vhosts.conf
<VirtualHost *:8080> ServerAdmin webmaster@dummy-host.example.com ServerName j.ptl.com ProxyRequests Off <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPass / http://127.0.0.1:81/ ProxyPassReverse / http://127.0.0.1:81/ </VirtualHost>
然后 httpd.conf 里面取消注释以下两行
#LoadModule proxy_module modules/mod_proxy.so
#LoadModule proxy_http_module modules/mod_proxy_http.so
重启后应该正常
