Linux – Upgrade from Freetype / Compile PHP GD extension

Amazon Linux 2 for Elastic Beanstalk PHP includes Freetype 2.3.11, which does not properly render the fonts for my project. So I downloaded Freetype 2.10.1 and created / without / with Harfbuzz according to Then I compiled the PHP GD extension as follows.

cd php-7.2.19/ext/gd
./configure --with-php-config=/usr/bin/php-config --with-gd --with-freetype-dir=/usr --with-png-dir=/usr --with-xpm-dir=/usr --with-webp-dir=/usr
sudo cp modules/ /usr/lib64/php/7.2/modules/

Linux error: -bash syntax error near the unexpected token & # 39; KERN_INFO "

I just started my CSC 2260 class last week. We use Virtual Box to work with Linux, and for this task we learn about kernels. I could add, load and unload. However, I have a problem when it comes to finding the golden ratio with the code given by the professor. She asks us to get the value with printk (KERN_INFO "% lu n", GOLDEN_RATIO_PRIME). But when I do that, I get a bash syntax error about unexpected tokens. I am new to this type of coding and have wondered if anyone knows what I did wrong.

Linux subdomain virtualmin does not work

Hello and thank you for your time.

I have a domain that works very well on Linux Server with Virtualmin,

Within Domain that I created as a "subdomain" but does not work online and will be displayed as a missed page. These are my global settings for my subdomain in Virtualmin:

What else can I do to fix the problem?

Networking – How do I set Rx Queue = N on Linux / in Qemu / KVM?

I've configured 8 multiple queues on my CentOS VM box (running on KVM).


I can find that 8 queues are created on VM with Ethtool.

(centos@vm ~)$ ethtool -l eth1
Channel parameters for eth1:
Pre-set maximums:
RX:     0
TX:     0
Other:      0
Combined:   8
Current hardware settings:
RX:     0
TX:     0
Other:      0
Combined:   4

Now I wanted to restrict 1 RX queue and 2 TX queues for my DPDK application. I am trying to set the same with ethtool, but the following error is issued:

(centos@vm ~)$ sudo ethtool -L eth1 rx 1 tx 2
Cannot set device channel parameters: Invalid argument

I can set combined queues = 2, but not specific RX / TX queues.

(centos@vm ~)$ sudo ethtool -L eth1 combined 2
(centos@vm ~)$ ethtool -l eth1
Channel parameters for eth1:
Pre-set maximums:
RX:     0
TX:     0
Other:      0
Combined:   8
Current hardware settings:
RX:     0
TX:     0
Other:      0
Combined:   2

Any reason / rationale?

Is there another way I can set up RX and TX queues on Linux?

Can I specify the size of the RX and TX queues in the libvirt XML / Qemu command? I googled it before I asked that question but could not find anything.

Many thanks.

Linux ps have different columns with process ID

I have the simple Docker command to stop the database process:

docker exec  app-pgsql bash -c 'ps axuf |grep ils |cut -d" " -f3 |xargs kill -9 || :'

and as you see, I search the 3rd column ps to get process ID, but sometimes this column is different, once 3rd, second time 4th, next time 3rd etc.
Is there a better solution to fix this, no matter which column will be?

Linux Network – To forward traffic from a specific Apache2 domain to the LXC container

I'm running Apache2 on my server, but I want to forward HTTP traffic requesting a specific host (for example, to an LXC container that has a local IP address on the server Box can be accessed.

I've been working on iptables, but I understand that iptables does not handle http (s) traffic. As far as I can tell, there are no redirect rules based on the hostname that I can apply.

I would prefer not to forward the traffic to a specific port (for example, because it makes the URL look unprofessional and requires additional port forwarding configuration.

It seems like there is probably an obvious solution that I miss, but my search has not revealed anything yet. Any help would be appreciated.
