What about a build for FreeBSD 7 amd64 ?

mistwang · Nov 12, 2009

http://www.litespeedtech.com/packages/4.0/lsws-4.1RC2-ent-x86_64-freebsd6.tar.gz

Need to install the port for freebsd 6 compatibility.

mistwang · Nov 18, 2009

4.1RC2 packages have been updated with new feature:

H.264 video stream random seek from Flash player.

Make sure to add MIME type for mp4 video file suffix in /path/to/lsws/conf/mime.properties

to enable this feature.

Cool...
I've use this RC2 for 3 days now, and have satisfied with it

DraCoola · Nov 19, 2009

While I access WHM as domain.com/whm or xxx.xxx.xxx.xxx/whm, I've got "setuid() failed!" screen from this 4.1RC2 :

But accessing as domain.com:2086 or xxx.xxx.xxx.xxx:2086 will bring to WHM login page (normal).

Otherwise... switching to Apache bring me back both mode (for /whm and :2086) normal access to WHM.

Would you mind to check on this, george?

Thanks

mistwang · Nov 19, 2009

will take a look.

mistwang · Nov 19, 2009

We could not reproduce it in our lab.
Please strace the lscgid process with command

strace -f -p <pid_of_lscgid_process>

send us the output of strace for analysis.

DraCoola · Nov 19, 2009

Pardon me, but I cannot find the PID from lscgid as you ask me for :

Code:

root@xxx [/usr/local/lsws-4.1RC2]# pidof lscgid

root@xxx [/usr/local/lsws-4.1RC2]# pidof lshttpd
27153 27152 27151 27150 27090

mistwang · Nov 19, 2009

ps -ef | grep lscgid

DraCoola · Nov 19, 2009

Code:

root@xxx [/usr/local/lsws-4.1RC2]# ps -ef | grep lscgid
root      4499 20214  0 02:43 pts/0    00:00:00 grep lscgid
root     27094 27090  0 02:28 ?        00:00:00 httpd (lscgid)

Thank you, George.
But then... which one I should strace?

mistwang · Nov 19, 2009

27094 is it.

DraCoola · Nov 19, 2009

Here they are :

You have to produce the problem while stracing it.

too many processes running as "nobody", you need to increase "Process Soft Limit", "Process Hard Limit" accordingly.

DraCoola · Nov 19, 2009

Thank you for your suggestion. I will do that

By the way... how to make lsws showing for php process (path, file) just like php with apache did?

-----------------------------------------------------------
LSWS --> http://img98.imageshack.us/img98/2473/lsws.jpg

Apache --> http://img136.imageshack.us/img136/4618/apache.jpg

mistwang · Nov 19, 2009

It cannot show that now, we need to update the LSAPI code to do that.

DraCoola · Nov 19, 2009

What a pity...

But I hope it has already placed on your to do list

I will hopefuly wait for that LSAPI update release.
Because, sometimes, many users (especially their addon domains and subdomains) are squeezing CPU more harder than their main domain.
So the server administrator could handle (trace) that CPU-squeezer-php-files more quick and exactly right on the target.

mistwang · Nov 24, 2009

You can try the php-lsapi 5.0b2, it will show the script name being executed.
You need to build PHP manually.
