Apache Tomcat/7.0.21
解决方法:
先进入manager所在目录
[root@localhost tomcat]# cd webapps/manager/WEB-INF/
查看 web.xml
[root@localhost WEB-INF]# more web.xml
<!-- Define a Security Constraint on this Application --> <!-- NOTE: None of these roles are present in the default users file --> <security-constraint> <web-resource-collection> <web-resource-name>HTML Manager interface (for humans)</web-resource-name> <span> <url-pattern>/html/*</url-pattern> 对应:http://localhost:8080/manager/html</span> </web-resource-collection> <auth-constraint> <span> <role-name>manager-gui</role-name> 定义了访问这个页面的角色名:manage-gui</span> </auth-constraint> </security-constraint> <security-constraint> <web-resource-collection> <web-resource-name>Text Manager interface (for scripts)</web-resource-name> <url-pattern>/text/*</url-pattern> </web-resource-collection> <auth-constraint> <role-name>manager-script</role-name> </auth-constraint> </security-constraint> <security-constraint> <web-resource-collection> <web-resource-name>JMX Proxy interface</web-resource-name> <url-pattern>/jmxproxy/*</url-pattern> </web-resource-collection> <auth-constraint> <role-name>manager-jmx</role-name> </auth-constraint> </security-constraint> <security-constraint> <web-resource-collection> <web-resource-name>Status interface</web-resource-name> <span> <url-pattern>/status/*</url-pattern> 对应:http://localhost:8080/manager/status </span> </web-resource-collection> <auth-constraint> <span> <role-name>manager-gui</role-name> </span> <role-name>manager-script</role-name> <role-name>manager-jmx</role-name> <role-name>manager-status</role-name> </auth-constraint> </security-constraint>
进入host-manager所在目录
[root@localhost tomcat]# cd webapps/host-manager/WEB-INF/
查看 web.xml
[root@localhost WEB-INF]# more web.xml
<security-constraint> <web-resource-collection> <web-resource-name>HTMLHostManager commands</web-resource-name> <url-pattern><span>/html/*</span></url-pattern> <span>对应:<span>http://192.168.14.219:8080/host-manager/</span>htm</span>l </web-resource-collection> <auth-constraint> <!-- NOTE: This role is not present in the default users file --> <span> <role-name>admin-gui</role-name> 定义了管理角色名称</span></auth-constraint> </security-constraint>
<!-- Security roles referenced by this web application --> <security-role> <description> <span>The role that is required to log in to the Host Manager Application HTML</span> <span> interface</span> </description> <span><role-name>admin-gui</role-name></span> </security-role> <security-role> <description> The role that is required to log in to the Host Manager Application text interface </description> <role-name>admin-script</role-name> </security-role>
编辑Tomcat用户配置文件,添加角色
[root@localhost tomcat]# vi conf/tomcat-users.xml
<tomcat-users> <!-- NOTE: By default, no user is included in the "manager-gui" role required to operate the "/manager/html" web application. If you wish to use this app, you must define such a user - the username and password are arbitrary. --> <!-- NOTE: The sample user and role entries below are wrapped in a comment and thus are ignored when reading this file. Do not forget to remove <!.. ..> that surrounds them. --> <span><!-- 这里有个注释符号去掉,使下面的生效</span> <role rolename="tomcat"/> <role rolename="role1"/> <!--添加管理页面访问角色--> <span> <role rolename="manager-gui"></role> </span> <span> <role rolename="admin-gui"></role></span> <span><user username="manager" password="manager" roles="manager-gui,admin-gui">> <user username="tomcat" password="tomcat" roles="tomcat"></user> <user username="both" password="tomcat" roles="tomcat,role1"></user> <user username="role1" password="tomcat" roles="role1"></user> <span>--> 这里有个注释符号去掉,是下面的生效</span> </user></span></span></tomcat-users>
重启 tomcat
[root@localhost tomcat]# ./bin/shutdown.sh
[root@localhost tomcat]# ./bin/startup.sh
总结:
虚拟目录/WEB-INF/web.xml一般定义了访问这个目录的安全角色名称,得知这个安全角色名称后便可在conf/tomcat-users.xml添加对应的访问角色,获得访问权限。(于是这里也是个黑客可以利用的后门。。。)

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.

The best tools and technologies for automating the creation of users in MySQL include: 1. MySQLWorkbench, suitable for small to medium-sized environments, easy to use but high resource consumption; 2. Ansible, suitable for multi-server environments, simple but steep learning curve; 3. Custom Python scripts, flexible but need to ensure script security; 4. Puppet and Chef, suitable for large-scale environments, complex but scalable. Scale, learning curve and integration needs should be considered when choosing.
