K8s 管理系统项目[Linux环境–应用部署]

1. 启动数据库

1.1 配置yum仓库

rm -f /etc/yum.repos.d/*.repo
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
wget -O /etc/yum.repos.d/epel.repo https://mirrors.aliyun.com/repo/epel-7.repo

1.2 安装mariadb

mkdir -p /data/RPMS
cd /data/RPMS
wget https://downloads.mysql.com/archives/get/p/23/file/mysql-5.7.28-1.el7.x86_64.rpm-bundle.tar
tar xf mysql-5.7.28-1.el7.x86_64.rpm-bundle.tar
yum install ./*.rpm -y
systemctl enable --now mysqld

1.3 启动连接数据库

# 启动mysql
systemctl enable --now mysqld
# 取密码
grep pass /var/log/mysqld.log |awk '{print $NF}'
## 这里得到密码SYxFQYqA>2QM
# 登录mysql
mysql -uroot -p'SYxFQYqA>2QM'
# 重置localhost密码
set global validate_password_policy=0;
set global validate_password_length=1;
alter user 'root'@'localhost' identified by '123456';
# 创建远程用户(这里可以是其他用户名)
create user 'root'@'%' identified by '123456';

1.4 初始化数据库

create database k8s_dashboard charset utf8;

1.5 建表

use  k8s_dashboard
CREATE TABLE `workflow` ( 
	`id` int NOT NULL AUTO_INCREMENT,
	`name` varchar(32) COLLATE utf8mb4_general_ci NOT NULL,
	`namespace` varchar(32) COLLATE utf8mb4_general_ci DEFAULT NULL,
	`replicas` int DEFAULT NULL,
	`deployment` varchar(32) COLLATE utf8mb4_general_ci DEFAULT NULL,
	`service` varchar(32) COLLATE utf8mb4_general_ci DEFAULT NULL,
	`ingress` varchar(32) COLLATE utf8mb4_general_ci DEFAULT NULL,
	`type` varchar(32) COLLATE utf8mb4_general_ci DEFAULT NULL,
	`created_at` datetime DEFAULT NULL,
	`updated_at` datetime DEFAULT NULL,
	`deleted_at` datetime DEFAULT NULL,
	PRIMARY KEY (`id`) USING BTREE,
	UNIQUE KEY `name` (`name`)
	) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci;

1.5 数据库授权

grant all privileges on k8s_dashboard.* to 'root'@'%';
exit

2. 后端部署

2.4 运行环境

2.4.1 配置修改

这里需要修config/config.go的一些内容,将以下内容改为自己环境中数据库配置.
数据库创建详见https://blog.csdn.net/qq_29974229/article/details/129044435

	//数据库配置
	DbType = "mysql"
	DbHost = "192.168.31.24"
	DbPort = 3306
	DbName = "k8s_dashboard"
	DbUser = "root"
	DbPwd  = "123456"

修改Kubecofnig配置 config/config.go的第9行

	Kubeconfig = "config/cka"

将自己k8s服务器~/.kube/config取出来放到config/下,如果不改名的话,就把第9行改为config/config.否则就改为cka放到目录下覆盖原来文件即可.

可以用命令

# 这里192.168.31.57是本次部署节点的ip,替换这部分就可以了
sed -i 's/192.168.31.24/192.168.31.57/g' config/config.go

2.4.2 运行后端

go run main.go

这里如果卡住不动有2个可能

没有配置go代理,解决方法确认1.1的命令都被正常执行
数据库没有启动.

检查方法 telnet 1.4.1配置的地址和端口号
```
telnet 192.168.31.24 3306
```
如果端口通,确认DbName里的库是否创建,详见1.4.1

这里要多等一会

请添加图片描述

2.5 测试

2.5.1 本地测试

curl "http://127.0.0.1:9091/api/k8s/pods?namespace=default&filter_name=app-01-dffbb57c4-mzr67"

请添加图片描述

2.5.2 远程测试

通过postman测试

请添加图片描述

3. 前端部署

3.1 拉取代码

cd /data
git clone https://gitee.com/qqmiller/k8s-plantform-fe.git

输出结果

Cloning into 'k8s-plantform-fe'...
Username for 'https://gitee.com': qqmiller
Password for 'https://qqmiller@gitee.com': 
remote: Enumerating objects: 81, done.
remote: Counting objects: 100% (81/81), done.

remote: Total 81 (delta 23), reused 0 (delta 0), pack-reused 0
Unpacking objects: 100% (81/81), done.

3.2 安装npm

cd /data/
yum install gcc gcc-c++ -y
wget https://registry.npmmirror.com/-/binary/node/latest-v16.x/node-v16.15.0-linux-x64.tar.gz
tar xf  node-v16.15.0-linux-x64.tar.gz
rm -f node-v16.15.0-linux-x64.tar.gz
ln -sf /data/node-v16.15.0-linux-x64 /usr/local/node
echo 'export NODE_HOME=/usr/local/node' >> /etc/profile  
echo 'export PATH=$NODE_HOME/bin:$PATH' >> /etc/profile
source /etc/profile
echo 'export NODE_HOME=/usr/local/node' >> /etc/rc.local
echo 'export PATH=$NODE_HOME/bin:$PATH' >> /etc/rc.local
chmod +x /etc/rc.local

确认npm版本

node -v
    v16.15.0
npm -v
    8.5.5

3.3 安装依赖包

cd /data/k8s-plantform-fe/
npm install

请添加图片描述

3.4 运行环境

3.4.1 配置修改

如果前后端在一台服务器上,那么不需要修改.
如果在不同服务器或者pod上,修改src/views/common/Config.js搜索红框内的localhost改为后端的服务器ip即可

我这里api服务器ip是192.168.31.57

sed -i 's/localhost/192.168.31.57/g' /data/k8s-plantform-fe/src/views/common/Config.js

请添加图片描述

3.4.2 运行前端

npm run serve

请添加图片描述

3.5 登录访问

使用账号admin,密码123456

请添加图片描述
