erpnext 为开源的erp系统，采用python语言编写，本次部署采用windows7+docker方式进行，erpnext需要运行python、redis、mariadb或者mysql、nginx。

参考资料

docker镜像

erpnext基于ubuntu操作系统构建。

pull erpnext镜像

docker pull lukptr/erpnext7

运行erpnext

docker run -d --name erpnext -p 80:80 lukptr/erpnext7

启动之后访问虚拟机ip地址就可以，比如 192.168.99.100

登录名：Administrator 密码：12345678

这种方式运行之后，数据没有得到持久化，db数据没有持久化，app数据没有进行持久化，如果程序发生错误，下次再次运行erpnext时，数据就会消失。

erpnext 数据持久化

通过docker的volume方式，把docker容器的数据持久化到宿主机。

site1.local 目录数据持久化

把容器里面的site1.local目录复制到windows7系统，在做操作之前，把windows7的F盘共享给docker宿主机

docker cp erpnext:/home/frappe/frappe-bench/sites/site1.local /F/DataAgg/erpnext/frappe/

如下：

docker@dataagg:/F/DataAgg/erpnext/frappe/site1.local$ ls -la

total 9

drwxrwxrwx 1 docker staff 4096 Mar 20 08:13 ../

drwxrwxrwx 1 docker staff 0 Mar 19 17:07 task-logs/

docker@dataagg:/F/DataAgg/erpnext/frappe/site1.local$

db数据持久化

docker cp erpnext:/var/lib/mysql /F/DataAgg/erpnext/

把mysql的数据复制到F:\DataAgg\erpnext\mysql下面，下次启动erpnext时候，映射到宿主机

执行docker数据持久化命令:

docker run -d --name erpnext -v /F/DataAgg/erpnext/mysql/:/var/lib/mysql/ -v /F/DataAgg/erpnext/frappe/site1.local:/home/frappe/frappe-bench/sites/site1.local -v /F/DataAgg/erpnext/logs:/home/frappe/frappe-bench/logs -p 80:80 lukptr/erpnext7

进入容器查看mysql数据权限不对，如下：

# pwd

/var/lib/mysql

# ls -la

通过上面pid可以发现，mysqld的pid一直在递增，说明mysqld服务一直在重启。

由于mysql数据目录的用户和属组没有成功改成mysql，导致mysql服务一直起不来。初步判断是因为共享机制的问题，windows7的数据共享个docker 宿主机，docker宿主机再次把数据映射到docker erpnext容器。其他windows系统可以尝试上面的方法持久化mysql数据。在linux下面采用这种方式没有问题，已经测试可以使用。

采用外部mariadb数据库

由于windows7的共享机制尝试失败，采用外部db作为erpnext存储，达到持久化数据目的。

修改F:\DataAgg\erpnext\frappe\site1.local目录下面的site_config.json文件内容

{

"db_host": "192.168.10.234",

"db_name": "erpnext",

"db_user": "erpnext",

"db_password": "erpnext"

}

修改mariadb的配置文件

[mysqld]

innodb-file-format=barracuda

innodb-file-per-table=1

innodb-large-prefix=1

character-set-client-handshake = FALSE

character-set-server = utf8mb4

collation-server = utf8mb4_unicode_ci

运行erpnext容器，备份mysql数据

docker run -d --name erpnext -v /F/DataAgg/erpnext/frappe/site1.local:/home/frappe/frappe-bench/sites/site1.local \

-p 80:80 lukptr/erpnext7

# cd /home/frappe/frappe-bench

# bench backup

# pwd

/home/frappe/frappe-bench/sites/site1.local/private/backups

# ls -la

#

启动20170320_163732_b350d2cf_database.sql.gz文件为备份的sql文件

在外部db执行备份的sql文件

最终采用下面命令启动erpnext

docker run -d --name erpnext -v /F/DataAgg/erpnext/logs:/home/frappe/frappe-bench/logs -v /F/DataAgg/erpnext/frappe/site1.local:/home/frappe/frappe-bench/sites/site1.local -p 80:80 lukptr/erpnext7

访问192.168.99.100进入登陆界面，默认的用户名Administrator 密码 12345678，app数据和db数据得到持久化处理。
