一、Zabbix监控mysql数据库

1、为server.Zabbix.com添加服务模板

2、创建mysql服务图形

添加图形的操作

二、server.zabbix.com服务器操作

[root@server ~]# cd /usr/local/zabbix/etc/

[root@server etc]# vim zabbix_agentd.conf
PidFile=/tmp/zabbix_agentd.pid
Server=127.0.0.1,192.168.2.20
ServerActive=192.168.2.20
Hostname=server.zabbix.com                  
LogFile=/usr/local/zabbix/logs/zabbix_agentd.log
Include=/usr/local/zabbix/etc/zabbix_agentd.conf.d/*.conf
UnsafeUserParameters=1		        #允许所有字符的参数传递给用户定义的参数。
UserParameter=mysql.version,mysql -V		    #定义键值mysql.version，以及键值的值mysql -V
UserParameter=mysql.status[*],/usr/local/zabbix/etc/chk_mysql.sh $1			    #定义键值mysql.status[*]
UserParameter=mysql.ping,mysqladmin -uroot -p123123 -P3306 -h192.168.2.20  ping | grep -c alive		            #定义键值mysql.ping，指定chk_mysql.sh脚本，使用此脚本检查mysql的运行状态，使用mysqladmin命令指定agent端的数据库连接用户密码ip地址，注意保证mysqladmin命令的链接；

编辑chk_mysql.sh脚本

[root@server etc]# pwd
/usr/local/zabbix/etc
[root@server etc]# vim chk_mysql.sh

[root@server etc]# killall -9 zabbix_agentd
[root@server etc]# killall -9 zabbix_server

[root@server etc]# /usr/local/zabbix/sbin/zabbix_agentd 
[root@server etc]# /usr/local/zabbix/sbin/zabbix_server

[root@server etc]# netstat -anpt | egrep ':10050|10051'

三、server.Zabbix.com测试

[root@server etc]# ln -s /usr/local/zabbix/bin/* /usr/local/bin/

[root@server etc]# zabbix_get -s 192.168.2.20 -k mysql.ping
1

[root@server etc]# zabbix_get -s 192.168.2.20 -k mysql.status[Com_update]
3164

四、查看web效果

五、Zabbix监控apache（httpd服务）

[root@server ~]# vim /opt/check_httpd.sh

#!/bin/bash
#
netstat -lnpt |grep -q :80
if [ $? -eq 0 ]
then
        echo "1"
else
        echo "0"
fi
[root@server ~]#chmod +x /opt/check_httpd.sh anaconda-ks.cfg  

[root@server ~]# vim /usr/local/zabbix/etc/zabbix_agentd.conf  
UnsafeUserParameters=1
UserParameter=httpd.status,/opt/check_httpd.sh    

[root@server ~]#killall -9 zabbix_agentd

[root@server ~]#zabbix_agentd

[root@server ~]# ln -s /usr/local/zabbix/bin/zabbix_get /usr/local/bin/zabbix_get

[root@server ~]# zabbix_get -s 192.168.2.20 -p 10050 -k httpd.status

[root@serve ~]# which netstat
/usr/bin/netstat

[root@serve~]# chmod u+s /usr/bin/netstat

[root@server ~]# zabbix_get -s 192.168.2.20 -p 10050 -k httpd.status

[root@server ~]#systemctl stop httpd
