Homebrew has become pretty much the standard on macOS, but these days you can install Homebrew on Linux too. On Debian and RedHat you can manage packages with apt or dnf (yum), but Homebrew makes it easier to install and update programs that are not in those packages and are not published as a repository.

At some point, somewhere around when I updated the CentOS7 kernel, it stopped booting properly. When it boots, it gets stuck showing this screen and goes no further Copy Wrning: /dev/centos_web/root does not exist Warning: /dev/mapper/centos_web-root does not exist Generating "/run/initramfs/sosreport.txt" Entering emergency mode. Exit the shell to continue. Type "journalctl" to view system logs. You might want to save "/run/initramfs/sosreport.txt" to a USB stick or /boot after mounting them and attach it to a bug report. dracut:/# I figured that something grub-related had probably broken or been misconfigured when the kernel was updated, so I googled it [Read More]

zsh5.9 is the latest right now, so I have updated this article The zsh on CentOS7/8 is old, so I installed the latest version at this point, 5.9, by hand Preparation Since we use commands such as wget and make, install the developer tools first Copy $ export LANG=C $ sudo yum groupinstall "Development Tools" $ sudo yum install ncurses-devel Downloading and installing /usr/bin/zsh and /bin/zsh already exist, so install into /usr/local [Read More]

There are cases where, on a particular LDAP client machine, you want to use a different shell rather than the one defined on the LDAP server (bash) This is possible by configuring the Linux (Debian/CentOS) client to override the shell Debian11(bullseye) Add the following to /etc/libnss-ldap.conf (look up the path to the shell beforehand) Copy nss_override_attribute_value loginShell /usr/bin/zsh Flush the nscd cache Copy # nscd -i passwd nscd CentOS8 Add the following to /etc/nslcd.conf [Read More]

I posted a similar article before in GCC error with hugo on CentOS7 , but recently the build from source failed, so I worked on it.

Once again, an error caused by dependencies during a CentOS yum update The situation On CentOS7, php7.x has already been installed from the remi repository The symptom An error during yum update Copy # sudo yum update —enablerepo=remi-php73 エラー: パッケージ: php-pecl-zip-1.18.2-1.el7.remi.5.4.x86_64 (remi) 要求: php(zend-abi) = 20100525-64 インストール: php-common-7.3.0-1.el7.remi.x86_64 (@remi-php73) php(zend-abi) = 20180731-64 利用可能: php-common-5.4.16-48.el7.x86_64 (base) php(zend-abi) = 20100525-64 利用可能: php-common-5.4.45-18.el7.remi.x86_64 (remi) php(zend-abi) = 20100525-64 エラー: パッケージ: php-pecl-zip-1.18.2-1.el7.remi.5.4.x86_64 (remi) 要求: php(api) = 20100412-64 インストール: php-common-7.3.0-1.el7.remi.x86_64 (@remi-php73) php(api) = 20180731-64 利用可能: php-common-5.4.16-48.el7.x86_64 (base) php(api) = 20100412-64 利用可能: php-common-5.4.45-18.el7.remi.x86_64 (remi) php(api) = 20100412-64 問題を回避するために --skip-broken を用いることができます。 Using --skip-broken does not work either [Read More]
