I am using kernel 3.10 on CentOS 7. I have successfully installed CertBot 1.10.1 using alternative installation instructions as
certbot-auto successfully generated certificates for my nginx (1.7.8) installation. Simulating renewal with the
sudo /usr/local/bin/certbot-auto renew --dry-run was also successful.
The problem is that I can not find/confirm that certbot is actually installed for automatic launch. Docs indicate that CentOS EPEL 7 should use systemd. However, running
systemctl list-timers --all indicate that there is no timer set up for CertBot. There is nothing in
/etc/systemd/system/ related to CertBot. I have checked
crontab -l just in case -- nothing.
Why there is no auto-renewal set up?
Is it a mistake in the docs, or am I missing something?
Should I look elsewhere? Should I create the timer/job manually?
certbot 1.10.1 nginx 1.7.8 kernel 3.10.0-123.20.1.el7.x86_64 NAME="CentOS Linux" VERSION="7 (Core)" ID="centos" ID_LIKE="rhel fedora" VERSION_ID="7" PRETTY_NAME="CentOS Linux 7 (Core)" ANSI_COLOR="0;31" CPE_NAME="cpe:/o:centos:centos:7" HOME_URL="https://www.centos.org/" BUG_REPORT_URL="https://bugs.centos.org/" CENTOS_MANTISBT_PROJECT="CentOS-7" CENTOS_MANTISBT_PROJECT_VERSION="7" REDHAT_SUPPORT_PRODUCT="centos" REDHAT_SUPPORT_PRODUCT_VERSION="7"
P.S. I have used alternative installation method, because the default CertBot's installation with snapd does not work -- it complains:
error: system does not fully support snapd: cannot read the value of fs.may_detach_mounts kernel parameter: open /proc/sys/fs/may_detach_mounts: no such file or directory
which I assume means that my kernel version is too old for snapd to work.
