Hello,I'm new to Zabbix and Centos in general. I am trying to install zabbix 3.2 on a clean install of Centos 6.8. I have installed the repository by doing the command :
yum install http://repo.zabbix.com/zabbix/3.2/rhel/6/x86_64/zabbix-release-3.2-1.el6.noarch.rpm

My problem is this:

yum install zabbix-server-mysql zabbix-web-mysql

Output:
https://s22.postimg.org/ic8x7bxtt/wrong.jpg

It seems that I have some dependencies error but I just don't know what to do.....

This is the list of what I have installed:

yum install httpd
yum install gcc
yum install fping
yum install mysqld
yum -y install php php-mbstring php-pear
yum install epel-release
yum install unixODBC-devel unixODBC
yum install OpenIPMI
yum install libssh2
yum installlibcurl
yum install iksemel

I installed a couple more but I can't remember them of the top of my head. I basically installed all the dependencies that was printed out when I did the command:

rpm -qpR zabbix-web-mysql-3.2.1-1.el6.noarch.rpm
rpm -qpR zabbix-server-mysql-3.2.1-1.el6.x86_64.rpm
rpm -qpR zabbix-web-3.2.1-1.el6.noarch.rpm

I can install the zabbix-server-mysql-3.2.1-1.el6.x86_64.rpm package manually by grabbing the file with wget and then using rpm -Uvh zabbix-server-mysql-3.2.1-1.el6.x86_64.rpm

It will install the package, but if I try to do it for zabbix-web-3.2.1-1.el6.noarch.rpm it says that It requires zabbix-web-database ( I assume it is: zabbix-web-mysql-3.2.1-1.el6.noarch.rpm ) and when I try to install zabbix-web-mysql-3.2.1-1.el6.noarch.rpm it says that it requires zabbix-web as dependencies (I assume this is web-3.2.1-1.el6.noarch.rpm).

I just wish to be able to type # yum install zabbix-server-mysql zabbix-web-mysql and have no problems.

Sorry if this thread double posted,I meant to click preview but I clicked Submit new thread.

Thank you for your time,
Bumbaa

it seems like it want you to install zabbix first
and your installing zabbix-server-mysql zabbix-web-mysql

After installing the Zabbix repository of packages, did you clear the cache of yum?

ex.
# yum install http://repo.zabbix.com/zabbix/3.2/rhel/6/x86_64/zabbix-release-3.2-1.el6.noarch.rpm
# yum clean all
# yum install zabbix-server-mysql zabbix-web-mysql

And, Zabbix 3.2 requires PHP 5.4 or later.
Since the dependency by PHP to be used is different, it is not set dependencies zabbix-web package.
Please install the necessary extension module for PHP.
(bcmath, gd, ldap, mbstring, xml, mysql, etc.)

I just wanted to point out that the zabbix-server-* and zabbix-web-* packages aren't in the repo that you installed, as they are considered "deprecated" in CentOS 6. If you look carefully at the output you provided, you can see that it's actually trying to install the 1.8.22-1.el6 version, which is most likely coming from the EPEL repo, not the zabbix repo.

It seems that Centos 6.8 comes with PHP5.3.3 Default, I updated it too PHP 5.4 and installed all the required dependencies and I was still getting that error. I saw that it was trying to download zabbix from the epel repository so I went to check the /etc/yum.repos.d/zabbix.repo and it turns out it wasn't enabled. I enabled it and it successfully downloaded everything.

Now when I do service zabbix-server start it will turn on for a fraction of a second and then turn back off. I check the zabbix-server log and it says Error 13 do not have permission to set parameters. I don't have the exact error log because it is at my work and I haven't written down exactly what it said. From what I gathered,I think it is a permission error.

But if I follow the instruction given at this page:
https://www.zabbix.com/documentation/3.2/manual/installation/install_from_packages/server_installation_with_mysql

It seems that I have the command correct. I am a bit confused by the meaning of deprecated, does it mean that it isn't able to install on Centos 6.8, that it is unsafe to install, unsupported?

I can't install zabbix 3.2 on centos 6.8?

Thanks.

If you have enabled SELinux, you need to change the setting.

Do not output a log, such as the following?

25766:20160404:163515.911 cannot set resource limit: [13] Permission denied

Based on the output log in /var/log/audit/audit.log, please set the SELinux policy.

In the other, you also need the following settings.

# setsebool -P httpd_can_network_connect on
# setsebool -P zabbix_can_network on

I think that it is possible to install the Zabbix 3.2.1 in CentOS 6.
But, it is not recommended.
ex. It will not be able to use the SMTP authentication.

Atushi answered that question in the post above. You need to enable the deprecated repo:

# yum --enablerepo=zabbix-deprecated install zabbix-server-mysql
# yum --enablerepo=zabbix-deprecated install zabbix-web-mysql

Presumably, zabbix on CentOS 6 is deprecated because CentOS 6's days are numbered, and they would rather focus their attention on supporting zabbix for CentOS 7. I don't particularly agree with this, however, given that CentOS 6 OS is going to be receiving maintenance updates until November 2020, which means there will probably still be many organizations running 6 for the foreseeable future.

I want to thank you both for expanding my knowledge on what deprecated means and how to install Zabbix 3.2 on Centos 6.8.I managed to get the server running, but some reason I was not able to connect to it. Something was blocking my connection to the server, I just said "screw it" and went with Centos 7 and the installation was very easy.

But now I have a different problems and it is related to the emailing alert service, I followed a guide on how to create a smtp server for centos 7 and I am using dovecot for authentification but I still get this error message when zabbix tries to send an email:

NOQUEUE: reject: RCPT from localhost[::1]: 554 5.7.1 <bob@random.ca>: Relay access denied; from=<localhost@test.com> to=<bob@random> proto=SMTP helo=<localhost>

I saw this thread:

Seems like it is related to the sourceIP? I have trouble understanding him.

I'm confused on what to do next.

Thank you very much,

Not positive, but you might want to add "random" and/or "random.ca" to the relay_domains section perhaps?

It seems that the installed version of mysql is not the CentOS 6 standard version.
If you want to run in an environment different from the standard version,
try rebuilding the package according to that environment.

The package version of CentOS 6 standard mysql-libs is as follows.
/usr/lib64/mysql/libmysqlclient.so.16
/usr/lib64/mysql/libmysqlclient.so.16.0.0
/usr/lib64/mysql/libmysqlclient_r.so.16
/usr/lib64/mysql/libmysqlclient_r.so.16.0.0

The version you are installing seems to be a newer version.
