关于apache 路径转发的一些问题

one fine day we were unabe to access app1 and app2 using proxy, when we checked logs we found following error in error_log (/etc/httpd/logs/error_log)

[error] (13)Permission denied: proxy: HTTP: attempt to connect to 127.0.0.1:8080 (127.0.0.1) failed
[error] ap_proxy_connect_backend disabling worker for (127.0.0.1)

Solution: Run following command

# /usr/sbin/setsebool httpd_can_network_connect 1
OR
# /usr/sbin/setsebool httpd_can_network_connect true
Or you can also set the security settings, Go to Security Level configurations and Change Tab to SELinux. And modify SELinux policy Check “Allow HTTPD scripts and modules to connect to the network” under HTTPD service.

You can add ‘-P’ if you want this change to persist over system restarts, eg:

/usr/sbin/setsebool -P httpd_can_network_connect 1

2.centos 6.2 转发的文件跟 ubuntu win7 都不一样
