UserParameter=apache[*],/usr/local/bin/zapache.sh \$1

2.      #mvcheck_apache /usr/local/zabbix/bin

3.      #chmod+x /usr/local/zabbix/bin/check_apache #授权可执行权限

4.      修改脚本#vim–n check_apache

按键128

Apacheversion=…修改正确的apache安装路径

5.      修改配置文件#vim/etc/zabbix_agentd.cof

启用并修改正确的zabbix路径：include=/usr/local/zabbix/etc/zabbix_agent.conf.d/*.conf

移动配置文件conf-apache.conf到zabbix_agent配置目录下#mv conf-apache.conf /usr/local/zabbix/etc/zabbix_agentd.conf.d/

修改此文件#vim /usr/local/zabix/etc/zabbix_agent.conf.d/conf-apache.conf

UserParameter=apache[*],/usr/local/zabbix/bin/check_apache    \$1 //修改成正确路径

6.      配置httpd文件

#vim /etc/httpd/conf/httpd.conf

末尾添加

#

# Allow server statusreports generated by mod_status,

# with the URL ofhttp://servername/server-status

 

# Uncomment and changethe "192.0.2.0/24" to allow access from other hosts.

#

SetHandlerserver-status

Order deny,allow

Deny from all

Allow from127.0.0.1  ::1

Allow from192.168.0.0/24

# Keep track ofextended status information for each request

ExtendedStatus On

# Determine ifmod_status displays the first 63 characters of a request or

# the last 63, assumingthe request itself is greater than 63 chars.

# Default: Off

#SeeRequestTail On

# Show ProxyLoadBalancer status in mod_status

ProxyStatus On

重启服务#service httpd restart

7.      测试脚本是否正常#./check_apache –h

MySQL

1.      进入MySQL数据库创建用户zabbix，并且给权限

Mysql>grant all on *.* to “zabbix-monitor”@”%” identified by ‘123456’

Mysql>flush privileges

Mysql>quit

2.      我使用的是zabbix自带的MySQL监控脚本

复制#cp/usr/local/src/zabbix-3.0.5/conf/zabbix_agentd/userparameter_mysl.conf  /usr/local/zabbix/etc/zabbix_agentd.conf.d/

修改#vim /usr/local/zabbix/etc/zabbix_agentd.conf

启用并修改正确的路径

Include=/usr/local/zabbix/etc/zabbix_agentd.conf.d/*.conf  

3.      建立数据库和zabbix的链接信息#vim /usr/local/zabbix/etc/.my.cnf

#Zabbix Agent

[mysql]

host=localhost

user=zabbix-monitor

password=123456

socket=/var/lib/mysql/mysql.sock

[mysqladmin]

host=localhost

 user=zabbix-monitor

password=123456

socket= /var/lib/mysql/mysql.sock

:wq

4.      修改#vim/usr/local/zabbix/etc/zabbix_agentd.conf.d/userparameter_mysql.conf

将home=/var/lib/zabbix全部改成home=/usr/local/zabbix/etc/

5.      重启zabbix_agent服务#service zabbix_agentd restart

6.      Zabbix前端配置
