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

2.4 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
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"
2.5.2 远程测试
通过postman测试
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

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
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
3.4.2 运行前端
npm run serve
3.5 登录访问
使用账号admin,密码123456
