2019.11.2 Zabbix agent端监控及自定义监控项配置

Posted 2020-11-30 990624lty-jhc

一、Linux-agent端的操作：

vim /etc/hostname

HOSTNAME=agent.zabbix.com

hoastname agent.zabbix.com

bash

cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.200.111 server.zabbix.com
192.168.200.112 agent.zabbix.com
192.168.200.110 windows10

iptables -F

systemctl stop firewalld

setenforce 0

ping server.zabbix.com -c 4

ping www.baidu.com

1、源码安装zabbix

yum -y install gcc gcc-c++ make

yum -y install libxml2-devel libcurl-devel pcre-devel ntpdate

ntpdate s1a.time.edu.cn

将zabbix-3.4.11.tar.gz 这个包上传并解压

tar xf zabbix-3.4.11.tar.gz -C /usr/src/
cd /usr/src/zabbix-3.4.11/
./configure --prefix=/usr/local/zabbix --enable-agent --with-net-snmp --with-libcurl --with-libxml2 && make-j2 && make install

cp misc/init.d/tru64/zabbix_agentd /etc/init.d/
vim /etc/init.d/zabbix_agentd              /稍微修改

DAEMON=/usr/local/zabbix/sbin/zabbix_agentd

chmod +x /etc/init.d/zabbix_agentd
cd

useradd -M -s /sbin/nologin zabbix

chown -R zabbix:zabbix /usr/local/zabbix/
cd /usr/local/zabbix/
mkdir logs
chown -R zabbix:zabbix logs/
cp /usr/local/zabbix/etc/zabbix_agentd.conf{,.bak}
vim /usr/local/zabbix/etc/zabbix_agentd.conf       

PidFile=/tmp/zabbix_agent.pid
Server=192.168.200.111
ServerActive=192.168.200.111
Hostname=agnet.zabbix.com
LogFile=/usr/local/zabbix/logs/zabbix_agentd.log
Include=/usr/local/zabbix/etc/zabbix_agentd.conf.d/*.conf
UnsafeUserParameters=1
UserParameter=mysql.version,mysql -V
UserParameter=mysql.status[*],/usr/local/zabbix/etc/chk_mysql.sh $1
UserParameter=mysql.ping,mysqladmin -uroot -p123 -P3306 -h192.168.200.112 ping | grep -c alive

service zabbix_agentd start
Zabbix agent started.
netstat -anpt | grep 10050
tcp 0 0 0.0.0.0:10050 0.0.0.0:* LISTEN 83251/zabbix_agentd

下一步就可以做监控了

二、做监控

 

 点击agent.zabbix.com——>选择模板

 

 

 三、zabbix监控mysql数据库

1、server.zabbix.com服务器操作

cd /usr/local/zabbix/etc/
vim zabbix_agentd.conf

PidFile=/tmp/zabbix_agentd.pid
Server=127.0.0.1,192.168.200.111
ServerActive=192.168.200.111
Hostname=server.zabbix.com
LogFile=/usr/local/zabbix/logs/zabbix_agentd.log
Include=/usr/local/zabbix/etc/zabbix_agentd.conf.d/*.conf

UnsafeUserParameters=1
UserParameter=mysql.version,mysql -V
UserParameter=mysql.ststus[*],/usr/local/zabbix/etc/chk_mysql.sh $1
UserParameter=mysql.ping,mysqladmin -uroot -p123 -P3306 -h192.168.200.111 ping | grep -c aliv

2、编辑chk_mysql.sh脚本

vim /usr/local/zabbix/etc/chk_mysql.sh

chmod 777 chk_mysql.sh                 //为脚本加权

mysql -uroot -p123          //mysql授权

3、server.zabbix.com测试

[root@server etc]# ln -s /usr/local/zabbix/bin/* /usr/local/bin/
[root@server etc]# zabbix_get -s 192.168.200.111 -k mysql.ping
1
[root@server etc]# zabbix_get -s 192.168.200.111 -k mysql.status[Com_update]            //会有一个数字，这里我没做出来

4、为server.zabbix.com添加服务模板

网页上：配置——>主机——>选择server.zabbix.com——>模板——>选择

 点击选择——>添加——>更新

5、创建MySQL服务图形

配置——>主机——>server.zabbix.com下的图形——>创建图形——>名称是：mysql.status、点击添加，找到MYSQL.status选择
