Problem getting Php PDO support working

hkirsman — Sat, 31 Mar 2018 10:02:00 +0000

Forums:

I've tried installing php7-fpm + nginx + mysql. Almost seems done but for some reason I'm still getting PHP Fatal error: Class 'PDO' not found. I've installed all kinds of different pdo related packages listed here https://pkgs.alpinelinux.org/packages?name=*pdo*&branch=edge&repo=community but when I check phpinfo() then I don't see PDO as enabled. Any hints where to check? Google seems to ignore my requests regarding apk-alpine-pdo-not-found-etc queries

I've used Standard Alpine distro for installation.

What is “modloop” option in Alpine?

I'm trying to understand what is the difference of making Alpine installation medium as read-only type (LiveCD) and as a standard disk mode (where the OS state can be saved). I've seen the modloop option when the author of this article (https://wiki.alpinelinux.org/wiki/Create_UEFI_boot_USB) configured loader entries for UEFI boot mode:

Contents of loader/entries/alpine.conf
title    Alpine Linux
linux    /boot/vmlinuz-hardened
initrd   /boot/initramfs-hardened
options  modloop=/boot/modloop-hardened modules=loop,squashfs,sd-mod,usb-storage quiet

And the question is how options listed in this stanza modloop=/boot/modloop-hardened modules=loop,squashfs,sd-mod relate to each other and what do they mean?

Alpine LVM installation with UEFI/Legacy BIOS booting support

Hi folks! :)
I'm very new to Alpine and want somebody help me to check if the steps I've done are correct with regards to my intention.
I want to move from Arch+Windows [GPT, dual boot using built-in EFI menu] to Alpine+Windows [GPT, legacy BIOS booting support, XEN, LVM partitions for both Alpine as Dom0 and virtualized Windows as Dom1]. Let's say it is my "research" idea :). How to make an instance of Windows in XEN and how to install it is out of the scope. I will do it on my own. I'm concerning more about booting process: propertly configured flags & options, syslinux.conf, included features & modules into initramfs, etc. The installation will be made using external HDD. There are two reasons for this: (1) to be sure everything works ok before moving to built-in one and (2) to make the solution portable/Live. **Please, no GRUB**. Want to make it done using SYSLINUX only.

So, here is how I "imagine" the disk layout should be:

[mbrgpt.bin] # see [3]
[protective MBR]
[GPT table]
EFI partition (FAT32, 200MB) # mount point is /mnt/EFI, see [1]
LVM partition
    /boot (FAT32, 200MB)  # mount point is /mnt/LVM/boot, see [2]
    / (EXT4, 40GB)        # mount point is /mnt/LVM/root
    windows (NTFS, 60GB)
   ...

This is my assumption list:

[1] I need to copy /usr/share/syslinux/efi64/syslinux.efi as /mnt/EFI/EFI/Boot/bootx64.efi and create /mnt/EFI/loader/entries/alpine.conf. Content of the latter should coincide with syslinux.cfg. For reference I use: https://wiki.alpinelinux.org/wiki/Create_UEFI_boot_USB#Create_configuration_files_for_boot_loader
[2] I know it's not a good idea to make /boot part of LVM structure but for research purposes - want it to be a logical volume anyway (or do not create it at all). I heard at Arch Linux forum that SYSLINUX does support it. However, didn't find any "witnesses" on the web.
[3] If I boot from legacy BIOS system, gptmbr.bin should somehow to find and jump over to /mnt/LVM/boot/syslinux/ldsyslinux.c32. Then load syslinux.cfg and determine how XEN kernel should be started.
If I boot from UEFI system, syslinux.efi starts and options taken from loader/entries/alpine.conf (certainly, content should coincide with syslinux.cfg).

There is some uncertainty about the things I didn't find much information on the web:

Difference between Syslinux's ldlinux.sys and ldlinux.c32. There is some information on Arch's wiki which says sys is loader and loads rest of itself from c32. Nothing more..
Difference between Syslinux's mbr.bin and gptmbr.bin boot records. Seems like the second one is what I need but don't know why.

This is my "TODO" list (things like mkdir & umount were skiped for short). Please note, steps marked with (?) need for additional clarification:

1. Partitioning medium
gdisk /dev/sdx
# create new GPT table
# create EFI partition and set type to "EFI System" (sdx1)
# create Linux LVM part and set type to "Linux LVM" (sdx2)
# set an attribute for EFI part (?)
# known attributes are:
0: system partition
1: hide from EFI
2: legacy BIOS bootable (seems like this is what gptmbr.bin need to pick it up)
60: read-only
62: hidden
63: do not automount
 
2. Format EFI partition 
apk add dosfstools
mkfs.fat -F 32 /dev/sdx1
 
3. Copy SYSLINUX's UEFI bootloader
mount /dev/sdx1 /mnt/EFI
cp /usr/share/syslinux/efi64/syslinux.efi /mnt/EFI/EFI/Boot/bootx64.efi
 
4. Install LVM
apk add lvm2
rc-update add lvm
# add device mapper
modprobe dm-mod
echo dm-mod >> /etc/modules
 
5. Create LVM layout
pvcreate /dev/sdx2
vgcreate vg0 /dev/sdX2
# root
lvcreate -n root -L 40G vg0
mkfs.ext4 /dev/vg0/root
# boot
lvcreate -n boot -L 200M vg0
mkfs.fat -F 32 /dev/vg0/boot
# windows etc goes here ...
 
6. Rebuild initramfs
mount /dev/vg0/root /mnt/LVM/root
vi /etc/mkinitfs/mkinitfs.conf # append lvm to features=".."
mkinitfs -c /etc/mkinitfs/mkinitfs.conf -b /mnt/LVM/boot
 
7. Create swap file
mount /dev/vg0/root /mnt/LVM/root && cd /mnt/LVM/root
fallocate -l 2G ./swapfile
# or dd if=/dev/zero of=./swapfile bs=1M count=2048
chmod 600 ./swapfile
mkswap ./swapfile
swapon ./swapfile
rc-update add swap
# add '/swapfile none swap defaults 0 0' to /etc/fstab
 
8. Install SYSLINUX package & burn VBR
apk add syslinux
dd if=/usr/share/syslinux/gptmbr.bin of=/dev/sdx
 
9. Copy Alpine
mount /dev/vg0/boot /mnt/LVM/boot
setup-bootable /path/to/latest-alpine.iso /mnt/LVM/boot
 
10. Install SYSLINUX and tight things together
syslinux --directory /boot/syslinux/ --install /dev/sdb1
vi /mnt/LVM/boot/syslinux/syslinux.cfg # (?)
vi /mnt/EFI/loader/entries/alpine.conf # (?)
 
Last. Store changes made locally into root
lbu package - | tar -C /mnt/LVM/root -xzf -

Questions:

Are the steps above a good way to go? If I missed something or overcomplicated, please let me know.
Do I need to mark /dev/vg0/boot somehow in order gptmbr.bin could find the partition when it boots?
Can I get rid of LVM boot partition and substitute /mnt/LVM/boot with /mnt/LVM/root where I mentioned it?

Failure to boot/install on Raspberry Pi Zero W

Installation

Hi folks. I'm trying to install Alpine on a Raspberry Pi Zero W. I created an SD card as per the wiki instructions. However, the device appears to never load the kernel. It simply powers itself off after a moment or two. I can, however, use the same SD card to boot Retro Pie with the device. So I'm pretty sure things should work. Can anybody tell me what would cause it to just shut the hardware down instead of say, hanging with a kernel panic or something?

I tried removing "quiet" from the command line, but it doesn't get far enough to even show any text on the screen.

Thanks!

apk behind corporate proxy which has a self signed certificate

General discussion

Hello all,

for some time now i have been trying to get apk to work in a Dockerfile, using a corporate proxy which has a self signed certificate.

i tried to import the CA, Intermediate and the cert in pem format to /etc/ssl/certs, /etc/ssl but i always get

139718424861644:error:14007086:SSL routines:CONNECT_CR_CERT:certificate verify failed:ssl_clnt.c:1026:

The setup is roughly as follows (its a Django app) :

Dockerfile:

FROM python:3.7-rc-alpine
...
ENV APK_OPTS --no-cache --repository 'https://bla/latest-stable/main'
...
ADD $APP_CERT_DIR /etc/ssl/certs/
...
RUN apk add $APK_OPTS musl gcc libxml2-dev libxslt-dev musl-dev libxml2 libxslt

any clues would be greatly appreciated ;)

Thanks!

will either ARM version run on the pi?

will either ARM version run on the pi? or just the pi version? the debian page say armhf requires armv7 and newer and the pi zero is an arm11 cpu?

i suppose i'm just splitting hairs the zero is anemic getting anything to run on it should be good enough.

clang++: 'iostream' file not found

How do I configure my Alpine box so that clang++ can find the traditional "iostream" header?

For now, I'll just use g++, but it would be cooler to have the fuller static analysis capabilities of clang++ for improving my C/C++ code.

ca-certificates (missing) for alpine-virt-3.7.0-x86_64.iso

Installation

Hello,

I'm trying to setup a Vagrant box as an Alpine guest virtual machine, but when I go to install ca-certificates with apk add -U ca-certificates, apk complains that it can't find ca-certificates. What's more, apk is able to install openssh, so that would seem to rule out a DNS issue.

Source:

https://github.com/mcandre/packer-templates/blob/alpine/alpine/fix-vagrant-ssh.alpine.sh

Update:

I had neglected to run setup-alpine, so the /etc/apk/repositories file was pointing merely at the ISO disc for packages, which omits the ca-certificates package.
