Installing Caddy 2 on Amazon Linux 2
The installation instructions of Caddy 2 for Fedora, RedHat
and CentOS seem to be quite easy. Amazon Linux 2 is based on RedHat Enterprise
Linux 5 and 6 (see Serverfault). Also
amazon-linux-extras talks about EPEL 7
(Extra Packages for Enterprise Linux):
# amazon-linux-extras […] 24 epel available [ =7.11 =stable ] […]
So this should be a quick thing – no? Let’s try:
$ yum -y install yum-plugin-copr […] Complete! $ yum -y copr enable @caddy/caddy Loaded plugins: copr, extras_suggestions, langpacks, priorities, update-motd copr done $ yum -y install caddy Loaded plugins: copr, extras_suggestions, langpacks, priorities, update-motd Resolving Dependencies --> Running transaction check ---> Package caddy.x86_64 0:2.6.2-1.el9 will be installed --> Processing Dependency: libc.so.6(GLIBC_2.34)(64bit) for package: caddy-2.6.2-1.el9.x86_64 --> Finished Dependency Resolution Error: Package: caddy-2.6.2-1.el9.x86_64 (copr:copr.fedorainfracloud.org:group_caddy:caddy) Requires: libc.so.6(GLIBC_2.34)(64bit) You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest
OK, the installed version of
libc is too old.
Of course some other people did have the same problem (see StackOverflow) but the answer suggests compiling from source. That’s a possible solution but I don’t like the burden of maintaining the installation for myself.
The installation page features the link View the Caddy COPR which offers more options and mentions RHEL 7. So it should work. The installation instructions for RHEL 7 on that page are the same as on the main page. But I noticed a little syntax twist in the section for CentOS Stream 91:
dnf copr enable @caddy/caddy epel-9-$(arch)
Perhaps this additional “chroot” argument is applicable for Amazon Linux 2 also – with some adaptions? After cleaning up the previous attempt I tried this:
$ yum -y install yum-plugin-copr $ yum -y copr enable @caddy/caddy epel-7-$(arch) $ yum -y install caddy
And that one worked!
Update 2023-02-25: This worked for me only on a fresh
install. If the “normal” installation commands had been executed on the
copr enable command without the
then a simple
yum -y copr disable @caddy/caddy followed by the “good”
copr enable command did not work! After
copy disable I had to delete some
random cached files. But now
copr disable followed by
copr enable works
for me, too.
Update 2023-02-25: Now this line has been changed and the last argument has been deleted. ↩︎
