Upgrade Kernel 5.2

Hi there,

I use the new kernel, less memory usage better preformance.
But had to make some small adjustments to my nginx.conf

To get the nginx-bad-bot blocker to work I had to add this line

Code (Text):

limit_req_zone $binary_remote_addr zone=flood:50m rate=90r/s;

Set it to 90 because a lower setting would create some WordPress issues.

Another issue / argument is the setting

Code (Text):

sendfile on;
aio on;

I have the settig sendfile off;

Code (Text):

sendfile off;
aio on;
sendfile_max_chunk 512k;
tcp_nopush  on;

I followed the instructions here Master Branch - add NGINX_IOURING_PATCH variable support in 123.09beta01

And my custom_config.inc includes

Code (Text):

NGINX_IOURING_PATCH='y'         #  https://nginx.org/en/docs/http/ngx_http_core_module.html#aio

Going to double check it now. Strange it did not change the sendfile to the correct setting.

Noticed on a recompile that I was missing Development Tools

Code (Text):

--------------------------------------------------------
Enter option [ 1 - 24 ] 4
--------------------------------------------------------

Do you want to run YUM install checks ?  [y/n]

This will increase your upgrade duration time wise.
Check the change log centminmod.com/changelog.html
to see if any Nginx or PHP related new additions
which require checking YUM prequisites are met.
If no new additions made, you can skip the
YUM install check to speed up upgrade time.

 [y/n]: y
*************************************************
* Installing Development Tools
*************************************************
please wait for yum download and installs to complete.
yum installs in less verbose mode so final install status is only shown..

I normally don't press Y, but wanted to be sure I did not miss anything, new server so just checking.

Edit>
Continueof recompile.... It hangs

executed in other open shell

Code (Text):

kill -USR2 18636

And it continues again.
But soon after that next issue

Code (Text):

checking... worker child PPID=18636 exists
 checking... worker child PPID=18636 exists
 checking... worker child PPID=18636 exists
 checking... worker child PPID=18636 exists
 checking... worker child PPID=18636 exists
 checking... worker child PPID=18636 exists
 checking... worker child PPID=18636 exists
 checking... worker child PPID=18636 exists

Again in onther open shell

Code (Text):

kill -9 18636

And nginx recompile is ready

Check nginx.conf file...

Code (Text):

sendfile off;
aio on;
sendfile_max_chunk 512k;
tcp_nopush  on;

No changes, so manual changed sendfile on;

Strange, want to trouble shoot it.

 

cminfo would have given the previous beta, I posted this a while ago.
