Use yum to test Zabbix 2.4 On CentOS 7 or RHEL 7

Use yum to test Zabbix 2.4 On CentOS 7 or RHEL 7

Steps for lite version:
1. Add Source
Yum-y install epel-release
Vi/etc/yum. repos. d/zabbix. repo
[Zabbix]
Name = Zabbix
Base url = http://repo.zabbix.com/zabbix/2.4/rhel/7/x86_64/
Gpgcheck = 1
Gpgkey = http://repo.zabbix.com/zabbix-official-repo.key

2. Installation Package
Yum-y install zabbix-server-mysql zabbix-agent zabbix-web-mysql mariadb-server httpd php

3. Prepare the database
3.1 start the Database Service and automatically start it at startup
Systemctl start mariadb
Systemctl enable mariadb

3.2 reinforce Database
Mysql_secure_installation
Set the root password of the database. The default value is "yes" for all other options.
3.3 create a zabbix database and add accounts and permissions
Mysql-u root-p # log on to the database as the root user
Create database zabbix; # CREATE a dedicated zabbix Library
Grant all privileges on zabbix. * TO zabbix @ localhost identified by 'zabbix' # create a dedicated database administrator account zabbix with the password zabbix,
At the same time, the zabbix account is granted all permissions on all tables in the zabbix database.
Flush privileges; # valid Permissions
Exit; Save and exit the database
3.4 import the zabbix database configuration table
Mysql-u root-p zabbix </usr/share/doc/zabbix-server-mysql-*/create/schema. SQL

Mysql-u root-p zabbix </usr/share/doc/zabbix-server-mysql-*/create/images. SQL
Mysql-u root-p zabbix </usr/share/doc/zabbix-server-mysql-*/create/data. SQL

4. Configure the Web Server
Optimize PHP. The last time zone must be changed.
Sed-I's/^ max_execution_time. */max_execution_time = 600/'/etc/php. ini
Sed-I's/^ max_input_time. */max_input_time = 600/'/etc/php. ini
Sed-I's/^ memory_limit. */memory_limit = 256 M/'/etc/php. ini
Sed-I's/^ post_max_size. */post_max_size = 32 M/'/etc/php. ini
Sed-I's/^ upload_max_filesize. */upload_max_filesize = 16 M/'/etc/php. ini
Sed-I "s/^ \; date. timezone. */date. timezone = \ 'Asia \/Shanghai \ '/"/etc/php. ini
Reinforce apache
Vim/etc/httpd/conf. d/zabbix. conf
#
# Zabbix monitoring system php web frontend
#
Alias/zabbix/usr/share/zabbix
<Directory "/usr/share/zabbix">
Options FollowSymLinks
AllowOverride None
Require all granted
</Directory>
<Directory "/usr/share/zabbix/conf">
Require all denied
</Directory>
<Directory "/usr/share/zabbix/include">
Require all denied
</Directory>
Enable Firewall Rules, start services, and check logon status
Firewall-cmd -- zone = public -- add-service = http-permanent
Systemctl start httpd

Systemctl enable httpd

5. Configure zabbix
Configure zabbix
Sed-I's/^ # DBPassword =. */DBPassword = zabbix/'/etc/zabbix/zabbix_server.conf
Parameter Optimization
Sed-I's/^ # CacheSize =. */CacheSize = 32 M/'/etc/zabbix/zabbix_server.conf
Sed-I's/^ # StartPingers =. */StartPingers = 5/'/etc/zabbix/zabbix_server.conf
Configure selinux
Setsebool-P httpd_can_connect_zabbix = true
Start the service
Systemctl enable zabbix-server
Systemctl start zabbix-server
# A bug will cause startup failure, segfault at 18 ip Route 7fbf1295dc00 sp route 7ffff5527ec8 error 4 in libpthread-2.17.so [7fbf12954000 + 16000]
You can downgrade gnutls to 3.1.20 or yum-y update to restart the service.
For more information, please move to the https://support.zabbix.com/browse/ZBX-7790
Web login http://zabbix.it.lab/zabbix, complete Initialization Configuration
Default logon username admin and password zabbix

6. Add a monitoring host
Yum-y install epel-release
Yum-y install zabbix22-agent
Modify configuration file
Sed-I's/^ Server = 127.0.0.1/Server = zabbix. it. lab/G'/etc/zabbix/zabbix_agentd.conf
Enable Service
Systemctl enable zabbix-agent
Systemctl start zabbix-agent

This is a pitfall, server not running

The disabling of selinux and the firewall is not solved, and selinux is basically mentioned when a ladder is searched.
Check the log/var/log/zabbix/zabbix_server.log carefully.
Connection to database 'zabbix' failed: [1045] Access denied for user 'zabbix' @ 'localhost' (using password: NO)
Mysql-u zabbix-p zabbix logon is successful, and the problem is undoubtedly caused by zabbix configuration.
Grep DBPassword/etc/zabbix/zabbix_server.conf
# For SQLite3 path to database file must be provided. DBUser and DBPassword are ignored.
### Option: DBPassword
# DBPassword =
The password is not matched here, and it is also dumb.

Learning Linux has almost become a kind of practice for myself. Calm down, don't worry, don't worry, don't pursue perfect solution take every command seriously, every letter is case-sensitive; first solve the current requirements, Don't blindly follow interest. These will be a lifetime of wealth.
