zabbix 系统搭建(LAMP环境)+keepalived LVS配置
zabbix 系统搭建(LAMP环境)
先搭建好LAMP环境 (介绍)
安装zabbix监控主机 (设置监控主机ip为192.168.200.130)
wget http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm (下载rpm包,是zabbix的yum源)
rpm -ivh zabbix-release-3.2-1.e17.noarh.rpm (这里就是安装yum源)
yum install -y zabbix-agent zabbix-get zabbix-server-mysql zabbix-web zabbix-web-mysql
mysql搭建zabbix使用的库
步骤
● vim /etc/my.cnf //需要增加配置
character_set_server = utf8
● 重启mysqld服务后。进入mysql命令行,创建zabbix库
● creat database zabbix character set utf8;
● 再创建用户
● grant all on zabbix.* to 'zabbix'@'127.0.0.1' identified by 'aming-zabbix'
给库zabbix有所有权限
● 导入数据
● cd /usr/share/doc/zabbix-server-mysql-3.2.7
● gzip -d creat.sql.gz
● mysql -uroot -pXXX zabbix < creat.sql
● systemctl start httpd; systemctl enable httpd
● vim /etc/zabbix/zabbix_server.conf //修改或增加
DBHost=127.0.0.1 //在DBName=zabbix上面增加(这个要与mysql创建库的一样@XXXXX,来源ip)
DBUser=zabbix
DBPassword=aming-zabbix //在DBuser下面增加
● systemctl start zabbix-server
● systemctl enable zabbix-server
● netstat -lntp | grep zabbix //查看监听端口 10051
● 浏览器访问 http://ip.zabbix/ web界面下配置zabbix(如:http://192.168.200.130.zabbix)
● 用户名Admin 密码 zabbix
● 进入后台第一件事情就是该密码
如果时区错误,设置时区 vim /etc/php.ini
date.timezone = Asia/Shanghai
保存退出,再重启httpd(Apache)
Seal-server客户端安装
● wget http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm
● rpm -ivh zabbix-release-3.2-1.e17.noarh.rpm (这里就是安装yum源)
● yum install -y zabbix-agent
● vim /etc/zabbix/zabbix_agentd.conf //修改如下配置
Server=127.0.0.1 Server=192.168.200.130 //定义服务器端的ip (被动模式)
ServerActive=127.0.0.1 ServerActive=192.168.200.130 //定义服务器端的ip (主动模式)
Hostname=Zabbix server Hostname=Group02_118~122 //这是自定义的主机名,一会还需要在web界面下设置同样的主机名
● systemctl start zabbix-agent //启动zabbix-agent
● systemctl enable zabbix-agent //设置zabbix-agent开机启动
浏览器访问 http://ip.zabbix/ web界面下配置zabbix监控 客户端
配置分发器keepalived LVS配置
分发器主机SR:192.168.200.116 的设置
-
master主机192.168.200.116,安装keepalived ,
Yum install –y keepalived
(关闭防火墙+selinux清空iptables规则:
● systemctl stop firewalld; systemctl disable firewalld(必须关闭firwalld ,清空iptables的规则,关闭selinux)
● systemctl start iptables-services; iptables -F ;service iptables save
● 命令getenforce 查询selinux状态Enforcing 开启 /Disabled 关闭,临时关闭命令 setenforce 0
永久关闭 vim /etc/selinux/config 编辑SELINUX=disabled 重启也生效关闭selinux
#检查网关 route -n
) - vim /etc/keepalived/keepalived.conf 编辑配置,内容

保存退出
-
systemctl start keepalived 启动keepalived
ps aux|grep keepalived 查看keepalived是否启动
ip add 查看虚拟VIP 192.168.200.177 是否生效 - 查看设置虚拟IP,ipvsadm –ln ;
如果有其他规则ip 要先停止keepalived :systemctl stop keepalived
ipvsadm –C 清空虚拟ip,再启动 systemctl start keepalived
分发器备机SR:192.168.200.125 的设置
-
backup主机192.168.200.125,安装keepalived ,(资讯铭哥vip不可以是本机IP,117更换125)
Yum install –y keepalived

所有服务端:real-server 118~122操作
所有real-server 118~122都要执行
编写脚本vim /usr/local/sbin/lvs_dr.sh //内容如下
#!/bin/bash
vip=192.168.200.117
#把vip绑定在lo上,是为了实现rs直接把结果返回给客户端
ifdown lo
ifup lo
ifconfig lo:0 $vip broadcast $vip netmask 255.255.255.255 up
route add -host $vip lo:0
#以下操作为更改arp内核参数,目的是为了让rs顺利发送mac地址给客户端
#参考文档 http://www.cnblogs.com/lgfeng/archive/2012/10/16/2726308.html
echo "1" >/proc/sys/net/ipv4/conf/lo/arp_ignore
