看见 hostloc 上有人求黑群怎么自动更新 ssl 证书

没有 hostloc 帐号，所以不能回复，贴上自己写的自动更新 ssl 证书脚本，以便帮助有需要的人。 ps：

1. 这个脚本工作于我的 dsm6.2 ，如果是 dsm7 ，你可能需要更改下证书存放路径和服务重启方式（自己找找相关信息，思路是一样的）
2. 由于运营商封 80 端口，所以不能使用 http challenge ，只能使用 dns challeng 。这个脚本使用的是 acme.sh 的 cloudflare 的 api ，如果要改成其它提供商如阿里云，请参考 acme.sh 相关文档，切换应该也很简单

#!/bin/bash # Automatically update certs for Synology DSM6 # 1. Migrate your domain to Cloudflare, and create an A type record. # 2. Generate a token with zone view authority and dns edit authority. # 3. Install acme.sh on DSM6, no need crontabs: ./acme.sh --install --force -m [email protected] # 4. Put this script into user defined task scheduler, executes per one month or two. # 5. Make sure this script will be exectuted once immediately by your schedule task, or just execute it once mannually. # Modify these as your own. # See https://github.com/acmesh-official/acme.sh/wiki/dnsapi#using-the-new-cloudflare-api-token-you-will-get-this-after-normal-login-and--scroll-down-on-dashboard-and-copy-credentials export CF_Account_ID="xxx" export CF_Zone_ID="xxx" export CF_Token="xxx" DOMAIN_RECORD='example.com' ACME_HOME=$HOME/.acme.sh ACME_SH=$ACME_HOME/acme.sh if ! command -v "$ACME_SH" &>/dev/null; then echo "Please install acme.sh." exit 1 fi DOMAIN_CERT_HOME="$ACME_HOME/$DOMAIN_RECORD" TARGET_DIRS=( "/usr/syno/etc/certificate/_archive/$(head -n1 /usr/syno/etc/certificate/_archive/DEFAULT | xargs echo -n)" '/usr/syno/etc/certificate/system/default' '/usr/syno/etc/certificate/smbftpd/ftpd' '/usr/local/etc/certificate/CardDAVServer/carddav' '/usr/local/etc/certificate/SynologyDrive/SynologyDrive' '/usr/local/etc/certificate/WebDAVServer/webdav' ) issue_or_renew() { cert_issued=0 domains=() while IFS='' read -r line; do domains+=("$line"); done < <($ACME_SH --list | awk '{print $1}') for domain in "${domains[@]}"; do if [ "$domain" = "$DOMAIN_RECORD" ]; then cert_issued=1 break fi done if [ "$cert_issued" -eq 0 ]; then rm -rf "$DOMAIN_CERT_HOME" # Issue certs via zerossl, or via letsencrypt you'd have to update ca-certificates on DSM6. # Since DSM6 does not support ecc, rsa(-k) should be specified, or system default certs will be overridden by DSM6 when reboots. $ACME_SH --issue --server zerossl --dns dns_cf -d $DOMAIN_RECORD -k 2048 else $ACME_SH --renew --force -d $DOMAIN_RECORD fi } copy_certs() { echo "Copying certs...." for dir in "${TARGET_DIRS[@]}"; do install -m 400 "$DOMAIN_CERT_HOME/$DOMAIN_RECORD.cer" "$dir/cert.pem" install -m 400 "$DOMAIN_CERT_HOME/$DOMAIN_RECORD.key" "$dir/privkey.pem" install -m 400 "$DOMAIN_CERT_HOME/fullchain.cer" "$dir/fullchain.pem" done echo "Certs copy completed." } restart_services() { echo "Restarting services...." nginx -s reload /var/packages/WebDAVServer/scripts/start-stop-status stop /var/packages/CardDAVServer/scripts/start-stop-status stop sleep 20 /var/packages/WebDAVServer/scripts/start-stop-status start /var/packages/CardDAVServer/scripts/start-stop-status start /var/packages/SynologyDrive/scripts/start-stop-status restart echo "Services restart completed." } echo '--------------------------------------' issue_or_renew copy_certs restart_services
