Taisomas Keydb



== Debian 9 (stretch) install ==

 wget https://download.keydb.dev/keydb-stable.tar.gz
 tar xzvf keydb-stable.tar.gz
 cd KeyDB/
 apt-get install build-essential nasm autotools-dev autoconf libjemalloc-dev tcl tcl-dev uuid-dev libcurl4-openssl-dev
 make distclean
 make && make install
 
Systemd service faila galima [[keydb.service|rasti cia]], jį dedame į '''/etc/systemd/system/keydb.service'''
Sukuriame failą /etc/keydb.conf ir sudedame keydb konfiguraciją kaip aprašyta žemiau:
<syntaxhighlight lang=text">

</syntaxhighlight>

Prieš įgalindami keydb servisą, turime išjungti senajį redis serverį.
 systemctl stop redis
 systemctl disable redis
Įjungiame keydb
 

== Kernel tune ==

 echo 'net.core.somaxconn=65365' >> /etc/sysctl.conf
 echo 'vm.overcommit_memory = 1' >> /etc/sysctl.conf
 sysctl -p
 echo never > /sys/kernel/mm/transparent_hugepage/enabled
