ku8eye web 开发环境

当前版本的 ku8eye web开发环境 以docker镜像方式提供,下载地址为: http://pan.baidu.com/s/1gdYk4CV

安装部署的架构图如下图所示。

注:运行ku8eye-web开发环境的服务器应在待安装Kubernetes集群的服务器范围之外,并能够与待安装服务器网络连通。

安装架构图

文件名为:ku8eye-web.tar.gz 用gunzip解压缩后,得到文件ku8eye-web.tar

导入docker镜像:

# docker load -i ku8eye-web.tar

给该镜像打上tag:

# docker tag 6f46b1372b52 ku8eye-web

运行开发环境: docker run -tid --name ku8eye-web -p 3306:3306 -p 8080:8080 -p 9001:9001 ku8eye-web 其中 3306 为mysql服务端口,8080 为tomcat服务端口,9001 为supervisor服务端口,均映射到宿主机上。

如需映射sshd的22端口,需添加一个 -p 参数,例如 -p 2222:22

容器启动成功后,需等待15秒左右,等待mysql数据库与web应用启动完成。

ku8eye-web的使用方式:

1. 命令行方式

进入容器:docker exec -ti ku8eye-web bash

使用命令行完成一键安装Kubernetes集群,脚本为:

/root/ku8eye-startup.sh $1 $2 $3

需要输入的3个参数为:

$1: 待安装主机IP地址列表,以逗号分隔。第一台主机将作为Kubernetes Master。例如:192.168.1.2,192.168.1.3

$2: docker0的B类IP地址,系统自动为每台主机设置docker0的C类地址,例如,输入 172.0.0.0/16,在两台机器上将分别设置docker0的地址为 172.0.1.0/24 和 172.0.2.0/24

$3: root用户的密码,目前仅支持所有主机相同的密码,例如:123456

一个完整的命令行如下: /root/ku8eye-startup.sh "192.168.1.2,192.168.1.3" "172.0.0.0/16" "123456"

注:每个参数需用双引号引起来

然后即可观察输出结果。

2. 网页方式

打开浏览器,地址栏输入宿主机IP和8080端口,即可进入ku8eye-web页面,对Kubernetes集群进行操作了。

登录账号:guest/123456

点击左侧“K8s Cluster”菜单,选择“Cluster Inf”进行安装。

安装架构图

---- 容器内包含的软件 ----

基础镜像为CentOS官方docker镜像:centos:latest

主要步骤:

1. 安装ansible,参考 centos-ansible镜像的Dockerfile

注:设置环境变量 ANSIBLE_HOST_KEY_CHECKING=false 表示ansible在ssh登录其他机器时,不执行基于known_hosts文件的 key checking 操作,这样能够跳过首次ssh连接需要输入yes的操作。

2. 为ansible安装 sshpass,并执行 ssh-keygen 生成密钥

3. 新增MariaDB.repo yum源配置,执行yum安装MariaDB-Server

MariaDB.repo配置如下:(根据MariaDB的更新,需要手工修改baseurl地址

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.1/centos7-amd64/
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=0

4. 安装 supervisor (pip install)

5. 复制 JRE1.8 到容器的 /root/jre1.8.0_65 目录,并设置环境变量 JAVA_HOME 和 PATH

6. 安装openssh

7. 复制安装Kubernetes所需的所有文件和ansible配置脚本到目录 /root/kubernetes_cluster_setup

8. 复制启动脚本、SQL脚本、配置文件到容器的 /root 目录

9. 复制配置文件 supervisord.conf 到容器的 /etc 目录

supervisord.conf文件内容如下:

其中,设置nodaemon为true 表示 supervisord 将在前台运行

通过supervisor将启动两个程序:sshd和 脚本run.sh

[supervisord]
nodaemon = true

[program:sshd]
command = /usr/sbin/sshd -D
autostart = true
autorestart = false
redirect_stderr = true

[program:ku8eye-web]
command = /root/shell_scripts/run.sh
autostart = true
autorestart = false
redirect_stderr = true

其中,/root/run.sh文件的内容包括启动mysql服务,创建ku8eye数据库,初始化数据,最后启动tomcat,内容为:

#!/bin/sh

# start mysqld service
/root/shell_scripts/run_mysqld.sh
# wait for mysqld to startup completely
sleep 5
echo "======`date +"[%Y-%m-%d %H:%M:%S]"` mysqld_safe start done. ======"

# run ku8eye-web initsql.sql to create user and tables
mysql < /root/db_scripts/initsql.sql
echo "======`date +"[%Y-%m-%d %H:%M:%S]"` create mysql tables for ku8eye-web done. ======"
sleep 1

# start ku8eye-web app
/root/shell_scripts/run_tomcat.sh
echo "======`date +"[%Y-%m-%d %H:%M:%S]"` start ku8eye-web done. ======"

run_mysqld.sh脚本的内容为:

nohup mysqld_safe &

run_tomcat.sh脚本的内容为:

nohup $JAVA_HOME/bin/java -jar /root/ku8eye-web.jar org.ku8eye.App > /root/tomcat.log 2>&1 &

最后,设置启动命令为 /usr/bin/supervisord

运行docker build完成镜像的创建

# docker build -t="ku8eye-web" --rm .

---- Ansible安装Kubernetes集群说明 ----

Ansible是一款基于Python开发的自动化运维工具,ku8eye-web通过调用 ansible-playbook 完成Kubernetes集群的一键安装。

1. Ansible 安装环境准备

1.1. 准备一台Linux服务器,安装docker。

1.2. 下载ku8eye web开发环境 docker镜像并启动容器(见本文开始章节的说明)。

2. Kubernetes集群环境准备

一个Kubernetes集群由etcd服务、master服务和一组node组成。 在无法访问Internet的环境,还需一台服务器作为docker private registry 私库,供Kubernetes使用。 本文以4台服务器为例,第一台安装docker registry,第二台安装etcd和master的服务,最后两台安装node所需服务。

系统要求: CentOS 7(RedHat 7)及以上版本,Linux 内核 3.10 及以上版本。 Kubernetes:推荐 v1.1 及以上版本 etcd:推荐v2.2 及以上版本 Docker:推荐 v1.9.0 及以上版本

服务器IP地址 作用
192.168.1.200 docker-registry
192.168.1.201 etcd
192.168.1.201 kube-master
192.168.1.202 kube-node
192.168.1.203 kube-node

注1:根据实际环境进行修改 注2:请勿将运行ansible的服务器纳入Kubernetes集群内。

3. Kubernetes集群安装前的准备工作

3.1 启动容器,进入容器

$ docker run -tid --name ku8eye-web -p 3306:3306 -p 8080:8080 -p 9001:9001 ku8eye-web $ docker exec -ti ku8eye-web bash

注:不进入容器,在安装服务器直接使用 docker exec 也可以完成ansible-playbook脚本的执行,注意配置文件需要使用全路径: $ docker exec -ti ku8eye-web ansible-playbook -i /root/kubernetes_cluster_setup/hosts /root/kubernetes_cluster_setup/pre-setup/ping.yml

3.2 修改 ansible 的 hosts 配置文件

修改/root/kubernetes_cluster_setup/hosts文件,内容为待安装Kubernetes集群各服务器的分组与IP地址。

注:通过修改hosts文件可以选择安装哪些role到哪些主机上。 每台服务器的用户名和密码分别设置

[docker-registry]
192.168.1.200 ansible_ssh_user=root ansible_ssh_pass=123456

[etcd]
192.168.1.201 ansible_ssh_user=root ansible_ssh_pass=123456

[kube-master]
192.168.1.201 ansible_ssh_user=root ansible_ssh_pass=123456

[kube-node]
192.168.1.202 ansible_ssh_user=root ansible_ssh_pass=123456
192.168.1.203 ansible_ssh_user=root ansible_ssh_pass=123456

3.4 执行ansible-playbook命令完成复制公钥操作:

$ ansible-playbook -i hosts pre-setup/keys.yml

192.168.1.203              : ok=2    changed=0    unreachable=0    failed=0   

keys.yml文件内容如下:

# Using this module REQUIRES the sshpass package to be installed!
#
# This REQUIRES you have created a ~/.ssh/id_rsa.pub public key
#
# Place the root password for all nodes in ~/rootpassword, run this playbook,
# and it will put your public key on all the nodes.  Then delete rootpassword!
#
# You can also comment out the "vars" section and use --ask-pass on the command
# line.
#
# All ansible modules will fail if the host is not in the ssh known_hosts.
# Normally ansible just asks if the host key is acceptable.  BUT when using
# password instead of public key authentication it will not ask and will instead
# fail.
#
# You can solve this by running a meaningless play to first get the ssh host
# key, then lay down the public key. Something like:
#       ansible-playbook -i inventory ping.yml
# Then answer yes as you check the host keys.
#
# You also could set the environment variable ANSIBLE_HOST_KEY_CHECKING=False
# when running this playbook.  You would have to answer the host key questions
# the next time you run ansible.
#

  tasks:
          - name: Push rsa public key to all machines
            authorized_key: user={{ ansible_ssh_user }} key="{{ lookup('file', '~/.ssh/id_rsa.pub') }}"

3.5 执行ansible-playbook命令停止所有机器的防火墙服务:

$ ansible-playbook -i hosts pre-setup/disablefirewalld.yml

192.168.1.203              : ok=3    changed=2    unreachable=0    failed=0   

disablefirewalld.yml文件内容如下:

---
- hosts: all
  tasks:
    - name: stop firewalld service
      command: systemctl stop firewalld

    - name: disable firewalld service
      command: systemctl disable firewalld

3.6 执行ansible-playbook命令为每台服务器添加docker registry服务器主机名与IP地址的host记录

注:本文中安装的docker registry将使用主机名作为私库的地址,如果希望使用IP地址,请修改相应的配置文件

# ansible-playbook -i hosts pre-setup/add_docker_registry_host.yml

add_docker_registry_host.yml文件内容如下:

---
- hosts: all
  tasks:
    - name: add host entry for docker private registry server
      shell: echo {{docker_registry_server_ip}} {{docker_registry_server_name}} >> /etc/hosts

其中参数 {{docker_registry_server_ip}} {{docker_registry_server_name}} 在 group_vars/all.yml 文件中进行配置。

4. Kubernetes集群安装

注:在 ku8eye-web 镜像中已创建好全部目录和文件,仅需修改配置文件的内容(详见 [4.6 修改配置文件的内容](#4.6 修改配置文件的内容) 一节的说明)

4.1 创建Role

在安装服务器的/root/kubernetes_cluster_setup目录下为不同的分组创建role(角色),包括:

  • docker-registry
  • etcd
  • kube-master
  • kube-node

4.2 在每个role下创建4个子目录:

defaults:存放变量的值,目录下main.yml文件将被ansible默认读取 files:存放需安装(复制)的源文件 tasks:ansible-playbook执行的任务脚本,目录下main.yml文件将被ansible默认读取 templates:需修改参数的配置文件,其中参数由defaults目录中的值进行替换

4.3 在安装服务器的/root/kubernetes_cluster_setup目录中创建group_vars子目录存放全局变量

默认文件为all.yml

4.4 在安装服务器的/root/kubernetes_cluster_setup目录中创建setup.yml文件,内容为ansible-playbook在各host安装role的配置:

---
- hosts: docker-registry
  roles:
    - docker-registry

- hosts: etcd
  roles:
    - etcd

- hosts: kube-master
  roles:
    - kube-master

- hosts: kube-node
  roles:
    - kube-node

  • quagga_router_image_id: f96cfe685533 quagga router 镜像ID
  • quagga_router_image_tag: index.alauda.cn/georce/router quagga router 镜像tag

6) 各node不同的参数,在主机列表kubernetes_cluster_setup/hosts 文件中进行设置

  • [docker-registry] 192.168.1.202

  • [etcd] 192.168.1.201

  • [kube-master] 192.168.1.201

  • [kube-node] 192.168.1.202 docker0_ip=172.17.1.1/24 docker_runtime_root_dir=/hadoop1/docker kubelet_hostname_override=192.168.1.202 install_quagga_router=false 192.168.1.203 docker0_ip=172.17.2.1/24 docker_runtime_root_dir=/hadoop1/docker kubelet_hostname_override=192.168.1.203 install_quagga_router=false

[kube-node] 参数说明: docker0_ip=172.17.1.1/24 docker0网桥的IP地址,每个node上设置为不同的IP地址 docker_runtime_root_dir=/hadoop1/docker docker运行根目录 kubelet_hostname_override=192.168.1.202 kubelet主机名 install_quagga_router=false 是否安装Quagga路由器(docker容器)

7) 修改 kubernetes_cluster_setup/setup.yml 脚本文件

该文件的内容表示在哪些主机组(从hosts中读取)上安装哪些role。 通过修改 hosts 文件 和 setup.yml 文件的内容来实现在不同机器上安装不同软件的场景。

  • 一个主机组可以安装多个role的内容

  • 多个主机组可以安装同一个role的内容


    • hosts: docker-registry roles:

      • docker-registry
    • hosts: etcd roles:

      • etcd
    • hosts: kube-master roles:

      • kube-master
    • hosts: kube-node roles:

      • kube-node

5.7 运行 ansible-playbook 完成集群的安装

$ ansible-playbook -i hosts setup.yml
