一、
前期回顾
书接上回， https://blog.csdn.net/alwaysbefine/article/details/160787794 Linux|操作系统|zfs文件系统的使用详解
发现在虚拟机内编译产出的rpm安装包在安装的过程中还是有一些问题，比如内核版本的需求，gcc的版本要求这些，因此，重新编译了zfs文件系统的rpm安装包，重新编译产出的zfs文件系统的rpm安装包去掉了对kernel内核版本的强校验，并基于原来的测试环境的yum源，同步制作的离线yum安装zfs文件系统的源。
经过几版的改进后，现在已基本可以做到一键在centos7系统下完全离线安装完成zfs文件系统，现对如何使用此rpm包做一个详细的介绍。

只需要用到上面标红的两个文件
二、
centos7内核升级
虽然z fs文件系统的rpm安装包 将安装时的kernel内核版本检测关闭了，但如果内核版本低于4.18，仍会不能正常工作，因此，建议内核编译安装4.18以上版本
本次实验使用的是5.4.69，推测其它版本的内核应该也是没有问题的，centos7版本是7.7.1908：
bash
[root@centos1 ~]# cat /etc/redhat-release
CentOS Linux release 7.7.1908 (Core)
[root@centos1 ~]# uname -a
Linux centos1 3.10.0-1062.el7.x86_64 #1 SMP Wed Aug 7 18:08:02 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux上面提供的zfs-2.4.1-newrpm.tar.gz这个文件解压后，就放置在root目录下，将其它的yum源移除后，配置如下离线yum源：
bash
[dsfsdaf]
name=dsfdsfsd
baseurl=file:///root/zfs-rpm
enable=1
gpgcheck=0yum源配置好后，yum makecache 缓存一下，以提高后面的使用效率
这一部分简略说一下内核升级步骤（将Linux内核源码解压后，进入该源码目录后，先移除旧的内核开发环境，然后，yum install 安装内核编译环境，生成内核编译文件，编译内核命令执行，执行完毕后设置默认内核后，重启服务器，应用新内核）：
bash
yum remove -y kernel-tools kernel-tools-libs
yum install libevent libevent-devel libtool gcc gcc-c++ systemd-devel zlib-devel libuuid-devel libblkid-devel libattr-devel libtirpc-devel openssl-devel bc ncurses-devel bison elfutils-libelf-devel flex -y#内核编译的编译环境准备
cp /boot/config-$(uname -r) .config
make -j `nproc` && make modules_install && make install#编译内核命令
# 查看新内核的菜单项，内核编译后重启服务器，设置默认内核
awk -F\' '$1=="menuentry " {print $2}' /etc/grub2.cfg | nl
# 通常新内核（5.19.11）是第 1 项（索引 0）
grub2-set-default 0
grub2-mkconfig -o /boot/grub2/grub.cfg等待服务器重启完毕后，查看Linux内核版本，确认内核升级完毕：
bash
[root@centos1 ~]# uname -a
Linux centos1 5.4.69 #1 SMP Sun May 17 20:10:49 CST 2026 x86_64 x86_64 x86_64 GNU/Linux三、
zfs文件系统的rpm安装
这个安装就非常简单了，进入zfs-rpm目录后，执行如下命令安装zfs文件系统即可：
bash
yum install zfs* -y其中部分日志如下：

Complete!此时查看zfs模块是否加载，可以看到是没有加载的，因此还需要最后一个命令
# 创建配置文件
echo zfs | tee /etc/modules-load.d/zfs.conf
该命令执行完毕后，再次重启服务器，无需手动干预，zfs模块就会自动加载好
总结：可以看到，该离线安装包完全可以独立运行，完全安装好最新版zfs文件系统，只是需要编译一个全新的Linux内核，dkms需要kernel的头文件和开发包，因此，作为依赖安装了如下软件：
bash
[root@centos1 ~]# rpm -qa |grep kernel
kernel-3.10.0-1062.el7.x86_64
kernel-ml-devel-5.19.11-1.el7.elrepo.x86_64
kernel-headers-3.10.0-1160.118.1.el7.x86_64比较重要的依赖还有python3，其它的没有什么太特别的了，我认为该离线rpm安装包是完全可以应用在生产环境的。
好了，zfs文件系统的rpm离线方式安装部署就介绍到这里，完结撒花~！！！！！！！！！！！！！！！！
