1、构建镜像 nginx、php、mysql 要求使用centos7作为基础镜像
2、使用deployment部署上面的容器,要求3个服务要放到一个pod中(虽然这样是不对的)
3、使用ingress 将上面部署的服务发布出去,通过访问nginx下的index.php访问链接到mysql数据库
4、nginx 和php 要求挂载宿主机的/apps/data/的目录做存储
0、docker镜像加速配置留存 我自己常用的一些加速源,如果你没有配置过就把下面的加上重启docker服务 vi /etc/docker/daemon.json
{exec-opts: [native.cgroupdriversystemd],registry-mirrors: [http://hub-mirror.c.163.com,https://cn-north-4.mirror.huaweicloud.com,https://registry.docker-cn.com,https://mirror.ccs.tencentyun.com,https://b9pmyelo.mirror.aliyuncs.com],insecure-registries: [10.0.16.15:30007]

ENV PATH /usr/local/nginx/sbin:$PATH
WORKDIR /usr/local/nginx/
EXPOSE 80
CMD [nginx,-g,daemon off;]构建
docker build . -f Dockerfile -t lnmp/nginx:v1 4、部署lnmp
#主页文件挂在路径

部署
kubectl apply -f lnmp.yaml 5、配置php访问页面
vi /apps/data/index.php
?phpphpinfo();
?
访问
http://101.43.156.78:30010/index.php 6、配置php链接mysql测试
vi /apps/data/conn.php
?php
$linkmysqli_connect(localhost:3306,sun,123);
if($link) echo 数据库链接成功;
mysqli_close($link);
?
mysql授权
#登录容器
kubectl exec -it my-deployment-5bb547dc98-2qj77 -c mysql-container bash#授权
mysql -e GRANT ALL PRIVILEGES ON *.* TO sunlocalhost IDENTIFIED BY 123;#上面没有要求做mysql的持久化,这里重新部署容器的时候这个权限要重新赋予
访问
http://101.43.156.78:30010/conn.php 7、配置ingress控制器
安装
cd /apps/build
wget https://ghproxy.com/https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.3.1/deploy/static/provider/cloud/deploy.yaml
替换镜像
sed -i s#registry.k8s.io/ingress-nginx/controller:v1.3.1sha256:54f7fe2c6c5a9db9a0ebf1131797109bb7a4d91f56b9b362bde2abd237dd1974#registry.cn-hangzhou.aliyuncs.com/google_containers/nginx-ingress-controller:v1.3.1#g deploy.yaml

添加主机网络模式
awk /containers:/ {print hostNetwork: true} 1 deploy.yaml ingress-controller.yaml
rm -f deploy.yaml 部署
kubectl apply -f ingress-controller.yaml 查看
kubectl get pod,svc,ing,deploy -n ingress-nginx 这里Completed是正常的 8、部署http-backend
vi http-backend.yaml
apiVersion: apps/v1

spec:ports:- port: 80targetPort: 8080selector:k8s-app: default-http-backend部署
kubectl apply -f http-backend.yaml 9、添加ingress-nginx规则
vi ingress-nginx.yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:name: nginx
spec:ingressClassName: nginxrules:- host: www.han.comhttp:paths:- path: /pathType: Prefixbackend:service:name: nginx-php-mysqlport:number: 80 部署
kubectl apply -f ingress-nginx.yaml
查看 kubectl describe ingress nginx 10、访问域名测试
vi /etc/hosts
10.0.16.15 www.han.com 访问
curl www.han.com/conn.php 二、部署mysql主从
1、使用statefulset 控制器部署mysql:8.0 要求副本数为2且为主从关系
2、使用无头svc 发布,名称为mysql-headless
3、使用ingress发布mysql 端口为30012
4、使用动态存储卷(nfs),存储mysql数据
0、准备nfs共享 我集群就1台主机 随便放了 yum install nfs-utils -y
mkdir -p /apps/mysql_master_slave/data/{mysql-0,mysql-1}
echo /apps/mysql_master_slave/data/mysql-0 *(rw,no_root_squash) /etc/exports
echo /apps/mysql_master_slave/data/mysql-1 *(rw,no_root_squash) /etc/exports
systemctl restart nfs-server
1、创建持久卷
cd /apps/mysql_master_slave
vi mysql-pv.yaml
apiVersion: v1
kind: PersistentVolume
metadata:name: pv-a # 为持久化卷A指定名称
spec:capacity:storage: 1GiaccessModes:- ReadWriteOnce- ReadOnlyManypersistentVolumeReclaimPolicy: Recyclenfs:server: 10.0.16.15path: /apps/mysql_master_slave/data/mysql-0 # 指定NFS路径---apiVersion: v1
kind: PersistentVolume
metadata:name: pv-b # 为持久化卷B指定名称
spec:capacity:storage: 1GiaccessModes:- ReadWriteOnce- ReadOnlyManypersistentVolumeReclaimPolicy: Recyclenfs:server: 10.0.16.15path: /apps/mysql_master_slave/data/mysql-1 # 指定NFS路径
部署
kubectl apply -f mysql-pv.yaml#查看
kubectl get pv 2、编辑mysql主从配置
vi mysql-configmap.yaml
apiVersion: v1
kind: ConfigMap
metadata:name: mysqllabels:app: mysql
data:master.cnf: |# Apply this config only on the master.[mysqld]log-binslave.cnf: |# Apply this config only on slaves.[mysqld]super-read-only
部署
kubectl apply -f mysql-configmap.yaml
3、部署无头svc
vi mysql-headless-svc.yaml
apiVersion: v1
kind: Service
metadata:name: mysql-headlesslabels:app: mysql
spec:ports:- name: mysqlport: 3306clusterIP: Noneselector:app: mysql
部署
kubectl apply -f mysql-headless-svc.yaml
4、部署mysql服务
vi mysql-sts.yaml
apiVersion: apps/v1
kind: StatefulSet
metadata:name: mysql-ss

部署
kubectl apply -f mysql-sts.yaml#查看
kubectl get pod 5、验证mysql主从是否正常
kubectl exec -it mysql-ss-1 -- bash
mysql -e SHOW SLAVE STATUS\G | grep -E Slave_IO_Running|Slave_SQL_Running 登录mysql-0 新增数据去mysql-1 查看 #数据库1
create database ui;
create table ui.user(name varchar(255));
insert into ui.user(name) values(jstang);#数据库2
select * from ui.user; 6、ingres发布mysql 没整过先略下面是废话跳过直接看三 对于使用 StatefulSet 部署的 MySQL您可以通过 Ingress 来进行访问。然而需要注意的是由于 MySQL 使用的是 TCP 协议而不是 HTTP/HTTPS传统的 Ingress 无法直接代理 TCP 流量。不过Kubernetes 社区提供了一种叫做 TCP Ingress 的解决方案可以用来代理 TCP 流量包括 MySQL。

1、使用deployment部署zabbix,并使用daemonSet部署zabbix-agent
2、启动zabbix-UI页面后,选定指定的主机的物理ip才可访问(hostport nodeSelector)
3、zabbix上可以监控上题的所有pod中的mysql(需要导入mysql监控模板)0、准备nfs目录
mkdir -p /apps/zabbix/data
echo /apps/zabbix/data *(insecure,rw,sync,no_root_squash) /etc/exports
exportfs -r 1、部署zabbix-mysql
cd /apps/zabbix
kubectl create namespace zabbix

1、使用Deployment创建两个Pod一个Pod为DNS主服务器另一个Pod为DNS从服务器
2、DNS子域可以解析域名第一题中的ingress地址
3、单独创建一个pod,指定dns为dns从服务器并且访问第一题中的域名要正常打开 略有空在看
