. ensures that someone cannot guess at the root password from the network.
121. Disallow root login remotely? [Y/n]
122. ... Success!
124. By default, MariaDB comes with a database named 'test' that anyone can
125. access.  This is also intended only for testing, and should be removed
126. before moving into a production environment.
128. Remove test database and access to it? [Y/n]
129. - Dropping test database...
130. ... Success!
131. - Removing privileges on test database...
132. ... Success!
134. Reloading the privilege tables will ensure that all changes made so far
135. will take effect immediately.
137. Reload privilege tables now? [Y/n]
138. ... Success!
140. Cleaning up...
141. All done!  If you've completed all of the above steps, your MariaDB
142. installation should now be secure.
143. Thanks for using MariaDB!
145. [root@storagesrv ~]# mysql -u root -p
146. Enter password:
147. Welcome to the MariaDB monitor.  Commands end with ; or \g.
148. Your MariaDB connection id is 14
