sinksmell / Lanblog

LanBlog 一站式个人博客解决方案

感谢以下开源项目作者及参与者的无私奉献

• Beego
• Vue
• D2Admin
• 其他相关开源项目

技术栈

Vue.js + axios(ajax) + Beego Restful api + Mysql + Nginx 目前已经进行初步容器化，可在 k8s 集群上快速部署

项目介绍

效果图

• 暂时只迁移一篇文章
• 演示地址

• 首页

• 侧边栏

• 阅读界面

• 后台登录界面

• 后台管理界面

安装&使用

• 以Ubuntu为例
• 必须要有能正常工作，拉取镜像的 k8s 集群

快速部署

• 首先需要一个可以工作的 k8s 集群
• Mysql 默认密码是 sinksmell
• 后台管理账号和密码均是 sinksmell
• 配置文件在 conf/app.conf 里面可以修改登录密码，但是要重新编译镜像，在yaml文件中替换镜像版本

# 测试一下 能否正常访问
# ps 在node上要通过clusterIp来访问service
# 在pod里可以直接通过 service name

4. 向外暴露服务

• 借助nginx向外暴露服务，需要事先安装 nginx 和 80，9090 两个端口

• 安装的Nginx有一个默认的Server 占用了 80 端口 手动删除

# 删除默认server
rm /etc/nginx/sites-enabled/default

# 拷贝lanblog.conf到 /etc/nginx/conf.d
 cp front/lanblog.conf /etc/nginx/conf.d/lanblog.conf
# 查看gateway服务的clusterIP 本例中是 10.152.183.118
kubectl  get svc
# 修改 /etc/nginx/conf.d/lanblog.conf 中的 proxy_pass 将 ip 替换为 上述ip
# 以下是修改后的结果
server {
    listen 80;
    server_name localhost;
    # access_log /root/blog.log  main;

    location / {
       proxy_pass http://10.152.183.118:80/ ;
    }
}

server {
    listen 9090;
    server_name localhost;
    # access_log /root/blog.log  main;

    location / {
       proxy_pass http://10.152.183.118:9090/ ;
    }

}

# 重新加载配置文件
nginx -s reload

5. 访问博客

1. 输入IP访问博客界面
2. 输入IP:9090访问后台管理界面
