1.制作Nginx镜像
1.1 使用nginx：1.21.1官方镜像
# 下载官方镜像
docker pull nginx:1.21.1
# 打本地harbor的tag
docker tag 192.168.1.110/base/nginx:1.21.1
# 上传到本地harbor仓库
docker push 192.168.1.110/base/nginx:1.21.1
1.2 编写nginx配置文件的configmap的yaml并创建
k8s部署nginx时，在deployment yaml中使用configmap的方式挂载使用nginx配置文件
# nginx-configmap.yaml
cat nginx-configmap.yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: nginx-config
namespace: yan-test
data:
default: |
server {
listen 80;
server_name localhost;
location / {
root /var/www/html;
index index.html index.htm index.php;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /var/www/html;
}
location ~ \.php$ {
root /var/www/html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
location ~ /\.ht {
deny all;
}
}
# 创建
kubectl apply -f nginx-configmap.yaml
# 查看
# -n yan-test： namespace为yan-test
kubectl get configmaps -n yan-test
NAME DATA AGE
nginx-config 1 4d17h
2.制作PHP镜像
基础镜像使用Ubuntu20.04，打tag后上传到本地harbor仓库
2.1 制作镜像使用的文件列表
-rw-r--r-- 1 root root 4427 11月 4 11:40 php-fpm.conf
-rw-r--r-- 1 root root 74562 11月 4 10:44 php.ini
-rwxr-xr-x 1 root root 85 11月 5 18:39 run_php-fpm.sh*
-rw-r--r-- 1 root root 387 11月 5 16:33 sources.list
-rw-r--r-- 1 root root 18589 11月 4 11:54 www.conf
2.2 PHP镜像Dockerfile
FROM 192.168.1.110/base/ubuntu:20.04
COPY sources.list /etc/apt
COPY run_php-fpm.sh /
RUN apt update && \
DEBIAN_FRONTEND=noninteractive apt-get install software-properties-common -y && \
add-apt-repository ppa:ondrej/php -y && \
apt install --no-install-recommends --no-install-suggests -y inetutils-ping vim curl procps net-tools software-properties-common php5.6-fpm php5.6-mys
ql php5.6-curl php5.6-gd php5.6-mbstring php5.6-mcrypt php5.6-xml php5.6-xmlrpc php5.6-zip php5.6-opcache
COPY php-fpm.conf /etc/php/5.6/fpm/php-fpm.conf
COPY www.conf /etc/php/5.6/fpm/pool.d/www.conf
COPY php.ini /etc/php/5.6/fpm/php.ini
CMD ["/run_php-fpm.sh"]
2.3 PHP其他配置文件
# php-fpm.conf
注释以下行，否则启动php会提示找不到pid文件
#pid = /run/php/php5.6-fpm.pid
# php.ini
为了网站安全，将一下参数设置为0（关闭）
cgi.fix_pathinfo=0
# www.conf
在www模块开启9000端口监听
[www]
listen = 0.0.0.0:9000
2.4 run_php-fpm.sh PHP启动脚本
#!/bin/bash
/usr/sbin/php-fpm5.6 -y /etc/php/5.6/fpm/php-fpm.conf
tail -f /etc/hosts
2.5 构建镜像并上传到本地harbor
docker build -t 192.168.1.110/web/php:2021-11-5_1853 .
docker push 192.168.1.110/web/php:2021-11-5_1853
3.部署StatefulSet mysql一主多从集群
3.1部署
参考之前的另一篇博客：https://www.cnblogs.com/yanql/p/15440022.html
mysql-0主库容器的地址为：mysql-0.mysql.yan-test.svc.fx.local
yan-test: namespace
fx: k8s cluste name
3.2 为wordpress网站创建数据库，用户和用户密码。
mysql > CREATE DATABASE wordpress;
mysql > GRANT ALL PRIVILEGES ON wordpress.* TO 'worpress'@'%' IDENTIFIED BY 'wordpress';
4.部署WordPress
4.1 编写k8s的nginx，PHP的svc，deployment yaml
apiVersion: v1
kind: Service
metadata:
name: nginx-php
namespace: yan-test
spec:
type: NodePort
ports:
- name: http
port: 80
protocol: TCP
targetPort: 80
nodePort: 30080
selector:
app: nginx-php
---
apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx-deploy
namespace: yan-test
spec:
replicas: 1
selector:
matchLabels:
app: nginx-php
template:
metadata:
labels:
app: nginx-php
spec:
containers:
- name: nginx-ct
image: 192.168.1.110/base/nginx:1.21.1
imagePullPolicy: IfNotPresent
ports:
- containerPort: 80
protocol: TCP
name: http
resources:
limits:
cpu: 2
memory: 2Gi
requests:
cpu: 500m
memory: 1Gi
volumeMounts:
- name: php-html
mountPath: "/var/www/html"
- name: nginx-config
mountPath: "/etc/nginx/conf.d"
- name: php-ct
image: 192.168.1.110/web/php:2021-11-5_1853
imagePullPolicy: IfNotPresent
ports:
- containerPort: 9000
protocol: TCP
name: http
resources:
limits:
cpu: 2
memory: 2Gi
requests:
cpu: 500m
memory: 1Gi
volumeMounts:
- name: php-html
mountPath: "/var/www/html"
volumes:
- name: php-html
nfs:
server: 192.168.2.10
path: /data/k8s-data/nginx/html
- name: nginx-config
configMap:
name: nginx-config
items:
- key: default
path: default.conf
4.2 准备wordpress代码文件
wget https://cn.wordpress.org/wordpress-5.0.1-zh_CN.tar.gz
tar xf wordpress-5.0.1-zh_CN.tar.gz
# 将解压后的wordpress php代码移动到nginx容器中/var/www/html的挂载目录（NFS）
mv wordpress/* /data/k8s-data/nginx/html/
4.3 使用nginx-php.yml部署启动nginx，PHP容器
kubctl apply -f nginx-php.yml
kubectl get pod -n yan-test
NAME READY STATUS RESTARTS AGE
mysql-0 2/2 Running 0 4d18h
mysql-1 2/2 Running 1 4d18h
mysql-2 2/2 Running 1 4d18h
nginx-deploy-744c8fb58-4s9tg 2/2 Running 0 15m
4.4 配置代理
nginx:80 --> k8s svc (nginx-php):30080
server {
listen 80;
server_name yan.wd.com;
charset utf-8;
location / {
proxy_pass http://192.168.2.17:30080;
proxy_set_header Host $host;
}
}
