Installation of Zabbix in Centos 7

scottalanmiller

Whether I have check the /etc/sudoers or change the permission of the folder of me to install the zabbix?

I know that you are in the sudoers with full root access. It was verified.

Lakshmana

Error I am facing here is given below as shown

[lakshmana@dny-lnx-zabbix home]$ yum install epel-release
Loaded plugins: fastestmirror
You need to be root to perform this command.

Why this comes?

scottalanmiller

You are missing the sudo before the command.

scottalanmiller

The EPEL is already installed as part of a base install, but no harm in doing it twice. But the command would be:

sudo yum install epel-release

Lakshmana

I have started my iinstallation by the other command

Configure the ZabbixZone package repository and GPG key using command:

rpm --import http://repo.zabbix.com/RPM-GPG-KEY-ZABBIX

rpm -Uv http://repo.zabbix.com/zabbix/2.4/rhel/7/x86_64/zabbix-release-2.4-1.el7.noarch.rpm

scottalanmiller

Don't forget the sudo

Lakshmana

Then the installtion of the Zabbix agent is done by the following command

Now, Install Zabbix server and agent using command:

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

which requires internet to download the package of 223 MB.

scottalanmiller

That is pretty small, it should be pretty fast.

Lakshmana

In order to update the time zone go to the file given below
Edit file /etc/httpd/conf.d/zabbix:

vi /etc/httpd/conf.d/zabbix.conf

@Lakshmana said:

Why are you changing the timezone? Is that part of a normal installation?

Lakshmana

No,If needed means we can change

Lakshmana

After the update of the time zone needs to update it by the following command

Restart the httpd

systemctl restart httpd
After the MySQL needs to configured here.If needed we need to install in the server

scottalanmiller

Don't forget a space after all punctuation.

Maria DB installation issue, I am facing in this is given below
[lakshmana@dny-lnx-zabbix ~]$ mysql_secure_installation
/usr/bin/mysql_secure_installation: line 379: find_mysql_client: command not found

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
Enter current password for root (enter for none):
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
Enter current password for root (enter for none):

scottalanmiller

I think that you forgot the step to start the server.

Lakshmana

Yes, I have started the MariaDB by the following command given below

sudo systemctl start mariadb
sudo systemctl enable mariadb

scottalanmiller

Use ps to see if it is running.

Lakshmana

Yes,the MySQL is working

[lakshmana@dny-lnx-zabbix ~]$ ps -ef | grep mysql
root 27635 27481 0 13:14 pts/4 00:00:00 sudo mysql_secure_installation

Then I have Set MySQL root password

By default, MySQL root password is empty. So, to prevent unauthorized access to MySQL, let us set root user password. Enter the following command to setup mysql root user password:

mysql_secure_installation
/usr/bin/mysql_secure_installation: line 379: find_mysql_client: command not found

In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] y ## Enter Y and press Enter
New password: ## Enter new password
Re-enter new password: ## Enter password again
Password updated successfully!
Reloading privilege tables..
... Success!

By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y ## Enter Y and press Enter
... Success!

Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y ## Enter Y and press Enter
... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y ## Enter Y and press Enter

Dropping test database...
... Success!
Removing privileges on test database...
... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y ## Enter Y and press Enter
... Success!

Cleaning up...

All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!
