server1:172.25.28.1 控制節點 rhel7.3 zabbix-server

server2:172.25.28.2 託管節點 rhel6.3 

server3:172.25.28.3 託管節點 rhel6.3

部署

對管理節點的要求

目前,只要機器上安裝了 Python 2.6 或 Python 2.7 (windows系統不可以做控制主機),都可以執行Ansible.

主機的系統可以是 Red Hat, Debian, CentOS, OS X, BSD的各種版本,等等.:
對託管節點的要求:
通常我們使用 ssh 與託管節點通訊，預設使用 sftp.如果 sftp 不可用，可在 ansible.cfg 配置檔案中配置成 scp 的方式. 在託管節點上也需要安裝 Python 2.4 或以上的版本.

server1,server2,server3的其他服務關閉，server1配置為zabbix-server

經過測試:server1，server2，server3可以互相連線

在管理節點上

1，安裝pip及相應的模組，這裡需要配置虛擬機器可以上網

[[email protected] ~]# easy_install pip

[[email protected] ~]# pip install paramiko PyYAML Jinja2 httplib2 six

2，採用yum源安裝:

[[email protected] ~]# yum install -y wget

[[email protected] ~]# wget http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

[[email protected] ~]# rpm -ivh epel-release-latest-7.noarch.rpm

[[email protected] ~]# yum install ansible

安裝完成

3，寫管理節點配置檔案

[[email protected] ansible]# vim hosts 

[[email protected] ansible]# pwd

/etc/ansible

測試

1，ansible Client -m ping     # 操作 Client 組 ( all 為操作 hosts 檔案中所有主機 )，-m 指定執行 ping 模組

2，執行本地指令碼

[[email protected] ~]# vim create.sh

[[email protected] ~]# cat create.sh 

#!/bin/bash

echo nihao > test1

-m指定模板 -a指定模板引數

託管節點檢視:
[[email protected] ~]# cat test1 

nihao

[[email protected] ~]# cat test1 

nihao

3，檢視 Client 分組主機記憶體使用情況

4，執行遠端指令碼

[[email protected] ~]# cat del.sh 

#!/bin/bash

rm -f test1 && echo ok!

[[email protected] ~]# cat del.sh 

#!/bin/bash

rm -f test1 && echo ok!

!!!!必須要給指令碼可執行許可權

[[email protected] ~]# ll test1

ls: cannot access test1: No such file or directory

[[email protected] ~]# ll test1

ls: cannot access test1: No such file or directory

利用Ansible-playbook自動部署zabbix-agent

使用 Ansible-playbook 可以完成一組複雜的動作，例如部署環境、搭建服務、修改配置等。

Playbooks 是 Ansible的配置,部署,編排語言.他們可以被描述為一個需要希望遠端主機執行命令的方案,或者一組IT程式執行的命令集合.

注意：這裡我新增一個server5:172.25.28.5，配置為和其他幾個server SSH免密

1,定義需要部署的主機

2，利用Playbooks寫Ansibles的部署語言

- hosts: test

  remote_user: root

  tasks:

  - name: copy install_packages to clien

    copy: src=/root/zabbix-agent-3.4.6-1.el6.x86_64.rpm  dest=/root/


  - name: install zabbix_agent packages

    yum: name=zabbix-agent-3.4.6-1.el6.x86_64.rpm state=present


  - name: modify shell

    copy : src=/root/zabbix_agent.sh  dest=/root/  mode=+x


  - name: shell

    command: /root/zabbix_agent.sh


  - name: start zabbix-agent

shell: /etc/init.d/zabbix-agent start

3，指令碼檔案

[[email protected] ~]# vim zabbix_agent.sh 

#!/bin/bash

#ip=$(ifconfig eth0 | awk -F " " '/inet\>/{print $2}' | awk -F ":" '{print $2}')

host_name=`hostname`

sed -i  97d  /etc/zabbix/zabbix_agentd.conf

sed -i "97i Server=$ip" /etc/zabbix/zabbix_agentd.conf

sed -i  138d  /etc/zabbix/zabbix_agentd.conf

sed -i "138i ServerActive=172.25.28.1" /etc/zabbix/zabbix_agentd.conf

sed -i  149d  /etc/zabbix/zabbix_agentd.conf

sed -i "149i Hostname=$host_name" /etc/zabbix/zabbix_agentd.conf

rm -rf /root/zabbix-agent-3.4.6-1.el6.x86_64.rpm

rm -rf /root/zabbix_agent.sh

4，執行

[[email protected] ~]# ansible-playbook zabbix_agent.yaml

5，檢視執行結果：

[[email protected] ~]# ls

[[email protected] ~]# netstat -antulpe | grep 10050

tcp        0      0 0.0.0.0:10050               0.0.0.0:*                   LISTEN      498        28137      5813/zabbix_agentd  

tcp        0      0 :::10050                    :::*                        LISTEN      498        28138      5813/zabbix_agentd  

[[email protected] ~]# /etc/init.d/zabbix-agent status

zabbix_agentd (pid  5813) is running...

[[email protected] ~]# ls

[[email protected] ~]# netstat -antulpe | grep 10050

tcp        0      0 0.0.0.0:10050               0.0.0.0:*                   LISTEN      498        11129      1763/zabbix_agentd  

tcp        0      0 :::10050                    :::*                        LISTEN      498        11130      1763/zabbix_agentd  

[[email protected] ~]# /etc/init.d/zabbix-agent status

zabbix_agentd (pid  1763) is running...

6，如果之前我們在瀏覽器配置了自動發現規則

可以看到如下結果
