gvm-21.4.3安装（kali-openvas）
一、gvm安装
为了方便先获取权限
中科大的源用不了，改用kali自己的源。进入源文件
去点kali源的注释，把中科大源注释掉。（i-修改 :wq保存修改并退出）
这个时候还不能安装，需要先更新源
安装gvm
apt-get install gvm
出现提醒
安装完成，运行设置
二、gvm初始设置
运行gvm-setup:
和上面安装中的提醒相关，是postgresql版本不匹配的问题
把13版本卸载，指定14版本为使用版本。然后再gvm-setup，运行起来了。但是显示postgresql还是有问题，后文更新安全文件到当前（可以自由活动几分钟了~）。
三、检验gvm初始设置，配置postgresql
运行完成，显示有个错误（error）
可以试着运行一下fix方案，但是没反应。
产生这个问题还是源于起初的gvm版本和postgresql版本不配套。查看相关资料发现postgresql使用的通信端口是5433，和gvm的通信端口5432对不上，因此我们选择改postgresql的端口。查看正在使用的端口。
查看进入postgresql设置文件（.conf）
修改端口号，保存退出。
修改配置之后还要重启postgresql才可以应用配置。再运行一下fix方案
成功了，然后可以检验gvm设置了
