启动容器

编写测试文件

index.html 
web-nginxinfo.php 
<?phpphpinfo(); 
?>

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
$host = 'mysql-master-0.mysql-master.mysql.svc.cluster.local';     // 数据库主机地址
$user = 'discuz';        // MySQL 用户名
$pass = '123.com';       // MySQL 用户密码
$dbname = 'discuz';      // 要连接的数据库名// 尝试连接 MySQL
$conn = new mysqli($host, $user, $pass, $dbname);// 检查连接错误
if ($conn->connect_error) {// 连接失败时终止脚本并输出错误die('连接失败：' . $conn->connect_error);
}// 连接成功，输出数据库版本信息
echo "MySQL 连接成功！数据库版本：" . $conn->server_info;
?>

<?php
$redis = new Redis();
try {// 连接Master（替换为你的实际地址和端口）$conn = $redis->connect('redis-master.redis.svc.cluster.local', 6379, 2); if ($conn) {echo "连接成功！";echo "Redis响应：" . $redis->ping(); // 测试服务响应} else {echo "连接失败（无错误信息）";}
} catch (RedisException $e) {// 打印具体错误（如：连接超时、拒绝连接、认证失败等）echo "Redis连接错误：" . $e->getMessage();
}

导入dicuz文件

docker cp ./  c37e6292ca17:/var/www/html/

修改属主

修改discuz默认配置（upload/config/）

config_global_default.php

数据库

从库

redis数据库

config_ucenter_default.php

镜像导出

[root@k8s-master web-nginx]# docker commit 9fbf6304f924 web-nginx:latest
sha256:79c04b1494346f3e4111229e2d902c40ee73c8beb1ad9d65df2111c0906fa73b
[root@k8s-master web-nginx]# docker save -o web-nginx.tar web-nginx:latest

镜像导入每个节点

部署web-nginx

编写启动文件

启动

访问

默认即可

问题

出现这个页面时，将redi缓存清理就ok

taomcat

自定义镜像

下载镜像

docker pull tomcat:8

生成测试镜像

docker run -itd --name tomcat -v /root/xm/tomcat/shangcheng/:/usr/local/tomcat/webapps/  --restart=always tomcat:8

sql文件拷贝给mysql库

注入sql语句

将复制的 sql文件内容拷贝到 configmap.yaml 文件中

主配置匹配cofihmap

     volumeMounts:- name: biyesheji-sqlmountPath: /docker-entrypoint-initdb.d/biyesheji.sqlsubPath: biyesheji.sqlvolumes:- name: biyesheji-sqlconfigMap:name: mysql-configitems:- key: biyesheji.sqlpath: biyesheji.sql

验证

编写镜像

修改商城默认配置

vim WEB-INF/classes/jdbc.properties

 vim /usr/local/tomcat/webapps/biyesheji/WEB-INF/classes/jdbc.properties

docker commit d44d4163 shangcheng:v1docker save -o shangcheng.tar   a4e0365

将镜像拷给各节点

docker tag a4e036 shangcheng:v1如果
REPOSITORY                                           TAG          IMAGE ID       CREATED         SIZE

结论

访问成功（/biyesheji/fore/foreIndex/）

discuz与nginx基于域名访问

拷贝镜像并导入

解压并提交

loadbalance模式

kubectl -n ingress-nginx edit svc ingress-nginx-controller

创建ip池

cat >IPAddressPool.yaml<<EOF
apiVersion: metallb.io/v1beta1
kind: IPAddressPool
metadata:name: planip-pool #这里与下面的L2Advertisement的ip池名称需要一样namespace: metallb-system
spec:addresses:- 192.168.111.140-192.168.11.170 #自定义ip段
EOF

关联IP池

cat >L2Advertisement.yaml<<EOF
apiVersion: metallb.io/v1beta1
kind: L2Advertisement
metadata:name: planip-poolnamespace: metallb-system
spec:ipAddressPools:- planip-pool #这里需要跟上面ip池的名称保持一致

提交

kubectl apply -f IPAddressPool.yaml
kubectl apply -f L2Advertisement.yaml

添加规则

kubectl apply -f ingress.yaml
