Notes install Seafile Apache RedHat7 Memcached MySQL/MariaDB

Install Seafile avec MySQL / MariaDB

MySQL doit être démarré

Voir : 

yum install python-distribute python-imaging MySQL-python python-memcached python-ldap
 
#adduser --system seafile --shell /sbin/nologin -m
adduser --group --system --disabled-password seafile
su - seafile -s /bin/bash
 
mkdir foo1
cd foo1
wget https://bintray.com/artifact/download/seafile-org/seafile/seafile-server_5.1.2_x86-64.tar.gz
tar xvf ../seafile-server_5.1.2_x86-64.tar.gz
 
Seafile avec MySQL Voir http://manual.seafile.com/deploy/using_mysql.html
 
./setup-seafile-mysql.sh

La 1er fois lancer 

./seafile.sh start

Puis (c'est à cette étape que compte admin sera crée) ./seahub.sh start <port> Site Web. Port par défaut : TCP 8000 

./seahub.sh start

Arrêt 

./seahub.sh stop
./seafile.sh stop

Install de memcached

Voir http://manual.seafile.com/deploy/add_memcached.html 

yum install memcached
systemctl enable memcached
systemctl start memcached

Solution

Source https://forum.ubuntu-fr.org/viewtopic.php?id=1080701 

wget https://bugs.archlinux.org/task/20374\?getfile\=5563 -O  cism216.fw
mkdir /usr/share/sane/gt68xx/
cp cism216.fw /usr/share/sane/gt68xx/
chmod -R a=rwX /usr/share/sane/gt68xx
cp -p /etc/sane.d/gt68xx.conf{,.orig}
vim /etc/sane.d/gt68xx.conf

Il faut ajouter les lignes suivantes : 

override "plustek-opticslim-1200"
firmware "/usr/share/sane/gt68xx/cism216.fw"

Ça doit ressembler à

/etc/sane.d/gt68xx.conf
