Kali linux 2020.3 GVM使用
安装GVM
老版本的openvas只需要我们执行apt-get install openvas即可完成自动化的安装，新版本中需要我们手动安装GVM以及它的其他组件。
查看Kali版本
在安装前先看一下Kali的版本：
# uname -a 127 ↵
Linux F0rGeEk 5.10.0-kali7-amd64 #1 SMP Debian 5.10.28-1kali1 (2021-04-12) x86_64 GNU/Linux
安装组件
需要安装的组件有：
apt-get install gvmd gvmd-common gvmd-dbgsym
初始化
安装完成之后可以通过gvm-setup进行初始化：
# gvm-setup
ERROR: The default postgresql version is not 13 required by libgvmd
Error: Use pg_upgradecluster to update your postgres cluster
分析报错信息
通过执行初始化命令后，发现有报错信息无法进行初始化配置。分析报错信息可知，主要原因是postgresql版本的问题导致无法进行初始化。
查看postgresql版本
通过dpkg -l | grep postgresql 可以查看当前系统中安装的postgresql是什么版本：
# dpkg -l | grep postgresql 1 ↵
ii postgresql 13+225 all object-relational SQL database (supported version)
ii postgresql-11 11.6-2~sid1 amd64 object-relational SQL database, version 11 server
ii postgresql-12 12.4-3 amd64 object-relational SQL database, version 12 server
ii postgresql-13 13.2-1 amd64 The World\'s Most Advanced Open Source Relational Database
ii postgresql-client-11 11.6-2~sid1 amd64 front-end programs for PostgreSQL 11
ii postgresql-client-12 12.4-3 amd64 front-end programs for PostgreSQL 12
ii postgresql-client-13 13.2-1 amd64 front-end programs for PostgreSQL 13
ii postgresql-client-common 225 all manager for multiple PostgreSQL client versions
ii postgresql-common 225 all PostgreSQL database-cluster manager
通过查看可知，kali默认是在原有postgresql基础上进行更新，并且保留了历史版本。我这里有三个版本11、12、13，通过执行pg_lsclusters可以得知这三个版本的postgresql都在运行。新版本postgresql通过在默认5432这个端口的基础上进行累加从而避免端口占用。
查看postgresql监听端口
# pg_lsclusters
Ver Cluster Port Status Owner Data directory Log file
11 main 5432 online postgres /var/lib/postgresql/11/main /var/log/postgresql/postgresql-11-main.log
12 main 5433 online postgres /var/lib/postgresql/12/main /var/log/postgresql/postgresql-12-main.log
13 main 5434 online postgres /var/lib/postgresql/13/main /var/log/postgresql/postgresql-13-main.log
通过上述情况来看可以分析，GVM在启动的时候会去使用postgresql的默认端口5432去连接它，并且通过这个连接来判断当前postgresql版本。如果版本低于13则无法正常启动，因为GVM是基于postgresql 13 这个版本的。
经过一番查找发现，这是Kali2020.3这个版本的一个bug。官方也有人提过这个bug，当然也给出了解决方案。感兴趣的朋友可以根据bug编号去查看处理过程。
报错解决过程
过程综述
整个解决过程分为以下6步，每个步骤执行的详细过程下文会单独贴出来。
1. 停止pg_clusters
sudo pg_dropcluster 12 main --stop
sudo pg_dropcluster 13 main --stop
2. 确定所有clusters已停止
sudo pg_lsclusters
3. 重新执行gvm setup
sudo gvm-check-setup
4. 创建V13版本的pgsql并启动
sudo pg_createcluster 13 main
sudo pg_ctlcluster 13 main start
5. 操作pqsql数据库并创建用户
sudo runuser -u postgres -- /usr/share/gvm/create-postgresql-database
sudo runuser -u _gvm -- gvmd --create-user=admin --password=<your_password_not_mine_obviously>
6. 最后检查状态
sudo gvm-check-setup
sudo gvm-start
执行gvm-check-setup
首先执行gvm-check-setup，看看具体报错信息
gvm-check-setup
gvm-check-setup 20.8.0

Step 1: Checking OpenVAS (Scanner)...

通过上面输出内容，我们发现gvm组和用户有问题，并提示执行"chown -R _gvm:_gvm /var/lib/openvas/plugins"进行修复。
修复并再次检查

这次报错主要是postgresql版本的问题，下面我们按照综述中的步骤依次解决：
停止pg_clusters
# pg_lsclusters

通过上面检查结果可以看出，版本问题已解决，不再提示版本错误信息。这里的错误信息是说The Postgresql DB不存在，同时也给出了解决方法：“sudo runuser -u postgres -- /usr/share/gvm/create-postgresql-database”
启用V13版本postgresql并创建用户
# pg_createcluster 13 main
