Fedora跨版本升级
最近今天心血来潮又折腾了下fedora, 直接从23跳到34版本.
但是遇上了rpmlib(PayloadIsZstd) <= 5.4.18-1 is needed by 错误.
大致上就是rpmlib依赖包过不去又不想挨个版本升级,
简单搜索了下解决方案先升级到25 30 32 然后就可以升级至34最新了.
dnf system-upgrade download --releasever=34 --allowerasing --nogpgcheck -y
dnf system-upgrade reboot
顺道看了下fedora自带php7.4 / mariadb 10.5 / nginx 1.20 也有openresty的支持, 其实用于个人的生产环境妥妥的简单省事.
windows终于有个像样的终端了 - Windows Terminal
现在windows10下的PowerShell下命令安装， 或者直接在商店里面搜索Windows Terminal并安装。
winget install --id=Microsoft.WindowsTerminal -e大致上看了一下可以支持各种配色，除了windows拉跨的字体渲染显示比较拉跨外，其他都还不错。
搭配一下OpenSSH再配置下RSYNC基本上用起来和Linux原生环境差不多了。
安装完后在cmd或者powershell里面运行wt就启动了， 接下来配色更换字体等等都可以DIY定制了。
怀旧系列:重玩Xen
自从Kvm进入内核自带后自己编译Xen内核相对比较麻烦, 已经很多年没玩Xen了.
Centos也停止Xen更新了, 另外还有个crc.id.au的一直在更新维护安装包.
https://xen.crc.id.au/downloads/
https://wiki.centos.org/HowTos/Xen/Xen4QuickStart
由于有现成的安装包, 就不用去编译内核了.
Centos的remi repo配置引导
https://rpms.remirepo.net/wizard/
yum -y install epel-release -y
yum install https://rpms.remirepo.net/enterprise/remi-release-8.rpm
备用记录下, 下次装libzip不用去编译了.
yum -y --enablerepo=remi install libzip-last-devel
none
Centos8编译安装php8
yum -y install epel-release
