之前使用过 HAProxy 配置过一次，略显繁琐，现在带来了更加便捷的方法。 利用 OpenWrt 自带的 uhttpd 服务，暴露一个接口。 在 `/www/cgi-bin/` 目录下新增一个文件，例如 `healthcheck`，内容如下： ```bash #!/bin/sh uclient-fetch --timeout=5 --no-check-certificate -O - https://www.gstatic.com/generate_204 >/dev/null 2>&1 if [ $? -eq 0 ]; then echo "Status: 200 OK" echo "Content-Type: text/plain" echo "" echo "Network OK" else echo "Status: 503 Service Unavailable" echo "Content-Type: text/plain" echo "" echo "Network Failed" fi ``` 设置文件权限。 ```bash chmod a+x healthcheck ``` 新增一个 uhttpd 实例，监听在 8081 端口，并且默认访问 `/` 时定向到 `/cgi-bin/healthcheck`。 ```bash uci set uhttpd.healthcheck=uhttpd uci add_list uhttpd.healthcheck.listen_http='0.0.0.0:8081' uci add_list uhttpd.healthcheck.listen_http='[::]:8081' uci set uhttpd.healthcheck.redirect_https='0' uci set uhttpd.healthcheck.rfc1918_filter='1' uci set uhttpd.healthcheck.home='/www' uci set uhttpd.healthcheck.tcp_keepalive='1' uci add_list uhttpd.healthcheck.alias='/=/cgi-bin/healthcheck' uci set uhttpd.healthcheck.cgi_prefix='/cgi-bin' uci set uhttpd.healthcheck.script_timeout='60' uci set uhttpd.healthcheck.network_timeout='30' uci set uhttpd.healthcheck.http_keepalive='20' uci set uhttpd.healthcheck.max_connections='100' uci set uhttpd.healthcheck.max_requests='3' uci commit uhttpd /etc/init.d/uhttpd restart ``` 在 RouterOS 上新建一个监控服务。 ```shell add comment="passwall healthcheck" name=passwall_healthcheck \ up-script=enable_passwall down-script=disable_passwall \ type=http-get interval=15s timeout=5s \ host=192.168.88.2 port=8081 ``` Loading... 之前使用过 HAProxy 配置过一次，略显繁琐，现在带来了更加便捷的方法。 利用 OpenWrt 自带的 uhttpd 服务，暴露一个接口。 在 `/www/cgi-bin/` 目录下新增一个文件，例如 `healthcheck`，内容如下： ```bash #!/bin/sh uclient-fetch --timeout=5 --no-check-certificate -O - https://www.gstatic.com/generate_204 >/dev/null 2>&1 if [ $? -eq 0 ]; then echo "Status: 200 OK" echo "Content-Type: text/plain" echo "" echo "Network OK" else echo "Status: 503 Service Unavailable" echo "Content-Type: text/plain" echo "" echo "Network Failed" fi ``` 设置文件权限。 ```bash chmod a+x healthcheck ``` 新增一个 uhttpd 实例，监听在 8081 端口，并且默认访问 `/` 时定向到 `/cgi-bin/healthcheck`。 ```bash uci set uhttpd.healthcheck=uhttpd uci add_list uhttpd.healthcheck.listen_http='0.0.0.0:8081' uci add_list uhttpd.healthcheck.listen_http='[::]:8081' uci set uhttpd.healthcheck.redirect_https='0' uci set uhttpd.healthcheck.rfc1918_filter='1' uci set uhttpd.healthcheck.home='/www' uci set uhttpd.healthcheck.tcp_keepalive='1' uci add_list uhttpd.healthcheck.alias='/=/cgi-bin/healthcheck' uci set uhttpd.healthcheck.cgi_prefix='/cgi-bin' uci set uhttpd.healthcheck.script_timeout='60' uci set uhttpd.healthcheck.network_timeout='30' uci set uhttpd.healthcheck.http_keepalive='20' uci set uhttpd.healthcheck.max_connections='100' uci set uhttpd.healthcheck.max_requests='3' uci commit uhttpd /etc/init.d/uhttpd restart ``` 在 RouterOS 上新建一个监控服务。 ```shell add comment="passwall healthcheck" name=passwall_healthcheck \ up-script=enable_passwall down-script=disable_passwall \ type=http-get interval=15s timeout=5s \ host=192.168.88.2 port=8081 ``` 最后修改：2026 年 01 月 09 日 © 允许规范转载 打赏 赞赏作者 支付宝微信 赞 如果觉得我的文章对你有用，请随意赞赏
