這里簡單總結一下Linux平臺Zabbix Agent的安裝配置,實驗測驗的Zabbix版本比較老了(Zabbix 3.0.9),不過版本雖然有點老舊,但是新舊版本的安裝步驟、流程基本差別不大,這里的總結僅僅當成一個操作手冊,后續會更新或添加部分內容,
Linux版本眾多,下面檔案僅僅在RHEL、CentOS幾個版本測驗過,不同版本可能安裝等有所差別,后續再補充完善,
1:首先檢查zabbix_server的版本
# zabbix_server --versionzabbix_server (Zabbix) 3.0.9
Revision 67444 19 April 2017, compilation time: Apr 23 2017 18:05:43
Copyright (C) 2017 Zabbix SIA
License GPLv2+: GNU GPL version 2 or later <http://gnu.org/licenses/gpl.html>.

the license. There is NO WARRANTY, to the extent permitted by law
2:檢查被監控服務器的Linux發行版本
例如 RHEL或CentOS
# more /etc/redhat-release
Red Hat Enterprise Linux Server release 5.7 (Tikanga)
# more /etc/issue
Oracle Linux Server release 5.7
Kernel \r on an \m
3: 根據Zabbix Server的版本和Linux發行版本選擇去下載對應的Zabbix Agent安裝包
這個測驗環境,我們就選擇下載zabbix-agent-3.0.9-1.el5.x86_64.rpm這個RMP包,下載地址為http://repo.zabbix.com/zabbix/3.0/rhel/5/x86_64/
# rpm -ivh zabbix-agent-3.0.9-1.el5.x86_64.rpmwarning: zabbix-agent-3.0.9-1.el5.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 79ea5ed4
Preparing... ########################################### [100%]1:zabbix-agent ########################################### [100%]
當然,如果服務器可以訪問外網,也可以使用下面命令直接安裝,
#rpm -ivh http://repo.zabbix.com/zabbix/3.0/rhel/5/x86_64/zabbix-agent-3.0.9-1.el5.x86_64.rpm
或者你配置了yum源,那就更簡單方便
#yum -y install zabbix-agent
我們知道,默認情況下Zabbix Server一般從客戶端主動獲取資料,當然客戶端也可以主動將資料推送給服務端,客戶端通過zabbix_sender指令來實作向服務端主動推送資料,這里不介紹zabbix_sender的安裝、配置,后續打算單獨介紹,
4:修改Zabbix-Agent的組態檔
首先找到zabbix_agentd.conf的位置,可以使用 rpm -ql zabbix-agent或 rpm -ql zabbix-agent | grep zabbix_agentd.conf
# rpm -ql zabbix-agent/etc/init.d/zabbix-agent
/etc/logrotate.d/zabbix-agent
/etc/zabbix/zabbix_agentd.conf
/etc/zabbix/zabbix_agentd.d
/etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf
/usr/sbin/zabbix_agentd
/usr/share/doc/zabbix-agent-3.0.9
/usr/share/doc/zabbix-agent-3.0.9/AUTHORS
/usr/share/doc/zabbix-agent-3.0.9/COPYING
/usr/share/doc/zabbix-agent-3.0.9/ChangeLog
/usr/share/doc/zabbix-agent-3.0.9/NEWS
/usr/share/doc/zabbix-agent-3.0.9/README
/usr/share/man/man8/zabbix_agentd.8.gz
/var/log/zabbix
/var/run/zabbix
# rpm -ql zabbix-agent | grep zabbix_agentd.conf/etc/zabbix/zabbix_agentd.conf
編輯引數檔案zabbix_agentd.conf
### Option: Server
# List of comma delimited IP addresses (or hostnames) of Zabbix servers.
# 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.
#
# Mandatory: no
# Default:
# Server=
Server=127.0.0.1 #用Zabbix_Server的IP地址替換127.0.0.1
### Option: ServerActive
# List of comma delimited IP:port (or hostname:port) pairs of Zabbix servers 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=127.0.0.1:20051,zabbix.domain,[::1]:30051,::1,[12fc::1]
#
# Mandatory: no
# Default:
# ServerActive=
ServerActive=127.0.0.1 #用Zabbix_Server的IP地址替換127.0.0.1
### 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=Zabbix server #Zabbix客戶端主機名替換Zabbix server
5:啟動Zabbix-agent服務
啟動Zabbix-Agent的幾種方式,注意實際環境,有些Linux版本并不支持下面的一些方式,
方式1:
# service zabbix-agent startStarting Zabbix agent: [ OK ]
# service zabbix-agent stopShutting down Zabbix agent: [ OK ]
# service zabbix-agent statuszabbix_agentd (pid 8120) is running...
方式2:
systemctl start zabbix-agent.service
systemctl stop zabbix-agent.service
方式3:
/etc/init.d/zabbix-agent start
/etc/init.d/zabbix-agent stop
/etc/init.d/zabbix-agent status
6: 設定zabbix-agent服務開機自啟動
# chkconfig --add zabbix-agent# chkconfig --list | grep zabbix-agentzabbix-agent 0:off 1:off 2:off 3:off 4:off 5:off 6:off
7: 檢查被監控的Linux服務器防火墻是否開通tcp 10050埠
這個非常簡單,不做過多闡述,但是必須檢查確認,否則Zabbix Server沒法獲取資料,
如果使用iptables管理管理防火墻,例如(CentOS 5,6)
修改組態檔,防火墻的組態檔/etc/sysconfig/iptables,新增下面這樣的一條配置
-A RH-Firewall-1-INPUT -p tcp --dport 10050 -j ACCEPT
重啟防火墻service iptables restart
如果使用firewalld管理防火墻(例如,CentOS 7.x)
firewall-cmd --zone=public --add-port=10050/tcp --permanent 添加埠
firewall-cmd --reload 重啟防火墻服務
firewall-cmd --query-port=10050/tcp,查詢某個埠是否開放
版本問題:
注意事項:關于Zabbix Server和Zabbix Agent的版本是否要一致問題,這個盡量一致,版本一致,可以避免雜七雜八的問題出現,官方檔案也有相關說明:Zabbix Server對Zabbix Agent是向下兼容的,但是要注意有些引數需要修改,請注意,高于3.0的Zabbix代理不能與Zabbix服務器3.0一起使用,具體如下所示:
12 Version compatibility
Supported agents
Zabbix agents from previous Zabbix versions are compatible with Zabbix 3.0. However, you may need to review the configuration of older agents as some parameters have changed, for example, parameters related to logging for versions before 3.0.
To take full advantage of new and improved items, improved performance and reduced memory usage, use the latest 3.0 agent.
Note that Zabbix agent newer than 3.0 cannot be used with Zabbix server 3.0.
雖然官方檔案提示高于3.0的Zabbix代理不能與Zabbix服務器3.0一起使用,但是不清楚是指大版本還是小版本,對于小版本,例如,我的測驗環境Zabbix Server為3.0.9,客戶端也可以安裝zabbix-agent-3.0.28這個版本,測驗暫未發現問題,
