环境说明:
zabbix服务器: 192.168.100.1 服务端 （已经装好zabbix_agentd和zabbix_server，且为MySQL主）
zabbix客户端: 192.168.100.128 客户端 （已经装好zabbix_agentd，已经安装好apache服务，且为MySQL从，数据库没有密码）
监视客户端的apache进程：
关闭两台机器的防火墙和selinux：
[root@zabbix ~]# systemctl stop firewalld [root@zabbix ~]# setenforce 0
以查看进程方式过滤apache进程，输出1表示进程有问题，0表示没问题
[root@zabbix ~]# cat /scripts/check_process.sh #!/bin/bash count=$(ps -ef |grep -Ev "grep|$0" | grep -c "$1") if [ $count -eq 0 ]; then echo "1" else echo "0" fi //给脚本执行权限 [root@zabbix ~]# chmod +x /scripts/check_process.sh //源码安装执行此脚本要加绝对路径 [root@zabbix ~]# /scripts/check_process.sh httpd 0 [root@zabbix ~]# ss -antl State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 0.0.0.0:22 0.0.0.0:* LISTEN 0 128 0.0.0.0:10050 0.0.0.0:* LISTEN 0 128 0.0.0.0:9000 0.0.0.0:* LISTEN 0 128 [::]:22 [::]:* LISTEN 0 80 *:3306 *:* LISTEN 0 128 *:80 *:* //在文件的最后面加上两行开启自定义监控的配置 UnsafeUserParameters=1 UserParameter=check_apache,/scripts/check_process.sh httpd //客户端这边关闭了apache的进程 [root@zabbix ~]# ss -antl State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 0.0.0.0:22 0.0.0.0:* LISTEN 0 128 0.0.0.0:10050 0.0.0.0:* LISTEN 0 128 0.0.0.0:9000 0.0.0.0:* LISTEN 0 128 [::]:22 [::]:* LISTEN 0 80 *:3306 *:* //在服务端上查看能否取到刚才配置脚本的值 [root@zabbix ~]# zabbix_get -s 192.168.100.128 -k check_apache 1 //能取到1说明没问题了
配置网页zabbix的流程
添加主机监控之类的操作请参考zabbix监控配置
这里的HOST.NAME别写错了
//受控机手动触发报警 [root@zabbix ~]# apachectl start [root@zabbix ~]# apachectl stop
配置监控日志流程
//当前在受控机 [root@zabbix scripts]# pwd /scripts [root@zabbix ~]# dnf -y install python36 第一个参数为日志文件名（必须有，相对路径、绝对路径均可） 第二个参数为seek position文件的路径（可选项，若不设置则默认为/tmp/logseek文件。相对路径、绝对路径均可） 第三个参数为搜索关键字，默认为 Error [root@zabbix scripts]# vim log.py #!/usr/bin/env python3 import sys import re def prePos(seekfile): global curpos try: cf = open(seekfile) except IOError: curpos = 0 return curpos except FileNotFoundError: curpos = 0 return curpos else: try: curpos = int(cf.readline().strip()) except ValueError: curpos = 0 cf.close() return curpos cf.close() return curpos def lastPos(filename): with open(filename) as lfile: if lfile.readline(): lfile.seek(0,2) else: return 0 lastPos = lfile.tell() return lastPos def getSeekFile(): try: seekfile = sys.argv[2] except IndexError: seekfile = ‘/tmp/logseek‘ return seekfile def getKey(): try: tagKey = str(sys.argv[3]) except IndexError: tagKey = ‘Error‘ return tagKey def getResult(filename,seekfile,tagkey): destPos = prePos(seekfile) curPos = lastPos(filename) if curPos < destPos: curpos = 0 try: f = open(filename) except IOError: print(‘Could not open file: %s‘ % filename) except FileNotFoundError: print(‘Could not open file: %s‘ % filename) else: f.seek(destPos) while curPos != 0 and f.tell() < curPos: rresult = f.readline().strip() global result if re.search(tagkey, rresult): result = 1 break else: result = 0 with open(seekfile,‘w‘) as sf: sf.write(str(curPos)) finally: f.close() return result if __name__ == "__main__": result = 0 curpos = 0 tagkey = getKey() seekfile = getSeekFile() result = getResult(sys.argv[1],seekfile,tagkey) print(result) [root@zabbix scripts]# chmod +x log.py [root@zabbix scripts]# touch /usr/local/apache/logs/error.log //在文件最后添加 [root@zabbix scripts]# vim /usr/local/etc/zabbix_agentd.conf UserParameter=check_logs[*],/scripts/log.py $1 $2 $3 [root@zabbix scripts]# pkill zabbix [root@zabbix scripts]# zabbix_agentd //在服务端上查看能否取到刚才配置py脚本的值 [root@zabbix ~]# zabbix_get -s 192.168.100.128 -k check_logs["/usr/local/apache/logs/error.log","/tmp/seek","Error"] //手动触发报警 [root@zabbix scripts]# echo ‘Error‘ >> /usr/local/apache/logs/error.log
