Centos7.2 安装 zabbix server 3.4 及初始化工作

CentOS 前端之家
前端之家收集整理的这篇文章主要介绍了Centos7.2 安装 zabbix server 3.4 及初始化工作，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

Centos7.2 安装 zabbix server 3.4


一、安装 zabbix server 3.4

参考连接：

https://www.zabbix.com/download?zabbix=3.4&os_distribution=centos&os_version=7&db=MySQL

https://www.zabbix.com/documentation/3.4/zh/manual/installation/install_from_packages#from_distribution_packages


关闭防火墙

#systemctlstopfirewalld.service#关闭防火墙
#systemctldisablefirewalld.service#开机不启动防火墙

　

关闭selinux

#sed-i's/SELINUX=enforcing/SELINUX=disabled/'/etc/selinux/config#在/etc/selinux/config把SELNUX=enforcing换成SELINUX=disabled

#grepSELINUX=disabled/etc/selinux/config#过滤刚刚换的disabled
SELINUX=disabled
#setenforce0#清空selinux的配置


MysqL数据库的安装

tarxvfMysqL-5.7.20-1.el7.x86_64.rpm-bundle.tar
rpm-e--nodepsmariadb-libs
rpm-ivhMysqL-community-client-5.7.20-1.el7.x86_64
rpm-ivhMysqL-community-libs-5.7.20-1.el7.x86_64
rpm-ivhMysqL-community-server-5.7.20-1.el7.x86_64
rpm-ivhMysqL-community-common-5.7.20-1.el7.x86_64
rpm-ivhMysqL-community-libs-compat-5.7.20-1.el7.x86_64

systemctlstartMysqLd#修改密码

cat/var/log/MysqLd.log|greppasswordsystemctlenableMysqLd

alteruserroot@'localhost'identifiedby'';

Zabbix Server 3.4安装及配置

wget http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-2.el7.noarch.rpm

rpm -ivh zabbix-release-3.4-2.el7.noarch.rpm


安装163的yum源，zabbix必须的PHP两个所需模块bcmath和mbstring epel yum 源没有， 只有网易163源中有


wget http://mirrors.163.com/.help/CentOS7-Base-163.repo

# yum install zabbix-server-MysqL zabbix-web-MysqL zabbix-agent


# MysqL -uroot -p

# 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;


# zcat /usr/share/doc/zabbix-server-MysqL*/create.sql.gz | MysqL -uzabbix -D zabbix -p



配置zabbix数据库

# vi /etc/zabbix/zabbix_server.conf

DBHost=localhost

DBName=zabbix

DBUser=zabbix

DBPassword=password



# systemctl start zabbix-server zabbix-agent httpd

# systemctl enable zabbix-server zabbix-agent httpd


配置 PHP zabbix 前台


vim /etc/httpd/conf.d/zabbix.conf

# PHP_value date.timezone Europe/Riga

替换为：

PHP_value date.timezone Asia/Shanghai



配置 zabbix前台

Connect to your newly installed Zabbix frontend: http://server_ip_or_name/zabbix

Follow steps described in Zabbix documentation: Installing frontend



zabbix 帮助文档

https://www.zabbix.com/documentation/3.4/manual/quickstart/login



二、zabbix agent 安装


wget http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-2.el7.noarch.rpm

rpm -ivh zabbix-release-3.4-2.el7.noarch.rpm


yum install zabbix-agent

systemctl start zabbix-agent

systemctl enable zabbix-agent


客户端配置：

# cat /etc/zabbix/zabbix_agentd.conf | grep -v "^#"| grep -v '^$'

PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=0
Server=192.168.1.51
ServerActive=192.168.1.51:10051
HostnameItem=system.run[ifconfig|grep"inet"|grep-E-o"(2[0-4][0-9]|25[0-5]|1[0-9][0-9]|[1-9]?[0-9])(.(2[0-4][0-9]|25[0-5]|1[0-9][0-9]|[1-9]?[0-9])){3}"|grep"192.168.1"|head-1]
RefreshActiveChecks=120
Include=/etc/zabbix/zabbix_agentd.d/*.conf

关闭 housekeeper ，防止出现select itemid,min(clock) from history_uint group by itemid 语句 ，改语句执行非常的慢，对数据库的插入性能，系统的负载等有非常大影响


关闭方法：

Administration -> General -> Housekeeping.

关闭history ，trends表的清理策略
