高端网站建设注意app运营需要做哪些

测试环境

openEuler-22.03-LTS-SP4-x86_64-dvd.iso
Virtual Box，4 vCPU, 8G RAM, 50 vDisk。安装时删除/home，SWAP分区，全部空间给/目录。
目标是部署OpenStack All-In-One模式，控制节点+计算节点+存储节点在一台机器实现。

系统配置

常用工具
dnf install -y tar git
优化SSH
vi /etc/ssh/sshd_config
UseDNS no
systemctl restart sshd
关闭selinux
sed -i ‘s#SELINUX=enforcing#SELINUX=permissive#g’ /etc/selinux/config
关闭防火墙
systemctl disable --now firewalld
systemctl stop firewalld
systemctl status firewalld
设置主机名，配置hosts文件
hostnamectl set-hostname node1
cat << EOF >> /etc/hosts
192.168.31.115 node1
EOF
设置免密登录
ssh-keygen
ssh-copy-id node1
重启系统
system reboot

安装docker

vi /etc/yum.repos.d/openEuler-docker-ce.repo

[docker-ce-stable]
name=Docker CE Stable - $basearchbaseurl=https://repo.huaweicloud.com/docker-ce/linux/centos/8/$basearch/stable
enabled=1
gpgcheck=1
gpgkey=https://repo.huaweicloud.com/docker-ce/linux/centos/gpg

dnf install -y docker-ce

指定docker加速器，阿里云申请免费
mkdir -p /etc/docker
tee /etc/docker/daemon.json << ‘EOF’
{
“registry-mirrors”: [“https://xxx.mirror.aliyuncs.com”]
}
EOF

systemctl daemon-reload
#启动docker服务
systemctl start docker
systemctl enable docker
systemctl status docker

docker info
docker --version
安装Python docker模块
pip3 install docker

安装ansible

更换pip国内源，加速pip下载安装
mkdir ~/.pip
vi ~/.pip/pip.conf

[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
[install]
trusted-host = pypi.tuna.tsinghua.edu.cn

pip3 install ansible
ansible --version
安装后的版本是ansible-8.7.0 + ansible [core 2.15.12]

优化ansible
mkdir /etc/ansible
vi /etc/ansible/ansible.cfg
[defaults]
host_key_checking=False
pipelining=True
forks=100

安装kolla-ansible

安装kolla-ansible需要的依赖
dnf install -y python3-devel libffi-devel gcc openssl-devel python3-libselinux

安装kolla-ansible
kolla-ansible与OpenStack之间版本信息：https://docs.openstack.org/releasenotes/kolla-ansible/
pip3 install pbr
pip3 install kolla-ansible==17.5.0
kolla-ansible --version

从Yoga版本开始需要安装Ansible Galaxy的依赖项
kolla-ansible install-deps

部署OpenStack

创建kolla-ansible配置文件目录
mkdir /etc/kolla
chown $USER:$USER /etc/kolla

配置文件
cp /usr/local/share/kolla-ansible/etc_examples/kolla/globals.yml /etc/kolla/
cp /usr/local/share/kolla-ansible/etc_examples/kolla/passwords.yml /etc/kolla/
cp /usr/local/share/kolla-ansible/ansible/inventory/all-in-one /etc/kolla/

编辑all-in-one
sed -i ‘s#localhost ansible_connection=local#node1 ansible_python_interpreter=/usr/bin/python3#g’ /etc/kolla/all-in-one

生成密码
kolla-genpwd

编辑globals.yml
cat /etc/kolla/globals.yml|grep -v ^#|grep -v ^$

workaround_ansible_issue_8743: yes
kolla_base_distro: “rocky”
openstack_release: “2023.2”
openstack_tag: “2023.2-rocky-9”
node_custom_config: “/etc/kolla/config”
kolla_internal_vip_address: “192.168.31.115”
network_interface: “enp0s3”
neutron_external_interface: “enp0s8”
enable_haproxy: “no”
enable_neutron_provider_networks: “yes”
nova_compute_virt_type: “qemu”

部署安装指定版本库，避免报错。
pip3 install pyOpenSSL==24.2.1
pip3 install cryptography==42.0.0
pip3 install paramiko==3.0.0

已安装过docker，注释掉kolla自动安装docker的任务
vi /root/.ansible/collections/ansible_collections/openstack/kolla/roles/docker/defaults/ main.yml
enable_docker_repo: false

vi /root/.ansible/collections/ansible_collections/openstack/kolla/roles/docker/tasks/main.yml
#- import_tasks: install.yml

kolla-ansible -i /etc/kolla/all-in-one bootstrap-servers
kolla-ansible -i /etc/kolla/all-in-one prechecks
kolla-ansible -i /etc/kolla/all-in-one deploy
kolla-ansible -i /etc/kolla/all-in-one post-deploy

服务验证

安装openstack客户端
dnf install -y python3-openstackclient

source /etc/kolla/admin-openrc.sh
openstack user list
openstack endpoint list
openstack project list
openstack service list
openstack volume type list
openstack network agent list
openstack compute service list
openstack volume service list
openstack hypervisor list --long

通过浏览器登录到192.168.31.115页面验证Horizon。
