第一章 openEuler22.03制作openstack平台使用的镜像

---

---

前言

使用openEuler22.03的iso制作openstack平台使用的云主机镜像。
使用的镜像：openEuler-22.03-LTS-SP1-x86_64-dvd.iso
使用的工具：virt-manager

---

一、virt-manager上的准备工作

首先将网卡类型，硬盘类型修改为Virtio类型

1、网卡类型切换为virtio

2、IDE驱动设置成Virtio

3、Display设置成vnc

3、虚拟机系统分区

只保留一个跟目录分区即可

---

二、安装普通工具包

yum install -y vim-enhanced wget unzip zip tree tar sysstat iftop htop
yum install -y net-tools pciutils traceroute wget unzip zip psmisc bash-completion 
yum install -y tcpdump yum-utils epel-release tar

---

三、安装云化工具包

1、安装工具包

yum install -y qemu-guest-agent cloud-init cloud-utils cloud-utils-growpart gdisk

2、修改配置文件

#默认是true，修改成false，打开root账户
disable_root: false
#默认是0，修改成1，打开密码登陆
ssh_pwauth:   1

system_info:
   default_user:
     #将openeuler修改成root
     name: root
     #默认是true，修改成false，放开管理员密码登陆
     lock_passwd: false
     增加下一行
     sudo: ["ALL=(ALL) NOPASSWD:ALL"]

3、服务状态设置

systemctl status cloud-init-local
systemctl status cloud-init
systemctl status cloud-config
systemctl status cloud-final

systemctl enable cloud-init-local
systemctl enable cloud-init
systemctl enable cloud-config
systemctl enable cloud-final

systemctl start cloud-init-local
systemctl start cloud-init
systemctl start cloud-config
systemctl start cloud-final

---

四、其他配置

1、关闭防火墙和selinux

#关闭selinux
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/sysconfig/selinux
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

#关闭防火墙
systemctl restart firewalld.service
systemctl disable firewalld.service

2、设定欢迎词

echo 'Welcome to openstack Cloud Elastic Compute Service !' >> /etc/motd;

3、SSHD服务配置

sed -i 's/GSSAPICleanupCredentials/#GSSAPICleanupCredentials/g' /etc/ssh/sshd_config;
sed -i 's/GSSAPIAuthentication/#GSSAPIAuthentication/g' /etc/ssh/sshd_config;
echo '#openstack-ssh-properties' >> /etc/ssh/sshd_config;
echo 'UseDNS no' >> /etc/ssh/sshd_config;
echo 'GSSAPICleanupCredentials no' >> /etc/ssh/sshd_config;
echo 'GSSAPIAuthentication no' >> /etc/ssh/sshd_config;

五、清理历史记录

rm -rf /var/log/*.0
rm -rf /var/log/*.1
rm -rf /var/log/*.2
rm -rf /var/log/*.3
rm -rf /var/log/*/*.0
rm -rf /var/log/*/*.1
rm -rf /var/log/*/*.2
rm -rf /var/log/*/*.3
for x in `find /var/log/ -name "*.log.*"`; do rm $x; done
for y in `find /var/log/ -name "*.gz"`; do rm $y; done
for z in `find /var/log/  -type f`; do cat /dev/null >$z; done
history -c && history -w

#执行下面命令，清理用户登录记录。
echo > /var/log/wtmp

echo > /var/log/btmp

#执行下面命令清除历史操作记录。
history -w;echo > /root/.bash_history;history -c;history -c;history -c;

总结

总体上制作方式一致，直接使用云计算的版本有点不好使，就自己做一版了
