实验环境


 

实验用2到2台机器,实验所用机器系统环境如下,可以看到2台机器的主机名和IP地址

[root@linux-node1 ~]# cat /etc/redhat-release 
CentOS Linux release 7.1.1503 (Core) 
[root@linux-node1 ~]# cat /etc/hosts

nginx自带的监控介绍


 

先学习下nginx自带的的状态监控

以下软件包是编译安装nginx需要的包

[root@linux-node1 ~]# yum install -y glibc gcc-c++ pcre-devel gcc openssl-devel

下载nginx稳定版并解压

[root@linux-node1 ~]# cd /usr/local/src/
[root@linux-node1 src]# ls
[root@linux-node1 src]# wget http://nginx.org/download/nginx-1.10.3.tar.gz

[root@linux-node1 src]# cd nginx-1.10.3
[root@linux-node1 nginx-1.10.3]# 

  

新建一个用户www,用于以普通用户运行nginx   ;配置,生成Makefile文件

[root@linux-node1 nginx-1.10.3]# useradd -s /sbin/nologin -M www
[root@linux-node1 nginx-1.10.3]# ./configure --prefix=/usr/local/nginx-1.10.3 \\
> --user=www --group=www \\
> --with-http_ssl_module \\
> --with-http_stub_status_module

 配置完毕,pcre是它默认加的,很多人编译使用--with-pcre 其实使用系统的就够了

checking for getaddrinfo() ... found
checking for PCRE library ... found
checking for PCRE JIT support ... found
checking for OpenSSL library ... found
checking for zlib library ... found

[root@linux-node1 nginx-1.10.3]# 

  

编译和安装

[root@linux-node1 nginx-1.10.3]# make && make install
 
make install 之后,其实这个目录可以拷贝到别的机器运行,但是你得保证这两台机器环境一致,必须安装的依赖包都一致

 

以上安装完毕,安装结尾部分如下

cp conf/nginx.conf \'/usr/local/nginx-1.10.3/conf/nginx.conf.default\'
test -d \'/usr/local/nginx-1.10.3/logs\' \\
	|| mkdir -p \'/usr/local/nginx-1.10.3/logs\'

	|| mkdir -p \'/usr/local/nginx-1.10.3/logs\'

	|| cp -R html \'/usr/local/nginx-1.10.3\'

	|| mkdir -p \'/usr/local/nginx-1.10.3/logs\'

[root@linux-node1 nginx-1.10.3]# echo $?
0
[root@linux-node1 nginx-1.10.3]# 

  

 

做软链接

[root@linux-node1 nginx-1.10.3]# cd
[root@linux-node1 ~]# ln -s /usr/local/nginx-1.10.3/ /usr/local/nginx
[root@linux-node1 ~]# 

怎么监控nginx,可以搜索一些做监控的产品他们做的文档,比较好,网站上很多人写的博客其实有的有错误,监控宝这种即使出现错误也不会太大  

搜索监控宝的nginx相关的wiki

http://www.jiankongbao.com/search.php?q=nginx

 

 

 http://wiki.jiankongbao.com/doku.php/%E6%96%87%E6%A1%A3:%E5%AE%89%E5%85%A8%E6%8C%87%E5%BC%95#nginx_监控

 

 

需要注意的是,Nginx默认安装不包含状态模块stub_status,所以,在编译Nginx的时候,需要添加以下参数:

--with-http_stub_status_module

一旦包含stub_status模块后,我们就可以在配置文件nginx.conf中开启状态页面:  

http {
    server {
        listen       80;
        server_name  localhost;

        location / {
            root   html;
            index  index.html index.htm;
        }

        location /nginx-status {
            stub_status on;
            access_log  off;
        }
    }
}

以上配置文件中,我们实际增加的部分是:

  location /nginx-status {
            stub_status on;
            access_log  off;
        }

同样,假如Nginx所在服务器的IP为10.0.0.1,同时指向它的域名为www.domain.com,这样一来,Nginx的状态页面便是:

http://10.0.0.1/nginx-status

或者

http://www.domain.com/nginx-status

同样,建议您将以上示例中的nginx-status修改为其它字符串。

另外,Nginx的stub_status也支持授权IP的配置,您可以参考Nginx的手册,监控宝提供的服务监控点IP地址为:

 

 

开始操作修改nginx.conf

[root@linux-node1 ~]# cd /usr/local/nginx/conf/
[root@linux-node1 conf]# vim nginx.conf

编辑如下,顺便加上访问控制

 

 修改完毕,检测语法,启动,检查

[root@linux-node1 conf]# vim nginx.conf
[root@linux-node1 conf]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx-1.10.3/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx-1.10.3/conf/nginx.conf test is successful
[root@linux-node1 conf]# /usr/local/nginx/sbin/nginx 
[root@linux-node1 conf]# lsof -i:80
COMMAND   PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
nginx   10245 root    6u  IPv4 157419      0t0  TCP *:http (LISTEN)
nginx   10246  www    6u  IPv4 157419      0t0  TCP *:http (LISTEN)
[root@linux-node1 conf]# 

网页上查看

 

 

关于状态页面的解释
Active connections: 4
server accepts handled requests
4 4 23
Reading: 0 Writing: 3 Waiting: 0

Active connections:对后端发起的活动连接数。
Server accepts handled requests:Nginx总共处理了4个连接,成功创建4次握手(证明中间没有失败的),总共处理了23个请求。
Reading:Nginx 读取到客户端的Header信息数。
Writing:Nginx 返回给客户端的Header信息数。
Waiting:开启keep-alive的情况下,这个值等于 active – (reading + writing),意思就是Nginx已经处理完成,正在等候下一次请求指令的驻留连接。

 

监控要做的事,最基础的部分如下:
采集,存储,展示,告警

nagios和zabbix对于一些大量主机需要监控的场景时,nagios不如zabbix
nagios监控就有瓶颈了。因为server端主动访问,1000台就有瓶颈了
zabbix主动模式完全解决,顶多就是server端的读写压力

 

 

 

 

安装zabbix3.0


 

 
一、配置yum并安装zabbix3.0
 
zabbix3.0 编译安装各种坑,建议yum安装

在安装之前请确保防火墙以及selinux关闭,并做好时间同步

1.1、yum源配置

rpm -ivh http://mirrors.aliyun.com/zabbix/zabbix/3.0/rhel/7/x86_64/zabbix-release-3.0-1.el7.noarch.rpm

1.2、安装相关软件

zabbix把数据放到了库里,它支持mysql,centos7之后mysql默认是mariadb

yum install zabbix-server zabbix-web zabbix-server-mysql zabbix-web-mysql mariadb-server mariadb zabbix-agent  -y

zabbix运行的web容器是apache,它默认把apache作为依赖安装上了

安装完毕,留意下版本

[root@linux-node1 ~]# yum install zabbix-server zabbix-web zabbix-server-mysql zabbix-web-mysql mariadb-server mariadb zabbix-agent  -y
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile

Package zabbix-agent-3.0.8-2.el7.x86_64 already installed and latest version
Nothing to do
[root@linux-node1 ~]# 

1.3、修改PHP时区配置

 

 

 由于注释里带#,这里\'s###g\'  改成\'s@@@g\'  结构替换

sed -i \'s@# php_value date.timezone Europe/Riga@php_value date.timezone Asia/Shanghai@g\' /etc/httpd/conf.d/zabbix.conf

  

 替换完毕。

 

 

二、数据库配置

Centos7上MySQL已经变成了mariadb。

2.1、启动数据库

systemctl start mariadb

2.2、创建zabbix所用的数据库及用户 

mysql
create database zabbix character set utf8 collate utf8_bin;
grant all on zabbix.* to zabbix@\'localhost\' identified by \'zabbix\';
exit

导入数据

zcat命令用于不真正解压缩文件,就能显示压缩包中文件的内容的场合。

[root@linux-node1 ~]# cd /usr/share/doc/zabbix-server-mysql-3.0.8/
[root@linux-node1 zabbix-server-mysql-3.0.8]# ls
AUTHORS  ChangeLog  COPYING  create.sql.gz  NEWS  README
[root@linux-node1 zabbix-server-mysql-3.0.8]# zcat create.sql.gz | mysql -uzabbix -pzabbix zabbix
[root@linux-node1 zabbix-server-mysql-3.0.8]# 

2.3、修改zabbix配置

vim /etc/zabbix/zabbix_server.conf

取消下面注释,并修改成正确值

DBHost=localhost #数据库所在主机
DBName=zabbix #数据库名
DBUser=zabbix #数据库用户
DBPassword=zabbix #数据库密码

2.4、启动zabbix及http

遇到问题,zabbix-server启动失败,httpd启动成功

[root@linux-node1 ~]# systemctl start zabbix-server
Job for zabbix-server.service failed because a fatal signal was delivered to the control process. See "systemctl status zabbix-server.service" and "journalctl -xe" for details.
[root@linux-node1 ~]# systemctl start httpd

升级  trousers之后,启动zabbix-server成功(系统版本centos7-1503)

[root@linux-node1 ~]# yum update trousers

三、通过浏览器配置zabbix-server

浏览器里输入下面内容,通过页面安装配置

http://192.168.58.11/zabbix

 

 

 一切OK

 

密码也是zabbix

 

 

 name这里可以自定义,它出出现在登录后的右上角

 

 

 

 其实以上步骤就是配置了下面文件

 

点击Finish出现登录界面,用户名和密码默认是Admin/zabbix

 

 

 

 

 启动zabbix-agent,它默认监听10050端口

zabbix-server默认监听10051端口

[root@linux-node1 ~]# systemctl start zabbix-agent
[root@linux-node1 ~]# netstat -lntp

[root@linux-node1 ~]# 

  

 

 

zabbix页面登录和介绍 


 

登录成功的界面

 

 启用此监控

 

 

 

 

 它是php-gd绘制的

 

zabbix-web可以单独一台机器,可以和zabbix-server分开
share这里可以看到别人写好的模板,可以直接拿来用

 

 

 

 

 
zabbix自定义监控项
 
生产要先创建主机组

 

 

 

练习创建3个组:web,memcached,lb

 

 

 

 

主机组的名字建议是英文,否则二次开发的时候就知道难受了
主机名也建议写本来的主机名,二次开发的时候能对应上,该是啥主机名就是啥,也可以使用IP地址

 

 

 

 zabbix也支持snmp,这台机器开启了snmp,这里我们就用snmp来监控

 

 snmp这里由于是本机监控本机可以写127.0.0.1

其实推荐写成真实IP

 

 

生产环境加描述,工作中建议约定好,比如时间信息等,方便自己也方便他人

 

 

 模板这里添加snmp的模板

 

 

 

使用snmp的话,宏定义这里必须写,宏类似定义个变量

 

 宏就是下面这个值

[root@linux-node1 ~]# cat /etc/snmp/snmpd.conf
rocommunity nmap 192.168.58.11
[root@linux-node1 ~]# 

 

输入如下内容 

 

 

 添加完毕,看到有很多模板显示,其实括号里的都是模板的链接

 

如果snmp没启动,需要先启动它

[root@linux-node1 ~]# systemctl enable snmpd
Created symlink from /etc/systemd/system/multi-user.target.wants/snmpd.service to /usr/lib/systemd/system/snmpd.service.
[root@linux-node1 ~]# systemctl start snmpd
[root@linux-node1 ~]# netstat -luntp | grep 161
udp        0      0 0.0.0.0:161             0.0.0.0:*                           2549/snmpd          
[root@linux-node1 ~]# 

 

页面里查看,snmp监控也成功了

 

screen是几个图形放一起;2.4需要在configure下面创建;在3.0可以在monitor下创建

 

 

 

自定义监控项
准备使用zabbix监控nginx连接数,把之前安装的nginx配置改成8080端口
[root@linux-node1 ~]# cd /usr/local/nginx/conf/
[root@linux-node1 conf]# vim nginx.conf
[root@linux-node1 conf]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx-1.10.3/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx-1.10.3/conf/nginx.conf test is successful
[root@linux-node1 conf]# /usr/local/nginx/sbin/nginx 
[root@linux-node1 conf]# lsof -i:8080
COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
nginx   2714 root    6u  IPv4  35149      0t0  TCP *:webcache (LISTEN)
nginx   2715  www    6u  IPv4  35149      0t0  TCP *:webcache (LISTEN)
[root@linux-node1 conf]# 

  

先用命令方式获取活动连接数

[root@linux-node1 conf]# curl http://192.168.58.11:8080/nginx-status
Active connections: 1 
server accepts handled requests
 4 4 4 
Reading: 0 Writing: 1 Waiting: 0 
[root@linux-node1 conf]# curl http://192.168.58.11:8080/nginx-status | grep Active
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100    97  100    97    0     0  54525      0 --:--:-- --:--:-- --:--:-- 97000
Active connections: 1 
[root@linux-node1 conf]# curl -s http://192.168.58.11:8080/nginx-status | grep Active
Active connections: 1 
[root@linux-node1 conf]# curl -s http://192.168.58.11:8080/nginx-status | grep Active |awk  \'{print $3}\'
1
[root@linux-node1 conf]# curl -s http://192.168.58.11:8080/nginx-status | grep Active |awk  \'{print $NF}\'
1
[root@linux-node1 conf]# 

  

 vim /etc/zabbix/zabbix_agentd.conf

 默认zabbix-agent的配置文件会加载下面目录,因此可以单独新建一个文件,用于存放自定义的key

 

 写一个名叫nginx.conf的配置文件

[root@linux-node1 zabbix_agentd.d]# pwd
/etc/zabbix/zabbix_agentd.d
[root@linux-node1 zabbix_agentd.d]# cat nginx.conf 
UserParameter=nginx.active,curl -s http://192.168.58.11:8080/nginx-status | grep Active |awk  \'{print $NF}\'
[root@linux-node1 zabbix_agentd.d]# 

  

 优化一下,脚本里的命令使用绝对路径

[root@linux-node1 zabbix_agentd.d]# which curl
/usr/bin/curl
[root@linux-node1 zabbix_agentd.d]# vim nginx.conf
[root@linux-node1 zabbix_agentd.d]# cat nginx.conf 
UserParameter=nginx.active,/usr/bin/curl -s http://192.168.58.11:8080/nginx-status | grep Active |awk  \'{print $NF}\'
[root@linux-node1 zabbix_agentd.d]# 

  

 重启agent,安装zabbix-get工具,它是个测试工具,只有它能获取到了自定义的key的值,才能加入到zabbix-server里。

[root@linux-node1 ~]# systemctl restart zabbix-agent
[root@linux-node1 ~]# yum install -y zabbix-get

  

 get一下,发现有问题

[root@linux-node1 ~]# zabbix_get -s 192.168.58.11 -p 10050 -k"nginx.active"
zabbix_get [3070]: Check access restrictions in Zabbix agent configuration
[root@linux-node1 ~]# 

因为安装zabbix-agent的时候,Server那里写的是127.0.0.1,agent和server在一台
Server那里要写192.168.58.11
zabbix-get或者这里写127.0.0.1
下面改成192.168.58.11,这里是只允许哪个server的IP访问自己,server这里也支持多Ip

改完重启下agent

[root@linux-node1 ~]# vim /etc/zabbix/zabbix_agentd.conf 
[root@linux-node1 ~]# systemctl restart zabbix-agent
[root@linux-node1 ~]# 

再次获取,成功

[root@linux-node1 ~]# zabbix_get -s 192.168.58.11 -p 10050 -k"nginx.active"
1
[root@linux-node1 ~]# 

网页上这里尽量也改掉

 改成如下,否则会报连接故障

 

 

 

总结添加自定义监控项的步骤
1、命令行或脚本先获取成功
2、配置文件里添加用户自定义参数
3、重启zabbix-agent
4、server端使用zabbix_get测试获取
5、web界面创建item

 

 这里还缺最后一步,web页面添加自定义监控项

 

 

 

application这里写个自定义的,它是一组item的集合

创建图形

 

 

 

找到nginx.active

 

 

 

 查看图形

 

 

 手动制造点连接数数据

 查看图形数据

以堆叠方式显示

 

 堆叠方式就是这种

创建自定义的screen

 

 把nginx.active这个图形加上去

 

 

 把相关联的加到一个screen里面

 

 

 其实可以显示很多,比如文本

 

 

 

还能显示url

 

它就能把上面的url显示出来

 

 

zabbix  还可以自定义map

 

拓扑图,目前比较鸡肋,上百台机器没法画,太复杂
