本篇文章介绍zabbix监控，监控是对我们操作系统进行不间断的监控，这是软件生命周期非常重要的一环，可以做到事前告警，事后根据监控内容排查问题（金丝雀，监控重要指标），有问题的时候，运维需要管理运维债务（在软件开发过程中积累的一些技术债务）

监控内容

我们需要监控硬件（磁盘df -h，内存free，磁盘IO，负载CPU，网络），软件服务（端口、进程、状态），业务层面（监控业务数据，订单量，注册用户，充值用户），只要是有值，zabbix都能监控，核心功能就是自定义监控。

监控工具

zabbix 硬件 服务状态 自定义监控

Nagions 网络产品 交换机 路由器 中型大型公司使用

Cacti 流量

Open-Falcon 小米公司自研

prometheus 监控kubernetes docker，比zabbix更好

监控宝等等

Zabbix安装

服务端：10.0.0.71（配置与监控数量有关，企业中一般是8G内存，4核或6核）

客户端：10.0.0.7，10.0.0.8

系统版本为CentOS7.9

1、配置yum源

rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpmyum clean all

2、安装zabbix服务

yum -y install zabbix-server-mysql zabbix-agent

3、安装scl源，更好兼容已经安装的软件包，避免把系统搞烂

yum -y install centos-release-scl

4、开启前端的仓库

[root@Zabbix ~]# cat /etc/yum.repos.d/zabbix.repo[zabbix]name=Zabbix Official Repository - $basearchbaseurl=http://repo.zabbix.com/zabbix/5.0/rhel/7/$basearch/enabled=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591[zabbix-frontend]name=Zabbix Official Repository frontend - $basearchbaseurl=http://repo.zabbix.com/zabbix/5.0/rhel/7/$basearch/frontendenabled=1#开这里gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591[zabbix-debuginfo]name=Zabbix Official Repository debuginfo - $basearchbaseurl=http://repo.zabbix.com/zabbix/5.0/rhel/7/$basearch/debuginfo/enabled=0gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591gpgcheck=1[zabbix-non-supported]name=Zabbix Official Repository non-supported - $basearchbaseurl=http://repo.zabbix.com/non-supported/rhel/7/$basearch/enabled=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIXgpgcheck=1

5、安装php和apache前端

 yum -y install zabbix-web-mysql-scl zabbix-apache-conf-scl

6、安装mariadb

yum -y install mariadb-serversystemctl start mariadbsystemctl enable mariadb

7、配置zabbix数据库

[root@Zabbix ~]# mysql -urootWelcome to the MariaDB monitor.Commands end with ; or \g.Your MariaDB connection id is 2Server version: 5.5.68-MariaDB MariaDB ServerCopyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.MariaDB [(none)]> create database zabbix character set utf8 collate utf8_bin;Query OK, 1 row affected (0.00 sec)MariaDB [(none)]> create user zabbix@localhost identified by 'zabbix';Query OK, 0 rows affected (0.00 sec)MariaDB [(none)]> grant all privileges on zabbix.* to zabbix@localhost;Query OK, 0 rows affected (0.00 sec)MariaDB [(none)]> set global log_bin_trust_function_creators = 1;Query OK, 0 rows affected (0.00 sec)MariaDB [(none)]> quit;Bye

8、导入数据库，初始化数据

[root@Zabbix ~]# zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbixEnter password: zabbix

可以进去检查一下

[root@Zabbix ~]# mysql -urootWelcome to the MariaDB monitor.Commands end with ; or \g.Your MariaDB connection id is 5Server version: 5.5.68-MariaDB MariaDB ServerCopyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.Type 'help;' or '\h' for help.

9、再次配置数据库

[root@Zabbix ~]# mysql -urootWelcome to the MariaDB monitor.Commands end with ; or \g.Your MariaDB connection id is 8Server version: 5.5.68-MariaDB MariaDB ServerCopyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.MariaDB [(none)]> set global log_bin_trust_function_creators = 0;Query OK, 0 rows affected (0.00 sec)MariaDB [(none)]> quitBye

10、修改zabbix连接数据库的信息

[root@Zabbix ~]# egrep ^DB /etc/zabbix/zabbix_server.confDBName=zabbixDBUser=zabbixDBPassword=zabbix#取消注释

11、修改时区

[root@Zabbix ~]# tail -1 /etc/opt/rh/rh-php72/php-fpm.d/zabbix.confphp_value[date.timezone] = Asia/Shanghai

12、启动zabbix进程

[root@Zabbix ~]# systemctl restart zabbix-server zabbix-agent httpd rh-php72-php-fpm[root@Zabbix ~]# systemctl enable zabbix-server zabbix-agent httpd rh-php72-php-fpm

13、浏览器访问安装

14、修改语言为中文

15、修改乱码

上传windows字体到zabbix中

[root@Zabbix ~]# cd /usr/share/fonts/dejavu[root@Zabbix dejavu]# lltotal 5288-rw-r--r-- 1 root root 611212 Feb 272011 DejaVuSans-BoldOblique.ttf-rw-r--r-- 1 root root 672300 Feb 272011 DejaVuSans-Bold.ttf-rw-r--r-- 1 root root 580168 Feb 272011 DejaVuSansCondensed-BoldOblique.ttf-rw-r--r-- 1 root root 631992 Feb 272011 DejaVuSansCondensed-Bold.ttf-rw-r--r-- 1 root root 576004 Feb 272011 DejaVuSansCondensed-Oblique.ttf-rw-r--r-- 1 root root 643852 Feb 272011 DejaVuSansCondensed.ttf-rw-r--r-- 1 root root 345204 Feb 272011 DejaVuSans-ExtraLight.ttf-rw-r--r-- 1 root root 611556 Feb 272011 DejaVuSans-Oblique.ttf-rw-r--r-- 1 root root 720012 Feb 272011 DejaVuSans.ttf[root@Zabbix dejavu]# rz -Erz waiting to receive.[root@Zabbix dejavu]# mv DejaVuSans.ttf DejaVuSans.ttf.bak[root@Zabbix dejavu]# mv simhei.ttf DejaVuSans.ttf

Zabbix添加监控服务器

1、安装zabbix-agent客户端，准备一台服务器10.0.0.7

#配置yum仓库rpm -ivh https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/x86_64/zabbix-agent-5.0.34-1.el7.x86_64.rpm#解决软件冲突yum -y install centos-release-scl#安装客户端agentyum -y install zabbix-agent

2、配置zabbix客户端服务器信息，启动服务端

[root@Web01 yum.repos.d]# cat /etc/zabbix/zabbix_agentd.confServer=172.16.1.71[root@Web01 yum.repos.d]# systemctl start zabbix-agent

3、zabbix监控web01

拆分数据库

1、准备一台数据库服务器10.0.0.51安装mariadb

[root@DB01 ~]# yum -y install mariadb-server[root@DB01 ~]# systemctl start mariadb[root@DB01 ~]# systemctl enable mariadb[root@DB01 ~]# mysqlWelcome to the MariaDB monitor.Commands end with ; or \g.Your MariaDB connection id is 2Server version: 5.5.68-MariaDB MariaDB ServerCopyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.MariaDB [(none)]> create database zabbix character set utf8 collate utf8_bin;Query OK, 1 row affected (0.00 sec)MariaDB [(none)]> create user 'zabbix'@'%' identified by 'zabbix';Query OK, 0 rows affected (0.00 sec)MariaDB [(none)]> grant all privileges on zabbix.* to 'zabbix'@'%';Query OK, 0 rows affected (0.00 sec)MariaDB [(none)]> quitBye

2、导出zabbix服务器zabbix数据库，导入到新的数据库

[root@Zabbix ~]# mysqldump -uroot -B zabbix > zabbix.sql[root@Zabbix ~]# cat zabbix.sql |mysql -h 172.16.1.51 -uzabbix -pzabbix zabbix

3、配置WEB连接数据库信息并重启服务

[root@Zabbix ~]# cat /etc/zabbix/web/zabbix.conf.php<?php// Zabbix GUI configuration file.$DB['TYPE']= 'MYSQL';$DB['SERVER']= '172.16.1.51';$DB['PORT']= '3306';$DB['DATABASE']= 'zabbix';$DB['USER']= 'zabbix';$DB['PASSWORD']= 'zabbix';......[root@Zabbix ~]# grep ^DB /etc/zabbix/zabbix_server.conf DBHost=172.16.1.51DBName=zabbixDBUser=zabbixDBPassword=zabbix[root@Zabbix ~]# systemctl restart zabbix-server httpd
