Shulou(Shulou.com)06/02 Report--

Zabbix proxy can collect performance and availability data instead of zabbix server, then report the data to zabbix server, and to some extent share the pressure of zabbix server.

After proxy collects the data, it first caches the data locally, and then passes it to zabbix server after a certain period of time, so that the data is not lost due to any temporary communication problems on the server. This time is determined by the parameters ProxyLocalBuffer and ProxyOfflineBuffer in the proxy configuration file.

The zabbix proxy database must be separated from server, or the data will be corrupted.

The deployment environment is ready. Pay attention to the version of zabbix_server here. The version of proxy must correspond to the version of server.

System version: CentOS 7.5

Software version: zabbix_proxy 3.4

Download the yum feed:

Rpm-Uvh rpm-ivh http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-1.el7.noarch.rpm

Rpm-Uvh http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm

When you are finished, install proxy and mysql database directly with yum

Yum install-y zabbix-proxy-mysql # install zabbix-proxy

Yum install-y mysql-server # installation database

First start and log in to mysql to create our proxy database

Systemctl start mysqld.service # launch mysql

Systemctl enable mysqld.service # set boot up

Enter mysql:

Create database zabbix_proxy character set utf8 collate utf8_bin; # Building Library

Grant all privileges on zabbix_proxy.* to zabbix@localhost identified by 'newpassword'; # authorization

Import table structure

Zcat / usr/share/doc/zabbix-proxy-mysql-3.4.15/schema.sql.gz | mysql- u zabbix-p zabbix_proxy # Import table structure

Edit the configuration file for zabbix_proxy

Vim / etc/zabbix/zabbix_proxy.conf # modify the configuration file of zabbix-proxy

Basic parameter settings:

Address of Server=192.168.X.X # zabbix-server

Hostname=zabbix-proxy # Hostname

DBHost=localhost # database host

DBName=zabbix_proxy # Database name

DBUser=zabbix # Database user name

DBPassword=newpassword # database password

What is not configured in the configuration file is as follows:

# ProxyLocalBuffer=0

# time for data retention (in hours)

# ProxyOfflineBuffer=1

# how long do you want to keep the data if you can't connect to Server (in hours, default is 1 hour)

# DataSenderFrequency=1

# interval between sending data (default is 1 second)

# StartPollers=5

# number of threads started

# StartIPMIPollers=0

# number of threads starting IPMI

Start zabbix_proxy and set boot up

Systemctl start zabbix-proxy.service # launch zabbix-proxy

Systemctl enable zabbix-proxy.service # Boot start

After completing the above steps, you can log in to our web interface to configure zabbix_proxy

Create a proxy:

Set up the agent: the name here must be the same as the name of the agent in the configuration file, otherwise an error will be reported.

Created successfully, host detected:

Abnormal problem:

Mysql change password:

Log in to mysql5.7 for the first time to force password change

Grant all privileges on *. * to 'root'@'%' identified by' root'

Alter user 'root'@'localhost' identified by' root'

Password policy problem exception message:

ERROR 1819 (HY000): Your password does not satisfy the current policy requirements

First of all, you need to set the authentication strength level of the password. Set the global parameter of validate_password_policy to LOW.

Enter the setting statement "set global validate_password_policy=LOW;" to set the value.

The current password length is 8, so you don't need to modify it if you don't mind. Generally speaking, set the password to 6 digits and set the global parameter of validate_password_length to 6.

Enter the setting statement "set global validate_password_length=6;" to set the value.
