So I am installing Zabbix. Why, well, you probably know. If not, we can talk about that in a different article. Yes I am testing my ansible playbook in a docker container, but right now that too is not important. The How I did It will be in a different article. This article is the Everything That Went Wrong and How I Got Around That one. Think of it as an insight of how I deal with me being clueless; laughing at my expense is acceptable and maybe even recommended.
I want to install latest version of Zabbix in a CentOS 7 host, as a result I will be using the official zabbix 3.2 install docs, which are the most current when I wrote this article. For now I will be lazy and use the mysql version since it is faster to setup; we can revisit that later.
Dependencies
Need the repo. Per the official Zabbix instructions, I am using the official Zabbix repo, which as of the time of this writing can be obtained by
rpm -ivh http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm
I did write a script to get the latest rpm, but it is not important right now. Now, if you are curious, here is the repo config file:
[root@zabbix ~]# cat /etc/yum.repos.d/zabbix.repo [zabbix] name=Zabbix Official Repository - $basearch baseurl=http://repo.zabbix.com/zabbix/3.2/rhel/7/$basearch/ enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591 [zabbix-non-supported] name=Zabbix Official Repository non-supported - $basearch baseurl=http://repo.zabbix.com/non-supported/rhel/7/$basearch/ enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX gpgcheck=1 [root@zabbix ~]#
Before you ask, I am making a point to accidentally post it here for a reason, which will become clearer later.
The database server. Thanks to irc user leManu enlightening me, we are not supposed to install mysql (or whatever db) server on the machine that will run zabbix server. With that said, the line
mysql> grant all privileges on zabbix.* to zabbix@localhost identified by '
'; in the official docs has a very localhost feel to it.
We better build the db server first, and then go there and create the zabbix user, tying it to the IP for the zabbix server. I used mariadb and then grabbed the required -- FQDN, port, zabbix password -- info and came back to the zabbix server.
Packages. We have the repo setup, and database server info on standby. We might as well start installing zabbix itself, right?
[root@zabbix ~]# yum install zabbix-server-mysql zabbix-web-mysql [...] --> Finished Dependency Resolution Error: Package: zabbix-server-mysql-3.2.4-2.el7.x86_64 (zabbix) Requires: fping Error: Package: zabbix-server-mysql-3.2.4-2.el7.x86_64 (zabbix) Requires: libiksemel.so.3()(64bit) You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest [root@zabbix ~]#Bummer. Why didn't it grab them from the normal centos repo? I guess maybe it does not have them and we will need to fetch them from another repo. But, before we add another repo, do you remember the file /etc/yum.repos.d/zabbix.repo, whose contents we pasted earlier? It has a zabbix-non-supported; how about if we take a quick look there?
[root@zabbix ~]# yum whatprovides */fping --enablerepo=zabbix-non-supported Loaded plugins: fastestmirror, ovl Loading mirror speeds from cached hostfile * base: mirrors.gigenet.com * extras: mirror.keystealth.org * updates: mirror.umd.edu fping-3.10-1.el7.x86_64 : Scriptable, parallelized ping-like utility Repo : zabbix-non-supported Matched from: Filename : /usr/sbin/fping fping-3.10-1.el7.x86_64 : Scriptable, parallelized ping-like utility Repo : @zabbix-non-supported Matched from: Filename : /usr/sbin/fping [root@zabbix ~]#
Short version: grab the two packages we need from it already:
yum install fping iksemel --enablerepo=zabbix-non-supported
Missing setup file (thanks Yum!). Per the docs, we are now supposed to grab a file called /usr/share/doc/zabbix-server-mysql-3.2.4/create.sql.gz and use it to initially populate the zabbix database. Thing is, I can't find that (/usr/share/doc/zabbix-server-mysql-3.2.4) directory, much less the file:
[root@zabbix ~]# ls /usr/share/doc/ coreutils-8.22 pam-1.1.8 python-pycurl-7.19.0 gnupg2-2.0.22 pygpgme-0.3 unixODBC-2.3.1 krb5-libs-1.13.2 python-kitchen-1.1.1 zabbix-release-3.2 [root@zabbix ~]#
Maybe /usr/share/doc/zabbix-release-3.2/ is the directory and the docs were off? I will have to expertly crush your hopes:
[root@zabbix ~]# ls /usr/share/doc/zabbix-release-3.2/ GPL [root@zabbix ~]# ls -l /usr/share/doc/zabbix-release-3.2/ total 20 -rw-r--r-- 1 root root 18385 Feb 15 2016 GPL [root@zabbix ~]# head -10 /usr/share/doc/zabbix-release-3.2/GPL ***************************************************************************** The following copyright applies to the Red Hat Linux compilation and any portions of Red Hat Linux it does not conflict with.

Nope.
[root@zabbix ~]# find / -name create.sql.gz -print [root@zabbix ~]#
So, where's it? Hey, don't look at me like that. I too have no idea. Let's grab the rpm and then take a look at it:
root@zabbix:/tmp$ rpm -qlp zabbix-server-mysql-3.2.4-2.el7.x86_64.rpm | grep cre ate.sql.gz warning: zabbix-server-mysql-3.2.4-2.el7.x86_64.rpm: Header V4 DSA/SHA1 Signatur e, key ID 79ea5ed4: NOKEY /usr/share/doc/zabbix-server-mysql-3.2.4/create.sql.gz root@zabbix:/tmp$
That is the version we installed, right?
[root@zabbix ~]# rpm -q zabbix-server-mysql zabbix-server-mysql-3.2.4-2.el7.x86_64 [root@zabbix ~]#
Looks like it. And yum's log, /var/log/yum.log file think so too:
Mar 07 14:30:20 Installed: zabbix-web-mysql-3.2.4-2.el7.noarch Mar 07 14:30:21 Installed: zabbix-web-3.2.4-2.el7.noarch Mar 07 14:30:22 Installed: zabbix-server-mysql-3.2.4-2.el7.x86_64
This really does not make sense. Let me look again at the contents of the installed package, not at the rpm:

It turns out (kudos to irc user TrevorH for pointing that out) that yum is configured not to install docs
[root@zabbix ~]# grep -ir tsflags /etc/yum.* /etc/yum.conf:tsflags=nodocs [root@zabbix ~]#
Let's comment it out then and try again

Success at last!
I think that is enough for one article. If you expect this to have any closure or redeeming message, I have news for you sunshine. Just hope that the next zabbix article will talk about actually getting it installed and configured and running. But, I make no guarantees.
