Ubuntu build Seafile

Deploy Seafile server#

This document is used to explain how to install and run the Seafile server based on MySQL/MariaDB through the pre-compiled installation package. (MariaDB is a branch of MySQL)

download##

Go to download page to download the latest server installation package.

Deployment and catalog design##

Download seafile-server_6.2.5_* to your /home/username directory. Suggest a directory structure like this:

mkdir seafile
mv seafile-server_* seafile
cd seafile
# Seafile-server_*After moving to the seafile directory
tar -xzf seafile-server_*
mkdir installed
mv seafile-server_* installed

Your directory should now look like this:

# tree seafile -L 2
seafile
├── installed
│   └── seafile-server_xxxx.tar.gz
└── seafile-server-xxx
 ├── reset-admin.sh
 ├── runtime
 ├── seafile
 ├── seafile.sh
 ├── seahub
 ├── seahub.sh
 ├── setup-seafile.sh
 └── upgrade

**The advantage of designing the catalog this way is **

• All configuration files related to seafile can be placed in the seafile directory for centralized management.
• For subsequent upgrades, you only need to unzip the latest installation package to the seafile directory.

Install Seafile server##

Preparation before installation###

Before installing Seafile server, please confirm that the following software has been installed

• MariaDB or MySQL server (MariaDB is a branch of MySQL)
• python 2.7 (starting from Seafile 5.1, the minimum required python version is 2.7)
• python-setuptools
• python-imaging
• python-mysqldb
• python-ldap
• python-urllib3
• python-memcache (or python-memcached)

# on Debian/Ubuntu 14.04 server
apt-get update
apt-get install python2.7 libpython2.7 python-setuptools python-imaging \
 python-ldap python-mysqldb python-memcache python-urllib3

# on Ubuntu 16.04 server
# As the default python binary on Ubuntu 16.04 server is python 3, we need to install python(python 2) first.
apt-get update
apt-get install python
apt-get install python2.7 libpython2.7 python-setuptools python-imaging python-ldap python-urllib3 ffmpeg python-pip python-mysqldb python-memcache
pip install pillow moviepy

# on CentOS 7
yum -y install epel-release
rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro
yum -y install python-imaging MySQL-python python-memcached python-ldap python-urllib3 ffmpeg ffmpeg-devel
pip install pillow moviepy

installation###

cd seafile-server-*./setup-seafile-mysql.sh  #Run the installation script and answer preset questions

If one of the above software is not installed in your system, the Seafile initialization script will remind you to install the corresponding software package.

The script will ask you some questions in turn, and guide you step by step to configure the parameters of Seafile:

Here, you will be asked to choose a way to create a Seafile database:

-------------------------------------------------------
Please choose a way to initialize seafile databases:-------------------------------------------------------[1] Create newccnet/seafile/seahub databases
[2] Use existing ccnet/seafile/seahub databases

• If you select 1, you need to provide the root password. The script program will create the database and user.
• If you select 2, the ccnet/seafile/seahub database should have been created by you (or someone else) in advance.

If the installation is completed correctly, you will see the following output (the new version may be different)

Your directory structure should now look like this:

# tree seafile -L 2
seafile
├── conf                # configuration files
│   ├── ccnet.conf
│   └── seafile.conf
│   └── seahub_settings.py
│   └── seafdav.conf
├── ccnet
│   ├── mykey.peer
│   ├── PeerMgr
│   └── seafile.ini
├── installed
│   └── seafile-server_xxx.tar.gz
├── seafile-data
├── seafile-server-xxx  # active version
│   ├── reset-admin.sh
│   ├── runtime
│   ├── seafile
│   ├── seafile.sh
│   ├── seahub
│   ├── seahub.sh
│   ├── setup-seafile.sh
│   └── upgrade
├── seafile-server-latest  # symbolic link to seafile-server-xxx
├── seahub-data
│   └── avatars

The seafile-server-latest folder is a symbolic link to the current Seafile server folder. After you upgrade to a new version in the future, the upgrade script will automatically update to always point to the latest Seafile server folder.

Start Seafile server##

Start Seafile server and Seahub website###

In the seafile-server-xxx directory, run the following command

• Start Seafile:

. /seafile.sh start #Start Seafile service

• Start Seahub

. /seahub.sh start <port>  #Launch the Seahub website (runs on port 8000 by default)

**Tips: ** When you start seahub for the first time, the seahub.sh script will prompt you to create a seafile administrator account.

After the service starts, open the browser and enter the following address

http://192.168.1.111:8000/

You will be redirected to the login page. Just enter the administrator username and password.

Congratulations! Now you have successfully installed Seafile server.

Run Seahub on another port

If you don't want to run Seahub on the default port 8000, but want to run on a custom port (such as 8001), please follow the steps below:

• Shut down the Seafile server

. /seahub.sh stop #Stop the Seafile process
. /seafile.sh stop #Stop Seahub

• Change the value of SERVICE_URL in the haiwen/conf/ccnet.conf file (assuming your ip or domain name is 192.168.0.190), as follows (starting from version 5.0, you can set it directly in the administrator interface. Note, If this value is set in both the web interface and the configuration file, the configuration of the web interface shall prevail.):

SERVICE_URL = http://192.168.0.190:8001

• Restart Seafile server

. /seafile.sh start #Start Seafile service
. /seahub.sh start 8001 #Start the Seahub website (running on port 8001)

Close/restart Seafile and Seahub

shut down###

. /seahub.sh stop #Stop Seahub
. /seafile.sh stop #Stop the Seafile process

Restart###

. /seafile.sh restart #Stop the current Seafile process, then restart Seafile
. /seahub.sh restart  #Stop the current Seahub process and restart Seahub on port 8000

If the stopped/restarted script fails to run

In most cases the seafile.sh seahub.sh script can work normally. If you encounter problems:

• Use pgrep command to check whether the seafile/seahub process is still running

pgrep -f seafile-controller #View Seafile process
pgrep -f "seahub" #View Seahub process

• Use pkill command to kill related processes

pkill -f seafile-controller #End the Seafile process
pkill -f "seahub" #End the Seafile process

Boot from start

Use crontab's @reboot to set the boot-up auto-start, crontab -e enter the edit page and add:

@ reboot /home/username/seafile/seafile-server-latest/seafile.sh start &&/home/username/seafile/seafile-server-latest/seahub.sh start 8001

Automatically back up the database every day

The backup script is located in the /home/username/seafile/backup folder with the following content:

#! /bin/bash
user={database username}
pass={password}
datetime=`date +"%Y-%m-%d-%H-%M-%S"`
mysqldump -u $user -p$pass --opt ccnet-db >/home/username/seafile/backup/databases/ccnet/ccnet-db.sql.$datetime
mysqldump -u $user -p$pass --opt seafile-db >/home/username/seafile/backup/databases/seafile/seafile-db.sql.$datetime
mysqldump -u $user -p$pass --opt seahub-db >/home/username/seafile/backup/databases/seahub/seahub-db.sql.$datetime

Set a scheduled task in crontab to automatically back up the database every day:

01*** bash /home/username/seafile/backup/databases/seafile_backup.sh 2>&1&

Restore the backup database###

In the /home/username/seafile/backup/databases folder, there are three folders ccnet, seafile, and seahub to store the backup data of different libraries, and three database data need to be restored in sequence:

mysql -u[username]-p[password] ccnet-db < ccnet-db.sql.2013-10-19-16-00-05
mysql -u[username]-p[password] seafile-db < seafile-db.sql.2013-10-19-16-00-20
mysql -u[username]-p[password] seahub-db < seahub-db.sql.2013-10-19-16-01-05

Nginx reverse proxy external network access###

First, you need to have a server with a public IP, and then use OpenV** to build a V** network, and assign an IP: 10.8.0.190 to the intranet machines. Detailed method reference: [Ubuntu sets up OpenV** to achieve intranet penetration] (http://woodenrobot.me/2018/08/11/Ubuntu-%E6%9E%B6%E8%AE%BE-OpenV**-%E5%AE%9E%E7%8E%B0%E5%86%85%E7%BD%91%E7%A9%BF%E9%80%8F/)

1. Add the following Nginx configuration to reverse proxy on the machine where Seafile is located, so that you can access the Seafile homepage by accessing 192.168.0.190 from the intranet:

server {
 listen 80;
 server_name 192.168.0.19010.8.0.190 seafile.xxx.xxx;
 location /{
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_set_header Host $host;
  proxy_set_header X-Real-IP $remote_addr;
  proxy_pass http://192.168.0.190:8001;
  proxy_redirect default;}}

1. Add the following Nginx configuration on the machine with public IP:

server {
 listen 80;
 server_name seafile.xxxx.xxx;
 location /{
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_set_header Host $host;
  proxy_set_header X-Real-IP $remote_addr;
  proxy_pass http://10.8.0.190;}}
server {
 listen 8082;
 server_name seafile.xxx.xxx;
 location /{
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_set_header Host $host;
  proxy_set_header X-Real-IP $remote_addr;
  proxy_pass http://10.8.0.190:8082;
  proxy_redirect default;}}

Domain name intranet access to go intranet###

1. First, you need to use the Padavan old Maozi router system;
2. Enter the router background and open Internal Network (LAN)-DHCP Server;
3. Add the router hosts rule and set the router DNS address, and click to apply the settings on this page: 1192.168.0.190 seafile.xxx.xxx
4. Enter Ad Blocking Function-Adbyby, enable Adbyby function and enable redirection DNS, the redirection address is set to 192.168.0.1:
