监控MySQL服务及httpd服务

一：监控MySQL服务

UserParameter=mysql.ping,mysqladmin -uroot -p123123 -P3306 -h192.168.200.11 ping | grep -c alive

二：监控httpd服务

[root@server etc]# vim /usr/local/zabbix/etc/zabbix_agentd.conf
PidFile=/tmp/zabbix_agentd.pid
Server=127.0.0.1,192.168.200.11
ServerActive=192.168.200.11
stname=server.zabbix.com
LogFile=/usr/local/zabbix/logs/zabbix_agentd.log
Include=/usr/local/zabbix/etc/zabbix_agentd.conf.d/*.conf

UserParameter=httpd.status,/usr/local/zabbix/etc/chk_httpd.sh #添加一条引用httpd的脚本

[root@server etc]# vim chk_httpd.sh #准备脚本
#!/bin/bash
#检查httpd服务是否正常运行，正常输出1不正常输出2

netstat -lnupt | grep -q :80
if [ $? -eq 0 ];then
        echo "1"
else
        echo "0"
fi
~

[root@server etc]# chmod 777 chk_httpd.sh #给脚本加权限

#重启zabbix_agentd服务

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

[root@server etc]# /usr/local/zabbix/bin/zabbix_get -s 192.168.200.11 -k httpd.status

[root@server etc]# which netstat
/usr/bin/netstat
[root@server etc]# chmod u+s /usr/bin/netstat
[root@server etc]# /usr/local/zabbix/bin/zabbix_get -s 192.168.200.11 -k httpd.status

三：磁盘监控

[root@server ~]# vim /usr/local/zabbix/etc/zabbix_agentd.conf
PidFile=/tmp/zabbix_agentd.pid
Server=127.0.0.1,192.168.200.11
ServerActive=192.168.200.11
Hostname=server.zabbix.com
LogFile=/usr/local/zabbix/logs/zabbix_agentd.log
Include=/usr/local/zabbix/etc/zabbix_agentd.conf.d/*.conf

UserParameter=httpd.status,/usr/local/zabbix/etc/chk_httpd.sh
UserParameter=sdb1.used,df -hT| awk -F'[ %]' 'NR==7{ print $(NF-2)}' #引入命令

#重启服务

[root@server ~]# killall -9 zabbix_agentd
[root@server ~]# zabbix_agentd
[root@server ~]# /usr/local/zabbix/bin/zabbix_get -s 192.168.200.11 -k sda1.used
