用lighttpd解决了，但是自带的lighttpd无mod_openssl.so错误。
2019-05-05 14:02:59: (configfile.c.60) Warning: please add “mod_openssl” to server.modules list in lighttpd.conf. A future release of lighttpd 1.4.x will not automatically load mod_openssl and lighttpd will not use SSL/TLS where your lighttpd.conf contains ssl.* directives
2019-05-05 14:02:59: (plugin.c.229) dlopen() failed for: /usr/lib/lighttpd/mod_openssl.so Error loading shared library /usr/lib/lighttpd/mod_openssl.so: No such file or directory
2019-05-05 14:02:59: (server.c.1141) loading plugins finally failed
我安装openwrt官方源重新安装就正常了。
希望下次固件更新的时候解决一下。
