1. Wordpress架構

2. 構建wordpress鏡像

2.1 構建nginx-base-wordpress鏡像

Dockerfile

2.2 構建nginx-wordpress鏡像

Dockerfile

3. Wordpress k8s部署

3.1 pv和pvc

PV配置文件wordpress-persistentvolume.yaml

--- apiVersion: v1 kind: PersistentVolume metadata:name: wordpress-pvnamespace: wework spec:capacity:storage: 30GiaccessModes:- ReadWriteOncenfs:server: 192.168.31.109path: /data/k8s/wework/wordpress

PVC配置文件wordpress-persistentvolumeclaim.yaml

--- apiVersion: v1 kind: PersistentVolumeClaim metadata:name: wordpress-pvcnamespace: wework spec:volumeName: wordpress-pvaccessModes:- ReadWriteOnceresources:requests:storage: 10Gi

3.2 wordpress應用部署

此時Wordpress的Pod已經生成,且該pod里有2個container

通過控制臺訪問

創建了index.html后就能通過service轉發nginx訪問到頁面

創建index.php,通過nginx重定向到php

user nginx nginx; worker_processes auto; events {worker_connections 1024; } http {include mime.types;default_type application/octet-stream;sendfile on;keepalive_timeout 65;client_max_body_size 10M;client_body_buffer_size 16k;client_body_temp_path /apps/nginx/tmp 1 2 2;gzip on;server {listen 80;server_name blogs.magedu.net;location / {root /home/nginx/wordpress;index index.php index.html index.htm;}location ~ \.php$ {root /home/nginx/wordpress;fastcgi_pass 127.0.0.1:9000;fastcgi_index index.php;fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;include fastcgi_params;}error_page 500 502 503 504 /50x.html;location = /50x.html {root html;}} }

4. 部署Wordpress應用

4.1 下載并解壓Wordpress

下載Wordpress

root@haproxy-1:~# cd /data/k8s/wework/wordpress root@haproxy-1:/data/k8s/wework/wordpress# wget https://cn.wordpress.org/latest-zh_CN.tar.gz root@haproxy-1:/data/k8s/wework/wordpress# tar xf latest-zh_CN.tar.gz root@haproxy-1:/data/k8s/wework/wordpress# mv wordpress/* ./ root@haproxy-1:/data/k8s/wework/wordpress# rm -rf latest-zh_CN.tar.gz wordpress

4.2 配置負載均衡

修改haproxy

listen wordpress-80bind 192.168.31.188:80mode httpserver 192.168.31.111 192.168.31.111:30031 check inter 2s fall 3 rise 5server 192.168.31.112 192.168.31.112:30031 check inter 2s fall 3 rise 5server 192.168.31.113 192.168.31.113:30031 check inter 2s fall 3 rise 5

重啟haproxy

root@haproxy-1:~# systemctl restart haproxy

4.3 wordpress數據庫創建

mysql-0上

root@mysql-0:/# mysql Welcome to the MySQL monitor. Commands end with ; or \g.

這里的數據庫主機就是前幾日創建的StatefulSet的mysql.
