版本信息 cat /etc/*release

虚拟机linux常用NAT网络模式,通过主机访问网络。(桥接为直连路由器外网,安全不可控)

创建文件夹mkdir xzp

删除文件夹rmdir xzp

查看文件夹:ls

创建文件:touch 1.txt

查看文件:VI 1.txt     编辑模式:a或o       保存并退出:Esc→Shift+:→ wq      不保存退出:Esc→Shift+:→ q!

切换用su - root  ,su - peter

用户新增删除、权限:有流程  

运维

目标主机启动的端口:netstat -tuln (命令安装:sudo dnf install net-tools -y)
开放端口

firewall-cmd --zone=public --add-port=8888/tcp --permanent # 永久添加规则
firewall-cmd --reload # 重载配置
firewall-cmd --list-ports # 验证端口开放

验证端口开放性:nc -zv 192.168.40.168 5000(命令安装sudo dnf install nmap-ncat -y)

centos 7和8的差别:https://blog.csdn.net/seaship/article/details/109292307

系统安装:

CentOS8设置网络镜像安装源:mirrors.aliyun.com/centos/8/BaseOS/x86_64/os(https://developer.aliyun.com/article/1471190)

设置静态Ip :

CentOS7-8 有流程:vi /etc/sysconfig/network-scripts/ifcfg-ens160 重启配置:service network restart

CentOS9:https://cloud.tencent.com/developer/article/2224886

配置镜像源

centos stream 8:设置 镜像源

sudo curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo

centos stream 9设置 镜像源

编辑源配置文件:

sudo vi /etc/yum.repos.d/CentOS-Stream.repo

下载镜像源:

sudo curl -o /etc/yum.repos.d/CentOS-Stream.repo https:

替换为以下内容(覆盖原有配置):

应用:

Centos7.6 支持到.net7.6  。  .net 8910 Centos Strearm 8 才支持

1、安装 wget:yum install wget

2、配置dns服务器

echo “nameserver 8.8.8.8” | sudo tee /etc/resolv.conf

echo “nameserver 114.114.114.114” | sudo tee /etc/resolv.conf

重启dns: sudo systemctl restart NetworkManager

测试:ping mirrors.aliyun.com

3、安装.Net 8:

sudo dnf install dotnet-sdk-8.0

问题

1、服务启动报数据库连接握手协议ssl和TSL v1.0 v1.2 v1.3的问题

Unhandled exception. Microsoft.Data.SqlClient.SqlException (0x80131904): A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: TCP Provider, error: 35 - An internal exception was caught)
---> System.Security.Authentication.AuthenticationException: Authentication failed, see inner exception.
---> Interop+OpenSsl+SslException: SSL Handshake failed with OpenSSL error - SSL_ERROR_SSL.
---> Interop+Crypto+OpenSslCryptographicException: error:0A000102:SSL routines::unsupported protocol

  解决办法:配置openssl: https://cloud.tencent.com/developer/article/1816990
