环境要求
1, 配置nfs存储卷
1,在docker swarm集群中所有节点都确认安装nfs客户端软件
<code>/<code>
2, 在192.168.122.1 上搭建nfs,共享目录给docker swarm集群中所有节点挂载
<code>[root@nfs ~] [root@nfs ~] /opt/dockervolume *(rw,no_root_squash,sync) [root@nfs ~]/<code>
3, 在docker swarm集群中所有节点创建存储卷,并验证
<code> {

,"Driver"
:"local"
,"Labels"
: {},"Mountpoint"
:"/var/lib/docker/volumes/nginx_volume/_data"
,"Name"
:"nginx_volume"
,"Options"
: {"device"
:":/opt/dockervolume"
,"o"
"addr=192.168.122.1,rw"
, 注意这里的挂载参数要有"type"
:"nfs"
},"Scope"
:"local"
}local
nginx_volume nginx_volume/<code>2, 下载镜像
在任意能上外网的机器上操作
<code>[root@nfs ~]/<code>
3, 准备是相关配置文件
<code>[root@nfs ~] [root@nfs ~]/<code>
准备nginx主配置文件
<code>[root@nfs dockerfile] worker_processes auto; error_log /
var
/log/nginx/error.log warn; pid /var
/run/nginx.pid; events {use
epoll
; worker_connections65535
; } 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 sendfile /var
/log/nginx/access.log on; on; main; keepalive_timeout65
;include
/etc/nginx/conf.d/<code>准备nginx子配置文件
<code>[root@nfs dockerfile]
listen
80
; server_name_
;index
index.php index.html; root /var/www/html; location ~ \.php$ { fastcgi_pass127.0
.0
.1
:9000
; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } }/<code>准备时区文件
<code>[root@nfs dockerfile]/<code>
准备php-fpm子配置文件
<code>
[root@nfs dockerfile]
user
= nginx group = nginxlisten

.0.1
:9000
pm

pm.min_spare_servers
5
pm.max_spare_servers

pm.max_requests

/<code>4, 准备镜像
编写Dockerfile
<code>[root@nfs dockerfile] MAINTAINER daniel@itcast.cn RUN echo
'Asia/Shanghai'
>/etc/timezone
&& rm -f /etc/nginx/nginx.conf && rm -f /usr/local
/etc/php- fpm.d/www.conf COPYlocaltime
/etc/localtime
COPY nginx.conf /etc/nginx/nginx.conf COPY web.conf /etc/nginx/conf.d/web.conf COPY php-fpm-www.conf /usr/local
/etc/php-fpm.d/www.conf CMD /usr/sbin/nginx -c /etc/nginx/nginx.conf &&/usr/local
/sbin/php
-fpm -c /usr/local
/etc/php-fpm.conf/<code>构建镜像
<code>
[root@nfs
dockerfile]#
docker
build
-f
dockerfile
-t
192.168
.122
.18
/library/nginx-php-fpm:v1
.
/<code>上传镜像到harbor
<code>
[root@nfs
dockerfile]#
docker
login
192.168
.122
.18
[root@nfs
dockerfile]#
docker
push
192.168
.122
.18
/library/nginx-php-fpm:v1
5, 编排docker stack
编写YMAL文件
在docker swarm集群中的管理节点进行操作
<code>
[root@manager
~]#
cat discuz.yml version:
'3'
services: db:
image: 192.168.122.18/library/mysql:5.7 environment:
MYSQL_ROOT_PASSWORD:
123
MYSQL_DATABASE: discuz MYSQL_USER: discuz_user MYSQL_PASSWORD:
123
deploy:
replicas:
1
nginx-php:
image: 192.168.122.18/library/nginx-php-fpm:v1 depends_on:
-
db ports:
-
"8011:80"
volumes:
-
"nginx_volume:/var/www/html"
deploy:
replicas:
1
volumes:
nginx_volume: driver: local driver_opts:
type:
"nfs"
o:
"addr=192.168.122.1,rw"
device:
":/opt/dockervolume"
/<code>一键发布stack
<code>
~]# docker stack deploy -c discuz2.yml discuz
Creating
network discuz_default
Creating
service discuz_db
Creating
service discuz_nginx-php
/<code>6, 拷贝discuz代码到nfs共享
在nfs服务器上操作
<code>[root@nfs dockerfile] [root@nfs dockerfile] -rf cp: overwrite ‘/opt/dockervolume/index.php’? y/<code>
7, 通过浏览器安装
<code>[root@nfs dockerfile]/<code>
上图少了-R参数，请加上
