记一次ubuntu serverDNS配置修复 安装ubuntu2004 2404并配置网卡后，DNS默认值任然为127.0.0.53# 查看dns nslookup baidu.com ;; Got SERVFAIL reply from 127.0.0.53 Server: 127.0.0.53 Address: 127.0.0.53#53 # 查看DNS文件是链接到stub-resolv.conf ls -al /etc/resolv.conf /etc/resolv.conf -> ../run/systemd/resolve/stub-resolv.conf # 查看/run/systemd/resolve/下有resolv.conf，是正确的，和网卡一致 ls /run/systemd/resolve/ # 更新为正确resolv.conf sudo mv /etc/resolv.conf /etc/resolv.conf.bak sudo ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf

CentOS 定时同步指定文件到ftp 1、安装lftpsudo yum install lftp -y2、使用命令lftp -u username,password -e "mirror -R /path/to/local /path/to/ftp; quit" ftp://ftpserver同步成功提醒Total: 1 directory, 2 files, 0 symlinks New: 2 files, 0 symlinks 5471 bytes transferred To be removed: 1 directory, 0 files, 0 symlinks可以试用crontab调用或其它方式

配置nginx端口转发 如果本地服务confluence端口为8090,每次打开都要输入端口号貌似有点不优雅。所以我们可以用nginx做本地端口转发：一、安装Nginx:Centos安装Nginx二、编辑配置文件vim /usr/local/nginx/conf/nginx.conf# confluence 8090，一个转发一个server # 将域名confluence.test.com的所有流量转发到8090端口 # 其实真实访问地址就是将“confluence.test.com” 替换成 “http://127.0.0.1:8090” server { listen 80; server_name confluence.test.com; access_log /usr/local/nginx/logs/confluence.log; location / { proxy_pass http://127.0.0.1:8090/; } } 重启服务systemctl restart nginx 三、优雅食用
