Update example_centos.rst

[alever22]

Hi, while doing a test installation on Centos 8.1 x64, I noticed that php-devel package installation failed because PowerTools repo wasn't enabled, after enabling it installation worked fine; while doing this update in document (very useful indeed, anyway) I also fixed some minor flaws

Which PHP repository are you using? When using php:remi-7.4 as indicated at https://docs.nextcloud.com/server/18/admin_manual/installation/example_centos.html php-devel seems to be available.

Hello, maybe I didn't write well, but I used the same repo as you The problem I raised was that PowerTools repository must be enabled before installing php-devel and not after, so the correct sequence is: yum install -y php-pear gcc curl-devel zlib-devel pcre-devel make (removed php-devel) yum config-manager –set-enabled PowerTools yum install -y php-devel (here it is) pecl install redis yum install -y Imagemagick ImageMagick-devel pecl install imagick If you're still in doubt, please try the original steps on a fresh clean Centos vm and you'll see that PowerTools is a requirement for php-devel Kind regards, Alessandro

Ok. Upon trying to install php-devel get a dependency error, which is satisfied when PowerTools is enabled. May want to use

 dnf install -y php-pear gcc curl-devel zlib-devel pcre-devel make

 dnf config-manager –set-enabled PowerTools

 dnf install -y php-devel php-pecl-igbinary-devel libzstd-devel

 pecl channel-update pecl.php.net

 pecl install redis

 dnf install -y ImageMagick ImageMagick-devel

 pecl install imagick

Note that there is a spelling error Imagemagick instead of ImageMagick.
igbinary enables serialization and libzstd-devel allows zstd compression. May want some information on enabling these.
You will also likely need to create systemd files for Redis and not install Redis from the repositories
since it is built by pecl.

May also want to reference documentation at:
https://redis.io/topics/quickstart
https://pecl.php.net/package/redis
https://pecl.php.net/package/imagick

To be specific without PowerTools one gets the message:

Error:
Problem: cannot install the best candidate for the job

• nothing provides libedit-devel(x86-64) needed by php-devel-7.4.5-1.el8.remi.x86_64
  (try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

PowerTools provides libedit-devel
