docker-stack一键编排lnmp

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> 
{
"CreatedAt"
: 
"2019-06-12T13:24:09+08:00"
,
"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_connections	
65535
;
}
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_timeout	
65
;  
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_pass 
127.0
.
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 = nginx
listen
 = 
127.0
.
0.1
:
9000
pm
 = dynamic pm.max_children =  
64
pm.start_servers
 = 
20
pm.min_spare_servers
 = 
5
pm.max_spare_servers
 = 
35
pm.max_requests
 = 
500
rlimit_files
 = 
1024
/<code>

4, 准备镜像

编写Dockerfile

<code>[root@nfs dockerfile] 

MAINTAINER [email protected]

RUN echo 
'Asia/Shanghai'
 > 
/etc/timezone
 && rm -f
/etc/nginx/nginx.conf && rm -f /usr/
local
/etc/php- fpm.d/www.conf

COPY 
localtime
 /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
/<code>

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
