zabbix搭建

1、在zabbix服务端配置zabbix源（实验环境为centos7，如果使用centos6将连接地址中的7修改为6即可）

#m01 web01 web02
rpm -ivh https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/3.0/rhel/7/x86_64/zabbix-release-3.0-1.el7.noarch.rpm

2、安装相应软件

#m01
yum install zabbix-server-mysql zabbix-web-mysql httpd php -y
yum -y install mariadb-server
yum install -y zabbix-agent zabbix-get

3、配置数据库

#配置 mariadb
mysql
create database zabbix character set utf8 collate utf8_bin;
grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix';

#实际操作命令
MariaDB [(none)]> create database zabbix character set utf8 collate utf8_bin;
Query OK, 1 row affected (0.00 sec)

MariaDB [(none)]> grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix';
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> Bye

MariaDB [(none)]> show tables from zabbix;
Empty set (0.00 sec)

4、同步数据库

[root@m01 ~]# zcat /usr/share/doc/zabbix-server-mysql-3.0.19/create.sql.gz|mysql zabbix

5、启动zabbix、数据库、apache

[root@m01 ~]# systemctl start zabbix-server.service httpd.service mariadb

修改zabbix的登录密码
sed -i '115a DBPassword=zabbix' /etc/zabbix/zabbix_server.conf
# 修改apache-php配置
sed -i.ori '18a php_value date.timezone Asia/Shanghai' /etc/httpd/conf.d/zabbix.conf

[root@m01 ~]# grep -i ^DBpas /etc/zabbix/zabbix_server.conf
DBPassword=zabbix

6、客户端安装（客户端也需要添加zabbix源可以参考第一项）

#web01 web02
yum install -y zabbix-agent

zabbix yum源
repo.zabbix.com

mirrors.aliyun.com
https://mirrors.tuna.tsinghua.edu.cn

7、在服务端进行测试看客户端是否添加成功

[root@m01 ~]# zabbix_get -s 172.16.1.61 -p10050 -k agent.ping
1

8、修改zabbix的中文乱码

yum -y install wqy-microhei-fonts
cp /usr/share/fonts/wqy-microhei/wqy-microhei.ttc /usr/share/fonts/dejavu/DejaVuSans.ttf

监控项 item

web01 监控服务器登录的用户数量 >3

创建自定义监控项

1.命令测试命令
[root@web01 ~]# who|wc -l
2

2.写入到客户端的自定义文件中
自定义key(键值)
agent.ping

/etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf
/etc/zabbix/zabbix_agentd.d/user.conf
/etc/zabbix/zabbix_agentd.d/web.conf

用户自定义的键值
UserParameter=mysql.version,mysql -V
UserParameter=key,命令/脚本
UserParameter=key[*],命令/脚本 $1

UserParameter=login.user,who|wc -l

[root@web01 ~]# tail -1 /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf
UserParameter=login.user,who|wc -l
[root@web01 ~]# systemctl restart zabbix-agent.service

[root@m01 ~]# zabbix_get -s 172.16.1.7 -klogin.user
3

3.web页面的操作

监控项:
30秒1次 1个小时120次

历史数据保留时长（单位天)
趋势数据存储周期(单位天)
每小时取得一次数据

触发器-trigger

#监控nginx状态
nginx.conf
[root@web01 ~]# cat /etc/nginx/nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;

}

location = /50x.html {

}
location /nginx.status {
stub_status on;
access_log off;
allow 172.16.1.0/24;
deny all;
}
}
}

[root@web01 ~]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@web01 ~]#
[root@web01 ~]# systemctl restart nginx

[root@web01 ~]# curl 172.16.1.7/nginx.status
Active connections: 1
server accepts handled requests
5 5 5
Reading: 0 Writing: 1 Waiting: 0

#1.确认需求找出对应命令

[root@web01 ~]# curl 172.16.1.7/nginx.status
Active connections: 1
server accepts handled requests
1 1 1
Reading: 0 Writing: 1 Waiting: 0

[root@web01 ~]# curl -s 172.16.1.7/nginx.status |awk 'NR==1{print $NF}'
1
active curl -s 172.16.1.7/nginx.status |awk 'NR==1{print $NF}'
accept curl -s 172.16.1.7/nginx.status |awk 'NR==3{print $1}'
handle curl -s 172.16.1.7/nginx.status |awk 'NR==3{print $2}'
request curl -s 172.16.1.7/nginx.status |awk 'NR==3{print $3}'
read curl -s 172.16.1.7/nginx.status |awk 'NR==4{print $2}'
write curl -s 172.16.1.7/nginx.status |awk 'NR==4{print $4}'
wait curl -s 172.16.1.7/nginx.status |awk 'NR==4{print $6}'

#2.把命令写入到用户自定义监控目录
UserParameter=active,curl -s 172.16.1.7/nginx.status |awk 'NR==1{print $NF}'
UserParameter=accept,curl -s 172.16.1.7/nginx.status |awk 'NR==3{print $1}'
UserParameter=handle,curl -s 172.16.1.7/nginx.status |awk 'NR==3{print $2}'
UserParameter=request,curl -s 172.16.1.7/nginx.status |awk 'NR==3{print $3}'
UserParameter=read,curl -s 172.16.1.7/nginx.status |awk 'NR==4{print $2}'
UserParameter=write,curl -s 172.16.1.7/nginx.status |awk 'NR==4{print $4}'
UserParameter=wait,curl -s 172.16.1.7/nginx.status |awk 'NR==4{print $6}'

#3.通过shell脚本完成
[root@web01 ~]# mkdir -p /server/scripts/
[root@web01 ~]# vim /server/scripts/ng-stat.sh

nginx.stat[*]

自动发现 zdfx auto discovery （被动模式）
服务端挨个询问客户端是否是新来的

自动注册 auto reg （主动模式）
新来的自动寻找服务端提交自己的信息让服务端把自己加入到 zabbix中
