Memcached

Install and configure components

dnf -y install memcached python3-memcached

cp -p /etc/sysconfig/memcached{,_org}
ls -l /etc/sysconfig/memcached{,_org}

sed -i 's/127.0.0.1,::1/0.0.0.0,::/g' /etc/sysconfig/memcached
sed -i 's/127.0.0.1,::1/127.0.0.1,ctr01/g' /etc/sysconfig/memcached

※IPv6を無効化している場合は「::1」の削除が必須。

diff /etc/sysconfig/memcached{,_org}
cat /etc/sysconfig/memcached

Finalize installation

systemctl enable --now memcached.service
systemctl status --no-pager -l memcached.service
systemctl is-active memcached.service
systemctl is-enabled memcached.service
