My Notepad

I built my own apache 2.0.58 from source under RH EL4 using a non-root user "synew". The reasons I dont like the httpd distributed with Linux wont be dicussed here.
The self-built apache was installed in $HTTPD, using port 443 for example, then when i try to start apache using:
$HTTPD/bin/apachectl start
I got the following errors:

(13)Permission denied: make_sock: could not bind to address 163.1.26.6:443
no listening sockets available, shutting down
Unable to open logs

The reason is boz of the SELINUX distributed with RH Linux.
SOLUTION:
1)yum install selinux-policy-targeted-sources
2)vi /etc/selinux/targeted/src/policy/net_contexts
In it, you can see the port 443, 80 are set as http_port_t by default:

portcon tcp 80 system_u:object_r:http_port_t
portcon tcp 443 system_u:object_r:http_port_t

Therefore can only be used as http port by httpd daemon, not by our own built apache!! To use a port for our self-built apache, we need to as a port as http_cache_port_t, like this:

portcon tcp 3128 system_u:object_r:http_cache_port_t
portcon tcp 8080 system_u:object_r:http_cache_port_t

Add the following line to it:
portcon tcp 443 system_u:object_r:http_cache_port_t
Then remove port 443 from http_port_t list stated above.

3) make reload

***************
Don't know wether it's a bug, the above instruction is not really working. You will get an error when trying to reload it.
You can also try to disable selinux for httpd by:
setsebool -P httpd_disable_trans 1
