第二篇【Zabbix客户端的完整布署】

关于Zabbix服务端布署请查看

1、上传zabbix安装包（源码包默认（Server和Agent是一起的））

[root@sms-v2 ~]# ll /root/
-rw-r--r--   root root  11月  : zabbix-4.4..tar.gz

2、安装依赖包

[root@sms-v2 ~]# yum install gcc gcc-c++ pcre-devel -y

3、创建运行用户

#创建组用户
[root@sms-v2 ~]# groupadd zabbix

#创建用户
[root@sms-v2 ~]# useradd -g zabbix -M -s /sbin/nologin zabbix

#检查是否创建成功
[root@sms-v2 ~]# id zabbix
uid=(zabbix) gid=(zabbix) 组=(zabbix)

 4、软件的安装

#解压软件
[root@sms-v2 ~]# tar xvf zabbix-4.4..tar.gz 

#进入软件安装目录
[root@sms-v2 ~]# cd zabbix-4.4./

#安装软件
[root@sms-v2 zabbix-4.4.3]# ./configure --prefix=/data/application/zabbix-4.4.3 --enable-agent

#编译安装
[root@sms-v2 zabbix-4.4.3]# make && make install

#安装完成的目录

[root@sms-v2 zabbix-4.4.3]# tree /data/application/zabbix-4.4.3/
/data/application/zabbix-4.4.3/
├── bin
│   ├── zabbix_get
│   └── zabbix_sender
├── etc
│   ├── zabbix_agentd.conf
│   └── zabbix_agentd.conf.d
├── lib
│   └── modules
├── sbin
│   └── zabbix_agentd
└── share
└── man
├── man1
│   ├── zabbix_get.1
│   └── zabbix_sender.1
└── man8
└── zabbix_agentd.8

 5、创建存放日志的目录

[root@sms-v2 zabbix-4.4.]# mkdir /data/application/zabbix-4.4./log
[root@sms-v2 zabbix-4.4.]# chown zabbix.zabbix /data/application/zabbix-4.4./log -R

6、编译zabbix Agent配置文件

[root@sms-v2 zabbix-4.4.3]# vi /data/application/zabbix-4.4.3/etc/zabbix_agentd.conf
...
       # Mandatory: no
      # Default:
      # PidFile=/tmp/zabbix_agentd.pid
      PidFile=/data/application/zabbix-4.4.3/log/zabbix_agentd.pid
     
      ### Option: LogType
      #       Specifies where log messages are written to:
      #               system  - syslog
      #               file    - file specified with LogFile parameter
      #               console - standard output
...
      #       Log file name for LogType 'file' parameter.
      #
      # Mandatory: yes, if LogType is set to file, otherwise no
      # Default:
      # LogFile=

      LogFile=/data/application/zabbix-4.4.3/log/zabbix_agentd.log #日志文件位置
     
      ### Option: LogFileSize
      #       Maximum size of log file in MB.
      #        - disable automatic log rotation.
      #
      # Mandatory: no
      # Range: -
      # Default:
      # LogFileSize=
...
      ### Option: Server
      #       List of comma delimited IP addresses, optionally in CIDR notation, or DNS names of Zabbix servers and Zabbix proxies.
      #       Incoming connections will be accepted only from the hosts listed here.
      #       If IPv6 support is enabled then '127.0.0.1', '::127.0.0.1', '::ffff:127.0.0.1' are treated equally
      #       and '::/0' will allow any IPv4 or IPv6 address.
      #       '0.0.0.0/0' can be used to allow any IPv4 address.
      #       Example: Server=127.0.0.1,192.168.1.0/,::,:db8::/,zabbix.example.com
      #
      # Mandatory: yes, if StartAgents is not explicitly set to
      # Default:
      # Server=

      Server=127.0.0.1,192.168.10.96 #Zabbix Server主动监控允许调用

      ### Option: ListenPort
      #       Agent will listen on this port for connections from the server.
      #
...
     ##### Active checks related

     ### Option: ServerActive
     #       List of comma delimited IP:port (or DNS name:port) pairs of Zabbix servers and Zabbix proxies for active checks.
     #       If port is not specified, default port is used.
     #       IPv6 addresses must be enclosed in square brackets if port for that host is specified.
     #       If port is not specified, square brackets for IPv6 addresses are optional.
     #       If this parameter is not specified, active checks are disabled.
     #       Example: ServerActive=127.0.0.1:,zabbix.domain,[::]:,::,[12fc::]
     #
     # Mandatory: no
     # Default:
     # ServerActive=

     ServerActive=192.168.10.96:10051 #Aget被动监控，即主机上传数据到Zabbix服务器
...
     ### Option: Hostname
     #       Unique, case sensitive hostname.
     #       Required for active checks and must match hostname as configured on the server.
     #       Value is acquired from HostnameItem if undefined.
     #
     # Mandatory: no
     # Default:
     # Hostname=

     Hostname=192.168.10.95 #配置主机名，建议配置为IP地址
...
     ### Option: User
     #       Drop privileges to a specific, existing user on the system.
     #       Only has effect if run as 'root' and AllowRoot is disabled.
     #
     # Mandatory: no
     # Default:
     User=zabbix #运行Agent的用户
...
     ### Option: Include
     #       You may include individual files or all files in a directory in the configuration file.
     #       Installing Zabbix will create include directory in /usr/local/etc, unless modified during the compile time.
     #
     # Mandatory: no
     # Default:
     # Include=

     # Include=/usr/local/etc/zabbix_agentd.userparams.conf
     # Include=/usr/local/etc/zabbix_agentd.conf.d/
     # Include=/usr/local/etc/zabbix_agentd.conf.d/*.conf
    290 Include=/data/application/zabbix-4.4.3/etc/zabbix_agentd.conf.d/*.conf #配置文件的位置
...

7、编写zabbix Agent启动服务

[root@sms-v2 init.d]# cat /etc/init.d/zabbix_agentd
#!/bin/sh

##########################################################
###### Zabbix agent daemon init script
##########################################################

zabbix_agentd_sbin=/data/application/zabbix-4.4./sbin/zabbix_agentd
zabbix_etc=/data/application/zabbix-4.4./etc/zabbix_agentd.conf
PidFile=/data/application/zabbix-4.4./log/zabbix_agentd.pid

case $ in

start)
        $zabbix_agentd_sbin -c $zabbix_etc ;;

stop)
        kill -TERM `cat $PidFile` ;;

restart)
        $ stop
        sleep
        $ start
        ;;

*)
        echo "Usage: $0 start|stop|restart"
        exit
esac

zabbix_agentd

#设置可执行权限
[root@sms-v2 ~]# chmod  /etc/init.d/zabbix_agentd

#zabbix agent开启、关闭、重启
[root@sms-v2 ~]# /etc/init.d/zabbix_agentd start

[root@sms-v2 ~]# /etc/init.d/zabbix_agentd stop

[root@sms-v2 ~]# /etc/init.d/zabbix_agentd restart

#这里需要开启zabbix agent服务

8、查看zabbix agent日志

[root@sms-v2 ~]# tail -f /data/application/zabbix-4.4./log/zabbix_agentd.log
 ::101616.707 TLS support:            NO
 ::101616.707 **************************
 ::101616.707 using configuration file: /data/application/zabbix-4.4./etc/zabbix_agentd.conf
 ::101616.707 agent # started [main process]
 ::101616.708 agent # started [collector]
 ::101616.709 agent # started [listener #]
 ::101616.710 agent # started [listener #]
 ::101616.710 agent # started [active checks #]
 ::101616.711 agent # started [listener #]
 ::101616.712 active check configuration update from [192.168.10.96:10051] started to fail (cannot connect to [[192.168.10.96]:10051]: [113] No route to host)
#这里的原因，因为zabbix服务端的端口没有在防火墙开放，导致agent连接不到服务端
#解决方法
#在zabbix服务端开放端口10051

[root@filestore-v2 ~]# firewall-cmd --permanent --add-port=10051/tcp
success
[root@filestore-v2 ~]# firewall-cmd --reload
success

agent端的服务器操作如下

[root@sms-v2 ~]# firewall-cmd --permanent --add-port=10050/tcp
success
[root@sms-v2 ~]# firewall-cmd --reload
success

再次查看日志

[root@sms-v2 ~]# tail -f /data/application/zabbix-4.4.3/log/zabbix_agentd.log
75987:20191224:101616.707 agent #0 started [main process]
75988:20191224:101616.708 agent #1 started [collector]
75991:20191224:101616.709 agent #4 started [listener #3]
75989:20191224:101616.710 agent #2 started [listener #1]
75992:20191224:101616.710 agent #5 started [active checks #1]
75990:20191224:101616.711 agent #3 started [listener #2]
75992:20191224:102216.927 active check configuration update from [192.168.10.96:10051] is working again  
75992:20191224:102216.927 no active checks on server [192.168.10.96:10051]: host [192.168.10.95] not found 
#解决方法：

这个原因，检查zabbix服务端的主机信息，是否跟当前的agent端的配置信息一样，比如主机名或IP地址在Server端与Agent端是否配置一样

 9、在zabbix服务端利用自带的工具zabbix_get获取agent端的数据

#查看命令的使用方法
[root@filestore-v2 ~]# /data/application/zabbix-4.4./bin/zabbix_get --help
usage:
  zabbix_get -s host-name-or-IP [-p port-number] [-I IP-address] -k item-key
  zabbix_get -h
  zabbix_get -V
General options:
  -s --host host-name-or-IP  获取数据的IP地址
  -p --port port-number      获取数据的端口 (默认端口: )
  -I --source-address IP-address   指定该数据往哪个网口出去，这里主要是涉及多网卡的时候使用
  -k --key item-key          指定监控项的key值
  -h --help                       查看帮忙文档
  -V --version                   显示当前agent版本

#获取主机CPU负载
[root@filestore-v2 ~]# /data/application/zabbix-4.4./bin/zabbix_get -s 192.168.10.95 -k "system.cpu.load[all,avg1]"
0.140000

#获取当前主机名
[root@filestore-v2 ~]# /data/application/zabbix-4.4./bin/zabbix_get -s 192.168.10.95 -k system.uname
Linux sms-v2 3.10.-.el7.x86_64 # SMP Fri Apr  :: UTC  x86_64
