MySQL数据库服务器安装与渗透测试指南<\/h1>

一、MySQL数据库服务器安装<\/h2>

1. 安装前准备<\/h3>

确保系统满足MySQL的最低要求<\/li>
准备具有sudo权限的用户账户<\/li>

确保系统已更新到最新版本<\/li> <\/ul>

2. 安装方法<\/h3>

在Ubuntu\/Debian系统上安装：<\/h4>

sudo apt update
<\/span><\/span>sudo apt install mysql-server
<\/span><\/span>sudo systemctl start mysql
<\/span><\/span>sudo systemctl enable mysql
<\/span><\/span><\/code><\/pre>在CentOS\/RHEL系统上安装：<\/h4>
sudo yum install mysql-server
<\/span><\/span>sudo systemctl start mysqld
<\/span><\/span>sudo systemctl enable mysqld
<\/span><\/span><\/code><\/pre>3. 安全配置<\/h3>
运行MySQL安全安装脚本：<\/p>
sudo mysql_secure_installation
<\/span><\/span><\/code><\/pre>此脚本将引导您完成以下配置：<\/p>

设置root密码<\/li>
移除匿名用户<\/li>
禁止root远程登录<\/li>
移除测试数据库<\/li>
重新加载权限表<\/li>
<\/ul>
4. 验证安装<\/h3>
mysql --version
<\/span><\/span>sudo systemctl status mysql

<\/span><\/span>def<\/span> receive_ftp_banner<\/span>(sock):
<\/span><\/span>    data =<\/span> sock.<\/span>recv(1024<\/span>)
<\/span><\/span>    print(data)
<\/span><\/span>
<\/span><\/span>mysession.<\/span>pre_send =<\/span> receive_ftp_banner

可以通过网页界面(http:\/\/127.0.0.1:26000)查看当前测试状态<\/p>
四、Jenkins服务器渗透测试<\/h2>
1. Jenkins安装<\/h3>
基本要求：<\/h4>

Java 7或更高版本(推荐Java 8)<\/li>
至少512MB RAM<\/li>
<\/ul>
安装步骤：<\/h4>

下载Jenkins.war文件<\/li>
运行命令启动Jenkins：<\/li>
<\/ol>
java -jar jenkins.war
<\/span><\/span><\/code><\/pre>
在浏览器中访问http:\/\/localhost:8080完成安装<\/li>
<\/ol>
安装日志关键信息：<\/h4>
INFO: Jenkins initial setup is required. An admin user has been created and a password generated.
Please use the following password to proceed to installation:
e019dca34bac4a30beca67b53e821f35
This may also be found at: \/root\/.jenkins\/secrets\/initialAdminPassword
<\/code><\/pre>
2. Jenkins常见漏洞<\/h3>

未授权访问漏洞<\/li>

凭证信息泄露<\/li>
插件漏洞<\/li>
<\/ol>
五、SQL注入测试示例<\/h2>
1. 注入点识别<\/h3>
当URL参数直接用于数据库查询时可能存在注入漏洞，例如：<\/p>
http:\/\/192.168.2.105\/home.php?search=tom@gmail.com&Search=Search
<\/code><\/pre>
2. 测试方法<\/h3>

添加单引号测试：tom@gmail.com'<\/code><\/li>
使用布尔测试：tom@gmail.com' AND 1=1 -- <\/code><\/li>
使用时间延迟测试：tom@gmail.com' AND (SELECT * FROM (SELECT(SLEEP(5)))bAKL) -- <\/code><\/li>
<\/ol>
3. 信息提取技术<\/h3>

使用UNION查询提取数据<\/li>
使用基于错误的提取技术<\/li>
使用基于时间的盲注技术<\/li>
使用外带数据技术(OOB)<\/li>
<\/ol>
六、安全建议<\/h2>
1. MySQL安全加固<\/h3>

定期更新MySQL到最新版本<\/li>
限制远程访问<\/li>
使用最小权限原则<\/li>
加密敏感数据<\/li>
定期审计数据库权限<\/li>
<\/ol>
2. FTP服务器安全<\/h3>

禁用匿名登录<\/li>
使用SFTP替代FTP<\/li>
限制用户目录<\/li>
启用日志记录<\/li>
定期更新软件<\/li>
<\/ol>
3. Jenkins安全<\/h3>

启用身份验证<\/li>
限制脚本控制台访问<\/li>
定期更新Jenkins和插件<\/li>
使用角色矩阵控制权限<\/li>
定期备份配置和数据<\/li>
<\/ol>
本指南涵盖了从基础安装到高级渗透测试技术的全面内容，适用于安全研究人员和系统管理员进行安全评估和加固。<\/p>
