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

[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

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
