lamp参考：http://www.linuxidc.com/Linux/2016-11/136766.htm

安装httpd

    yum install httpd -y

    systemctl start httpd

    systemctl enable httpd

安装mysql

    rpm -ivh http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm

    systemctl start mysqld

    [root@linuxidc-web linuxidc]# mysql -u root

    #设置msyql密码为 123456

    mysql> set password for 'root'@'localhost' =password('123456');

    mysql> create database zabbix character set utf8 collate utf8_bin;

    #远程链接设置，全部以root帐号链接的远程用户，设其密码为 123456

    mysql> grant all privileges on zabbix.* to zabbix@'%' identified by 'zabbix';

                 grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix' ;

    #更新权限

    mysql>flush privileges;

    systemctl enable mysqld

安装php

    yum install php -y

    #安装php扩展，使支持mysql(这个实际上是可选的，yum安装mysql和zabbix时会根据依赖安装)

    yum install php-mysql php-gd libjpeg* php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-bcmath php-mhash -y

    systemctl restart mysqld

    systemctl restart httpd

安装zabbix agent

    rpm -ivh http://192.168.180.94/download/zabbix/zabbix-release-3.2-1.el7.noarch.rpm

    yum install zabbix-agent -y

    wget /etc/zabbix/zabbix_agentd.d -O http://192.168.180.94/download/zabbix/userparameter_nginx.conf

    内容：

    # worker process num 
    UserParameter=nginx.worker.num, ps -aux | grep nginx | grep -v grep | grep worker | wc -l | awk '{print $1}'

    # process mem, param1:proc_title key
    #UserParameter=nginx.worker.mem, ps -aux | grep -v grep | grep nginx | grep worker | awk '{sum += $1};END {print sum}'
    UserParameter=nginx.mem[*], ps -aux | grep -v grep | grep nginx | grep $1 | awk '{print $$6}'

    # process cpu, param1:proc_title key
    UserParameter=nginx.cpu[*], ps -aux | grep -v grep | grep nginx | grep $1 | awk '{print $$3}'

    # master process num
    UserParameter=nginx.master.num, ps -aux | grep nginx | grep -v grep | grep master | wc -l | awk '{print $$1}'

 

    systemctl enable zabbix-agent

    sed -i "s/\# Server=/Server=192.168.180.95/g" /etc/zabbix/zabbix_agentd.conf

    sed -i "s/\# ServerActive=/ServerActive=192.168.180.95/g" /etc/zabbix/zabbix_agentd.conf

    systemctl start zabbix-agent

    概念及使用说明：

    1，逻辑关系：主机组->主机->监控项组->监控项->触发器->告警动做->告警方式->用户组->用户

    2，建立主机时，能够选择所属主机组、关联模板

    3，模板，能够应用到主机组上，同时会显示相应主机，模板能够包括应用集、触发器、监控项和图形

    4，应用集，是一类有共同属性监控项的集合，应用集下包含一个或多个监控项，而监控项不必定属于应用集；应用集和监控项不是单独存在的，他们会与模板、主机关联

    5，监控项是监控的基本元素，每个监控项对应一个被监控端的采集值。属于某一个应用集的监控项，那么该监控项是应用集的子集，应用项的状态也就是监控项的状态；独立的属于某个模板或主机的监控项，那么它在模板或主机下建立，与模板与主机的状态保持一致

    6，触发器是存在于模板与主机中的子集，和监控项与模板、主机的地位一致，即：触发器能够在模板里面建立，而后关联到主机；也能够直接在主机里面建立直接关联主机
