本部说明如何在离线环境下如何安装 Nginx Plus 及 Nginx Controller

安装介质准备

安装介质需要提前准备，介质的下载需要在可连接互联网的环境上进行，具体安装介质包括：

编号名称类型说明

1

Docker

rpm

Docker Community Edition (CE) 18.09

2

Kubernets RPM

rpm

安装 Kubernets 所需 RPM 包（kubeadm、kubelet、kubectl）

3

Kubernets Docker Image

tar

安装 Kubernets 所需要的 docker 镜像

4

Nginx controller

tar

需要 License，可到链接申请试用

5

Nginx+

rpm

需要 License，可到链接申请试用

6

PostgreSQL

rpm

安装 Nginx controller 所需的数据库

7

Other

rpm

离线环境中包拷贝，源初始化所需

创建如下三个目录，分别保存 rpm, docker image, other
mkdir {rpm,tar,db,other}
mkdir rpm/{docker,kubernets}
mkdir other/{wget,vim,tree,jq,postgre}

Docker

本部分下载 Docker Community Edition (CE) 18.09 到本地。

1. yum 源配置
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
2. 下载 rpm 包到本地
yum install --downloadonly --downloaddir=rpm/docker/ docker-ce-18.09.9-3.el7

Kubernets RPM

1. 配置 yum 源
cat <<EOF > /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://packages.cloud.google.com/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://packages.cloud.google.com/yum/doc/yum-key.gpg https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg
EOF
2. 下载 rpm 包到本地
KUBE_VERSION=1.15.5
for i in kubeadm-${KUBE_VERSION}-0.x86_64 kubelet-${KUBE_VERSION}-0.x86_64 kubectl-${KUBE_VERSION}-0.x86_64 ; do yum install --downloadonly --downloaddir=rpm/kubernets $i ; done

Kubernets Docker Image

images=(
    k8s.gcr.io/kube-proxy:v1.15.5
    k8s.gcr.io/kube-apiserver:v1.15.5
    k8s.gcr.io/kube-controller-manager:v1.15.5
    k8s.gcr.io/kube-scheduler:v1.15.5
    k8s.gcr.io/coredns:1.3.1
    k8s.gcr.io/etcd:3.3.10
    k8s.gcr.io/pause:3.1
    quay.io/coreos/flannel:v0.11.0-amd64
)
for i in "${images[@]}"; do
    docker pull "$i"
done
docker save "${images[@]}" | gzip > k8s-images.tar.gz

Nginx controller

在 https://www.nginx.com/free-trial-request-nginx-controller/ 连接里可申请 Free Trial 镜像和许可文件。申请完成后可获得如下文件：

  • controller-installer-3.1.0.tar.gz

  • controller_license.txt

Nginx+

本部分需要在连网环境下进行，需要 NGINX Plus 的 License 证书, rpm 包同步完成后拷贝到离线环境。

1. 创建 /etc/ssl/nginx 目录，拷贝证书
# mkdir /etc/ssl/nginx

// copy license cert key to /etc/ssl/nginx
scp nginx-repo.* root@IP:/etc/ssl/nginx
2. 安装 ca-certificates 依赖
yum install ca-certificates -y
3. NGINX Plus yum 源配置
wget -P /etc/yum.repos.d https://cs.nginx.com/static/files/nginx-plus-7.4.repo
4. 下载 NGINX Plus rpm 包到本地目录
reposync -lmn --repoid=nginx-plus --download_path=/tmp/nginx/

tar -cf nginx-plus.tar nginx-plus/
5. 验证下载的 rpm 包
# tar -tf nginx-plus.tar

createuser db_user
createdb test_db
psql
ALTER USER db_user WITH ENCRYPTED PASSWORD 'db_pass'
ALTER USER db_user CREATEDB
GRANT ALL PRIVILEGES ON DATABASE test_db TO db_user
\q
8. 远程连接创建数据

Notehttps://nginx-controller.example.com/docs/ 里有详细关于 NGINX Controller 的文档。

3. License 激活

在 license 激活界面选择 controller_license.txt，即可激活，激活后界面如下:

Nginx Plus

本地 YUM 源配置

本部分基于 HTTP Web 服务器(Nginx 或 HTTPD)配置本地 YUM 源。

1. Web 服务器安装
// httpd
yum -y install httpd

// nginx
yum install nginx-plus -y
Note本部分可以两种 Web 服务器选择其一安装即可，如果选择 nginx，可以使用开源版本。
2. 拷贝 rpm 包，本地仓库初始化
mkdir -p /var/www/html/repos

tar -xvf nginx-plus.tar -C /var/www/html/repos

createrepo -v /var/www/html/repos/nginx-plus/ -o /var/www/html/repos/
createrepo --workers=5 /var/www/html/repos/
3. Web 服务器配置文件
// nginx
cat << EOF > /etc/nginx/conf.d/yum.conf
server {
        listen   80;
        server_name  yum.example.com;
        root   /var/www/html/repos;
        location / {
                autoindex on;
        }
}
EOF

// httpd
cat << EOF > /etc/httpd/conf.d/yum.conf
Alias /repo "/var/www/html/repos"
<Directory "/var/www/html/repos">
  Options +Indexes +FollowSymLinks
  Require all granted
</Directory>
<Location /repo>
  SetHandler None
</Location>
EOF
4. 启动 Web 服务器
// nginx
systemctl restart nginx ; systemctl enable nginx ; systemctl status nginx

// httpd
systemctl restart httpd ; systemctl enable httpd ; systemctl status httpd
5. 确保 http 服务没有被防火墙阻拦
firewall-cmd --zone=public --permanent --add-service=http
firewall-cmd --reload

安装

本部分在内网需要安装 nginx plus 的机器上进行。

1. 配置 yum 源
cat << EOF > /etc/yum.repos.d/nginx.repo
[nginx-plus]
baseurl = http://yum.example.com/repo/nginx-plus
enabled = 1
gpgcheck = 0
name = nginx-plus
EOF
2. 安装
yum install nginx-plus -y
systemctl start nginx
3. 访问测试
# echo "ok" > /usr/share/nginx/html/hello

# curl http://localhost/hello
ok
