使用rclone+nginx制作FTP镜像站——NOAA数据库分享的(最终?)解决方案

Web项目 Jason 5 years ago (2019-09-11) 1475 Views 1 Comments QR code of this page

还是NOAA数据库分享的问题,之前尝试了很多方案、出现了各种各样的问题:

  • 尝试1:用Python录入MySQL数据库,采取了大量的分表和分页优化查询速度,体积占到了3TB,买了一堆固态硬盘加速IO
  • 问题:体积太大、查询很慢、支持用户并发数低、成本太高、需要手动/脚本更新数据
  • ----------
  • 尝试2:用Python将数据格式化后按【站点】-【日期】的格式存放在不同目录下,每次用户填写表格使用PHP直接读取文件下载
  • 问题:体积略大、需要手动/脚本更新数据(其实这个方案用了挺久的,没有啥其他的毛病,但是每月要运行脚本更新数据好累啊)
  • ----------
  • 尝试3:用NextCloud挂载NOAA的FTP服务,然后分享账号和文件
  • 问题:NextCloud不会更新目录,而且文件数量太大经常崩溃(这是在本文要讲的方案之前使用的生产方案,也用了有半年了,不用再手动更新数据,而且还能卖账号!)

所以为了解决数据分享的问题,我又搞了个新方案:【Rclone挂载FTP配合Nginx的目录显示功能实现镜像站点的搭建】

此方案在写本文前已经使用了两个月了,非常非常稳定!如果不是服务器坏掉的话应该可以一直运行下去,也有一个缺点就是没有用户鉴权,其实可以加个nginx密码的,过段时间再说吧(小汤加油,顺便附上他博客:https://ivistang.cloudraft.cn/)。

教程正文:

这里选用的机器是Virmach家的黑五鸡肋鸡代号KVM-LA(真的很鸡肋很折腾 https://www.liujason.com/article/118.html),OS选的是CentOS-7-x64作为演示,其实都一样,看喜好吧。

1. 下载Rclone软件【偷懒的可以直接看2.2的一键包,不看这一步】
根据自己的Linux发行版安装即可,我之前写的一篇安装记录(https://www.liujason.com/article/244.html)是windows的,当时是为了挂载onedrive,Linux也是一样的,去下载即可。
官网下载链接:https://rclone.org/downloads/

这里我是amd64的Linux所以:

curl -O https://downloads.rclone.org/rclone-current-linux-amd64.zip

2. 下载好之后安装(2.1和2.2二选一)
2.1解压和添加到环境变量:

yum install unzip curl screen -y
#全新的minimal系统可能不含unzip和curl,安装了才行;screen是每次必装
unzip rclone-current-linux-amd64.zip
cd rclone-*-linux-amd64
#直接复制到bin里就可以了,记得该权限
sudo cp rclone /usr/bin/
sudo chown root:root /usr/bin/rclone
sudo chmod 755 /usr/bin/rclone
#安装manpage
sudo mkdir -p /usr/local/share/man/man1
sudo cp rclone.1 /usr/local/share/man/man1/
sudo mandb

2.2我在看官网的时候看到了一键包,这里也把代码放上来

yum install unzip curl -y
#全新的minimal系统可能不含unzip和curl,安装了才行
curl https://rclone.org/install.sh | sudo bash
#官网的一键脚本,省心呀

3. 使用rclone挂载FTP
rclone的基本使用方法参见--help,我在文末附录贴出来给大家参考。
我们这里主要使用的就是挂载功能,这里要注意,如果是用的容器而非完全虚拟化的话,需要给容器开启fuse功能(proxmox中的lxc需设置为privileged,总之就是要开启fuse)。

3.1 配置rclone
我们现在来配置rclone来挂载FTP,先输入命令rclone config,然后根据提示进行配置,我这里详细注释了(平时我绝对不会写这么详细的,为了给小汤学习这次写的特别细):

[root@KVM-LA ~]# rclone config
2019/09/12 03:42:06 NOTICE: Config file "/root/.config/rclone/rclone.conf" not found - using defaults
No remotes found - make a new one
n) New remote
s) Set configuration password
q) Quit config
n/s/q> n
#新建一个配置文件
name> noaa
#配置文件名
Type of storage to configure.
Enter a string value. Press Enter for the default ("").
Choose a number from below, or type in your own value
......
10 / FTP Connection
   \ "ftp"
......
Storage> 10
** See help for ftp backend at: https://rclone.org/ftp/ **
#选择FTP
FTP host to connect to
Enter a string value. Press Enter for the default ("").
Choose a number from below, or type in your own value
 1 / Connect to ftp.example.com
   \ "ftp.example.com"
host> ftp.ncdc.noaa.gov
#设置ftp服务器地址
FTP username, leave blank for current username, root
Enter a string value. Press Enter for the default ("").
user> anonymous
#设置账号
FTP port, leave blank to use default (21)
Enter a string value. Press Enter for the default ("").
port> 21
#设置端口
FTP password
y) Yes type in my own password
g) Generate random password
y/g> y
Enter the password:
password:
Confirm the password:
password:
#设置密码
Use FTP over TLS (Implicit)
Enter a boolean value (true or false). Press Enter for the default ("false").
tls> 
#设置是否使用TLS加密
Edit advanced config? (y/n)
y) Yes
n) No
y/n> n
Remote config
--------------------
[noaa]
type = ftp
host = ftp.ncdc.noaa.gov
user = anonymous
port = 21
pass = *** ENCRYPTED ***
--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y
Current remotes:

Name                 Type
====                 ====
noaa                 ftp

e) Edit existing remote
n) New remote
d) Delete remote
r) Rename remote
c) Copy remote
s) Set configuration password
q) Quit config
e/n/d/r/c/s/q> q
#接下来的就照着我这个填就好了

其中在设置FTP的时候要注意,如果是匿名FTP的话,有三种账号密码需要一个个尝试:
(1)用户名:anonymous 密码:Email
(2)用户名:FTP 密码:FTP或空
(3)用户名:USER 密码:pass
这里NOAA用的是第三个,我一个个试过了,只有这个可以

3.2 挂载rclone到系统存储
就和系统的mount挂载磁盘一样,挂载rclone虚拟盘同样也需要先新建一个目录才行:

sudo -u www mkdir /www/wwwroot/noaa-mirror.cloud.ac.cn/noaa -p
#注意,这里我把noaa这个路径放在了noaa-mirror.cloud.ac.cn网站(nginx)的目录下,这样是为了后续直接可以在网站的子路径中查看
#另外还要注意权限问题,切换一下用户

然后再挂载上去:

screen
#用screen后台运行
rclone mount noaa:/pub/data/ /www/wwwroot/noaa-mirror.cloud.ac.cn/noaa --read-only --copy-links --no-gzip-encoding --no-check-certificate --allow-other --allow-non-empty --umask 000
#格式为rclone mount 配置名称:远程路径 本地路径 --参数
#注意这里挂载的是noaa原镜像的子目录,因为上级目录中有很多是不需要的。

我在执行挂载的时候遇到了错误,实际上是缺失fuse库导致的,添加即可:

failed to mount FUSE fs: fusermount: exec: "fusermount": executable file not found in $PATH
yum install fuse -y

这时候重新挂载,然后退出screen,看看挂载情况:

[root@KVM-LA ~]# df -h
Filesystem       Size  Used Avail Use% Mounted on
/dev/vda1        9.6G  2.3G  6.9G  25% /
devtmpfs         7.8G     0  7.8G   0% /dev
tmpfs            7.8G   16K  7.8G   1% /dev/shm
tmpfs            7.8G   41M  7.8G   1% /run
tmpfs            7.8G     0  7.8G   0% /sys/fs/cgroup
tmpfs            1.6G     0  1.6G   0% /run/user/0
noaa:/pub/data/  1.0P     0  1.0P   0% /www/wwwroot/noaa-mirror.cloud.ac.cn/noaa

再看看路径下的情况,已经全部挂载上了:

cd /www/wwwroot/noaa-mirror.cloud.ac.cn/noaa
ls
.......

另外说一句,当fuse挂载后要卸载100%会卡住,要用lazy模式卸载(umount -l XXX)

------至此挂载FTP到本地磁盘的任务完成------

4. 通过Nginx将数据发布到网络中
4.1 利用新建一个静态网站
这一步很简单,yum也行,一键包也行,或者用AHM/宝塔面板也行,我就不多说了。

4.2 Nginx开启autoindex
虽然开启了网站,但是打开https://noaa-mirror.cloud.ac.cn/noaa/ 页面进去也是404,这是因为没有开启autoindex,导致Nginx自动查询“/noaa/”路径下的index.html文件,然后发现文件找不到,于是返回404错误代码。解决方法是在对应的conf文件中的server段里增加:

location / {
autoindex on;
autoindex_exact_size off; #这里是关闭精确显示大小,就会以MB之类的单位显示,否则会显示bytes Orz
autoindex_localtime on; #这里会使用服务器时间,否则是GMT
}

搞定之后重启Nginx就可以看到效果了
