16--k8s之部署discuz项目

Discuz 2022-10-13

1.准备nginx文件，构建为镜像

1、创建目录
[root@docter ~]# mkdir /blog/{php,nginx,mysql}
[root@docter ~]# cd /blog/nginx/

2、编写nginx的dockerfile文件
[root@docter nginx]# cat Dockerfile 
FROM nginx
ADD nginx.conf /etc/nginx/nginx.conf
ADD default.conf /etc/nginx/conf.d/default.conf
RUN groupadd www -g 666 && \
    useradd www -u 666 -g 666 -M -r -s /sbin/nologin
ADD discuz /usr/share/nginx/html
RUN chown -R www.www /usr/share/nginx/html
WORKDIR  /usr/shar/nginx/html
EXPOSE 80 443
CMD nginx -g "daemon off;"

3、编写nginx的default.conf 文件
[root@docter nginx]# cat default.conf 
server {
    listen       80;
    listen  [::]:80;
    server_name  localhost;
    root   /usr/share/nginx/html;
    
    location / {
        index  index.php index.html index.htm;
    }

    location ~ \.php$ {
        root           /usr/share/nginx/html;
        fastcgi_pass   php:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
}

3、编辑nginx配置文件
[root@docker1 nginx]# vim nginx.conf 
user  www;
worker_processes  auto;

error_log  /var/log/nginx/error.log notice;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                  '$status $body_bytes_sent "$http_referer" '
                  '"$http_user_agent" "$http_x_forwarded_for"';

access_log  /var/log/nginx/access.log  main;

sendfile        on;
#tcp_nopush     on;

keepalive_timeout  65;

gzip  on;

include /etc/nginx/conf.d/*.conf;

4.上传discuz包
#上传，解压，只留upload，改名为discuz
[root@k8s-m-01 nginx]# ll
total 16
-rw-r--r--  1 root root  449 Aug 14 14:38 default.conf
-rw-r--r--  1 root root  325 Aug 14 14:38 Dockerfile
-rw-r--r--  1 root root  607 Aug 14 14:39 nginx.conf
drwxr-xr-x 13 root root 4096 Mar 22 19:44 upload

5、构建镜像
#在阿里云上面，先创建一个命名空间，再拉取镜像
[root@k8s-m-01 nginx]# docker build -t registry.cn-shanghai.aliyuncs.com/cdank8s/web:discuz-nginx-v1 .

#登录阿里云的本地仓库
[root@k8s-m-01 nginx]# docker login registry.cn-hangzhou.aliyuncs.com
Username: danlleee

#把镜像上传到阿里云
[root@k8s-m-01 nginx]# docker push registry.cn-hangzhou.aliyuncs.com/cdan-web/discuz:nginx-v1
The push refers to repository [registry.cn-hangzhou.aliyuncs.com/cdan-web/discuz]

#测试启动
[root@k8s-m-01 nginx]# docker run -d --name nginx registry.cn-hangzhou.aliyuncs.com/cdan-web/discuz:nginx-v1

[root@k8s-m-01 nginx]# docker ps -a | grep nginx
11b38bc51294   registry.cn-shanghai.aliyuncs.com/cdank8s/web:discuz-v1   "/docker-entrypoint.…"   27 seconds ago   Exited (1) 27 seconds ago             nginx
[root@k8s-m-01 nginx]# docker exec -it 11b38bc51294 bash
Error response from daemon: Container 11b38bc51294484e5c1f86110e2b01c68a36db683e4cbb3c6190c5392269d9bd is not running
[root@k8s-m-01 nginx]# ls
default.conf  discuz  Dockerfile  nginx.conf

2.构建php镜像

#上传php包
[root@k8s-m-01 php]# ll
total 19436
drwxr-xr-x 13 root root     4096 Mar 22 19:44 discuz
-rw-r--r--  1 root root      327 Aug 14 16:47 Dockerfile
-rw-r--r--  1 root root 19889622 Apr 28 10:39 php.tar.gz
-rw-r--r--  1 root root      463 Aug 14 16:39 www.conf

2、上传php.tar.gz
[rook8s-m-01 php]# wget http://www.mmin.xyz:81/package/lnmp/php.tar.gz

#编辑php Dockerfile
[root@docker php]# vim Dockerfile
FROM centos:7
RUN groupadd www -g 666 && \
    useradd www -u 666 -g 666 -M -r -s /sbin/nologin
ADD php.tar.gz /tmp
RUN yum -y localinstall /tmp/*.rpm
ADD www.conf /etc/php-fpm.d/
EXPOSE 9000
WORKDIR /usr/share/nginx/html
ADD discuz /usr/share/nginx/html
RUN chown -R www.www /usr/share/nginx/html
CMD php-fpm -F

 
 #discuze复制过来
[root@k8s-m-01 php]# cp ../nginx/discuz/ .

#创建PHP.repo
[root@k8s-m-01 php]# cat www.conf 
[www]
user = www
group = www
listen = 9000
request_terminate_timeout = 0
pm = dynamic
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 35
slowlog = /var/log/php-fpm/www-slow.log
php_admin_value[error_log] = /var/log/php-fpm/www-error.log
php_admin_flag[log_errors] = on
php_value[session.save_handler] = files
php_value[session.save_path]    = /var/lib/php/session
php_value[soap.wsdl_cache_dir]  = /var/lib/php/wsdlcache

#创建镜像
[root@k8s-m-01 php]# docker build -t registry.cn-hangzhou.aliyuncs.com/cdan-web/discuz:php-v1 .

#上传到本地
[root@k8s-m-01 php]# docker push registry.cn-hangzhou.aliyuncs.com/cdan-web/discuz:php-v1

3.创建yaml配置文件

# 1、编写mysql.yaml
[root@k8s-m-01 discuz]# vim mysql.yaml 
kind: Namespace
apiVersion: v1
metadata:
  name: mysql
---
kind: Deployment
apiVersion: apps/v1
metadata:

  type: NodePort

4.生成yaml文件

# 1、生成yaml文件
[root@k8s-m-01 blog]# kubectl apply -f web.yaml 
namespace/web created
deployment.apps/web created
service/web created

[root@k8s-m-01 blog]# kubectl apply -f mysql.yaml 
namespace/mysql created
deployment.apps/mysql created
service/mysql created

# 2、查看
[root@k8s-m-01 blog]# kubectl get pod -n web
NAME                   READY   STATUS    RESTARTS   AGE
web-7f897d448c-v5vbg   2/2     Running   0          69s
[root@k8s-m-01 blog]# kubectl get pod -n mysql
NAME                     READY   STATUS    RESTARTS   AGE
mysql-6f9b947c9f-25rrx   1/1     Running   0          5m54s

[root@k8s-m-01 blog]# kubectl get svc -n web 
NAME   TYPE       CLUSTER-IP    EXTERNAL-IP   PORT(S)        AGE
web    NodePort   10.96.59.89   <none>        80:31558/TCP   2m13s

# 3、IP访问
192.168.15.11:31558
