JOduMonT b0df1b0667 vm.overcommit_memory & transparent_hugepage (#154 )

as recommanded by REDIS
\#WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.

\# WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.

add kernel parameter

cat > /etc/sysctl.d/libresh.conf <<EOF

vm.max_map_count=262144
vm.overcommit_memory=1
EOF
chmod 644 /etc/sysctl.d/libresh.conf
sysctl -p

echo never > /sys/kernel/mm/transparent_hugepage/enabled

Remark I did a variante to find the last version of DockerCompose and download it

mkdir -p /opt/bin &&\
dockerComposeVersion=$(curl -s https://api.github.com/repos/docker/compose/releases/latest|grep tag_name|cut -d'"' -f4) &&\
curl -L https://github.com/docker/compose/releases/download/$dockerComposeVersion/docker-compose-`uname -s`-`uname -m` > /opt/bin/docker-compose &&\
chmod +x /opt/bin/docker-compose

install Libre.sh

git clone https://github.com/indiehosters/libre.sh.git /libre.sh &&\
mkdir /{data,system} &&\
mkdir /data/trash &&\
cp /libre.sh/unit-files/* /etc/systemd/system && systemctl daemon-reload &&\
systemctl enable web-net.service &&\
systemctl start web-net.service &&\
cp /libre.sh/utils/* /opt/bin/

add /opt/bin path

cat > /etc/profile.d/libre.sh <<EOF
export PATH=$PATH:/opt/bin
