由于给files.gallery开了全部权限, 防止文件泄露针对location /进行了限制访问.
server {
server_name gallery.XX.net;
index index.php;
root /home/gallery/web;
location =/ {}
location / { deny all;}
location /.well-known/acme-challenge/ { return 200; }
location ~ \.php(?:$|/) {
try_files $uri = 404;
fastcgi_pass unix:/dev/shm/php8-fpm.sock;
}
}
设定ssl证书
dnf install epel-release -y
dnf install certbot python3-certbot-nginx -y
certbot --nginx -d XXX.net --agree-tos -m [email protected]
echo "0 3 * * 6 /usr/bin/certbot renew --quiet"> /etc/cron.d/certbot
主要两个地方注意一下, cloudflare会传送一个CF-Connecting-IP的header参数为访客的真实ip,所以 read_ip读取它.
然后设定REMOTE_ADDR读取IP, 可以从FORWARDED也可以用CF-Connecting-IP参数

api.exchangerate.host 的API不能白嫖了, 找了个新的汇率接口api.vatcomply.com
原有代码
function exchange($from, $to)

$result = json_decode($result, true);
return $result['rates'][$to];

更新后

Segmentation fault

修改/etc/apt/apt.conf.d/20listchanges文件,注释掉第一行.
#DPkg::Pre-Install-Pkgs { "/usr/bin/apt-listchanges --apt || test $? -lt 10"; };
先准备一个U盘格式化为FAT32格式
将bin pkg license等文件复制到设备上
enable

智能许可： 16.9到最新的17.X所有版本
传统许可： 16.9和更低的版本
新版本用的是license smart , 以前的授权文件无法再使用, 所以要写入新签发的授权数据.
弃用10进制显示原文的community参数, 这玩意太容易忘记了.

配置ssh免密码登录
转换密钥格式
fold -b -w 72 ~/.ssh/id_rsa.pub
准备提取复制ssh-rsa到最后comment的中间一段密钥
开始配置设备
hostname Router-R1
crypto key generate rsa modulus 2048
ip ssh version 2
!
line vty 0 4
transport input ssh
login local
!
no ip ssh server authenticate user password
no ip ssh server authenticate user keyboard
!
导入密钥步骤
Router-R1(config)#ip ssh pubkey-chain
Router-R1(conf-ssh-pubkey)#username 用户名
Router-R1(conf-ssh-pubkey-user)#key-string
Router-R1(conf-ssh-pubkey-data)#粘贴密钥
Router-R1(conf-ssh-pubkey-data)#exit
Router-R1(conf-ssh-pubkey-user)#exit
Router-R1(conf-ssh-pubkey)#exit
Router-R1(config)# do wr
查看配置内容
Router-R1#show running-config | begin pubkey
ip ssh pubkey-chain
username 用户名
key-hash ssh-rsa 8FB4F858DD7E5AFB372780EC653DB371
quit
这些配置除了上新设备不常用容易忘记, 仅做备忘.
对端口进行白名单限制登录设置

先用nvme tool清理一遍磁盘
nvme list #查看所有nvme磁盘
nvme format -s1 /dev/nvme{0..11}n1 --force
wipefs清理一遍,然后mdadm建立阵列
wipefs -a /dev/nvme{0..11}n1

parted -s -a optimal /dev/nvme${i}n1 mkpart primary 0% 100%

检测下硬盘是否有阵列信息
