Centos7.6环境部署zabbix

部署环境:

Centos7.6

Zabbix 4.4.0

部署前环境准备或清理:

关闭SeLinux

vi /etc/selinux/config
SELINUX=disabled

yum remove mariadb
rm -rf /etc/my.cnf
rm -rf /var/lib/mysql/

一. zabbix监控主机的安装
1、安装apache
yum install -y httpd
httpd服务开机进行自启
systemctl enable httpd
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.

启动httpd服务
systemctl restart httpd

2、安装mysql
因为7版本mysql要收费，所以我们安装mariadb
yum install -y mariadb mariadb-server

开机自启动
systemctl enable mariadb

运行服务
systemctl restart mariadb
systemctl status mariadb
mysql_secure_installation

MariaDB
vi /etc/my.cnf.d/server.cnf
注释掉skip-networking选项来开启远程访问

查看Mariadb是否安装成功,输入命令:
mysql

3、安装php环境
yum install -y php php-mysql

4、安装zabbix
(1)下载包
cd /opt/software/
wget http://repo.zabbix.com/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.el7.noarch.rpm
rpm -ivh zabbix-release-4.4-1.el7.noarch.rpm
(2)安装zabbix的包
yum install -y zabbix-agent zabbix-server-mysql zabbix-get zabbix-web zabbix-web-mysql zabbix-sender

4、创建一个zabbix库并设置为utf8的字符编码格式

mysql -uroot -p
delete from mysql.user where user='';
create database zabbix character set utf8 collate utf8_bin;
show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| test               |
| zabbix             |
+--------------------+

创建账户并且授权设置密码
grant all privileges on *.* to 'root'@'localhost' identified by 'RootUserPasswd' with grant option;
grant all privileges on *.* to 'zabbix'@'localhost' identified by 'zabbixUserPasswd' with grant option;
grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbixUserPasswd';
grant all privileges on zabbix.* to 'zabbix'@'%' identified by 'zabbixUserPasswd' with grant option;
flush privileges;

5、导入表
切换到此目录下
cd /usr/share/doc/zabbix-server-mysql-4.4.0/
ls
AUTHORS  ChangeLog  COPYING  create.sql.gz  NEWS  README
ls
AUTHORS  ChangeLog  COPYING  create.sql  NEWS  README

对表进行导入
mysql
use zabbix;
source create.sql

6、配置zabbix server配置文件
配置文件目录
cd /etc/zabbix

zabbix_server.conf关键配置发下:
vim /etc/zabbix/zabbix_server.conf
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix
DBSocket=/tmp/mysql.sock

运行zabbix-server服务
开机自启zabbix-server服务
systemctl status zabbix-server
systemctl restart zabbix-server

7、配置php时区
vi /etc/httpd/conf.d/zabbix.conf
php_value date.timezone Asia/Shanghai
保存退出

systemctl restart httpd

8、登陆zabbix网址设置
http://localhost/zabbix/setup.php

登陆账户是Admin
密码是zabbix

二. zabbix的安装
有外网
rpm -ivh http://repo.zabbix.com/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.el7.noarch.rpm
yum install -y zabbix-agent

没有外网
wget http://repo.zabbix.com/zabbix/4.4/rhel/7/x86_64/zabbix-agent-4.4.0-1.el7.x86_64.rpm
rpm -ivh zabbix-agent-4.4.0-1.el7.x86_64.rpm

mv /etc/zabbix/zabbix_agentd.conf /etc/zabbix/zabbix_agentd.bak
vim /etc/zabbix/zabbix_agentd.conf
Server=服务器本地Ip,127.0.0.1
ServerActive=服务器本地Ip,127.0.0.1
Hostname=Zabbix server
PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=0
Include=/etc/zabbix/zabbix_agentd.d/*.conf
UnsafeUserParameters=1
AllowRoot=1
DebugLevel=3

zabbix服务状态或重启
systemctl status zabbix-agent
systemctl restart zabbix-agent

问题集:
1.解决中文乱码无法显示的问题
ftp上传simsun.ttf(来自C:\Windows\Fonts\)文件夹
cp simsun.ttf zabbix-web:/usr/share/zabbix/assets/fonts/simsun.ttf
vim /usr/share/zabbix/include/defines.inc.php
define('ZBX_GRAPH_FONT_NAME', 'DejaVuSans');
define('ZBX_FONT_NAME', 'DejaVuSans');
改
define('ZBX_GRAPH_FONT_NAME', 'simsun');
define('ZBX_FONT_NAME', 'simsun');

2. Zabbix discoverer processes more than 75% busy
解决办法:
修改zabbix_server.conf中discovery进程数量；
#StartDiscoverers可根据设置的discovery任务数量设置，范围是0~250
sed -i 's|# StartDiscoverers=1|StartDiscoverers=2|g' /etc/zabbix/zabbix_server.conf
即:
将#StartDiscoverers=1 改为: StartDiscoverers=10
