使用Let's Encrypt签发的免费https证书
发布时间:February 2, 2018 // 分类: // No Comments
安装ssl证书获取工具certbot,安装前先删除request及urllib包,不然可以会出现No module named 'requests.packages.urllib3' 的错误:
pip uninstall requests -y
pip uninstall urllib3 -y
yum remove python-urllib3 -y
yum remove python-requests -y
yum install python-urllib3 -y
yum install python-requests -y
yum install certbot -y
centos8直接下载certbot,运行时会自动安装依赖:
wget https://dl.eff.org/certbot-auto
获取证书,成功后证书文件在 /etc/letsencrypt/live/haiyun.me/目录下
certbot certonly --webroot --email sss@haiyun.me --agree-tos --no-eff-email -w /var/www/www.haiyun.me -d haiyun.me -d www.haiyun.me
配置nginx:
listen 443 default ssl ;
server_name www.haiyun.me haiyun.me;
index index.html index.htm index.php;
root /var/www/www.haiyun.me;
ssl_certificate /etc/letsencrypt/live/haiyun.me/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/haiyun.me/privkey.pem;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers HIGH:!aNULL:!MD5;
ssl_prefer_server_ciphers on;
由于Let's Encrypt的免费证书有效期为3个月,60天可以更新,使用cron定时任务自动更新证书:
00 01 * * * certbot renew --renew-hook "nginx -s reload"
吊销证书:
certbot revoke --cert-path /etc/letsencrypt/live/haiyun.me/cert.pem --key-path /etc/letsencrypt/live/haiyun.me/privkey.pem
迁移服务器备份:
cd /etc/letsencrypt
tar zcf letsencrypt.tar.gz archive live renewal
ipip的besttrace路由跟踪工具
发布时间:February 2, 2018 // 分类: // No Comments
跟踪路由时显示IP运营商、ASN及所在位置:
yum install unzip wget -y
wget https://cdn.ipip.net/17mon/besttrace4linux.zip
unzip -d /usr/local/bin/ besttrace4linux.zip "besttrace"
chmod +x /usr/local/bin/besttrace
#如需非root运行
setcap cap_net_raw=+eip /usr/local/bin/besttrace
alias 'besttrace=besttrace -q 1'
echo "alias 'besttrace=besttrace -q 1'" >> /root/.bashrc

KVM VPS dd安装自定义系统镜像
发布时间:January 20, 2018 // 分类: // No Comments
制作kvm dd系统见:https://www.haiyun.me/archives/1175.html
使用Debian网络安装包启动引导系统进入shell并dd恢复镜像到硬盘:
wget -O initrd.gz ftp://ftp.cz.debian.org/debian/dists/stable/main/installer-amd64/current/images/netboot/debian-installer/amd64/initrd.gz
wget -O linux ftp://ftp.cz.debian.org/debian/dists/stable/main/installer-amd64/current/images/netboot/debian-installer/amd64/linux
wget -O firmware.cpio.gz http://cdimage.debian.org/cdimage/unofficial/non-free/firmware/stable/current/firmware.cpio.gz
cp -p initrd.gz initrd.gz.orig
cat initrd.gz.orig firmware.cpio.gz > initrd.gz
rm -rf firmware.cpio.gz initrd.gz.orig
mv initrd.gz linux /boot/
编辑grub配置文件添加启动项:
menuentry "Debian Boot" {
set root=(hd0,msdos1)
linux /boot/linux boot=casper initrd=initrd.gz noprompt textonly --
initrd /boot/initrd.gz
}
记录ip子网信息,重启系统通过vcn选择从debian启动,在debian安装界面选择go back,然后可以选择configure network配置网络(可dhcp),或直接进入execute a shell手动配置ip信息:
ip addr add 45.63.13.2/255.255.254.0 dev ens3
ip link set ens3 up
ip rou default dev ens3
开始dd:
wget -qO- http://47.74.1.1/winxp.img.gz |gunzip -dc |dd of=/dev/vda && reboot
