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。

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。
