群晖自动更新hosts
关于群晖NAS video station TMDB连接测试失败及搜刮结果下载失败的解决方案
如果使用过别的脚本或者hosts手动添加过相关的地址可以先在任务计划中执行以下脚本来清理hosts文件
#!/bin/sh
LOCAL_HOST_LIST=`cat /etc/hosts | grep -v "127.0.0.1\|::1\|^$"`
for HOST in $LOCAL_HOST_LIST; do
sed -i "/$HOST/d" /etc/hosts
done
如果hosts文件没有修改过不需要这一步
控制面板——任务计划——新增（用户自定义脚本）
填写任务名称，账户选择root
运行命令栏填写以下代码
手动执行——运行
#!/bin/sh # DOMAIN_HOST=1为启用0为关闭自定义域名hosts文件写入，GITHUB_HOST=1为启用0为关闭github域名hosts文件写入。 DOMAIN_HOST=1 GITHUB_HOST=0 # DOMAIN_LIST自定义域名列表，多域名以空格隔开，这里的域名会通过国外的DNS API返回正确的IP写入hosts文件以解决DNS污染问题。 DOMAIN_LIST=(api.themoviedb.org image.tmdb.org) GITHUB_HOST_URL="https://hosts.gitcdn.top/hosts.txt" DNS_API="https://networkcalc.com/api/dns/lookup" REMOTE_GITHUB_HOST_AT=`curl -s $GITHUB_HOST_URL | grep -w "# last fetch time:"` LOCAL_GITHUB_HOST_AT=`cat /etc/hosts | grep -w "# last fetch time:"` check_domain_host(){ for DOMAIN in ${DOMAIN_LIST[@]}; do DOMAIN_IP_LIST=`curl -k -X GET $DNS_API/$DOMAIN | jq -r '.records.A[].address'` if [ "$DOMAIN_IP_LIST" != "" ]; then for DOMAIN_IP in "$DOMAIN_IP_LIST"; do if [[ `cat /etc/hosts | grep -wc $DOMAIN_IP` = 0 ]]; then [[ `cat /etc/hosts | grep -wc "fetch-domain-hosts"` != 0 ]] && sed -i "/# fetch-domain-hosts begin/Q" /etc/hosts fi done fi done } write_domain_host(){ if [[ `cat /etc/hosts | grep -wc "fetch-domain-hosts"` = 0 ]]; then echo "# fetch-domain-hosts begin" >> /etc/hosts for DOMAIN in ${DOMAIN_LIST[@]}; do DOMAIN_IP_LIST=`curl -k -X GET $DNS_API/$DOMAIN | jq -r '.records.A[].address'` for DOMAIN_IP in $DOMAIN_IP_LIST; do echo -e "$DOMAIN_IP\t\t$DOMAIN" >> /etc/hosts done done echo "# fetch-domain-hosts end" >> /etc/hosts fi } if [ $DOMAIN_HOST = 1 ]; then check_domain_host write_domain_host else [[ `cat /etc/hosts | grep -wc "fetch-domain-hosts"` != 0 ]] && sed -i "/# fetch-domain-hosts begin/Q" /etc/hosts fi if [ $GITHUB_HOST = 1 ]; then if [ "$REMOTE_GITHUB_HOST_AT" != "" ]; then [[ `cat /etc/hosts | grep -wc "fetch-github-hosts"` = 0 ]] && curl $GITHUB_HOST_URL >> /etc/hosts if [[ "$REMOTE_GITHUB_HOST_AT" != "$LOCAL_GITHUB_HOST_AT" ]];then sed -i "/# fetch-github-hosts begin/Q" /etc/hosts && curl $GITHUB_HOST_URL >> /etc/hosts else echo "HOST无需更新" fi fi else [[ `cat /etc/hosts | grep -wc "fetch-github-hosts"` != 0 ]] && sed -i "/# fetch-github-hosts begin/Q" /etc/hosts fi |
