Installation on a new server :
First Server steps:
yum update -y
yum upgrade -y
yum install wget epel-release php56-mbstring yum-utils
yum-config-manager --enable rhui-REGION-rhel-server-extras rhui-REGION-rhel-server-optiona

and then :
yum install php-mbstring php-bcmath



# add this to .bashrc :
vi .bashrc

HISTTIMEFORMAT="%d/%m/%y %T "

# disable selinux:
vi /etc/selinux/config
change SELINUX=enforcing to SELINUX=disabled

#then run on CLI and run:
setenforce 0


# installing Zabbix server:
rpm -ivh http://repo.zabbix.com/zabbix/3.2/rh...el7.noarch.rpm

yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent zabbix-java-gateway mariadb-server


#start MariaDb:
systemctl enable mariadb
systemctl start mariadb


#make SQL secure (optional)

mysql_secure_installation


#Set the below parameters in the PHP config file (/etc/php.ini )


vi /etc/php.ini

change this values:
[CODE]max_execution_time = 600
max_input_time = 600
memory_limit = 256M
post_max_size = 32M
upload_max_filesize = 16M
date.timezone = Asia/Kolkata (your machine timezone)


#firewall settings:
firewall-cmd --permanent --add-port=10050/tcp
firewall-cmd --permanent --add-port=10051/tcp
firewall-cmd --permanent --add-port=80/tcp
firewall-cmd --reload
systemctl restart firewalld

# Now start services:

systemctl start zabbix-server
systemctl enable zabbix-server
systemctl enable httpd
systemctl restart httpd

# to avoid future DB issues (DB growing too fast)we will set innodb per table:


#Backup mysql:

mysqldump --all-databases -p > mysqlall.sql


#Shutdown mysql

service mariadb stop


# Add the following lines to /etc/my.cnf.d/server.conf

[mysqld]
innodb_file_per_table
innodb_flush_method=O_DIRECT
innodb_log_file_size=1G
innodb_buffer_pool_size=4G
innodb_data_file_path=ibdata1:10M:autoextend


Whatever your set for innodb_buffer_pool_size, make sure innodb_log_file_size is 25% of innodb_buffer_pool_size.


#Delete ibdata1, ib_logfile0 and ib_logfile1 (see update below before deleting!)

rm -rf /var/lib/mysql/ib*


#Restart mysql

service mariadb restart


#now we will set zabbix DB:


mysql -p
>> create database zabbixdb;
>> grant all privileges on zabbixdb.* to zabbix@localhost identified by 'PASSWORD';
>> flush privileges;
>>exit


#building zabbixdb:
cd /usr/share/doc/zabbix-server-mysql-3.2.4/
gunzip create.sql.gz
mysql -u root -p zabbixdb < create.sql


# now we will set zabbix server DB Parameters at zabbix_server.conf:


vi /etc/zabbix/zabbix_server.conf
DBHost=localhost
DBName=zabbixdb
DBUser=zabbix
DBPassword=XXXXXXX



#restart server:

systemctl restart Zabbix-server


#enabling Zabbix agent and installing Zabbix_get:

systemctl enable zabbix-agent
systemctl start zabbix-agent

wget http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-get-3.2.4-2.el7.x86_64.rpm

rpm -Uvh zabbix-get-3.2.4-2.el7.x86_64.rpm


after this been done go to http://127.0.0.1/zabbix
it will reload zabbix first settings page just follow its orders and make sure
all DB settings there is correct and all packages is marked as green OK.

Login with :
user: admin
password: zabbix

Good Luck!

yum install wget epel-release php56-mbstring yum-utils
yum-config-manager --enable rhui-REGION-rhel-server-extras rhui-REGION-rhel-server-optiona

and then :
yum install php-mbstring php-bcmath

I do not recommend installing both php56-mbstring and php-mbstring.
Beginners are obstacles by installing different versions of packages at the same time, so please be careful.

rhui-REGION-rhel-server-extras and rhui-REGION-rhel-server-optional are for RHEL 7 on EC2.
These are not for CentOS 7.

The following package is unnecessary if it is configured with the standard package of CentOS 7.

php56-mbstring yum-utils rhui-REGION-rhel-server-extras rhui-REGION-rhel-server-optional

Also, if you install zabbix-web-mysql using the yum command, the following package will be installed automatically.

php-mbstring php-bcmath

mysql -p
>> create database zabbixdb;
>> grant all privileges on zabbixdb.* to zabbix@localhost identified by 'PASSWORD';
>> flush privileges;
>>exit

In the manual, it is described as follows.

shell> mysql -uroot -p<root_password>
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> grant all privileges on zabbix.* to zabbix@localhost identified by '<password>';
mysql> quit;

Please pay attention to the character set to use.
If you do not specify a character code at create database, specify it in /etc/my.cnf.d/server.cnf.

Manual:

https://www.zabbix.com/documentation/3.2/manual/installation/install_from_packages/server_installation_with_mysql

#building zabbixdb:
cd /usr/share/doc/zabbix-server-mysql-3.2.4/
gunzip create.sql.gz
mysql -u root -p zabbixdb < create.sql

You can simplify the procedure as follows.

# zcat /usr/share/doc/zabbix-server-mysql-3.2.4/create.sql.gz | mysql -uzabbix -p zabbixdb

wget http://repo.zabbix.com/zabbix/3.2/rh...el7.x86_64.rpm

rpm -Uvh zabbix-get-3.2.4-2.el7.x86_64.rpm

If you can use the yum command, just install the zabbix_get command by running the following command:

# yum install zabbix-get

I encourage you to capitalize the first letter of the account when logging in to the web frontend. (admin -> Admin)
It depends on the character set and collation of the DBMS environment to be used.

Hi,

I'm trying to install Zabbix 3.2 on CentOS 7.3, but I get some keys errors.
I think that there are any kind of differences with the packages on the repository.

I didi it on some servers and I got the same error...

I translate from spanish, for you:

---
Total size: 42 M
Instaled sizw: 156 M
Is this ok [y/d/N]: y
Downloading packages:
warning:/var/cache/yum/x86_64/7/zabbix/packages/zabbix-agent-3.2.7-1.el7.x86_64.rpm: EncabezadoV4 RSA/SHA512 Signature, Key ID a14fe591: NOKEY
Getting key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591


The GPG keys listed for "Zabbix Official Repository - x86_64" repository, are installed, but aren't correct with this package.
Check if the keys URLs for this repository are correct configured.


Wrong package: zabbix-agent-3.2.7-1.el7.x86_64
GPG keys are configured as: file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591
---

I think are there an error on Zabbix site, but I apreciate some helps for install it.

Thank, you

After reinstalling the zabbix-release package, try clearing the cache of yum before trying.

ex.

# yum remove zabbix-release
# yum install http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm
# yum clean all
# yum install zabbix-agent

[balozabbix]

Excelent!!!

Thank you very much!!!

[mw72]

more basic guide

@ Atushi

Would you be able to write a more basic step by step guide

combining the Zabbix "Installation instructions"

with your comments and filling in the blanks for the non Linux users like myself ?

Thanks

Hi mw72,
If you have disabled SELinux, you can install it as follows.
However, since version 3.2 has been discontinued, it is the procedure for version 3.4.

# yum update
# yum install http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-2.el7.noarch.rpm
# yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent
# yum install mariadb-server
# vi /etc/my.cnf.d/server.cnf
-----
[mysqld]
character-set-server = utf8
collation-server     = utf8_bin
